# House Rent Allowance (HRA) – Section 10(13A)
HRA exemption is available only under the old tax regime. The exempt amount is the least of three figures, with different percentages for metro and non-metro cities.
## The three amounts
### Metro cities (Delhi, Kolkata, Mumbai, Chennai)
Least of:
1. HRA actually received for the relevant period
2. Rent paid − 10% of salary for the relevant period
3. 50% of salary for the relevant period
### Other (non-metro) cities
Least of:
1. HRA actually received for the relevant period
2. Rent paid − 10% of salary for the relevant period
3. 40% of salary for the relevant period
> Only difference between metro and non-metro is 50% vs 40% in the third limb.
## Meaning of 'Salary' for HRA
Salary = Basic Salary + Dearness Allowance (forming part of retirement benefits) + Commission (as a fixed % of turnover).
## Important points
- Computation is done for the relevant period during which the rented accommodation is occupied (compute month-wise if salary, rent, or city changes).
- If the employee lives in own house or pays no rent, the exemption is NIL (limb 2 becomes zero/negative).
