Arizona 1099 filing requirements

Arizona participates in the IRS Combined Federal/State Filing program, so 1099s e-filed with the CF/SF election are forwarded by the IRS. Whether the state also wants a direct filing depends on its own rules, summarized below.

What does not change by state

TIN matching, B-Notices, backup withholding and the IRC 6721 penalty are federal. A payee in Arizona who gives you a name/TIN pair that does not match IRS records produces the same CP2100 line as one anywhere else, and the same 15- and 30-business-day clocks. State filing is a separate obligation layered on top.
