Do Small Businesses Need to Register for Corporate Tax in 2026?

Corporate Tax Rate for Small Businesses in 2026

• 0% tax on taxable income up to AED 375,000

Small Business Relief (SBR) – Key for SMEs

If your annual revenue is below AED 3,000,000, you can elect for Small Business Relief. This means you are treated as having no taxable income – so you pay 0% corporate tax even if your profit exceeds AED 375,000. However, you must still register and file tax returns. This relief is available until December 31, 2026.
