Sales tax for physical retailers
Sales tax is one of the most common compliance failures among new retail business owners — not because it's complicated, but because no one tells you it exists until something goes wrong. You're not keeping that tax money; you're holding it temporarily on behalf of the state. Failing to remit it is the kind of mistake that results in personal liability even inside an LLC.
How sales tax works for a physical retailer
Sales tax is a state-level tax that customers pay on most retail purchases. As a retailer, you collect it at the point of sale and remit it to your state revenue agency — monthly, quarterly, or annually depending on your sales volume. You are a pass-through agent, not the taxpayer. But you are responsible for collecting it correctly and sending it in on time.
Register for a seller's permit. Before you make your first sale, register with your state's department of revenue. This is called a seller's permit, sales tax permit, or resale certificate depending on the state. It's free or low-cost in most states.
Charge the correct rate. Your rate is determined by where the sale happens — typically the location of your store. This includes the state rate plus any local (city/county) rates. Your POS system should handle this automatically once configured correctly.
Track it separately. Keep sales tax collected in a separate line in your books — or better, in a dedicated savings account. It is not your money. Many small business owners get into trouble by treating it as revenue and spending it.
File and remit on schedule. Your state will assign a filing frequency based on your sales volume. New businesses often start at monthly. File on time even if your sales were zero — failure to file (not just failure to pay) generates penalties.
Sales tax is not income — don't spend it
The most common sales tax problem for new retailers: they spend the tax money before the remittance deadline. If you collect $800/month in sales tax and treat it as cash flow, you'll owe $2,400 at the end of the quarter. Keep sales tax in a dedicated account or transfer it weekly. The state will eventually audit you, and unpaid sales tax creates personal liability that pierces LLC protection.

What’s taxable and what’s not
Sales tax rules vary significantly by state — what's taxable in one state may be exempt in another. Common exemptions physical retailers encounter:
Groceries. Most states exempt unprepared food from sales tax. But "unprepared food" has a specific meaning — a raw apple is usually exempt; a hot prepared sandwich from a deli counter usually isn't. If you sell both, your POS must distinguish between them correctly.
Clothing. Some states (including Pennsylvania, New York, and Minnesota) exempt most clothing from sales tax. Others don't. A few exempt clothing below a certain price threshold per item.
Resale exemption. If you purchase items to resell (wholesale inventory), you don't pay sales tax on those purchases — you provide your seller's permit to the wholesaler. This is the resale exemption.
Real-world example
Priya opened a specialty tea shop and didn't realize her state taxed loose-leaf tea differently than prepared tea drinks. She charged no sales tax on anything for 8 months, treating all tea as "groceries." When the state audited her, she owed $3,200 in uncollected tax plus $640 in penalties — which she had to pay personally because she'd already spent the money she should have collected. Her POS was set up correctly once she understood the distinction; the issue was never catching it in the first place.
Sales tax at farmers markets and pop-ups
Market vendors and pop-up sellers often assume they're exempt from sales tax because they're not a permanent store. In most states, that's wrong. If you're selling taxable goods, you owe sales tax regardless of where the sale happens — in a storefront, at a market, or at a craft fair.
Your seller's permit covers sales anywhere in your state. You collect tax at whatever rate applies to the location of the market (which may be different from your home city rate). Some states have a simplified "vendor's" rate for short-term events — check your state's revenue department website.
For food vendors specifically
Most states exempt unprepared food (raw produce, whole baked goods sold to take home) but tax prepared food (hot items, food meant for immediate consumption). If you sell at a farmers market, know your state's definition — it determines whether your sales are taxable. The market organizer often has guidance, but you're responsible for verifying it with the state revenue department.
