Corporate Tax UAE 2026: What Every Business Owner Needs to Register and File

Under Federal Decree-Law No. 47 of 2022, corporate tax in the UAE became effective for financial years starting on or after June 1, 2023 — the country’s first federal income tax on business profits. The Federal Tax Authority administers the regime through EmaraTax. Because the law is federal, corporate tax in Abu Dhabi, Dubai and every other emirate runs on one rulebook, one portal and one set of deadlines. Since then, the framework has been refined by a steady stream of Cabinet Decisions and Public Clarifications.

One naming point before we start, because it trips people up in search. Corporate income tax UAE, company tax, corporation tax and corporate tax all describe the same federal charge on business profits. There is only one, and the corporate tax law UAE businesses file under is Federal Decree-Law No. 47 of 2022 together with the Cabinet and Ministerial Decisions issued beneath it.

This guide to corporate tax in UAE is about the obligations rather than the arithmetic: who must register (and by when — the corporate tax registration deadline rules have their own guide), when your filing and payment fall due, and how the corporate tax penalty schedule shapes the way you plan the year. It reads the same whether your licence was issued in Dubai, Abu Dhabi or any other emirate, because the law is federal.

For the bracket arithmetic itself — how the bands work and what the threshold does — see the dedicated guide to the UAE corporate tax rate. If you want the work handled rather than explained, our corporate tax services in UAE team prepares registrations, returns and voluntary disclosures end to end.

Who actually has to register?

Registration is the part most UAE businesses get wrong. The base rule is simple: every taxable person registers, files a return, and keeps records, whether or not they owe a single dirham. Sitting in the 0% band, claiming Small Business Relief or qualifying as a free zone person does not remove the obligation. It only changes the calculation on the return itself.

Mandatory registrants include mainland LLCs, sole establishments and civil companies; free zone entities, including those eligible for the 0% qualifying rate; foreign companies with a UAE permanent establishment; natural persons earning business income above AED 1 million in a calendar year (covered in our guides to corporate tax for freelancers and sole establishments in the UAE and corporate tax for sole proprietors in the UAE); and members of a tax group (registered by the representative member). Conditionally exempt entities (Qualifying Public Benefit Entities, Qualifying Investment Funds and wholly government-owned companies) still register first and claim the exemption second.

A dormant holding company with no revenue still registers. So does a free zone trader reporting only qualifying income, and so does the consultancy that’s elected Small Business Relief. The single most common mistake we see in corporate tax services onboarding is a founder assuming that “no tax” means “no filing.” It never does, and the AED 10,000 penalty for that assumption is entirely avoidable.

Registration uses the EmaraTax portal and takes about an hour for a clean trade-licence file. It ends with a corporate tax TRN that is distinct from your VAT TRN. Store both. Every future return, FTA query and voluntary disclosure references one or the other.

Corporate tax registration in the UAE, step by step

Corporate tax registration in the UAE runs entirely through EmaraTax, the FTA’s online portal, and for a clean trade-licence file it is usually an hour’s work rather than a project. You sign in with the UAE Pass or EmaraTax credentials already linked to your VAT account, open the Corporate Tax tile, and start a new registration against the legal entity that holds the licence.

The portal asks for the trade licence, the Emirates ID and passport of the owners or authorised signatory, the Memorandum of Association or equivalent, and the entity’s contact and financial-year details. Free zone companies attach their free zone licence and, where relevant, proof of their registered activities. Once you submit, the FTA reviews the application and issues a corporate tax registration number — a TRN distinct from the one you already hold for VAT.

A few points save rework. Match the legal name and licence number exactly to the trade licence, because a mismatch bounces the application. Choose the financial year carefully, since it fixes every future filing date. And note the deadline for submitting the application in the first place, which has its own timing rules set out in our corporate tax registration deadline guide.

Two questions come up constantly at this point. The first is what the corporate tax registration last date actually is for an existing company: the original FTA cohorts, phased by the month the first trade licence was issued, have all now closed, so any business still unregistered is already late and should file immediately rather than wait. The second is what the UAE corporate tax registration deadline is for a new company, and there the answer is three months from the licence-issuance date.

