How to Get Sales Tax Exemption in Wisconsin: A Complete Guide

If you operate a business or nonprofit organization in Wisconsin, understanding sales tax exemption can save you significant money each year. Many businesses, nonprofits, manufacturers, and resale companies qualify for Wisconsin sales tax exemption but aren’t sure how to apply or what documentation is required. This guide will walk you through the sales tax exemption process in Wisconsin, eligibility requirements, and the steps you need to take to properly claim your exemption.

What Is Sales Tax Exemption in Wisconsin?

Sales tax exemption in Wisconsin allows qualified businesses and organizations to purchase goods and services without paying state sales tax. Instead of paying sales tax at the time of purchase, buyers provide the seller with a Wisconsin Sales and Use Tax Exemption Certificate (Form S-211). This certificate legally tells the seller that the transaction is exempt from Wisconsin sales tax.

Who Qualifies for Wisconsin Sales Tax Exemption?

Not every purchase qualifies for exemption. Wisconsin sales tax exemptions generally apply to:

  • Resellers and wholesalers – If you buy products strictly for resale, you can avoid sales tax by using a resale exemption certificate.

  • Manufacturers – Certain machinery, equipment, and raw materials used in manufacturing may be exempt.

  • Nonprofit organizations – Charities, religious organizations, and educational institutions may qualify.

  • Government agencies – Federal, state, and local government entities are generally exempt.

  • Farming and agriculture – Farmers may qualify for exemptions on items directly used in farming.

How to Apply for Sales Tax Exemption in Wisconsin

To obtain a Wisconsin sales tax exemption, follow these steps:

1. Determine Eligibility

Review the Wisconsin Department of Revenue guidelines to see if your business or organization qualifies for an exemption.

2. Complete Form S-211 (Exemption Certificate)

The Wisconsin Sales and Use Tax Exemption Certificate (Form S-211) is the key document for claiming exemption. You’ll need to include:

  • Buyer’s name and address

  • Seller’s name and address

  • Specific reason for exemption (resale, manufacturing, nonprofit, etc.)

  • Signature and date

3. Provide the Certificate to the Seller

Instead of sending the form to the state, give the completed Form S-211 to the vendor or retailer. This allows you to make sales tax–exempt purchases.

4. Keep Records for Audit Purposes

Maintain copies of all exemption certificates in your files. Wisconsin law requires buyers and sellers to keep exemption documentation in case of an audit.

Common Mistakes When Claiming Wisconsin Sales Tax Exemption

  • Using the wrong exemption reason – Make sure you accurately select resale, manufacturing, or nonprofit status.

  • Failing to renew certificates – While most certificates don’t expire, some vendors may require periodic updates.

  • Misusing exemptions – Only use exemptions for qualified purchases. Misuse could lead to tax assessments and penalties.

Why Sales Tax Exemption Matters for Wisconsin Businesses

Properly managing Wisconsin sales tax exemptions can improve your cash flow, reduce operating costs, and ensure compliance with state tax law. Businesses that fail to claim exemptions correctly may be overpaying sales tax or risk penalties during audits.

Final Thoughts

Obtaining a sales tax exemption in Wisconsin is straightforward if you know the rules and complete Form S-211 accurately. Whether you’re a nonprofit, manufacturer, reseller, or farmer, taking the time to file exemption certificates can save your organization thousands of dollars every year.
