UAE Corporate Tax & Business Compliance: The Complete Guide

Running or launching a company in the UAE now means operating inside a real federal tax regime for the first time. For financial years starting on or after 1 June 2023, most businesses fall under Federal Decree-Law No. 47 of 2022. This guide maps the full compliance chain — corporate tax, VAT, beneficial ownership, economic substance and record-keeping — so you can see how each obligation connects to the next instead of meeting them one surprise at a time.

Direct answer. Yes — nearly every UAE business must now register for corporate tax and file a return, even inside the 0% band. Corporate tax is governed by Federal Decree-Law No. 47 of 2022, charged at 0% up to AED 375,000 of taxable income and 9% above it. This hub walks through who registers, how free zones and VAT fit in, and the disclosure and record rules that sit alongside them.

What the UAE corporate tax law covers

The centrepiece is Federal Decree-Law No. 47 of 2022, the federal corporate tax law that applies across all seven emirates. It taxes the profits of "Taxable Persons" — UAE-incorporated companies, foreign companies with a permanent establishment or place of effective management here, and natural persons carrying on a business in the UAE once their turnover crosses a set threshold in a calendar year.

Our plain-language breakdown of how corporate tax works goes deeper on residence, taxable income and exempt persons. This hub stays wider: it shows how corporate tax, VAT and the disclosure regimes interlock, because a UAE business rarely faces just one of them.

Corporate tax rates: the 0% and 9% bands

Corporate tax is charged at two headline rates: 0% on taxable income up to AED 375,000, and 9% on taxable income above it. That single step is the number most small businesses plan around, because it decides whether profit crosses into the 9% band at all.

You can model where your profit lands across the two bands with our corporate tax calculator. Two refinements sit on top of the headline rates. Small Business Relief lets a resident business with revenue at or below AED 3,000,000 elect to be treated as having no taxable income for a tax period — though this relief is time-limited, applying only to tax periods ending on or before 31 December 2026. And very large multinational groups may face a separate domestic minimum top-up tax under the global minimum tax rules — a 15% minimum effective tax rate for groups with consolidated annual revenue of EUR 750 million or more, effective for financial years starting on or after 1 January 2025.

Who must register — and by when

Registration is mandatory and separate from holding a trade licence. Every taxable person must register with the Federal Tax Authority and obtain a Corporate Tax Registration Number, even a business that expects to sit wholly within the 0% band. The 0% rate only reduces what you pay, not whether you must be on the register.

The Federal Tax Authority set staggered registration deadlines tied to the month a licence was issued, so the exact date is specific to each business and depends on the month your licence was issued — confirm the precise deadline that applies to your licence with the Federal Tax Authority. We keep the moving picture current in our guide to corporate tax registration deadlines. Missing your window exposes the business to an administrative penalty of AED 10,000, so registration is usually the first item a new company clears.

Free zone companies and the Qualifying Free Zone Person

Free zone companies are not automatically exempt — a common and costly misreading. A business keeps a 0% rate only as a Qualifying Free Zone Person (QFZP), and only on its "Qualifying Income", while it continuously satisfies a set of conditions: adequate substance in the free zone, income of a qualifying type, not electing the standard rate, compliance with transfer-pricing rules and documentation, and keeping any non-qualifying revenue within permitted de-minimis limits.

Breach any one of them and the business can lose QFZP status and be taxed at 9% on all of its income, potentially for several years — the exact de-minimis thresholds and the length of the disqualification period turn on the specific free-zone rules, so confirm them for your zone and activity. Income a free zone company earns from mainland UAE customers is also generally taxed at 9%. Either way, free zone entities must still register with the Federal Tax Authority and file returns like mainland companies.

VAT: a separate obligation you can't fold into corporate tax

Corporate tax does not replace VAT, and the two run on completely separate tracks. Value Added Tax under Federal Decree-Law No. 8 of 2017 (as amended) is charged at a standard rate of 5% on most goods and services. VAT registration becomes mandatory once a business's taxable supplies and imports exceed AED 375,000 over the previous twelve months (or are expected to in the next thirty days), and voluntary registration is available from AED 187,500.

Not every supply carries the 5%: some are zero-rated (exports, certain healthcare and education) and some are exempt (certain financial services, residential leases), which changes how much input VAT a business can recover. Registered businesses file periodic VAT returns to the Federal Tax Authority and pay any net VAT due by the filing deadline the Federal Tax Authority sets for each tax period. You can estimate the VAT on a given invoice with our VAT calculator. The practical point is that a company can be liable for corporate tax, VAT, both or neither, and it must assess each regime on its own thresholds.

