Federal estimated tax payments for 2026 are due on four dates: April 15, 2026, June 15, 2026, September 15, 2026, and January 15, 2027. These quarterly payments cover income tax on earnings that don’t have enough withheld at the source, including self-employment income, investment returns, rental profits, and certain retirement distributions. If you’re a salaried employee with side income, you may need to make them too.
The Four 2026 Deadlines
The IRS divides the year into four payment periods that don’t match calendar quarters. Each deadline covers income earned in a specific window:
- April 15, 2026 — for income earned January 1 through March 31
- June 15, 2026 — for income earned April 1 through May 31
- September 15, 2026 — for income earned June 1 through August 31
- January 15, 2027 — for income earned September 1 through December 31
When a due date lands on a weekend or federal holiday, the payment is on time if you make it the next business day.1Internal Revenue Service. Estimated Tax All four 2026 dates fall on weekdays, so no adjustments apply.2Internal Revenue Service. Form 1040-ES – Estimated Tax for Individuals
You can skip the January 15, 2027 payment if you file your 2026 return by February 1, 2027 and pay the full balance with it.2Internal Revenue Service. Form 1040-ES – Estimated Tax for Individuals That option works well if you can close your books early.
Who Actually Has to Pay
You need to make estimated payments if you expect to owe $1,000 or more in federal tax for 2026 after subtracting withholding and refundable credits.3Office of the Law Revision Counsel. 26 USC 6654 – Failure by Individual to Pay Estimated Income Tax That $1,000 covers income tax and self-employment tax combined, which is why freelancers cross the threshold quickly.
The situations that most often trigger the requirement are self-employment (freelancers, independent contractors, sole proprietors, gig workers), investment income that generates significant tax, net rental profits, and W-2 wages where paycheck withholding doesn’t cover taxes on other income.
One exception: if you had zero tax liability for the prior year, were a U.S. citizen or resident for the whole year, and that prior year covered 12 months, you don’t owe estimated tax for 2026 no matter how much you earn.4Internal Revenue Service. Estimated Taxes
How Much to Pay: The Safe Harbor Rules
You avoid an underpayment penalty if your total withholding and estimated payments for the year hit the lesser of two thresholds:
- 90% of your 2026 tax, or
- 100% of your 2025 tax (as long as that return covered a full 12 months)
These are the “safe harbor” figures set by statute.3Office of the Law Revision Counsel. 26 USC 6654 – Failure by Individual to Pay Estimated Income Tax Hitting either one protects you from the penalty even if you still owe a balance at filing time.
A stricter rule kicks in if your 2025 adjusted gross income was over $150,000 ($75,000 if married filing separately). At that level, the prior-year safe harbor becomes 110% of your 2025 tax rather than 100%.3Office of the Law Revision Counsel. 26 USC 6654 – Failure by Individual to Pay Estimated Income Tax The 90% current-year test doesn’t change.
Most people use the prior-year path because it’s predictable. Take last year’s total tax, divide by four, send that each quarter. If your income jumps in 2026, you might owe a balance at filing time, but not a penalty.
Figuring Out Your Payment
Form 1040-ES includes a worksheet that walks through expected income, deductions, credits, and other taxes to produce an annual estimate, then splits it into four equal installments.2Internal Revenue Service. Form 1040-ES – Estimated Tax for Individuals
Don’t Forget Self-Employment Tax
If you’re self-employed, your estimated payments have to cover both income tax and self-employment tax, which is the freelancer equivalent of the Social Security and Medicare taxes an employer would normally withhold. For 2026, you calculate it on 92.35% of your net self-employment earnings: 12.4% for Social Security (on income up to $184,500) plus 2.9% for Medicare.2Internal Revenue Service. Form 1040-ES – Estimated Tax for Individuals You can deduct half of your self-employment tax when figuring adjusted gross income, which lowers your income tax. Form 1040-ES has a separate worksheet for this.
First-time freelancers often miss this. They estimate income tax, pay quarterly based on that, and get hit at filing time with roughly 15% more in self-employment tax. Build it in from the start.
If Your Income Is Uneven
Equal quarterly installments don’t fit every business. If most of your income arrives in the fall, you’d overpay early and strain cash flow. The annualized income installment method lets each payment reflect what you actually earned through the end of that period, rather than one-quarter of an annual estimate.5Internal Revenue Service. Instructions for Form 2210 (2025) The trade-off is filing Schedule AI of Form 2210 with your return and using the method for all four periods if you use it for any. For most people, the prior-year safe harbor gets you to the same result with less paperwork.
