What is the IRS payment plan interest rate now?
If the interest worries you, the first step is a call to a licensed tax pro. They show you what the rate means for your own balance. The IRS confirmed the rate stays at 7%.
The IRS sets the rate each quarter as the federal short-term rate plus 3 percentage points, per its quarterly interest rate page. Interest compounds daily, so today's interest is charged on yesterday's interest too. The table below shows each quarter of 2026.
| Quarter | Rate |
|---|---|
| January to March | 7% |
| April to June | 6% |
| July to September | 7% |
| October to December | 7% |
How big is the penalty while you pay?
Without a plan, the late-payment penalty is 0.5% of the unpaid tax each month. File on time and get an approved plan, and it drops to 0.25%, per the IRS failure to pay penalty page.
The penalty never goes past 25% of the unpaid tax. It jumps to 1% a month if you don't pay within 10 days of a notice of intent to levy. A tax pro can get your plan in place before that happens.
What does $15,000 over 4 years cost?
David owes $15,000 and filed his return on time. He applies online with automatic withdrawals, so his setup fee is $29. The math uses the 7% yearly rate and the 0.25% monthly penalty.
Filing on time saves David about $1,056 over the 4 years. A late return would push his total to $19,344.
| Item | Amount |
|---|---|
| Monthly payment | $381 |
| Interest | $2,288 |
| Late-payment penalty | $981 |
| Setup fee | $29 |
| Total paid | $18,288 |
| Total if filed late (0.5% penalty) | $19,344 |
How can you pay less interest on a plan?
Four moves cut the cost of a plan. A tax pro on the call works out which ones fit your budget.
The IRS applies each payment to the tax first, then the penalty, then interest, per Topic 653. Try your own numbers on the payment plan calculator.
- Pay more each month. Every extra dollar stops interest on that dollar.
- Apply online with automatic withdrawals for a $29 fee, against $178 for a mailed plan paid by hand.
- File every return on time, so the penalty stays at 0.25%.
- Compare a bank loan. The IRS itself says a loan rate can be lower than its interest plus penalties.
