How fixed deposit interest is taxed (and TDS explained)

The return you see isn't the return you keep A fixed deposit's headline rate is reassuringly certain — but the interest it earns is fully taxable, and that quietly lowers your real return. Understanding how helps you avoid surprises at tax time.

Interest is taxed at your slab rate FD interest is added to your total income and taxed at whatever income-tax slab you fall into. So a 7% FD is really earning you closer to 4.9% after tax if you're in the 30% bracket. The higher your income, the more the taxman trims the return.

It's taxed every year, even before payout A key surprise: interest is generally taxable as it accrues each year, not only when the FD matures. On a multi-year cumulative FD, you may owe tax on interest you haven't yet received in hand. Reporting it yearly avoids a large bill at maturity.

What TDS is Banks deduct TDS (Tax Deducted at Source) — an advance slice of tax — once your interest from that bank crosses a yearly threshold. Points to know: - TDS is not an extra tax; it's adjusted against your total tax liability when you file. - If your total income is below the taxable limit, you can submit Form 15G/15H to ask the bank not to deduct TDS. - If your slab is higher than the TDS rate, you'll still owe the difference when you file.

Planning around it - Spread deposits across people or the financial year to manage when interest lands. - Factor tax into comparisons. After tax, an FD's edge over an equity SIP narrows further, since long-term equity gains are usually taxed more gently. - Keep records of interest certificates so your return matches the bank's.

Use the FD calculator to see the pre-tax maturity value, then apply your slab rate to estimate what you'll actually keep.
