Why is TDS deducted from your salary?
TDS isn't an extra tax — it's your own income tax, collected a little each month instead of all at once. Here's how it works on salary.
What TDS means
TDS stands for Tax Deducted at Source. Under Section 192 of the Income Tax Act, your employer estimates your tax for the year, deducts roughly one-twelfth of it from each month's salary, and deposits it with the government against your PAN. It's the same income tax you'd otherwise pay yourself — just collected as you earn.
How your employer calculates it
To work out your monthly TDS, payroll typically:
- projects your total annual income from salary;
- applies your chosen tax regime — old or new;
- factors in declarations you submit (rent for HRA, 80C, 80D and similar) if you're on the old regime;
- computes your annual tax, then spreads it across the remaining months.
Why it changes during the year
Your TDS isn't fixed. It can change when you submit (or fail to submit) investment proofs, get a hike or bonus, or switch regime. The most common surprise is a jump in January-March, when employers true-up the tax for anyone who hasn't proven their declared investments.
What if too much is deducted?
If your employer deducts more TDS than your actual tax liability, you don't lose it — you claim it back as a refund when you file your income-tax return. All the TDS deducted shows up in your Form 16, and in Form 26AS / AIS on the income-tax portal.
Reduce TDS legitimately
Declaring eligible investments early, choosing the regime that suits you, and claiming HRA can all lower your TDS. Compare the two regimes with the income tax calculator, or see where the rest of your salary goes.
Frequently asked questions
Is TDS the same as income tax?
TDS is your income tax, collected in advance. Your employer deducts it through the year under Section 192; your final tax liability is settled when you file your income-tax return, where TDS already paid is adjusted.
Can I get a TDS refund?
Yes. If the total TDS deducted is more than your actual tax liability for the year, the excess is refunded after you file your income-tax return (ITR). This is common when you declare investments late or change jobs.
Why did my TDS suddenly increase?
TDS often rises in the last quarter (Jan-Mar) if you haven't submitted investment proofs, or after a salary hike, bonus or change in tax regime. The employer recalculates and spreads the remaining tax over fewer months.
Which form shows my salary TDS?
Your employer issues Form 16 after the financial year. You can also see all TDS against your PAN in Form 26AS and the Annual Information Statement (AIS) on the income-tax portal.
