Compile all necessary documents, including financial statements, invoices, receipts, and previous tax returns. Organize these documents in a logical order to make them easily accessible during the audit. Ensure that all records are complete and accurate, as discrepancies can lead to further scrutiny. It is advisable to cross-check your documents against the FTA requirements to ensure nothing is overlooked. Maintaining a comprehensive record-keeping system not only aids in audits but also supports ongoing business operations.
