Wisconsin Cottage Food Sales Tax: What's Taxable and What's Exempt

The Seller's Permit Comes First

Before collecting sales tax on anything, register for a Wisconsin Seller's Permit from the Department of Revenue (DOR) if you make taxable retail sales in Wisconsin. Register online through the My Tax Account portal. The one-time Business Tax Registration fee is $20; it is not the refundable security deposit, and renewal is $10 every two years.

If all your sales are exempt, you generally do not need this permit. If you sell any taxable products, register before making those sales.

Which Baked Goods Are Tax-Exempt

Standard grocery items — including unprocessed baked goods — are exempt from Wisconsin sales and use tax. If you sell an unsliced loaf of bread, a bag of cookies, a whole pie, or a dozen muffins as packaged goods for the customer to take home, no sales tax applies.

The exemption covers items sold in their basic form without preparation for immediate consumption. This is the category most home bakers operate in.

When Sales Tax Kicks In

Wisconsin taxes "prepared foods" and "candy" differently from standard groceries:

Prepared foods become taxable when you sell them in a way that suggests immediate consumption. The triggers:

• The food is heated before sale
• You provide eating utensils (plates, forks, napkins, cups)

A cupcake in a sealed bag to take home: tax-exempt. The same cupcake served on a plate with a fork at a market booth: taxable.

Candy has its own definition under Wisconsin law: a preparation of sugar, honey, or other sweetener combined with chocolate, fruit, nuts, or other ingredients, in bar, drop, or piece form. The key: if the item contains flour or requires refrigeration, it's not "candy" for tax purposes — it's a standard bakery product and remains exempt.

So a chocolate bar (no flour) is taxable as candy. A chocolate chip cookie (contains flour) is exempt as a bakery product. This distinction matters for home bakers who make both categories.

The Tax Rate

Wisconsin's base state sales tax rate is 5%. Counties and some municipalities add their own rates on top:

• Milwaukee — combined rate up to 7.9% (highest in the state)
• Madison / Dane County — combined rate of 5.5%
• Most other counties — 5% to 5.5%

You collect tax based on where the transaction occurs, not where you live. If you sell at a farmers market in Madison, you collect 5.5%. If the same customer picks up from your home in a county with no local add-on, you collect 5%.

Filing and Remittance

The DOR assigns your filing frequency based on your expected annual sales tax liability:

• $600/year or less — annual filing
• $601 to $1,200 per quarter — quarterly filing
• $1,201 to $3,600 per quarter — monthly filing
• $3,601 or more per quarter — early monthly filing

Most home cottage food businesses start with annual or quarterly filing. File and remit through the My Tax Account portal by the deadline printed on your return — late filings accrue interest and may trigger penalties.

Keep records of every sale, broken down by taxable and exempt items. You don't need a point-of-sale system — a simple spreadsheet tracking date, item, amount, tax collected, and venue location is sufficient for DOR compliance.

Income Tax Is Separate

Sales tax is what you collect from customers on behalf of the state. Income tax is what you owe on your business profits. These are different obligations.

Report your cottage food business income on your personal federal return (Schedule C) and your Wisconsin individual income tax return. Deductible business expenses include ingredients, packaging, insurance premiums, market booth fees, and your seller's permit fees.
