What this means for remote sellers
Wisconsin uses a revenue-only economic nexus threshold. You establish nexus once your gross sales into Wisconsin reach $100,000 during current or previous calendar year. The number of separate transactions does not affect the threshold.
How Wisconsin compares to other states
Wisconsin's $100,000 revenue threshold is the most common in the country — 42 jurisdictions use it. It is one of 29 jurisdictions that look at revenue only — the number of transactions does not count. Wisconsin has joined the recent trend of states dropping the separate transaction-count test. Its 5% base sales-tax rate sits below the roughly 5.7% average state rate.
How the Wisconsin threshold is measured
Wisconsin measures the threshold over Current or previous calendar year. Gross sales generally include taxable and (in many states) exempt sales; rules on marketplace-facilitated sales vary. Verify the specifics with the Wisconsin department of revenue.
Do marketplaces collect Wisconsin sales tax?
Wisconsin requires marketplace facilitators — platforms such as Amazon, Etsy, eBay, and Walmart — to collect and remit Wisconsin sales tax on sales made through them. If you sell only through those marketplaces, the platform generally collects the tax for you. Sales you make directly — through your own website or store — still count toward your Wisconsin economic nexus threshold and remain your responsibility. Whether marketplace-facilitated sales also count toward your own threshold varies, so confirm with the Wisconsin Department of Revenue.
What to do if you've crossed it
- Register with the Wisconsin Department of Revenue for a sales-tax permit.
- Begin collecting tax on taxable sales to Wisconsin customers.
- File and remit on the schedule the state assigns.
- Confirm treatment of marketplace sales and any local taxes with a professional.
