Is TDS the full tax on my FD interest?

No. It is an advance payment against a liability calculated at your slab rate when you file. If your slab rate is higher than the deduction rate you will owe more; if it is lower, or you are below the taxable limit, you get a refund.

Can I avoid TDS by splitting deposits across branches?

No. The threshold is assessed per bank across all your deposits, not per branch and not per deposit. Splitting across different banks does reduce it, but the tax liability is unchanged — you simply pay it at filing instead.

Nothing was deducted. Do I still have to declare the interest?

Yes. Interest below the threshold is fully taxable; the bank simply did not withhold anything. It is reported to the department regardless and generally appears prefilled in your return.

How do I get deducted tax back?

File your return. If the amount deducted exceeds your liability the difference is refunded to your bank account. There is no separate application — the return is the claim.

Do senior citizens get a higher threshold?

Yes, senior citizens have a higher exemption threshold for deposit interest before deduction begins, and can use Form 15H rather than 15G to prevent it entirely when their income is below the taxable limit.

TDS on FD interest is a withholding, not a tax bill

The bank deducts at a flat rate against a bill calculated at your slab. It is rarely the right amount, and no deduction does not mean no liability.

The single most common misunderstanding about deposit interest is that TDS is the tax. It is not. TDS is money the bank hands to the government on your behalf, in advance, against a bill that has not been worked out yet. Sometimes it is more than you owe. Sometimes it is less. It is almost never exactly right.

Treating it as a final tax leads to two expensive errors: people who owe nothing never reclaim it, and people in the top slab assume they have paid and get a demand later.

What the bank actually does

When your interest across all deposits at one bank crosses the annual threshold, the bank deducts a percentage of the interest and remits it, then credits you the remainder. It reports the deduction against your PAN, which is how it appears in your annual tax statement and, later, prefilled in your return.

Two details matter and are routinely missed. The threshold is assessed per bank, not per deposit — five deposits at one bank are added together. And it applies to interest accrued in the year, not interest paid, which is why a cumulative deposit that has paid you nothing can still generate a deduction.

Why the amount deducted is rarely the amount owed

Deposit interest is taxed at your slab rate, because it is added to your total income like salary. TDS is deducted at a flat rate that takes no account of your slab, your other income, or your deductions. The two only coincide by accident.

Your situation	What TDS does	What you actually do
Total income below the taxable limit	Deducts anyway, once over the threshold	Reclaim it in your return, or prevent it up front
In a lower slab	Deducts at the flat rate	The difference comes back as a refund
In the top slab	Deducts less than you owe	Pay the balance — budget for it
Interest below the threshold	Deducts nothing	Still declare it and still pay tax on it

That last row is the one that catches honest people out. No deduction does not mean no liability. Interest below the threshold is untaxed at source and fully taxable in your return, and it now arrives prefilled, so omitting it is both wrong and visible.

Work out the tax at your actual slabCompare both regimes, with every deduction that matters.

Stopping the deduction before it happens

If your total income for the year will be below the taxable limit, you can ask the bank not to deduct at all, by submitting a declaration — Form 15G if you are under 60, Form 15H if you are a senior citizen. It is a declaration about your whole year's income, not just the interest at that bank.

1Submit it at the start of the financial year, not after the first deduction. It is not retrospective.
2Submit it separately at every bank where you hold deposits. Banks do not share these.
3Only submit if your total income genuinely falls below the limit — a false declaration is a serious matter, not a form-filling shortcut.
4Re-submit every year. It expires with the financial year.

If you miss the window, nothing is lost — the deduction simply becomes a refund, and you get it back after filing. It is slower, not worse.

How to check what has actually been deducted

Do not rely on the bank's interest certificate alone. The authoritative record is your annual tax statement on the Income Tax Department portal, which shows every deduction reported against your PAN by every deductor. Reconcile the two before you file.

Mismatches are common and almost always mundane — a deposit opened with an old PAN, a joint account reported against the first holder, a branch that filed late. They are also much easier to fix before filing than after.

One structural note: the accrual-versus-receipt mismatch is sharpest on cumulative deposits, where tax can fall due years before any money reaches you. That is covered in cumulative or non-cumulative.
