No, a reverse mortgage itself does not directly affect or create a capital gains tax. The money you receive is a loan, not income.1 A capital gains tax is only triggered when the home is sold to repay that loan, and only if the sale results in a profit.3
The primary conflict arises from a specific federal law: Internal Revenue Code § 1014, also known as the “stepped-up basis” rule.5 This rule creates a massive tax advantage exclusively for heirs, wiping out decades of taxable appreciation on the property after the owner’s death.7 This creates a stark financial divide, where a homeowner selling their property could face a huge tax bill, while their child selling the exact same house months later could pay nothing.
This distinction is critical because for the vast majority of American seniors, their home equity represents their single largest financial asset, often dwarfing their retirement savings and other investments. Understanding how this rule interacts with a reverse mortgage is paramount to preserving that wealth.

The Two Pillars: Understanding Reverse Mortgages and Capital Gains
What Exactly is a Reverse Mortgage and Who Holds the Power?
A reverse mortgage is a special type of loan designed for homeowners aged 62 and older.8 It allows you to access a portion of your home’s equity—the value you own free and clear—and turn it into cash.8 You don’t have to make monthly payments back to the lender.9
The most common type of reverse mortgage is the Home Equity Conversion Mortgage (HECM), which is insured by a key government entity: the Federal Housing Administration (FHA).11 This federal insurance is the most important protection you have. It guarantees that even if your loan balance grows to be more than your home is worth, neither you nor your heirs will ever have to pay the difference.13
The reason these loans exist is to help seniors who are often “house-rich but cash-poor.”8 Many older adults have significant wealth tied up in their homes but have limited monthly income to cover expenses.15 A reverse mortgage provides liquidity to help them pay for healthcare, home repairs, or daily living costs while allowing them to “age in place” in their own homes.8
The core trade-off is that your loan balance grows over time.9 Each month, interest and fees are added to the amount you owe, which means the amount of equity you have in your home shrinks.9 This directly reduces the amount of money that will be left for you or your heirs when the home is eventually sold to repay the loan.17
The Tax Man’s Formula: Unpacking Capital Gains on Your Home
Your home is considered a capital asset by the Internal Revenue Service (IRS).3 When you sell a capital asset for more than you have invested in it, that profit is called a capital gain, and it can be taxed.18
The formula the IRS uses to determine your profit is simple on the surface but has hidden depths. It is not just what you sell it for minus what you paid for it.
The official calculation is: Amount Realized (Sale Price) – Adjusted Basis = Capital Gain
The “Amount Realized” is simply the sale price of your home.20 The tricky part, and the number you have the most control over, is the “Adjusted Basis.”
Your Most Important Number: Calculating Your “Adjusted Basis”
Your home’s basis is its original cost to you.18 This includes the purchase price plus some of the settlement fees and closing costs you paid when you bought it, like recording fees and title insurance.22
However, that number isn’t static. Over the years, you adjust it, creating your adjusted basis.21 You increase your basis by the cost of any capital improvements you make. A capital improvement is a major project that adds value to your home or extends its life, such as a new roof, a kitchen remodel, a room addition, or a new HVAC system.23
This is incredibly important. Every dollar you spend on a qualifying improvement increases your basis, which in turn reduces your taxable profit by that same dollar amount. Failing to keep detailed records and receipts for these improvements means you are voluntarily choosing to pay more in taxes than the law requires.
The “Get Out of Tax Free” Card: Your §121 Primary Residence Exclusion
The U.S. government provides a massive tax break to encourage homeownership. This powerful rule, found in §121 of the Internal Revenue Code, allows most homeowners to exclude a huge portion of their profit from being taxed when they sell their primary home.13
For single individuals, you can exclude up to $250,000 of the capital gain.14 For married couples who file their taxes together, that amount doubles to $500,000.14 This means a married couple could have a half-million-dollar profit on their home sale and pay zero federal capital gains tax.
To qualify for this powerful exclusion, you must pass two simple tests. First, the Ownership Test: you must have owned the home for at least two years during the five-year period ending on the date of sale.23 Second, the Use Test: you must have lived in the home as your main residence for at least two years during that same five-year period.23
The Homeowner’s Story: Selling Your Home with a Reverse Mortgage
The Moment of Truth: How a Sale Triggers the Tax Clock
When you decide to sell your home, the reverse mortgage loan becomes due and must be paid off entirely at the closing.26 The tax calculation, however, happens completely separately from the loan repayment. The IRS determines your profit based on the sale price and your adjusted basis, regardless of any loans on the property.
