Home consumption to me means take out too.
I know for sure in CA if it's to go, there's no tax. The people at Coffee Bean always remind their customers to say the food/drinks are to go.
Groceries in that table generally means unprepared food. It's a general summary, so obviously you have to look at specific states for details, but for Ohio, they only charge tax on prepared food for dine-in. All other food (unprepared, or prepared take-out) is tax exempt.
Really? Maybe it's just CB. I'll pay attention the next few times.
WikipediaIn grocery stores, unprepared food items are not taxed but vitamins and all other items are. Ready-to-eat hot foods, whether sold by supermarkets or other vendors, are taxed. Restaurant bills are taxed. As an exception, hot beverages and bakery items are tax-exempt if and only if they are for take-out and are not sold with any other hot food. If consumed on the seller's premises, such items are taxed like restaurant meals. All other food is exempt from sales tax.
