Yes. Your HSA funds roll over from year to year with no limits or restrictions. Unlike Flexible Spending Accounts that force you to forfeit unused money, Health Savings Accounts allow every dollar to remain in your account indefinitely. The federal law under Internal Revenue Code Section 223 grants HSA owners complete control over their balances, and no use-it-or-lose-it rule applies to these accounts.
This rollover structure creates a powerful financial problem most Americans face when they contribute to employer-sponsored accounts. Section 125 of the Internal Revenue Code requires many Flexible Spending Accounts to operate under strict forfeiture rules, causing workers to lose an average of $339 per year in unused FSA contributions. The average HSA balance reached $6,489 at the end of 2024, demonstrating how rollover capabilities help account holders build substantial savings.

The Federal Law That Guarantees Your HSA Rolls Over
Internal Revenue Code Section 223 establishes that HSA funds remain the property of the account holder permanently. This federal statute differs fundamentally from Section 125 cafeteria plan rules governing FSAs. The law contains no expiration date, no annual forfeiture requirement, and no employer recapture provision. Your money stays yours whether you contribute $10 or reach the annual maximum.
The IRS guidance in Publication 969 confirms that HSA balances automatically carry forward each calendar year. No paperwork, no deadlines, and no action required on your part. The money accumulates continuously from the date you open the account until you withdraw it or pass away. This structure transforms the HSA from a simple spending account into a long-term wealth building tool.
The federal government designed this permanent rollover feature to encourage Americans to save for future medical expenses. Research from the Employee Benefit Research Institute shows that HSA assets reached $159 billion across 40 million accounts by mid-2025. This represents 16% year-over-year growth, demonstrating how the rollover structure motivates consistent saving behavior.
Unlike FSAs that employers own, your HSA belongs exclusively to you. The account administrator holds the funds as a custodian, but you retain complete ownership rights. This ownership distinction explains why rollovers occur automatically while FSA balances typically vanish on December 31.
How HSA Rollovers Work in Practice
Your HSA balance rolls over automatically when the calendar year ends. The custodian transfers the full balance from December 31 into January 1 without any action required from you. The process happens behind the scenes through electronic accounting systems that track your deposits, withdrawals, and investment earnings across multiple years.
Account holders can access their full balance on January 1 regardless of when they opened the account. A person who opens an HSA in November and deposits $500 will see that same $500 available in January, plus any additional contributions made during the new year. The IRS imposes contribution limits annually, but spending limitations operate independently of the calendar.
The rollover applies to both cash balances and invested assets. Investment assets reached $73 billion by mid-2025, representing 46% of all HSA assets. These investment holdings automatically roll forward each year, allowing stocks, bonds, and mutual funds to grow without triggering capital gains taxes or forced liquidation.
HSA providers must maintain records of your balance history across all years. This permanent record keeping enables you to claim reimbursement for medical expenses incurred years or decades earlier. The IRS allows tax-free withdrawals for qualified expenses at any future date, provided you maintain receipts proving the expense occurred after the HSA was established.
2026 Contribution Limits and How They Affect Rollovers
The IRS set 2026 HSA contribution limits at $4,400 for individuals with self-only coverage and $8,750 for those with family coverage. These limits increased $100 and $200 respectively from 2025. Account holders age 55 or older can contribute an additional $1,000 catch-up contribution, bringing their maximums to $5,400 for individuals and $9,750 for families.
Contribution limits apply only to new deposits, not to rollover balances. A person with a $10,000 balance from previous years can still contribute the full $4,400 in 2026. The annual limit restricts how much fresh money enters the account but places no cap on total accumulated wealth. This rule allows accounts to grow well beyond annual contribution maximums through rollovers and investment returns.
Your contribution limit gets prorated if you qualify for HSA eligibility for less than 12 months during the year. Someone eligible for only six months can contribute half the annual limit, or $2,200 for individual coverage in 2026. The proration applies month by month based on your eligibility status on the first day of each month.
