UAE Corporate Tax 2026: Complete Guide for Business Owners

UAE Corporate Tax (CT) came into effect on June 1, 2023. For a country that built its reputation on zero taxation, this was a landmark shift. Yet two years later, the majority of UAE businesses — especially SMEs and free zone companies — are still unclear on what they owe, whether they qualify for relief, and how to stay compliant without overpaying.

This guide covers everything a UAE business owner needs to know about Corporate Tax in 2025.

WHAT IS UAE CORPORATE TAX?

Corporate Tax is a direct tax levied on the net profits of businesses operating in the UAE. It is administered by the Federal Tax Authority (FTA) and governed by Federal Decree-Law No. 47 of 2022.

The tax applies to:
— UAE mainland companies
— Free zone companies (with conditions)
— Foreign companies with a permanent establishment in the UAE
— Individuals conducting business activity in the UAE

The standard rate structure is:

0% — on taxable income up to AED 375,000
9% — on taxable income above AED 375,000
15% — on large multinationals meeting Pillar Two thresholds (revenue above AED 3.15 billion)

For the vast majority of SMEs in the UAE, the relevant rate is 9% on profits above AED 375,000.

WHO IS EXEMPT?

Not every entity pays Corporate Tax. The following are fully exempt:

— UAE federal and emirate governments and their departments
— Wholly government-owned companies (listed in a Cabinet Decision)
— Businesses engaged in the extraction of UAE natural resources
— Qualifying Public Benefit Entities (charities, foundations — if approved by Cabinet)
— Qualifying Investment Funds
— Pension funds and social security funds

Partial exemption — Qualifying Free Zone Persons (QFZP):

Free zone companies can benefit from a 0% rate on Qualifying Income if they meet all of the following:

— Maintain adequate substance in the free zone
— Derive income from Qualifying Activities (as defined by the Ministry of Finance)
— Do not elect to be subject to standard CT
— Comply with transfer pricing rules
— Prepare audited financial statements

The most common qualifying activities include: manufacturing, fund management, ship operations, reinsurance, holding company activity, and certain financing activities between group companies.

If a free zone company has any Non-Qualifying Income — even a small amount from mainland customers — that income is taxed at 9%. The 0% applies only to the qualifying portion.

YOUR CORPORATE TAX FINANCIAL YEAR

CT is assessed on your financial year, not a calendar year.

Most UAE companies use one of these:

— January 1 to December 31
— April 1 to March 31
— June 1 to May 31 (the most common for companies incorporated around CT’s effective date)

Your first tax return covers your first full financial year that began on or after June 1, 2023. If your financial year runs January to December, your first CT return covered January 2024 to December 2024, with a filing deadline of September 30, 2025.

STEP 1 — REGISTER FOR CORPORATE TAX

Every taxable business must register with the FTA for Corporate Tax, even if they expect to owe zero tax.

Go to: EmaraTax portal — emaratax.gov.ae

If you are already registered for VAT, your EmaraTax account already exists. Log in and complete CT registration from your dashboard.

For new registrants:
— Create an EmaraTax account with your Emirates ID or UAE Pass
— Select Corporate Tax Registration
— Enter your trade license details, legal structure, and financial year
— Submit

The FTA issues a Corporate Tax Registration Number (CTRN). Keep this — you need it for all CT filings.

Registration deadlines by entity type:

— Juridical persons incorporated in UAE before March 1, 2024: registration deadline was May 31, 2024
— Juridical persons incorporated after March 1, 2024: must register within 3 months of incorporation
— Natural persons (individuals) with business income: deadline is March 31 of the year following the year their income exceeds AED 1 million

If you missed the registration deadline, register immediately. Late registration attracts an administrative penalty of AED 10,000.

STEP 2 — ASSESS YOUR TAXABLE INCOME

Taxable income starts with your accounting net profit and is then adjusted.

Adjustments that INCREASE taxable income:
— Expenses not incurred for business purposes
— Fines and penalties paid to government bodies
— 50% of entertainment and client hospitality expenses (only 50% is deductible)
— Donations to non-approved entities
— Bribes and illicit payments

Adjustments that DECREASE taxable income:
— Dividends received from UAE subsidiaries (exempt)
— Capital gains from qualifying shareholdings (participation exemption)
— Unrealised gains or losses (if you elect to exclude these)
— Small Business Relief (see below)

The result after these adjustments is your Taxable Income. Apply the 0%/9% rate structure to this figure.

