Massachusetts Form 1-ES is the Estimated Income Tax Payment Voucher that residents, nonresidents, and part-year residents use to prepay state income tax on earnings not subject to Massachusetts withholding. The Massachusetts Department of Revenue (DOR) requires you to file Form 1-ES if you expect to owe more than $400 in Massachusetts income tax after subtracting withholding and credits, under M.G.L. c. 62B § 13.
Roughly 350,000 Massachusetts taxpayers file estimated payments each year, and DOR data shows that nearly one in five gets hit with an underpayment penalty on Form M-2210 because they miscalculate the safe harbor or miss a quarterly deadline. The 4% surtax on taxable income over the indexed Chapter 62 threshold (often called the “millionaire’s tax”) has only made the math harder since it took effect for tax years beginning on or after January 1, 2023, and the threshold is adjusted yearly under TIR 23-12.
In this guide, you will learn:
- 📋 Who must file Form 1-ES and which income triggers the requirement
- 🧮 How to calculate each quarterly payment using the Estimated Tax Worksheet
- 🖊️ Line-by-line instructions for every box on the voucher
- 💸 How to pay through MassTaxConnect or by mail
- ⚠️ How to dodge the M-2210 penalty using the 80% / 100% safe harbor
What the Form Is and Who Must File It
Form 1-ES is the official quarterly voucher the Massachusetts Department of Revenue uses to collect income tax that is not withheld at the source. The current voucher carries a 2026 revision date and is published in the Form 1-ES instruction booklet on Mass.gov. The state’s flat individual income tax rate is 5% on most income, plus the 4% surtax on the portion of taxable income above the Chapter 62 threshold (which is indexed each year and explained in TIR 23-12).
You must file Form 1-ES if you expect to owe more than $400 in Massachusetts tax after withholding and refundable credits. The rule applies to self-employed workers, gig drivers, freelancers, retirees with pension or dividend income, S-corporation shareholders who receive K-1 distributions, partners in partnerships, landlords with rental income, and anyone with significant capital gains. Part-year residents and nonresidents with Massachusetts-source income also file Form 1-ES when their non-withheld tax tops $400, as confirmed in the Form 1-NR/PY instructions.
Filers who get all their income through W-2 wages and have enough state tax withheld do not file Form 1-ES. If your withholding falls short, you can adjust your Massachusetts Form M-4 instead of sending vouchers. Married couples may file joint estimated payments or separate ones, but joint vouchers must use the spouse listed first on Form 1 to keep DOR’s matching system happy. Trust and estate fiduciaries use Form 2-ES, not Form 1-ES.
The statutory authority sits in M.G.L. c. 62B §§ 13–14, which require declaration and payment of estimated tax. Ignoring the statute triggers the underpayment addition under M.G.L. c. 62C § 32. DOR cross-references each 1-ES payment with your final Form 1 or Form 1-NR/PY to reconcile the year.
Before You Start: Documents and Information You Need
Estimated tax math goes faster when you gather paperwork first. Pull last year’s return, your year-to-date income records, and a clear projection of what the rest of the year will bring. The Estimated Tax Worksheet inside the Form 1-ES booklet walks you through the numbers, but it only works if you have the inputs ready.
Use this pre-filing checklist before you open the voucher:
- Prior-year Massachusetts Form 1 or Form 1-NR/PY, because the 100%-of-prior-year safe harbor depends on line 32 of that return; missing it forces you to use the riskier current-year estimate.
- Social Security number or ITIN for you and your spouse, since DOR rejects vouchers with mismatched SSNs and routes the payment to “unidentified receipts.”
- Current legal name and mailing address that match SSA records, because a name mismatch can stall posting for weeks.
- Year-to-date profit-and-loss statement if self-employed, since net Schedule C-equivalent income drives the 5% Part B calculation.
- Brokerage statements showing interest, dividends, and realized capital gains, because Massachusetts taxes short-term capital gains at 8.5% and long-term gains on collectibles at 12%.
- Pension, annuity, and IRA distribution forecasts, since most retirees do not have Massachusetts withholding on these payments.
- K-1 estimates from any S corporation, partnership, or trust, because pass-through income flows to your personal Form 1 with no withholding.
