The IRS has three main ways to set up a payment arrangement, and which one works depends on how much you owe and how quickly you need to start

You can reach the IRS by phone, online, or through the mail. The phone number is 1-800-829-1040 for individual tax matters. If you call, have your Social Security number, filing status, and the tax year in question ready. The IRS typically answers calls during business hours Monday through Friday, though wait times vary by season — they are longest during tax season (January through April) and shortest in summer and fall.

Online, you can set up a payment plan through IRS.gov without speaking to anyone, which is often faster. The IRS also accepts written requests by mail to the address shown on your tax notice. Mail is slowest — allow four to six weeks for a response — but it creates a paper record if you need one later.

Before you contact the IRS, gather these documents: your most recent tax return, your Social Security number, and the notice or bill showing what you owe. If you are calling on behalf of a business, you will need the Employer Identification Number (EIN) instead.

Key Takeaways

  • The IRS phone line is 1-800-829-1040, and you should call during business hours with your Social Security number and tax year ready.
  • Online payment plans through IRS.gov are often faster than phone or mail and do not require speaking to anyone.
  • The IRS offers short-term plans (120 days or less) for smaller amounts and long-term installment agreements for larger debts.
  • You must have filed your tax return to set up a payment plan, even if you cannot pay what you owe right now.
  • The IRS charges a setup fee and interest on the unpaid balance, so the total you pay will be more than the original amount owed.

Setting up a payment plan online through IRS.gov

The fastest route for most people is the Online Payment Agreement tool on IRS.gov. Go to the site, select "Payments," then "Set Up a Payment Plan." You will enter your Social Security number, filing status, and the tax year you owe for. The system will show you what the IRS has on file for that debt.

The online tool lets you choose between a short-term extension (up to 120 days with no setup fee) or a long-term installment agreement (monthly payments over several years). For the installment agreement, you pick your monthly payment amount and the date each month you want to pay. The IRS will then tell you the setup fee — typically $31 to $225 depending on the payment method you choose — and the total interest you will owe.

Once you confirm, the agreement is active when ready. You can start making payments right away through the same website, by phone, or by mail. The online tool works best if you owe less than $50,000 and have filed your return for the year in question.

Calling the IRS to discuss payment options

Call 1-800-829-1040 and tell the representative you want to set up a payment arrangement. They will ask for your Social Security number, filing status, and the tax year. Have your most recent tax return handy so you can answer questions about your income if they ask.

The representative will tell you how much you owe, including penalties and interest accrued to date. They will then walk you through payment plan options: a short-term extension if the amount is small, or a monthly installment agreement if you need longer. They can also discuss whether you might may have access to for an Offer in Compromise (a settlement for less than you owe) if your situation is severe, though this is rare and requires detailed financial information.

The call typically takes 15 to 30 minutes. The representative will confirm your payment plan details and send you a written agreement by mail within two weeks. Do not assume the plan is final until you receive and review the written agreement.

Mailing a payment plan request to the IRS

If you prefer to avoid the phone, you can mail a request. Use the address on the tax notice or bill you received — it will be specific to your region. Write a letter stating that you want to set up a payment plan, include your Social Security number, the tax year, and the amount you owe, and explain what monthly payment you can afford.

Attach a copy of your most recent tax return and any financial documents that show your income and expenses. The IRS uses this information to determine whether your proposed payment amount is reasonable. Mail the letter certified, return receipt requested, so you have proof the IRS received it.

Response time is typically four to six weeks. The IRS will send you a written agreement by mail. If they reject your proposed payment amount as too low, they will tell you why and may suggest a higher amount. You can then respond with a counter-proposal or call to discuss.

What happens after you set up a payment plan

Once your plan is in place, you owe the IRS a setup fee (usually $31 to $225) and interest on the unpaid balance. Interest accrues daily at a rate set by the IRS each quarter — currently around 8 percent per year, though this changes. You will pay more in total than the original tax bill because of these additions.

You must make your payment by the date you agreed to each month. If you miss a payment, the IRS will send you a notice. If you miss three payments in a row, the agreement may be cancelled and the full balance becomes due when ready. If your situation changes and you cannot afford the payment, contact the IRS right away to modify the plan rather than missing payments.

You can pay through the IRS website, by phone, by mail, or through an automatic bank withdrawal (which often has a lower setup fee). Keep records of every payment you make. If you pay by check or money order, include your Social Security number and tax year on the payment itself.

Short-term payment extensions versus long-term installment agreements

The IRS offers two main types of arrangements. A short-term extension gives you up to 120 days to pay in full with no setup fee. This works if you owe a small amount and expect to have the money soon — for example, if you are waiting for a bonus or a tax refund from another year. You still owe interest during this time.

A long-term installment agreement lets you pay in monthly installments over several years. The setup fee is higher ($31 to $225), and you owe interest for the entire period. This is the right choice if you cannot pay the full amount within four months. The IRS will work with you on the monthly amount, though they may reject a payment that is too low to cover interest and penalties within a reasonable timeframe.

The online tool will show you both options and the total cost of each. Compare them before you decide. A short-term extension costs less overall if you can actually pay in full within 120 days; an installment agreement is more realistic if you need years to pay off the debt.

If the IRS rejects your payment plan request

The IRS may reject your request if you have not filed a tax return for the year in question, if you are currently in bankruptcy, or if you owe more than $50,000 and did not use a professional tax representative to set up the plan. If this happens, the IRS will send you a notice explaining why.

If you have not filed your return, file it first — you cannot set up a payment plan without one. If you owe more than $50,000, you can still set up a plan by calling the IRS or mailing a request, though you may need to provide more financial documentation. If you are in bankruptcy, contact your bankruptcy trustee; they manage your debts during the process.

If your request was rejected for another reason, the notice will tell you what to do next. You can appeal or resubmit with additional information. Call the IRS at 1-800-829-1040 to discuss your options.

Frequently Asked Questions

Do I have to file my tax return before I can set up a payment plan?

Yes. The IRS will not set up a payment arrangement unless you have filed your return for the year you owe for. If you have not filed, file first — you can file and set up a payment plan in the same year, but the return must be filed before the plan can start.

What if I cannot afford the monthly payment the IRS suggests?

Contact the IRS and explain your situation. They may lower the payment, extend the timeline, or discuss other options like a short-term extension if your circumstances are temporary. Do not ignore the debt or stop paying; contact them proactively to modify the plan.

Can I pay off my plan early without a penalty?

Yes. You can pay off the full balance at any time without penalty. Paying early will reduce the total interest you owe, since interest stops accruing once the debt is paid in full.

What if I miss a payment?

The IRS will send you a notice. If you miss three payments in a row, your agreement may be cancelled and the full balance becomes due. Contact the IRS when ready if you cannot make a payment to discuss options before you fall behind.

How much does it cost to set up a payment plan?

The setup fee ranges from $31 to $225 depending on how you set up the plan and how you pay. Online and automatic bank withdrawal typically have lower fees. You also owe interest on the unpaid balance at the IRS rate, which changes quarterly.
