IRS Letter 525
30-Day Letter After IRS Audit
IRS Letter 525 is a 30-day letter sent after an IRS audit or examination. It means the IRS has completed its review of your return and is proposing one or more changes — typically increasing the amount of tax you owe.
You now have 30 days to agree or appeal before the proposed changes become final.
▸ Why Did I Receive Letter 525?
You likely received this letter because the IRS:
Selected your return for audit
Conducted a correspondence audit (via mail) or in-person audit
Found issues with your deductions, income reporting, or credits
Is proposing additional taxes and/or penalties
The 30-day window gives you time to respond, provide documentation, or request a conference with the IRS Independent Office of Appeals.
▸ What Does Letter 525 Include?
This letter will contain:
A summary of the IRS’s proposed changes to your return
An examination report (Form 4549) explaining the adjustments
Your appeal rights and deadline to respond
Instructions on how to agree or disagree with the findings
- If you do not respond within 30 days, the IRS may issue a Notice of Deficiency (CP3219A), removing your right to appeal before assessment.
▸ What Should You Do?
Review the audit findings carefully. Make sure you understand the proposed changes.
Agree with the IRS? Sign the report and make arrangements to pay any balance.
Disagree? You can submit documentation or request an appeal conference.
Act before the deadline. Waiting too long could result in enforced tax assessments.
