IRS Notice Guide: The First Bill

IRS Notice CP14: What It Means and What to Do by the Due Date

By Ray Neu, Publisher | Last reviewed: October 25, 2026 | Reading time: 8 min

Short answer

A CP14 is the first bill the IRS sends when tax on a return is unpaid. The IRS says to pay the amount owed by the due date printed on the notice, make a payment plan if full payment is not possible, or call if you disagree. Paid in full by that date, the balance draws no further interest, the IRS says.

A CP14 is a bill, not a levy and not a lien filing; the IRS page for the notice mentions neither. This guide covers what the balance is made of, how to check it against your records, the interest rule tied to the printed date, and the options irs.gov lists.

Deadline to know: the controlling date is the one printed on your CP14; the IRS page states no fixed number of days. Separately, 26 U.S.C. § 6601(e)(3) bars further interest when an amount demanded is paid within 21 calendar days of the notice and demand (10 business days if it is $100,000 or more).

What a CP14 notice is and why the IRS sends it

The IRS explanation is one line: “We sent you this notice because you owe money on unpaid taxes.” Publication 594, The IRS Collection Process (Rev. 1-2026), puts the bill at step one of collection: “This is your first bill for tax due.”

The legal basis is 26 U.S.C. § 6303(a). Once a tax is assessed, the IRS must, “as soon as practicable, and within 60 days,” send the person liable a notice “stating the amount and demanding payment thereof.” The IRS lien page calls this bill the “Notice and Demand for Payment.”

Taxpayers whose address of record is in a federally declared disaster area should get a CP14C instead, the IRS says, with extra time to file and pay that applies automatically.

What the balance on a CP14 is made of

Publication 594 says the IRS works from your return: “we will calculate how much tax you owe, plus any interest and penalties.” So the total can have three layers.

Unpaid tax. The tax on the return, or as finally determined, that payments and credits did not cover.
Penalties. Notice 746 (Rev. 7-2026), which the CP14 page lists as related reading, puts the paying-late penalty at ½% of unpaid tax per month or part of a month, capped at 25%. A late return adds a filing-late penalty of 5% per month for up to 5 months, reduced by the paying-late penalty in months when both apply.
Interest. Notice 746 says interest generally runs “from the due date of your return (regardless of extensions)” until paid, and is charged on late-filing and late-payment penalties too. The individual rate is 7% a year, compounded daily, for the quarter that began October 1, 2026 (IR-2026-98).

The monthly charge comes from 26 U.S.C. § 6651(a)(2). The IRS failure-to-pay page adds a timing detail: “We apply full monthly charges, even if you pay your tax in full before the month ends.”

Checking a CP14 against your own records

The IRS says to read the notice carefully, since “It will explain how much you owe and how to pay it.” Before paying or calling, it helps to compare the bill with your own files (these are comparisons, not IRS steps):

The tax year and return type match a return you filed.
Payments you sent for that year appear as credits; the IRS asks callers to have cancelled checks ready.
Any amended return you filed is reflected.
The penalty and interest lines fit the Notice 746 descriptions above.

If something does not match, the CP14 page says to call the number in the IRS Help section of the notice. Publication 594 adds a local IRS office as an option and says that if the IRS agrees, “we will adjust your account and, if necessary, send a revised bill.” For a dispute over whether the tax is owed at all, Publication 594 describes Form 656-L, an offer based on doubt as to liability.

The interest-free window tied to the date on the notice

The IRS answer on interest: “Not if you pay the full amount you owe by the date on the notice. However, interest accrues on the unpaid amount after that date.”

Behind it is § 6601(e)(3): an amount paid within 21 calendar days of the notice and demand (10 business days at $100,000 or more) carries no interest after the notice date, and Notice 746 gives the same time frames. The window looks forward only. Interest that ran from the return due date to the notice date can already be inside the CP14 total.

Partial payment still helps; the IRS says paying what you can by the due date “can reduce interest and penalty charges.” Interest is hard to take off later: Notice 746 says reasonable cause “does not apply to interest,” though related interest falls away when a penalty is removed.

