How to Pay Your IRS Taxes: Methods, Timing, and What Happens If You Can't

How the IRS accepts tax payments

The IRS takes payments through five main channels: the IRS Direct Pay system (online, no fee), Electronic Federal Tax Payment System or EFTPS (online or phone, no fee), credit or debit card (online, with a processor fee), ACH debit from your bank account (online, no fee), and check or money order by mail. Each method moves money differently and has different deadlines, so the one you choose affects when the IRS actually receives your payment and whether penalties apply.

Direct Pay and EFTPS are the fastest and cheapest routes. Direct Pay lets you schedule a payment up to 120 days in advance and see confirmation the same day. EFTPS requires you to enroll first (which takes one to two business days) but then works the same way. Both pull money straight from your bank account with no middleman fee. If you owe less than $25,000 and want to pay today, Direct Pay is usually the quickest path.

Credit and debit card payments go through a third-party processor — Worldpay, Paymetrics, or Global Payments — and each charges a fee (usually 1.87 to 2.35 percent of the amount you pay). The IRS does not charge this fee; the processor does. You get a confirmation number immediately, but the IRS may not receive the payment for one to three business days. Use a card only if you need the points or rewards and can afford the fee, or if you cannot access your bank account.

Key Takeaways

• Direct Pay and EFTPS are free and the fastest ways to pay; both let you schedule payments in advance and confirm receipt the same day.
• The IRS deadline for tax payments is usually April 15, but payments made by midnight on that date count as on-time, even if your bank processes them the next day.
• If you cannot pay in full by the deadline, you can request a short-term extension (up to 180 days) or set up a payment plan; both stop failure-to-pay penalties from growing while you arrange the money.
• Payments by check or money order must be postmarked by the deadline and include your Social Security number, tax year, and form type on the check itself.
• Late payments accrue a failure-to-pay penalty of 0.5 percent per month, plus interest on the unpaid balance; setting up a plan or requesting relief stops the penalty from compounding.

Payment deadlines and what "on-time" means

The standard tax deadline is April 15 of the year following the tax year you are paying for. If April 15 falls on a weekend or federal holiday, the deadline moves to the next business day. The IRS counts a payment as on-time if it is submitted by midnight on the deadline date, even if your bank does not process it until the next day. This matters because banks can take one to three business days to clear a payment, and the IRS will not penalize you for your bank's processing time if you submitted before midnight.

For payments by mail, the postmark date is what counts, not the date the IRS receives it. A check postmarked April 15 is on-time even if it arrives at the IRS on April 20. Write your Social Security number, the tax year, and the form type (1040, 1120, etc.) on the check itself so the IRS can match it to your account. Mail payments to the address listed on your tax form or the IRS website for your state.

If you file for an extension to file your return, that extension does not extend your payment deadline. You still owe payment by April 15, even if you have until October 15 to file the return itself. The extension only gives you more time to gather documents and prepare the return; the IRS expects payment on the original date.

What to do if you cannot pay by the deadline

If you know you cannot pay in full by April 15, contact the IRS before the deadline rather than after. The IRS offers two main options: a short-term extension and a payment plan. A short-term extension gives you up to 180 days to pay without setting up a formal agreement. You request it by calling the IRS at 1-800-829-1040 or through your online IRS account. During those 180 days, the failure-to-pay penalty (0.5 percent per month) stops growing, though interest continues to accrue on the unpaid balance.

A payment plan (also called an installment agreement) lets you pay over months or years. The IRS offers three types: a short-term plan (up to 180 days, no setup fee), a long-term plan (more than 180 days, with a setup fee of $31 to $225 depending on how you enroll), and a streamlined plan (for balances under $50,000, with lower fees). You can set up a plan online through your IRS account, by phone, or by mail. Once approved, you make monthly payments on a schedule you agree to. The failure-to-pay penalty still applies, but at a reduced rate (0.25 percent per month instead of 0.5 percent) while you are on the plan.

If you cannot pay even with a plan, you can request Currently Not Collectible status, which temporarily pauses collection action. The IRS will stop sending notices and will not garnish your wages or levy your bank account while you are in this status. Interest and penalties still accrue, but you are not in active default. You must reapply every two years, and the IRS may end the status if your financial situation improves.

How penalties and interest work on unpaid taxes

When you do not pay by the deadline, two separate charges begin: the failure-to-pay penalty and interest. The failure-to-pay penalty is 0.5 percent of the unpaid tax for each month or part of a month the tax remains unpaid. This means if you owe $5,000 and do not pay for three months, you owe an additional $75 in penalties (0.5 percent × 3 months × $5,000). The penalty caps at 25 percent of the unpaid tax, so it stops growing once you hit that ceiling.

