Who sends it: The IRS, by mail, when tax on a return was not fully paid.
What this notice is
A CP14 is usually the first notice the IRS sends when you have unpaid tax. It lists the tax owed plus penalties and interest so far, and asks you to pay by the date printed on it, generally 21 days from the notice date.
If you do nothing, the IRS sends more notices and the amount grows. Later steps can include collection action such as a federal tax lien.
Why you may have gotten it
- Your return showed tax due and you did not pay all of it.
- Tax withheld from a pension, IRA or Social Security did not cover what you owed.
- Your payment was smaller than the balance, arrived late, or was applied to a different tax year.
What to check
- The tax year and the amount.
- Whether you already paid. Look at your bank records for a payment to the IRS or the United States Treasury.
- Your balance and payments in your IRS Online Account, at irs.gov.
- If you did pay, call the number on the notice with the date and amount of your payment ready.
What to do
- Pay in full by the date on the notice if you can, to limit more penalties and interest. Ways to pay, including straight from your bank account, are listed at irs.gov.
- If you cannot pay it all, ask for a payment plan, online at irs.gov or by calling the number on the notice. Interest and some penalties continue during a plan, but it helps you avoid further collection action.
- If paying would leave you unable to cover basic living costs, say so when you call. The IRS has other options for people in hardship.
- If you disagree with the amount, call the number on the notice with your records ready.
How to tell a real one from a fake
A real CP14 comes by mail, shows CP14 on the page, and asks you to pay the United States Treasury. Check your balance yourself in your IRS Online Account or by calling 1-800-829-1040.
The IRS does not call demanding immediate payment by gift card, prepaid card, wire or crypto, and does not threaten to have you arrested. A caller who does either is not the IRS.
Who can help
A tax preparer can help you compare payment choices. If the debt is causing real hardship or you cannot get it fixed, the Taxpayer Advocate Service is free and independent from the rest of the IRS.
