Income Tax / TDS estimator

Salary TDS is your employer's estimate of your annual liability, spread across twelve months. Getting the declaration right early avoids a painful correction in February and March.

How it is calculated

1

Start from gross salary and remove exempt allowances where the regime permits.

2

Apply the standard deduction available to salaried taxpayers.

3

Deduct eligible investments and payments — only under the old regime.

4

Apply the slab rates for the chosen regime, add cess, then divide across the remaining months.

Worked example

Employers typically recompute TDS every month as declarations and actual payments change, which is why the deduction is rarely identical across all twelve months.

What to watch for

Frequently asked questions

Why did my TDS jump in the last quarter?

Almost always because declared investments were not backed by proofs, so the employer reversed them and recovered the shortfall across the remaining months.

Can I change regime mid-year?

Your employer may allow one change during the year for TDS purposes. The final choice is made when you file your return, subject to the rules for business income.
