Tax & salary
CTC vs in-hand vs Form 16
CTC is a marketing bundle. In-hand is what hits the bank after PF, professional tax, and TDS. Form 16 is the employer’s annual story for the tax department. They will not match a random online calculator, including mine, and that is fine. The useful move is to know which number you are arguing about.
CTC is a brochure
Cost-to-company can include employer PF, gratuity, insurance premia, joining bonus, and “variable” that pays at 60% of target in a normal year. Recruiters quote the headline because it is large. If employer PF is inside CTC, that slice is not yours to spend. If variable is 30% of CTC, a ₹24 lakh offer can be a ₹16.8 lakh year. Run the salary calculator on fixed pay first, then again with a pessimistic variable assumption.
In-hand is a monthly event
In-hand is CTC minus the things that never hit the account: employee PF, professional tax, TDS, and sometimes food coupons or NPS. State professional tax is not one India number. The salary sketch uses a Maharashtra-ish cap as a convenience. Your state may differ. A “take-home” screenshot from a colleague in another city is not your number.
Form 16 is a year
Form 16 Part B is where perquisites, arrears, and the regime you declared show up. A calculator that never saw those will disagree. A ₹4,000 monthly gap is often employer NPS or a joining bonus sitting in CTC. A ₹40,000 gap means you typed headline CTC and payroll used a different taxable salary. Ask HR which line is “salary for tax.”
Worked example: ₹18 lakh CTC offer
Annexure says basic ₹7.2 lakh (40%), HRA ₹3.6 lakh, special allowance the rest, employer PF 12% of basic, variable ₹2 lakh. Headline CTC is ₹18 lakh. Fixed is ₹16 lakh. Type 1600000 into the salary calculator for the regime comparison, not 1800000, unless you enjoy lying to yourself in March. Then read HRA: old regime cares; new regime mostly does not. If you pay ₹30,000 rent in a metro, old regime might still be a conversation. If you live with family and pay ₹0, it is not.
Worked example: two offers, same CTC
Offer A: 50% basic, high PF, low variable. Offer B: 30% basic, fat special allowance, 25% variable. Same ₹20 lakh CTC. In-hand and Form 16 will not match. PF and the regime delta move. Compare annexures, not headlines. The calculator is a yardstick, not a referee.
What this note adds that the calculator does not
The salary page compares regimes on one CTC. This note is how to pick the CTC you type. I cannot see your ESOP, your joining bonus clawback, or your city’s professional tax. I can tell you not to paste the brochure number and then blame the tool when Form 16 arrives. For tax on a number you already computed, use the income tax calculator. For the regime decision rule, see old vs new regime.
Employee PF vs employer PF
Employee PF leaves in-hand. Employer PF often sits inside CTC and never was yours to spend. If you type headline CTC into the salary calculator, you are comparing regimes on a number that includes money that will not hit the account. That can still be a fair regime comparison if both columns use the same sketch. It is a terrible in-hand forecast. For in-hand, start from the annexure’s monthly salary and the PF the employee actually pays.
Professional tax is a state levy with caps that are not one India number. The Maharashtra-ish cap in the sketch is a convenience. If you work remotely for a company registered elsewhere, ask payroll which rules they apply. Do not argue from a calculator default.
