What Is a Tax Registration Number in the UAE and How to Get One

Over 350,000 businesses hold an active Federal Tax Authority (FTA) registration in the UAE [1]. Here's what you need to know about a tax registration number in the UAE and how to get one: it's a 15-digit ID, the application fee is AED 0, and late corporate tax registration costs AED 10,000 [1]. This guide is for free zone owners and finance managers.

What Is a Tax Registration Number in the UAE and How to Get One and Why It Matters

A tax registration number (TRN) is a unique 15-digit identifier issued by the FTA when a business registers for VAT or corporate tax. It identifies your company on invoices, returns and FTA records. You get one by registering on the EmaraTax portal with your trade license and ownership documents.

What a TRN Actually Is and What It Looks Like

The TRN is tied to your EmaraTax account and legal entity. VAT and corporate tax can carry separate TRNs. A free zone trading company, for example, prints its VAT TRN on every tax invoice sent to a mainland customer.

VAT TRN vs Corporate Tax TRN at a Glance

Why Free Zone Companies Need One

• Corporate tax registration is mandatory for free zone entities.

• Valid tax invoices, returns and refunds require it.

• Banks ask for it at onboarding. A Dubai South consultancy may need to show its TRN before opening a corporate account.

• Rates: 9% corporate tax above AED 375,000, and 5% VAT since 2018 [2].

TRN Versus Trade License Number

Your free zone authority issues the license number. The FTA issues the TRN. They serve different compliance functions, and new companies often swap them in invoice headers. Read more about what your license number means.

Who Must Register and Key Deadlines for a Tax Registration Number in the UAE

All UAE-incorporated companies, including free zone entities, must register for corporate tax. VAT registration is mandatory once taxable supplies and imports exceed AED 375,000 in 12 months, and voluntary from AED 187,500. Late corporate tax registration triggers a fixed AED 10,000 penalty [1].

Corporate Tax Registration Requirements

• Registration applies from incorporation, even with zero revenue.

• Qualifying Free Zone Persons still register.

• See registering for corporate tax after company formation.

VAT Registration Thresholds

Say a trading firm crosses AED 375,000 in month nine. It must register within 30 days of that point. The standard VAT rate is 5%.

Deadlines and Penalties to Track

• Corporate tax returns fall due nine months after financial year-end [1].

• A December year-end company diarises 30 September.

• Set calendar reminders for each filing date.

How to Get a Tax Registration Number in the UAE Step by Step

To get a TRN, create an EmaraTax account, add your legal entity, choose VAT or corporate tax, upload your documents, submit, and wait for FTA approval. Your TRN appears in your account once approved. Here's how a tax registration number in the UAE and how to get one plays out in practice.

Step 1: Prepare Your Documents

Assemble your trade license, owner IDs and financial year-end in one folder before opening the portal.

Step 2: Create Your EmaraTax Account

Sign up on the official FTA portal with your email and mobile. A UAE Pass login works too. Verify the account, then add your taxable person profile.

Step 3: Complete and Submit the Application

Select corporate tax or VAT, enter entity and ownership details, and match your licensed activity exactly. The fee is AED 0 [1]. Declare and submit.

Step 4: Receive and Store Your TRN

Track status in EmaraTax and download the certificate. Then update your accounting software, bank and accountant. See the corporate tax registration cost breakdown.

Documents and Information Needed for a Tax Registration Number in the UAE

You need a valid trade license, owners' passport and Emirates ID copies, the authorised signatory's details, proof of authority, activity information and a contact address. VAT applications also need turnover figures and customs details for importers.

Core Company and Owner Documents

• Trade license and MOA (Memorandum of Association).

• Passport and Emirates ID copies.

• A notarised authority letter if a manager applies for non-resident owners.

VAT-Specific Information

• Last 12 months' turnover against the AED 375,000 threshold.

• Projected 30-day figures and bank details.

• Customs numbers if you import.

Free Zone Considerations for a Tax Registration Number in the UAE

Free zone companies must register with the FTA even when they expect a 0% rate as Qualifying Free Zone Persons. Registration is federal, so your license doesn't replace it. Non-qualifying income is taxed at 9% [2].

Qualifying Free Zone Person Status

Qualifying income can attract 0%, but only if you meet the conditions in the Corporate Tax Law and ministerial decisions. A Dubai South Business Hub company should register first, then assess each income stream.

Aligning License Activities With Your Application

Your declared activity must match your license. Mismatches trigger FTA queries. If you add an activity, amend your FTA profile promptly.

Common Mistakes and How to Verify Your TRN

Common mistakes include missed deadlines, mismatched activities, expired documents and the wrong signatory. After registration, verify any supplier's TRN with the FTA tool before paying.

Errors That Delay Approval

• Expired Emirates ID or license.

• Names spelled differently across documents.

• An unauthorised signatory.

Verifying a Supplier's TRN Before You Pay

Enter the number in the FTA's online tool and check the name matches the invoice. Keep a screenshot for audit. Our guide on TRN verification in Dubai covers it, and the tax invoice requirements show where your own TRN must appear.

Next Steps for Your TRN

A tax registration number in the UAE and how to get one comes down to accurate documents, an EmaraTax application at AED 0, and meeting FTA deadlines to avoid the AED 10,000 penalty. Gather your license and owner documents, create your EmaraTax account and submit. Contact Dubai South Business Hub to set up your free zone license and residency visa package first.
