Do I Have to Make Estimated Tax Payments? Safe Harbors and Deadlines

You have to make estimated tax payments if you expect to owe at least $1,000 in federal tax for the year after subtracting your withholding and refundable credits.¹ The rule doesn’t care what kind of income creates the balance; it only cares whether enough tax is being paid in throughout the year. So a salaried employee with a big side gig can owe estimated tax while a retiree with generous pension withholding may not.

Who Usually Has to Pay

The requirement most commonly hits people whose income arrives without tax already taken out:

Sole proprietors, freelancers, independent contractors, and gig workers.
Investors with significant dividends, interest, or capital gains outside retirement accounts.
Partners in partnerships and S corporation shareholders, whose share of business profit passes through to their personal return with no withholding.
Landlords whose net rental income creates a balance beyond any wage withholding.
Retirees whose pension or Social Security withholding falls short of their actual tax.

Pass-through business income is a particular trap. If you’re a partner or S corporation shareholder, the business itself doesn’t pay federal income tax, so your share of the profit lands on your 1040 with nothing withheld against it. Without quarterly payments, the balance at filing time can be large.²

When You Don’t Have To

Three situations get you out of the requirement.

First, if your total tax minus withholding and credits will come in under $1,000, you owe no estimated payments at all.²

Second, you’re fully exempt for the year if you had zero tax liability the prior year. That means the “total tax” line on your 2025 Form 1040 was zero, or you weren’t required to file. Two conditions apply: the prior year had to be a full 12-month tax year, and you had to be a U.S. citizen or resident for the whole year.³ This often helps new graduates whose first working year produced little income, or someone with a gap year between careers.

Third, if you draw a W-2 salary alongside other income, you can raise your paycheck withholding instead of making quarterly payments. Submit a new Form W-4 to your employer asking for extra withholding, and the additional tax pulled from each paycheck can absorb your investment, freelance, or rental income.¹ The IRS Tax Withholding Estimator at irs.gov will figure the right amount and generate a pre-filled W-4.⁴

Withholding has a quiet advantage over quarterly payments. It’s treated as paid evenly across the year even when your employer pulls the extra amount from only a few paychecks late in December. Estimated payments, in contrast, must be timely for each quarter, and a shortfall in one quarter isn’t erased by an overpayment in another. For people who realize mid-year that they’ll owe, a W-4 change is often the cleanest fix.

Safe Harbors That Protect You From Penalties

Even if you owe $1,000 or more, you avoid the underpayment penalty by meeting any one of these safe harbors:²

You pay at least 90% of the tax you actually owe for the current year through withholding and estimated payments combined.
You pay at least 100% of the total tax shown on your prior-year return.
Your remaining balance at filing is under $1,000.

The prior-year option is the one most people rely on, because it doesn’t require predicting the current year accurately. Match last year’s total tax and you’re covered even if this year’s income jumps sharply. One catch for higher earners: if your prior-year adjusted gross income exceeded $150,000 ($75,000 if married filing separately), the prior-year safe harbor climbs from 100% to 110%. Each quarterly installment is 25% of whichever safe harbor amount you’re targeting.⁵

Figuring Out Whether You’ll Owe $1,000

To decide whether the requirement applies, start with your prior-year return if your income is reasonably stable. Estimate this year’s total income, subtract deductions, apply the tax rates, add self-employment tax if it applies, then subtract expected withholding and credits. Form 1040-ES contains a worksheet that walks through each step.⁶

If the remaining balance comes in at $1,000 or more and no safe harbor covers you, divide by four to get each quarterly payment.¹ The first estimate isn’t binding. If income runs higher or lower than you expected, redo the worksheet and adjust the next payment.

2026 Deadlines and How to Pay

The four payment periods are not equal in length, which trips people up on the second deadline in particular:⁷

1st quarter (January 1 – March 31): April 15, 2026
2nd quarter (April 1 – May 31): June 15, 2026
3rd quarter (June 1 – August 31): September 15, 2026
4th quarter (September 1 – December 31): January 15, 2027

You can skip the January 15 payment if you file your 2026 return and pay the full remaining balance by February 1, 2027.⁶

Payment options include IRS Direct Pay (free bank transfer, no registration), EFTPS (free but requires enrollment, so set it up before your first deadline), credit or debit card through a third-party processor that charges a fee, and check or money order with the Form 1040-ES voucher.⁷ You can also apply a prior-year refund toward this year’s estimated tax by electing on your return to credit the overpayment forward rather than receive it.⁸

What Happens If You Skip Them

The underpayment penalty works more like interest than a fine. The IRS charges the underpayment rate on whatever should have been paid for the period it was late, and the rate adjusts quarterly based on the federal short-term rate plus three points. For the first quarter of 2026, the rate is 7% annually, compounded daily.⁹⁵

The penalty is calculated separately for each quarter. Underpay in Q1 and cover it with an extra-large Q3 payment, and you still owe interest for the months Q1 was short.¹⁰ One consequence surprises people: you can owe an underpayment penalty even when you’re due a refund for the year overall, because the IRS charges interest for the earlier quarters that ran short.²

Two Boundaries Worth Knowing

If at least two-thirds of your gross income comes from farming or fishing, you follow a different schedule entirely: a single estimated payment by January 15 of the following year, which itself becomes optional if you file your 2026 return and pay in full by March 1, 2027.¹¹

And federal estimated payments are only half the picture in most of the country. Most states with an income tax impose their own estimated payment requirements, and the dollar thresholds, safe harbor percentages, and deadlines don’t always match the federal rules. Check your state’s department of revenue for what applies to you.
