Unsure where you owe sales or use tax
Run Your Nexus Risk CheckBusinesses establish economic nexus in Wisconsin once their total sales exceed the state threshold during the measurement period. Once nexus is triggered, the business must register for a sales tax permit and begin collecting sales tax on taxable transactions delivered to customers in Wisconsin.
Marketplace facilitators may collect and remit sales tax on behalf of third party sellers. However, marketplace sales may still count toward the economic nexus threshold in Wisconsin depending on how state rules apply to marketplace transactions.
Remote sellers that trigger economic nexus must register with the Wisconsin Department of Revenue before collecting sales tax. Registration allows the business to obtain a sales tax permit and begin filing returns.
Filing frequency in Wisconsin may be monthly, quarterly, or annually depending on total taxable sales volume. Businesses must file sales tax returns even if no tax is owed during a reporting period.
Businesses that exceed economic nexus thresholds without registering may accumulate unpaid tax liability, penalties, and interest. Monitoring sales thresholds is essential for managing compliance risk.
