CP3219A Tax Court petition proof: separate the court deadline from the IRS file.

A CP3219A notice can push two tracks at once: working with the IRS and protecting the Tax Court petition deadline. This checklist keeps filing proof, notice dates and evidence in one operational packet.

Direct answer

The Tax Court petition deadline on a CP3219A notice needs its own proof trail; IRS discussions do not safely replace timely petition filing.
