National Auditing Services, LLC operates in the accounting sector as a nationwide consulting and auditing firm based in Los Angeles, California. Founded in 1995, it has helped hundreds of clients recover tens of millions of dollars in overpaid sales tax. The company specializes in reverse sales and use tax recovery, focusing on refunds in areas the state typically overlooks in standard compliance work.

Its services target manufacturers and other businesses navigating increasingly complex state and local tax rules. The firm follows a multi-step process—from on-site invoice reviews to legal verification and refund claim submission—then takes responsibility for follow-up, with all audit expenses covered and fees payable only if savings are recovered.
