In this guide, we’ll explore everything you need to know about tax-saving fixed deposits in India—how they work, who should invest, how much you can save, and which banks offer the best interest rates in 2025.
✅ What is a Tax Saving Fixed Deposit?
A Tax Saving Fixed Deposit (FD) is a special type of fixed deposit offered by banks and post offices that comes with a lock-in period of 5 years and provides tax deductions under Section 80C of the Income Tax Act.

📈 How Do Tax Saving FDs Work?
When you invest in a tax-saving FD, your money is locked in for 5 years. You can choose to receive interest either periodically (non-cumulative) or at the end of the tenure (cumulative).
However, the interest earned is fully taxable, and banks deduct TDS (Tax Deducted at Source) if the annual interest exceeds ₹40,000 (₹50,000 for senior citizens).
