IRS CP14 notice: what a balance due letter means and what to do

What a CP14 is

A CP14 is the IRS's first notice that you have an unpaid balance. The IRS says it explains how much you owe and how to pay it. It is usually the first of several letters about the same balance, so it is the easiest point to deal with it.

You might receive one because:

• You filed your return but didn't pay the full amount due

• The IRS corrected a math error or a credit, which created a balance

• A payment you made didn't reach the right year or account

• Penalties or interest were added after filing

The notice number, CP14, appears in the top right corner. If your address is in a federally declared disaster area, the IRS says you should receive a CP14C instead, which reflects the automatic extra time to file and pay.

The parts that matter

Read these lines first:

1. Notice date. Usually near the top.

2. Tax year. Make sure it matches a year you filed.

3. Amount due. Often broken into tax, penalties and interest.

4. Pay-by date. The date the IRS uses for interest and penalties.

5. Contact phone number. In the help section of the notice.

Sample (synthetic): Tax year 2025. Amount you owe: $1,312.40. Pay by November 20 to avoid additional penalty and interest charges.

The IRS doesn't publish a fixed number of days for a CP14. The date that counts is the one on your notice.

Step 1: check that the amount is right

Before paying, compare the notice with your own records:

• Did you make a payment with your return, an extension, or an estimated payment that doesn't appear?

• Was a payment applied to the wrong tax year?

• Does the tax on the notice match the tax on your return?

• If the IRS changed your return, did it send a separate letter explaining the change?

You can view and download the notice in your IRS Online Account, and see your payment history there.

Step 2: if it's correct, pay by the due date

The IRS says that if you pay the full amount by the date on the notice, you won't be charged further interest. After that date, interest builds on the unpaid amount, and a late payment penalty applies if you don't pay in full.

The failure-to-pay penalty is 0.5% of the unpaid tax for each month or part of a month, up to 25% of the unpaid tax, according to the IRS. Interest is also charged on penalties.

Pay through IRS.gov or the methods listed on your notice. Payments go to the United States Treasury, never to a person or a private account.

Step 3: if you can't pay it all, act before the due date

The IRS says to contact it by the payment due date if you can't pay in full. Options it lists include:

• Short-term payment plan. Pay in 180 days or less. The IRS lists a $0 setup fee, though penalties and interest continue until the balance is paid.

• Long-term payment plan (installment agreement). Monthly payments. Individuals can apply online if they owe $50,000 or less in combined tax, penalties and interest and have filed all required returns. Setup fees depend on how you apply and pay. The IRS lists lower fees for applying online and paying by direct debit, and waivers or reductions for low-income taxpayers. Check the current fees on the IRS payment plans page.

• Offer in compromise. For some people who can't pay the full debt.

• Temporary delay of collection. For financial hardship.

The IRS also says that for individuals who filed on time, the failure-to-pay penalty drops to 0.25% per month while an approved payment plan is in place.

Step 4: if you disagree, call

The IRS says to call the phone number in the help section of your notice if you disagree. Have your paperwork ready, such as cancelled checks, bank statements or a copy of your return. Write down the date, the name or ID number of the person you spoke with, and what they told you.

If a phone call doesn't fix it and the problem is causing hardship, the Taxpayer Advocate Service, an independent office within the IRS, may be able to help.

What happens if you do nothing

A CP14 is only the first step. If the balance stays unpaid, interest and penalties keep growing, and later notices become more serious. The IRS failure-to-pay penalty page notes, for example, that the monthly rate rises to 1% if you don't pay within 10 days after a notice of intent to levy. The simplest outcome is to deal with the balance while it is still at the CP14 stage.

Check that it really came from the IRS

The IRS normally makes first contact by mail. Scammers also send fake tax bills. Signs of a fake include pressure to pay immediately, payment by gift card or wire, or a phone number or website that doesn't lead to IRS.gov. To check, search the notice number on IRS.gov or look for it in your IRS Online Account, and call the IRS using a number from IRS.gov rather than one printed on a suspicious letter.

A short checklist

• Notice date and pay-by date on the calendar

• Amount compared with your return and payment records

• Payment made to the United States Treasury, or a payment plan set up

• Any disagreement raised by phone before the due date, with notes kept

• A copy of the notice saved with that year's tax records
