1. What is TDS on salary?
Tax Deducted at Source (TDS) on salary is the mechanism by which your employer deducts income tax from your monthly salary and deposits it with the government on your behalf. It's a "pay as you earn" system — tax is collected throughout the year rather than as a lump sum at the end.
Your employer estimates your annual taxable income based on the declarations you submit (investments, rent, etc.) and deducts tax accordingly. If your actual liability at year-end differs, you settle it via your Income Tax Return (ITR).
2. How is TDS calculated?
The calculation follows a simple sequence:
- Estimate gross annual salary
- Subtract exemptions (HRA, LTA, etc.) — old regime only
- Subtract standard deduction (₹50,000)
- Subtract Chapter VI-A deductions (80C, 80D, etc.) — old regime only
- Arrive at net taxable income
- Apply slab rates
- Add health & education cess (4%)
- Subtract rebate (if applicable)
- Divide by 12 for monthly TDS
💡 TDS is an estimate. If you forget to declare an investment, your TDS will be higher than necessary. You can claim the excess back when filing your ITR.
3. Old vs new tax regime
| Feature | Old regime | New regime |
|---|---|---|
| Standard deduction | ₹50,000 | ₹50,000 |
| 80C (₹1.5L) | Allowed | Not allowed |
| 80D (health insurance) | Allowed | Not allowed |
| HRA exemption | Allowed | Not allowed |
| Home loan interest | Allowed (₹2L) | Not allowed |
| Slab rates | Higher | Lower |
The new regime is simpler and has lower rates, but disallows most deductions. If you claim significant deductions (80C + HRA + home loan), the old regime may still be better. Run the numbers both ways.
4. HRA exemption explained
HRA exemption is available only under the old regime. The exempt amount is the least of:
- Actual HRA received
- Rent paid minus 10% of basic salary
- 50% of basic salary (metro) or 40% (non-metro)
For example, if your basic is ₹50,000/month, HRA received is ₹20,000/month, and rent paid is ₹25,000/month in a metro:
- Actual HRA: ₹2,40,000/year
- Rent − 10% of basic: (₹3,00,000 − ₹60,000) = ₹2,40,000
- 50% of basic: ₹3,00,000
- Least = ₹2,40,000 (exempt)
5. Standard deduction
A flat ₹50,000 deduction is available in both regimes. This is automatically applied by your employer when computing TDS. No proof or declaration is needed.
6. How to reduce TDS
- Submit investment proofs on time: Declare 80C, 80D, and HRA at the start of the year so TDS is lower from month one.
- Max out 80C: ₹1.5L across EPF, PPF, ELSS, life insurance, etc.
- Claim 80D: Health insurance premiums up to ₹25k (self) + ₹25k (parents).
- Use NPS 80CCD(1B): Additional ₹50k deduction.
- Home loan interest: Up to ₹2L deduction under Section 24(b).
- Choose the right regime: Compare old vs new every year.
⚠️ Don't over-declare investments you haven't actually made. If your employer deducts less TDS based on false declarations, you'll face a tax demand and possible penalties when filing your return.
7. Common mistakes
- Not submitting proofs: Leads to higher TDS and a refund wait at year-end.
- Forgetting other income: Interest, rent, or freelance income must be reported. TDS may not cover it.
- Ignoring regime choice: Many taxpayers default to old regime without comparing.
- Not updating employer: If you change jobs mid-year, declare previous income to avoid under-deduction.
- Overlooking cess: 4% health & education cess applies on tax.
8. TDS on other income
| Income type | TDS rate | Threshold |
|---|---|---|
| Salary | Slab rates | Basic exemption |
| Interest (FD) | 10% | ₹40,000 |
| Interest (savings) | — | ₹40,000 (no TDS) |
| Rent | 10% | ₹2.4L/year |
| Professional fees | 10% | ₹30,000 |
| Dividends | 10% | ₹5,000 |
TDS on salary is only one part. If you have other income, the corresponding TDS applies separately. Reconcile everything in your ITR.
9. Filing your ITR
Your employer issues Form 16 (TDS certificate) by June 15 after the financial year ends. Use it to file your ITR. If excess TDS was deducted (e.g., you forgot to declare investments), claim a refund. If less was deducted, pay the balance.
10. Final thoughts
TDS is not a tax on its own — it's a prepayment. The goal is to get your monthly deduction as close to your actual liability as possible, so you don't give the government an interest-free loan. Declare investments early, choose the right regime, and reconcile at year-end.