Employer contributions count toward your annual limit. If your employer deposits $1,500 into your HSA in 2026 and you have individual coverage, you can only contribute $2,900 yourself to reach the $4,400 maximum. Exceeding the limit triggers a 6% excise tax on the excess amount that continues annually until corrected.
| Coverage Type | 2026 Limit | 2025 Limit | Catch-Up (55+) |
|---|---|---|---|
| Individual | $4,400 | $4,300 | $1,000 |
| Family | $8,750 | $8,550 | $1,000 |
The Critical Difference Between HSAs and FSAs
Flexible Spending Accounts operate under use-it-or-lose-it rules established by Section 125 of the Internal Revenue Code. These accounts require participants to forfeit unused balances at year end, though some employers offer either a 2.5-month grace period or allow a $680 carryover for 2026. The employer owns the FSA, giving them control over funds and preventing portability when you change jobs.
HSAs eliminate the forfeiture problem entirely. Every dollar you contribute stays in your account permanently, rolling over without limits or restrictions. You maintain ownership regardless of employment status, health plan changes, or retirement. The account functions more like an Individual Retirement Account with medical expense benefits than a temporary spending account.
FSA participants receive their full annual election on the first day of the plan year. Someone electing $3,300 for 2026 can immediately spend the entire amount even though contributions occur through payroll deductions over 12 months. HSA balances accumulate as you contribute, requiring you to build up funds before making large withdrawals.
You cannot invest FSA funds in stocks, bonds, or mutual funds. The money sits in a holding account earning no interest or returns. HSA funds can be invested once your balance exceeds the custodian’s minimum threshold, typically between $1,000 and $2,000. Investment earnings grow tax-free and contribute to your rollover balance each year.
Rollover Mechanics When Changing Jobs
Your HSA remains yours when you leave your job. The account travels with you automatically because you own it, not your employer. Employer contributions already deposited belong to you permanently, though future matching contributions stop immediately when employment ends.
You face three options when starting a new job with HSA benefits. You can keep your existing HSA and continue using it even if your new employer partners with a different custodian. You can open a second HSA through your new employer while maintaining the old account. You can roll over your old HSA into the new employer’s account to consolidate balances and potentially reduce fees.
The IRS permits only one HSA rollover per 12-month period when you receive the funds directly. This rollover involves your current custodian sending you a check or direct deposit, which you must then deposit into your new HSA within 60 days. Missing the deadline causes the full amount to become taxable income plus a 20% penalty if you’re under age 65.
Trustee-to-trustee transfers avoid the one-per-year limit. These transfers involve direct movement of funds between custodians without the money passing through your hands. The IRS treats trustee-to-trustee transfers as non-reportable events that don’t count toward rollover restrictions, don’t reduce contribution limits, and carry no 60-day deadline.
| Transfer Method | Annual Limit | 60-Day Rule | Reported to IRS |
|---|---|---|---|
| Standard Rollover | Once per 12 months | Yes | Yes, Form 8889 |
| Trustee-to-Trustee | Unlimited | No | No reporting needed |
Investment Options and How Rollovers Build Wealth
Most HSA custodians allow investment once your cash balance exceeds a minimum threshold. This threshold ranges from $1,000 to $2,000 depending on the provider. Investment options typically include index funds, mutual funds, exchange-traded funds, individual stocks, bonds, and target-date retirement funds.
About 4 million HSA holders invest their funds, representing 10% of all accounts. These investing account holders maintain an average combined balance of $22,635 in deposits and investments. Non-investing account holders average just $2,469, demonstrating how investment growth multiplies the benefits of annual rollovers.
Investment earnings accumulate tax-free inside the HSA and roll over automatically each year. Capital gains, dividends, and interest never trigger tax consequences provided the money stays in the account or gets spent on qualified medical expenses. This tax treatment creates a triple tax advantage where contributions reduce taxable income, growth occurs tax-free, and withdrawals for medical expenses avoid taxation.
Index funds tracking the S&P 500 offer low-cost diversification suitable for long-term HSA growth. These funds typically charge expense ratios between 0.03% and 0.20% annually. Dividend-focused funds provide another option for investors seeking established companies with proven profitability, though dividends inside an HSA avoid the tax burden they carry in taxable accounts.
Target-date funds automatically adjust asset allocation as you approach retirement. Someone planning to use HSA funds at age 65 might select a 2050 or 2055 target-date fund that gradually shifts from stocks to bonds. Many HSA providers charge investment fees ranging from 0.25% to 0.50% of invested assets annually, plus fund expense ratios.
