Engineering and architecture consultancies operating through a UAE company must register for Corporate Tax and file annually, paying 9% on taxable income above AED 375,000. Unbilled work in progress counts in profit once recognised, and partner pay is deductible only at arm’s length. For a 31 December 2025 year end, the return and payment are due by 30 September 2026.
- Your firm provides structural, MEP, civil or architectural design and supervision services
- Partners or shareholders take salaries, director fees or profit distributions
- You bill on time spent, stage completion or a percentage of construction cost
- Your engineers work on projects in Saudi Arabia, Oman, Africa or elsewhere abroad

Does an engineering or architecture firm in the UAE need to register for Corporate Tax?
Yes, if the practice runs through a UAE company: it must register and file whatever its fee income. A licensed individual engineer or architect billing in their own name registers only once business turnover exceeds AED 1M in a calendar year, by 31 March of the following year.
The thresholds below are the ones consultancies ask about most, as of September 2026.
| Practice structure | Corporate Tax | VAT |
|---|---|---|
| Mainland consultancy LLC | Registers and files; 9% on taxable income above AED 375,000 | Mandatory once taxable supplies pass AED 375,000 |
| Small practice with revenue up to AED 3M | Can elect Small Business Relief for periods ending on or before 31 December 2029, still files | Relief has no effect on VAT |
| Free zone design office serving UAE developers | Mainland client income is generally non-qualifying, so 0% rarely applies | 5% on services to UAE clients |
| Freelance engineer or architect | Registers once turnover exceeds AED 1M in a calendar year; return due 30 September | Voluntary registration from AED 187,500 |
| Practice billing clients outside the GCC | Fees are part of taxable income | Exported services can be zero-rated |
A consultancy that has just started or has won no projects yet still files a return for each tax period once registered. Our comparison of Corporate Tax for freelancers helps if you are choosing between a personal licence and a company.
How is unbilled work in progress taxed for an engineering consultancy?
Unbilled work in progress is taxed in the year it is recognised as revenue in your accounts, because taxable income starts from accounting profit. Hours your engineers logged on a tower design in December 2025 but invoiced in February 2026 generally belong to 2025 if the work had been performed and the fee earned.
Time-based, stage-based and percentage fees
Consultancy contracts price work in different ways, and each creates a different WIP question at year end.
| Fee basis | Typical contract | Year-end WIP question |
|---|---|---|
| Time and materials | Hourly or man-month rates for design reviews and site supervision | Which logged hours are billable but not yet invoiced? |
| Stage completion | Concept, schematic, detailed design, tender, supervision | How far through the current stage is the team? |
| Percentage of construction cost | Architect’s fee as a share of project value | What share of the fee matches work delivered so far? |
| Lump sum | Fixed fee for a defined design package | Is the deliverable complete, partly complete or not started? |
Valuing WIP you can defend
Base WIP on timesheets, stage reports and fee schedules, and reduce it where a client dispute or fee cap means the hours will never be billed. Overstated WIP inflates profit and tax; ignored WIP understates it and makes the return incorrect. Our bookkeeping guide for consultancies shows how to run time billing and WIP month by month.
How do partner pay, PI insurance and overseas projects affect a consultancy's Corporate Tax?
Partner salaries are deductible only at a market rate, business running costs such as professional indemnity cover are generally deductible, and work abroad can create tax exposure in the project country as well as in the UAE.
Partner remuneration versus profit extraction
In a UAE consultancy LLC the partners are usually shareholders, and often directors too. Anything the firm pays them, whether salary, director fees, housing or car allowances, is a payment to a connected person. It is deductible only to the extent it matches what the firm would pay an unrelated engineer or architect for the same role, and it goes on the transfer pricing disclosure form filed with the return. Amounts above that level are added back to taxable income.
Dividends are different: they are a distribution of profit after tax, not an expense. The choice between salary and dividends is covered in UAE profit extraction for founders.
| Payment to partner | Deductible? | Evidence to keep |
|---|---|---|
| Salary for a real engineering or management role | Yes, at an arm’s length rate | Employment contract, role description, market salary comparison |
| Director fees | Yes, at an arm’s length level | Board resolution and basis for the amount |
| Drawings taken from the bank as needed | No, unless formalised as salary or a loan | Recorded against the partner’s current or loan account |
| Dividends | No, they come out of after-tax profit | Shareholder resolution |
Professional indemnity, licences and software
Costs incurred wholly for the practice, such as professional indemnity insurance, Dubai Municipality or other engineering authority registrations, trade licence renewal and design software subscriptions, are generally deductible. Keep policies and invoices for 7 years. Read deductible expenses under UAE Corporate Tax for items that are restricted or blocked.
