Federal income tax payments for the 2025 tax year are due by Wednesday, April 15, 2026. That single date is when your tax return and any money you owe must reach the IRS. If you’re self-employed or have other income that isn’t subject to withholding, you also have quarterly estimated tax deadlines throughout the year.
The April 15 Deadline
April 15 is the annual deadline for both filing your federal tax return and paying whatever you owe. These two obligations share the same due date, and missing either one triggers separate penalties. When April 15 falls on a weekend or a federal holiday, the deadline shifts to the next business day, but for the 2025 tax year (filed in 2026), April 15 lands on a Wednesday with no adjustment needed.
If you can’t finish your return in time, you can request a six-month filing extension, which pushes your paperwork deadline to October 15. But the extension only covers your filing. It does not extend your payment deadline. You still owe any taxes by April 15, and interest and penalties start accumulating on unpaid balances after that date, even if you have an approved extension on file.
Estimated Tax Payment Dates
If you earn income that doesn’t have taxes automatically withheld, such as freelance earnings, rental income, investment gains, or business profits, you’re generally expected to pay taxes in quarterly installments rather than waiting until April. These are called estimated tax payments, and the IRS sets four deadlines each year.
For the 2026 tax year, the quarterly estimated tax deadlines are:
- 1st Quarter: April 15, 2026
- 2nd Quarter: June 15, 2026
- 3rd Quarter: September 15, 2026
- 4th Quarter: January 15, 2027
Notice the quarters aren’t evenly spaced. The gap between the first and second payments is only two months, while the gap between the third and fourth is four months. Many self-employed taxpayers miss the June deadline because they assume three-month intervals. Mark all four dates early in the year.
You can make estimated payments through IRS Direct Pay, the Electronic Federal Tax Payment System (EFTPS), or by mailing a check with a payment voucher (Form 1040-ES). If you underpay during the year, you may face an underpayment penalty when you file your annual return.
What Happens If You Pay Late
The IRS charges two separate penalties for missing the April deadline: one for filing late and one for paying late. The failure-to-pay penalty is 0.5% of your unpaid tax balance for each month (or partial month) it remains outstanding. That adds up: if you owe $5,000 and pay three months late, you’d face roughly $75 in penalties alone, plus interest on both the tax and the penalties.
The penalty caps at 25% of your unpaid balance, so it won’t grow indefinitely. And if you file your return on time and set up an IRS-approved payment plan, the monthly rate drops to 0.25%. On the other hand, if you ignore IRS collection notices, the rate jumps to 1% per month after the IRS sends a notice of intent to levy (seize your assets).
Interest on unpaid taxes compounds daily at a rate the IRS sets each quarter, tied to the federal short-term rate plus 3 percentage points. Unlike the penalty, interest has no cap and continues until your balance hits zero.
How to Pay
The IRS accepts several payment methods, and the fastest options are electronic. IRS Direct Pay lets you transfer money directly from a checking or savings account at no cost. EFTPS works similarly but requires a separate enrollment step, which takes about a week. You can also pay by debit or credit card through IRS-approved third-party processors, though those charge processing fees (a flat fee for debit cards and a percentage-based fee for credit cards).
If you can’t pay your full balance by April 15, filing your return on time is still important. The failure-to-file penalty is significantly steeper than the failure-to-pay penalty. Filing on time and paying what you can minimizes your total cost. You can then apply for an installment agreement with the IRS to pay the rest over time, which also reduces the monthly penalty rate.
Extensions for Military and Disaster Areas
Military members stationed abroad or serving in a combat zone get automatic extensions for both filing and paying federal taxes. The length of the extension depends on the specific circumstances, but it generally covers the time spent in the combat zone plus at least 180 days after leaving.
Taxpayers affected by federally declared disasters also receive extended deadlines. The IRS announces these extensions on a case-by-case basis, postponing filing and payment due dates for affected areas. If a disaster hits your region, check the IRS disaster relief page to see whether your deadlines have shifted.
State Tax Deadlines
Most states with an income tax set their filing and payment deadlines to match the federal April 15 date, but not all do. A few states use different deadlines, and state estimated tax schedules can also vary. Check your state’s tax agency website for exact dates, since paying your federal taxes on time doesn’t automatically mean you’ve met your state obligation.
