The fastest way to contact the IRS about a payment plan

The IRS has three main ways to reach them about payment plans: by phone, through their website, or by mail. The phone line is usually fastest if you have your tax documents ready. Call the IRS at 1-800-829-1040 during business hours (Monday through Friday, 7 a.m. to 7 p.m. your local time). Have your Social Security number, the tax year in question, and your most recent tax return nearby when you call.

If you prefer not to call, you can set up certain payment plans online through IRS.gov without speaking to anyone. This works best if you owe less than $50,000 and want a straightforward monthly payment arrangement. The online option is available 24 hours a day and gives you a confirmation number when ready.

Mail is the slowest option but works if you cannot reach the phone line or prefer written communication. You will need to send Form 9465 (Installment Agreement Request) to the IRS address for your state, which you can find on the form itself or on IRS.gov.

Key Takeaways

  • Call 1-800-829-1040 during business hours with your Social Security number and tax documents ready for the fastest phone support.
  • Use IRS.gov to set up a payment plan online if you owe less than $50,000 and want to avoid waiting on hold.
  • Mail Form 9465 to your state's IRS address if you cannot call or prefer written communication, though this takes several weeks.
  • Have your notice from the IRS (the letter telling you what you owe) available when you contact them, as it contains important account details.
  • The IRS will tell you during the call or online process what monthly payment amount they can accept based on what you owe.

What to have ready before you call

Gather these documents before dialing so you do not have to search while on the phone. You will need your Social Security number or Individual Taxpayer Identification Number (ITIN), the tax year you owe for, and your most recent tax return or a copy of the notice the IRS sent you. If you have already made any payments toward this debt, have those records handy too.

If you are calling about a business tax debt, have your Employer Identification Number (EIN) instead of a Social Security number. The IRS representative will ask you to verify this information before discussing your account.

Setting up a payment plan online through IRS.gov

The IRS Online Payment Agreement tool lets you create a payment plan without calling. Go to IRS.gov, search for "Online Payment Agreement," and follow the prompts. You will enter your Social Security number, the tax year, and the amount you owe. The system will show you what monthly payment the IRS will accept.

This online method works only if you owe $50,000 or less in combined taxes, penalties, and interest. You must also have filed your tax return for the year in question — you cannot set up a payment plan for a return you have not yet filed. Once you complete the online agreement, you will receive a confirmation number when ready. Write this down or print the confirmation page.

The online system is available 24 hours a day, seven days a week, so you can set this up at any time that works for you. However, if your situation is more complex — for example, if you owe for multiple years or have already received a notice of intent to levy — you will need to call instead.

What happens when you call the IRS

When you reach the IRS, a representative will verify your identity by asking for your Social Security number and other personal details. They will pull up your account and show you exactly what you owe, including the original tax, penalties, and interest. They will then ask about your financial situation to determine what monthly payment you can afford.

The IRS uses a formula based on how much you owe and your ability to pay. If you owe $10,000, they might offer you a payment of $200 to $300 per month. If you owe $50,000, the monthly payment will be higher. You can ask to pay less, but the IRS will explain that a lower payment means you will pay more in interest over time.

Once you agree to a monthly amount, the representative will confirm the payment plan and give you a confirmation number. They will also tell you when your first payment is due and how to make payments (usually by automatic bank withdrawal, credit card, or check).

Mailing Form 9465 if you prefer written communication

If you want to request a payment plan by mail, read Form 9465 (Installment Agreement Request) from IRS.gov or call 1-800-829-1040 to request it. Fill out the form with your name, Social Security number, the tax year, and the amount you owe. You can also write a brief explanation of why you need a payment plan, though this is not required.

Mail the completed form to the IRS address for your state. This address is printed on the back of Form 9465 and also listed on IRS.gov. Include a copy of the notice the IRS sent you if you have one. Do not send cash — the IRS will tell you how to pay once they receive your request.

Processing a mailed request takes four to six weeks. During this time, continue to avoid missing any payments if possible, as the IRS may take collection action while your request is being reviewed. Once approved, you will receive a letter confirming your payment plan and when your first payment is due.

Payment methods and what to expect after approval

Once your payment plan is approved, you can pay by automatic bank withdrawal (called a direct debit), credit or debit card, or check. Automatic withdrawal is the most reliable method and is often the only option the IRS will accept for certain payment plans. If you choose automatic withdrawal, the IRS will deduct your payment on the same day each month.

Your payment plan will remain in effect until you have paid off the full amount owed, including any interest that continues to accrue. If your financial situation changes and you cannot make the agreed payment, contact the IRS when ready to modify the plan. Skipping payments without notifying the IRS can result in the plan being cancelled and collection action resuming.

The IRS will send you a statement each year showing how much you have paid and how much remains. Keep these statements for your records. If you pay off the debt early, you can do so without penalty — there is no fee for paying ahead of schedule.

What to do if you cannot reach the IRS by phone

The IRS phone lines are often busy, especially during tax season (January through April). If you cannot get through after several tries, try calling early in the morning or late in the afternoon, when lines are typically shorter. You can also try calling on a weekday rather than near the weekend.

If you have tried calling multiple times without success, use the online payment agreement tool instead if your situation qualifies. This avoids the phone line entirely and gives you a confirmed agreement within minutes. If you do not may have access to for the online tool and cannot reach the phone line, mailing Form 9465 is your next option, though it takes longer.

The IRS also has a website chat feature on IRS.gov where you can ask questions about payment plans. This is not the same as setting up a plan, but a representative can answer questions about whether you may have access to and what documents you need.

Frequently Asked Questions

Can I set up a payment plan if I have not filed my tax return yet?

No. You must file your tax return for the year you owe before the IRS will set up a payment plan. If you have not filed, contact the IRS first to discuss filing your return. Once filed, you can then request a payment plan.

What if I owe more than $50,000?

You cannot use the online payment agreement tool if you owe more than $50,000. You will need to call 1-800-829-1040 or mail Form 9465 instead. For larger amounts, the IRS may require a more detailed financial review before approving a plan.

Do I have to pay interest while I am on a payment plan?

Yes. Interest and penalties continue to accrue on your tax debt even while you are making monthly payments. This is why the IRS encourages paying as much as you can afford each month — it reduces the total interest you will pay over time.

What happens if I miss a payment on my plan?

If you miss a payment, contact the IRS as soon as possible to explain. Missing one payment does not automatically cancel your plan, but repeated missed payments can result in the plan being terminated and collection action resuming. If your situation has changed, ask the IRS to modify your monthly payment amount.

Can I cancel my payment plan and pay the full amount instead?

Yes. You can pay off your tax debt in full at any time without penalty or fee. Contact the IRS to find out the exact amount owed, including current interest, and send a check or arrange a payment through their website.