Using W-4 Withholding Instead
If you have a regular paycheck, you can often skip separate estimated payments by increasing withholding on Form W-4. Step 4(a) lets you enter non-wage income so your employer withholds enough to cover it. If you’d rather not share that with your employer, Step 4(c) lets you request a flat extra dollar amount per paycheck.6Internal Revenue Service. Form W-4 – Employees Withholding Certificate
The advantage: withholding from wages counts as paid evenly through the year regardless of when it actually comes out of your paycheck, so the quarterly deadlines effectively disappear.7Internal Revenue Service. Pay As You Go, So You Wont Owe: A Guide to Withholding, Estimated Taxes and Ways to Avoid the Estimated Tax Penalty This works especially well if your side income is steady, such as rental or dividend income.
How to Send the Payment
The IRS accepts estimated payments several ways.
IRS Direct Pay
Direct Pay moves money from a checking or savings account to the IRS at no cost. You can schedule payments up to 365 days ahead and make up to five in any 24-hour window.8Internal Revenue Service. Direct Pay Help The IRS2Go mobile app connects to it as well.9Internal Revenue Service. IRS Payment Options For most individuals, this is the easiest free option.
EFTPS
The Electronic Federal Tax Payment System requires enrollment, but once you’re in you can schedule payments up to 365 days ahead and pull 15 months of history.10Internal Revenue Service. EFTPS: The Electronic Federal Tax Payment System Business owners who pay frequently often prefer it.
Credit Card, Debit Card, or Digital Wallet
You can pay through IRS-authorized processors, but with fees. Credit card processing runs roughly 1.75% to 1.85% of the payment. Debit card fees are flat, around $2.10 to $2.15 per transaction.11Internal Revenue Service. Pay Your Taxes by Debit or Credit Card or Digital Wallet A $5,000 payment on a credit card would cost about $88 to $93 in fees, so this route rarely pays off unless the card rewards clear that hurdle.
Check or Money Order
You can mail a payment with the voucher in Form 1040-ES. Make the check payable to “United States Treasury” and write “2026 Form 1040-ES” and your Social Security number on it.2Internal Revenue Service. Form 1040-ES – Estimated Tax for Individuals Mail early: the IRS uses the received date for mailed estimated payments.
Farmers and Fishermen
If at least two-thirds of your gross income comes from farming or fishing, in either the current or prior year, you get a simpler schedule.12Internal Revenue Service. Farming and Fishing Income You can either make a single estimated payment for the full year by January 15, 2027, or skip estimated payments entirely by filing your 2026 return and paying the balance by March 1, 2027. The two-thirds test can be met in either the current or preceding year.13Internal Revenue Service. Topic No. 416, Farming and Fishing Income
What Happens If You Miss a Deadline
Missing a quarterly date or paying too little triggers an underpayment penalty. The IRS computes it separately for each period, based on the gap between what you should have paid and what you actually paid by the due date.14Internal Revenue Service. Underpayment of Estimated Tax by Individuals, Estates, and Trusts
The rate equals the federal short-term interest rate plus three percentage points and compounds daily. The IRS resets it each quarter. For the first quarter of 2026, the underpayment rate for individuals is 7%.15Internal Revenue Service. Interest Rates Remain the Same for the First Quarter of 2026 Later 2026 rates are posted on the IRS quarterly interest rates page as they’re set.16Internal Revenue Service. Quarterly Interest Rates
A single late payment isn’t ruinous, but the charge compounds and adds up across multiple missed quarters. It’s calculated automatically on Form 2210 when you file. In limited situations (a casualty, disaster, or certain retirement or disability circumstances), the IRS can waive part or all of the penalty on request through Form 2210.17Internal Revenue Service. Instructions for Form 2210
State Payments Are Separate
Most states with an income tax also require estimated payments, often on a schedule that mirrors the federal one. The dollar threshold that triggers the requirement varies, typically somewhere between $100 and $1,000 in expected tax. If you earn income in a state where you don’t live, that state may want its own estimated payments. Check with your state’s department of revenue for the exact threshold and any date differences.
