The Wisconsin Tax Bulletin (WTB) is a quarterly newsletter published by the Department of Revenue. It includes information about taxes administered by the department, including income, corporation franchise, sales and use, excise tax, and withholding taxes. Most WTBs are divided into the following sections:
- Articles - Information on tax laws, administrative rules, and return filing requirements
- Report on Litigation - Summaries of Wisconsin tax cases decided by the Wisconsin Tax Appeals Commission and the courts
- Tax Releases - Interpretations of Wisconsin tax laws
- Private Letter Rulings - Written statements that interpret and apply Wisconsin tax laws to a taxpayer's specific set of facts
