When is the deadline to register for corporate tax in the UAE?

There is no single universal corporate tax registration date in the UAE — the Federal Tax Authority (FTA) has set staggered deadlines based on factors such as when your trade licence was issued, and separate timelines apply to natural persons carrying on a business and to non-resident persons. The FTA published these deadlines in a decision specifically to schedule registration in waves, and registering after your applicable deadline can result in an administrative penalty. Because the deadline that applies to you depends on your specific licence and entity type, you should check your exact date directly through the FTA's EmaraTax portal or the FTA's published registration-timeline decision rather than relying on a general figure. Even businesses expecting a 0% effective rate, including many free zone companies, generally still have to register by their deadline. If you are unsure which wave applies to you or have already missed a date, act quickly, as penalties can accrue.