State Tax Treatment in California and New Jersey
California and New Jersey do not conform to federal HSA tax treatment. These two states treat HSA contributions as taxable income for state purposes, even though contributions remain tax-deductible federally. HSA contributions appear as standard compensation on your W-2 Box 16 for state wages in these jurisdictions.
California taxes all earnings inside your HSA. Interest payments, dividend distributions, and capital gains from selling investments all count as taxable income on your California state return. You must manually track these earnings because HSA custodians don’t issue 1099 forms for tax-exempt federal accounts, leaving California residents responsible for calculating and reporting the amounts.
New Jersey applies similar rules treating HSA contributions and earnings as taxable for state purposes. The state requires you to add back HSA deductions when calculating New Jersey taxable income. Employer contributions to your HSA also count as taxable compensation in both states, subject to state withholding and payroll taxes.
Alabama previously taxed HSAs but conformed to federal treatment starting in 2018. All other states either follow federal rules or impose no state income tax. California and New Jersey residents still benefit from federal tax savings and rollover capabilities, but they forfeit the state tax advantages available to residents of 48 other states.
Medicare Enrollment and the Six-Month Trap
Enrollment in any part of Medicare terminates HSA eligibility immediately. Medicare Part A, Part B, Part C, and Part D all qualify as disqualifying coverage under Internal Revenue Code Section 223. You must stop HSA contributions the month your Medicare coverage begins, even if you continue working and maintain high-deductible health insurance through your employer.
Medicare Part A enrolls automatically when you claim Social Security retirement benefits. The government provides no opt-out option for this premium-free hospital coverage. Individuals receiving Social Security at age 65 automatically lose HSA eligibility due to this mandatory enrollment, creating problems for workers who want to continue contributing while employed past age 65.
Medicare enrollment applies retroactively for up to six months when you enroll after age 65. Someone who applies for Medicare at age 66 receives coverage dating back six months or to their 65th birthday, whichever is closer. Any HSA contributions made during this retroactive period become excess contributions subject to the 6% annual excise tax.
You should stop HSA contributions at least six months before applying for Medicare to avoid the retroactive trap. This creates a difficult situation for workers who need to balance continued HSA contributions against delayed Medicare enrollment. HSA funds accumulated before Medicare remain available for qualified expenses throughout retirement, including Medicare premiums, deductibles, and prescription costs.
Age 65 Rules Transform Your HSA
HSA withdrawal rules change dramatically when you turn 65. The 20% penalty for non-qualified withdrawals disappears completely, though you still owe ordinary income tax on amounts spent for non-medical purposes. Your HSA functions like a traditional IRA for non-medical spending after 65, providing penalty-free access to accumulated funds while maintaining tax-free treatment for medical expenses.
Withdrawals for qualified medical expenses remain completely tax-free at age 65 and beyond. Doctor visits, prescriptions, dental care, vision expenses, and medical equipment all qualify for tax-free reimbursement regardless of your age. You can use HSA funds to pay Medicare Part B and Part D premiums, Medicare Advantage premiums, and long-term care insurance premiums within IRS limits.
The IRS limits tax-free withdrawals for long-term care insurance based on age. Someone aged 61-70 can withdraw up to $4,770 tax-free for long-term care premiums in 2023, while those 71 or older can withdraw $5,960. These limits adjust annually for inflation. Premium payments for Medicare supplement policies do not qualify for tax-free HSA withdrawals under current IRS rules.
Many retirees use their HSA as a supplementary retirement account by letting balances roll over for decades. This strategy works particularly well for individuals with low medical expenses during working years. You can reimburse yourself decades later for medical expenses incurred years earlier, provided you maintain receipts and the expenses occurred after your HSA was opened.
Three Common Rollover Scenarios
Scenario 1: Young Professional Building Long-Term Savings
Sarah earns $65,000 annually and enrolls in her employer’s high-deductible health plan at age 28. She contributes $3,000 to her HSA each year while her employer adds $1,000. Sarah spends only $800 annually on medical expenses, letting $3,200 roll over each year.
| Action | Result |
|---|---|
| Contributes $4,000 total annually ($3,000 employee + $1,000 employer) | Reduces federal taxable income by $4,000, saving $880 in taxes at 22% bracket |
| Spends $800 on medical expenses | Uses tax-free funds for immediate needs |
| Rolls over $3,200 annually for 10 years | Accumulates $32,000 plus investment growth before age 38 |
| Invests rollover balance in S&P 500 index fund | Achieves 10% average annual return, growing balance to $54,868 by age 38 |
Scenario 2: Family Managing High Medical Costs
Marcus and his wife have two children and face $6,000 in annual medical expenses for prescriptions, dental work, and doctor visits. They contribute the family maximum of $8,750 in 2026 and spend $6,000, rolling over $2,750.
