Reference library

Practice and Procedure

A working reference on how state and local tax matters actually proceed: notices, deadlines, protests, appeals, audits, collections, and refunds, written jurisdiction by jurisdiction, each stating the law as of its date. This library is drawn from practice, not from a content calendar. The questions come from the founder's practice since 2006: technical issues encountered in the field, worked to resolution at the time, and rewritten here to illustrate real-world application, with every citation re-verified against the law as of each article's date. Articles are drafted and maintained with the assistance of artificial intelligence tools under the founder's direction; the analysis, the positions, and the final review are his.
