How HRA Exemption is Calculated
The Income Tax Act specifies that your HRA exemption is the minimum of three conditions: (1) Actual HRA received from employer, (2) 50% of Basic Salary if you live in a metro city (Mumbai, Delhi, Kolkata, Chennai) or 40% for non-metro cities, and (3) Actual rent paid minus 10% of Basic Salary. The exemption is whichever of these three figures is lowest. This three-way minimum exists to prevent abuse — you cannot claim more than you actually received as HRA, more than a city-adjusted salary proportion, or more than your actual rent outgo.
