See how fast IRS penalties and interest grow on a balance you owe — and why filing now saves the most.
The IRS adds a failure-to-file penalty, a failure-to-pay penalty, and daily-compounded interest to every unpaid balance. See what yours has grown to — and how much filing now can save.
Educational estimate using 2026 federal rules: failure-to-file 5%/month (4.5% when the pay penalty also applies), failure-to-pay 0.5%/month (0.25% on an installment agreement, 1% after a levy notice), each capped at 25%; 60-day minimum failure-to-file penalty of $525; interest at the 2026 rate of 7%, compounded daily. Not tax advice — your actual figures depend on exact dates and IRS assessment. We can often reduce penalties with first-time abatement or reasonable-cause relief.
