How a notice-period buyout is calculated
When you resign, your contract obliges you to keep working for the notice period — typically 30, 60, or 90 days in Indian companies. A buyout (also called notice-pay recovery or salary in lieu of notice) is the contractual price of leaving earlier: for every notice day you do not serve, you pay the employer one day of salary, and the amount is usually deducted from your full-and-final settlement rather than paid separately. The arithmetic is simple:
Buyout = monthly salary base × unserved notice days ÷ 30
So a 90-day notice with 30 days served leaves 60 unserved days, and on a ₹1,00,000 monthly base that is ₹1,00,000 × 60 ÷ 30 = ₹2,00,000. The 30-day divisor is the common contractual convention for turning a monthly salary into a day rate; some policies use the actual calendar month or working days instead, which changes the per-day price without changing the structure of the formula.
Gross or basic? The base is a contract term, not a law
No statute prescribes how buyouts are computed — the Industrial Employment (Standing Orders) rules and shops-and-establishments Acts require notice or pay in lieu for certain categories, but the salary base comes from your appointment letter. In practice companies split roughly into two camps: recovery on full monthly gross, and recovery on basic pay (plus DA where it exists). The gap is not cosmetic. A ₹12 LPA structure with 40% basic pays ₹40,000/month basic against ₹1,00,000 gross, so the same 60-day shortfall costs ₹80,000 on one reading and ₹2,00,000 on the other. The calculator's toggle exists precisely because both clauses are common — the wording in your own appointment letter or exit policy decides which one applies to you.
Recovery and reimbursement are two different transactions
Two parties can end up paying for the same unserved notice, and the tax system treats them differently. A recovery is what your outgoing employer deducts from your final settlement (or invoices you for). A reimbursement is what a new employer pays to bring you on board faster — either transferred to you or settled directly with the old company, often labelled a buyout allowance or folded into a joining bonus. They feel like one transaction from your side, but on paper they are independent: one is money flowing out under your old contract, the other is money flowing in under your new one.
The tax picture, honestly
The reimbursement side is the settled half: an amount your new employer pays you to cover the buyout is a benefit from employment and is taxed as salary income in your hands, exactly like a joining bonus. A "100% buyout reimbursement" therefore lands net of TDS — on a ₹2,00,000 buyout at a 30% marginal rate, roughly ₹60,000 of the cost stays with you unless the new employer grosses the payment up.
The recovery side is murkier. Payroll practice is to tax the salary you earned in full and treat the recovered notice pay as a separate deduction — so Form 16 usually shows gross salary with no reduction for the recovery. The Ahmedabad ITAT in Nandinho Rebello v. DCIT (2017) disagreed, holding that only salary actually received after the notice-pay recovery was taxable for that assessee. But a tribunal decision binds nobody outside its case: there is no CBDT circular adopting it, employers have not changed their Form 16 practice, and a taxpayer claiming the net figure in their return is taking a litigation position. This page explains the divergence; it does not resolve it, and a decision on how to file belongs with a qualified tax professional.
The GST question — presented as the open question it is
Whether an employer must charge GST on notice-pay recovery spent years generating conflicting advance rulings. One line of AAR decisions (Gujarat's Amneal Pharmaceuticals ruling among them) held that the employer "tolerates the act" of early exit for consideration — a deemed service taxable at 18% — and many companies duly added GST to recovery invoices. Other rulings, and later appellate authorities, took the opposite view. CBIC Circular 178/10/2022-GST then clarified that amounts recovered under an employment contract for unserved notice are compensation for breach, not consideration for an independent supply, and post-circular rulings have largely followed it. Even so, some employers continue to charge GST out of caution, and past periods remain in dispute in places. If your settlement sheet shows an 18% line on the recovery, that is the history behind it — an educational summary, not a position on any individual case.