Corporate tax registration UAE-wide runs on the same EmaraTax workflow whichever emirate issued the licence, so corporate tax in Dubai, Abu Dhabi and Sharjah all start from the same screens. If any of that reads as more admin than you want to take on, our corporate tax services in UAE team can prepare your registration file and guide you through the EmaraTax submission.

What you will actually be assessed on in 2026

Nothing in the assessment has changed for 2026: taxable income up to AED 375,000 is still charged at 0% and the balance at 9%. The 9% headline is a band, not a flat rate, and the AED 375,000 zero band applies to every taxable person regardless of size or sector. The bracket mechanics, the worked marginal calculations and the emirate-by-emirate position are set out in full in our dedicated guide to the UAE corporate tax rate — this section is only the summary you need to plan the filing.

Taxable income	Rate
Up to AED 375,000	0%
Above AED 375,000	9%
QFZP qualifying income	0%
Large MNEs (EUR 750m+ consolidated revenue)	15% under DMTT

9%

The Domestic Minimum Top-Up Tax applies only to multinational enterprise groups with consolidated revenue of at least EUR 750 million in two of the four preceding financial years. Domestic SMEs and free zone companies below that threshold continue to be assessed under the standard 9% and 0% regime. The 9% band is also the number UAE companies carry into regional comparisons — Saudi Arabia, by contrast, levies 20% corporate income tax on foreign-held shares, a gap unpacked in our guide to business setup in Saudi Arabia from the UAE.

For a complete picture of who falls outside the regime entirely — extractive businesses, certain investment funds and qualifying public benefit entities — see our UAE corporate tax exemptions guide and the companion breakdown of corporate tax exempt persons in the UAE. Operators looking to lower their effective rate within the rules can review how to reduce corporate tax in the UAE legally before quarter-end.

Corporate tax in Abu Dhabi: the same federal rules as Dubai

Corporate tax in Abu Dhabi works exactly the way it does in Dubai, because the regime is federal rather than emirate-level. Federal Decree-Law No. 47 of 2022 applies across all seven emirates, so a company licensed in Abu Dhabi faces the same 0% band up to AED 375,000, the same 9% rate above it, the same nine-month filing window, and the same EmaraTax registration process as one licensed in Dubai or Sharjah. There is no separate Abu Dhabi corporate tax rate, and no local surcharge sitting on top of the federal figure.

The one detail worth flagging is the free zone question. Abu Dhabi’s financial free zone, the Abu Dhabi Global Market (ADGM), is treated like any other UAE free zone for tax: a company based there can claim the 0% Qualifying Free Zone Person rate on qualifying income, provided it meets the substance, audit and transfer-pricing conditions that apply everywhere else — the same tests set out in our free zone corporate tax UAE guide. Mainland Abu Dhabi companies follow the standard 9% path.

So if you run a business in the capital, plan around the federal rules described throughout this guide. The registration deadline, the seven-year record-keeping period and the federal penalty schedule all read the same in Abu Dhabi as they do anywhere in the country.

Company tax in the UAE: what a limited company actually pays

Company tax in the UAE and corporate tax describe the same thing — there is one federal tax on business profits, and the two terms are interchangeable in everyday use. So when owners search for company tax in the UAE, the answer is the corporate tax regime set out here: 0% on the first AED 375,000 of taxable profit and 9% on the rest.

For a typical mainland LLC, that plays out gently at the smaller end. A company with AED 500,000 of taxable income pays nothing on the first AED 375,000 and 9% on the remaining AED 125,000 — a bill of AED 11,250, an effective rate of roughly 2.3% on total profit. The UAE corporate tax rate for 2026 has not moved from these figures. A company whose gross revenue stays at or below AED 3 million can go further and elect Small Business Relief, cutting the calculated tax to zero for that period. You can test your own numbers in our UAE corporate tax calculator before you file.

Holding companies, dormant entities and free zone companies all count as companies for this purpose, and all register, even where the eventual tax is nil. The practical takeaway: the label you search under does not change the obligation. Every company registers, and most pay far less than the 9% headline suggests.

About that AED 375,000 zero band

The AED 375,000 threshold is not an exemption from the corporate tax UAE regime. It is the first slice of taxable income on which the rate is 0%. Anything above it carries the 9% standard rate. You still register, still file, and still maintain seven years of records — even if every dirham of profit fits inside the zero band.