A very common and costly mistake is to believe that the reverse mortgage balance reduces your taxable profit. It does not. The loan is simply a debt that gets settled from the sale proceeds. Your capital gain is calculated on the full sale price, before any debts are paid.
Real-World Scenarios: Calculating Your Own Capital Gains Tax
Let’s walk through the three most common situations a homeowner with a reverse mortgage will face when they sell.
Scenario 1: The Win-Win—Gain is Completely Wiped Out by the Exclusion
Imagine a married couple, John and Mary, bought their home 40 years ago. They have lived there ever since and now decide to sell to move into a smaller condo.
| Calculation Step | Details and Result |
| Original Purchase Price | $80,000 |
| Capital Improvements | + $70,000 (new kitchen, windows, and a deck) |
| Adjusted Basis | $150,000 ($80,000 + $70,000) |
| Sale Price | $600,000 |
| Reverse Mortgage Balance | $180,000 |
| Capital Gain | $450,000 ($600,000 Sale Price – $150,000 Adjusted Basis) |
| §121 Exclusion | $500,000 (Married Couple Filing Jointly) |
| Taxable Gain | $0 ($450,000 is less than the $500,000 exclusion) |
| Final Outcome | John and Mary pay $0 in federal capital gains tax. From the $600,000 sale, they pay off the $180,000 loan and walk away with $420,000 in cash, tax-free. |
Scenario 2: The Partial Hit—When Your Profit Exceeds the Exclusion
Now consider Susan, a single individual who has lived in a rapidly appreciating area for many years. She also decides to sell her home.
| Calculation Step | Details and Result |
| Original Purchase Price | $150,000 |
| Capital Improvements | + $50,000 (bathroom remodel and new roof) |
| Adjusted Basis | $200,000 ($150,000 + $50,000) |
| Sale Price | $600,000 |
| Reverse Mortgage Balance | $120,000 |
| Capital Gain | $400,000 ($600,000 Sale Price – $200,000 Adjusted Basis) |
| §121 Exclusion | $250,000 (Single Filer) |
| Taxable Gain | $150,000 ($400,000 Gain – $250,000 Exclusion) |
| Final Outcome | Susan has a $150,000 taxable long-term capital gain. She will owe federal and potentially state taxes on this amount. After paying off her $120,000 loan, she receives $480,000, from which she must pay her tax bill. |
Scenario 3: The “Underwater” Escape—Protected by the Non-Recourse Feature
This scenario highlights the most critical protection of a HECM reverse mortgage. Let’s say Robert took out a reverse mortgage years ago, but a local market downturn has caused his home’s value to fall.
| Financial Event | Outcome |
| Adjusted Basis | $120,000 |
| Reverse Mortgage Balance | $350,000 (has grown over many years) |
| Current Home Value & Sale Price | $300,000 |
| Loan Settlement | The home sells for $300,000. All proceeds go to the lender. The remaining $50,000 of debt is forgiven. |
| Tax Calculation | Robert’s capital gain is $180,000 ($300,000 Sale Price – $120,000 Basis). This is fully covered by his $250,000 exclusion, so his taxable gain is $0. |
| Final Outcome | Because HECMs are non-recourse loans, Robert is not personally liable for the $50,000 shortfall.28 The FHA insurance covers it.12 He walks away with no cash, but more importantly, no debt and no tax bill. |
The Heirs’ Inheritance: A Completely Different Set of Tax Rules
The Clock Starts Ticking: What Heirs Must Do When the Loan Comes Due
When the last surviving borrower on a reverse mortgage passes away, the loan immediately becomes due and payable.17 The lender will send a formal “Due and Payable Notice” to the estate or the heirs.17 This notice officially starts the clock on a strict timeline.
Heirs typically have only 30 days from receiving this notice to inform the lender of their intentions.15 From there, they generally have six months to fully resolve the loan.17 If they are actively trying to sell the property or secure financing, they can request up to two 90-day extensions, giving them a maximum of one year.31
Ignoring these deadlines is a critical mistake. Lenders are financially penalized by the Department of Housing and Urban Development (HUD) if they don’t follow these timelines precisely, so they are highly motivated to initiate foreclosure if the heirs are unresponsive.
