When Estimated Tax Payments Are Due and How They Work

Estimated payments are quarterly tax bills you send to the IRS yourself, not withheld from a paycheck

If you're self-employed, have investment income, or don't have enough tax withheld from your job, the IRS expects you to send in tax money four times a year instead of waiting until April. These are called estimated tax payments, and they're due on specific dates set by the IRS. Missing a due date can trigger penalties and interest, even if you end up overpaying when you file your full return.

The four due dates fall roughly every three months and are tied to the calendar quarter you're paying for—not the quarter you earned the money. The IRS publishes the exact dates each year because they shift slightly depending on weekends and holidays. If a due date lands on a weekend or federal holiday, you have until the next business day.

Key Takeaways

• Estimated payments are due on April 15, June 15, September 15, and January 15 of the following year, though the exact date shifts if it falls on a weekend or holiday.
• You owe estimated payments if you expect to owe $1,000 or more in taxes after subtracting withholding and credits, though the threshold varies slightly by filing status.
• You can pay online through IRS Direct Pay or the Electronic Federal Tax Payment System (EFTPS), by mail with Form 1040-ES, or through a tax professional.
• Paying late triggers a penalty and interest charge calculated from the due date, even if you overpay overall when you file your return in April.
• If you miss a payment, you can still file your return on time and pay the full amount owed, then request a penalty waiver if you have reasonable cause.

The four due dates and what quarter each one covers

The first estimated payment (for income earned January through March) is due April 15. The second payment (April through May income) is due June 15. The third payment (June through August income) is due September 15. The fourth payment (September through December income) is due January 15 of the following year.

The IRS publishes a full list of due dates each year on its website because the exact day can shift. For example, if April 15 falls on a Saturday, the due date becomes April 17 (the following Monday). If June 15 is a Sunday, it moves to June 17. Federal holidays also push dates forward. Check the IRS website or your tax software for the current year's exact dates rather than relying on the standard calendar dates.

Who has to make estimated payments

You owe estimated taxes if you expect to owe $1,000 or more in federal income tax after subtracting any tax withheld from paychecks and any tax credits you'll claim. The exact threshold is $1,000 for most filers, though it's $500 for married people filing separately. This applies to self-employed people, freelancers, gig workers, investors, retirees withdrawing from retirement accounts, and anyone else with income that isn't subject to withholding.

If you have a job where taxes are withheld but you also have side income, rental income, or investment gains, you may still owe estimated payments on the non-withheld income. You don't have to make estimated payments if your withholding and credits will cover your full tax bill—the IRS only requires them when you're short.

How to calculate what you owe each quarter

The simplest method is to divide your expected annual tax bill by four and pay that amount each quarter. To find your expected tax bill, estimate your total income for the year, subtract deductions, and calculate the tax on that amount using the current year's tax tables or a tax calculator. Then subtract any tax that will be withheld from paychecks or pensions. The remainder is what you owe in estimated payments.

If your income is uneven across quarters—for example, you earn most of your freelance income in the fall—you can use the annualized installment method to pay more in heavy-income quarters and less in light ones. This requires calculating tax on income earned through each quarter separately, which is more complex but can reduce or eliminate penalties if your income is lumpy. Form 2210 walks through this calculation, though most tax software can do it for you.

A common mistake is using last year's tax bill as your estimate. If your income has grown or changed, last year's number will be too low and you'll face penalties. Recalculate each year based on what you actually expect to earn.

How to send in your estimated payment

IRS Direct Pay is the fastest and most direct route. You go to irs.gov, enter your payment amount and due date, and transfer money from your bank account. There's no fee, and the IRS confirms receipt immediately. You can schedule a payment up to 120 days in advance.

EFTPS (Electronic Federal Tax Payment System) is another online option that requires you to enroll first—it takes about a week to activate. Once enrolled, you can make payments anytime and schedule them in advance. EFTPS is often used by tax professionals and businesses making multiple payments.

You can also pay by credit or debit card through a third-party processor, though they charge a fee (usually 1.5 to 2 percent of your payment). Mail is the slowest option: fill out Form 1040-ES, include a check or money order, and mail it to the IRS address listed in the form instructions. The IRS must receive it by the due date, not just have it postmarked by then.

What happens if you miss a due date

The IRS charges a failure-to-pay penalty and interest on any late estimated payment. The penalty is typically 0.5 percent of the unpaid amount per month (or part of a month) that it's late. Interest is calculated daily at a rate set quarterly by the IRS—it's usually between 8 and 10 percent annually. Both penalties and interest accrue from the original due date, not from when you eventually pay.

You don't lose the right to file your return on time if you miss an estimated payment. You can still file on April 15 and pay the full amount owed, including the penalty and interest. However, the penalty will be calculated and added to your bill. If you have reasonable cause—a serious illness, a death in the family, or a genuine mistake—you can request a penalty waiver by filing Form 2210 or Form 2220 with your return or by calling the IRS after you file.

Adjusting payments if your income changes mid-year

If you realize partway through the year that your income will be higher or lower than you estimated, you can adjust your remaining payments. If you're earning more, increase the next payment to catch up. If you're earning less, reduce the next payment to avoid overpaying. You don't have to wait until the end of the year to make this change.

Some people pay the same amount every quarter for simplicity, then settle up when they file their return in April. Others adjust each quarter based on actual income so far. Both approaches work—the key is paying enough by year-end to stay under the $1,000 threshold (or $500 if married filing separately) and avoid penalties.

Frequently Asked Questions

What if I pay estimated taxes but then don't owe anything when I file?

You'll get a refund of the overpayment, just like if you overpaid through withholding. You can claim the refund on your return or request that the IRS apply it to next year's estimated payments. There's no penalty for overpaying.

Can I make estimated payments monthly instead of quarterly?

The IRS only recognizes four due dates per year. You can pay more than once per quarter if you want to spread payments out, but the penalty is calculated based on whether you've paid enough by each official due date. Paying monthly won't reduce a penalty if you're short by the quarterly deadline.

Do I have to make estimated payments if I'm retired and living on Social Security?

Social Security itself isn't subject to estimated payments. However, if you have other income—such as withdrawals from a traditional IRA, rental income, or investment gains—you may owe estimated taxes on that income. Social Security withholding is separate and handled through Form W-4V.

What if I can't afford to pay the full estimated amount by the due date?

Pay what you can by the due date to reduce the penalty. The penalty is calculated on the unpaid balance, so a partial payment is better than no payment. You can pay the rest later and request a penalty waiver if you have reasonable cause, such as a job loss or unexpected expense.

How do I know if I should use the annualized method instead of equal quarterly payments?

Use the annualized method if your income varies significantly by quarter—for example, if you earn most of your income in the fall. It can reduce or eliminate penalties if you pay more in high-income quarters. Your tax software or a tax professional can calculate both methods and show you which saves money.