Payment options irs.gov lists for a CP14

Publication 594 says to pay a bill you agree with in full before the due date, or “pay as much as you can.” The CP14 page names three paths beyond that.

Payment plan. Per the IRS payment plans page (updated March 3, 2026), a short-term plan runs 180 days or less with a $0 online setup fee and is available online below $100,000. A long-term installment agreement can be set up online at $50,000 or less with all returns filed; online setup is $29 with direct debit, $69 otherwise.
Hardship delay. “In cases of financial hardship, the IRS may temporarily delay collection until your situation improves,” the CP14 page says. In currently not collectible status the debt “is not forgiven or cancelled” and penalties and interest keep accruing.
Offer in compromise. An offer in compromise may settle a balance for less, but generally not if a plan or asset equity could pay it; the application fee is $205 unless low-income rules apply.

Whichever path fits, the CP14 page says a late payment penalty applies to an unpaid balance and asks taxpayers to “Contact us by your payment’s due date.”

If a CP14 goes unpaid

Publication 594 says “at least one more bill” follows, with interest and penalties continuing, and that after the final bill collection actions “can range from applying your subsequent tax year refunds to tax due (until paid in full) to seizing your property and assets.” It also says an unpaid first bill means “a lien is created by law and attaches to your property.” That legal claim differs from the public Notice of Federal Tax Lien the IRS first warns about on the CP501.

Where the CP14 sits in the notice sequence

Not every account sees every notice; Publication 594 promises only “at least one more bill.” The IRS notices hub compares all five.

CP14: you are here. The opening bill.
CP501: a reminder, and the first notice whose IRS page raises a lien filing.
CP503: the second reminder.
CP504: what the IRS calls a Notice of Intent to Levy.
LT11 or Letter 1058: carries the right to a Collection Due Process hearing before most levies.

Is the CP14 really from the IRS?

The IRS says it normally makes first contact by U.S. mail, so a paper bill is expected. A call, email or text is not from the IRS, it says, if it is unexpected, rushes or threatens you, asks for personal or financial information, or demands payment now.

Find the CP number on the right corner of the letter and confirm it with the IRS notice search on irs.gov.
Check your IRS Online Account, where a genuine CP14 can be viewed.
If the letter does not appear in the search or looks suspicious, the IRS says to call 800-829-1040.

Paper alone is not proof: the IRS warns that “Fraudsters are mailing fake IRS letters to taxpayers.”

When a representative matters for a CP14

The IRS describes online tools for paying or setting up a plan. A representative is another route, for example when the bill is disputed, the balance is above the online plan limits, or several years are unpaid.

Publication 594 says you can be represented by yourself, an attorney, a CPA, an enrolled agent, an immediate family member, or anyone enrolled to practice before the IRS, through Form 2848. For a routine bill the credentials largely overlap; one difference is that the § 7525 practitioner privilege covers only noncriminal tax matters. See attorney vs CPA vs enrolled agent. The CP14 page also points to Low Income Taxpayer Clinics and the Taxpayer Advocate Service.

Frequently Asked Questions

What does a CP14 notice from the IRS mean?

It is the IRS’s first bill for unpaid tax on one of your accounts. The IRS says it was sent “because you owe money on unpaid taxes,” and Publication 594 says the amount includes any interest and penalties figured so far.

How long do I have to pay a CP14?

Until the due date printed on the notice; the IRS CP14 page gives no fixed day count. For interest, § 6601(e)(3) and Notice 746 use 21 calendar days, or 10 business days at $100,000 or more.

Is interest charged on a CP14 balance if I pay on time?

The IRS says no interest is charged if the full amount is paid by the date on the notice. Interest figured from the return due date up to the notice date may already be in the total.

What happens if I ignore a CP14?

Publication 594 says at least one more bill follows, starting with the CP501 reminder in the IRS sequence, while interest and penalties keep accruing.