| Action | Result |
|---|---|
| Contributes $8,750 (family maximum) | Saves $2,363 in federal taxes at 27% bracket plus $669 in FICA taxes |
| Pays $6,000 in qualified medical expenses tax-free | Avoids paying income tax on $6,000, saving $1,620 at 27% bracket |
| Rolls over $2,750 | Builds emergency fund for future large medical expenses |
| Maintains rollover balance in cash reserve | Ensures funds available for unexpected medical costs without penalty |
Scenario 3: Pre-Retiree Maximizing Retirement Healthcare Funds
Jennifer turns 55 and contributes the maximum $5,400 for individual coverage including the $1,000 catch-up contribution. She pays medical expenses from her taxable income and lets her entire HSA balance roll over for 10 years until retirement at 65.
| Action | Result |
|---|---|
| Contributes $5,400 annually for 10 years | Deposits total of $54,000 |
| Pays medical expenses out-of-pocket | Preserves $3,000 annually in receipts for future reimbursement |
| Invests all HSA contributions | Achieves $89,716 balance at 65 with 8% average annual return |
| Reimburses $30,000 in saved medical receipts at age 66 | Takes $30,000 completely tax-free, leaving $59,716 for future expenses |
Qualified Medical Expenses Your Rollover Balance Can Cover
The IRS defines qualified medical expenses as costs incurred for diagnosis, cure, mitigation, treatment, or prevention of disease. Your HSA covers medical, dental, and vision expenses for yourself, your spouse, and tax dependents even if they’re not covered by your high-deductible health plan.
Medical expenses eligible for HSA reimbursement include doctor visits, hospital stays, surgeries, prescription medications, insulin, medical equipment, ambulance services, laboratory fees, and diagnostic tests. Mental health treatment qualifies, including psychiatric care, psychological counseling, and substance abuse treatment programs.
Dental expenses covered by HSA funds include cleanings, examinations, X-rays, fillings, extractions, root canals, dentures, orthodontics like braces, and dental surgery. Vision expenses qualify, including eye examinations, prescription glasses, contact lenses and solution, LASIK surgery, and prescription sunglasses.
Over-the-counter medications became HSA-eligible without requiring prescriptions after the CARES Act passed in 2020. Feminine hygiene products, pain relievers, cold medicines, allergy medications, and first aid supplies all qualify. Personal protective equipment including masks, hand sanitizer, and sanitizing wipes qualified as medical expenses during and after the COVID-19 pandemic.
Certain insurance premiums qualify for tax-free HSA withdrawals under specific circumstances. Medicare Part A, Part B, Part D, and Medicare Advantage premiums qualify if you’re 65 or older. COBRA continuation coverage premiums qualify. Health insurance premiums while receiving unemployment compensation qualify. Long-term care insurance premiums qualify within age-based IRS limits.
Mistakes That Destroy Rollover Benefits
Mistake 1: Contributing After Medicare Enrollment
The most expensive error involves contributing to your HSA after Medicare coverage begins. The 6% excise tax applies annually to these excess contributions until withdrawn. Someone who contributes $4,400 after enrolling in Medicare pays $264 the first year, plus $264 each subsequent year until correction.
Mistake 2: Exceeding Annual Contribution Limits
Contributing more than the IRS annual limit triggers a 6% penalty on the excess amount. This penalty continues every year the excess remains in your account. You can correct the error by withdrawing the excess plus any earnings before your tax filing deadline, or by applying the excess to a future year’s contribution limit.
Mistake 3: Missing the 60-Day Rollover Deadline
Taking a distribution from your HSA with plans to roll it over creates a strict 60-day deadline. Missing this deadline causes the entire distribution to become taxable income plus a 20% penalty if you’re under 65. The one-rollover-per-year rule means you cannot attempt another rollover for 12 months after receiving the funds.
