UAE Corporate Tax Transitional Rules for SMEs: What You Need to Know

The introduction of UAE Corporate Tax (CT) from June 2023 brought with it a set of transitional rules designed to ease the move from a zero-tax to a 9% corporate tax environment. These transitional provisions affect how UAE businesses treat assets and liabilities held before the CT regime began, how losses accrued pre-CT are treated, and certain elections and applications that must be made in the first CT period. For UAE SMEs now in their second or third CT filing period, understanding these transitional rules — and whether any elections or adjustments are still available — is an important compliance and planning consideration.

Small Business Relief — The Most Important Transitional Provision for UAE SMEs

The UAE Corporate Tax Law provides a Small Business Relief (SBR) election for UAE businesses with revenue of AED 3 million or less in a given tax period. A business that elects SBR is treated as having zero taxable income for that period — effectively paying no Corporate Tax, regardless of its actual profitability. SBR is available for tax periods ending on or before December 31, 2026 (with potential extension). It must be elected annually in the tax return — it is not automatic.

SBR is available to all UAE tax residents with revenue at or below the AED 3 million threshold, except for businesses that are part of a Multinational Enterprise (MNE) group subject to Pillar Two global minimum tax. For eligible UAE SMEs with revenues below AED 3 million, electing SBR in each eligible period eliminates CT liability entirely for those years. Businesses should confirm their eligibility with their UAE tax advisor each year, as the revenue threshold is measured on the total revenue of the taxable person (not just profit).

Opening Balance Sheet Adjustments Under UAE CT

The UAE CT Law allows businesses to make certain elections regarding the opening balance sheet values for CT purposes. Businesses may elect to use the net book value of assets as at the start of the first CT period (i.e., the carrying value in the accounts) rather than the original cost — which means accumulated depreciation on older assets effectively carries forward at the lower book value, providing lower future depreciation deductions but avoiding complex historical cost tracking.

For UAE real estate holding businesses, there is an important election regarding whether to use the historical cost or market value as the opening CT basis of real property assets. This election has significant implications for the gain that would be recognised on a future disposal of the property — businesses holding significantly appreciated real estate should review this election with a UAE tax advisor before the deadline in their first CT filing.

Interest Limitation Rules and Transitional Considerations

UAE CT introduces an interest limitation rule restricting the deductibility of net interest expense to 30% of adjusted EBITDA. Excess interest (interest above the 30% cap) can be carried forward to future periods. For UAE SMEs with significant loan financing — property mortgages, working capital facilities — the interest limitation rule may reduce the tax deductibility of their borrowing costs.

The transitional aspect here is that existing loan arrangements entered before the CT regime began are subject to the same limitation as new loans — there is no grandfathering for pre-existing debt. UAE SMEs with high levels of related-party or third-party debt should model the interest limitation impact in their CT planning, and consider whether refinancing on different terms could improve the position.

CT Registration, Filing Deadlines, and Penalties

All UAE businesses (with very limited exceptions) are required to register for Corporate Tax with the Federal Tax Authority, regardless of whether they have taxable income. Registration was required within specific deadlines from the first CT period — late registrations are subject to penalties of AED 10,000 for the first instance. CT returns must be filed within nine months of the end of the relevant tax period; failure to file on time attracts penalties of AED 500 per month for the first twelve months.