If you want the band explained properly — why it is marginal, how it behaves at AED 400,000 and at AED 1 million, and what happens to it in a free zone — that is the job of our guide to the corporate tax threshold and the brackets that sit around it.

A common error: assuming the threshold pro-rates for a short first tax period. It does not. Whether your first period is nine months or twelve, the first AED 375,000 of taxable income still attracts 0%. Time-apportioning the band, which we still see in DIY calculations, overstates the tax liability and pulls real cash out of the business for no reason.

Small Business Relief, and who actually qualifies

Small Business Relief is the single most undervalued election in the corporate tax UAE framework. If your revenue for a tax period is AED 3 million or less — measured by gross revenue, not profit — you can elect Small Business Relief on the return.

The period’s taxable income is then treated as zero. No 9% calculation, no carry-forward losses generated, no general interest deduction limit to track.

The relief is an election, not automatic. You make the election in the tax return itself, individually for each tax period, and the relief is available for periods ending on or before December 31, 2029. A consultancy with AED 2.4 million of revenue and AED 320,000 of profit pays zero corporate tax on a properly elected period. Forget to tick the box and it pays the full computed liability.

Before assuming you qualify, run the numbers in our UAE corporate tax calculator and cross-check against our Small Business Relief checker. The relief stacks awkwardly with carried-forward losses (you lose them for elected periods) and is incompatible with QFZP status, so the maths matters more than the headline.

If you’re in a free zone, read this twice

Free zone entities are not exempt from corporate tax UAE registration or filing. What they may be eligible for is the 0% rate on qualifying income as a Qualifying Free Zone Person. That status is conditional and easy to lose.

A QFZP must derive qualifying income (broadly: trading with other free zone persons, qualifying distribution activities, ownership of intellectual property meeting nexus rules, and a defined list of other categories). It must also maintain adequate substance in the free zone, prepare audited financial statements, and apply arm’s-length transfer pricing.

Finally, it must stay within the de-minimis threshold for non-qualifying income — the lower of AED 5 million or 5% of total revenue.

Audited financial statements have been a condition of Qualifying Free Zone Person status since the regime began, so any free zone company relying on the 0% rate needs them — it is a standing obligation, not a new one. For a full eligibility walk-through, see our deep-dive on free zone corporate tax UAE and the Qualifying Free Zone Person 2026 checklist.

Worked example: AED 1.2m profit, end to end

The mechanics of the 9% corporate tax calculation are straightforward, but the adjustments separate compliant returns from costly ones. Accounting profit is the starting line, not the answer.

The path from net accounting profit to taxable income runs through three adjustments most SMEs underestimate — our guide to corporate tax deductions and taxable income in the UAE works each one through. First, add-backs of non-deductible items (administrative fines, 50% of entertainment, gifts above the per-recipient limit). Second, deductions of exempt income (qualifying dividends and foreign permanent-establishment profits where elected). Third, the application of carried-forward tax losses, capped at 75% of the current period’s taxable income.

A Dubai mainland trading company closes its year ending December 31, 2025 with:

• Accounting net profit: AED 700,000
• Non-deductible fine paid to a government body: AED 25,000
• Exempt dividend received from a UAE subsidiary: AED 50,000
• Prior-year loss carried forward: AED 75,000

Step	Amount
Net profit per accounts	AED 700,000
Add: non-deductible fine	+ AED 25,000
Less: exempt dividend	− AED 50,000
Adjusted taxable income	AED 675,000
Less: prior-year loss (capped at 75% of taxable income)	− AED 75,000
Final taxable income	AED 600,000
0% on first AED 375,000	AED 0
9% on remaining AED 225,000	AED 20,250
Corporate tax payable	AED 20,250

Ignoring the add-back of the non-deductible fine would understate tax by AED 2,250. Failing to claim the exempt dividend would overstate tax by AED 4,500. Both errors show up as risk flags in the FTA’s automated review.

“

Accounting profit is the starting line, not the answer. The 9% corporate tax UAE calculation lives in the adjustments — non-deductible expenses added back, exempt income stripped out, prior losses applied within the 75% cap. Skip any of these and you either overpay or invite an audit.

The filing calendar, end to end

Your deadline is nine months from the end of your financial year. The return submission and any tax payment fall on the same date. There is no split deadline, and the FTA does not grant extensions outside extraordinary circumstances. So the corporate tax return due date is not a fixed national date the way personal tax deadlines work in other countries — it moves with your own year-end, which is why corporate income tax filing for a December year-end company lands on 30 September while a March year-end company files on 31 December.