Mistake 4: Failing to Track California and New Jersey Earnings
California and New Jersey residents must report all interest, dividends, and capital gains from their HSA on state tax returns. HSA custodians don’t send 1099 forms for federally tax-exempt earnings, making it your responsibility to calculate and report these amounts. Failing to report triggers state tax penalties and interest.
Mistake 5: Using HSA Funds for Non-Qualified Expenses Before 65
Withdrawing HSA money for non-medical purposes before age 65 results in income tax plus a 20% penalty on the withdrawal amount. A $2,000 withdrawal for a vacation costs $440 in penalties at the 22% tax bracket, plus the 20% additional tax of $400. You can correct mistaken distributions by returning the funds to your HSA before April 15 of the following year.
Mistake 6: Forgetting to Document Expenses
The IRS requires you to substantiate that HSA withdrawals paid for qualified medical expenses. Lacking receipts, invoices, or explanation of benefits forms during an audit causes the withdrawal to become taxable income plus penalties. You should maintain expense documentation indefinitely, particularly if you plan to claim reimbursement years after the expense occurred.
Mistake 7: Claiming Employer Seed Money Not Yet Deposited
Some employers structure HSA contributions as matching funds or seed contributions deposited at specific times. Leaving your job before these scheduled deposits occurs means forfeiting the promised money. Only employer contributions actually in your account belong to you when employment ends.
Mistake 8: Not Adjusting Contributions Mid-Year
Your contribution limit gets prorated when you lose HSA eligibility during the year. Someone eligible for nine months can contribute only 75% of the annual limit. Failing to adjust your contributions creates an excess contribution subject to the 6% annual penalty.
IRA-to-HSA Rollover Rules
The IRS permits a one-time qualified HSA funding distribution from your traditional or Roth IRA to your HSA. This special rollover can occur only once in your lifetime except in rare circumstances. The rollover amount counts toward your annual HSA contribution limit for the year, reducing how much you can contribute from other sources.
You must maintain HSA eligibility for 12 months after completing an IRA-to-HSA rollover. This testing period begins the month you receive the rollover funds and ends on the last day of the 12th month. Losing eligibility during the testing period causes the rolled-over amount to become taxable income subject to a 10% penalty.
SEP IRAs and SIMPLE IRAs do not qualify for HSA rollovers under current IRS rules. Only traditional IRAs and Roth IRAs meet the requirements. The account owner must be the same person for both the IRA and the HSA, preventing spouses from rolling money between each other’s accounts.
This rollover strategy makes sense for people who have excess IRA balances and want to maximize tax-free medical expense coverage. The rolled-over funds convert from tax-deferred treatment to tax-free treatment when spent on qualified medical expenses. You sacrifice future retirement income from the IRA in exchange for expanded tax-free healthcare spending capability.
Pros and Cons of HSA Rollover Capability
| Advantages | Disadvantages |
|---|---|
| Unlimited accumulation: Your balance grows indefinitely without forced withdrawals or expiration dates, unlike FSAs that forfeit unused funds annually | High-deductible requirement: You must maintain enrollment in a qualified HDHP to contribute, limiting your health plan choices and potentially increasing out-of-pocket costs |
| Tax-free investment growth: Rolled-over funds can be invested in stocks, bonds, and mutual funds with all earnings completely exempt from capital gains taxes | Contribution limits restrict accumulation speed: The $4,400 individual and $8,750 family limits mean building large balances requires many years of consistent contributions and rollovers |
| Complete portability: The account follows you through job changes, retirement, and health plan switches without forfeiture or penalties | Medicare enrollment ends contributions: You must stop contributing when Medicare begins, typically preventing HSA deposits after age 65 even if you continue working |
| Retirement healthcare fund: Rolled-over balances create a dedicated pool for medical expenses in retirement when healthcare costs typically increase dramatically | State tax complications: California and New Jersey residents lose state tax benefits and must track earnings manually for state return reporting |
| Penalty-free access at 65: Non-medical withdrawals after age 65 avoid the 20% penalty while maintaining tax-free status for medical expenses | Complex eligibility rules: Mid-year eligibility changes, Medicare retroactive coverage, and testing periods create numerous opportunities for costly errors |
| Reimbursement flexibility: You can pay expenses out-of-pocket and reimburse yourself from rollover balances years or decades later | Investment risk exposure: Market downturns can reduce rolled-over balances, potentially leaving insufficient funds when medical emergencies occur |
| Estate planning benefits: Spouses can inherit HSAs with full tax advantages, preserving rollover benefits across generations | Documentation burden: The IRS requires detailed expense records maintained indefinitely, creating administrative hassle and audit risk |
Do’s and Don’ts for Maximizing Rollover Benefits
Do: Contribute the Maximum Amount Annually
Maximize your contributions each year to take full advantage of rollover capabilities. The tax deduction reduces your current tax bill while the rollover builds future medical expense reserves. Consistent maximum contributions create a powerful compounding effect when combined with investment growth.
