When the IRS Expects Your Tax Payment and What Happens If You Miss the Date

By Tanika Patel

The IRS has set payment deadlines, and they differ depending on how you file and what you owe

The main federal tax deadline is April 15 of the year following the tax year you're reporting. That date applies whether you owe money, expect a refund, or break even. If April 15 falls on a weekend or federal holiday, the deadline moves to the next business day. For the 2024 tax year, April 15, 2025 is the deadline.

If you owe taxes, that same April 15 date is when payment is due. The IRS does not give you extra time to pay after you file. If you file on April 10 and owe $3,000, that $3,000 is due April 15, not 30 days after you file. Paying late triggers penalties and interest that compound daily.

If you cannot pay by April 15, you have options to delay or break the payment into pieces—but you must act before the deadline, not after. Waiting until May to ask for a payment plan costs you more in penalties than asking in April.

Key Takeaways

  • Federal income tax is due April 15 each year, whether you file electronically or by mail, and the date does not change based on when you file your return.
  • If you owe and cannot pay in full, you can request a short-term extension (120 days) or a long-term payment plan through the IRS before April 15 to reduce penalties.
  • Penalties and interest begin accruing the day after the deadline if you owe and do not pay, even if you filed on time.
  • Estimated quarterly taxes are due on June 15, September 15, December 15, and April 15 if you are self-employed or have income not subject to withholding.
  • The IRS accepts payments online, by phone, by mail, or through a tax professional, and you can set up automatic payments from your bank account.

How the April 15 deadline works if you file early or late

Filing your return and paying your tax are two separate deadlines that happen on the same day. You can file your return on January 15, but if you owe money, that money is still due April 15. Filing early does not buy you extra time to pay.

If you file after April 15 without requesting an extension beforehand, you owe a failure-to-file penalty on top of the tax itself. If you owe and do not pay by April 15, you owe a failure-to-pay penalty in addition to the failure-to-file penalty. Both penalties compound the longer you wait.

If you request a filing extension before April 15, you get until October 15 to submit your return—but your tax payment is still due April 15. An extension to file is not an extension to pay. Many people misunderstand this and end up owing penalties because they thought the October date applied to payment.

Estimated quarterly tax payments for self-employed people and contractors

If you are self-employed, a contractor, or have income that is not subject to withholding (like rental income or investment income), you may owe estimated quarterly taxes instead of one lump sum on April 15. These are due on:

  • June 15 (for income earned January through May)
  • September 15 (for income earned June through August)
  • December 15 (for income earned September through November)
  • April 15 of the following year (for income earned December through the end of the year)

If you miss a quarterly deadline, penalties begin accruing immediately. The IRS calculates estimated tax based on your prior year's income or your current year's projected income. If you underestimate and owe a large amount on April 15, you can still request a payment plan, but penalties will have already started.

What happens if you cannot pay by April 15

Paying late costs you money in two forms: a failure-to-pay penalty and interest. The failure-to-pay penalty is typically 0.5% of the unpaid tax per month, capped at 25%. Interest is calculated daily and changes quarterly based on the federal short-term rate. Both begin accruing the day after the deadline.

You can reduce the failure-to-pay penalty if you request a payment plan or short-term extension before April 15. If you wait until May to ask, the penalty has already started and you cannot undo it. The sooner you contact the IRS or a tax professional, the lower your total cost.

If you owe a small amount—typically under $600—you can request a short-term extension of up to 120 days to pay in full. This is called a short-term extension agreement and does not require a formal application; you can request it by phone or through the IRS website. You still owe interest, but you may reduce the failure-to-pay penalty.

Setting up a payment plan with the IRS

If you owe more than you can pay at once, the IRS offers two types of payment plans: short-term (up to 120 days) and long-term (installment agreements lasting months or years).

A short-term plan is simpler and costs less. You pay the full amount within 120 days, usually in two or three installments. You still owe interest and penalties, but you avoid additional failure-to-pay penalties for missing the April 15 deadline if you set up the plan before that date.

A long-term installment agreement lets you pay over time—sometimes 24 months, sometimes longer depending on the amount you owe. The IRS charges a setup fee (typically $31 to $225 depending on how you set it up) and continues to charge interest and penalties until the balance is paid. You can set up an installment agreement online through the IRS website, by phone, or through a tax professional.

If you set up a payment plan after April 15, you still owe the failure-to-pay penalty for the months you were late. Setting up the plan before the deadline is always cheaper.

How to pay the IRS and when the payment is recorded

The IRS accepts payment through several methods, and the method you choose affects when the payment is recorded as received:

  • Online through IRS.gov: Payments are recorded the same day if submitted before 11:59 p.m. Eastern Time. This is the fastest method.
  • By phone: Call the IRS payment line and authorize a payment from your bank account. The payment is recorded the day you call.
  • By mail: Send a check or money order with a payment voucher to the address listed on your tax return. Payments are recorded when received, which can take two to three weeks. Mailing a check close to April 15 is risky because it may not arrive in time.
  • Through a tax professional: Your tax preparer or accountant can submit payment on your behalf, usually electronically.
  • Automatic bank draft: You can authorize the IRS to withdraw payment from your bank account on a date you choose. This is useful for installment plans.

The date the IRS records your payment as received is what matters for penalties, not the date you mailed it or the date your bank processes it. If you mail a check on April 14 and it arrives April 20, you are considered late. If you pay online on April 15 before midnight, you are on time.

State tax deadlines and how they differ from federal deadlines

Most states follow the federal April 15 deadline, but some states have different dates or no income tax at all. A few states—including Delaware, Iowa, and Virginia—have April 15 deadlines that are one or two days later than the federal deadline in some years. Some states allow you to file and pay on different dates.

If you live in a state with income tax, check your state's tax authority website for the exact deadline. Paying federal tax on time does not automatically mean you paid state tax on time. Missing a state deadline triggers state penalties and interest in addition to federal penalties.

Frequently Asked Questions

What if April 15 falls on a weekend or holiday?

The deadline moves to the next business day. If April 15 is a Saturday, the deadline becomes Monday April 17. If it falls on a Sunday, the deadline becomes Monday. If it falls on a federal holiday, the deadline moves to the next day that is not a holiday or weekend. The IRS announces the exact deadline each year.

Do I have to pay if I filed an extension request?

Yes. A filing extension gives you until October 15 to submit your return, but your tax payment is due April 15. If you owe and do not pay by April 15, you owe penalties and interest even though you have until October to file. Pay what you estimate you owe on April 15, then adjust when you file in October.

Can I pay my taxes in installments without requesting a plan first?

No. If you do not pay in full by April 15 and do not have an approved payment plan in place, you are considered late and penalties begin accruing. You must request a plan before or on April 15 to avoid additional penalties. Requesting a plan after the deadline does not erase the penalties you already owe.

What if I owe federal taxes and state taxes on different dates?

Pay each by its own deadline. Federal tax is due April 15. State deadlines vary by state. Missing either deadline triggers penalties from that state or the federal government. Check your state's tax website to confirm the state deadline in your state.

Does paying electronically cost extra?

The IRS does not charge a fee for paying through IRS.gov or by phone. Some payment processors charge a small fee (typically 1% to 2% of the payment) if you use a credit card or debit card. Paying by bank account draft or check costs nothing. Compare the fee against the cost of penalties if you delay payment.
