Hi
1. If you have income below 5 lacs, effective exemption limit becomes 5 lacs by way of rebate for income tax on income between 2.5 to 5 lacs. For those having income above 5 lacs, basic exemption limit is 2.5 lacs only.
2. The insurance limit is applicable on per bank per individual. So if you have 2 bank accounts in same bank, it would be 5 lacs. However, if 2 accounts are with 2 different banks, it would be 10 lacs- 5 lacs each bank.
