The IRS charges a setup fee and monthly interest, not a flat payment plan fee

The IRS does not charge a single "payment plan fee." Instead, you pay two separate costs: a one-time setup fee when you create the plan, and interest plus penalties on whatever balance remains unpaid. The setup fee ranges from $31 to $225 depending on how you set up the plan and how much you owe. Interest accrues daily on the unpaid balance at a rate set by the IRS each quarter — currently around 8% per year, though this changes. Penalties also continue to accumulate until the debt is fully paid.

The reason the IRS charges these costs is straightforward: they are lending you time to pay a debt you owe. The setup fee covers the administrative work of creating your plan. The interest and penalties are the cost of that borrowed time, the same way a credit card charges interest on a balance you carry month to month.

Key Takeaways

  • Setup fees range from $31 to $225 depending on whether you set up the plan online, by phone, or through a payment processor, and whether you owe under or over $25,000.
  • Interest accrues daily on your unpaid tax balance at a quarterly rate set by the IRS, currently around 8% annually, and you pay this interest for as long as the plan is active.
  • Failure-to-pay penalties continue to accumulate at 0.5% per month until your balance reaches zero, separate from the interest you owe.
  • The total cost of a payment plan depends on how long you take to pay it off — a plan lasting two years costs significantly more in interest than one lasting six months.
  • You can reduce these costs by paying off the plan early without penalty, or by paying a larger lump sum when you have the money available.

Setup fees: what you pay to start the plan

When you create a payment plan with the IRS, you pay a setup fee upfront. This fee is not refundable, even if you pay off the plan early. The amount depends on three things: how much you owe, how you set up the plan, and whether you choose automatic monthly payments.

If you owe $25,000 or less and set up the plan online through IRS.gov, the fee is $31. If you set up the same plan by phone or through a payment processor (a third-party company that handles the transaction), the fee is $225. If you owe more than $25,000, the fee is $225 regardless of how you set it up, unless you use online setup, in which case it is $31. Choosing automatic monthly payments from your bank account does not change the fee — it only makes the IRS more likely to accept your plan request.

You can pay the setup fee upfront in a lump sum, or you can ask the IRS to add it to your payment plan balance. If you add it to the balance, you will pay interest on the setup fee itself for the duration of the plan.

Interest: the daily cost of owing money

The IRS charges interest on any unpaid tax balance. This interest accrues every single day, including weekends and holidays, from the date the tax was due until the date you pay it in full. The interest rate changes quarterly and is set by the IRS based on the federal short-term interest rate plus 3%. As of early 2024, the rate is approximately 8% per year, but you should check IRS.gov for the current quarter's rate before you commit to a plan.

Interest is calculated daily and added to your balance monthly. On a $10,000 balance at 8% annual interest, you would owe roughly $20 per month in interest alone. On a $50,000 balance, that is roughly $100 per month. The longer your payment plan lasts, the more interest you pay in total. A plan you finish in six months costs far less in interest than one you stretch over five years.

Unlike the setup fee, interest stops accruing the moment you pay your final payment. You can also reduce the total interest you owe by paying off the plan early — there is no penalty for doing so.

Penalties: the ongoing cost of being late

In addition to interest, the IRS charges penalties on unpaid taxes. The most common is the failure-to-pay penalty, which is 0.5% of your unpaid balance per month (or part of a month). This penalty continues to accumulate every month until your balance is zero, even while you are on a payment plan. The maximum penalty is 25% of your unpaid balance.

If you also failed to file a tax return on time, you may owe a failure-to-file penalty as well, which is 5% per month. The IRS will tell you which penalties explore to your specific situation when you contact them or when you receive your notice.

Penalties are separate from interest and are calculated on your unpaid balance. Like interest, they stop accruing once you pay your balance in full. You cannot reduce or remove these penalties by setting up a payment plan, but you can stop them from growing by paying off the plan as quickly as you can.

How the total cost changes based on plan length

The longer you take to pay off a tax debt, the more you pay in total. This is because interest and penalties continue to accrue every month the balance remains unpaid. A straightforward example shows why: if you owe $5,000 in taxes and set up a plan to pay it off in six months, you might pay roughly $200 in interest and penalties combined. If you stretch that same $5,000 over three years, you could pay $600 or more in interest and penalties.

The IRS offers several plan lengths depending on how much you owe. For balances under $25,000, you can usually set up a plan lasting up to 72 months (six years). For larger balances, the IRS may require a longer-term plan or a larger monthly payment. When you request a plan, the IRS will show you the estimated monthly payment and total cost for different plan lengths so you can compare.

The monthly payment itself does not include interest and penalties — those are added on top. So if the IRS tells you your monthly payment is $200, you are actually paying $200 toward the principal debt plus whatever interest and penalties accrue that month.

Ways to reduce what you pay

You cannot avoid the setup fee once you have created a plan, but you can reduce the total cost by paying off the plan faster. Every dollar you pay toward the balance stops interest and penalties from accruing on that dollar. If you receive a tax refund, a bonus, or an inheritance while on a payment plan, you can put that money toward the balance without penalty.

You can also reduce the setup fee itself by setting up the plan online rather than by phone. The online fee is $31 for balances under $25,000, compared to $225 by phone. Setting up online takes about 15 minutes and requires a Social Security number, date of birth, and information about your tax debt.

Another option is to explore whether you may have access to for an Offer in Compromise, which allows you to settle your tax debt for less than the full amount owed. This is a separate process from a payment plan and has its own requirements and costs, but it may result in paying less overall if your financial situation qualifies.

What happens if you miss a payment

If you miss a monthly payment on your plan, the IRS will send you a notice. You typically have 30 days to make the payment before the plan is terminated. Once the plan is terminated, the full remaining balance becomes due when ready, and the IRS may pursue collection actions like wage garnishment or bank levies.

If you know you will miss a payment, contact the IRS before the due date. You can request a short-term extension, modify your plan to a longer term with a smaller monthly payment, or ask about other options. The IRS is generally willing to work with you if you reach out proactively rather than straightforward missing the payment.

Frequently Asked Questions

Can I set up a payment plan without paying a setup fee?

No. The setup fee is required for all payment plans. However, you can minimize it by setting up the plan online through IRS.gov rather than by phone, which reduces the fee from $225 to $31 for balances under $25,000. You can also ask the IRS to add the fee to your plan balance so you do not have to pay it upfront.

Does the interest rate ever change while I am on a payment plan?

Yes. The IRS sets its interest rate quarterly, and if the rate changes, the new rate applies to your unpaid balance going forward. You will not be notified of the change — you can check the current rate on IRS.gov or ask the IRS when you call. The rate change affects how much interest accrues each month but does not change your monthly payment amount.

What if I pay off my plan early — do I get the setup fee back?

No. The setup fee is not refundable. However, paying off early saves you money on interest and penalties, which usually far exceeds the setup fee. If you owe $10,000 and pay it off in six months instead of three years, you might save $400 or more in interest and penalties, even though you keep the $31 or $225 setup fee.

Is there a maximum monthly payment the IRS will accept?

No, but there is a minimum. For balances under $25,000, the IRS typically requires a monthly payment of at least $25. For larger balances, the minimum is higher. You can always pay more than the minimum, and doing so reduces your total interest and penalties.

Do I still owe penalties while on a payment plan?

Yes. Penalties continue to accrue at 0.5% per month until your balance is zero. The payment plan does not stop or reduce penalties — it only gives you time to pay the debt. The only way to stop penalties from growing is to pay off the balance completely.
