About Form 2210
Form 2210 is used to determine whether you owe a penalty for underpaying your estimated tax during the year and, if so, to figure the amount. The tax system generally expects you to pay tax as you earn income, either through withholding or estimated payments.
If your withholding and estimated payments fall short of what was required, a penalty may apply. The form walks you through tests to see whether you owe a penalty and offers methods, including an annualized income method, that can reduce the penalty when income was uneven during the year.
In many cases the IRS will calculate the penalty for you, so you do not always have to file the form. However, you may want to complete it to check the amount, to request a waiver, or to use the annualized method. Follow the instructions to decide whether filing is necessary.
Who needs to complete it
- Taxpayers who did not have enough tax withheld or paid during the year.
- Self-employed individuals whose estimated payments fell short.
- People with uneven income who want to use the annualized income method.

Frequently asked questions
Do I always have to file Form 2210?
Not always. In many cases the IRS figures the penalty and bills you. You generally file it only if you owe a penalty and an exception, waiver, or the annualized method applies.
How can I reduce the penalty?
If your income was uneven during the year, the annualized income method may lower the penalty. You can also request a waiver in certain situations described in the instructions.
What causes an underpayment penalty?
It generally happens when your total withholding and estimated payments are less than the required amount for the year, meaning you did not pay enough tax as you earned income.
Can I avoid the penalty next year?
Increasing your withholding or making timely estimated tax payments with Form 1040-ES can help you meet the required amount and avoid the penalty in future years.