A practical timing point we flag in every onboarding: bank transfers that arrive after the deadline are treated as late payment, no matter when they were initiated. The 14% per annum late payment penalty under Cabinet Decision No. 75 of 2023 applies from the day after the due date, accruing monthly on the unpaid balance. Pay at least three business days early.

The AED 10,000 waiver is still on the table

The FTA launched a penalty waiver for businesses that missed the corporate tax UAE registration deadline. The mechanics are simple but precise:

• File your first return or annual declaration within seven months from the end of your first tax period.
• The waiver is automatic — no separate claim.
• If you already paid the AED 10,000 fine and then file within the window, the FTA refunds it to EmaraTax.
• The waiver covers mainland businesses, free zone entities, exempt organisations, registered natural persons and tax group members.

The penalty framework — and what changes on 14 April 2026

Every UAE corporate tax penalty has had its own schedule since the regime began, separate from the VAT one. Cabinet Decision No. 75 of 2023 has set the figures below since August 1, 2023, and they do not change in 2026. What arrives on April 14, 2026 is Cabinet Decision No. 129 of 2025, which restructures the VAT, excise and tax-procedure penalties — cutting the old compounding late-payment charge to a flat 14% per annum and easing return-error and voluntary-disclosure fines — to bring them into line with the corporate tax methodology already in force. If you file VAT as well as corporate tax, that alignment is the change to note; your corporate tax penalties themselves stay put.

Violation	Corporate tax penalty (Cabinet Decision No. 75 of 2023)
Late registration	AED 10,000 fixed
Late return filing (months 1–12)	AED 500 per month (or part thereof)
Late return filing (month 13 onwards)	AED 1,000 per month
Late payment	14% per annum applied monthly on the unpaid balance
FTA-identified return error	15% fixed of tax difference + 1% per month variable
Self-corrected via voluntary disclosure	1% per month on the tax difference, no 15% fixed charge

The most cost-effective habit is to voluntarily disclose any known error in a past filing before the FTA finds it. Under Cabinet Decision No. 75 of 2023 self-correction already carries 1% a month on the tax difference, against a 15% fixed charge plus 1% a month once an audit notice lands — and that gap applies today, not from any transition date.

What we’d do, if we found a prior-period mis-classification today, is file the voluntary disclosure first and reconcile the cash later — the rate differential is that large. Our corporate tax voluntary disclosure UAE walks through the process. For the full federal-tax picture see UAE corporate tax penalties.

If you run more than one entity

UAE corporate tax allows two or more resident juridical persons to form a tax group, file a single consolidated return and offset profits and losses across qualifying members. The headline benefit is real — a profitable subsidiary can absorb losses from a sister entity in the same year, reducing the group’s effective rate.

But the conditions are strict, and the administration is heavier than most founders expect at the point of election.

The parent must hold at least 95% of the share capital, voting rights and entitlement to profits of each subsidiary, directly or indirectly. All members must be UAE-resident, share the same financial year, and apply the same accounting standards. A QFZP cannot sit inside a tax group while claiming 0% on qualifying income — the two regimes are mutually exclusive on that election.

Public Clarification CTP007, issued in 2025, requires every UAE tax group — regardless of revenue — to prepare Aggregated Financial Statements audited under International Standards on Auditing for tax periods starting on or after January 1, 2025. That requirement now catches small groups that previously sat below any audit threshold.

Before electing, model the consolidated picture in our UAE corporate tax grouping guide and weigh the audit cost against the loss-offset benefit.

Where the FTA is looking in 2026

The FTA is no longer in its early, awareness-focused phase. Its 2024 Annual Report records 93,000 inspection visits, a 135% increase year-on-year. Audits are now data-driven. FTA systems automatically cross-reference VAT return figures against corporate tax return revenue, and a mismatch triggers a risk flag with no manual intervention.

From what we’ve seen, the businesses most likely to attract attention share a short list of traits. A significant gap between VAT taxable supplies and CT reported revenue is the big one. Then there are free zone entities claiming 0% status with no real substance documentation behind it, and companies running sizeable related-party transactions without a single transfer-pricing record to show for them.

