Ten lakhs is the first CTC that sounds like ₹1 lakh a month — and the payslip promptly disagrees. For FY 2026-27 the real number is about ₹77,931 a month with the defaults used on this page (new regime, Karnataka, metro, 40% basic, PF on the statutory ceiling). The good news hiding inside that number: income tax’s share of the gap is exactly ₹0.
How a ₹10,00,000 CTC splits five ways
- Basic salary — ₹4,00,000. The anchor; everything else is computed from it.
- HRA — ₹2,00,000. Half of basic in a metro.
- Special allowance — ₹3,59,169. The balancing figure.
- Employer PF — ₹21,600. Inside the CTC, outside your bank account.
- Gratuity provision — ₹19,231. Reserved by the employer, payable only after five years.
The first three add up to a gross cash salary of ₹9,59,169. From that, three deductions: income tax (₹0 — see below), employee PF (₹21,600), and professional tax (₹2,400). Annual in-hand: ₹9,35,169.
The ₹28,417 that never gets charged
Taxable income here is ₹8,84,169 after the ₹75,000 standard deduction. Running the new-regime slabs over it yields ₹28,417 — and then the §87A rebate, which applies in full to any taxable income up to ₹12,00,000, wipes the slate. This is worth understanding rather than just enjoying: the rebate is a cliff-edge benefit tied to the ₹12,00,000 line, not a permanent property of your salary. At 10 LPA you enjoy a comfortable ₹3.16 lakh of taxable-income cushion below that line.
Old regime at 10 LPA: a floor of ₹24,808
Feed this CTC to the old regime with everything maxed — ₹1,50,000 of §80C and enough rent that the HRA exemption saturates at the full ₹2,00,000 of HRA received — and the computation still returns ₹24,808, because the old slabs start charging 20% from ₹5,00,000. Since the new regime computes ₹0 here without a single declaration, the calculation favours it at every deduction level a 10 LPA earner can realistically reach. (Run your own combination in the old-vs-new comparison tool; the outcome is stated neutrally there too.)
What changes above 10 LPA
The interesting boundary sits about 32% away. Keep this structure and tax remains zero until roughly ₹13,22,000 of CTC, where gross salary touches ₹12,75,000 and taxable income hits the rebate limit. Between ₹10 and ₹13.22 lakh, every rupee of hike flows to in-hand minus only PF increments. Just past the line, the marginal-relief proviso takes over so the first tax rupees stay proportionate — the cliff many people fear at “₹12 lakh” does not exist on the way up.
₹77,931 in Hyderabad
Hyderabad may be the strongest cost-of-living match for this salary among the big tech cities. Gachibowli and Kondapur 2BHKs rent around ₹20,000–₹30,000, meals and commutes price well below Bengaluru, and Telangana’s professional tax at this income is ₹2,400 a year (₹200 a month above a ₹20,000 monthly threshold) — identical in total to Karnataka’s. The practical effect: a 10 LPA offer in Hyderabad frequently leaves more discretionary money than a 12 LPA offer in Mumbai after rent.
