Rohit joined a ₹80.5 lakh role as a software engineer in Bengaluru and had to pick a tax regime on the joining form. New regime: ₹4,05,306 a month, income tax of ₹20,24,330 a year. Old regime with no real deductions: ₹3,82,426 a month, because ₹80.5 lakh gets taxed ₹22,98,890 there. Same CTC, ₹22,880 a month difference, decided by one checkbox.
What ₹80.5 lakh CTC actually contains
Standard 50% basic structure at ₹80.5L:
| Component | Annual | Monthly |
|---|---|---|
| Basic salary | ₹40,25,000 | ₹3,35,417 |
| HRA (50% of basic) | ₹20,12,500 | ₹1,67,708 |
| Special allowance | ₹13,35,898 | ₹1,11,325 |
| Employer PF (12% of basic) | ₹4,83,000 | ₹40,250 |
| Gratuity provision (4.81%) | ₹1,93,603 | ₹16,134 |
| Total CTC | ₹80,50,000 | ₹6,70,833 |
Employer PF plus gratuity comes to ₹6,76,603. That money sits inside the ₹80.5 lakh CTC and never lands in your salary account. Your gross salary, the part payroll actually pays, is ₹73,73,398 a year.
Take-home calculation (new regime)
| Item | Annual | Monthly |
|---|---|---|
| Gross salary (excl. employer PF + gratuity) | ₹73,73,398 | ₹6,14,450 |
| Less: Employee PF | ₹4,83,000 | ₹40,250 |
| Less: Professional tax (Karnataka) | ₹2,400 | ₹200 |
| Less: Income tax | ₹20,24,330 | ₹1,68,694 |
| In-hand | ₹48,63,667 | ₹4,05,306 |
Tax working: gross ₹73,73,398 minus the ₹75,000 standard deduction leaves taxable income of ₹72,98,398. Slab tax works out to ₹17,69,519, and after cess the final income tax is ₹20,24,330.
New regime vs old regime at this salary
Under the new regime, income tax works out to ₹20,24,330 a year. Switch to the old regime with no major deductions and the same ₹80.5 lakh is taxed ₹22,98,890 a year, pulling monthly in-hand down to ₹3,82,426. 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
