Do IRS Payment Plans Charge Interest and Penalties?

IRS payment plans are not interest-free, but the interest rate is set by law

No, IRS payment plans do not charge interest-free payments. The IRS charges interest on any tax you owe, whether you pay in full when ready or spread the payments over time. The interest rate changes quarterly and is currently in the range of 8% per year, though this varies. You will also owe a penalty on top of the interest — usually 0.5% of your unpaid tax per month — unless you have a specific reason the IRS accepts for the delay.

The interest and penalties are separate from your payment plan itself. A payment plan is straightforward an agreement about when you will pay; it does not reduce what you owe. Think of it this way: the IRS first calculates how much tax you owe, then adds interest and penalties to that amount, then lets you pay the total in installments instead of all at once.

The benefit of a payment plan is not that it costs less — it is that you can afford to pay without borrowing money or emptying your savings in one month. If you can pay your tax bill in full right away, you will pay less total interest because the interest accrues for a shorter time.

Key Takeaways

• The IRS charges interest on unpaid tax at a rate set by law each quarter, currently around 8% per year.
• You will also owe a failure-to-pay penalty of 0.5% per month on top of the interest, unless the IRS waives it for reasonable cause.
• A payment plan spreads your payments over time but does not reduce the total interest and penalties you owe.
• The longer you take to pay, the more interest accumulates, so paying faster costs you less even if you have to borrow to do it.
• You can request that the IRS remove or reduce penalties if you have a valid reason for not paying on time, such as a serious illness or death in the family.

How interest is calculated on a payment plan

Interest on IRS debt is calculated daily on the amount you still owe. If you owe $5,000 and set up a 12-month payment plan, the interest does not stay the same each month — it decreases as you pay down the balance. In the first month you might owe $33 in interest (roughly 8% of $5,000 divided by 12), but in the last month you might owe only $3 in interest because you have already paid most of the original debt.

The IRS publishes its interest rate each quarter in the Federal Register. The rate is the federal short-term rate plus 3 percentage points. Because the federal rate changes, the IRS rate changes too. You can find the current rate on the IRS website under "Interest Rates" — it is usually between 7% and 9% per year, though it has been higher in the past.

When you receive a notice from the IRS showing what you owe, that amount already includes interest calculated up to the date of the notice. Once you set up a payment plan, interest continues to accrue on the unpaid balance until you pay it off completely.

Penalties that add to what you owe

The failure-to-pay penalty is separate from interest. It is 0.5% of your unpaid tax for each month or part of a month that the tax remains unpaid. If you owe $5,000 and do not pay for six months, you will owe an additional $150 in penalties (0.5% × 6 months × $5,000) on top of the interest.

There is also a failure-to-file penalty if you did not file your tax return on time. This is usually 5% of the unpaid tax for each month the return is late, up to 25% total. If you both filed late and paid late, the IRS may reduce the failure-to-file penalty by the failure-to-pay penalty to avoid double-counting.

The IRS can remove or reduce these penalties if you show reasonable cause — meaning you had a good reason you could not pay or file on time. Common reasons include serious illness, a death in the family, a fire or natural disaster, or reliance on a professional tax preparer who made an error. You have to request this in writing and explain your situation. The IRS does not automatically remove penalties just because you set up a payment plan.

Types of IRS payment plans and their costs

The IRS offers three main types of payment plans: short-term, long-term, and installment agreements. A short-term plan lets you pay within 180 days with no setup fee. A long-term installment agreement spreads payments over more than 180 days and charges a setup fee, usually between $31 and $225 depending on how you set it up.

If you set up an installment agreement online through the IRS website or by phone, the fee is lower than if you do it by mail or in person. You can also request a reduced fee if your income is below a certain threshold. The setup fee is added to what you owe, so it increases the total amount subject to interest.

A Direct Debit Installment Agreement, where the IRS automatically withdraws money from your bank account each month, has a lower setup fee than other methods. This is the cheapest way to set up a long-term plan if you can commit to automatic payments.

What happens if you miss a payment on your plan

If you miss a payment on an IRS installment agreement, the agreement can be terminated. Once it is terminated, the full unpaid balance becomes due when ready. The IRS will send you a notice giving you 30 days to pay or to request a new agreement.

Missing a payment also means interest and penalties continue to accrue on the unpaid balance. You do not lose the time you already spent paying down the debt, but you lose the protection of the agreement itself. If the IRS demands full payment and you cannot pay, you may end up with a tax lien or wage garnishment.

If you know you will miss a payment, contact the IRS before the due date. You can request a short-term extension or ask to modify your agreement. The IRS is more willing to work with you if you reach out first rather than straightforward missing the payment.

Comparing the cost of paying now versus a payment plan

Whether a payment plan makes sense depends on your situation. If you can borrow money at a lower interest rate than the IRS charges, borrowing might cost less. For example, if you can get a personal loan at 5% interest and the IRS charges 8%, paying the loan off with borrowed money and then repaying the loan would cost less in interest.

However, most people cannot borrow at rates lower than the IRS rate, and taking on debt has its own risks. A payment plan lets you pay from your regular income without borrowing. The tradeoff is that you pay more in total interest the longer you take, but you avoid the risk of defaulting on a loan.

You can use an online calculator to estimate how much interest you will pay under different payment schedules. The IRS website has a tool that shows the total cost of various payment plans so you can compare before you commit.

How to request penalty relief

If you believe you have reasonable cause for not paying on time, you can request that the IRS remove or reduce your penalties. You do this by filing Form 843, Claim for Refund and Request for Abatement, or by including a written request with your payment plan process.

Reasonable cause means the IRS believes you exercised ordinary care and prudence but still could not pay on time. Examples include serious illness that prevented you from handling your finances, a death in the family, a fire or flood that destroyed your records, or reliance on a tax professional who gave you wrong information. straightforward not having enough money is not usually considered reasonable cause unless it resulted from circumstances beyond your control.

The IRS reviews each request individually. You have a better chance of success if you provide documentation — a doctor's letter about illness, a death certificate, photos of fire damage, or an email from your tax preparer admitting the error. Include a brief explanation of what happened and why you could not pay or file on time.

Frequently Asked Questions

Can I get an interest-free payment plan from the IRS?

No. The IRS is required by law to charge interest on unpaid tax. The interest rate is set quarterly and is currently around 8% per year. A payment plan does not reduce or eliminate this interest — it only spreads your payments over time.

What is the current IRS interest rate?

The IRS interest rate changes each quarter. You can find the current rate on the IRS website under "Interest Rates — Current Rates and Periods." The rate is typically between 7% and 9% per year, though it varies based on the federal short-term rate.

Will my penalties go away if I set up a payment plan?

No. Penalties continue to accrue until you pay your tax in full. You can request that the IRS remove or reduce penalties by filing Form 843 and explaining your reasonable cause, but setting up a payment plan alone does not remove them.

Is it cheaper to borrow money and pay the IRS in full?

It depends on the interest rate you can borrow at. If you can borrow at less than the IRS rate, borrowing and paying in full costs less total interest. However, most personal loans charge more than 8%, so a payment plan is often the cheaper option if you cannot pay in full when ready.

What happens if I cannot make a payment on my plan?

Contact the IRS before the payment is due. You can request a short extension or ask to modify your agreement. If you miss a payment without contacting the IRS, your agreement may be terminated and the full balance becomes due when ready.
