At twenty lakhs the question changes. Nobody asks whether a 20 LPA package is taxed — they ask how ₹1,66,667 a month on the offer letter becomes ₹1,44,669 in the bank. For FY 2026-27, with this page’s defaults (new regime, Karnataka, metro, 40% basic, PF on the ₹15,000 ceiling), that ₹22,000 monthly gap decomposes into exactly three parts.
The ₹22,000-a-month anatomy
- Income tax: ₹1,79,908 a year (₹14,992 a month). Two-thirds of the gap and the only part that is a true cost.
- Retirement money: ₹81,662 a year. Employer PF (₹21,600), employee PF (₹21,600), and the gratuity provision (₹38,462) — all inside the CTC, none in the payslip, all still yours eventually.
- Professional tax: ₹2,400 a year. Karnataka’s ₹200 a month.
Gross cash salary is ₹19,39,938; after the ₹75,000 standard deduction, taxable income comes to ₹18,64,938. The slabs price it at ₹1,72,988, cess adds 4%, and the annual in-hand settles at ₹17,36,030. Note the ratio: a 20 LPA earner’s effective tax is 9% of CTC, though every additional rupee is currently taxed at 20% plus cess.
The 25% slab is one hike away — sort of
The new regime’s 25% band opens at ₹20,00,000 of taxable income, a line this package has not actually reached: ₹1.35 lakh of headroom remains inside the 20% band. Under this structure the crossing happens near a ₹21,38,000 CTC — one modest hike away. Two things about that crossing are routinely misread. First, 25% will apply only to rupees above the line; the tax on everything beneath it is untouched, so no cliff exists. Second, the next genuinely expensive threshold is far away: surcharge starts at ₹50 lakh of taxable income, so between here and roughly ₹52 lakh of CTC the marginal cost of a raise moves only from 20.8% to 31.2% (rates including cess), in two steps — 25% at ₹20 lakh taxable and 30% at ₹24 lakh taxable.
What large deductions do under the old regime
This is the income where old-regime arithmetic gets its best shot, so run it honestly: §80C at the full ₹1,50,000 and rent of ₹40,000 a month — enough that the HRA exemption maxes out at the entire ₹4,00,000 of HRA received — bring the old regime down to ₹2,22,311. The new regime computes ₹1,79,908 with no declarations at all, a difference of ₹42,403 in this calculation. What could move that result is precisely what this simplified model leaves out: §24(b) home-loan interest up to ₹2,00,000, employer NPS under §80CCD(2), §80D health premiums. Filers carrying two or more of those run the numbers both ways every April — the old-vs-new tool below does it from one input set.
Gurugram on ₹1.44 lakh a month
Gurugram takes a bigger bite of this salary than its payslip suggests. Golf Course Road and Sector 56 2BHKs run ₹35,000–₹55,000; DLF phases and Sohna Road soften that somewhat. Daily costs sit near Bengaluru levels, and the annual surprise is school-admission season rather than rent inflation. One genuine payslip perk: Haryana levies no professional tax, so against the Karnataka default used above, a Gurugram payslip quietly keeps the ₹2,400 a year — the rare line item where Delhi NCR is cheaper than the southern metros.
