CTC vs In-Hand Salary: Which Tax Regime Wins in 2026?

Say your offer letter reads Rs 15,00,000 CTC. That’s the number on the top line of the PDF, the one everyone congratulates you on, and it is not the number that ever lands in your bank account, what most people actually mean when they type “in hand salary calculator” into Google. Employer PF contribution, professional tax, your own PF deduction, and income tax all sit between that Rs 15,00,000 and your real monthly credit, and how big that gap is swings by tens of thousands of rupees a year depending on one choice you make every time you file: old tax regime or new.

New regime became the default filing option after the Finance Act 2023. Budget 2025 then pushed its tax-free threshold considerably higher. Per the government’s own press release, roughly nine out of ten salaried taxpayers now pay zero income tax under it, on salary income up to about Rs 12,75,000.^[1] That single change is a big part of why old regime vs new regime matters less than people assume for a large slice of earners, and more than people assume once CTC climbs past that line.

What Actually Happens Between Your CTC and Your First Payslip

CTC is an accounting figure built for the company’s books, not a promise about what lands in your account. It typically bundles basic salary, HRA, a special allowance bucket, and the employer’s own PF contribution into one headline number. The employer’s PF contribution (usually 12% of basic) never touches your monthly payslip: it goes straight into your EPF account rather than your bank. Some offer letters also carve out a gratuity provision, roughly 4.81% of basic, but that only pays out if you leave after five continuous years of service, and even then as a lump sum rather than a monthly credit. Our calculator, and the model I run below, treats CTC as cash salary plus that employer PF line and does not carve gratuity out as its own deduction, so if your offer letter itemizes it separately your gross will run a touch below what you see here.

From what’s left, called gross salary, three more things get subtracted before you see a rupee: your own PF contribution (also 12% of basic, though this portion is yours, just locked up until retirement or resignation), professional tax if your state charges one, and income tax under whichever regime applies to you. Karnataka’s professional tax works out to something close to Rs 2,400 a year; several states, Delhi among them, don’t charge it at all. I’d check your own state’s schedule rather than assume mine holds everywhere, because it genuinely doesn’t.

New Regime vs Old Regime, in Plain Terms

Both regimes tax the same gross salary, just with different math. New regime is the default and applies unless you opt out. The FY 2026-27 slabs run as follows, confirmed against the income tax department’s own portal and cross-checked against ClearTax.

^[2][3] It comes with a flat Rs 75,000 standard deduction and, more usefully, a Section 87A rebate of up to Rs 60,000 that wipes out tax completely if taxable income sits at or below Rs 12,00,000. That’s why gross salary up to roughly Rs 12,75,000 lands at zero tax for most salaried filers: standard deduction gets you to Rs 12,00,000 taxable, and the rebate does the rest. Right at that edge, a separate marginal relief provision kicks in so one extra rupee of income can’t suddenly cost you thousands in tax. I’m not going to try to compute that adjustment by hand here, and I wouldn’t trust a blog post that did it casually either.

Old regime is opt-in now, and its slabs are older and blunter: nil up to Rs 2,50,000, 5% up to Rs 5,00,000, 20% up to Rs 10,00,000, 30% above that. Standard deduction is lower, Rs 50,000, and the 87A rebate caps out at Rs 12,500 and only applies if taxable income is at or below Rs 5,00,000, a much lower bar than new regime’s. Old regime gives you something different. It lets you subtract real spending before tax applies. That means an HRA exemption (the smallest of actual HRA received, rent paid minus 10% of basic, or 50% of basic in a metro / 40% outside one), plus up to Rs 1,50,000 under Section 80C for things like PF, ELSS, PPF, or life insurance, and separately, Section 80D deductions for health insurance premiums. None of that exists in new regime.

The Actual Math: Three CTC Levels, Both Regimes

Numbers convince more than rules do, so I built a small model and ran it at three CTC levels: Rs 8,00,000, Rs 15,00,000, and Rs 25,00,000. One consistent set of assumptions runs through all three. Basic salary at 50% of CTC. HRA at 50% of basic, roughly what a metro employee paying reasonable rent could claim in full. The full Rs 1,50,000 Section 80C deduction (which usually happens automatically through your own EPF contribution, so claiming it often costs you nothing extra), and Karnataka’s professional tax. Your own CTC structure will differ, sometimes by a lot, so treat this as a shape, not a personal quote.