Overseas projects and permanent establishment risk
Under UAE law a permanent establishment is a fixed place of business or a dependent agent who habitually concludes contracts, and the FTA looks at the facts rather than the licence. Other countries apply their own tests, so a site office in Riyadh or engineers stationed in Muscat for months can create a taxable presence there. Your UAE company is still taxed on that project’s profit at home, so record foreign taxes paid and take advice on relief before filing. See permanent establishment and UAE Corporate Tax.
How does an architecture or engineering firm file its Corporate Tax return?
Most of the effort goes into WIP and partner pay; the EmaraTax submission is the final hour.
Lock timesheets at 31 December 2025
Close the time system and export hours by project, stage and staff member.
Value unbilled WIP per project
Apply contract rates or stage percentages to unbilled work and write down anything unlikely to be billed.
Review partner and director pay
Compare salaries, fees and allowances to market levels and prepare the connected-person figures for disclosure.
Check overseas project costs
Separate foreign site costs, withholding or foreign taxes suffered and any local registrations abroad.
Finalise accounts and taxable income
Start from accounting profit, add back non-deductible items and any above-market partner pay, then apply the 0% band or Small Business Relief.
Complete the return on EmaraTax
Enter financial data, the transfer pricing disclosure and any relief election in the Corporate Tax return.
Submit and pay by 30 September 2026
Submit the return and settle the tax through EmaraTax before the deadline.
What records should a consultancy prepare for the Corporate Tax return?
Collect these before year-end work starts, and keep them for 7 years.
- Client appointment agreements and fee schedules for every live project
- Timesheet exports by project and stage at 31 December 2025
- Invoices issued and a list of fees billed after year end relating to 2025 work
- Partner and director contracts, board resolutions and payroll records
- Professional indemnity policies, engineering registrations and licence invoices
- Overseas project contracts, foreign tax receipts and local registrations
- Bank statements and partner current or loan account ledgers
- Trade licence, Corporate Tax registration and VAT certificates
What are the key tax deadlines for engineering and architecture practices?
For a practice with a calendar year, the next Corporate Tax return and payment are due on 30 September 2026.
| Date | What is due | For whom |
|---|---|---|
| 30 September 2026 | Corporate Tax return and payment for 2025 | Consultancies with a 31 December 2025 year end |
| 31 March 2027 | Corporate Tax registration | Freelance engineers and architects whose 2026 turnover exceeds AED 1M |
| 30 September 2027 | First Corporate Tax return for that 2026 freelance income | Same individuals |
| 28th of the month after each VAT period | VAT 201 return and payment | VAT-registered practices |
| 31 March 2027 | Appoint an e-invoicing Accredited Service Provider (go live 1 July 2027) | Practices with revenue under AED 50M |
What Corporate Tax penalties apply to engineering consultancies?
Consultancies are subject to the standard Corporate Tax penalties in Cabinet Decision 75/2023 as amended, and WIP and partner pay errors drive most incorrect return findings.
| Issue | Penalty (2026) | Consultancy example |
|---|---|---|
| Registered late | AED 10,000, waived if the first return is filed within 7 months of the first period end | Partners assumed a professional licence was outside Corporate Tax |
| Return filed late | AED 500 a month for 12 months, then AED 1,000 a month | Waiting for final client sign-off on stage fees |
| Tax paid late | 14% a year, calculated monthly | Cash held back for partner distributions |
| Incorrect return | From AED 500, plus 1% a month on the tax difference | Unbilled WIP left out, or partner salaries above market deducted |
| Records not kept | AED 10,000, or AED 20,000 for a repeat within 24 months | Timesheets deleted when the software was changed |
Here is how they combine for an illustrative Abu Dhabi structural engineering practice that owes AED 25,000 and files 7 months late: 7 x AED 500 = AED 3,500 for late filing and AED 25,000 x 14% x 7 / 12 = about AED 2,042 for late payment. If an FTA review then disallows AED 100,000 of above-market partner salary, the extra AED 9,000 of tax attracts 1% a month on top. See the UAE Corporate Tax penalties guide.
