Tax Debt Payoff Calculator
Last updated · Reviewed for accuracy against IRS.gov guidance
To estimate how long it takes to pay off IRS debt, apply 7% annual interest plus the 0.25% monthly plan penalty to the balance each month and subtract your payment. If the payment doesn't cover the monthly interest, the balance grows — a sign you may need a different relief option.
About 5.4 years. This fits the online Simple Payment Plan range.

Each month the calculator adds one month of interest and plan penalty to the remaining balance, then subtracts your payment. It repeats until the balance reaches zero and reports the number of months and the total you'd pay. The math is the same as a loan payoff schedule, using the IRS's current underpayment rate of 7% plus the 0.25% monthly failure-to-pay penalty that continues during an installment agreement.
If your payment is less than one month's interest and penalty, the balance can never be paid off. The calculator tells you when that happens.
What the result means for your options
- Paid off within 72 months and you owe $50,000 or less: you're likely a fit for the online installment agreement.
- Paid off in more than 72 months, or you owe more: expect a financial statement; the IRS may set the payment from your income and allowable expenses.
- Not paid off before the 10-year collection statute: a partial-payment installment agreement or an Offer in Compromise may be worth reviewing. Compare them with the repayment vs settlement calculator.
- You can't afford any payment: see Currently Not Collectible.

How long will it take to pay off my IRS debt?
+
It depends on the monthly amount and the interest rate. Enter your balance and what you can pay each month to see the number of months, assuming interest and the reduced plan penalty keep accruing.
What if my payment doesn't cover the interest?
+
Then the balance never shrinks. The IRS may consider a partial-payment installment agreement or Currently Not Collectible status if you truly can't pay more.
Does the IRS have a time limit to collect?
+
Generally 10 years from the date the tax was assessed. Plans that run past that date are usually partial-payment agreements and need a financial review.
Should I pay extra when I can?
+
Yes. Extra payments reduce the principal immediately, so less interest accrues every day after. There's no prepayment penalty.
Is the interest rate fixed?
+
No. The IRS changes it quarterly. This calculator uses today's rate for the whole period.
