How-To Guides: Wisconsin SaaS VAT

Step: 1 Threshold

Effective February 2021, Wisconsin considers vendors who make more than $100,000 in sales in the state in the previous or current calendar year to have economic nexus. (This is an update of Wisconsin’s original economic nexus laws, which went into effect October 1, 2018.) These vendors must collect sales tax from buyers in the state.

 

Economic nexus occurs when gross sales into Wisconsin exceed $100,000 in the previous or current calendar year. If below that threshold, a remote seller generally does not need to register for Wisconsin sales/use tax.

Step: 2 Business Registration

Register with the Wisconsin Department of Revenue (DOR). Use the My Tax Account (MTA) online system to obtain a seller’s permit / sales/use tax account before making taxable sales.

Step: 3 TIN/VAT Number

The issuance of a Wisconsin Sales Tax Account Number (similar to a TIN for sales/use tax purposes) is done by Wisconsin Department of Revenue upon registration.

Step: 1 Standard Rate

Standard Wisconsin sales tax rate is 5% of the sales price. Local county or city taxes may add additional rates (total up to ~5.6% or more in some jurisdictions) based on destination of sale.

Step: 2 VAT Formula

To calculate your tax amount, use the following formula:

 

Tax Amount = Net Price × 5%

Step: 3 Reverse Charge (B2B)

Wisconsin does not use a VAT-style reverse charge for sales/use tax; sellers collect tax when nexus exists. There is no mechanism where the purchaser self-assesses use tax instead of seller collection, except for specific exempt resale situations.

Step: 1 Selling B2C

Taxable sales to private consumers must include the 5% sales tax (plus applicable local rates) on taxable goods or services that are subject to sales/use tax.

Step: 2 Selling B2B

For B2B transactions, if the sold service is taxable digital goods or taxable prewritten software, sales tax must be collected from the business customer. For SaaS treated as a nontaxable data processing service, no tax is collected.

Step: 3 Invoice Requirements

Follow general Wisconsin sales tax invoice practices (state does not prescribe a unique VAT invoice format):

  • Seller Name & Address;
  • Wisconsin Sales Tax Account Number;
  • Invoice Date;
  • Sequential Invoice Number;
  • Customer Name & Address;
  • Description of taxable items/services;
  • Net Price;
  • Taxable Amount;
  • Tax Rate;
  • Tax Amount;
  • Total Due.

Step: 1 Filing Interval

The filing interval is assigned by DOR — typically monthly, quarterly, or annually based on sales volume.

Step: 2 Filing Deadline

Returns and payments are due by the last day of the month following the end of the reporting period; early monthly filers may be due by the 20th of the following month.

Step: 3 Submission

File and pay through My Tax Account (MTA) online portal at Wisconsin DOR. ACH and electronic payment options are supported.

Step: 4 Record Keeping

Maintain sales tax records for at least 4 years from the date of filing for audit purposes.
