If the tax on your total income for the year is nil, you can give the bank Form 15G (or Form 15H if you're 60 or older). Conditions apply, so check before you submit.

Common questions
How is FD interest calculated?
Most banks compound interest every quarter. Maturity = deposit × (1 + rate ÷ 4) to the power of the number of quarters.
How much will ₹5 lakh grow to at 7% for 3 years?
About ₹6,15,720, with about ₹1.16 lakh of interest.
When does the bank deduct TDS on FD interest?
Banks deduct 10% TDS (with your PAN) when the interest they pay or credit to you in a financial year is over ₹50,000, or ₹1 lakh if you're 60 or older. Interest from all your deposits with that bank is added together.
Is FD interest tax-free under any section?
Senior citizens can claim up to ₹50,000 of bank and post office interest under 80TTB in the old regime. A 5-year tax-saver FD's deposit counts for 80C, but its interest is taxable.
Reinvested or quarterly payout?
Reinvested (cumulative) grows faster because interest earns interest. Quarterly payout suits regular income.
