Code 290 on an IRS Transcript: What "Additional Tax Assessed" Means in 2026

By Angeline Balsitis, EA · Reviewed by Melissa Ly, Chief Tax Officer · Published November 14, 2025 · Updated November 4, 2026 · Editorial Standards

You were scrolling your account transcript, checking on a delayed refund or a CP2000 you answered months ago. A new line appeared: "290 Additional tax assessed." That line is the moment an IRS review stops being a question and becomes an official number. It is either the best line on the page ($0.00) or the start of a bill, and which one you are looking at changes everything you do next.

This guide covers both versions, what the date beside the code controls, whether a 290 is bad news, when a refund follows it, and how to challenge one that is wrong. The image below shows where the 290 line sits on a real account transcript and how to read the amount and date beside it.

What does code 290 mean on an IRS transcript?

Clarity Tax Relief explains code 290 to clients as the IRS making an assessment official. Code 290 means the IRS posted an additional tax assessment to your account for that tax year. IRS Document 6209, Section 8A, the manual that defines every transcript code, titles TC 290 "Additional Tax Assessment" and describes it as "additional tax as a result of an adjustment to a module which contains a TC 150 transaction" (your filed return). When the amount is $0.00, the same entry is used to close a case or release a hold with no tax added. The dollar figure beside it, and the codes around it, tell you which of those happened.

People search this as "290 code IRS," "290 tax code," or "tax code 290," and the wording trips some readers up: there is no Section 290 of the Internal Revenue Code at work here. It is a three-digit transaction code on the account transcript, the same family as code 150 and code 570. Our IRS transcript codes reference lists the full set.

Code 290 is the transaction code the IRS uses to make an assessment official. Your account transcript is a ledger: code 150 records the tax from the return you filed, and a 290 records tax the IRS added after that. "Additional" is relative to the return, not to anything you owed before. (If transcript layout is new to you, our guide on how to read an IRS account transcript covers the full ledger. This page stays on the 290 line itself.)

Code 290 has a mirror image. Code 291 is "tax reduced," the entry that posts when an assessment is abated, which is why a wrong 290 is worth disputing rather than absorbing.

What is the difference between a code 290 for $0.00 and one with a dollar amount?

A 290 for $0.00 is a closing entry. The IRS opened some kind of review, a refund hold, an underreporter screen, an identity or income check, and needed a formal transaction to close it. Zero dollars means the review ended with no change to your tax. If your refund was stuck behind a code 570 hold, a $0.00 290 is frequently the entry that releases it. Document 6209 lists the freezes a TC 290 releases, and the list includes the refund hold (-K), the 570 hold (-R), the duplicate return freeze (-A) and the math error freeze (-G). That is why a 290 with no money attached so often shows up right before a refund moves.

“A 290 for zero dollars usually means the IRS looked and walked away. A 290 with a number is a bill, and interest on it runs from the date printed beside it,” says Angeline Balsitis, EA, an IRS Enrolled Agent at Clarity Tax Relief.

One narrower case: if you asked for penalty relief and a $0.00 290 appeared with no refund involved, the IRS may have used the entry to close that request. The letter that follows, marked by a 971, says whether the penalty was removed; if it was, a code 277 (penalty abated) posts too. If no 277 appears, read the letter for the denial and your appeal rights.

A 290 with a dollar amount is a new debt. The IRS has formally assessed that much additional tax against you, interest began accruing as of the date on the line, and collection treats it like any unpaid balance. You will usually see companion entries nearby: code 196 for interest assessed, code 276 for the failure-to-pay penalty, and a 971 marking the letter that explains it.

Is code 290 on a transcript bad?

It depends entirely on the amount. A $0.00 290 is neutral to good: the IRS looked at something and changed nothing, and if a refund was frozen this is often the entry right before it moves. A 290 with a dollar amount is a bill, and one that is already accruing interest. It is not an audit indicator (a full examination shows as code 420). It is not a penalty by itself. The penalties post as their own codes. The one case where a $0.00 290 deserves attention is when a 971 sits beside it, because that means an explanation letter is on its way and it is worth reading.

“The income or payment information we received from third parties, such as employers or financial institutions, doesn't match what you reported on your tax return. This difference may increase or decrease your tax or may not change it at all.”

Why did a code 290 post to your account?

Clarity Tax Relief starts every 290 review with the codes posted around it. Most dollar-amount 290s come from a document-matching or correction process, not from a person deciding to bill you. The codes around the 290 usually tell you which process it was. The image further down shows what these entries look like in sequence on an actual transcript.

Three IRS programs produce nearly all of them: the math error unit that corrects arithmetic and missing forms during processing, the Automated Underreporter program that matches W-2s and 1099s against your return and sends the CP2000, and Examination. Each closes hundreds of thousands of cases a year, and each ends in the same transaction code when tax is added.

