Read the tax column correctly
Tax is the sales tax, VAT, MwSt, TVA, IVA, or BTW printed on the receipt, with multiple rates added into one number. It is not the tax you owe and not a deduction amount. Subtotal is the pre-tax figure when the receipt prints one. Total is the grand total, tip included when you added a tip. Don’t add the tax column on top of the total.