- Bank routing and account numbers for ACH debit through MassTaxConnect, so you can pay electronically without writing a check.
- Last year’s federal Form 1040 and projected federal AGI, because the 4% surtax piggybacks on Massachusetts taxable income calculations that mirror parts of the federal return.
- A calendar with the four 2026 due dates circled: April 15, 2026, June 15, 2026, September 15, 2026, and January 15, 2027, to avoid the late-payment hit.
If any item is missing, your worksheet will be wrong, and an undercalculation flows straight into a penalty on next April’s Form M-2210. Self-employed filers should also keep mileage logs and expense receipts because they reduce net business income and therefore the estimated tax due.
Where to Get the Form and How to Access It
The official voucher and instructions live on the DOR forms library at mass.gov estimated tax forms. The PDF includes four pre-printed vouchers (one per quarter), the Estimated Tax Worksheet, and a record-of-payments grid. The 2026 revision date is printed in the lower-left corner of each voucher, and you should confirm you are using the current version before mailing anything.
Most filers skip the paper form and pay through MassTaxConnect, DOR’s free online portal. MassTaxConnect lets you pay without an account by choosing “Make a Payment” and selecting “Estimated Payment” as the type. If you create an account, the portal stores your payment history, lets you schedule all four quarters in advance, and sends email confirmations.
Tax software such as TurboTax, H&R Block, and TaxAct can also generate prefilled Form 1-ES vouchers based on last year’s return. Massachusetts public libraries stock paper copies during tax season, and you can call the DOR forms line at (617) 887-6367 to request a booklet by mail. Tax professionals who file through MassTaxConnect for Tax Professionals can submit vouchers on a client’s behalf.
Always download a fresh copy each year. The voucher’s scan line at the bottom encodes the tax year, and using last year’s PDF can route your payment to the wrong period. If DOR posts your money to 2025 instead of 2026, you must file Form ABT to move it.
Step-by-Step: How to Fill Out Form 1-ES Line by Line
Each Form 1-ES voucher has a small footprint, but every box matters. The voucher contains your identifying information, the payment amount, the quarter indicator, and a scan line that DOR’s optical readers use to post the payment. Work through the boxes in the order they appear, and keep a photocopy or scan of every voucher you mail.
Box 1: Your Social Security Number
This box asks for the SSN of the primary taxpayer. Write the nine digits with no dashes if you are typing on the PDF, or with the standard 123-45-6789 format if you are handwriting on paper. Maria Lopez writes 123-45-6789 in Box 1 because that is the SSN printed on her Social Security card. If you have an ITIN instead of an SSN, enter the ITIN in the same box.
A common edge case is a newly married filer who plans to use a spouse’s SSN as the primary on Form 1; in that case, list the same SSN here that will appear first on the joint return. The most common mistake is reversing two digits, which sends your payment to “unidentified receipts” and forces a manual trace that can take 8–12 weeks. A frequent misconception is that DOR can match by name alone; it cannot, because the agency’s posting system is keyed on SSN first.
Box 2: Spouse’s Social Security Number (if filing jointly)
Enter your spouse’s SSN only if you plan to file a joint Massachusetts return and want this estimated payment credited jointly. Format the number the same way as Box 1. Marcus and Janet Reed enter 987-65-4321 for Janet’s SSN because they will file Form 1 jointly in April 2027.
A nuance: if you file separate federal returns but a joint Massachusetts return, you still complete Box 2. The biggest mistake here is leaving Box 2 blank when paying jointly, which causes DOR to credit the entire payment to the primary spouse only; the secondary spouse then shows zero estimated payments on their own account. A misconception is that you can switch from joint to separate vouchers mid-year without consequence — you can, but you must allocate prior joint payments on Schedule E of the final return.
Box 3: Your First Name, Middle Initial, and Last Name
Enter your full legal name exactly as it appears on your Social Security card. Use uppercase letters if handwriting, since the scanner reads block print more reliably. Carlos A. Rivera writes CARLOS A RIVERA across Box 3.
If your last name has a hyphen, suffix, or apostrophe, include it. The most common mistake is using a nickname or a maiden name that no longer matches SSA, which delays processing because DOR’s name-control match fails. A misconception is that the name must match your driver’s license; it must match SSA records, which is not always the same thing.
