ما هو IRS Notice؟

Common IRS notices include: CP2000 (proposed changes based on third-party information mismatches — most common notice), CP501/CP503/CP504 (balance due notices in escalating severity), CP90/LT11 (final notice of intent to levy), LT16 (return delinquency), and audit notification letters (various). The response deadline is typically 30–60 days and is strictly enforced — missing it forfeits your right to contest. Not all notices require immediate payment: many are informational, propose adjustments you can contest, or request documentation. The CP2000 is especially important — it proposes changes based on W-2, 1099, or other information the IRS received that doesn't match your return, but the proposed amount often overstates liability before deductions are factored in. Notices are sent by postal mail to your last known address; they do not arrive by email or phone. Any 'IRS agent' calling by phone is a scam.

IRS notices are time-sensitive — missing response deadlines can result in automatic assessments, loss of appeal rights, and aggressive collection action. A tax advisor or enrolled agent can interpret the notice, determine if you actually owe what is claimed, prepare a response, and represent you before the IRS if needed.