Do: Invest Your Rollover Balance for Long-Term Growth
Transfer funds above your cash reserve into investment options offered by your HSA custodian. Index funds tracking broad market indexes provide low-cost diversification suitable for balances you won’t need for several years. Investment returns dramatically increase the value of annual rollovers.
Do: Pay Small Medical Expenses Out-of-Pocket
Preserve your HSA balance by paying current expenses from taxable income when financially feasible. Save the receipts for future tax-free reimbursement. This strategy maximizes the rollover amount available for investment and long-term growth.
Do: Request Trustee-to-Trustee Transfers When Consolidating Accounts
Direct transfers between custodians avoid the 60-day deadline and one-per-year limitation. Contact your current HSA provider and request they transfer funds directly to your new custodian. This method eliminates the risk of missing deadlines or triggering penalties.
Do: Keep Detailed Records of All Medical Expenses
Maintain receipts, invoices, and explanation of benefits statements for every medical expense you incur. Store documents electronically with backup copies. These records enable you to claim tax-free reimbursement from your rollover balance years or decades later.
Don’t: Contribute After Enrolling in Medicare
Stop all HSA contributions the month Medicare coverage begins, even if you continue working. The 6% annual excise tax on excess contributions costs far more than the tax benefit of contributing. Calculate your prorated contribution limit based on the number of months before Medicare enrollment.
Don’t: Wait Until December to Use Your FSA
If you have both an FSA and an HSA through different employers or family coverage, remember that FSAs don’t roll over like HSAs. Spend FSA funds before the year ends or during the grace period. Use your HSA for expenses after the FSA runs out to maximize rollover benefits.
Don’t: Take Standard Rollovers More Than Once Per Year
The IRS restricts standard rollovers where you receive the funds to once every 12 months. Taking a second rollover within this period makes the distribution taxable income plus penalties. Use trustee-to-trustee transfers for multiple account consolidations.
Don’t: Forget About the Six-Month Medicare Retroactive Period
Medicare coverage applies retroactively up to six months when you enroll after age 65. Stop HSA contributions at least six months before applying for Medicare to avoid creating excess contributions during the retroactive period. This rule catches many people by surprise and triggers expensive penalties.
Don’t: Assume All Health Expenses Qualify
The IRS maintains strict definitions of qualified medical expenses. Cosmetic procedures, gym memberships, and general health items typically don’t qualify unless treating a specific diagnosed medical condition. Verify expense eligibility before withdrawing rollover funds to avoid taxes and penalties.
Filing Requirements and Tax Reporting
You report HSA contributions and distributions on IRS Form 8889, which attaches to your Form 1040. Line 14a reports total distributions for the year, including any rollovers or transfers. Line 14b specifically identifies rollover contributions, which don’t count toward your annual contribution limit but must be reported for IRS tracking purposes.
Your HSA custodian sends Form 5498-SA by May 31 showing contributions made during the tax year and the previous year up to the tax filing deadline. This form reports employer contributions, personal contributions, and rollover contributions. The custodian also sends Form 1099-SA showing distributions from your account, including the gross distribution amount and distribution codes indicating the reason for withdrawal.
Excess contributions require Form 5329 to calculate the 6% excise tax. This form attaches to your Form 1040 and reports both the excess contribution amount and the resulting penalty. You must file Form 5329 annually until the excess contribution is withdrawn or absorbed by undercontributing in a future year.
California and New Jersey residents must add back HSA contributions when calculating state taxable income. The contributions appear on Line 13 of federal Form 1040 as an adjustment to income, but you must include them as state income. Track your HSA earnings separately from custodian statements and report them as interest income or dividend income on your state return.
