Corporate Tax in the UAE is a federal tax on business profit, charged at 0% on taxable income up to AED 375,000 and 9% on taxable income above that threshold.

It was introduced by Federal Decree-Law No. 47 of 2022 and applies from the first financial year beginning on or after 1 June 2023. The rate and the threshold were set by Cabinet Decision No. 116 of 2022. It is charged on your net taxable profit, never on turnover.

Corporate Tax Is Not VAT, and That Distinction Costs People Money

The confusion between VAT and Corporate Tax is the entry point for almost every first conversation I have.

VAT is indirect: your business is the collection agent, charging it, recovering it on inputs, netting off and settling the difference. Corporate Tax is direct, a charge on the profit of the business itself, and nothing passes through.

The consequence catches people who are wired to think in VAT terms:

• Registration is not threshold-based. The obligation exists regardless of income or profit, so “I have not crossed a threshold” is not a defence.
• Filing is not optional at 0%. A business inside the 0% band, one electing Small Business Relief, and a free zone entity on qualifying income all still file.
• The tax reaches into your structure. VAT is largely mechanical; Corporate Tax touches how you hold assets, how profit moves between entities, and how related parties are documented.

That last point is the one I would underline. UAE businesses were built in a zero-tax environment, and the structures that made complete sense then do not always make sense now.

UAE Corporate Tax Rates and Thresholds

Three rate positions cover almost every business I see in Abu Dhabi.

The AED 375,000 threshold applies once across all of your business activities, not once per activity. Splitting a business to multiply the threshold falls squarely inside the general anti-abuse rule in Article 50 of the Corporate Tax Law.

How Your Taxable Income Is Calculated

Taxable income starts from your accounting profit and is then adjusted, in a sequence where every step depends on the one before it.

1. Start with accounting profit. Your financial statements must be prepared under IFRS, or under IFRS for SMEs if your revenue does not exceed AED 50 million, per Ministerial Decision No. 114 of 2023.

• Apply the statutory adjustments. Non-deductible expenses, the interest deduction limitation, and arm’s length corrections on related party transactions all move the number.
• Apply reliefs and exemptions. Small Business Relief, the participation exemption, and free zone qualifying income treatment are applied at this stage.
• Apply the rate. 0% up to AED 375,000 and 9% above it, with payment due in the same nine-month window as the return.

To sanity-check a figure before you speak to anyone, the corporate tax calculator gives a rough position. The real number depends on the adjustments, and the adjustments depend on the quality of your books.

Corporate Tax compliance rests on five obligations: register on time, keep books on the correct basis, price related party transactions at arm’s length, retain records, and file on time.

Each one is a separate exposure. Businesses rarely fail on the return itself, they fail on something upstream that the return then reports.

Registration and Deadlines

Every taxable person must register and obtain a Corporate Tax Registration Number, including businesses below AED 375,000 and QFZPs. Registration deadlines were set by FTA Decision No. 3 of 2024 and depend on the month your trade licence was first issued, not your profit.

Late registration carries a fixed AED 10,000 penalty under Cabinet Decision No. 75 of 2023, as amended by Cabinet Decision No. 10 of 2024. If you have not registered yet, start at corporate tax registration, not the return.

Accounting Basis and Financial Statements

This is where most of my work happens, and it is the requirement businesses are least aware of.

Under Ministerial Decision No. 114 of 2023, cash basis is permitted only where revenue does not exceed AED 3 million, or by application to the FTA in exceptional circumstances. Above that, accrual is mandatory, not a preference.

Even businesses already on accrual, the quality of that accrual is the real question. Failures that recur across my client files:

• Revenue recognised on invoice or cash receipt. IFRS 15 requires recognition against the performance obligation; the gap distorts taxable income directly.

• Accruals missing or estimated badly. End of service benefits, bad debt provisions and accrued liabilities are the usual casualties.

• Prepayments expensed in full. Amortising over the benefit period is not a nicety, it changes the profit you report and the tax you pay.

None of these are cosmetic, they either make you overpay Corporate Tax or leave you carrying an understatement into an audit window.

Related Party Transactions and Transfer Pricing

Transfer pricing is where I see the widest gap between what SMBs believe their obligations are and what the law requires. Most owners assume it is a large-group problem. It is not.

