What does it mean when a product is tax exempt?

A tax-exempt product is one that a state has specifically decided not to tax. When you sell an exempt product, you don’t charge sales tax on it, even if you have nexus in that state and even if you charge tax on your other products.

Why exemptions exist

States use sales tax exemptions as policy tools. Common reasons:

• Necessities policy: Exempting groceries and prescription drugs reduces the tax burden on lower-income households, since everyone buys food and medicine.
• Industry support: Exempting agricultural equipment, manufacturing inputs, or resale inventory supports specific economic sectors.
• Political compromise: Some exemptions exist because certain industries lobbied effectively. There’s often no pure policy logic behind narrow exemptions.

The result is a patchwork of exemptions that vary significantly by state.

Common product exemptions

Groceries (food for home consumption): Exempt or reduced-rate in roughly 30 states. Taxable at full rate in about 15 states. The definition of “groceries” matters, prepared food is often taxable even in states that exempt unprepared groceries.

Prescription drugs: Exempt in virtually every state. This is one of the most consistent exemptions.

Over-the-counter medications: Exempt in some states, taxable in others.

Clothing and apparel: Fully exempt in Pennsylvania, New Jersey, Minnesota, and a few others. Most states tax clothing. New York has a hybrid, exempt below $110 per item, taxable above.

Agricultural supplies and equipment: Broad exemptions in agricultural states.

Manufacturing equipment and inputs: Many states exempt machinery used directly in manufacturing or materials that become part of the finished product.

Medical devices and equipment: Varying exemptions by state and device type.

Resale inventory: Not really a product exemption: this is a buyer-based exemption. When a business buys goods to resell, they don’t pay sales tax (they’ll collect it when they sell). This requires an exemption certificate.

Exemptions are state-specific

The same product can have entirely different tax treatment across states. A pair of shoes:

• Fully exempt in Pennsylvania
• Taxable in California
• Taxable in Texas
• Exempt below $110 per item in New York, taxable above

This means product taxability isn’t a single setting you configure once, it requires applying the correct rule for each state where you have nexus.

Product exemptions vs. buyer exemptions

Product exemptions apply automatically based on what you’re selling, you don’t need any documentation from the buyer. If you sell apples in a state that exempts unprepared groceries, you don’t charge tax regardless of who’s buying.

Buyer-based exemptions (exemption certificates) are different: these apply based on who the buyer is and why they’re buying. A reseller, a nonprofit, or a government buyer may present an exemption certificate claiming their purchase is exempt. This requires you to collect and validate the certificate.

Getting product taxability right

Miscoding product taxability is one of the most common sources of sales tax errors. A seller who codes food products as fully taxable in exempt states is overcharging customers. A seller who codes taxable digital products as exempt is undercharging and creating remittance liability.

Tax calculation software handles product taxability rules by state when products are assigned the correct product tax codes. The accuracy depends on the initial coding being correct.
