IRS alerts taxpayers to $525 fines with interest if you miss this key 60-day rule

The Internal Revenue Service (IRS) has warned that millions of Americans could face penalties of up to $525 if they break an important tax rule. The agency said people must be careful about a key 60-day rule, because missing it can trigger big fines plus extra interest, as per IRS notice. The 2026 tax season started on January 26, and most taxpayers must file by April 15, or October 15 if they took a six-month extension.

If someone does not file their tax return on time, they will get a “failure to file” penalty, also called a delinquency penalty. For most individuals and businesses, the penalty is 5% of unpaid tax for each month the return is late, as per IRS rules. This penalty keeps adding every month and can reach a maximum of 25%. If a tax return is more than 60 days late, the minimum penalty becomes $525 or 100% of unpaid tax (whichever is less) for returns due after Dec 31, 2025.

Interest keeps growing

The IRS also charges interest on unpaid penalties, which keeps growing until the full amount is paid, according to the agency statement. The IRS said interest usually starts from the due date of the tax bill and continues until payment is complete, as per IRS explanation. Taxpayers who owe penalties will receive an official notice or letter from the IRS. People will not be charged extra interest if they pay the full amount by the “pay by” date written in the notice.


Paying taxes fully or sending partial payments can stop future penalties and interest from increasing. The IRS may reduce or remove penalties if a taxpayer shows they acted in good faith and had a valid reason. However, the IRS said interest cannot be removed unless the penalty itself is reduced or cancelled. Valid reasons for penalty relief may include natural disasters, serious illness, death in family, missing records, or system errors.

How to avoid fines

Invalid excuses include not knowing tax rules, depending only on a tax expert, mistakes, or not having money. Taxpayers can dispute the penalty if they think the amount is wrong. People can avoid penalties completely by filing and paying taxes on time. Those who cannot file on time can apply for an extension, but this only gives more time to file — not more time to pay taxes. Taxpayers who cannot pay fully can also apply for a payment plan with the IRS, according to the agency guidance.
