Letter 531 (or 3219): Notice of Deficiency (90-Day Letter)
Definition: Letter 531 (also known as Letter 3219 or CP3219A) is the IRS’s formal Notice of Deficiency, often called the “90-Day Letter.” It details proposed changes to your tax return—increasing your tax liability, reducing a refund, or disallowing credits/deductions—and gives you 90 days (150 days if addressed outside the U.S.) to challenge it in U.S. Tax Court without first paying the tax.
Why It Matters: This is a critical notice: ignoring it makes the IRS assessment final, triggering collections, liens, or levies. It’s commonly issued after audits or unmatched information. If tax disputes feel daunting, you’re not alone—many resolve favorably with proper response. Omni Tax Help analyzes your Notice of Deficiency, evaluates the IRS position, and prepares Tax Court petitions or negotiated settlements to protect your rights and minimize exposure.
Key Details:
- Deficiency Amount: The additional tax (plus interest/penalties) the IRS claims you owe.
- Response Window: File a petition with Tax Court by the deadline (postmark counts).
- No Extensions: The 90-day clock starts from the letter date.
What to Do Next:
- Review enclosed explanations and your records.
- Consult professionals immediately—do not contact the IRS casually.
- Decide: Pay and claim refund, or petition Tax Court.
