Tax Deducted at Source (TDS) on salary is the most common tax deduction for Indian employees. Your employer acts as a tax collector — deducting tax monthly from your salary and depositing it with the government. But the system has nuances that many employees miss.
How TDS on Salary Works
Under Section 192 of the Income Tax Act, every employer must:
- Estimate the employee's total income for the financial year (April to March)
- Deduct applicable deductions and exemptions declared by the employee
- Calculate the total tax liability on projected income
- Divide the tax by 12 months (or remaining months in the year)
- Deduct that amount monthly from salary
The key word is estimate — if your declared investments don't match actual investments at year-end, you'll either owe more tax or receive a refund.
Form 12BB: The Investment Declaration
Form 12BB is the employee's declaration submitted to the employer at the beginning of the financial year. It informs the employer of:
- House Rent Allowance (HRA) claim — rent paid, landlord details
- LTA (Leave Travel Allowance) claim
- Section 80C investments — PPF, ELSS, home loan principal, LIC, tuition fees
- Section 80D — health insurance premiums
- Home loan interest (Section 24b)
- Any other Chapter VI-A deductions
Form 12BB is a declaration, not a proof. You will need to submit actual proof (rent receipts, premium receipts, bank statements) to your employer before March 31. Failure to submit proof means the employer cannot consider those deductions, resulting in excess TDS.
Timeline:
| Action | When |
|---|---|
| Submit Form 12BB (declaration) | April–May (start of FY) |
| Submit investment proofs | January–March |
| Employer recalculates TDS | February–March |
| Form 16 issued | By June 15 |
HRA Exemption: The Most Frequently Missed Saving
If you live in a rented house and receive HRA as part of your salary, you can claim exemption under Section 10(13A). The exemption is the least of:
- Actual HRA received from employer
- Rent paid minus 10% of Basic + DA
- 50% of Basic salary (metro cities) / 40% (non-metro)
Example: Basic ₹50,000/month | HRA ₹20,000 | Metro rent ₹18,000
- Actual HRA: ₹20,000
- Rent – 10% of basic: ₹18,000 – ₹5,000 = ₹13,000
- 50% of basic: ₹25,000
HRA exempt = ₹13,000/month (least of the three)
If rent to a single landlord exceeds ₹1 lakh per year, you must provide the landlord's PAN to your employer. Non-disclosure means employer cannot grant HRA exemption.
Choosing the Right Regime for TDS
Since the new tax regime is now the default, your employer will automatically apply it unless you specifically opt for the old regime. Submit a declaration (in writing or via Form 12B) to your employer before April if you want to use the old regime for TDS calculation.
Note: Even if TDS is deducted under old regime, you can switch to the new regime at the time of ITR filing (for salaried employees).
Form 16: Your Annual TDS Certificate
Form 16 is the certificate issued by your employer summarising salary paid and TDS deducted during the financial year. It has two parts:
- Part A — Certificate of tax deducted (from TRACES portal, employer-signed)
- Part B — Salary breakup, deductions considered, taxable income computed
Form 16 is the primary document for:
- Filing your ITR (ITR-1 or ITR-2)
- Loan applications
- Visa applications requiring income proof
Employer deadline: Form 16 must be issued by June 15 of the assessment year.
Common TDS on Salary Problems
Problem 1: Excess TDS in February-March
If you forget to submit proofs, your employer applies TDS on full salary without deductions in Jan-Feb-Mar quarter. This means you pay excess tax and have to wait for ITR refund.
Fix: Submit proofs by December. Always follow up with HR.
Problem 2: Multiple Employers in Same Year
If you changed jobs, each employer deducts TDS independently without knowing about the other. You may face tax shortfall at filing.
Fix: Submit Form 12B to your new employer with income and TDS details from previous employer. They will account for it in their calculation.
Problem 3: Freelance / Side Income Not Accounted
Salary TDS does not cover freelance or rental income. If you have additional income, you need advance tax payments.
Form 24Q: The Employer's TDS Return
Your employer files Form 24Q quarterly (return of TDS deductions). This feeds into your Form 26AS and AIS. Any mismatch between Form 16 and Form 26AS should be flagged immediately — it can lead to notices from the Income Tax department.
TDS on Advance Salary, Arrears, and Perquisites
- Advance salary: TDS must be deducted in the year of payment, not the year it relates to
- Arrears: TDS deducted in the year of payment; relief under Section 89 can reduce impact
- Perquisites (car, accommodation, ESOPs): Valued as per Income Tax Rules and included in taxable salary
Your employer's TDS process may have gaps.