Late registrants, or businesses with a pattern of late filings, also draw scrutiny, as do entities reporting consecutive years of losses without clear commercial justification.

With UAE e-invoicing rolling out from 2026, the FTA will have real-time transaction-level visibility into participating businesses. Clean, consistent records across all filings are the foundation of defensible compliance, not a nice-to-have.

Two cycles of clean VAT-versus-CT reconciliation, a documented transfer-pricing position and an audit trail back to source invoices: that’s what an FTA officer expects to see when opening your file. If a notification does arrive, the stage-by-stage process — from selection engine to final assessment, with the document lists auditors actually send — is mapped in our FTA tax audit UAE guide.

The specialist regimes bolted onto the 9% framework

The core regime covered in this guide is only the base layer for some businesses. Four adjacent rulebooks decide the final number in specific situations, each with its own guide:

• UAE small business relief — the 0% election for businesses under AED 3 million revenue, available for periods up to 31 December 2029, with permanent-breach rules worth understanding before you rely on it
• UAE interest limitation rules — the 30%-of-EBITDA cap on net interest deductions for leveraged businesses above the AED 12 million de minimis
• UAE domestic minimum top-up tax — the 15% Pillar Two floor for entities inside multinational groups with EUR 750M+ consolidated revenue, live since January 2025
• UAE country-by-country reporting — the jurisdiction-level filing for groups above AED 3.15 billion, whose data feeds both foreign tax authorities and the FTA’s own risk engine

Most SMEs need only the first two; anyone inside a large group needs all four read together.

Where we see SMEs slip up

The registration window is the one people miscount most often. It’s three months from the exact trade-licence date, not the end of that month, and missing it by even a day triggers the AED 10,000 fine. Close behind is the assumption that free zone companies don’t have to file — every free zone entity registers and submits an annual return, including the ones on the 0% rate.

Record-keeping is another. The framework mandates a seven-year retention period for all financial records, and gaps in that trail become an audit liability the moment an officer opens the file. Then there’s reconciliation: the FTA compares your VAT and CT revenue figures directly, and an unexplained discrepancy between the two is among the most reliable audit triggers we see.

Transfer pricing gets overlooked too. Related-party transactions need arm’s-length documentation, revenue above AED 200 million pulls in a Master File and Local File, and a disclosure form summarising material related-party transactions goes in with the return regardless of size. On timing, plenty of founders confuse the seven-month waiver with the nine-month payment deadline — both apply at once, the waiver covers only the first return, and payment timing doesn’t budge. And the quiet one that costs real money is forgetting to re-elect Small Business Relief. The election is per-period, so a consultancy that elected it last year and forgot this year can walk straight into a 9% bill it didn’t budget for.

Velmont’s take, if you’re starting today

If you have not yet registered, do that this week — before the three-month window from your trade-licence date expires. The registration penalty is avoidable; once issued it becomes significantly harder to reverse.

If you are already registered, pin your nine-month filing and payment deadline. Build in time to prepare your accounts, work through the add-backs and exempt-income adjustments, apply any carried-forward losses within the 75% cap, and submit through EmaraTax with at least a week of buffer.

If you have related-party transactions, an outstanding backlog of prior periods or a free zone structure, get those elements reviewed and corrected sooner rather than later. Under Cabinet Decision No. 75 of 2023 a voluntary disclosure already costs a fraction of what an FTA-detected error does — 1% a month against 15% plus 1% a month — so the saving comes from moving before the FTA does, not from any calendar date.

Audit-ready bookkeeping services in Dubai and a clear picture of your VAT-versus-CT figures are the two most cost-effective investments ahead of the next filing cycle. Founders setting up a new business should follow our bookkeeping for startups in Dubai playbook.

If your corporate tax filing UAE deadline is approaching, or you are dealing with prior-period gaps, our corporate tax advisory service can take the process off your plate.

One word on choosing help. Plenty of businesses only look for a corporate tax consultant in the UAE in the month before the deadline, and by then the options narrow to whoever has capacity. The corporate tax advisors worth engaging want to see the ledger months earlier, because most of what determines the final number — the add-backs, the related-party pricing, the free zone revenue split — is decided during the year, not at filing. Good corporate tax advisory services are therefore a bookkeeping conversation before they are a tax one.