Box 4: Spouse’s First Name, Middle Initial, and Last Name
Fill in your spouse’s full legal name when paying jointly. The order matters: this name must match the second name on your eventual joint Form 1. Janet M. Reed writes JANET M REED in Box 4.
A nuance: if your spouse changed names during the year, use the name currently on file with SSA, not the prior name. The common mistake is listing the spouse with a different surname than what SSA shows, which breaks the joint match. A misconception is that DOR will “figure it out” — DOR’s automated posting will not, and a human review can add weeks.
Box 5: Mailing Address
Enter the street address, apartment number, city, state, and ZIP code where DOR should send any correspondence about this payment. Aisha Bennett writes 145 ELM ST APT 3B, WORCESTER MA 01608 in Box 5.
A common edge case is a P.O. Box: that is allowed and often preferred for filers who travel or move frequently. The most common mistake is using an old address from a prior return, which means refund checks or notices may be returned to DOR as undeliverable. A misconception is that the address must match your federal return; it does not, but consistency reduces confusion.
Box 6: Voucher Number (Quarter Indicator)
Each of the four pre-printed vouchers in the Form 1-ES booklet shows a different number — 1, 2, 3, or 4 — corresponding to the four quarterly due dates. Voucher 1 is due April 15, 2026; Voucher 2 is due June 15, 2026; Voucher 3 is due September 15, 2026; and Voucher 4 is due January 15, 2027. Maria sends Voucher 1 marked “1 of 4” before April 15.
A nuance: if you start earning self-employment income mid-year, your first voucher may be Voucher 2 or 3, not Voucher 1. The common mistake is mailing Voucher 2 by April 15 thinking the quarter labels are interchangeable, which causes DOR to post the payment to the wrong quarter and may trigger a Q1 underpayment penalty even though you paid early. A misconception is that the quarters are equal three-month periods; they are not — Q2 covers only April–May, Q3 covers June–August, and Q4 covers September–December.
Box 7: Amount of This Installment
This box is the dollar amount you are paying for the quarter. Enter whole dollars only, no cents, and do not use commas. Carlos writes 1850 in Box 7 because his Estimated Tax Worksheet shows annual liability of $7,400 split into four equal installments.
A nuance: you can pay more in early quarters and less later, or vice versa, as long as the cumulative amount paid by each due date meets the safe harbor. The most common mistake is rounding to the nearest hundred and underpaying — DOR’s penalty is based on actual installment shortfalls, not rounded approximations. A misconception is that paying the annual total once in April satisfies the obligation; it does, but only if you pay enough by April 15 to cover the full annual safe harbor, which is rarely worth the cash-flow hit.
Box 8: Estimated Tax Worksheet — Line 1 (Estimated Massachusetts Income)
Although the worksheet sits separately from the voucher, you must complete it before filling Box 7. Line 1 asks for your projected total Massachusetts gross income for the year, including wages, self-employment net profit, interest, dividends, capital gains, pensions, rental income, and pass-through income. Marcus projects $112,000 in total 2026 Massachusetts income and writes that on Line 1.
A nuance: nonresidents enter only Massachusetts-source income, not worldwide income. The common mistake is forgetting to include Roth conversion income or one-time capital gains, which understates the estimate. A misconception is that you can ignore tax-exempt interest; for the surtax calculation, certain tax preference items add back in.
Box 9: Estimated Tax Worksheet — Line 5 (5% Tax)
Multiply your Part B taxable income by 5% (0.05) and enter the result. This is the bedrock Massachusetts rate for wages, self-employment, interest, dividends, and most retirement income. Aisha multiplies $48,000 × 0.05 = $2,400 and writes it on Line 5.
A nuance: certain interest from Massachusetts banks gets a $100 (single) or $200 (joint) exemption before the 5% applies. The common mistake is applying 5% to gross income instead of taxable income (after exemptions and deductions), which overstates the estimate. A misconception is that the rate has dropped recently; the 5% rate has been stable for several years and is set in M.G.L. c. 62 § 4.
Box 10: Estimated Tax Worksheet — 4% Surtax Line
Add the 4% surtax on the portion of taxable income above the indexed Chapter 62 threshold. The threshold is adjusted annually; check the current Form 1-ES instructions for the 2026 amount. A high-earning S-corp shareholder with $1.3 million in taxable income owes 4% on income above the threshold and enters that surtax amount here.
