Yes, pet food is taxable in almost every U.S. state. Most states that exempt groceries from sales tax define food as something sold for human consumption, so a bag of dog or cat food gets rung up at the standard sales tax rate for tangible goods. Depending on where you shop, that means anywhere from zero to more than 10% added at checkout, with a national average close to 7.5%.
Why the Grocery Exemption Doesn’t Cover Pet Food
Roughly 37 states and Washington, D.C. exempt unprepared groceries from sales tax. The catch is how “food” is defined. Under the framework most states follow, food and food ingredients means substances “sold for ingestion or chewing by humans and consumed for their taste or nutritional value.”1Streamlined Sales Tax Governing Board. Food Definition Issues Pet food is marketed and labeled for animals, so it falls outside the definition. Even ordinary produce like apples or carrots loses the exemption once the seller knows the buyer intends it for a horse rather than a person.
That’s why the same shopping trip can produce a tax-free receipt for your cereal and a taxed line for the dog food underneath it. Many states also exempt feed for livestock, but those exemptions exist to support agricultural production, not to help with household pets.
How Much Sales Tax You’ll Pay on Pet Food
The amount depends entirely on where you buy. Combined state and local sales tax rates range from zero to over 10%, with a population-weighted national average of about 7.53% as of 2026.2Tax Foundation. State and Local Sales Tax Rates, 2026 On a $50 bag of premium food, that’s anywhere from nothing to roughly $5 in tax.
Five states impose no statewide sales tax: Alaska, Delaware, Montana, New Hampshire, and Oregon. Pet food purchases in those states generally won’t include state sales tax, though some Alaska localities levy their own. Every other state applies its standard rate for tangible goods. A handful of states tax human groceries at a reduced rate, but pet food usually stays at the full rate even there.
Exemptions That May Apply
The general rule is taxable, but a few narrow exceptions exist. They won’t help most pet owners, and each one has specific conditions.
Food for Certified Service Animals
Some states exempt food purchased for certified service animals, typically guide dogs for people who are blind or have other qualifying disabilities. The buyer usually needs a state-issued exemption certificate to present to the retailer. Not every state offers this exemption, and where it exists, the qualifying conditions are narrow. Emotional support animals and pets registered through online services generally don’t qualify.
Nonprofit Shelters and Rescues
Qualifying 501(c)(3) organizations, including animal shelters and rescue groups, can often buy supplies tax-free in states that grant sales tax exempt status to nonprofits. The organization applies to the state tax department, receives an exemption certificate, and presents it to retailers when buying on the group’s behalf. Personal purchases by employees or volunteers don’t qualify, even if the organization later reimburses them. A shelter that buys food tax-free may still have to collect sales tax on items it sells, depending on state law.
Veterinary Prescription Diets
Therapeutic pet foods occupy a gray area between food and medicine. The FDA considers a pet food product a drug rather than a food when its intended use is to treat or prevent a disease and that effect isn’t derived mainly from nutrition, taste, or aroma.3U.S. Food and Drug Administration. FDA’s Regulation of Pet Food A diet formulated to acidify a cat’s urine for urinary tract health, for example, falls into the drug category under FDA guidance.
Some states treat veterinarian-dispensed therapeutic diets the way they treat prescription medications, meaning no sales tax. The exemption typically requires the food to be prescribed by a licensed veterinarian for a diagnosed condition and dispensed through the veterinary practice rather than sold off the shelf. A “sensitive stomach” formula grabbed off a pet store aisle almost certainly won’t qualify, even if the same brand appears in a vet’s office.
Ordering Online Doesn’t Avoid the Tax
Buying pet food online won’t skip the sales tax. Since the Supreme Court’s 2018 decision in South Dakota v. Wayfair, states can require online retailers to collect sales tax even when the seller has no physical presence in the buyer’s state.4Supreme Court of the United States. South Dakota v. Wayfair, Inc. (No. 17-494) Nearly all states with a sales tax have since adopted economic nexus rules, and most large online sellers and marketplaces now calculate tax based on your shipping address at checkout.
When the seller doesn’t collect the tax, the obligation shifts to you as use tax. Use tax exists in every state with a sales tax and applies at the same rate: you owe what you would have paid buying locally. Most consumers run into this with small out-of-state sellers below the economic nexus threshold or sellers based in no-sales-tax states. Many states let you report and pay use tax on a line of your annual state income tax return. The amounts on pet food are usually small, but the obligation is real, and states have grown more aggressive about enforcement as online shopping has expanded.
Penalties for Claiming an Exemption You Don’t Qualify For
Presenting a fraudulent exemption certificate to skip sales tax on pet food is treated like any other form of tax evasion. Civil penalties include repayment of the tax plus interest and additional fines, and intentional fraud can escalate to criminal charges. The penalties are designed to far exceed whatever tax the buyer was trying to avoid, which for pet food is rarely more than a few dollars per purchase. If an exemption clearly fits your situation, use it. If it doesn’t, pay the tax.
