Every business operating in Ajman is now required to register for Corporate Tax under the UAE Federal Tax Authority (FTA). Whether you run a mainland company, a free zone entity, or a branch office, completing your Corporate Tax registration is a legal obligation, not a choice. At ADS Auditors, we make this process seamless, accurate, and fully compliant with the latest FTA requirements in 2026.
What Is Corporate Tax Registration?
Corporate Tax registration is the formal process through which a taxable person or business entity registers with the FTA on the EmaraTax portal to obtain a Corporate Tax Registration Number (CT TRN). This unique number is your business's identity for all corporate tax compliance purposes in the UAE.
Under Federal Decree-Law No. 47 of 2022, all juridical persons incorporated in the UAE, including those in Ajman, are required to register for Corporate Tax. This applies regardless of whether the business is currently profitable.
Who Needs to Register for Corporate Tax in Ajman?
The following categories of businesses and individuals operating in Ajman are required to register:
Juridical Persons (Legal Entities):
- Limited Liability Companies (LLCs) registered in Ajman
- Public and Private Joint Stock Companies
- Entities formed under Ajman Free Zone (AFZ) or Ajman Media City Free Zone
- Foreign companies with a permanent establishment or taxable nexus in the UAE
Natural Persons (Individuals): A natural person conducting business in Ajman must register for Corporate Tax if their total annual revenue from business activities exceeds AED 1,000,000 within a calendar year. Note: salary income, private investment returns, and real estate investment income are excluded from this calculation.
Important: UAE branches of a domestic juridical person are considered extensions of their parent company and do not register separately.
Why Corporate Tax Registration in Ajman Cannot Be Delayed?
Missing your Corporate Tax registration deadline attracts administrative penalties from the FTA. More critically, failure to register prevents you from filing tax returns, which means you cannot carry forward tax losses to offset future taxable income. Timely registration protects your business from penalties and ensures your financial records remain FTA-compliant.
Corporate Tax Rates Applicable to Ajman Businesses (2026)
| Taxable Income | Tax Rate |
| Up to AED 375,000 | 0% |
| Above AED 375,000 | 9% |
| Qualifying Free Zone Persons (on qualifying income) | 0% |
Even businesses that fall within the 0% bracket must still register and file returns.
