Income Tax on 13 Lakh Salary

How ₹13,00,000 is taxed under the new regime

For a salaried taxpayer earning ₹13,00,000 a year, the ₹75,000 standard deduction brings taxable income to ₹12,25,000. Since that's just above the ₹12,00,000 rebate threshold, marginal relief under Section 87A caps the tax at the amount the income exceeds ₹12,00,000, rather than the full slab tax of ₹63,750.

After 4% Health & Education Cess, the final new-regime tax payable is ₹26,000.

The old regime comparison

Under the old regime, the same ₹13,00,000 salary (₹50,000 standard deduction, no other itemized deductions claimed) results in taxable income of ₹12,50,000 and a total tax payable of ₹1,95,000.

The two regimes break even once old-regime deductions (beyond the standard deduction) reach roughly ₹7,37,498 — below that level the new regime wins; above it, the old regime does.

What this means month to month

Spread across twelve months, the new-regime figure of ₹26,000 works out to roughly ₹2,167 a month in tax deducted at source, against ₹16,250 a month under the old regime with only the standard deduction claimed. An employer's TDS calculation should track whichever regime the employee has actually declared for the year — a mismatch between the declared regime and the one actually used at filing time is a common, avoidable reconciliation headache come return season.
