An IRS late payment penalty is triggered when a taxpayer fails to pay the full amount of tax reported on their return by the original due date (usually April 15). It applies even if an extension to file was granted. The penalty is generally 0.5% of the unpaid taxes per month, capped at 25%.

How to avoid IRS late payment penalty?

How are IRS late payment penalties calculated?

What happens if you don't pay your taxes by April 15th?

If you can't pay your taxes by April 15, file your return anyway (even if you can't pay) to avoid the much steeper failure-to-file penalty, pay what you can, and then apply for an IRS payment plan (Installment Agreement) online for a short-term (up to 180 days) or long-term (monthly payments) plan, as penalties and daily compounded interest will accrue on the unpaid balance. 

Will the IRS negotiate penalties and interest?

We may be able to remove or reduce some penalties if you acted in good faith and can show reasonable cause for why you weren't able to meet your tax obligations. By law we cannot remove or reduce interest unless the penalty is removed or reduced. For more information, see penalty relief.
