On the paper
Find the balance, the tax year, and the payment date printed on your copy, then compare the tax year and the amount against the return you filed and any payment you already made.
Look at the line that breaks the balance into tax, penalty, and interest. A CP14 whose tax line matches your return and whose balance is nearly all penalty and interest is a different problem from one whose tax line is larger than the tax you reported. The first is a payment and penalty question. The second means the IRS posted something you did not report, and the notice will name the adjustment.
Find the date printed on your notice or letter. The paper notice and the current official IRS instructions control, even where this page differs.
Where this notice comes from
CP14 is the notice and demand for payment the Internal Revenue Code requires before the collection sequence can move. It usually arrives a few weeks after a return is processed, or after the IRS assesses tax from a math change or an examination that closed.
If the balance stays unpaid, the reminders that follow are CP501 and CP503, then CP504, and eventually a final notice such as LT11 or Letter 1058. Each of those steps carries different rights. CP14 carries none of them beyond the ordinary right to pay, to dispute the assessment through the channels the notice names, or to ask about a collection alternative.
Penalties and interest run on their own schedule regardless of which notice is in the mail. That is why the tax, penalty, and interest breakdown on the paper is worth reading before deciding what to do.
General next steps
- Match the tax year and the tax figure on the notice to your filed return.
- If the tax figure matches, decide between paying in full, paying part, or asking the IRS about a payment plan through the options linked below.
- If the tax figure does not match, use the response instructions printed on your notice and keep a copy of everything you send.
Timing
The interest rule comes from 26 U.S.C. section 6601(e)(3), checked on uscode.house.gov on September 10, 2026. The IRS page for this notice states no general number of days and points to the due date on your copy. The date printed on the notice controls; do not calculate a deadline from this page.
What CP14 does not mean
CP14 is not an audit, and it is not a levy. Nothing about it says the IRS has examined the return or questioned any item on it. It also does not mean the balance is correct. The IRS sends CP14 from what its computer posted, which can include a payment credited to the wrong year or a return the IRS keyed differently from the way you filed it.

Common questions
Does interest keep running after I get a CP14?
Yes. Interest runs on an unpaid balance until it is paid. Under 26 U.S.C. section 6601(e)(3), paying the full amount within 21 calendar days after the notice and demand, or 10 business days if the amount is $100,000 or more, keeps interest from being imposed for the period after the notice date.
The CP14 shows a payment I made as missing. What now?
Gather the proof: the cancelled check, the confirmation number, or the bank record, and the tax year you told the IRS to apply it to. Payments applied to the wrong year are a common cause of a CP14 on a year you believed was closed. The notice names the contact method the IRS wants for that correction.
Can I get the penalty removed if I pay the tax?
Paying the tax does not remove a penalty by itself. Penalty relief is a separate request with its own standards, and the IRS decides it on the facts of the year in question. Paying the tax does stop the failure-to-pay penalty from growing on the amount paid.
