VAT and accounting form the operational backbone for UAE businesses, requiring disciplined systems from incorporation to avoid penalties, cash flow disruptions, or banking complications. VAT operates as a 5 percent consumption tax on most goods and services supplied in the UAE, while accounting ensures accurate records that support tax filings, audits, and compliance with corporate tax obligations. As of February 2026, founders must treat these as integrated processes rather than annual exercises, particularly with small business relief for corporate tax available only through tax periods ending December 31, 2026. The fundamentals depend on revenue thresholds, activity type, jurisdiction, and whether supplies qualify as taxable, zero-rated, exempt, or subject to reverse charge.