How High-Deductible Health Plan Requirements Affect Rollovers
You must be covered by a qualified high-deductible health plan to make HSA contributions. For 2026, qualified HDHPs have minimum deductibles of $1,700 for individual coverage and $3,400 for family coverage. Maximum out-of-pocket limits cannot exceed $8,500 for individuals and $17,000 for families in 2026.
You cannot contribute to an HSA if you have other health coverage that provides benefits before meeting the HDHP deductible. General purpose FSAs, Health Reimbursement Arrangements covering medical expenses, and Medicare all disqualify you from making contributions. Your existing HSA balance and rollovers remain available for spending even when you cannot make new contributions.
Limited-purpose FSAs covering only dental and vision do not disqualify you from HSA contributions. Dependent care FSAs also remain compatible with HSA eligibility. Some employers offer limited-purpose healthcare FSAs specifically designed to work alongside HSAs.
Eligibility is determined monthly based on your coverage status on the first day of each month. Someone who enrolls in an HDHP on June 15 becomes HSA-eligible on July 1. Losing HDHP coverage mid-month doesn’t affect eligibility for that month because you maintained coverage on the first day.
The Last-Month Rule and Testing Period
The last-month rule allows you to contribute the full annual maximum if you’re HSA-eligible on December 1, even if you weren’t eligible the entire year. This rule helps people who start new jobs late in the year or switch to HDHPs during open enrollment. Using the last-month rule triggers a testing period requiring you to maintain HSA eligibility for the entire following year.
The testing period runs from December 1 of the year you make the full contribution through December 31 of the following year. Someone who becomes HSA-eligible on December 1, 2026 and contributes the full $4,400 must remain eligible through December 31, 2027. Failing the testing period causes the excess contributions to become taxable income subject to a 10% penalty.
Medicare enrollment during the testing period triggers the failure penalties. This creates particular problems for people who turn 65 during the testing period and enroll in Medicare. You can avoid testing period problems by contributing only the prorated amount based on your actual months of eligibility rather than using the last-month rule.
The testing period only applies when you use the last-month rule to contribute more than your prorated amount. Someone eligible for all 12 months who contributes the maximum faces no testing period because they didn’t exceed their normal contribution limit.
FSA-to-HSA Transitions and Carryover Rules
Switching from an FSA to an HSA during open enrollment requires careful planning. General purpose healthcare FSAs disqualify you from making HSA contributions because they provide benefits before meeting the HDHP deductible. You must exhaust your FSA balance or convert it to a limited-purpose FSA covering only dental and vision before becoming HSA-eligible.
Some employers allow FSA carryovers up to $680 for the 2026 plan year. These carryover amounts automatically convert to limited-purpose FSA funds if you enroll in an HDHP with HSA the following year. The limited-purpose FSA carryover covers only dental and vision expenses while you build your HSA balance through contributions and rollovers.
You cannot transfer FSA balances directly into an HSA. The two account types operate under completely different tax rules and regulatory frameworks. Spend down your FSA balance before the plan year ends or during any grace period offered by your employer to avoid forfeiting the money.
Grace periods extend 2.5 months beyond the plan year end, typically through March 15. FSA plans offer either a grace period or a carryover, never both. Using an FSA grace period to spend medical expenses delays HSA eligibility until the grace period expires or you exhaust the FSA balance.
Bronze and Catastrophic Plan Expansion for 2026
The One Big Beautiful Bill Act created the largest HSA expansion since the accounts launched in 2003. Starting January 1, 2026, Bronze and Catastrophic Affordable Care Act plans qualify as HSA-eligible high-deductible health plans. This change opens HSA access to millions of Americans who previously couldn’t contribute due to plan structure incompatibilities.
Bronze plans typically offer the lowest premiums on ACA exchanges and cover 60% of expected medical costs. Catastrophic plans provide coverage only for extreme medical expenses after a very high deductible. Both plan types now meet IRS requirements for HSA eligibility, expanding the pool of qualified plans significantly.
Direct Primary Care memberships also became HSA-compatible under the 2026 rules. These memberships charge monthly fees for unlimited primary care access without insurance involvement. Telehealth coverage became permanently compatible with HSA eligibility, allowing zero-deductible telehealth benefits without disqualifying the underlying HDHP.
These expansions increase rollover opportunities by making HSAs accessible to more Americans. Someone previously unable to contribute due to plan restrictions can now open an HSA, make contributions, and begin building rollover balances for future medical expenses and retirement.