A 290 can come from any of those, which is the reason the code on its own tells you so little. It records that an assessment posted, not why.

The single most common source of a surprise dollar-amount 290 is the Automated Underreporter program, the computer that matches W-2s and 1099s against your return. If a code 922 underreporter review appears earlier in the year's history and you never resolved the CP2000 notice that followed, the 290 is that proposed amount becoming real.

The IRS says a CP2000 that goes unanswered leads to "another notice and a bill"; in practice that is the CP3219A, a Statutory Notice of Deficiency with a 90-day window to petition the Tax Court, and the 290 posts once that window closes without a petition. On a joint return this often traces to one spouse's income, a side 1099, a brokerage form, a retirement distribution, that the other spouse never saw. The assessment binds you both: each spouse is fully liable for the whole amount, though innocent spouse relief may exist where one spouse hid the income.

Which codes travel with a 290, and what does Document 6209 say each one means?

Document 6209 Section 8A is the IRS's own dictionary of transaction codes. The entries below are the ones that most often sit near a 290. Reading them together is how you tell a closed review from a new bill.

Why does code 290 show a future date, and what does the date control?

Do not panic if the date is in the future. Transcripts post on weekly cycles, and a 290's date is routinely one to three weeks ahead of the day it first appears. It is the effective date of the assessment, not a deadline you are already missing.

That date is the legal assessment date, the day the debt officially exists, and three separate clocks hang on it. First, interest is computed to that date and compounds daily after it, so the transcript figure is a snapshot that grows. The IRS underpayment rate for the quarter beginning October 1, 2026 is 7%, the same as the prior quarter. Second, the failure-to-pay penalty (0.5% of the unpaid tax per month or part of a month, capped at 25%) starts stacking on any unpaid portion; it drops to 0.25% per month while an approved payment plan is in place. Third, the assessment date starts the 10-year collection statute (CSED) for that specific amount, separate from the CSED on the original code 150 tax. A 2022 tax year with a 290 assessed in 2026 is collectible on that added amount until roughly 2036, longer if tolling events pause the clock.

How long after code 290 will I get my refund?

If the 290 is $0.00 and it closed the hold on your refund, the next entry to watch for is code 846, refund issued. The date beside the 846 is the date the money is sent. The IRS does not publish a day count between the two entries. In practice the 846 tends to post within the next one or two weekly cycles. There is nothing you need to send to make it happen. If the 290 carries a dollar amount, it is applied against any refund on the account first. When the assessment is smaller than the refund, the reduced refund still issues. When it is larger, the refund disappears and a balance-due notice follows for the difference.

What notice follows a code 290, and what clock does each one set?

Every dollar-amount 290 produces mail, and the transcript's code 971, notice issued entry tells you when it went out. A balance you ignore enters the same automated collection sequence as any unpaid tax bill. The interest meter started on the assessment date, not the day you noticed the entry:

None of this needs a person to touch your file. The practical point cuts both ways: act early if the 290 is right, and start the paper trail early if it is wrong, because a correction takes longer than an escalation does.

How do you dispute a code 290 assessment that is wrong?

Clarity Tax Relief sorts a disputed 290 by how it was assessed before picking a route. The route depends on how it was assessed, and the codes around the 290 tell you which. A CP2000-based 290 (after a 922) can be reopened through underreporter reconsideration if you can document that the matched income was already reported, was nontaxable, or belongs to someone else. An exam-based 290 (after a 420 or 424) goes through audit reconsideration. A plain error, wrong year, doubled income, missed cost basis, is fixed with Form 1040-X. A win posts as code 291 reducing the balance, and the related interest and penalty come off with it. Keep making arrangements on the balance while you dispute; interest does not pause for a pending reconsideration.

Say a joint return left off one spouse's consulting 1099, the CP2000 went unanswered during a move. The transcript now shows a 290 for $22,000 of tax plus a 20% accuracy-related penalty of $4,400 and about $1,100 of interest, $27,500 in all. Both spouses owe the full amount. Before agreeing to any of it, check the return: if $8,000 of that 1099 income was actually reported on a Schedule C under the business name, reconsideration with the matching records takes the tax on it, the penalty on that tax and the related interest off the account with a code 291. That is the anatomy of most 290 cases we see: part payable, part disputable.

What are your options when code 290 adds tax you can't pay?

