Idaho charges 6% sales tax on prepared food and beverages sold at restaurants. Unlike some states that exempt groceries, Idaho taxes food across the board. For restaurants, nearly everything you sell is taxable. The food, the drinks, the desserts, the to-go orders. All of it.

Tips are not subject to sales tax. The tax applies to the menu price of what the customer orders, not to gratuities they add on top. Your POS system should be configured to calculate tax before tips are applied. If it’s calculating tax on the total including tip, that’s a problem you need to fix.

Alcohol follows the same 6% rate as food in Idaho. Some states layer additional taxes on liquor sales, but Idaho keeps it straightforward. Collect the same rate on beer, wine, and cocktails as you do on burgers and fries.

The operational side comes down to your point of sale system and your record keeping. Your POS needs to track taxable sales separately from the tax collected. At month end, you should be able to pull a report showing exactly how much sales tax you owe. If you’re manually calculating this from total revenue, you’re creating work and inviting errors.

Filing frequency depends on how much tax you collect. Restaurants with higher volume file monthly. Smaller operations might file quarterly or annually. The Idaho State Tax Commission assigns your filing frequency based on your tax liability. Most established restaurants in the Treasure Valley end up on monthly filing because the numbers add up quickly.

The money you collect isn’t your money. It belongs to the state from the moment a customer pays it. Treat sales tax as a liability in your books, not as revenue. Mixing it into your operating cash and spending it before the filing deadline is one of the fastest ways to get into trouble with the state. Sales tax compliance might seem simple, but the consequences of getting behind add up fast.

Keep records of your daily sales totals, the tax collected, and any adjustments like refunds or voids. If you’re audited, the state wants to see that your reported numbers match what actually happened. Good documentation from your POS and your Nampa accounting team makes audits go smoothly. Sloppy records make them expensive.

Some restaurants run into issues when they sell items that might seem like grocery products. A coffee shop selling bags of whole beans, a bakery selling uncut cakes for pickup. These could potentially be treated differently depending on how they’re sold and packaged. When you’re unsure whether something qualifies as prepared food or a grocery item, get clarification before you start selling it. The distinction matters for compliance.

The biggest mistake restaurants make is treating sales tax as an afterthought. They collect it, spend it, then scramble to come up with the money when the filing deadline arrives. Build the discipline of setting aside sales tax immediately. Transfer it to a separate account if that helps you not touch it. The state expects their money on time, and the penalties for being late are not worth the short-term cash flow benefit.
