IRS CP3219A — statutory notice of deficiency

A CP3219A is typically a statutory notice of deficiency — often called a 90-day letter. It usually means the IRS proposes a change to tax after third-party information (often after an unresolved CP2000). It is generally not itself a bill or a field audit, and it is not a court decision.

  2. Confirm the date printed on the letter.
  3. Compare proposed changes to your records (W-2s, 1099s, prior return).
  4. Follow the options described on the letter.
