When it comes to interest rate, Post Office Savings Account offers a fixed 4.0% annual interest set by the Central Government. On the other hand, most of the major government and large private banks (like SBI, HDFC, ICICI, PNB) offer only 2.70% to 3.00% annual interest on general savings accounts for balance between ₹1 lakh to ₹10 lakh. Although some select private banks or small finance banks offer slab-based interest ranging from 4% to 6% on large balances, Post Office’s 4.0% interest rate even today ensures higher returns by about 1% to 1.30% compared to traditional and safe large banks.

But Post Office Savings Account comes with an additional special exemption under Section 10(15)(i) of the Income Tax Act. According to this, up to ₹ 3,500 on interest on single post office savings account and up to ₹ 7,000 on interest on joint account are already completely tax-free. After this, simple exemption of ₹ 10,000 can be claimed under Section 80TTA on the remaining interest income.

Most financial experts recommend keeping a bank account for everyday expenses and liquidity, while keeping a portion of your emergency savings in a post office account to earn more interest.
