Dubai

Dubai's 0% income tax and 9% corporate tax (from 2023) attract high earners globally, but housing, schooling, and lifestyle costs have surged with demand. A villa in Palm Jumeirah now commands $10,000+/month, and elite international school fees exceed $30,000/year. The city welcomed 17 million tourists in 2024 and continues massive infrastructure investment, yet rent growth (up 20% in 2024 alone) outpaces that of any other city on this list, making it the top gainer in living expenses year-over-year.
