Can I make quickbooks online recognize our specific tax structure its 7% and capped at $500.00 so $35.00 maximum sales tax ?
No, QB can not do a tax set up like that. QB is just a straight percentage of the sale as sales tax. There is no special handling for caps like you see in luxury purchases in some states. Or a split sales tax, where there is one percentage on the first x-amount, and a different percentage on the rest
