UAE Tax Guide

How to Register for UAE Corporate Tax: A Step-by-Step Guide for SMEs

The UAE introduced federal Corporate Tax under Federal Decree-Law No. 47 of 2022. Every taxable person — whether Mainland, Free Zone, or a natural person carrying on a business — must register on the FTA's EmaraTax portal and obtain a Corporate Tax Registration Number (TRN), even if the eventual tax liability is 0%. This guide walks SME owners and finance teams through the full registration process.

What you'll learn

  • Who needs to register (and when)
  • Documents to gather before you start
  • Step-by-step EmaraTax portal walk-through
  • Registration deadlines and penalties
  • Common mistakes SMEs make

1. Who must register for UAE Corporate Tax?

Corporate Tax applies to almost every business that operates in the UAE. Registration is a separate, mandatory step from filing — you must register even if your taxable income is below the AED 375,000 threshold or you qualify for the 0% Free Zone rate.

  • Mainland companies — LLCs, sole establishments, and civil companies holding a UAE trade licence.
  • Free Zone Persons — including Qualifying Free Zone Persons (QFZP) taxed at 0% on qualifying income.
  • Branches of foreign companies operating in the UAE.
  • Natural persons conducting business with turnover above AED 1 million per calendar year.
  • Non-resident persons with a UAE permanent establishment or UAE-sourced income.

2. Documents you need before you start

Gather these before opening the EmaraTax portal — the application times out if left idle and cannot be partially saved in certain steps.

Trade licence

Valid trade licence (Mainland or Free Zone), including all activity codes.

Emirates ID & passport

Copies for every owner, partner, and authorised signatory.

MoA / AoA

Memorandum & Articles of Association, or partnership agreement.

Contact details

Registered address, PO Box, business email, and mobile number.

Financial year

Confirm your accounting period (most SMEs use 1 Jan – 31 Dec).

Power of Attorney

If a tax agent or consultant submits on your behalf.

3. Step-by-step: registering on EmaraTax

  1. 1

    Log in to EmaraTax

    Go to eservices.tax.gov.ae and sign in with UAE Pass or your existing FTA credentials. First-time users create an account with a UAE mobile number.

  2. 2

    Create or select your Taxable Person profile

    From the dashboard, add a Taxable Person for your entity (or natural person). Each legal entity needs its own profile — one login can manage many.

  3. 3

    Start the Corporate Tax registration

    Inside the Taxable Person, choose Corporate Tax and click Register. Read the acknowledgements and continue.

  4. 4

    Entity details

    Select your entity type (LLC, Free Zone, branch, natural person, etc.), enter trade licence number, issue and expiry dates, and business activities.

  5. 5

    Identification details

    Add owners, partners, and authorised signatories with Emirates ID and passport data. Upload each document as a legible PDF/JPG.

  6. 6

    Contact & address

    Enter registered address, PO Box, primary business email, and mobile number. The FTA sends notifications here — use an inbox you monitor.

  7. 7

    Review, sign, and submit

    Review the summary, tick the declarations, and submit. You will receive an application reference number and a status update via email — typically within 20 business days.

4. Registration deadlines

FTA Decision No. 3 of 2024

Deadlines depend on the month your trade licence was issued (year is ignored). Most existing UAE companies were required to register within 3–10 months of the effective date. New businesses incorporated on or after 1 March 2024 must register within 3 months of incorporation. Natural persons crossing AED 1 million turnover must register by 31 March of the following year.

Late-registration penalty

Cabinet Decision No. 75 of 2023 sets an AED 10,000 administrative penalty for failing to register for Corporate Tax within the required timeline.

5. Common mistakes to avoid

  • Registering with an expired trade licence — renew first.
  • Using an owner's personal email — use a business inbox you actively monitor.
  • Free Zone entities assuming they don't need to register — QFZPs still must register.
  • Uploading blurry Emirates ID scans — the FTA will reject the application.
  • Missing the deadline by a few days — the AED 10,000 penalty applies from day one.
