1How much tax do I pay on a Rs 13 lakh salary?
About Rs 26,000 in the new regime — because marginal relief caps the tax at roughly the Rs 25,000 by which your income (after the Rs 75,000 standard deduction) exceeds Rs 12,00,000, plus 4% cess.

ArticleA Rs 13 lakh salary sits just above the Rs 12 lakh zero-tax line, and this is where a little-known rule — marginal relief — makes a big difference. Here's the real number. Figures are for the new regime, salaried, with no other income; your actual tax depends on your full situation.

Quick answer
On a Rs 13 lakh salary, marginal relief keeps the new-regime tax to about Rs 26,000 — far less than the slabs alone suggest. Here's why.
Under the new regime, the Rs 75,000 standard deduction brings a Rs 13 lakh salary to Rs 12,25,000 taxable — just Rs 25,000 above the Rs 12,00,000 rebate ceiling. Crossing that line means the 87A rebate no longer fully applies, so some tax becomes payable.
Without relief, the slab tax on Rs 12,25,000 would be around Rs 63,750 — absurdly more than the Rs 25,000 by which you crossed the line. Marginal relief prevents this: it caps your tax at the amount by which your income exceeds Rs 12,00,000. So the tax is limited to about Rs 25,000, plus 4% cess — roughly Rs 26,000.
Marginal relief applies in a band just above Rs 12,00,000 (up to roughly Rs 12.75 lakh of income), keeping tax gentle for those who barely cross the rebate line. It's why a Rs 13 lakh earner pays far less than a naive slab calculation suggests — a detail many people and even calculators get wrong.
Because you're only just over the line, a modest deduction that survives in the new regime — like employer NPS under 80CCD(2) — can pull your taxable income back to Rs 12,00,000 and restore zero tax. At this income, small moves have an outsized effect.
In the old regime, Rs 13 lakh faces a much higher base tax, so you'd need substantial 80C, NPS, HRA and home-loan interest to get below the new regime's roughly Rs 26,000. For most, the new regime with marginal relief wins here.
About Rs 26,000 in the new regime — because marginal relief caps the tax at roughly the Rs 25,000 by which your income (after the Rs 75,000 standard deduction) exceeds Rs 12,00,000, plus 4% cess.
A rule that limits your tax to the amount by which income exceeds Rs 12,00,000 , so you don't pay the full slab tax for barely crossing the rebate line. It's why Rs 13 lakh pays far less than the slabs alone suggest.
Possibly — a small deduction like employer NPS under 80CCD(2) can bring taxable income back to Rs 12,00,000 and restore zero tax, since you're only just over the line.
