The four labour codes took effect 21 November 2025. Most coverage says your take-home will fall. For a large number of employees it will not change at all — and that turns on one thing this calculator asks you about.
The 50% rule is not a rule that basic must be half your CTC. It is an add-back — and the difference matters.
Almost every article says “basic must now be at least 50% of CTC”. The statute says no such thing. Section 2(y) of the Code on Wages, 2019 provides that where the excluded components under clauses (a) to (i) exceed one-half of all remuneration, the excess is deemed to be remuneration and is added into wages.
Your employer may keep allowances above 50%. The consequence is simply that the excess is treated as wages for PF, gratuity and the rest. The arithmetic often lands in a similar place, which is why the shorthand survives — but the mechanism is a deeming provision, and on a CA site that distinction matters.
Gratuity (clause j) and retrenchment compensation (clause k) sit outside the 50% test entirely. They are excluded from wages and they do not enter the denominator. Including them, as several online calculators do, distorts the result.
And the 50% figure is not fixed in stone — the section reads “or such other per cent. as may be notified by the Central Government”. It can be changed without amending the Code.
If your employer computes PF on the ₹15,000 statutory ceiling — employee PF of exactly ₹1,800 a month — then raising your basic changes nothing for PF, and your take-home is unaffected. If your employer computes PF on actual wages, as many IT and MNC employers do, a higher wage base means a higher deduction and lower cash in hand.
Check your payslip before believing any figure, including ours.
Notified 29 June 2026, it replaced the 1952 scheme. The ceiling, the 12% rate and the EPS split are unchanged. What did change: the contribution base is now “wages” as defined in the Code on Social Security — complete with this 50% deeming rule — rather than the older “basic wages”. Also, either the employee or the employer may now independently reduce or stop voluntary contributions above the ceiling; previously that needed a joint option.
The codes are in force nationally from 21 November 2025 and central rules followed in May 2026, but state rules are at very different stages — some notified, many still in draft. Your employer’s actual restructuring timeline depends on your state. Treat this calculator as showing the direction and scale, not a payslip you can hold anyone to.