Interest accrues daily on both the unpaid tax and the penalties. The IRS sets the interest rate quarterly; it is currently between 8 and 10 percent per year depending on the quarter, but this rate changes. Interest compounds, meaning you pay interest on the interest. A $5,000 unpaid balance for one year at 8 percent interest costs $400 in interest alone, plus the penalties on top of that.

If you set up a payment plan or request an extension before the deadline, the failure-to-pay penalty drops to 0.25 percent per month instead of 0.5 percent. This is why contacting the IRS early matters: you cut the penalty rate in half just by asking for help before you are late. Interest still accrues at the same rate, but the penalty grows more slowly.

Paying through an employer or third-party payment processor

If you owe taxes because your employer did not withhold enough from your paycheck, you cannot ask your employer to pay the IRS on your behalf. You must pay the IRS directly. However, some employers offer payroll deduction plans that let you authorize the IRS to deduct money from your paycheck each pay period until your tax debt is paid. This is not the same as withholding; it is a voluntary arrangement between you and the IRS. You set it up through your IRS account or by calling 1-800-829-1040.

If you use a tax preparation service or a CPA to file your return, they can submit your payment electronically on your behalf, but only if you authorize them in writing. The payment still comes from your bank account or card; the tax preparer is just the intermediary. Make sure you know which payment method they are using and whether there is a fee. Some tax preparers charge extra to submit payments, while others include it in their filing fee.

Tracking your payment and getting a receipt

Every payment method gives you a confirmation number or receipt. For Direct Pay and EFTPS, you receive a confirmation number immediately on screen. For credit or debit card payments, the processor gives you a confirmation number and a receipt showing the fee charged. For checks, the IRS does not send a receipt, but you can track payment status through your online IRS account under "Payment History" about one to two weeks after mailing.

Your online IRS account (at IRS.gov, under "View Your Tax Account") shows all payments received, the date received, and the amount applied to your account. This is the official record. If a payment does not appear within two weeks of submission, call the IRS at 1-800-829-1040 with your confirmation number. Do not assume the payment was lost; the IRS can locate it by confirmation number and tell you when it will post to your account.

Keep your confirmation number and receipt for at least three years. If the IRS ever claims it did not receive a payment, your confirmation number is proof that you submitted it. The IRS will investigate and correct the record if the payment was lost in processing.

What happens if you miss the deadline

Missing the April 15 deadline triggers the failure-to-pay penalty immediately, even if you pay the next day. The penalty accrues from April 16 onward. However, the IRS can waive penalties in certain situations: if you have a clean payment history and this is your first late payment, if you had a serious illness or death in the family, or if you relied on bad advice from a tax professional. You must request penalty relief in writing, either through your IRS account or by mail, and provide documentation of the reason.

If you do not pay within 10 days of receiving a final notice from the IRS, the agency can place a federal tax lien on your property. A lien is a legal claim against your assets; it does not seize them, but it prevents you from selling or refinancing property without paying the tax debt first. The lien stays on your credit report and can affect your ability to borrow money. After 120 days of non-payment, the IRS can also levy your bank account or garnish your wages. A levy is different from a lien: it actually takes money from your account or paycheck.

If you receive a notice of intent to levy, you have the right to request a hearing with the IRS Office of Appeals before the levy happens. This is called a Collection Due Process hearing. You can request it by mail or phone within 30 days of the notice. At the hearing, you can propose a payment plan or other arrangement to stop the levy. If you do not request a hearing, the levy can proceed.

Frequently Asked Questions

Can I pay my taxes with a credit card to earn rewards points?

Yes, but the processor fee (usually 1.87 to 2.35 percent) often exceeds the rewards you earn. If you owe $5,000 and pay with a card earning 2 percent cash back, you earn $100 but pay $94 to $118 in fees — a net loss. Pay with a card only if the rewards rate is higher than the fee or if you cannot access your bank account.

What if I pay late but then file for an extension to file my return?

The extension to file does not erase the late payment penalty. You owed payment by April 15 regardless of when you file the return. However, if you file the return and pay within the extension period, you may be able to request penalty relief if you have a good reason for the delay.

Can I set up a payment plan over the phone?

Yes. Call the IRS at 1-800-829-1040 and request an installment agreement. You will need your Social Security number, the tax year, and the amount owed. The IRS will ask about your income and expenses to determine what monthly payment you can afford. You can also set up a plan online through your IRS account without calling.

Do I have to pay state taxes by the same deadline as federal taxes?

No. State tax deadlines vary by state. Most states align with the federal April 15 deadline, but some have different dates. Check your state's tax agency website for the exact deadline. Penalties for late state tax payments are separate from federal penalties.

What if the IRS says I owe money but I disagree with the amount?

Do not ignore the notice. You have the right to dispute the amount through the IRS Office of Appeals. You can request a hearing by mail or phone within 30 days of the notice. Bring documentation of your income, deductions, and any payments you made. If you still disagree after the hearing, you can take the case to Tax Court, but you must request it within 90 days of the IRS's final notice.
