For onshore limited liability companies in the UAE in free trade zones the minimum threshold for share capital is from 0 up to 150 thousand dirhams, and in some instances it may be more.
For establishment of onshore company in Dubai or any other Emirate outside FTZ the minimum threshold of the share capital may reach 300 thousand AED, at the same time for this type of companies, as a rule, it is not necessary to pay it for most activities. However, for this type of companies, under certain types of activities, it is necessary to provide a bank guarantee of a certain value. For example, for tourism companies it is necessary to provide a guarantee in the value of AED 100.000 - for inbound license, and a similar amount - for outbound license.
For offshore companies in Dubai and Ras Al Khaimah paying share capital is not required by definition.
For a public company, the minimum threshold of the share capital may reach 10 million dirhams, while a quarter of the amount shall be paid at the time of registration.
Summing up the above - depending on the place of registration of the company in the UAE (in free trade zone or outside it) as well as the type of company and its license, restrictions and requirements for the share capital of the company may differ significantly.
