UAE R&D Tax Credit 2026: How to Calculate Your 15%, 35% or 50% Credit

The UAE R&D tax credit introduced by Ministerial Decision No. 24 of 2026 is the most valuable incentive in the corporate tax framework so far, and the one most likely to be miscalculated. It applies to tax periods commencing on or after 1 January 2026 and works as a direct offset against corporate tax payable rather than a deduction from taxable income — which is why a credit dirham is worth about eleven times a deduction dirham at the 9% rate. The mechanics are not complicated, but they are unforgiving: two thresholds apply at the same time, the bands are cumulative rather than cliff-edge, and the headline "up to 50%" is capped in a way that is easy to over-read. This guide sets out the calculation band by band. Before running the numbers, check the work itself passes the five eligibility tests — our guide to qualifying R&D activities covers those. If you want the numbers run on your own figures, our corporate tax advisory team models the credit and handles the pre-approval.

What is the UAE R&D tax credit and how does it work?

The R&D tax credit is a reduction against your corporate tax liability, awarded on qualifying research and development expenditure incurred in the UAE. It was introduced under Ministerial Decision No. 24 of 2026, implementing Cabinet Decision No. 215 of 2025, and applies to tax periods commencing on or after 1 January 2026.

The distinction between a credit and a deduction is worth spelling out, because it drives the entire economics. A deduction of AED 1,000,000 reduces taxable income, saving AED 90,000 of tax at 9%. A credit of AED 1,000,000 reduces the tax bill itself by AED 1,000,000. The same headline number is worth roughly eleven times more as a credit. That is why the compliance burden attached to it — pre-approval, documentation, a seven-year retention requirement — is proportionate rather than excessive.

Two structural points before the arithmetic. The credit requires pre-approval from the competent authority before it can be claimed on a return, so it cannot be picked up retrospectively at filing time. And research in the social sciences and arts is outside the scope — this is an incentive for scientific and technological advance, not for research generally.

What are the 15%, 35% and 50% R&D tax credit tiers?

The credit runs on two simultaneous conditions: a qualifying expenditure band and a minimum average R&D staff count. Both must be satisfied for a given band to be credited at that band’s rate.

The bands are cumulative, not cliff-edge. Spending AED 3,500,000 does not credit the whole amount at 50%; it credits the first AED 1,000,000 at 15%, the second AED 1,000,000 at 35%, and the remaining AED 1,500,000 at 50%. This works the same way as a progressive rate table, and it is the single most common source of over-estimated credits.

Worked example: TechBuild FZ LLC, tax period 1 Jan – 31 Dec 2026

TechBuild has taxable income of AED 20,000,000. Its corporate tax before the credit is (20,000,000 − 375,000) × 9% = AED 1,766,250 — remember the first AED 375,000 of taxable income is taxed at 0%. Applying the credit leaves AED 516,250 payable, a reduction of 70.8%. You can sense-check the pre-credit figure with the UAE corporate tax calculator.

How much R&D tax credit can you actually claim?

Qualifying expenditure is capped at AED 5,000,000 per tax period. Run the bands to that ceiling and the maximum credit any entity can earn is AED 2,000,000: AED 150,000 + AED 350,000 + AED 1,500,000.

Expenditure above AED 5,000,000 earns nothing further, which has a planning consequence worth noting: for a group running a large R&D programme, the marginal value of spend inside a single entity falls to zero once the cap is hit. Where the group has more than one qualifying entity, how the programme is allocated between them matters — see the Tax Group section below, which cuts the other way.

How is average R&D staff calculated?

The staff figure is an average across the months in which qualifying R&D activity was actually undertaken — not a year-end snapshot, and not necessarily an average over twelve months.

1. Count R&D staff for each month — record the number of qualifying R&D staff for each calendar month in the tax period. Someone joining mid-month counts for that month.
2. Sum the monthly counts — add the figures for every month in which R&D activity was actively undertaken.
3. Divide by active R&D months — use the number of months in which qualifying activity took place, not the full twelve.

That third step is more generous than it first appears. A company that ran a concentrated three-month development programme from January to March with 12 R&D staff has an average of 12, not 3. The denominator is the three active months, not the calendar year. Conversely, a company that keeps a thin R&D function ticking over all twelve months gets no such lift. Where a programme is genuinely seasonal or project-based, this rule can be the difference between clearing a band threshold and missing it.

Externally provided workers count. R&D staff is not limited to people on your own payroll: full-time-equivalent contractors and secondees directly and actively engaged in qualifying R&D are included where they meet the conditions in the Decision. Keep timesheets and contracts that evidence the engagement — our payroll team maintains the records that support the count.

What happens if your staff count falls below the next threshold?

You do not lose the credit — the band steps down. Where the staff threshold for a band is not met, that band is credited at the highest rate for which both conditions are satisfied. Lower bands you did clear keep their own rates.

The planning point is immediate. Lifting the average from 10 to 14 would credit that final AED 500,000 at 50% instead of 35% — AED 75,000 more, taking the total to AED 750,000. Four qualifying R&D heads, averaged over the active months, for AED 75,000 of additional credit in that year alone.

