IRS installment agreement fees: what a payment plan costs to set up and change

IRS installment agreement fees by method

IRS installment agreement fees, which the IRS calls user fees, depend on two choices: how you apply and how you pay each month. Applying online and paying by direct debit is the cheapest combination. Applying by phone, mail or in person and paying by check or card is the most expensive.

The gap between the cheapest and most expensive long-term setup is $149. For most people, switching to the online application and agreeing to direct debit is the single easiest cost cut. The Online Payment Agreement works for individuals who owe $50,000 or less in combined tax, penalties and interest.

Is there a fee for a short-term plan?

No. A short-term plan gives you up to 180 days to pay a balance under $100,000, and the IRS charges no setup fee no matter how you apply. Interest and the failure-to-pay penalty still apply until the balance is paid.

If you are close to the line, it can be cheaper to stretch your budget for six months than to take a long-term plan and pay a setup fee. Our short-term payment plan page explains how to request one.

The IRS payment plan fee waiver for low-income taxpayers

You count as low-income for this purpose if your adjusted gross income for the most recent year the IRS has on file is at or below 250% of the federal poverty guidelines for your household size. The IRS checks this when you apply.

• With direct debit: the setup fee is waived entirely, whether you apply online or by phone or mail.
• Without direct debit: you pay a reduced $43 fee. The IRS reimburses it when you finish the plan, if you meet the conditions. On Form 9465, checking line 13c asks for that reimbursement.
• If the IRS does not flag you as low-income: file Form 13844, Application for Reduced User Fee for Installment Agreements, to ask for a review.

Installment agreement user fee for changes and reinstatement

Once a plan is running, some changes cost money and some do not. The IRS online account lets you change the monthly amount, change the due date, convert to direct debit, update bank details and reinstate a plan after a default.

A default notice such as CP523 warns that reinstatement may carry a fee. Fixing the problem online before the termination date is the lowest-cost path. If you let the plan terminate and apply for a new one, you may face a new setup fee instead.

How interest compares to fees

The setup fee is paid once. Interest and the failure-to-pay penalty are charged every month the balance is open, and they keep running on every plan until you pay in full.

Take a $12,000 balance. At the 7% underpayment rate in effect for the fourth quarter of 2026, compounded daily, the first month of interest is roughly $70. If you filed on time and have an approved plan, the failure-to-pay penalty drops to 0.25% a month, about $30 on that balance. That is around $100 in the first month alone, compared with a one-time fee of $29 to $178.

The takeaway: a lower fee helps, but paying the balance down faster saves more. Every extra dollar you pay early stops interest on that dollar. The rate for January to March 2027 has not been announced yet; the IRS usually publishes the next quarter's rate in late November. Our underpayment interest rate page tracks each quarter, and the payment plan calculator estimates your total cost.

How much does an IRS payment plan cost in total?

Add three pieces: the setup fee, the interest on the declining balance, and the failure-to-pay penalty on the unpaid tax. The fee is fixed. The other two depend on how much you owe and how fast you pay.

1. Choose the shortest term you can keep up with. A 36-month plan costs less in interest than a 72-month plan on the same balance.
2. Apply online and choose direct debit to get the $29 fee.
3. File every return on time while the plan is active, which keeps the 0.25% penalty rate and avoids default.
4. Make extra payments whenever you can; there is no penalty for paying early.
5. If a penalty was charged for a year with a clean history, ask whether first-time or automatic relief applies, because removing a penalty also removes the interest on it.