Every transaction with a related party or connected person must satisfy the arm’s length principle and be disclosed in the return. Formal documentation thresholds sit higher. Under Ministerial Decision No. 97 of 2023, a Master File and Local File are required at AED 200 million of revenue in the tax period, or at AED 3.15 billion of consolidated group revenue.

Below those thresholds the documentation obligation is lighter, but the arm’s length obligation is identical. Two companies sharing an owner do not get to move money on informal terms. More detail sits on the transfer pricing page.

From the Practice: The Intercompany Fee Dressed Up as Cash

A mid-sized group built around a mainland entity and an Abu Dhabi free zone subsidiary transacted regularly: management fees flowing free zone to mainland, and an intercompany loan running for years with no interest and no documentation.

The free zone entity was claiming QFZP status. The management fee arrangement had no transfer pricing policy, no benchmarking, no formal agreement, in substance an informal cash movement dressed up as a fee. The loan was equally exposed: no interest means a deemed benefit potentially taxable under arm’s length principles.

I mapped every intercompany flow, then built a transfer pricing policy: benchmarking the management fee against comparable arrangements, applying an arm’s length interest rate to the loan, and drafting formal agreements. I also prepared a Master File and Local File framework, since the group was approaching the AED 200 million mandatory documentation threshold.

The group kept its QFZP status and the arrangements became defensible under audit. Most Abu Dhabi SMB groups carry some version of this. Related-party transactions arise organically because two businesses share an owner, and money moves without anyone asking whether the terms would hold up to an arm’s length test.

Records and Documentation

Corporate Tax records must generally be retained for seven years after the tax period ends. The FTA does not ask you to attach evidence when you file, which is precisely why it has to exist.

The documentation most often missing when a business first comes into my office:

• Transfer pricing support. Intercompany arrangements running for years with no written agreement and no benchmarking behind them.

• Audit trails on provisions. End of service, bad debts and accruals recorded with nothing to substantiate the figure.

• Substance documentation. Nothing on file showing where the business is actually conducted.

• A written accounting policy. Mixed basis in the ledger and no document explaining the approach taken.

Businesses that struggle in an audit are not usually the ones with complex positions, they are the ones whose records do not support the return filed.

Corporate Tax Treatment by Business Type

The most expensive mistake I have seen a UAE business make with Corporate Tax was assuming it did not apply to them.

One client, registered this year, had been operating continuously since 2017, nearly eight years of real trading, real revenue, and no Corporate Tax registration. They were not hiding anything, they had assumed a new law could not reach back to an old business, and nobody had told them otherwise.

The fixed penalty was the easy part. What followed was six months of work and three years of accounts rebuilt: part cash, part accrual with no consistent logic, records missing across periods, no proper treatment of prepayments, accruals or end of service provisions.

What that reconstruction actually involved:

• Establishing a reliable opening position before the first CT-applicable period, so everything downstream had a defensible start.

• Rebuilding three years on a consistent accrual basis, including a balance sheet that had never properly existed.

• Timing every deductible provision correctly, rather than accepting what the ledger happened to show.

• Reconciling VAT returns against the reconstructed P&L, because inconsistency between the two is exactly what an inspector looks for.

The penalty for late registration is fixed and finite. The cost of cleaning up what accumulated behind it is not. Businesses that delayed did not only miss a deadline, they missed the window to make clean elections before the FTA had visibility.

Late is fixable. It simply costs more, in professional fees and in the adjustments that follow.

My work covers the full Corporate Tax cycle for mainland and free zone businesses: registration, computation, filing and post-filing support.

What that looks like depends on where your business actually is. A free zone entity approaching its first filing needs something different from a multi-entity group with five years of intercompany history to untangle.

Corporate Tax Registration

Registration is a legal step, not a tax outcome. I confirm your deadline against the licence issue date, prepare and submit the EmaraTax application, and identify anything in the history needing fixing before the first return. See corporate tax registration.

Return Filing and Payment Support

You have nine months from year end to file and pay. I prepare the computation, reconcile it to the financial statements, complete the related party disclosure, and file through EmaraTax. See corporate tax filing.

