Hi @Hottamale182.
As long as you have set up your sales taxes in Accounts & Settings, and indicated in your item library which items and services are taxable and which are not, then the standard Reports -> Taxes report will tell you the exact amount that was taxable for the period, as well as the total tax due to each of your taxing authorities.
There is no customer by customer report showing such an audit. I’ve never heard of needing one. I’m assuming that you are letting Square determine the proper sales taxes — or if you are selling to lots of states that you have an app like TaxJar that collects and remits sales taxes. The only “audit” that I know of would exist by downloading the Transactions Detail CSV file which lists taxes collected for each item/service in a transaction. But that would require you to do those calculations/audits in a spreadsheet.
What kind of business is yours that you feel you would need such a detailed audit, if I may ask?
