Tax preparation License Requirements in Milwaukee, WI

Tax preparation is a federally regulated profession under 26 U.S.C. § 330 and IRS Circular 230.

The PTIN requirement applies to anyone who prepares, assists in preparing, or supervises the preparation of any federal tax return or refund claim (26 U.S.C. § 330).

Tax preparers must comply with comprehensive standards established in IRS Circular 230, which governs ethical conduct, tax return preparation standards, and record-keeping requirements.
