Rohit joined a ₹90.5 lakh role as a software engineer in Bengaluru and had to pick a tax regime on the joining form. New regime: ₹4,50,439 a month, income tax of ₹23,38,684 a year. Old regime with no real deductions: ₹4,27,559 a month, because ₹90.5 lakh gets taxed ₹26,13,244 there. Same CTC, ₹22,880 a month difference, decided by one checkbox.
What ₹90.5 lakh CTC actually contains
Standard 50% basic structure at ₹90.5L:
| Component | Annual | Monthly |
|---|---|---|
| Basic salary | ₹45,25,000 | ₹3,77,083 |
| HRA (50% of basic) | ₹22,62,500 | ₹1,88,542 |
| Special allowance | ₹15,01,848 | ₹1,25,154 |
| Employer PF (12% of basic) | ₹5,43,000 | ₹45,250 |
| Gratuity provision (4.81%) | ₹2,17,653 | ₹18,138 |
| Total CTC | ₹90,50,000 | ₹7,54,167 |
Employer PF plus gratuity comes to ₹7,60,653. That money sits inside the ₹90.5 lakh CTC and never lands in your salary account. Your gross salary, the part payroll actually pays, is ₹82,89,348 a year.
Take-home calculation (new regime)
| Item | Annual | Monthly |
|---|---|---|
| Gross salary (excl. employer PF + gratuity) | ₹82,89,348 | ₹6,90,779 |
| Less: Employee PF | ₹5,43,000 | ₹45,250 |
| Less: Professional tax (Karnataka) | ₹2,400 | ₹200 |
| Less: Income tax | ₹23,38,684 | ₹1,94,890 |
| In-hand | ₹54,05,263 | ₹4,50,439 |
Tax working: gross ₹82,89,348 minus the ₹75,000 standard deduction leaves taxable income of ₹82,14,348. Slab tax works out to ₹20,44,304, and after cess the final income tax is ₹23,38,684.
New regime vs old regime at this salary
Under the new regime, income tax works out to ₹23,38,684 a year. Switch to the old regime with no major deductions and the same ₹90.5 lakh is taxed ₹26,13,244 a year, pulling monthly in-hand down to ₹4,27,559. That’s a gap of ₹2,74,560 a year, gone for ticking the wrong box.
The old regime only catches up if you genuinely stack deductions: the full ₹1.5 lakh under 80C, ₹25,000 of 80D health cover, ₹50,000 of NPS under 80CCD(1B), and real HRA exemption from rent paid. Without most of that, stay on the new regime. Run your actual numbers both ways in the take-home calculator before you commit on the joining form.
How take-home moves across the salary ladder
