Penalties and Interest

When the Cost of Owing Grows Faster Than the Tax Itself

The principal tax you owe is only part of the bill. The IRS imposes separate penalties for failing to file, failing to pay, and making accuracy-related mistakes on your return—and each one compounds on top of the last. What starts as a manageable balance can double within a year if left unaddressed.

At Alan Goldstein & Associates, we help taxpayers understand exactly how penalties and interest are calculated, identify opportunities for abatement, and stop the cycle before it spirals further.

The Issue: How Penalties and Interest Snowball

Failure-to-File Penalty (The Steepest Charge)

If you do not file your return by the due date or extended due date, the IRS assesses a failure-to-file penalty of 5% of the unpaid tax for each month or part of a month the return is late, capped at 25% of the unpaid tax .

If your return is more than 60 days late, a minimum penalty applies: the smaller of $525 (for returns required to be filed in 2026) or 100% of the tax owed .

Failure-to-Pay Penalty (Persistent and Monthly)

Even if you file on time, failing to pay the balance by the due date triggers a failure-to-pay penalty of 0.5% of the unpaid tax per month, also capped at 25% .

The rate increases to 1% per month if the IRS issues a final notice of intent to levy and you do not pay within 10 days. It decreases to 0.25% per month while an approved installment agreement is in effect .

The Combined Penalty Rule

When both penalties apply in the same month, the failure-to-file penalty is reduced to 4.5% so the combined total is 5% rather than 5.5% . If both penalties run their full course, the total can reach 47.5% of the original unpaid tax (22.5% for late filing + 25% for late payment) .

Accuracy-Related Penalty

If your return contains a substantial understatement of tax or reflects negligence, the IRS may impose an accuracy-related penalty of 20% of the underpayment . For individuals, an understatement is generally “substantial” if it exceeds the greater of $5,000 or 10% of the tax required to be shown on the return .

Interest: The Silent Compounder

Separate from penalties, interest accrues on any unpaid balance from the original due date—even if you filed an extension . For individuals, the underpayment rate is the federal short-term rate plus 3 percentage points, compounded daily. For the first quarter of 2026, that rate is 7% per year .

At 7%, a $10,000 balance accrues roughly **$725 in interest over twelve months**—and that is before any penalties are added . Unlike penalties, interest generally cannot be abated for reasonable cause; it continues until the balance is paid in full .
