How much income tax on a ₹13 lakh salary?

Income tax on a ₹13 lakh salary is ₹26,000 under the new regime in FY 2026-27, about ₹2,167 a month in TDS. The old regime charges ₹1,95,000 with nothing claimed beyond its ₹50,000 standard deduction, and costs no more than the new regime only once other deductions reach ₹6,88,000.

New regime on ₹13 lakh, slab by slab

Start from ₹13,00,000 of gross salary and take off the ₹75,000 standard deduction: taxable income is ₹12,25,000. The FY 2026-27 new-regime slabs then produce ₹63,750 of slab tax, step by step in the table.

Taxable income is ₹25,000 above the ₹12,00,000 rebate line, and marginal relief caps the tax before cess at that excess instead of the full ₹63,750. With ₹1,000 of 4% cess the total is ₹26,000, about ₹2,167 a month.

Old regime on ₹13 lakh, nothing claimed

The old regime’s standard deduction is ₹50,000, so with nothing else claimed taxable income is ₹12,50,000, and its four slabs produce ₹1,87,500 of slab tax.

Taxable income is above the old regime’s ₹5,00,000 rebate limit, so no rebate applies. With ₹7,500 of cess the total is ₹1,95,000, which is ₹1,69,000 more than the new regime’s ₹26,000 on the same salary.

Deductions the old regime needs to draw level at ₹13 lakh

For the old regime to cost no more than the new regime’s ₹26,000, its deductions beyond the standard deduction must total ₹6,88,000 (rounded up to the next ₹1,000). At that level old-regime tax is ₹25,896. Every old-regime deduction comes off income before the slabs, so it is the total that counts, not which sections it comes from.

That is more than ₹1,50,000 of 80C, ₹25,000 of 80D and ₹2,00,000 of home-loan interest put together (₹3,75,000); the remaining ₹3,13,000 would have to come from other deductions such as HRA exemption. Whether you have that much to claim is yours to check — the table shows the old-regime tax with each section at its limit.

Monthly TDS on a ₹13 lakh salary

Spread evenly over twelve salaries, the new regime’s ₹26,000 is ₹2,167 a month out of ₹1,08,333 of monthly gross. The old regime with nothing claimed would be ₹16,250 a month. TDS is recalculated as pay and declarations change, so individual months can differ.

If ₹13,00,000 is your CTC rather than your gross — basic at 40%, the employer’s provident fund inside it and ₹200 a month of professional tax — gross salary is lower, new-regime tax is nil and about ₹95,133 a month (₹11,41,600 a year) reaches your account; the in-hand page for 13 LPA has that payslip line by line.
