United Arab Emirates TIN number guide
Local ED License Number
The United Arab Emirates (UAE) uses a system of licensing for businesses. Businesses typically need to obtain a trade license or commercial license from the relevant authorities, which may vary depending on the location and type of business activity. Each emirate and free zone may have its own set of rules and regulations regarding business licensing.
Tax Registration Number (TRN)
The Tax Registration Number (TRN) is a unique identifier assigned to businesses that are registered for Value Added Tax (VAT) in the UAE. It is a 15-digit number, with the first 12 digits being unique to each business, and the last three digits representing the branch number if applicable. The TRN can be verified online through the official portal of the Federal Tax Authority (FTA) in the UAE.

Frequently Asked Questions
Does a non-resident foreign company selling digital services into the UAE need to register for a TRN?
Yes — and unlike most VAT regimes, there is no minimum revenue threshold for non-residents. Under Federal Decree-Law No. 8 of 2017, a non-resident business that makes any taxable supplies in the UAE must register with the Federal Tax Authority (FTA) and obtain a TRN immediately, unless a UAE-registered recipient will self-account for the VAT under the reverse-charge mechanism. For B2C digital services — software subscriptions, streaming, SaaS — the reverse charge is not available, so foreign providers must register, collect 5% VAT, and file returns directly with the FTA.

Will a UAE free zone company automatically pay 0% Corporate Tax on all its income?
No — the 0% rate applies only to "Qualifying Income" earned by a "Qualifying Free Zone Person" (QFZP), and that status is not automatic. Under Federal Decree-Law No. 47 of 2022, a free zone entity must maintain real substance (assets, qualified employees, core activities performed in the zone), keep audited financial statements, and comply with transfer-pricing rules. Critically, if non-qualifying revenues exceed the lower of 5% of total revenue or AED 5 million in any tax period, the entity loses QFZP status for that year and the next four years, and all income becomes taxable at 9%. Revenue from mainland UAE clients, most financial services, and intellectual property exploited outside qualifying activities is excluded from the 0% treatment. [3] [4]
Can a business with revenue under AED 3 million avoid paying UAE Corporate Tax entirely?
A UAE-resident business may elect Small Business Relief (SBR) and be treated as having zero taxable income for any tax period in which its revenue does not exceed AED 3 million. The relief is available for tax periods starting on or after 1 June 2023 through periods ending on or before 31 December 2026. However, two categories are categorically excluded: Qualifying Free Zone Persons (who have their own 0% regime) and members of a Multinational Enterprise Group. If revenue exceeds AED 3 million even once, the business is ineligible for SBR from that period onwards and must file a full Corporate Tax return. [5] [6]
What is the penalty for issuing a VAT invoice that omits the supplier's TRN?
A tax invoice that does not include the supplier's TRN fails the mandatory content requirements of Article 59 of the VAT Executive Regulations. Under Cabinet Decision No. 49 of 2021, the administrative penalty for failing to issue a compliant tax invoice is AED 1,000 for a first offence and AED 2,000 for each repeated violation — a reduction from the original AED 5,000 flat penalty set by Cabinet Decision No. 40 of 2017. The practical consequence for the buyer is equally serious: without a supplier TRN on a full tax invoice, the buyer cannot recover the input VAT on that purchase, effectively turning the 5% VAT into an irrecoverable cost. [7] [8]
When does the UAE e-invoicing mandate apply, and does it affect businesses that only have a TRN and not a Corporate Tax registration?
The UAE mandatory e-invoicing system rolls out in two waves for B2B and B2G transactions. Businesses with annual revenue of AED 50 million or more must appoint an Accredited Service Provider (ASP) by 31 July 2026 and go live by 1 January 2027; all other businesses in scope must be live by 1 July 2027. Crucially, the mandate covers businesses regardless of their VAT registration status — any entity conducting business in the UAE must register with the FTA to obtain a Tax Identification Number (TIN), which is the first 10 digits of its TRN or Corporate Tax registration number. Businesses not otherwise required to register for Corporate Tax must still register with the FTA specifically to obtain this TIN before transmitting e-invoices. [9] [10]