Worried a penalty is already running?
If your 2025 WIP or partner pay is still unsettled, a 15-minute call shows what the return needs and what filing after 30 September would cost.
6 mistakes engineering and architecture firms make with Corporate Tax
These are the issues we correct most often in consultancy returns.
- Unbilled WIP ignored. Leaving earned but uninvoiced fees out of 2025 understates profit, so any tax difference carries the incorrect return penalty and 1% a month.
- Partner drawings booked as salaries. Ad hoc withdrawals relabelled as payroll at year end cannot be supported as arm’s length pay and are added back.
- No transfer pricing disclosure for partner pay. Salaries and fees to shareholders and directors are connected-person payments that must be reported with the return.
- Overseas site teams not reviewed. Ignoring a possible taxable presence abroad leaves foreign tax unplanned and UAE records incomplete.
- Timesheets not retained. Without them WIP and fee income cannot be proven, which risks the AED 10,000 records penalty.
- Assuming a professional licence is exempt. Engineering and architecture companies are taxable persons like any other company, and registering late costs AED 10,000.
How can an engineering or architecture practice avoid penalties?
The practices that never pay penalties treat timesheets and partner accounts as tax records, not admin.
- Monthly: close timesheets by the 5th and calculate unbilled WIP per project
- Monthly: post partner withdrawals to current or loan accounts, never to payroll after the event
- Monthly: invoice completed stages promptly so WIP does not build up
- Quarterly: file VAT 201 by the 28th, separating zero-rated fees for clients outside the GCC
- Quarterly: review where overseas staff are working and for how long
- Annually: benchmark partner and director pay and record the basis in a board resolution
- Annually: choose Small Business Relief or the standard calculation before drafting
- Annually: have a qualified accountant review WIP, partner pay and the disclosure form before submission
Consultancy late on Corporate Tax or facing an FTA penalty?
File the late return first and pay the tax, since the monthly filing penalty and the 14% a year payment charge only stop when both are done.
Where a filed return missed WIP or deducted too much partner pay, submit a voluntary disclosure to correct it before the FTA opens an audit. If you believe a penalty was wrongly imposed, request reconsideration within 40 business days of the decision, and if that fails take the matter to the Tax Disputes Resolution Committee.
Use our missed Corporate Tax deadline checklist for the next few days, and the FTA reconsideration request guide if you are disputing a penalty.

Worked example: an illustrative Dubai architecture practice
An illustrative Dubai architecture and engineering practice has AED 2.4M of fee revenue for 2025, including correctly recorded unbilled WIP, and accounting profit of AED 520,000 after market-rate partner salaries. Revenue has never exceeded AED 3M.
| Line | Small Business Relief elected | Standard calculation | WIP of AED 180,000 left out (incorrect) |
|---|---|---|---|
| Fee revenue | AED 2,400,000 | AED 2,400,000 | AED 2,220,000 |
| Accounting profit | AED 520,000 | AED 520,000 | AED 340,000 |
| Taxable at 9% | AED 0 | AED 145,000 | AED 0 (below AED 375,000) |
| Corporate Tax | AED 0 | AED 13,050 | AED 0 declared, AED 13,050 actually due |
| Filed 4 months late | AED 2,000 penalty | AED 2,000 plus AED 609 late payment | Tax difference of AED 13,050 plus incorrect return penalty |
The third column shows why WIP matters. Omitting AED 180,000 of earned fees takes profit below AED 375,000 and the declared tax to zero, but if the firm has not elected Small Business Relief, the FTA can assess the AED 13,050 difference with penalties. Electing the relief correctly, as explained in our Small Business Relief guide, is the lawful way to reach nil.
DIY, freelance accountant or firm: which suits a consultancy's Corporate Tax?
A sole engineer with a few invoices can file personally; a partnership-style practice with WIP, partner pay and overseas work is better served by an accountant who reviews all three.
| Option | Cost | Partner time | Risk | Suits |
|---|---|---|---|---|
| Partners file themselves | No fee | High, taken from billable hours | High: WIP and connected-person errors | Single-partner practice with no WIP |
| Freelance accountant | Typical market range: below a firm, varies by complexity | Medium | Medium: transfer pricing often skipped | Small practice, UAE-only projects |
| Paci | Fixed quote within 24 hours; bookkeeping from AED 599/month | Low | Lower: qualified accountants review WIP, partner pay and disclosure | Multi-partner firms, overseas projects |

What engineering and architecture firm owners actually ask us
Questions from consultancy partners, with answers checked against the rules in September 2026.
