The formulas
- 2% if deposited 1 to 5 days late
- 5% if 6 to 15 days late
- 10% if 16 or more days late, or paid directly to the IRS or with the return
- 15% if still unpaid more than 10 days after the first IRS notice or on notice and demand
How it works
Publication 15 (2026) sets the deposit penalty by how late the deposit is, counted in calendar days from the due date: 2 percent for 1 to 5 days, 5 percent for 6 to 15 days, and 10 percent for 16 or more days before 10 days from the first notice. Amounts paid directly to the IRS or with the return instead of deposited are also 10 percent, and amounts unpaid more than 10 days after the first notice are 15 percent.
The penalty does not apply if the failure was due to reasonable cause and not willful neglect. The IRS applies a deposit to the most recent liability in the quarter; within 90 days of a penalty notice you may designate how deposits apply to reduce the penalty.

Common questions
Are weekends counted?
Yes. The days late are calendar days starting from the due date of the liability.
Is there first-time relief?
If the return was filed on time, the IRS may waive the penalty for an inadvertent failure in the first quarter you were required to deposit or the first time after your deposit frequency changed, subject to net worth and size limits.
