What is a UAE Tax Residency Certificate and how do I get one (the 183-day rule)?

A Tax Residency Certificate is an official FTA document proving you're a UAE tax resident, used mainly to claim double-tax treaty benefits abroad. The main route is physical presence of 183 days or more within a rolling 12-month period (days needn't be consecutive). You'll need an Immigration Entry/Exit report and apply online via the FTA portal. Processing time and fees apply.