The Three Critical Choices Facing Every Heir
Heirs are never personally responsible for the reverse mortgage debt.13 Their obligation is limited to the value of the home itself. They face three distinct choices.
| Option | What It Means | Key Consideration |
| 1. Keep the Home | The heirs must pay off the loan balance. A special protection allows them to pay the lesser of the full loan balance or 95% of the home’s current appraised value.12 | This requires having cash available or the ability to qualify for a new, traditional mortgage to refinance the debt. |
| 2. Sell the Home | This is the most common path. The heirs sell the property on the open market. The loan is paid off at closing, and any leftover equity belongs to the heirs.17 | If the home sells for less than the loan balance, the non-recourse feature protects the estate from owing the difference.13 |
| 3. Walk Away | If the loan is “underwater” (worth less than the debt) and the heirs don’t want to sell it themselves, they can sign a Deed-in-Lieu of Foreclosure.15 | This action voluntarily transfers ownership to the lender, satisfies the debt completely, and releases the estate from any further obligation.33 |
The Ultimate Tax Shield: How “Stepped-Up Basis” Wipes the Slate Clean for Heirs
Here is where the rules change completely, all thanks to Internal Revenue Code § 1014. This law states that when an heir inherits property, the tax basis is “stepped up” from the original owner’s adjusted basis to the property’s fair market value (FMV) on the date of death.24
This single rule is the most powerful tax advantage available in estate planning. It effectively erases a lifetime of appreciation for tax purposes. All the capital gain that built up while the parent owned the home simply vanishes from the IRS’s perspective.
When the heir sells the property, their capital gain is calculated from this new, much higher, stepped-up basis. If they sell the home within a few months of inheriting it, the sale price is likely to be very close to the date-of-death value. This results in little to no taxable gain, and therefore, little to no capital gains tax.7
Heirs in Action: Seeing the Stepped-Up Basis at Work
Let’s revisit Susan’s house from the earlier example, but this time, imagine she passes away and her son, David, inherits the property.
Scenario 1: The Quick Sale—Almost No Tax Due
David decides to sell the home shortly after inheriting it to settle the estate.
| Tax Calculation | Amount |
| Parent’s Original Adjusted Basis | $200,000 |
| Fair Market Value at Death | $600,000 |
| Heir’s New “Stepped-Up” Basis | $600,000 (The old basis is now irrelevant) |
| Sale Price (2 months later) | $610,000 |
| Reverse Mortgage Balance | $120,000 |
| Capital Gain for Heir | $10,000 ($610,000 Sale Price – $600,000 Stepped-Up Basis) |
| Final Outcome | David has a small, taxable long-term capital gain of $10,000. From the $610,000 sale, he pays off the $120,000 loan and receives $490,000, from which he’ll pay a minor tax bill. Without the step-up, his gain would have been a staggering $410,000. |
Scenario 2: The Delayed Sale—Paying Tax on New Appreciation
Now, let’s say David decides to keep the house for a few years before selling.
| Tax Calculation | Amount |
| Heir’s Stepped-Up Basis | $600,000 (This number is locked in from the date of death) |
| Sale Price (3 years later) | $800,000 |
| Reverse Mortgage Balance | $120,000 (This does not change) |
| Capital Gain for Heir | $200,000 ($800,000 Sale Price – $600,000 Stepped-Up Basis) |
| Final Outcome | David’s taxable gain is $200,000. This represents the appreciation that occurred after he inherited the property. After paying the $120,000 loan, he receives $680,000, but now faces a significant capital gains tax bill on his $200,000 profit. |
Navigating Dangers and Special Circumstances
The Nightmare Scenario: Foreclosure and “Phantom Gain”
A reverse mortgage can go into default if the borrower fails to meet their core responsibilities: paying property taxes, maintaining homeowners insurance, or keeping the home in good repair.28 If this happens, the lender can initiate foreclosure. For tax purposes, the IRS treats a foreclosure as a sale.36
This is where a strange and counter-intuitive tax rule comes into play for non-recourse loans like HECMs. The IRS states that the “Amount Realized” in a non-recourse foreclosure is the full outstanding loan balance at that time, even if it’s higher than the home’s actual market value.37 This can create a “phantom gain” on paper, where you have a taxable profit even though you received no cash and lost the home.
| Foreclosure Tax Step | Example Result |
| Homeowner’s Adjusted Basis | $150,000 |
| Reverse Mortgage Balance | $380,000 |
| Home’s Fair Market Value | $320,000 |
| “Amount Realized” for Tax Purposes | $380,000 (The full loan balance, not the home’s value) |
| Phantom Capital Gain | $230,000 ($380,000 Amount Realized – $150,000 Basis) |
| Applying the §121 Exclusion | The homeowner’s $250,000 exclusion completely covers the $230,000 phantom gain. |
| Taxable Gain | $0 |
| Cancellation of Debt Income | $0. Because the loan is non-recourse, the $60,000 difference between the loan balance and the home’s value is forgiven without creating taxable income.37 |
The §121 exclusion is a powerful shield in this scenario. It can often wipe out the phantom gain, and the non-recourse nature of the loan prevents any tax liability on the forgiven debt, allowing the homeowner to walk away with no tax bill despite the foreclosure.
