Sales Tax Refunds
Supporting Documentation


The Comptroller uses supporting documentation, such as copies of invoices, cancelled checks, and executed contracts, to verify refund claims. If supporting documentation is voluminous, the refund claim must instead include a statement that all supporting documentation necessary to verify the claim will be made available to the Comptroller upon request. Alternatively, if you have more than ten invoices, provide a schedule of the required invoice information. You can use the sample schedule (PDF, 25KB) as a guide.