Beneficial ownership (UBO) and Economic Substance (ESR)

Two disclosure regimes sit alongside the tax rules and catch most onshore companies. Under Cabinet Decision No. 109 of 2023 on Regulating the Beneficial Owner Procedures (which replaced Cabinet Resolution No. 58 of 2020), companies must identify their Ultimate Beneficial Owner — broadly, the natural person or persons who ultimately own or control the company — file those details with the relevant licensing authority, maintain an internal register of beneficial owners and partners, and keep it up to date as ownership changes.

Economic Substance Regulations under Cabinet Resolution No. 57 of 2020 apply to entities that carry on defined "Relevant Activities" — categories such as banking, insurance, investment fund management, lease-finance, headquarters, shipping, holding company, intellectual property and distribution-and-service-centre business. Those entities must demonstrate real economic substance in the UAE and file notifications and, where applicable, substance reports. The reporting scope was later narrowed: under Cabinet Decision No. 98 of 2024, the Economic Substance Regulations cease to apply to any financial year ending after 31 December 2022, so ESR notifications and reports are generally no longer required for current financial years. Both regimes are documentation-driven: the authority's starting question is always "show me the register" or "show me the report".

Record-keeping, returns and penalties

All of the above rests on documentation. For corporate tax, a taxable person must keep the accounting records and documents behind its return for at least seven years after the end of the tax period. VAT records are generally retained for at least five years, longer for real estate.

Corporate tax returns are filed once per tax period, within nine months of the period's end, with any tax due paid by the same date. VAT, by contrast, is filed periodically through the year. Filing late or getting the numbers wrong exposes a business to administrative penalties under each regime, so most companies reconcile a single clean set of books to both well before either deadline.

How this fits with the Commercial Companies Law

Tax compliance sits on top of your corporate structure, which is itself governed by Federal Decree-Law No. 32 of 2021, the Commercial Companies Law. The way a company is formed — an LLC, a private or public joint stock company, or a branch of a foreign company — shapes who is authorised to sign the tax return, how profits and dividends are distributed, and how ownership is recorded for UBO purposes.

Keeping your memorandum of association, shareholder register and accounting records aligned with your tax filings is not housekeeping; it removes the contradictions that surface during a Federal Tax Authority review. A share transfer that never reached the UBO register, or profit distributions that don't match the accounts, are exactly the mismatches an audit is built to find.

Frequently asked questions

Do I have to register for corporate tax if my profit is under AED 375,000?

Yes. Registration is mandatory for every taxable person, regardless of profit. Even if all of your taxable income falls within the 0% band up to AED 375,000, you must still register with the Federal Tax Authority, obtain a Corporate Tax Registration Number and file a return for each tax period. The 0% rate reduces the tax you pay to zero on that portion — it does not remove the obligation to register and file.

What is the corporate tax rate in the UAE?

The UAE applies two headline corporate tax rates under Federal Decree-Law No. 47 of 2022: 0% on taxable income up to AED 375,000 and 9% on taxable income above AED 375,000. A qualifying free zone person may keep a 0% rate on qualifying income, and very large multinational groups can face a separate minimum top-up tax. Your effective rate depends on your income level, structure and any reliefs claimed.

Are free zone companies exempt from UAE corporate tax?

Not automatically. A free zone company can access the 0% rate only as a Qualifying Free Zone Person, and only on qualifying income, while meeting conditions on substance, transfer pricing and non-qualifying revenue limits. Income that does not qualify, or a breach of the conditions, can be taxed at 9%. Free zone businesses must still register with the Federal Tax Authority and file corporate tax returns like mainland companies.

Is corporate tax the same as VAT in the UAE?

No. Corporate tax and VAT are separate regimes with separate registrations, returns and thresholds. Corporate tax under Federal Decree-Law No. 47 of 2022 is charged on business profits. VAT under Federal Decree-Law No. 8 of 2017 is a 5% tax on most goods and services, with mandatory registration once taxable supplies exceed AED 375,000. A business can be liable for both, one, or neither depending on its activity.

What records do I need to keep for UAE corporate tax?

For corporate tax, you must keep the accounting records and supporting documents behind your return for at least seven years after the end of the relevant tax period. That includes financial statements, invoices, contracts and transfer-pricing documentation where relevant. VAT records are generally kept for at least five years. Reliable bookkeeping that reconciles to both regimes is the practical backbone of staying compliant and surviving a Federal Tax Authority review.

What happens if I register for corporate tax late?

Filing your corporate tax registration after your deadline exposes the business to an administrative penalty set by the authorities. Deadlines were staggered based on when your licence was issued, so the date that applies to you is specific. If you have missed it, register as soon as possible and seek advice on penalty exposure and any voluntary disclosure. Acting quickly generally limits further penalties compared with leaving it unaddressed.
