Karthik joined a ₹34.5 lakh role as a operations executive in Noida and had to pick a tax regime on the joining form. New regime: ₹2,02,075 a month, income tax of ₹5,25,729 a year. Old regime with no real deductions: ₹1,81,275 a month, because ₹34.5 lakh gets taxed ₹7,75,329 there. Same CTC, ₹20,800 a month difference, decided by one checkbox.
What ₹34.5 lakh CTC actually contains
Standard 50% basic structure at ₹34.5L:
| Component | Annual | Monthly |
|---|---|---|
| Basic salary | ₹17,25,000 | ₹1,43,750 |
| HRA (50% of basic) | ₹8,62,500 | ₹71,875 |
| Special allowance | ₹5,72,528 | ₹47,711 |
| Employer PF (12% of basic) | ₹2,07,000 | ₹17,250 |
| Gratuity provision (4.81%) | ₹82,973 | ₹6,914 |
| Total CTC | ₹34,50,000 | ₹2,87,500 |
Employer PF plus gratuity comes to ₹2,89,973. That money sits inside the ₹34.5 lakh CTC and never lands in your salary account. Your gross salary, the part payroll actually pays, is ₹31,60,028 a year.
Take-home calculation (new regime)
| Item | Annual | Monthly |
|---|---|---|
| Gross salary (excl. employer PF + gratuity) | ₹31,60,028 | ₹2,63,336 |
| Less: Employee PF | ₹2,07,000 | ₹17,250 |
| Less: Professional tax (Karnataka) | ₹2,400 | ₹200 |
| Less: Income tax | ₹5,25,729 | ₹43,811 |
| In-hand | ₹24,24,899 | ₹2,02,075 |
Tax working: gross ₹31,60,028 minus the ₹75,000 standard deduction leaves taxable income of ₹30,85,028. Slab tax works out to ₹5,05,508, and after cess the final income tax is ₹5,25,729.
New regime vs old regime at this salary
Under the new regime, income tax works out to ₹5,25,729 a year. Switch to the old regime with no major deductions and the same ₹34.5 lakh is taxed ₹7,75,329 a year, pulling monthly in-hand down to ₹1,81,275. That’s a gap of ₹2,49,600 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.
