UAE R&D Staff Thresholds Explained: The 2, 6, 14 Rule

The Numbers That Decide Your Credit Rate

The UAE R&D tax credit has three rate tiers: 15% on the first AED 1 million of qualifying spend, 35% on the next AED 1 million, and 50% on the final AED 3 million. To actually get each rate, your entity must meet a minimum R&D staff count.

The thresholds are set in Ministerial Decision No. 24 of 2026 and are:

• Tier 1 (15%): At least 2 R&D staff
• Tier 2 (35%): At least 6 R&D staff
• Tier 3 (50%): At least 14 R&D staff

These thresholds are not optional guidelines. They are hard gates. If you have an average of 5 R&D staff across the year and claim AED 2 million of qualifying expenditure, your credit is capped at the 15% rate on the full amount because you did not reach the 6-staff threshold for the second tier. The math matters, which is why the exact method for calculating "R&D staff" matters.

This post walks through how the counts are actually done.

What Counts as "R&D Staff"

Before you can count heads, you need to know who counts. Ministerial Decision No. 24 Article 2.4, in combination with Article 8, defines R&D staff as employees:

• Under the entity's supervision, direction, and direct control
• Physically based in the UAE
• Actively engaged in qualifying R&D activities

Each of these three elements matters.

Supervision and control. Independent contractors, freelancers, and outsourced resources do not count as R&D staff. They may count as subcontracting expenditure under Article 5.1.c, but they do not contribute to your staff threshold.

UAE-based. Employees working remotely from outside the UAE do not count, even if they are on your payroll. The substance test is physical presence in the UAE during R&D work.

Actively R&D. An employee does not become R&D staff just because they work at an R&D company. They must be engaged in the qualifying R&D activities themselves, or in direct supervision of those activities. Sales, marketing, HR, finance, and executives who are not working on R&D do not count, even if their salaries are higher.

Staff who fail any of the three conditions are out of the count. No exceptions.

A Practical Headcount Calculation

Ministerial Decision No. 24 Article 2.4 sets the measurement method explicitly: the R&D staff count is the average of the monthly R&D full-time equivalent (FTE) count across the Tax Period or Fiscal Year. This is the method the law prescribes, and it is the method our platform uses by default.

For each month in the tax period, you compute the R&D FTE count using this formula:

> Monthly FTE = sum of (rd_time_percentage × fte_equivalent) for all R&D-active employees that month

Where:

• rd_time_percentage is the portion of that employee's working hours spent on R&D in that month (0-100%)
• fte_equivalent is the employee's full-time equivalent weight (1.0 for full-time, 0.5 for half-time, etc.)

For example, if an employee works full-time (fte_equivalent = 1.0) but spends only 60% of their time on R&D (rd_time_percentage = 60), their contribution to the monthly FTE count that month is 0.6.

Once you have a monthly FTE number for each of the twelve months, the annual threshold test is the simple average across the months:

> Average monthly FTE = sum of monthly FTEs / number of months with any R&D activity

If your average monthly FTE is at least 2, you unlock Tier 1. At least 6, Tier 2. At least 14, Tier 3. Anything less than 2 and the entity cannot claim the credit at all.

A Worked Example

Imagine a mid-sized UAE company with 18 employees on payroll. The breakdown:

• 10 full-time R&D engineers (fte=1.0, rd_time=100%), contributing 10.0 FTE per month
• 2 part-time R&D engineers (fte=0.5, rd_time=100%), contributing 1.0 FTE per month
• 3 product managers who split 50/50 between R&D and commercial work (fte=1.0, rd_time=50%), contributing 1.5 FTE per month
• 2 executives who are not R&D-active, contributing 0 FTE
• 1 finance controller who is not R&D-active, contributing 0 FTE

Total R&D FTE per month = 10 + 1 + 1.5 = 12.5

This company has 18 employees on payroll but only 12.5 average monthly R&D FTE. They qualify for Tier 2 (35% rate) because they exceed 6. They do not qualify for Tier 3 (50%) because they do not reach 14.

If the company added 2 more full-time R&D engineers in July, their monthly FTE for the second half of the year would be 14.5. Their annual average would be:

> (12.5 × 6 months) + (14.5 × 6 months) / 12 = 13.5

Still not enough for Tier 3. They would need to add 2 full-time R&D engineers by January, not July, to meet the Tier 3 threshold for that tax year.

Part-Time Staff and the R&D Time Apportionment

The two variables that trip companies up most often are part-time FTE and R&D time apportionment.

Part-time FTE reflects how many hours the employee works relative to a full-time employee. A person contracted at 20 hours per week in a company where full-time is 40 hours per week has an fte_equivalent of 0.5. This is a contractual definition.

R&D time apportionment reflects how much of the employee's working time is actually spent on qualifying R&D. A full-time employee who spends 60% of their time on R&D and 40% on customer support has an rd_time_percentage of 60. This is a time-tracking definition.

The two multiply. The part-time employee who works 20 hours a week and spends all of those hours on R&D contributes 0.5 × 100% = 0.5 FTE. The full-time employee who spends 60% of their 40 hours on R&D also contributes 1.0 × 60% = 0.6 FTE. Very close, but different.

