Important notices (N-Notice) - 2026

An N-Notice is generally issued to announce a singular event, such as an update to a previously issued tax form or instruction, or to announce a new due date for filing returns and making payments of tax because of a natural disaster. The Department does not revise previously issued N-Notices.

Note: Notices included for 1995 and earlier years are selected sales tax notices only.