Should our partners take a salary or just draw profits, and can the firm deduct what it pays them?
Either can work, but they are taxed differently. A salary for a real role is deductible at an arm’s length rate you can support, and is reported on the transfer pricing disclosure form with the return. Profit distributions are not deductible. Paying above the market rate and deducting it risks the excess being added back.
Our partners are also directors. Can the firm deduct director fees paid to them?
Director fees to partners are connected-person payments, so they are deductible only at a level you can justify against the market, backed by a board resolution, and they must appear on the transfer pricing disclosure form. The VAT position of director fees is a separate question worth checking with your accountant.
Can we deduct running costs such as PI insurance, licence renewals and software?
Costs incurred wholly for the business, such as professional indemnity cover, licence fees and design software, are generally deductible. Keep the invoices and policies for 7 years, the Corporate Tax record-keeping period, in case the FTA asks.
We are sending engineers to a project abroad. Does that create a taxable presence there?
It might. Under UAE law a permanent establishment is a fixed place of business or a dependent agent, judged on the facts. The project country applies its own test, so a site office or long stays by staff can create tax there. Review this before the team mobilises, not after year end.
If our engineers do the work outside the UAE, is our fee zero-rated for VAT?
Zero-rating for exported services depends mainly on the client being outside the GCC and the conditions for export being met, not simply on where your engineers sit. A UAE client usually means 5% VAT. Our guide to zero-rated exported services covers the tests.
I work as a freelance engineer billing over AED 1 million. Register for Corporate Tax or set up a company?
As an individual you must register once turnover passes AED 1M in a calendar year, by 31 March of the next year, with the return due 30 September. A company registers whatever its revenue. Either way 9% applies only to taxable income above AED 375,000, so the choice is more about liability and growth than rate.
How do we prepare when much of our fee income is unbilled WIP at year end?
Taxable income starts from accounting profit, so WIP recognised as revenue in the accounts is normally taxed in that year. Value it from timesheets and stage reports, and diary the filing: 30 September 2026 for a 31 December 2025 year end, with AED 500 a month for the first 12 months if late.
Frequently asked questions
How much Corporate Tax does an engineering company in the UAE pay?+
It pays 0% on the first AED 375,000 of taxable income and 9% on the rest. A consultancy with taxable income of AED 900,000 pays 9% x AED 525,000 = AED 47,250. With revenue up to AED 3M it can elect Small Business Relief instead and pay nothing, while still filing. Try the Corporate Tax estimator.
Do architecture firms in Dubai need to file Corporate Tax returns?+
Yes. Every architecture firm operating through a UAE company registers with the FTA and files a Corporate Tax return within 9 months of its year end, including loss years. For a 31 December 2025 year end that is 30 September 2026. Our Corporate Tax return filing guide walks through the process.
Is unbilled work in progress taxable for UAE consultancies?+
Work in progress that is recognised as revenue in the financial statements is part of accounting profit, which is the starting point for taxable income. So hours worked in 2025 and invoiced in 2026 are generally taxed in 2025 if the fee was earned. Value WIP carefully and write down fees that will not be billed.
Can an engineering consultancy use Small Business Relief?+
Yes, if it is a UAE resident company with revenue of AED 3M or less in the current and all earlier tax periods and it is not a Qualifying Free Zone Person. The relief is elected in the return, now runs to periods ending on or before 31 December 2029, and still requires a filed return.
Do engineering consultancies need audited financial statements for Corporate Tax?+
Ministerial Decision No. 84 of 2025 requires audited statements for tax periods starting on or after 1 January 2025 where revenue exceeds AED 50,000,000, and for every Qualifying Free Zone Person. Most small practices fall outside that, though a free zone authority or client may ask for audited accounts under its own rules.
Is profit from overseas engineering projects taxed in the UAE?+
A UAE resident company is taxed on its business profit, including profit from projects abroad. The project country may also tax that profit if the work creates a taxable presence there, so keep records of foreign tax paid and take advice on relief. Payments to connected entities abroad must also be at arm’s length.
