Simple answer is, since its the law. But we are not here for simple answers we are here to give clarity. Here it goes, Unlike UAE VAT (Value Added Tax), The Corporate Tax is a tax on profits, therefore the eligibility for its registration is not dependent on profits or sales. If a business exists, it will either make profits or losses, both cases will have a Corporate Tax implication. If it makes profits, it may pay corporate tax and if it makes losses, the losses can be carried forward to next year to be adjusted against that year’s profits for determining final corporate tax liability. Therefore, mere existence of a business make its eligible for Corporate Tax Registration.
