Product Taxability: Why Not Everything Is Taxed the Same

The rate is only half the story. What you sell also decides how it is taxed.

September 3, 2026 · 3 min read

Taxability is not universal

Two products at the same address can be taxed differently, because states treat categories like food, clothing, and digital goods in their own ways. The rate is only correct once you know the product is taxable there.

Exemptions are common

Many states exempt or reduce tax on certain essentials, and some exempt specific buyers, such as resellers with a valid certificate. Applying tax where an exemption applies overcharges customers and creates friction.

Digital goods are their own puzzle

Software, downloads, and digital services are taxed inconsistently across states. If you sell digital products, taxability deserves specific attention rather than an assumption.

Classify your catalog

The practical step is knowing the tax category of each product you sell, so the right rule is applied. Getting classification right is what makes the rate right.

Key takeaways

The same address can tax products differently
Exemptions apply to certain goods and buyers
Digital goods are taxed inconsistently by state
Classify each product so the right rule applies