The FTA will expect you to be able to justify both numbers. The part-time FTE should come from employment contracts or payroll records. The R&D time percentage should come from timesheets, sprint records, JIRA ticket time tracking, or another defensible time-allocation methodology. A blanket "all our engineers spend 80% of their time on R&D" will not survive audit without specific evidence.

The Mid-Year Crossing Problem

One of the most common scenarios we see: a company starts the year with 5 R&D staff, hires 10 more in Q3, and ends the year with 15. They assume they qualify for Tier 3 because they "have 15 R&D staff at year end."

They do not. Tier 3 requires an average of at least 14, not an end-of-period count of 14.

Let's run the math. With 5 staff for two quarters and 15 staff for the other two quarters:

> Average = (5 + 5 + 15 + 15) / 4 = 10

That is a Tier 2 company, not a Tier 3 company. The hiring was real and the commitment was real, but the average is what counts.

The planning implication is: if you are close to a threshold, the timing of hiring matters as much as the final headcount. A hire in January counts for 12 months. A hire in September counts for 4 months. Companies that want to qualify for a higher tier need to front-load their R&D hiring in the tax year, not back-load it.

The Staff Register Requirement

All of the above calculations assume you actually have a staff register you can rely on. Cabinet Decision No. 215 Article 9.1 requires the entity to maintain records sufficient to demonstrate eligibility, and keeping a monthly R&D staff register is one of the most practical ways to do that.

In practice, a monthly staff register is a spreadsheet or database with one row per employee per month, recording:

• Employee identifier
• Month
• R&D active flag (yes or no)
• R&D time percentage (0-100)
• FTE equivalent (0.0 to 1.0)
• UAE location confirmation (yes or no)
• Supervision and control confirmation (yes or no)
• Monthly gross compensation for the staff cost calculation
• Any stock option exclusion flag

The register is cumulative. At the end of the tax period, you use it to calculate both the threshold test (average monthly FTE) and the staff cost claim (sum of compensation for R&D-active, UAE-located, supervised staff, excluding stock options, with a 30% uplift for overheads).

Without this register, you cannot pass either test. Reconstructing it at year end from memory is not acceptable.

The 30% Staff Cost Uplift

Separate from the headcount threshold, Ministerial Decision No. 24 Article 8.3 provides a 30% uplift on qualifying staff costs. This is not a rate bonus; it is an increase to the expenditure base before the tiered rates are applied.

For example, if your qualifying R&D staff costs are AED 800,000 (after excluding stock options), the 30% uplift brings this to AED 1,040,000 before the credit is calculated. The uplift is intended to approximate the overhead costs (facilities, utilities, administrative support) that are otherwise not directly claimable.

The uplift applies regardless of which tier you reach. It compounds with whatever rate tier your headcount unlocks. The combination of the tiered rates and the uplift creates a meaningful incentive to build substantial UAE-based R&D teams rather than claim on small headcounts.

Stock Options and the Exclusion

Ministerial Decision No. 24 Article 8 excludes stock option compensation from qualifying staff costs. This is worth highlighting because many startups and scale-ups have significant equity components in their compensation packages.

The exclusion applies to:

• Vesting of stock options or restricted stock units
• Cash-settled equity instruments
• Employee share purchase plans where the discount is a form of compensation
• Any equity-linked bonus that is paid via equity rather than cash

It does not apply to:

• Base salary
• Cash bonuses
• Benefits in kind (medical insurance, pension, gratuity)
• Allowances (housing, transport)

If a portion of an employee's total compensation was equity, you subtract that portion before calculating the qualifying staff cost for that employee. Over time, this can be a material exclusion for founder-heavy tech companies.

Tax Group Aggregation

For entities that are members of a UAE Tax Group, the staff thresholds are measured at the Tax Group level, not the individual member level. If a parent entity has 8 R&D staff and a subsidiary has 10, the aggregated Tax Group has 18 R&D staff and qualifies for Tier 3.

This is one of the genuine advantages of a Tax Group structure for R&D-intensive corporate groups. Individual entities that would only qualify for Tier 1 or Tier 2 on their own can access Tier 3 rates when their headcounts combine.

However, intra-group recharges are specifically excluded under Ministerial Decision No. 24 Article 8.11. Staff costs paid by one Tax Group member to another do not count. The same employee cannot be counted twice.

The Planning Implication

Understanding the thresholds is the first step. Planning around them is the second.

If you are close to a threshold at your current headcount, three things can help:

• Hire earlier in the tax year so the new staff contribute to more monthly averages
• Audit your R&D time apportionment to make sure you are not underclaiming on employees whose R&D time is being miscounted
• Consider Tax Group consolidation if you have multiple UAE entities with R&D activity below their individual thresholds

If you are far below a threshold, the decision is different. A genuine commitment to grow the R&D team in the UAE may be worth more than gaming the current year's claim. The credit is designed to reward substantial, ongoing R&D investment, not to catch companies that cannot meet even the minimum staff requirement.

The 2, 6, 14 thresholds are not arbitrary. They reflect a policy intent to support entities with meaningful R&D headcount in the UAE. Companies that build real teams and track them honestly will benefit. Companies that try to shortcut the math will find the FTA's audit rules will catch them.

Track your staff register monthly. Do the calculation honestly. Plan your hiring against the thresholds, not around them.
