UAE Corporate Tax Guide: What Every Business Must Know

What Is UAE Corporate Tax?

The UAE had zero corporate tax for a very long time. Then, in June 2023, that changed. Businesses now pay a direct tax on their profits. (Honestly, when it was first announced, a lot of business owners panicked. Then they saw the actual numbers and calmed down pretty quickly.)

Who Needs to Pay UAE Corporate Tax?

Pretty much anyone running a business here. Mainland companies, free zone companies, foreign businesses with a UAE presence, and even individuals doing taxable business activity. A few entities are examples, but that is a small group. If you are open for business in the UAE, assume this applies to you.

UAE Corporate Tax Rates

This is the part most people want to know first.

  • 0% on profits up to AED 375,000

  • 9% on anything above AED 375,000

  • 0% on qualifying free zone income

  • Very large multinationals above 750 million euros in global revenue may face a 15% minimum tax from 2025

For most businesses here, 9% only applies once you are already doing well. The threshold is generous on purpose.

Who Must Register for UAE Corporate Tax?

Everyone, basically. Corporate tax registration in the UAE covers mainland businesses, free zone companies, taxable individuals, and most juridical persons. Some exempt entities still need to register if the FTA asks. Skip the deadline, and you are looking at an AED 10,000 fine before you have even filed anything.

UAE Corporate Tax for Free Zone Companies

Free zone companies are inside the corporate tax system. The 0% rate on qualifying income is still there, but you have to earn it. The business needs proper substance in the free zone, must stick to qualifying activities, and has to file IFRS financial statements. Income that falls outside qualifying activities gets taxed at 9%. (Being in a free zone helps, but it does not automatically protect everything.)

How to Calculate UAE Corporate Tax

Take the accounting profit from the books. Adjust for anything the tax law requires, remove exempt income, apply any deductions available, and tax what is left. It is not complicated in theory. In practice, it comes down to whether the books are clean or messy.

Documents and Records Businesses Should Maintain

  • Financial statements

  • Invoices and expense proof

  • Accounting records

  • Tax registration details

  • Transfer pricing documents if the business deals with related parties

  • Free zone qualifying income records

Keep everything for seven years. The FTA can come back and ask.

UAE Corporate Tax Registration and Filing Process

  1. Check If You Are Taxable

    Look at the business structure, activity type, and whether any exemption applies.

  2. Register on EmaraTax

    Go to the EmaraTax portal, enter business details, and get the corporate tax registration number. Registration deadlines depend on when the trade licence was issued.

  3. Get the Accounts Ready

    Close the books, calculate taxable income, and pull together supporting documents.

  4. File and Pay

    Submit the return by the corporate tax filing deadline and pay whatever is owed.

UAE Corporate Tax Deadlines

The return is due nine months after the tax period ends. For businesses running on a calendar year, the first deadline was 30 September 2025. These dates are worth writing down somewhere visible.

Conclusion

Corporate tax is now part of doing business in the UAE. The rates are low, but ignoring them is not an option. Get registered, keep proper records, and file on time. Not sure where your business stands? Talk to Nexture and get it sorted properly.