A nuance: married couples filing jointly use a single threshold, not a doubled one, which surprises many filers. The common mistake is applying the surtax to all taxable income instead of only the slice above the threshold, which dramatically overstates the estimate. A misconception is that the surtax replaces the 5% rate; it stacks on top, so income above the threshold effectively pays 9% combined, as explained in TIR 23-12.
Box 11: Estimated Tax Worksheet — Credits and Withholding
Subtract expected Massachusetts withholding (from W-2s, 1099-Rs, etc.) and refundable credits (such as the Earned Income Credit and Senior Circuit Breaker) from your projected tax. Janet expects $4,200 of pension withholding and subtracts it from her $6,800 projected tax to get $2,600 of estimated tax due.
A nuance: nonrefundable credits like the limited-income credit also reduce the estimate, but only up to the tax owed. The common mistake is forgetting to subtract spouse’s withholding on a joint voucher, which overstates the estimate and ties up cash. A misconception is that prior-year overpayments applied forward count as withholding; they count as the first installment, applied automatically by DOR.
Box 12: Estimated Tax Worksheet — Installment Amount
Divide the net estimated tax by four, or use the annualized income method if your income is uneven. Carlos divides $7,400 by 4 to get $1,850 per voucher. Enter this number on the worksheet and copy it to Box 7 of each voucher.
A nuance: the annualized income method (Schedule M-2210, Part 4) lets seasonal earners pay less early in the year and more later. The common mistake is splitting the annual amount into four equal pieces when income is heavily back-loaded, which front-loads cash unnecessarily. A misconception is that the four installments must be equal; they do not, as long as cumulative payments hit the safe harbor at each due date.
Signature and Date
Form 1-ES does not require a signature on the voucher itself, which surprises new filers. The implied authorization happens when you submit the payment. Date the voucher with the date you mail or transmit it, not the due date.
A nuance: if a paid preparer fills out the voucher, no preparer signature line exists, but the preparer should keep a copy for their records. The common mistake is assuming the voucher is invalid without a signature and delaying the mailing, which causes a late payment. A misconception is that the absence of a signature means the payment is anonymous; the SSN ties it to you.

How to File the Completed Form
Massachusetts gives you four ways to deliver a Form 1-ES payment, and DOR strongly prefers electronic filing through MassTaxConnect. Each channel has different processing times, fees, and proof-of-payment options.
MassTaxConnect (online ACH debit). Go to mtc.dor.state.ma.us, choose “Make a Payment,” select “Estimated Payment” and tax year 2026. There is no fee for ACH debit from a checking or savings account. Funds typically post within 1–2 business days, and the portal emails a confirmation number that serves as proof of filing. Save the confirmation as a PDF.
MassTaxConnect (credit or debit card). The same portal accepts cards through a third-party processor that charges roughly 2.35% of the payment as a convenience fee. Posting takes 1–2 business days, and the processor issues a receipt that doubles as proof. Card payments suit filers who want airline miles or who lack a checking account.
Mail with paper voucher. Detach the correct quarter’s voucher from the Form 1-ES booklet, enclose a check or money order payable to “Commonwealth of Massachusetts,” write your SSN and “2026 Form 1-ES” on the check, and mail to Massachusetts Department of Revenue, P.O. Box 419540, Boston, MA 02241-9540. Use certified mail with return receipt as proof. Posting can take 2–3 weeks during peak season.
Tax professional via bulk filing. Enrolled agents and CPAs can submit vouchers on a client’s behalf through MassTaxConnect for Tax Professionals. The professional retains a digital confirmation that protects both parties.
Whichever channel you use, the postmark or transmission date controls. A voucher mailed April 15 with a USPS postmark is timely even if DOR posts it April 22. Save proof for at least three years because the look-back window for M-2210 penalty disputes runs that long.
What Happens After You File
Once DOR receives your payment, the agency posts it to your taxpayer account within a few business days for electronic payments and within 2–3 weeks for mailed checks. You can verify posting by logging into MassTaxConnect and viewing the “Payments” tab under your individual income tax account. The portal shows the date received, the quarter applied, and the running annual total.
