The Rule: Both Periods Must Be Under AED 3M
Small Business Relief requires revenue to be at or below AED 3 million in both the current tax period AND the prior tax period. If either period exceeds the threshold, SBR is not available.
Most businesses only check the current year. They see revenue under AED 3 million and assume SBR applies. But the FTA also looks backwards — and if last year was over AED 3 million, the election is blocked.
SBR is available only if revenue does not exceed AED 3 million in the current tax period AND the preceding tax period. Breaching the threshold in either period disqualifies you. This is not a soft guideline — it's a hard rule in the legislation.
Worked Example: Mr. Y — SBR Blocked
Mr. Y's Situation
Mr. Y operates a business in Sharjah. He is a UAE resident person for corporate tax purposes. His tax period ends on 31 December each year.
Current period (ending 31 December 2026): Revenue = AED 1.9 million
Prior period (ending 31 December 2025): Revenue = AED 4.3 million
Question: Is Mr. Y eligible for SBR for the tax period ending 31 December 2026?
The answer: Mr. Y is not eligible for Small Business Relief for the tax period ending 31 December 2026. Although his current revenue (AED 1.9 million) is well below the AED 3 million threshold, his prior period revenue was AED 4.3 million — which exceeded the threshold. The prior period breach blocks SBR in the current period.
Mr. Y must file a full corporate tax return for FY2026 — calculating taxable income, applying the 9% rate on income exceeding AED 375,000, and paying any tax due.
More Examples — Testing the Rule
| Scenario | Current Period Revenue | Prior Period Revenue | SBR Available? |
|---|---|---|---|
| Company A | AED 2.5M | AED 2.8M | ✅ Yes — both under AED 3M |
| Company B | AED 1.0M | AED 3.5M | ❌ No — prior period over AED 3M |
| Company C | AED 3.2M | AED 2.0M | ❌ No — current period over AED 3M |
| Company D | AED 0 (dormant) | AED 4.0M | ❌ No — prior period over AED 3M |
| Company E | AED 2.9M | AED 2.9M | ✅ Yes — both at/under AED 3M |
| Mr. Y | AED 1.9M | AED 4.3M | ❌ No — prior period over AED 3M |
Company D is the most surprising case: the company had zero revenue this year but still can't elect SBR because last year's revenue was AED 4 million. Even a fully dormant current year doesn't override the prior period breach.
Why This Rule Exists
The prior period rule prevents businesses from "yo-yo-ing" between SBR and full CT filing by manipulating the timing of revenue recognition. Without it, a company could earn AED 5 million in Year 1, defer income to bring Year 2 under AED 3 million, elect SBR in Year 2 to avoid tax, then earn again in Year 3.
The prior period check ensures that SBR is truly for consistently small businesses — not for companies that had a quiet year between active ones.
What to Do If SBR Is Not Available
If the prior period rule blocks SBR, you must file a full corporate tax return:
Calculate taxable income. Revenue minus allowable deductions minus exempt income = taxable income.
Apply the tax rate. 0% on the first AED 375,000 of taxable income. 9% on everything above.
Prepare financial statements. Full IFRS or IFRS for SMEs financials are needed to support the return — unlike SBR where financials aren't required.
File by the deadline. 9 months after the financial year end. Late filing = AED 500/month.

Plan Ahead: The AED 3M Danger Zone
If your revenue is approaching AED 3 million in the current year, think about next year too. Crossing AED 3 million this year doesn't just affect this year's return — it blocks SBR next year as well, even if next year's revenue drops.
This has planning implications: if you're at AED 2.8 million and considering a large contract that would push you to AED 3.2 million, the additional AED 400,000 in revenue could cost you SBR eligibility for two consecutive years — the current year (over AED 3M) and the following year (prior period rule).

Remember: Losses Under SBR Are Wasted
One silver lining of losing SBR eligibility: if your company has genuine losses, you can now carry them forward to offset future taxable income. Under SBR, losses are deemed zero and can't be carried forward. Under full CT filing, losses are real and can reduce future tax bills. If your business is in a loss-making period, losing SBR might actually work in your favour.
