Most states have a sales tax on products and it’s typically collected by the state’s Department of Revenue. Usually, this type of tax debt is triggered by a sales tax audit. The state will often request accounting statements, state and federal returns, invoices, purchase orders, and any other financial statements from the business. Because sales tax is typically collected at the point of sale, the state is very unlikely to work with you, so representation is key. Having an expert on your side during a sales tax audit will help build your best case, and likely minimize your liability and chance of aggressive actions.
