Payroll
How salary TDS works
Employers estimate annual taxable salary and deduct tax from monthly salary during the year.
The estimate can change when you submit declarations, investment proofs, rent details, previous employer income, or regime choices.
- Annual salary projection
- Regime selection
- Deductions and exemptions
- Monthly deduction
- Year-end adjustment
Example
Monthly deduction flow
- Annual tax estimate is prepared.
- Tax is spread across remaining months.
- Payroll adjusts if declarations change.
Monthly TDS can vary
TDS is often higher in later months if proof submission changes the employer estimate.
Inputs
Declarations and proof submission
Payroll often asks for declarations early in the year and proofs later. These influence the salary TDS estimate.
If proof is not submitted on time, payroll may ignore the deduction for TDS calculation, even if you can still review eligibility while filing.
- HRA rent details
- 80C investments
- 80D insurance
- NPS
- Previous employer income
Example
Missed declaration example
- You planned 80C investment.
- Proof was not submitted to payroll.
- Employer deducts higher TDS near year-end.
Filing can still matter
Some eligible deductions may still be claimed while filing, depending on regime and rules, even if payroll missed them.
Adjustment
Why TDS changes near year-end
Salary TDS can rise in the last quarter because employers finalize proofs, bonuses, arrears, and previous employer details.
This is normal, but a large unexpected change should be checked against payroll computation.
- Bonus
- Arrears
- Proof rejection
- Previous employer salary
- Regime update
Example
March adjustment
- Bonus is paid in March.
- Taxable salary increases.
- March TDS becomes higher than usual.
Check before filing
Use Form 16 and the TDS calculator to estimate whether final TDS is reasonable.
