The corporate tax only applies to annual profits of more than AED 375,000 (approx. Euro 95,000), i.e. only profits above this exemption limit have to be taxed accordingly.
At the same time, salaries, office, telephone, etc. etc. can of course be claimed as expenses and accordingly reduce profits and therefore also reduce taxes. This means that if you live in the UAE, you can pay yourself a correspondingly high salary (no income tax) and thus reduce the corporate tax back to 0% in most cases.
In addition, if you have an annual turnover of no more than AED 3 million (approx. EUR 750,000), you can apply for a general exemption from this corporate tax. This general exemption is then valid until a maximum of December 31, 2026 and provided that the annual︀ turnover does not exceed the limit of AED 3 million in any tax period.
