- Starting April 1, 2025, all businesses, including new ones with a simplified accounting system, will be required to submit monthly VAT declarations, as decided by the Independent Public Revenue Authority. From January 1, 2024, to March 31, 2025, monthly VAT submissions will begin on July 1, 2025, while prior to December 31, 2023, monthly submissions remain optional starting October 1, 2025; after 24 months of operation or 12 months of monthly submissions, businesses can opt for quarterly filings, though switching between monthly and quarterly requires a 12-month commitment. Monthly submissions aim to combat tax evasion, while optional monthly filings assist with cash flow management and reduce the risk of VAT non-payment.