State Law Nuances: How Where You Live Can Change the Game
Federal tax law provides the foundation, but state law can add a significant twist, especially for married couples. The key difference is whether you live in a community property state or a common law state.
The nine community property states are: Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin.14 In these states, when the first spouse dies, the entire value of the home gets a 100% step-up in basis to its current market value.14 This is a massive advantage, allowing the surviving spouse to sell the home immediately with little to no capital gains tax.
In the other 41 common law states, the rules are less generous. When the first spouse dies, only their half (50%) of the property’s value gets a step-up in basis.14 The surviving spouse’s original 50% basis remains unchanged, which can lead to a significant tax bill if they decide to sell.
Reverse Mortgage Pros and Cons
| Pros | Cons |
| Access to Equity: Allows you to tap into your home’s value without selling it, providing cash for retirement.8 | High Upfront Costs: Origination fees, mortgage insurance, and closing costs can be significantly higher than traditional loans.39 |
| No Monthly Payments: Frees up monthly cash flow by eliminating mortgage payments, though you still pay property charges.9 | Growing Loan Balance: The amount you owe increases over time, systematically reducing the equity left for you or your heirs.9 |
| Stay in Your Home: The primary goal is to help seniors “age in place” and remain in their familiar surroundings.8 | Reduces Inheritance: The loan is paid back from the home’s value, which directly shrinks the asset you can pass on to family.17 |
| Non-Recourse Protection: You and your heirs can never owe more than the home is worth, protecting other assets.28 | Strict Borrower Obligations: You must pay property taxes and insurance and maintain the home, or you risk foreclosure.8 |
| Tax-Free Proceeds: The money you receive is a loan, not income, so it is not taxable and doesn’t affect Social Security or Medicare.14 | Complex for Heirs: The process can be confusing and stressful for heirs, who face tight deadlines to resolve the loan. |
Mistakes to Avoid: Common Pitfalls and Their Painful Consequences
- Forgetting Property Charges: The most common reason for default is failing to pay property taxes and homeowners insurance. The consequence is severe: the lender can call the entire loan due and begin foreclosure proceedings.
- Losing Improvement Records: Not keeping receipts and records for every capital improvement (like a new roof or kitchen) means you can’t prove a higher adjusted basis. The consequence is paying significantly more in capital gains tax than you legally owe when you sell.
- Heirs Ignoring Notices: When heirs receive the “Due and Payable Notice,” ignoring it or delaying action is a critical error. The consequence is that the lender will proceed with foreclosure, potentially causing the heirs to lose out on any remaining equity in the home.
- Misunderstanding Spousal Rights: If a younger, non-borrowing spouse is not properly listed as an “eligible non-borrowing spouse” on the loan documents, they may not have the right to remain in the home after the borrowing spouse passes away.40 The consequence could be the forced sale of the home to repay the loan.39
Frequently Asked Questions (FAQs)
Are the funds I get from a reverse mortgage taxable income?
No. The IRS considers the money you receive to be loan proceeds, not income. Therefore, the funds are not taxable and do not need to be reported on your tax return.14
Can I deduct the interest on my reverse mortgage each year?
No. You cannot deduct the interest as it accrues. A deduction can only be taken once the interest is actually paid, which typically happens when the loan is paid off in full.39
Do my heirs have to pay the bank if the loan is more than the house is worth?
No. HECM reverse mortgages are non-recourse loans. This means your heirs will never owe more than the home’s value. FHA mortgage insurance covers any shortfall for the lender.15
Will a reverse mortgage affect my Social Security or Medicare benefits?
No. Since reverse mortgage funds are not considered income, they do not affect your eligibility for Social Security or Medicare, which are not based on financial need.9
Can the bank take my other assets to pay off the loan?
No. For non-recourse HECM loans, the home itself is the only asset that can be used for repayment. Your other investments, savings, or assets are protected from the lender.9
As an heir, do I have to pay capital gains tax on the home’s appreciation during my parent’s life?
No. Due to the “stepped-up basis” rule, the home’s tax basis resets to its fair market value at your parent’s death. This erases all prior appreciation for capital gains tax purposes.
