The 9% Regime and Who It Applies To

The UAE introduced federal corporate tax for financial years starting on or after 1 June 2023. The structure is deliberately simple on the surface: the first AED 375,000 of taxable profit is taxed at 0%, and everything above that is taxed at 9%. A company with AED 500,000 in taxable profit pays 9% on AED 125,000 — roughly AED 11,250 — not on the whole amount.

This applies to essentially every business operating in the UAE, whether mainland or free zone, whether locally owned or foreign-owned. Corporate tax is charged on accounting profit with certain adjustments, not on revenue, so a startup that is burning cash and running at a loss owes nothing — but it still has obligations. The rate is one of the lowest headline corporate tax rates in the world, which is precisely why founders underestimate it: 9% feels negligible until it lands on a profitable year during a fundraise, when investors are modelling your net margins and want to see the tax line handled correctly.

The point for early-stage founders is not the rate. It's that the UAE now has a corporate tax system at all, with registration, filing, and record-keeping duties that exist regardless of whether you owe a dirham.

Qualifying Free Zone Person (0%) Explained

The headline benefit that keeps free zones attractive is the 0% rate on "qualifying income" for a Qualifying Free Zone Person (QFZP). But 0% is not automatic just because you hold a free zone licence. To be a QFZP and keep the 0% rate, a company must meet all five conditions: maintain adequate substance in the UAE (real people, real premises, real activity — not a mailbox), earn "qualifying income" as defined by the regime, satisfy the de minimis test that caps non-qualifying revenue, not elect to be taxed at the standard rate, and comply with transfer-pricing and arm's-length rules.

Fail any one of those conditions and the company loses QFZP status — and then the standard 0% / 9% rates apply to its taxable income above AED 375,000, often for that tax period and potentially beyond. This is the detail founders miss when they pitch their free zone company as permanently tax-free. The 0% is conditional, ongoing, and testable. A free zone company that sells mostly to other free zone or foreign businesses, keeps genuine operations in the zone, and stays within the de minimis limits can legitimately sit at 0%. One that drifts outside those lines cannot.

Small Business Relief

For genuinely early-stage companies, the most useful provision is Small Business Relief. If your revenue is AED 3 million or less in the current and all previous relevant tax periods, you can elect to be treated as having no taxable income — effectively 0% corporate tax — even if you're technically profitable. It's designed to keep compliance light for young, small businesses.

Two things make this urgent in 2026. First, the relief is temporary: it applies to tax periods ending on or before 31 December 2026, and no extension has been announced. After that date, the standard 0% / 9% rates apply to everyone. Second, the AED 3 million threshold is cumulative and unforgiving — once your revenue crosses AED 3 million in any single tax period, you can never reclaim Small Business Relief, even if revenue later falls back below the line. It also does not apply to Qualifying Free Zone Persons or to members of multinational enterprise groups. If you're relying on this relief in your financial model, model the cliff edge, not just the current year.

Mainland-Client Income and the 9% Trigger

Here is the trap that catches free zone founders most often. Your free zone company's 0% rate depends on the nature of your income. Revenue earned from transactions with mainland UAE customers is generally not "qualifying income," and if that mainland-facing revenue exceeds the de minimis threshold, it can jeopardise your entire QFZP status — pushing you onto the 9% standard rate rather than just taxing that slice.

In practice this means a founder who set up in a free zone to stay at 0%, then landed a large contract with a Dubai mainland client, may have quietly changed their tax position without realising it. The lesson is to map your customers before you optimise your structure. If most of your revenue will come from mainland UAE businesses, a free zone's 0% promise may not survive contact with your actual sales pipeline, and a mainland structure (which is straightforwardly subject to 9% above AED 375,000) may be simpler and more honest. Decide based on who you sell to, not on the brochure.

Registration and Filing Basics

Regardless of your rate, corporate tax registration is mandatory. Every taxable business must register with the Federal Tax Authority and obtain a Corporate Tax Registration Number — this is separate from any VAT registration. Registration is required even if you expect to owe nothing, and even if you intend to claim Small Business Relief, because the relief is an election you make on a return you must file.

The core obligations are: register on time through the FTA's EmaraTax portal, maintain proper accounting records that support your taxable-income calculation, file a corporate tax return within nine months of the end of your tax period, and elect any relief (like Small Business Relief) on that return rather than assuming it applies automatically. Missing the registration deadline carries administrative penalties, and "we were a loss-making startup" is not a defence against a filing obligation. Build the calendar into your operations from day one; it's far cheaper than remediating late.

Frequently Asked Questions

Is the UAE still tax-free for startups in 2026? No. The UAE has a 9% corporate tax on profits above AED 375,000 for financial years starting on or after 1 June 2023, plus 5% VAT. There are genuine 0% routes (Qualifying Free Zone Person status, Small Business Relief), but "tax-free" as a blanket claim is outdated and shouldn't appear in your investor materials.

My startup is losing money — do I still need to register? Yes. Corporate tax registration is mandatory for taxable persons regardless of profitability. You won't owe tax on a loss, but you must register with the FTA, keep records, and file a return by the deadline.

Does my free zone company automatically pay 0%? No. You must meet all five Qualifying Free Zone Person conditions — adequate substance, qualifying income, the de minimis test, no election for standard rates, and transfer-pricing compliance. Fail one and the standard rates apply.

What happens after Small Business Relief expires? For tax periods ending after 31 December 2026, the relief is no longer available (as of now, no extension has been announced), and the standard 0% / 9% rates apply to all taxable persons based on profit.

Can selling to a mainland client cost me my 0% rate? It can. Mainland-sourced revenue is generally non-qualifying income; if it exceeds the de minimis threshold it can jeopardise your QFZP status and push you onto the 9% standard rate. Map your customer base before choosing or defending a free zone structure.

Get Your Tax Position Right Before It's a Problem

Corporate tax is now a line investors read, a status that free zone founders can accidentally break, and a relief that's about to expire. If you're raising, restructuring, or signing your first big mainland contract, the time to check your position is before it shows up in someone else's diligence.
