The Wisconsin Department of Revenue's (DOR's) January 2026 tax bulletin outlines a new tax law, income and franchise tax updates, and sales and use tax updates.
The new tax law expands the workforce housing and childcare program portions of the business development credit by adding eligibility for contributions made by a claimant to third parties responsible for building or rehabilitating workforce housing or establishing a childcare program, including contributions made to a local revolving fund loan program.
The bulletin also includes an alert about a rise in cybercriminals targeting tax professionals and accessing their data. Learn the signs of a potential data breach in the tax bulletin.