The step-down works the same way further down the table. A company spending AED 3,000,000 with an average of only 5 R&D staff clears the 2-staff test but not the 6-staff test, so every band is credited at 15%: AED 3,000,000 × 15% = AED 450,000. And headcount without spend is equally constrained — 20 R&D staff supporting only AED 800,000 of qualifying expenditure earns AED 800,000 × 15% = AED 120,000, because there is no expenditure in the higher bands to credit.

Can a Tax Group pool R&D expenditure and staff?

Yes. Where entities form a Tax Group under the Corporate Tax Law, the qualifying R&D expenditure and R&D staff of the qualifying entities are aggregated when applying the band thresholds. For groups running R&D across several subsidiaries this is often the single largest lever available.

Same spend, same people, AED 235,000 more credit — entirely from how the entities are grouped for tax purposes. Tax Group formation carries its own consequences well beyond the R&D credit, so it is not a decision to take on this basis alone, but it belongs in the analysis. Note the cap presumably applies to the pooled figure rather than per member, which is the point at which grouping stops helping a very large programme.

What is the 30% staff cost uplift?

When computing qualifying R&D expenditure, staff costs are uplifted by 30% to reflect overheads reasonably attributable to R&D activity. The credit is then calculated on the uplifted figure, so your qualifying base is larger than your cash outlay.

If R&D staff costs — salaries, allowances, medical insurance, pension, end-of-service gratuity, bonuses and training — total AED 2,000,000, the qualifying expenditure recognised from staff costs alone is AED 2,600,000. On its own, with 14+ average R&D staff, that produces AED 150,000 + AED 350,000 + (AED 600,000 × 50%) = AED 800,000 of credit against a AED 2,000,000 cash spend.

Two practical consequences. First, accurate payroll allocation between R&D and non-R&D roles is worth real money — every AED 100,000 correctly attributed to R&D becomes AED 130,000 of qualifying base. Second, the uplift can carry a mid-sized programme over a band threshold on its own, so compute it before concluding which tier you reach. Our accounting team handles the cost identification, the split and the uplift computation.

Is the R&D tax credit refundable, and can it be carried forward?

The credit is non-refundable. If it exceeds your corporate tax liability for the period, the surplus is not paid out in cash. Unutilised credit may instead be carried forward to offset corporate tax and top-up tax in later periods, subject to ownership continuity.

• The same person or persons must have continuously owned at least 50% of the qualifying entity from the period in which the credit arose to the period in which it is used; or
• Where ownership changes by more than 50%, the entity must continue to carry on the same or a similar business activity.
• Entities listed on a Recognised Stock Exchange are outside the ownership continuity requirement.

The practical implication is for early-stage and venture-backed companies, which are precisely the businesses most likely to generate credits before they generate taxable profits. A pre-revenue technology company banking credits through successive funding rounds needs to watch cumulative dilution against the 50% continuity test — a Series B that takes founders below 50% collectively can put previously banked credits at risk unless the same-or-similar business limb is satisfied. Track the carried-forward balance and the ownership position together, period by period, rather than discovering the interaction at exit.

When can the R&D tax credit be clawed back?

Credits are subject to claw-back within five years where the entity ceases to be a Taxable Person, becomes a Qualifying Free Zone Person, applies Small Business Relief, enters liquidation, or redomiciles outside the UAE. The five-year window means the claim is a five-year commitment, not a one-year decision.

For an R&D-intensive free zone business the comparison is genuinely close and worth running with numbers. QFZP status delivers 0% on qualifying income indefinitely, provided the conditions hold every year. The R&D credit delivers up to AED 2,000,000 a period against a 9% liability, with no substance conditions beyond the R&D itself — but it is capped, it is non-refundable, and claiming it locks you out of QFZP for five years. Which wins depends on the size of the qualifying income and the durability of the QFZP conditions, and the answer is rarely obvious from the headline rates.

How do you claim the credit — pre-approval and filing?

Pre-approval from the competent authority is mandatory before the credit can be claimed, so the sequence matters. A claim assembled at filing time, after the tax period has closed and without approval in hand, is not a claim.

1. Test the activity — confirm the work is scientific or technological R&D and passes all five qualifying tests. Social sciences, humanities and the arts are excluded.
2. Identify the costs — staff costs, consumables and subcontracting, classified correctly and separated from general operating expenditure.
3. Compute the staff average — month by month across active R&D months, including full-time-equivalent external workers.
4. Apply the uplift and the bands — uplift staff costs by 30%, then run the expenditure through the three bands with the staff test at each.
5. Obtain pre-approval — submit the application to the competent authority ahead of the return.
6. Claim in the CT return and retain records — file the credit with the return and keep the supporting documentation for seven years.

Documentation is where claims are won or lost. Contemporaneous project records, technical narratives explaining the uncertainty being resolved, timesheets tying people to projects, and a clean audit trail from the ledger to the claim schedule — assembled during the year, not reconstructed afterwards.

Key terms used in this guide

The R&D credit rewards businesses that were going to do the research anyway and can evidence it properly. The two things that most often cost money are both avoidable: over-estimating the entitlement by applying 50% to the whole spend, and missing a band threshold by a headcount that could have been reached. Model it early in the year, not at filing. Our corporate tax team assesses eligibility, computes the tiered credit, handles pre-approval and files it with the return.
