How to use the checklist
Work through each group and tick items that are done. Items marked critical are those that most often cause assessments or missed claims. Use the first group when buying equipment and materials, the second at year-end for the income or franchise tax return, and the third for the annual property return. Export the list as a PDF for your file.
The manufacturing exemption certificate
Wisconsin exempts machines and processing equipment used exclusively and directly in manufacturing tangible personal property, and materials that become part of products for sale. The buyer documents the exemption by giving the seller a completed exemption certificate, Form S-211. The word exclusively matters: mixed-use equipment may not qualify, and administrative or general building items generally do not. Confirm the current rules with the Department of Revenue.
- Use a blanket certificate for recurring purchases from the same seller
- Keep certificates with the purchase record
- Review mixed-use equipment case by case
Manufacturing credit and property return
The Wisconsin manufacturing and agriculture credit is based on qualified production income and has a rate and limits set by the tax year, so read the current instructions and schedule before computing it. Manufacturing property is assessed by the state, not the municipality, and manufacturers file an annual return on Form M-P by the stated deadline. An accurate fixed asset register with acquisition dates and costs makes this return much easier.
ERP tax-code setup and common mistakes
Set up distinct tax codes for taxable, exempt and use tax accrual purchases, tie them to item categories, and keep certificate references at vendor level. Common errors are applying the exemption to non-qualifying supplies, missing use tax on out-of-state invoices, and a fixed asset register that does not separate manufacturing property. Review the exempt spend report yearly.