DOR does not send a paper acknowledgement for each voucher, so the MassTaxConnect record is your trail. If a payment does not appear within three weeks, call DOR at (617) 887-6367 with your SSN and the check or confirmation number. Misposted payments usually get traced and corrected within 30 days, but only if you initiate the inquiry.
When you file your final Form 1 or Form 1-NR/PY in April 2027, you report the total of your four 2026 Form 1-ES payments on the “Estimated tax payments” line. DOR’s automated reconciliation cross-checks your reported total against its records; any mismatch generates a notice. If your withholding plus estimated payments exceed your final liability, DOR refunds the excess; if not, you pay the balance and possibly an M-2210 penalty.
Filers who realize mid-year that they overpaid an installment cannot get a quarterly refund; the overpayment rolls forward and is reconciled on the final return. Filers who realize they underpaid can catch up on the next voucher to minimize the penalty, since the penalty is calculated quarter by quarter.
Mistakes to Avoid When Filling Out the Form
Form 1-ES looks simple, but small errors create big posting problems. The following ten mistakes drive the bulk of penalty notices and traced-payment cases that DOR handles each year.
- Reversing SSN digits in Box 1, which sends the payment to unidentified receipts and delays posting by 8–12 weeks.
- Mailing Voucher 2 by April 15 instead of Voucher 1, which posts the payment to Q2 and triggers a Q1 underpayment penalty.
- Forgetting to enter the spouse’s SSN on a joint voucher, which credits the entire payment to one spouse.
- Using last year’s PDF, which contains a prior-year scan line and routes the money to the wrong tax year.
- Writing dollars and cents in Box 7 when the box accepts whole dollars only, which can cause OCR misreads.
- Failing to include the 4% surtax on income above the indexed Chapter 62 threshold, which understates the estimate and triggers a penalty.
- Treating quarterly periods as equal three-month chunks rather than the actual 4-2-3-3 month split the IRS and DOR use.
- Applying the 5% rate to gross income instead of Massachusetts taxable income, which overstates the estimate.
- Forgetting to subtract pension or 1099-R withholding from the estimate, which doubles up on the same dollars.
- Mailing the voucher to the wrong P.O. Box (DOR uses different boxes for returns, payments, and amended filings), which delays posting by weeks.
Each mistake has a direct cash consequence: an underpayment triggers an M-2210 penalty calculated as the federal short-term rate plus 4%, compounded daily, on the unpaid quarterly balance.
Do’s and Don’ts
A short list of habits keeps your Form 1-ES filings clean from the first quarter to the fourth.
Do’s:
- Do download a fresh Form 1-ES PDF each year, because the scan line encodes the tax year and prior-year vouchers misroute payments.
- Do pay through MassTaxConnect, because electronic posting is faster and gives you an instant confirmation number.
- Do calculate the safe harbor both ways (80% of current year and 100% of prior year), because the lower of the two is your target.
- Do keep a payment log with date, amount, and confirmation number for all four quarters, because the log is your defense in a penalty dispute.
- Do recalculate mid-year if your income changes materially, because the annualized income method on Schedule M-2210 can reduce or eliminate a penalty.
- Do include the 4% surtax in your estimate if your income is near or above the Chapter 62 threshold, because DOR enforces the surtax through estimated tax just like the base 5%.
Don’ts:
- Don’t write your SSN in only the check memo line and skip Box 1, because DOR’s posting system reads the voucher first.
- Don’t assume W-2 withholding alone covers a side hustle, because Massachusetts taxes 1099 income at the same 5% with no withholding cushion.
- Don’t postdate a check, because DOR may deposit it immediately and a bounced check creates a $30 returned-payment fee plus the underpayment penalty.
- Don’t combine two quarters on one voucher, because DOR posts the entire amount to the quarter on the voucher, leaving the other quarter unpaid.
- Don’t ignore a DOR notice, because penalty and interest accrue while the issue sits, and the Form ABT abatement window is limited.
- Don’t forget that part-year and nonresident filers still owe estimated tax on Massachusetts-source income, because residency does not waive the $400 trigger.
Pros and Cons of Filing on Your Own vs. With Help
Many Massachusetts filers handle Form 1-ES themselves, but a CPA or enrolled agent can be worth the fee for complex situations. Weigh the trade-offs before deciding.
