US Sales Tax: The Most Complex in the World
The United States has no federal sales tax. Instead, 45 states (plus Washington D.C.) levy their own sales taxes, each with different rates, rules, and exemptions. Counties and cities add their own layers on top of state rates. The result: over 12,000 distinct sales tax jurisdictions across the country.
For a restaurant owner, this complexity shows up in practical ways. In Texas, food sold for immediate consumption (restaurant meals) is taxable at the full rate. In California, food sold at a restaurant is taxable, but certain "to-go" orders may be partially exempt depending on the nature of the item. In Colorado, the state rate is 2.9% but Denver adds 4.81% and RTD transit district adds another 1% — meaning a Denver restaurant collects 8.81% combined.
States with No Sales Tax
Five states have no state sales tax: Alaska, Delaware, Montana, New Hampshire, and Oregon. Restaurant owners in these states have no state-level collection obligation, though Alaska allows local governments to levy their own sales taxes.
What Counts as Taxable Food
Most states tax "prepared food" — anything sold ready to eat. The distinction between taxable prepared food and exempt groceries is a frequent source of confusion and audit exposure. General rules:
- Dine-in restaurant meals: taxable in virtually all states that have sales tax
- Takeout meals (hot): generally taxable as prepared food
- Catering services: generally taxable, often at a higher combined rate
- Alcohol: taxable (often at a higher rate than food)
- Non-alcoholic beverages: varies significantly by state
Configuring Your POS for US Sales Tax
A restaurant POS operating in the US must:
- Know the combined sales tax rate for its exact location (state + county + city + special district)
- Apply different tax rates to different item categories if the state distinguishes between food types, alcohol, and non-food items
- Track taxable vs. exempt sales separately for monthly remittance calculations
- Generate reports that show gross sales, taxable sales, exempt sales, and tax collected — by period
OneScale allows tax rates to be configured per location and per item category. A Texas restaurant can configure 8.25% on all food and beverage, while separately configuring higher rates for alcohol if required by local ordinance. Reports break out taxable and exempt sales automatically.
When to Remit: Filing Frequencies
Most states require monthly sales tax remittance for businesses above a revenue threshold, with quarterly filing for smaller businesses. Some states require prepayments. Missing a remittance deadline triggers penalty interest — typically 1–2% per month on unpaid tax. Most states also have a "look-back" period of 3–5 years during which they can audit past filings.
Nexus and Multi-State Operations
A restaurant with locations in multiple states has "nexus" in each state and must register and collect sales tax in each. Since the 2018 South Dakota v. Wayfair Supreme Court decision, economic nexus rules also apply to online sales — relevant for restaurants selling packaged goods or gift cards online.
Tip Handling and Sales Tax
Mandatory gratuities (auto-gratuities above a certain party size, mandatory service charges) are generally treated as part of the taxable sale in most states. Voluntary tips left by customers are not. Your POS must distinguish between mandatory service charges and voluntary tips, applying tax correctly to each.
Conclusion
US sales tax compliance for restaurants requires a POS configured for your specific jurisdiction, with the ability to distinguish between item types, generate clean remittance reports, and maintain the audit trail that state authorities require. Getting this right from the start is far less expensive than a state audit that uncovers years of under-collection.
