IRS Tax Review Code 1242 Explained: Everything You Need to Know
Many people see this code alongside Tax Topic 151. It looks scary at first.
In most cases, it’s just a refund review. The IRS may want more time, or a few extra documents, before releasing your money.
This guide breaks down IRS Reference Number 1242 in plain terms. You’ll learn what it means, how long it takes, and what to do next.
IRS Reference Number 1242: Quick Meaning
IRS Reference Number 1242 means the IRS is reviewing your tax return before sending your refund.
They may be checking your income, tax credits, identity, or supporting documents. This review doesn’t always mean something is wrong.
Often, the IRS just needs extra time to verify your information.
What Does IRS Reference Number 1242 Mean?
Your refund is on hold while the IRS double-checks some details on your return.
This can happen for several reasons:
- Wrong income numbers
- Missing tax forms
- Large tax credits claimed
- Identity checks
- Random review selection
- A big change in income from last year
The IRS uses automated systems to flag mismatches. If something doesn’t line up, your refund gets held for review.
This code doesn’t mean fraud. It doesn’t mean an audit either. Most of the time, it simply means the IRS needs more time to check your numbers.
Why Your Tax Return May Be Under Review
The IRS reviews return when something doesn’t match its records. It’s not automatically a red flag; it’s just a confirmation step.
Income Doesn’t Match
Your employer reports your income directly to the IRS. If your return shows a different number, your refund may get held for review.
Large Tax Credits
Claims like the Earned Income Tax Credit, Child Tax Credit, or education credits get extra scrutiny. The IRS checks to confirm you actually qualify.
Missing Forms
Sometimes the IRS never receives all your paperwork — W-2s, 1099 forms, or business income records. Missing documents can trigger a delay.
Identity Checks
The IRS verifies identity to stop fraudulent returns filed under someone else’s name or Social Security number.
Random Selection
Some returns are simply chosen at random. It can happen to anyone, and it doesn’t imply a problem.
What Do Tax Topic 151 and Reference 1242 Mean Together?
Tax Topic 151 relates to your appeal rights if the IRS changes, reduces, or denies part of your refund.
Paired with Reference Number 1242, it usually signals a review in progress — and possibly an adjustment you have the right to challenge.
- Your refund is under review
- The IRS needs more time
- Documents may be requested
- Your refund amount could change
This doesn’t mean you’ll lose your refund. Many people still receive the full amount once the review wraps up. Others get a smaller refund if the IRS adjusts a figure.
CP05, CP05A, and CP05B Notices Explained
The IRS sends specific letters during a review. Each one means something slightly different.
CP05 Notice — The IRS is checking your return and your refund is on hold. Usually, they’ll tell you to simply wait. This is common during a 1242 review and isn’t necessarily a red flag.
CP05A Notice — The IRS needs more documents. This might mean pay stubs, W-2 forms, bank statements, or employer letters. Send what’s requested quickly to avoid further delays.
CP05B Notice — The IRS found an income mismatch against records from employers, banks, or other payers. Your refund stays on hold until you provide the requested information.
How Long Does IRS Reference Number 1242 Take?
Timelines vary. Some people get their refund in 2 to 4 weeks.
In many cases, the IRS asks taxpayers to allow up to 60 days. Some reviews take longer than that.
A few factors affect the timeline:
- The type of review being conducted
- Whether documents are missing
- IRS workload, especially during tax season
- How fast you respond if they request information
Quick replies help, but the IRS still needs time to review everything carefully.
Should You Call the IRS About Reference Number 1242?
Yes, you can call. It may help you understand your refund status or confirm what the IRS still needs.
Consider calling if:
- You’ve received a notice
- The IRS has asked for documents
- More than 60 days have passed with no update
- Your refund status hasn’t changed in a while
Before calling, have these ready: your Social Security number, a copy of your return, any IRS notice, bank details, and your filing status. This helps the representative find your case faster.
Ask simple questions: what the review covers, whether documents are needed, and roughly when it might finish. Stay calm and patient — IRS phone lines run busy, especially during tax season.
What Documents Might the IRS Ask For?
Requests are routine during a review. The IRS uses these to confirm your information and process your refund safely.
Income proof — W-2s, 1099s, or pay stubs confirming what you earned.
Identity proof — A driver’s license, state ID, or passport confirming it’s really you filing.
Tax credit proof — Birth certificates, school records, or medical records supporting credits you claimed.
Bank information — Statements or direct deposit details to confirm your refund lands in the right account.
Business records — Invoices, receipts, or profit records if you own a business.
Send clear, readable copies. Never mail original documents unless the IRS specifically asks for them.
IRS Review vs. Audit vs. Appeal
These three terms get mixed up often, but they’re different processes.
Process | What It Means | What the IRS Checks | Is It Serious? |
IRS Review | A basic check of your return | Income, credits, tax forms | Usually not serious |
IRS Audit | A detailed investigation | Income, expenses, deductions, records | More serious |
IRS Appeal | A request to reconsider a decision | IRS decisions and tax changes | Formal process |
IRS Review — The most common process. Computers usually run the checks, verifying numbers, credits, and forms. Reference Number 1242 falls into this category.
IRS Audit — More serious than a review. The IRS examines income, expenses, deductions, and bank records closely. Some happen by mail, others require meetings. An audit isn’t automatically fraud, but it does mean a deeper look.
IRS Appeal — Used when you disagree with an IRS decision, like a reduced refund or denied credit. It’s a formal process that may take time and require supporting documents.
Bottom line: Reference Number 1242 usually means a refund review, not a full audit.
Can You Speed Up an IRS 1242 Review?
There’s no shortcut, but you can avoid extra delays.
- Reply fast. Waiting too long on document requests only slows things further.
- Send correct information. Double-check everything before submitting to avoid follow-up questions.
- Keep copies. Save every form and letter you send, in case questions come up later.
- Use tracking. If mailing documents, track delivery so you have proof they arrived.
- Stay patient. Reviews take longer during busy tax season. Check your status online and respond quickly to notices.
How to Avoid an IRS Refund Review Next Year
You can’t prevent every review, but careful filing lowers your risk. Accurate tax filing helps the IRS process your return faster.
File accurate returns
Double-check your name, Social Security number, income, and bank details before submitting.
Report all income
Include every W-2 and 1099 you received. Missing income is a common trigger for review.
Claim correct credits
Only claim credits you actually qualify for, especially EITC and Child Tax Credit.
File early
Early filing reduces mistakes and lowers your risk of identity theft.
Keep good records
Save receipts, forms, and income records in case questions come up later.
Use trusted tax software
Good software catches errors before you file and calculates credits correctly.
Conclusion
IRS Reference Number 1242 sounds alarming, but it’s usually a straightforward review — not proof something’s wrong.
Respond promptly if the IRS requests documents. Keep good records and file accurately, and the process gets smoother each year.
Most people still get their refund once the review finishes. Stay calm, follow IRS instructions, and give it time.