Free Zone and QFZP Review

The 0% rate is not a free zone benefit. It is a substance test, and it has to be demonstrated period by period.

I assess qualifying income, the de minimis position, and whether substance genuinely supports the claim. Where it does not, I say so before the FTA does. More on free zone corporate tax.

Small Business Relief

Relief is an election made on the return, not a status you hold. I check eligibility against current and prior periods, model whether electing is actually better, and make the election correctly.

Timing matters more than usual here. Under Ministerial Decision No. 73 of 2023, the relief runs only for tax periods ending on or before 31 December 2026. For most calendar-year businesses, the current period is the last one available. See small business relief.

Transfer Pricing and Related Party Documentation

I map every intercompany flow, benchmark the pricing, draft the intercompany agreements, and build the Master File and Local File framework where the thresholds are met or approaching. Detail on transfer pricing.

Penalty Exposure and Voluntary Disclosure

Where something has already gone wrong, the question is how to correct it on the best terms available. I quantify the exposure, prepare the voluntary disclosure, and handle the correspondence. See corporate tax penalties.

Corporate Tax rarely arrives on its own. Where the books need rebuilding first, that runs through accounting services. Where VAT positions need reconciling, through VAT services. Where the financial statements need auditing, through audit services.

Every engagement in my practice follows the same five steps, in this order, because each one depends on the last.

Five things I tell every client, drawn from the mistakes I see most often.

• Fix the accounting basis before the return. Above AED 3 million on cash basis is not a suboptimal method, it is non-compliant, and the longer it runs the harder remediation gets.

• Treat Small Business Relief as an election, not a status. I have had clients assume the relief was permanent. It is assessed every tax period, and breaching AED 3 million once removes eligibility for the periods that follow.

• Test your free zone substance honestly. Employees on the licence but working elsewhere, with no genuine decision-making inside the zone, is the pattern I meet repeatedly. Failing a QFZP condition costs the 0% rate for that period and the four that follow.

• Document intercompany arrangements before anyone asks. A management fee with no policy behind it and an interest-free related-party loan are the two exposures I find most often.

• File as if an audit is coming. The FTA does not request evidence at filing, but retention runs seven years. If you cannot support a position today, you will not be able to in year five either.

Honestly, real estate is the sector I find least prepared for Corporate Tax, and not for the reason most assume. The developers and brokerages I work with are commercially sharp; the problem is structural.

A Group Structure Nobody Designed for Tax

A typical Abu Dhabi real estate group: a mainland brokerage, maybe one or two project SPVs, a property management arm, sometimes short-term rental, each set up for a legitimate reason. Under Corporate Tax the question changes: do these entities form a tax group, are the intercompany transactions correctly priced, is the income in each entity actually what it appears to be?

VAT treatment already caused confusion, residential versus commercial, first supply versus subsequent supply, the margin scheme, and many businesses entered Corporate Tax with VAT positions already imperfect, which compound under CT. Revenue recognition is another layer: deposits, advances and staged payments that do not naturally line up with when IFRS 15 says income should be recognised.

The brokerage side has its own version: commission income frequently split between individuals, referral partners and related entities in ways never designed with tax in mind. Map those flows against arm’s length principles and things get uncomfortable quickly.

Why the Risks Stack Instead of Standing Alone

What makes real estate the most exposed sector is that multi-entity risk, transfer pricing risk, revenue recognition risk and VAT history risk all stack at once. Engineering firms have simpler revenue models, trading is more transactional, professional services tend to be lighter in structure. Real estate groups carry all of it simultaneously.

The businesses in the best shape treated Corporate Tax as a reason to clean up the whole group structure, not just file a return. The most exposed handed their books to an accountant in September and asked them to make it work.

The first conversation is a diagnostic, not a pitch. Bring your trade licence, your latest financial statements even if unaudited, a rough revenue figure for the last year, and whatever you hold on related parties, however informal.

That is enough for a meaningful conversation. Clients who arrive saying everything is in order are usually where my review finds the most to fix; clients who arrive unsure where they stand are the more useful conversations, because the starting point is honest.

The cost of a conversation is zero. The cost of getting this wrong compounds. Book a free consultation with AH Chartered Accountants, and I will tell you plainly what you are dealing with.
