UAE Corporate Tax is now part of everyday business life, and registration on the Federal Tax Authority's EmaraTax portal is the first compliance step nearly every company has to take. This 2026 guide walks you through who must register, the exact steps on EmaraTax, the deadlines that apply to new and existing entities, and the AED 10,000 late-registration penalty you want to avoid.
One quick note before we start: Xrero (اكسريرو) is the all-in-one UAE and KSA cloud ERP and accounting platform written about here — it is not Xero, the separate global accounting brand. Different company, similar-sounding name.
Takeaway: Almost every UAE taxable person — mainland, free zone (including 0%-taxed Qualifying Free Zone Persons), and qualifying individuals — must register for Corporate Tax on EmaraTax, even if no tax is due. New companies generally have 3 months from incorporation, and missing the deadline carries an AED 10,000 penalty (often waivable if you file your first return within 7 months of your first tax period end).
Who must register for UAE Corporate Tax?
Corporate Tax registration is required for every “taxable person,” which is a broader group than many owners assume:
- Mainland companies (LLCs and other juridical persons).
- Free zone entities — including Qualifying Free Zone Persons that benefit from the 0% rate. The 0% rate does not exempt you from registering.
- Individuals (natural persons) conducting business or business activity — but only if their total business turnover exceeds AED 1,000,000 in a Gregorian calendar year.
The key principle: registration is mandatory even if you expect to owe 0% or no tax. Registering is a separate obligation from paying. If you are unsure whether your free zone status or activity qualifies, confirm with the FTA at tax.gov.ae or a tax adviser before assuming you are exempt.
Before you start: what you'll need
EmaraTax registration is entirely online, but it goes much faster if you gather your documents first. Details must match your trade licence exactly — mismatches are the most common reason applications get sent back.
- A valid trade licence (the key reference document).
- Emirates ID and/or passport for the owners and the authorised signatory.
- Memorandum of Association (MoA) or proof of authorisation for the signatory.
- Entity ownership and business details (activities, address, contact information).
- Contact details and a UAEPass account or email to log in.
Step by step: registering on EmaraTax
Step 1 — Create or log in to your EmaraTax account
Go to the EmaraTax portal at eservices.tax.gov.ae and sign in with UAEPass or your registered email. If you already use EmaraTax for VAT, the same account works — you do not create a separate login.
Step 2 — Select Corporate Tax registration
From your dashboard, add a taxable person (if needed), then choose the Corporate Tax registration option to start a new application.
Step 3 — Enter entity, ownership and business details
Complete the entity type, legal form, ownership structure, and business activities. Everything must match the trade licence precisely — the legal name, licence number, and activity descriptions in particular.
Step 4 — Upload the required documents
Attach the trade licence, Emirates ID/passport of owners and the authorised signatory, the MoA or authorisation document, and contact details. Use clear, legible scans.
Step 5 — Review, declare and submit
Check every field, confirm the declaration, and submit. The FTA typically processes applications within about 20 business days. Once approved, you receive your Corporate Tax Registration Number (a TRN for Corporate Tax).
Deadlines: when you must register
Deadlines depend on whether your entity is new or pre-existing, and on whether you are a company or an individual.
| Who you are | Registration deadline |
|---|---|
| Newly established company (mainland or free zone) | Within 3 months of incorporation, establishment, or recognition. |
| Individual (natural person) over AED 1,000,000 turnover in a calendar year | By 31 March of the following year (e.g. crossed in 2025 → register by 31 Mar 2026). |
| Pre-existing entities (2024 rollout) | The original phased deadlines were tied to the month your licence was issued. If you missed yours, register immediately and check the penalty-waiver condition below. |
Note on the licence-month rule: the tranche of deadlines linked to your trade licence's issuance month applied mainly to entities that already existed during the 2024 rollout. For companies formed in 2026, the operative rule is the 3-months-from-incorporation deadline.
The AED 10,000 late-registration penalty (and the waiver)
The administrative penalty for failing to register for Corporate Tax on time is AED 10,000. The good news: since a decision effective 14 April 2025, the FTA waives this penalty if you file your first Corporate Tax return (or annual declaration for exempt persons) within 7 months of the end of your first tax period — instead of the usual 9 months. So even a late registrant can often avoid the AED 10,000 charge by filing early.
If you are at risk, register now and plan to file that first return well inside the 7-month window. For a deeper look at the waiver mechanics, see our guide on the UAE Corporate Tax penalty waiver and deadlines.
How Xrero keeps your books Corporate-Tax ready
Registration is only step one — you then have to keep books that support an accurate Corporate Tax return. This is where Xrero helps, honestly and without overclaiming:
- Clean, audit-ready records — Xrero keeps your ledgers, invoices, and financial statements organised so your taxable income is straightforward to compute. We describe this as producing FTA-compliant records and FAF export, not as any government accreditation of Xrero itself.
- UAE VAT (5%) handling alongside Corporate Tax, so one system covers both filings.
- Bilingual EN + AR bookkeeping for UAE teams, plus KSA support (ZATCA Phase-2 e-invoicing, Saudi VAT 15%) if you operate across both markets.
- One platform for accounting, invoicing, and reporting at AED 99 per user per month, with a 15-day free trial.
To be fair: Xrero does not file your Corporate Tax return into EmaraTax for you, and it is not a substitute for tax advice. Several mature tools — including Xero (زيرو), which is on the FTA Tax Accounting Software Register — may suit a business that wants a globally established brand. What Xrero gives you is well-organised, Corporate-Tax-ready books in one bilingual system built for the UAE and KSA. Learn more on our Corporate Tax software for the UAE page.

Do I have to register for Corporate Tax even if my company pays 0%?
Yes. Registration is mandatory for taxable persons even when no tax is due — this includes Qualifying Free Zone Persons taxed at 0%. Paying tax and registering are separate obligations.
How long does EmaraTax take to approve a Corporate Tax registration?
The FTA typically processes applications within about 20 business days. Once approved, you receive your Corporate Tax Registration Number. Accurate details matching your trade licence help avoid delays.
What is the penalty for registering late?
The administrative penalty is AED 10,000. However, the FTA waives it if you file your first Corporate Tax return within 7 months of the end of your first tax period (per a decision effective 14 April 2025).
When must a new company register?
Newly established juridical persons (mainland or free zone) must register within 3 months of incorporation, establishment, or recognition. Individuals over AED 1,000,000 turnover register by 31 March of the following year.
Is Corporate Tax registration the same as VAT registration?
No — they are separate registrations with separate thresholds, both done on EmaraTax. UAE VAT (standard rate 5%) is mandatory above AED 375,000 in taxable supplies; Corporate Tax registration applies to taxable persons as described above. You can manage both from the same EmaraTax account.
Does Xrero file my Corporate Tax return for me?
No. Xrero keeps Corporate-Tax-ready, FTA-compliant records and FAF export so your return is easy to prepare, but you file on EmaraTax yourself (or via your accountant). Xrero is not a tax adviser and is not government-accredited.