STEP 3 — CHECK SMALL BUSINESS RELIEF ELIGIBILITY

Small Business Relief (SBR) allows eligible businesses to be treated as having zero taxable income for a tax period — even if profits exceed AED 375,000.

Eligibility:
— Revenue must not exceed AED 3 million in the tax period
— Revenue must not have exceeded AED 3 million in any previous tax period from June 2023 onwards
— Must be a UAE resident person (not a free zone person, not a member of a multinational group)

If you qualify, you elect SBR on your tax return. Your CT liability becomes zero for that year.

This relief was designed for genuine small businesses and startups. It is not available to businesses that have artificially separated operations to stay under the AED 3 million threshold — the FTA has anti-fragmentation rules for this.

STEP 4 — PREPARE YOUR FINANCIAL STATEMENTS

UAE Corporate Tax requires financial statements prepared under IFRS (International Financial Reporting Standards) or IFRS for SMEs.

Your financial statements must include:
— Income Statement (Profit & Loss)
— Balance Sheet
— Notes to the accounts
— Supporting schedules for related party transactions

For companies with revenue above AED 50 million or free zone companies claiming 0% QFZP status, financial statements must be audited by a registered UAE auditor.

For companies below AED 50 million, audited statements are not mandatory for CT purposes — but the FTA can request supporting documents at any time. Maintain organized records for a minimum of 7 years.

STEP 5 — PREPARE AND FILE THE TAX RETURN

CT returns are filed on the EmaraTax portal.

Filing deadline: 9 months after the end of your financial year.

Examples:
— Financial year January–December 2024: file by September 30, 2025
— Financial year June 2023–May 2024: file by February 28, 2025

Steps on the portal:
— Log in to EmaraTax
— Select Corporate Tax → Tax Return
— Select your tax period
— Enter your taxable income figures
— Apply any exemptions or reliefs
— Calculate tax due
— Submit

Payment is due on the same date as the return. FTA does not send payment reminders. Missing the deadline results in a penalty of AED 500 per month for the first 12 months, then AED 1,000 per month thereafter.

STEP 6 — TRANSFER PRICING COMPLIANCE

If your business has transactions with related parties — parent company, subsidiaries, sister companies, or associated persons — transfer pricing rules apply.

The arm’s length principle requires that all related party transactions are priced as if they were between independent parties. You must:

— Document all related party transactions
— Prepare a Transfer Pricing disclosure form (filed with the CT return)
— Maintain a Master File and Local File if you meet the thresholds

Thresholds for TP documentation:
— Revenue above AED 200 million: Master File required
— Related party transactions above AED 40 million in a category: Local File required

Most SMEs will only need to complete the disclosure form, not the full TP documentation. But transactions like management fees paid to a foreign parent, or loans between group companies, must be priced at market rates and documented.

PENALTIES TO KNOW

The FTA enforces CT compliance strictly. Key penalties:

— Late registration: AED 10,000 (one-time)
— Late return filing: AED 500/month (first year), AED 1,000/month thereafter
— Late tax payment: 2% of unpaid tax immediately, then 4% monthly after one month
— Failure to maintain records: AED 10,000 first time, AED 50,000 repeat
— Failure to submit audited accounts when required: AED 50,000

There is no amnesty program for CT currently. The FTA began compliance reviews in 2024 and penalties are being enforced.

MOST COMMON MISTAKES UAE BUSINESSES ARE MAKING

Not registering because they think they owe no tax: Registration is mandatory regardless of profit level. Zero-profit businesses must still register and file.

Free zone companies assuming they are automatically exempt: The 0% QFZP rate requires meeting specific conditions. Simply being in a free zone is not enough.

Not separating qualifying and non-qualifying income: A free zone company that invoices a mainland UAE customer has non-qualifying income. That portion is taxed at 9% even if the rest qualifies for 0%.

Treating entertainment as fully deductible: Only 50% of client entertainment, meals, and hospitality expenses are deductible. Many businesses are overclaiming this.

Ignoring transfer pricing on intercompany loans: If your UAE company received a loan from a related party abroad at 0% interest — that arrangement must be documented at arm’s length. The FTA is specifically looking at this.
