Many salaried employees are often surprised to notice a drop in their take-home salary in April despite receiving no salary hike or compensation revision. In most cases, the reason is linked to changes in Tax Deducted at Source (TDS) calculations at the start of the new financial year.
The shift usually happens because employers begin recalculating annual tax liabilities from April onward, leading to revised monthly deductions.
Why TDS Often Rises at the Start of the Financial Year
April marks the beginning of a new financial year in India, and companies typically reset payroll and tax calculations during this period.
Employers estimate an employee’s projected annual income and divide the expected tax liability across the remaining months of the financial year. This often results in higher monthly deductions initially, especially if tax-saving declarations or exemptions have not yet been submitted.
Common reasons for increased April tax deductions include:
- Fresh annual tax calculations by employers
- Non-submission of investment declarations
- Revised salary structures or bonuses
- Previous under-deduction adjustments
- Job changes during the earlier financial year
Why Job Switchers Notice Bigger TDS Changes
Employees who switched jobs during the previous financial year are more likely to experience a sharp increase in April deductions.
When a person joins a company midway through the year, the employer may initially calculate taxes based only on income earned after joining. This can sometimes result in lower TDS deductions during the remaining months of that financial year.
However, from April onward, the employer calculates taxes assuming a full 12-month salary cycle, which can significantly increase monthly deductions even if salary remains unchanged.
Investment Declarations Play a Major Role
Many companies ask employees to submit tax-saving investment declarations at the beginning of the financial year.
If employees delay or fail to declare investments under sections such as:
- Section 80C
- Health insurance deductions
- Home loan interest benefits
- NPS contributions
- HRA exemptions
the payroll system may temporarily calculate taxes without considering these deductions, resulting in higher TDS.
Once investment proofs or declarations are updated, deductions may normalize in later months.
Bonuses and Variable Pay Can Also Impact TDS
Annual bonuses, incentives, retention payouts, or variable compensation received near the financial year-end can affect future TDS calculations.
Employers often annualize projected income while estimating tax liability, which may temporarily push employees into higher tax brackets for monthly deduction purposes.
This does not necessarily mean overall tax liability has permanently increased, but monthly deduction distribution may change.
New vs Old Tax Regime Impact
Another reason employees may notice deduction changes is due to tax regime selection.
At the beginning of the financial year, payroll departments may reset employees into a default tax regime unless declarations are submitted. The difference between the old and new tax regimes can alter monthly TDS calculations substantially.
Employees should carefully review:
- Tax regime selection
- Declared deductions
- Salary breakup
- Exemptions and reimbursements
- Previous employer income disclosures
How Employees Can Reduce Unexpected TDS Deductions
To avoid sudden tax shocks in April, salaried individuals should:
- Submit investment declarations early
- Share previous employer income details accurately
- Review salary structure carefully
- Verify tax regime selection
- Plan tax-saving investments in advance
Maintaining updated payroll records can help employers calculate more accurate monthly deductions throughout the year.
Conclusion
Higher TDS deductions in April are usually part of routine annual payroll adjustments rather than a reduction in salary. Understanding how employers calculate taxes, especially after job switches or incomplete declarations, can help employees better manage cash flow and avoid surprises in monthly take-home pay.