• Pay in full. Stops interest and penalty accrual immediately. If you can raise the money within six months, a short-term plan (up to 180 days, $0 setup fee, available when you owe under $100,000 in combined tax, penalties and interest) buys the time without a formal agreement.
• Monthly installment agreement. Balances of $50,000 or less in combined tax, penalties and interest qualify for an online long-term agreement without financial statements; the setup fee is $29 by direct debit or $69 otherwise. Interest and the failure-to-pay penalty continue while you pay (the penalty rate drops to 0.25% a month on an approved plan), so faster is cheaper. Run your own numbers in the IRS payment plan calculator to see what a monthly amount does to the total. On the $27,500 example above, $27,500 ÷ 72 is about $382 a month as a base figure, and paying $500 to $600 a month retires it years sooner. Here is how to set up an IRS payment plan online.
• Penalty relief. If the 290 dragged failure-to-pay penalties with it and your prior three years are clean, first-time penalty abatement can remove qualifying penalties. The accuracy-related penalty is not covered by it and has to be contested on reasonable cause. Estimate what penalties and interest are adding with the IRS penalty & interest calculator.
• Hardship. If paying anything would leave you unable to cover basic living expenses, Currently Not Collectible status pauses collection while the debt and interest remain. An Offer in Compromise is means-tested and fits only when your income and assets cannot cover the debt before the CSED.

How to respond to a code 290, step by step

1. Read the amount. A $0.00 290 closed a review with no tax added. A dollar amount is a new assessment, with interest running from the date beside it.
2. Read the codes around it. A 922 earlier means a CP2000 case; a 420 or 424 means an exam; a 976 or 977 means your own amended return; a 971 marks the letter that explains it.
3. Match the 971 date to the letter in your mail. The pay-by or petition date printed on that notice is the one that controls.
4. Compare the assessment to your return and your W-2s and 1099s. If the matched income was already reported, nontaxable, or someone else's, start underreporter reconsideration, audit reconsideration, or Form 1040-X, depending on how it was assessed.
5. Arrange the balance while any dispute runs. Pay in full, take a short-term plan, or set up an installment agreement. Interest does not pause for a pending reconsideration.
6. Watch for a 291. A successful dispute posts as code 291, with the related 197 and 277 taking the interest and penalty off.

Common code 290 mistakes

• Panicking over a future date. A 290's date routinely sits one to three weeks ahead of the day it appears. It is the effective assessment date, not a deadline you missed.
• Treating a $0.00 290 as a bill. It is a closing entry, and if a refund was on hold it is often the line right before the 846.
• Absorbing a wrong assessment. Part payable, part disputable is the usual shape. A win posts as a 291.
• Pausing payments during a dispute. Interest and the 0.5%-per-month penalty keep accruing while reconsideration is pending, and the penalty rises to 1% per month if you do not pay within 10 days of a notice of intent to levy.

Can you handle a code 290 yourself, or does help change the outcome?

Clarity Tax Relief will tell you when a 290 needs no help at all, and plenty of them don't. One number is worth having before anyone pitches you a settlement: Clarity Tax Relief's analysis of the 2025 IRS Data Book found the IRS accepted 5,464 of 38,797 offers in compromise in fiscal 2025, about 1 in 7 (see the full breakdown). A $0.00 290 requires nothing from you; it is the IRS closing its own file. A dollar-amount 290 you recognize and agree with, your own amended return posting or 1099 income you forgot, paired with a balance you can pay within 180 days or cover on a simple online plan, is a do-it-yourself fix, and so is a first-time abatement request on a clean three-year history.

Experienced help changes the outcome in a narrower set of cases: you do not recognize the income behind the assessment, the 290 sits on top of multiple unresolved years, exam codes and appeal deadlines are in play, the assessment traces to a spouse's hidden income on a joint return, or a CP504 or LT11 has already arrived and the dispute has to run alongside a levy defense. In those cases the order of operations, dispute, then penalties, then payment terms, determines what you ultimately pay. If a dispute stalls and it is causing hardship, the Taxpayer Advocate Service is a free, independent escalation path inside the IRS.

Terms on your transcript, decoded

• Transaction code: the three-digit number that identifies each entry on an account transcript. 150 is the return, 290 is additional tax assessed, 291 is tax reduced, 971 is a notice issued.
• Assessment date: the date beside the 290. Interest is computed to it and the collection statute runs from it.
• CSED: Collection Statute Expiration Date, generally 10 years after each assessment, pausable by offers, bankruptcy and appeals.
• Cycle date: the weekly IRS processing batch a transaction posted in, which is why 290 dates often sit a couple of weeks in the future.

The bottom line on code 290

Code 290 is the IRS making an assessment official. For $0.00 it means a review closed with nothing added; with a dollar amount it is a new debt accruing interest from the date beside it, and the letter marked by the nearby 971 carries the deadline that counts. Read the companion codes to learn where it came from, dispute the part that is wrong through the matching route, and put the rest on a payment path before the notice sequence moves toward a levy.
