DOR issues proposed guidance for one-time audit relief

January 17, 2020

The Wisconsin Department of Revenue (DOR) is accepting comments on its proposed guidance for a one-time audit relief provided under Act 10.

The one-time reduction is equal to 10% of additional sales tax imposed for each year of the audit period if the annual gross sales of the audited taxpayer are less than $5 million for each year of the audit. The one-time reduction only applies to the additional 5% state sales tax.

The DOR determines the one-time reduction separately for each year of the audit period. If the taxpayer’s gross sales are $5 million or more in one year, he or she can still receive a reduction in the other years of the audit period if their gross sales are less than $5 million.
