What Does Code 290 Mean on Your IRS Transcript?

Code 290 on an IRS transcript is labeled “Additional Tax Assessment,” but it does not always mean you owe more. When the amount next to it is $0.00, the IRS has finished reviewing something on your account and made no change to your tax. When a dollar figure appears, the IRS is adding that amount of tax for that year. In both cases, Code 290 is often the entry that lifts a hold on your account and lets a delayed refund move again.

What a $0.00 Code 290 Means

A Code 290 showing $0.00 is the outcome most taxpayers want to see. It means the IRS completed a pending review and decided no additional tax was warranted. The zero has to be there because the IRS system requires a numerical value for every transaction; the $0.00 satisfies that requirement while confirming nothing changed on your account.¹

Just as important, a zero-dollar Code 290 often works as the mechanism that releases a refund hold. If your transcript previously showed a Code 570 (“Additional Account Action Pending”), which freezes outgoing payments, the $0.00 Code 290 tells the system to lift the freeze so your overpayment can be refunded.² The same logic applies to freezes tied to duplicate returns, math errors, reactivated accounts, and other internal conditions.³

What a Code 290 With a Dollar Amount Means

When Code 290 carries a positive dollar figure, the IRS is assessing additional tax. Common reasons include unreported income the IRS found through third-party records, disallowed credits or deductions after an examination, or corrections to a previously filed amended return. The number next to Code 290 is the extra tax being added for that year, not your total bill.

A non-zero Code 290 also triggers interest, calculated from the original due date of the return through the date the additional tax is paid.⁴ You may see a Transaction Code 196 post shortly after, which records that interest charge.³ A failure-to-pay penalty of 0.5% per month, up to a maximum of 25%, can also apply to any balance that stays unpaid past the due date in the IRS notice. If you set up an approved payment plan, that monthly rate drops to 0.25%.⁵

The underpayment interest rate resets quarterly. For the first quarter of 2026, the rate for individual taxpayers is 7%, and interest compounds daily.⁶ The longer a balance sits, the faster it grows.

If you had a refund coming, the IRS will subtract the additional tax and any interest or penalties from what you were owed. If the assessment is larger than the refund, you will get a notice showing a balance due.

What Happens to Your Refund After Code 290

If your refund was on hold, Code 290 is often the entry that starts things moving again. The IRS system will not release an overpayment while a pending review keeps the account frozen, and a Code 290 resolves that pending status whether the amount is $0.00 or a dollar figure.¹

Once Code 290 posts, watch for Code 846, labeled “Refund of Overpayment.”³ The date next to Code 846 is the day the IRS sends your refund by direct deposit or paper check. Direct deposits generally arrive within a few days of that date; mailed checks take longer.

The gap between Code 290 and Code 846 varies. IRS transcripts update on a weekly cycle, and transactions typically appear within about five days of the cutoff for each cycle.⁷ Straightforward cases may show a refund code one or two cycles after Code 290 posts; complex ones take longer. For real-time status, the IRS recommends using “Where’s My Refund?” rather than reading transcript codes.⁸

Common Reasons You Might See Code 290

Code 290 is a general-purpose adjustment entry the IRS uses to close out pending reviews, finalize audit results, record changes from amended returns, and release freezes.³ A few situations account for most of the entries taxpayers see on their own accounts.

Identity Verification

If your return was flagged for possible identity theft and you verified your identity through the Taxpayer Protection Program, an agent uses Code 290 (usually with $0.00) to close the security hold and let processing continue.⁹

Review of Refundable Credits

The IRS routinely reviews claims for the Earned Income Tax Credit, the Additional Child Tax Credit, and other refundable credits before releasing refunds. Code 290 closes the inquiry when the review is done. A $0.00 amount means the credits were verified as claimed. A positive amount means the IRS reduced or disallowed part of the credit and is adding the difference back to your tax.

Math Error Corrections

If the IRS catches a calculation mistake during processing, it can correct it without a full audit. Code 290 records the resulting change. You will usually receive a CP11 notice if the correction means you owe more, or a CP12 notice if it changed your refund amount.¹⁰

Unreported Income

The IRS compares your return against W-2s, 1099s, and other information returns. When there is a mismatch, the Automated Underreporter program sends a CP2000 notice proposing changes.¹¹ Once the case is resolved, Code 290 posts to finalize the adjustment.¹²

Duplicate Return or Unexpected Payment

When a second return or an unexpected payment posts to an already-filed account, the IRS sets a Code 570 freeze while it works out why the duplicate exists. If no tax change is needed, a Code 290 for $0.00 releases the freeze and lets any overpayment be refunded.¹

If You Think the Assessment Is Wrong

If Code 290 shows an amount you believe is incorrect, your options depend on which notice the IRS sent and how long ago it arrived. The deadlines are strict.

Math Error Notices

Math error adjustments move fast. Instead of a full deficiency notice, you get a CP11, CP12, or similar letter, and you have 60 days from the date of the notice to ask the IRS to reverse the change.¹⁰ If you dispute inside that window, the IRS reverses its adjustment and, if it still wants to pursue the change, must route it through normal examination procedures with full appeal rights.

Administrative Appeal Before Assessment

Before a case reaches the deficiency-notice stage, the IRS usually offers a chance to appeal. The letter proposing the change will give you a deadline, generally 30 days, to request a conference with the IRS Independent Office of Appeals. If the amount in dispute for each tax period is $25,000 or less, you can use the simplified Form 12203 instead of writing a formal protest.¹³

Notice of Deficiency (The 90-Day Letter)

For assessments outside the math error track, the IRS must send a statutory notice of deficiency, sometimes called a “90-day letter,” before it can formally assess the tax.¹⁴ You have 90 days from the mailing date, or 150 days if you are outside the United States, to file a petition with the U.S. Tax Court.¹⁵ Filing a Tax Court petition lets you contest the assessment without paying the disputed tax first. Miss the 90 days and the IRS will assess the tax; you lose the option to go to Tax Court for that assessment.

How to Read Your Transcript

To see Code 290 and the entries around it, pull a tax account transcript through your IRS Online Account at irs.gov. From the dashboard, select “Get Transcript Online” and choose “Tax Account Transcript” for the year in question.¹⁶ If online access does not work, you can request a transcript by mail, which usually arrives in 5 to 10 calendar days.¹⁷

Two other codes are worth locating on the same transcript. Code 570 is the freeze that Code 290 most often releases, so a 570 followed by a 290 is a sign the hold is coming off. Code 846 is the entry that schedules the refund itself; the date next to it is when the IRS sends the money.³ Transcripts update on weekly processing cycles rather than in real time, so for day-to-day tracking the IRS points taxpayers to “Where’s My Refund?” instead.⁸
