Most UAE companies cannot avoid corporate tax, but most are paying more than they legally need to. Since 2023 the UAE has charged 9% corporate tax on taxable income above AED 375,000, and the Federal Tax Authority (FTA) has shown it will penalise late registration (AED 10,000), late returns and incorrect filings. The good news: the law itself gives businesses several legitimate levers — reliefs, deductions, free zone treatment and credits — that reduce what you actually pay. This guide explains each lever, who qualifies, and what to do before the 30 September 2026 filing deadline for calendar-year 2025 accounts.
What corporate tax do UAE businesses pay in 2026?
The UAE applies a 9% corporate tax rate on taxable income exceeding AED 375,000, with 0% below that threshold, under Federal Decree-Law No. 47 of 2022 as published by the Ministry of Finance. Qualifying Free Zone Persons pay 0% on qualifying income. Your liability is not the rate alone — it is taxable income after every deduction, relief and credit you are entitled to claim. Reducing liability legally means making sure each layer is applied correctly.
Lever 1: Small Business Relief (extended to 31 December 2029)
If your revenue does not exceed AED 3 million for the relevant tax period and all previous periods, you can elect Small Business Relief and be treated as having no taxable income for that period — you still file a simplified return, but pay no corporate tax. The Ministry of Finance has extended Small Business Relief until 31 December 2029, so calendar-year businesses with revenue at or below AED 3 million remain covered for tax periods ending on or before that date.
Key conditions from the FTA's Small Business Relief guidance:
- Revenue is measured for the relevant tax period and all previous tax periods — one strong year disqualifies you from that point onward.
- The election is made through your corporate tax return, not a separate application.
- Banks and large multinational groups are excluded.
You must still register, file on time and keep records. The FTA confirmed in August 2026 that Small Business Relief does not remove the obligation to file — companies with a 31 December 2025 year end had to file by 30 September 2026.
Lever 2: Free zone 0% rate — and keeping it
If you operate in a free zone, a 0% rate on qualifying income can eliminate corporate tax on most of your profit. Qualifying activities are listed in Ministerial Decision No. 229 of 2025, which replaced the earlier MD 265 of 2023.
The 0% rate is not automatic. To remain a Qualifying Free Zone Person you must:
- Hold a free zone licence and maintain adequate substance in the zone.
- Earn qualifying income only — non-qualifying revenue must stay within the de minimis threshold of the lower of 5% of total revenue or AED 5 million (per Ministerial Decision No. 229 of 2025).
- Keep audited financial statements.
- Follow the transfer pricing rules for transactions with related parties.
Losing any condition costs more than the tax saved: the business ceases to be a Qualifying Free Zone Person for the current and the following four tax periods. Many owners reduce liability here simply by tightening how they document substance and revenue splits — before an audit, not after.
Lever 3: Claim every allowable deduction
Taxable income is accounting income after deductions the law allows. Businesses routinely overpay because of unclaimed or misclassified expenses:
- Fully deductible costs incurred wholly for the business — salaries, rent, licence fees, professional services, marketing.
- Depreciation on assets using the tax amortisation rules instead of a book rate that understates deductions.
- Tax losses carried forward for up to 10 years against future profits, where ownership continuity conditions are met.
- Interest limitations — net interest expense is deductible up to 30% of EBITDA; structuring financing deliberately keeps more of it deductible.
- Transfer pricing — related-party transactions must be priced at arm's length and documented; poor documentation often means missed deductions or exposed adjustments.
Lever 4: The R&D Tax Credit (from 1 January 2026)
Technology, manufacturing and product businesses can now claim a research and development credit. Under Cabinet Decision No. 215 of 2025, implemented by Ministerial Decision No. 24 of 2026 and launched as Phase 1 of the UAE's R&D Tax Incentives Programme in March 2026:
- The credit applies to qualifying R&D expenditure conducted in the UAE, aligned to OECD Frascati Manual definitions.
- Credit rates are tiered: 15% on the first AED 1 million of qualifying expenditure, 35% on the portion up to AED 2 million, and 50% on the portion up to AED 5 million — subject to minimum UAE employee thresholds (2, 6 and 14 employees respectively).
- Qualifying expenditure is uplifted by 30% for attributable overheads.
- Unutilised credit carries forward against future corporate tax.
Lever 5: Structure, timing and grouping
- Group relief: losses can be transferred between UAE group members where the 75% ownership and other conditions are met.
- Business restructuring relief can make intra-group transfers tax-neutral where conditions are met.
- Tax period choice for new businesses can align the first filing with a quieter trading period.
- Timing of capital expenditure — assets bought before year end start generating depreciation deductions sooner.
What reduces your tax bill legally vs. what exposes you to penalties
The FTA distinguishes clearly between lawful relief and evasion. Late or incorrect filings carry escalating penalties: AED 500 per month (or part thereof) for the first 12 months of a late return, rising to AED 1,000 per month from the thirteenth month, per the FTA's penalty guidance. Late registration itself carries a AED 10,000 penalty, though the FTA's late registration waiver initiative has forgiven many first-time cases since April 2025.

Frequently asked questions
Is tax planning legal in the UAE?
Yes — choosing the right corporate structure, claiming legitimate deductions and electing reliefs the law provides is lawful. What is not lawful is hiding income, inventing expenses, or splitting one business artificially to fit a relief threshold; those attract reassessment and penalties under the corporate tax law.
Can I get both Small Business Relief and the free zone 0% rate?
They answer different questions. Small Business Relief treats eligible revenue ≤ AED 3m businesses as having no taxable income; the free zone 0% applies to qualifying income of a Qualifying Free Zone Person. Assess both against your actual structure — the right one depends on your licence, revenue history and income type.
What is the first step to lower my corporate tax bill?
Reconcile last year's return against the full list of allowable deductions, reliefs and credits you never claimed — most businesses find the largest immediate saving there. Our corporate tax filing service reviews this before every deadline.