Pros of filing on your own:
- Cost savings, because DIY filing is free aside from any card processing fee.
- Speed, because you can pay through MassTaxConnect in under five minutes once your worksheet is done.
- Direct control over timing, because you choose the exact debit date and amount.
- Learning curve payoff, because understanding your own tax picture helps with year-round planning.
- Privacy, because you do not share financial details with a third party.
Cons of filing on your own:
- Higher risk of miscalculating the safe harbor, especially for filers near the surtax threshold.
- No professional defense if DOR sends an underpayment notice or audit letter.
- Time cost of tracking four due dates and recalculating after life events.
- Easier to forget the annualized income method, which can save penalty dollars for seasonal earners.
- Greater chance of using the wrong voucher number or mailing address.
A self-employed filer with steady income usually does fine alone; an S-corp shareholder near the surtax threshold or a part-year resident with multi-state issues often benefits from a CPA who can run the numbers and file through MassTaxConnect for Tax Professionals.
Form 1-ES vs. Federal Form 1040-ES
| Topic | Massachusetts vs. Federal |
|---|---|
| Tax base | Massachusetts uses Part A/B/C income from Form 1; federal uses AGI from Form 1040-ES |
| Rate | Massachusetts is flat 5% plus 4% surtax above threshold; federal is graduated through 37% |
| Trigger | Massachusetts requires filing if you owe more than $400; federal requires filing if you owe more than $1,000 |
| Safe harbor | Massachusetts uses 80% of current year or 100% of prior year; federal uses 90%/100% (110% for high-AGI) |
| Portal | MassTaxConnect for state; IRS Direct Pay or EFTPS for federal |
| Due dates | Both follow the same 4-15, 6-15, 9-15, 1-15 calendar |
FAQs
Do I need to file Form 1-ES if my only income is W-2 wages?
No. Form 1-ES is for income without Massachusetts withholding; if your W-2 withholding covers your liability, adjust Form M-4 instead.
What is the threshold for filing Form 1-ES?
Yes, you must file when you expect to owe more than $400 in Massachusetts tax after withholding and refundable credits, per M.G.L. c. 62B § 13.
Can I pay all four quarters at once in April?
Yes. DOR accepts a single lump-sum payment covering all four installments through MassTaxConnect, but you lose the cash-flow benefit of spreading payments.
Do I write my maiden name or married name in Box 3?
Yes, write whichever name currently matches your Social Security Administration record, because DOR’s matching system keys on SSA name controls, not driver’s licenses.
Should I include the 4% surtax in my estimate?
Yes. TIR 23-12 requires the surtax in estimated tax calculations whenever projected taxable income exceeds the indexed Chapter 62 threshold.
Do I enter dollars and cents in Box 7?
No. Box 7 accepts whole dollars only; round to the nearest dollar to keep DOR’s OCR scanners from misreading the entry.
Can I switch from joint to separate vouchers mid-year?
Yes, but you must allocate prior joint payments between spouses on Schedule E of the final return, which adds paperwork.
Do part-year residents file Form 1-ES?
Yes, part-year and nonresidents file Form 1-ES on their Massachusetts-source income when projected non-withheld tax exceeds $400.
Is there a penalty for paying late?
Yes. Form M-2210 calculates the addition at the federal short-term rate plus 4%, compounded daily, on the unpaid quarterly balance.
Can I use last year’s prior-year overpayment as my first installment?
Yes, applying a prior-year refund forward counts as a Q1 estimated payment posted on April 15 of the new year.
Do I sign Form 1-ES?
No. The voucher has no signature line; submitting the payment is the implied authorization, and DOR does not require a wet signature.
What if I miss the April 15 deadline?
Yes, pay as soon as possible because the M-2210 penalty is calculated daily, and catching up on the next quarter does not erase the Q1 shortfall.
Can I cancel a scheduled MassTaxConnect payment?
Yes, log into MassTaxConnect at least two business days before the scheduled debit date and select “Cancel” on the pending payment.
Does Form 1-ES cover the Paid Family and Medical Leave contribution?
No. Form 1-ES covers Chapter 62 income tax only; PFML contributions are reported separately by employers under M.G.L. c. 175M.
