Aakash moved to a ₹13.5 lakh role as an accounts executive in Chandigarh and had to pick a tax regime on the joining form. New regime: ₹96,094 a month, zero income tax. Old regime with no real deductions: ₹81,495 a month, because ₹13.5 lakh gets taxed ₹1,75,198 there. Same CTC, ₹14,600 a month difference, decided by one checkbox. At ₹13.5 lakh the new regime wins by a distance.
What ₹13.5 lakh CTC actually contains
Standard 50% basic structure at ₹13.5L:
| Component | Annual | Monthly |
|---|---|---|
| Basic salary | ₹6,75,000 | ₹56,250 |
| HRA (50% of basic) | ₹3,37,500 | ₹28,125 |
| Special allowance | ₹2,24,032 | ₹18,669 |
| Employer PF (12% of basic) | ₹81,000 | ₹6,750 |
| Gratuity provision (4.81%) | ₹32,467 | ₹2,706 |
| Total CTC | ₹13,50,000 | ₹1,12,500 |
Employer PF plus gratuity comes to ₹1,13,468. That money sits inside the ₹13.5 lakh CTC and never lands in your salary account. Your gross salary, the part payroll actually pays, is ₹12,36,532 a year.
Take-home calculation (new regime)
| Item | Annual | Monthly |
|---|---|---|
| Gross salary (excl. employer PF + gratuity) | ₹12,36,532 | ₹1,03,044 |
| Less: Employee PF | ₹81,000 | ₹6,750 |
| Less: Professional tax (Karnataka) | ₹2,400 | ₹200 |
| Less: Income tax | ₹0 | ₹0 |
| In-hand | ₹11,53,132 | ₹96,094 |
Tax working: gross ₹12,36,532 minus the ₹75,000 standard deduction leaves taxable income of ₹11,61,532. The slab tax adds up to ₹56,153 (₹20,000 in the 5% slab, ₹36,153 in the 10% slab), but taxable income stays under the ₹12 lakh line, so the section 87A rebate of up to ₹60,000 wipes the whole amount. Tax payable: zero.
New regime vs old regime at this salary
This is the band where the regime choice is the whole game. Under the new regime, taxable income of ₹11,61,532 sits under the ₹12 lakh line, so the section 87A rebate still reaches it and income tax is zero. Switch to the old regime with no major deductions and the same ₹13.5 lakh is taxed ₹1,75,198 a year, pulling monthly in-hand down to ₹81,495. That is ₹1,75,198 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.
