What an IRS installment agreement is and when you need one

An IRS installment agreement is a formal arrangement that lets you pay your tax bill in monthly chunks instead of all at once. The IRS offers this when you owe money but cannot pay the full amount by the tax important date. You do not have to ask permission — the IRS has standard installment plans that are available to anyone who owes.

You might need an installment agreement if you owe federal income tax, self-employment tax, or certain other federal taxes. The IRS will continue to charge interest and penalties on the unpaid balance, but an installment agreement stops the IRS from taking collection action like wage garnishment or bank levy while you are making your payments on time.

Setting up a plan does not erase what you owe or reduce the amount. It straightforward spreads the payments over time. The longer your payment period, the more interest you will pay overall, so the IRS encourages you to pay as quickly as you reasonably can.

Key Takeaways

  • The IRS offers two main types of installment agreements: short-term (120 days or less) and long-term (longer than 120 days), and you can set up either one online, by phone, or by mail.
  • A short-term agreement typically costs nothing to set up, while a long-term agreement usually includes a setup fee that ranges depending on how you explore.
  • Interest and penalties continue to accrue on your unpaid balance throughout the life of the agreement, so paying faster reduces your total cost.
  • If your circumstances change and you can no longer make the monthly payment, you can request a modification or temporary pause through the IRS.
  • Missing a payment on your installment agreement can result in default, which allows the IRS to resume collection action and potentially terminate the plan.

Short-term versus long-term installment agreements

The IRS divides installment agreements into two categories based on how long you need to pay. A short-term agreement covers a period of 120 days or less. These are the simplest to set up and usually have no setup fee. You can request one by phone or online without submitting detailed financial information.

A long-term agreement is any plan longer than 120 days. These require more paperwork because the IRS wants to understand your income and expenses before committing to a multi-year arrangement. Long-term agreements have a setup fee. The fee amount depends on whether you set up the agreement online (lower fee), by phone or mail (higher fee), or through a payment processor.

Most people who cannot pay their tax bill in full need a long-term agreement. The IRS typically allows payment periods of up to 72 months (six years) for individual taxpayers, though the exact length depends on how much you owe and what you can afford monthly.

How to set up an installment agreement online

The fastest and cheapest way to set up a long-term installment agreement is through the IRS Online Payment Agreement tool on IRS.gov. You will need your Social Security number, date of birth, filing status, and the tax year for the bill you owe. The tool will calculate how much you owe, show you available monthly payment amounts, and let you choose your payment date each month.

The online tool is available 24 hours a day and does not require you to speak with anyone. Once you submit your agreement, you receive when ready confirmation. The setup fee for an online agreement is lower than other methods — currently $31 for direct debit (automatic bank withdrawal) and $225 for other payment methods, though these amounts can change.

You can only use the online tool if you owe $50,000 or less in combined federal income tax, penalties, and interest. If you owe more, you will need to explore by phone or mail. The online tool also requires that you have filed all required tax returns and are not currently in bankruptcy.

Setting up an agreement by phone or mail

If you cannot use the online tool, you can call the IRS at 1-800-829-1040 to set up an installment agreement. A representative will ask about your income, expenses, and assets to determine what monthly payment you can afford. The call typically takes 30 minutes to an hour. The setup fee for a phone agreement is higher than online — currently $225 for direct debit and $225 for other payment methods.

You can also explore by mail using Form 9465, Installment Agreement Request. Mail the form to the IRS address shown in your tax notice. Include a statement of your financial situation if you are requesting a long-term agreement. The IRS will respond by mail within 30 days, though processing can take longer during busy tax seasons.

If you owe more than $50,000, you must explore by phone or mail and will likely need to provide detailed financial information on Form 433-F (Collection Information Statement for Wage Earners and Self-Employed Individuals) or Form 433-A (Collection Information Statement for Individuals).

