Food, except preapred foods like rotisserie chicken or deli sandwiches, is not taxable. OTC medications are also not taxed (like Advil, Zantac, etc.)The tax rate varies by county. In lake County where I live it's 7%. Where is your vacation rental?
Hope this helps. If you need more I can probably dig out more receipts.
