How the calculation works

  1. Gross income = salary + other income.
  2. Standard deduction: ₹75,000 (new) or ₹50,000 (old). Old regime also subtracts HRA, 80C (cap ₹1.5 lakh), 80CCD(1B) (cap ₹50,000), 80D, 24(b) (cap ₹2 lakh), 80E and 80G.
  3. Slab tax on taxable income, then the Section 87A rebate if taxable income is within the limit (₹12 lakh new, ₹5 lakh old).
  4. Surcharge above ₹50 lakh with marginal relief, then 4% cess on tax plus surcharge.
  5. Monthly TDS is the annual tax divided by twelve; an employer spreads it across the remaining months of the year.

For employers: TDS on salary

Section 192 requires the employer to estimate each employee's annual tax at the start of the year, using the regime the employee declares, and deduct it monthly. A wrong estimate is corrected in the last quarter, which is why March payslips often carry a larger TDS line. Payroll software that stores the declaration and recomputes TDS each month removes that year-end jump.