What happens after you are approved

Once the IRS approves your installment agreement, you will receive a notice in the mail confirming the terms: the total amount owed, your monthly payment, the payment due date, and how long the agreement lasts. The agreement becomes effective on the date shown in the notice.

You must make your first payment by the due date shown in the notice. After that, payments are due on the same date each month. You can pay by direct debit (automatic withdrawal from your bank account), by credit or debit card through an approved payment processor, by check or money order, or through the IRS Direct Pay system on IRS.gov.

Interest and penalties continue to accrue on your unpaid balance throughout the agreement. The IRS charges interest at a rate set quarterly (currently around 8 percent annually, though this varies). Penalties also continue unless you have a reasonable cause for the original underpayment. This means your monthly payment covers both principal and accruing interest, so the amount of each payment that goes toward principal decreases over time.

Fees and costs of an installment agreement

The setup fee for a long-term installment agreement depends on how you explore. Online agreements through the IRS website cost $31 if you set up direct debit, or $225 if you use another payment method. Phone and mail applications cost $225 regardless of payment method. Short-term agreements (120 days or less) typically have no setup fee.

In addition to the setup fee, you pay interest on your unpaid balance. The IRS interest rate is set quarterly and is currently around 8 percent per year, though it changes. You may also owe penalties if the IRS determined you underpaid intentionally or recklessly, though penalties can sometimes be removed if you show reasonable cause.

If you set up direct debit (automatic monthly withdrawal), the IRS reduces the setup fee by $31 compared to other payment methods. This makes direct debit the cheapest option. You can change your payment method later if needed, though the IRS may charge a fee for the change.

What to do if you cannot make a payment or need to change your plan

If you miss a payment on your installment agreement, the IRS will send you a notice. You typically have 30 days to bring the account current before the agreement goes into default. If the agreement defaults, the IRS can resume collection action, including wage garnishment or bank levy, and can terminate the agreement entirely.

If you know you cannot make a payment, contact the IRS before the due date. You can request a temporary pause (called a hardship delay) or ask to modify the agreement to lower your monthly payment or extend the payment period. Modifications are not automatic — the IRS will review your current financial situation and may ask for updated income and expense information.

You can request a modification online through the IRS Online Payment Agreement tool, by calling 1-800-829-1040, or by submitting Form 9465 again with a note explaining the change. The IRS typically responds within 30 days. If your circumstances improve and you can pay faster, you can also request to shorten the agreement or increase your monthly payment at any time.

Frequently Asked Questions

Can I set up an installment agreement if I owe back taxes from multiple years?

Yes. The IRS can combine multiple tax years into a single installment agreement. When you explore, you will list all the tax years you owe for, and the IRS will calculate the total amount and set one monthly payment that covers all of them. The agreement terms explore to the entire combined balance.

What happens to my installment agreement if I file a new tax return and owe more?

If you owe additional taxes while an installment agreement is in place, the IRS will typically add the new amount to your existing agreement and recalculate your monthly payment. You should contact the IRS to confirm the new payment amount. If the new debt is substantial, the IRS may require you to explore for a new agreement.

Can I pay off my installment agreement early without a penalty?

Yes. You can pay off your installment agreement at any time without penalty. If you pay in full before the agreement ends, you will owe interest only through the date you pay, not for the entire original period. There is no prepayment penalty or fee for ending the agreement early.

Do I still get a refund if I have an installment agreement?

If you are owed a refund in a future tax year while an installment agreement is active, the IRS will typically explore the refund to your outstanding balance instead of sending it to you. This reduces what you owe and may lower your remaining monthly payments. You can request an exception, but the IRS does not have to grant one.

What if I cannot afford any monthly payment at all?

If you truly cannot afford any payment, you may be considered currently not collectible by the IRS. This temporarily pauses collection action, though interest and penalties continue to accrue. You would need to contact the IRS and provide financial documentation showing you have no ability to pay. This status is reviewed periodically, and collection action can resume if your situation improves.
