Tax Saving Tips: Best Ways to Reduce Tax Under the Old Tax Regime (FY 2025–26)

As we head towards the last quarter of FY 2025–26, salaried individuals should start reviewing their tax planning strategy carefully. One of the most crucial decisions during this period is selecting between the old tax regime and the new tax regime.
While the new tax regime provides reduced tax rates and tax-free income up to ₹12 lakh, it removes most exemptions and deductions. Due to this limitation, a large number of salaried employees continue to choose the old tax regime, which offers multiple legal avenues to reduce taxable income.
With digital payroll platforms like Zlendo Suite, employees can conveniently manage salary structures, submit investment proofs, and ensure correct tax computation through a unified HR and payroll system.
If you have opted for the old tax regime, the following sections explain the most effective ways to lower your tax liability legally.
Salary-Based Tax Exemptions
Under the old tax regime, certain components of salary are either exempt or deductible, helping reduce overall taxable income.
Standard Deduction (Section 16)
All salaried individuals and pensioners are eligible for a standard deduction of ₹50,000, which is automatically reduced from taxable salary income.
House Rent Allowance – HRA (Section 10(13A))
For employees living in rented accommodation, HRA exemption is calculated as the lowest of the following:
