Key Takeaways
- Most Dubai businesses must register for corporate tax via EmaraTax
- Registration deadlines are tied to licence issuance dates
- Late registration attracts administrative penalties
Corporate tax applies across the UAE, and Dubai companies — mainland and free zone alike — must register even if they expect to pay 0%. Getting registration right and on time is the foundation of corporate tax compliance.
Who must register
Taxable persons — including mainland companies, most free zone entities, and certain individuals conducting business — must register for corporate tax. Free zone companies must register too, even where they expect the 0% qualifying rate, because registration is separate from the rate that ultimately applies.
The EmaraTax process and deadlines
Registration is completed through the FTA's EmaraTax portal, which issues a corporate tax registration number. The FTA has set registration deadlines linked to licence issuance dates, so Dubai businesses should check their specific deadline and register promptly to avoid penalties.
After registration
Once registered, a Dubai company must file its corporate tax return within nine months of the end of its financial year and pay any tax due. Maintaining audited, reconciled accounts throughout the year makes that filing accurate and straightforward.
