Estimated Tax Penalty FAQs

Common questions about Form 2210 and quarterly tax payments

The IRS estimated tax penalty rate for 2025 is 7% annually (same as the IRS underpayment interest rate). The rate is determined quarterly by the IRS based on the federal short-term rate plus 3 percentage points. The penalty is calculated like interest, compounding daily from each quarterly due date until the tax is paid or April 15.

For tax year 2025, quarterly estimated tax payments are due: Q1 - April 15, 2025; Q2 - June 16, 2025 (June 15 falls on Sunday); Q3 - September 15, 2025; Q4 - January 15, 2026. If a due date falls on a weekend or federal holiday, the deadline moves to the next business day.

You can avoid the estimated tax penalty if you meet ANY of these safe harbors: (1) Pay at least 90% of your current year tax liability; (2) Pay 100% of your prior year tax (shown on last year's return); or (3) If your AGI exceeded $150,000 ($75,000 if married filing separately), pay 110% of prior year tax. Additionally, no penalty applies if you owe less than $1,000.

If your total tax liability minus withholding and credits is less than $1,000, no estimated tax penalty applies regardless of how much you underpaid quarterly. This de minimis exception makes quarterly payments optional for taxpayers with small tax bills.

You generally don't need to file Form 2210 if you qualify for a safe harbor or owe less than $1,000. The IRS can calculate your penalty for you—just leave the penalty line blank on your return. However, you MUST file Form 2210 if you want to use the annualized income method, claim a waiver, or paid estimated taxes unevenly throughout the year.

The annualized income installment method allows you to calculate required payments based on income received in each quarter rather than assuming equal income throughout the year. This is beneficial if your income is seasonal or irregular—like receiving a large bonus in December. Use Schedule AI of Form 2210 to calculate.

Yes. If at least two-thirds (66.67%) of your gross income is from farming or fishing, you only need to pay 66.67% of your current or prior year tax (instead of 90%/100%). You also have the option to make one annual payment by January 15 instead of four quarterly payments. File your return by March 1 to avoid the penalty entirely.

The IRS may waive the penalty in limited circumstances under IRC § 6654(e)(3): (1) The underpayment was due to a casualty, disaster, or other unusual circumstance where imposing the penalty would be against equity and good conscience; or (2) You retired (after age 62) or became disabled during the tax year or prior year, and the underpayment was due to reasonable cause.
