How to Pay Your IRS Tax Bill

You can pay the IRS directly through their official payment channels, by mail, or through a payment plan if you owe more than you can pay right now.

The IRS offers several ways to settle a tax bill. You can pay in full when ready online, by phone, or by mail. If you cannot pay the full amount, you can set up a payment plan (called an installment agreement) that lets you pay over time, or you can request a short delay while you gather funds. The IRS charges interest and penalties on unpaid taxes, so the sooner you pay or set up a plan, the less you will owe in the long run.

Your first step is to know exactly what you owe. This amount appears on your tax notice from the IRS, usually a letter that says "Notice of Tax Due and Demand for Payment" or similar. If you have not received a notice but believe you owe, you can check your account on IRS.gov using your Social Security number or Individual Taxpayer Identification Number.

Key Takeaways

• You can pay the IRS online, by phone, or by mail using the amount shown on your tax notice.
• Online payment through IRS.gov or an approved payment processor is the fastest method and shows confirmation when ready.
• If you cannot pay in full, you can request a payment plan that spreads the debt over months or years, though interest and penalties continue to accrue.
• Payment plans require a setup fee (usually $31 to $225 depending on the plan type) in addition to your tax debt.
• The IRS accepts checks, money orders, and electronic transfers, but does not accept credit cards or debit cards by mail.

Paying the full amount online or by phone

The fastest way to pay is through the IRS website at IRS.gov. Go to the "Payments" section and select "Pay Now." You will need your Social Security number or ITIN, the tax year the bill is for, and the exact amount owed from your notice. The IRS offers several payment processors — including EFTPS (Electronic Federal Tax Payment System), IRS Direct Pay, and third-party processors like Paypal, Stripe, and others. Most charge no fee if you pay by bank account transfer; some charge a fee if you use a debit or credit card.

You can also call the IRS at 1-800-829-1040 to pay by phone. A representative will take your payment information and process it over the phone. This method works if you prefer speaking to someone, but it takes longer than online payment.

Payment by phone or online typically posts to your account within one business day. You will receive a confirmation number when ready — save this for your records.

Paying by mail with a check or money order

If you prefer to pay by mail, send a check or money order to the IRS address listed on your tax notice. Do not send cash. Include a copy of your notice with the payment so the IRS knows which tax year and which account the payment is for. Write your Social Security number and the tax year on the check or money order itself.

Mail payments take longer to process — typically two to three weeks — so if you are close to a important date, paying online or by phone is safer. If you need proof of payment for your records, keep a copy of the check or the money order receipt.

The IRS mailing address varies by state and type of tax. Your notice will show the correct address. If you have lost your notice, you can find the address on IRS.gov under "Where to File" or call 1-800-829-1040.

Setting up a payment plan if you cannot pay in full

If you owe more than you can pay when ready, you can request an installment agreement that lets you pay the debt in monthly installments. The IRS offers two main types: a short-term plan (120 days or fewer) and a long-term plan (more than 120 days).

To set up a plan, go to IRS.gov and select "Payment Plans" under the Payments section, or call 1-800-829-1040. You will need to provide your income, expenses, and how much you can pay each month. The IRS will calculate a monthly payment amount based on what you can afford and how long you want the plan to last.

There is a setup fee for an installment agreement. Short-term plans cost $31, and long-term plans cost $31 to $225 depending on whether you pay by bank transfer or other method. This fee is added to your total debt. Interest and penalties continue to accrue on the unpaid balance, so the longer the plan lasts, the more you will pay overall.

Requesting a delay if you need more time

If you need a short delay to gather funds but do not want to commit to a long payment plan, you can request a short-term extension. This gives you up to 120 days to pay without setting up a formal installment agreement. There is no fee for a short-term extension, but interest and penalties still accrue on the unpaid amount.

You can request an extension by calling 1-800-829-1040 or through IRS.gov. The IRS will ask why you need the delay and will verify that you can pay within 120 days. If approved, you will receive a letter confirming the new due date.

What happens if you do not pay

If you do not pay or set up a plan, the IRS will add penalties and interest to your bill each month. After a certain period, the IRS may place a tax lien on your property or issue a levy to seize funds from your bank account or wages. A lien makes it hard to sell property or borrow money; a levy takes money directly without your permission.

If you are in financial hardship and cannot pay even a small amount, you can request Currently Not Collectible (CNC) status. This temporarily pauses collection efforts while you recover financially, though interest and penalties still accrue. CNC is not forgiveness — you still owe the debt, and collection may resume later.

Understanding interest and penalties

The IRS charges interest on all unpaid taxes. The interest rate changes quarterly and is currently in the range of 8 to 9 percent annually, though this varies. You also pay a failure-to-pay penalty of 0.5 percent of the unpaid tax per month (up to 25 percent total). If you filed your return late, there may be an additional failure-to-file penalty.

These charges are calculated daily and added to your bill. The longer you wait to pay, the more interest and penalties you owe. Setting up a payment plan does not stop these charges, but it does prevent the IRS from taking collection action like levies or liens.

Frequently Asked Questions

Can I pay my IRS bill with a credit card?

Yes, but only through approved payment processors on IRS.gov, and they charge a processing fee (usually 1.87 to 2.35 percent of the payment). You cannot pay by credit card by mail or phone. Paying by bank account transfer through IRS Direct Pay or EFTPS has no fee.

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

You can dispute the bill by filing a formal protest or requesting an appeals conference. Contact the IRS at the number on your notice to request this. You should do this before paying, though you can also pay while disputing if you want to stop interest from accruing.

How long does a payment plan last?

Short-term plans last up to 120 days. Long-term plans can last several years depending on the amount owed and your ability to pay. The IRS will work with you to set a monthly payment you can afford, but longer plans mean more interest and penalties overall.

Will setting up a payment plan hurt my credit score?

A payment plan itself does not appear on your credit report. However, if the IRS places a tax lien on your property (which happens if you do not pay or set up a plan), that lien may appear on your credit report and lower your score.

Can I change my payment plan if my situation changes?

Yes. You can contact the IRS to modify your monthly payment amount or the length of the plan if your income or expenses change. Call 1-800-829-1040 or log into your IRS account online to request a modification.
