Estimated Tax Penalty Notice

Why you might get this

• You didn't make estimated tax payments (payments you send during the year on income that has no tax withheld) when you were supposed to.
• You made your estimated tax payments late.
• You didn't have enough tax withheld from your wages during the year to cover what you owed.
• The total you prepaid through withholding and estimated payments fell short of what the tax rules require.

The deadline

If your notice says you owe a balance, pay the amount by the due date printed on your notice. If you're getting a refund or owe nothing, there's no action you need to take right now. Always go by the exact date shown on your own notice.

This notice doesn't carry a fixed response deadline, but it still deserves attention — see what to do below.

What to do

1. Read your notice carefully. It shows how much you owe and how to pay.
2. If you owe a balance, pay it by the due date printed on your notice.
3. If you can't pay the full amount now, look into other payment options like a payment plan.
4. If you're owed a refund or have no balance, you don't have to do anything at this time.
5. Check whether your penalty can be reduced or removed. This may apply if you or your spouse retired after age 62 or became disabled in the past two years and had a good reason, if most of your tax was withheld early in the year, or if your income came in unevenly during the year.
6. Use the IRS Tax Withholding Estimator to make sure enough tax is being withheld going forward.
7. Consider making estimated tax payments on time next year (generally due April 15, June 15, September 15, and January 15).

What happens if you ignore it

If you owe a balance and don't pay it by the due date on your notice, interest and additional charges can keep adding up over time. If you're owed a refund or owe nothing, ignoring the notice has no penalty, but it's still smart to review it.

You may qualify for free help from the Taxpayer Advocate Service or a Low Income Taxpayer Clinic. You can also authorize someone to represent you before the IRS. If you think the penalty shouldn't apply, review the "Underpayment of Estimated Tax by Individuals Penalty" guidance and ask about reducing or removing it.

The CP30 notice means the IRS charged you a penalty because you didn't prepay enough tax during the year, or you paid late. Each year, you're expected to pay tax as you earn it — either through withholding from your paychecks or by making estimated tax payments (payments you send in yourself on income that isn't taxed automatically).

Start by reading your notice. It explains how much you owe and how to pay it. If a balance is due, pay it by the date printed on your notice. Can't pay it all right now? You can look into a payment plan or other options.

You might be able to get the penalty reduced or removed in certain situations — for example, if you or your spouse retired after age 62 or became disabled recently with a good reason, or if your income arrived unevenly during the year.

Going forward, the IRS Tax Withholding Estimator can help you check that enough is being withheld so you avoid this next year.