At Rs 8,00,000 CTC, it genuinely doesn’t matter. Both regimes land you at zero tax (taxable income comes in under both new regime’s Rs 12,00,000 threshold and, with HRA and 80C applied, old regime’s Rs 5,00,000 one), so the monthly in-hand figure is identical to the rupee: Rs 58,467. The two higher levels are where it gets interesting, and not in the direction I expected. At Rs 15,00,000, old regime wins, but by Rs 65 a month, roughly Rs 780 across the whole year. At Rs 25,00,000 the winner flips: new regime pulls ahead, by Rs 108 a month. Same person, same assumptions, and the better regime changes as the salary climbs. I had assumed old regime would hold its lead and just widen it, given that it allows a full Rs 5,00,000 more in deductions than new regime’s flat standard deduction at the Rs 15,00,000 level. It doesn’t, and the reason is worth a paragraph of its own.

The mechanism is worth spelling out, because the flip is the whole story here. At Rs 15,00,000, old regime’s stack of deductions (HRA, the full 80C, standard deduction) pulls taxable income down to Rs 8,35,000, keeping most of it in the 5% and 20% slabs, and that is enough to nose ahead of new regime’s Rs 13,35,000 taxable base. At Rs 25,00,000, those same deductions still shave off the same Rs 5,00,000 or so, but now a large chunk of old-regime income sits in its 30% band above Rs 10,00,000, while new regime’s more graduated ladder tops out at 25% for this taxable income. New regime’s gentler slabs overtake old regime’s fatter deductions once income climbs high enough, and the crossover point lands somewhere between these two salary levels.

So Who Actually Wins the Old-vs-New Argument?

For most salaried employees, the honest answer is that it barely matters, and where it does, new regime is the safer default because it wins or ties without any paperwork: no rent receipts to file, no 80C investment decision made under deadline pressure every February. The one level in my table where old regime actually won, Rs 15,00,000, it won by Rs 65 a month. That is a rounding error set against the effort of documenting every deduction, and as the Rs 25,00,000 row shows, it can vanish or reverse entirely with a change in income. Old regime being ahead at your current salary is not a promise it stays ahead at your next one.

Old regime pulls meaningfully ahead in one specific situation: you’re carrying a home loan. Add a full Rs 2,00,000 interest deduction under Section 24(b) to the Rs 25,00,000 scenario, holding every other assumption identical to the table, and the result doesn’t just narrow, it flips back the other way. Old regime goes from losing by Rs 108 a month to winning by about Rs 5,092 a month, close to Rs 61,100 a year. That deduction lands entirely inside old regime’s 30% band, so every rupee of home loan interest buys back more than 31 paise once you count the 4% cess, and that is finally enough to overpower new regime’s slab advantage at this income. A home loan is the single input that reliably tips a high earner back toward old regime.

My honestly contrarian take: most people spend more anxiety on this decision than it earns back. Below roughly Rs 12,75,000 gross salary, new regime already puts you at zero tax. You do nothing. Chasing old regime under that line usually just means locking money into an ELSS fund or an insurance policy you wouldn’t otherwise have bought, to claim a deduction that saves you nothing once new regime has already zeroed your tax. I don’t have a clean answer for freelancers or consultants filing under presumptive taxation, this whole piece is scoped to salaried CTC structures, and that’s a meaningfully different calculation.

Where the Salary Calculator Comes In

Doing this arithmetic by hand for your specific CTC, rent, and investments is tedious, and it’s easy to get slightly wrong. That’s most of why we built LastRound AI’s salary calculator. Enter your CTC once and it works out India take-home under old and new regime side by side, automatically, along with the same breakdown for the US, UK, and Canada if you’re weighing an offer abroad, useful if you want to see how the same salary compares across countries. If the number on the table is north of Rs 25,00,000, our breakdown of what FAANG actually pays in 2026 is a useful sanity check on levels versus total comp, and our guide to negotiating tech salaries covers what to do once you actually have a number to push back on.

FAQ

Which tax regime should I choose in 2026?

For most salaried employees earning under about Rs 12,75,000 gross, choose new regime. You likely owe zero tax either way, with far less paperwork. Above that figure, run your actual HRA, 80C, and any home loan interest through a calculator first. Old regime only pulls meaningfully ahead once those deductions get large, particularly with a home loan in the mix.

Can I switch between old and new regime every year?

If you’re salaried with no business or professional income, yes, you can pick either regime freely at ITR filing time each year. If you have business or professional income, switching requires filing Form 10-IEA, and once you’ve opted for old regime and later moved back to new, you get only one more lifetime switch back to old after that.^[2]

None of this is set in stone, either. Slabs moved twice between FY 2023-24 and FY 2026-27, and there’s no reason to assume they’re done moving. Recompute at every appraisal cycle. Doing it once, the year you join, and never again is how people overpay for years without noticing.
