California Sales Tax for Interior Designers - Records
You are required to keep complete records documenting your sales and purchases. For nontaxable transactions, those records should clearly indicate the reason the transaction was not subject to tax. You should maintain resale and exemption certificates and other information necessary to back up each exemption or deduction. You should keep required records for at least four years unless CDTFA gives you specific, written authorization to destroy them sooner. If you are being audited, you should retain all records that cover the audit period until the audit is complete, even if that means you keep them longer than four years. In addition, if you have a dispute with CDTFA about how much tax you owe, you should retain the related records until that dispute is resolved. For instance, if you appeal the results of an audit or another determination (billing), or you file a claim for refund, you should keep your records while that matter is pending.
