The below are essential:
1) Salary break-up containing amount of Basic, DA (if any) and HRA in both employment contract / appointment letter and pay-slip;
2) Proof of payment of actual rent i.e. Rent receipt etc.
You need not attach any proof, at the filing of return of income. However, you may need to submit proof of payment rent to your employer yearly once / twice as per the policy of your organisation.
