Bonus is salary taxed at the applicable marginal rate; there is no separate flat bonus tax.
Bonus is salary taxed at the applicable marginal rate; there is no separate flat bonus tax. Payroll may deduct more in the payment month after revising annual tax.
Legal or Computational Framework
Bonus can move a slice into a higher slab, reduce rebate or trigger surcharge. The incremental tax is the difference between full-year tax with and without bonus.
Core working: Incremental bonus tax = annual tax including bonus − annual tax excluding bonus.
Why the result is fact-sensitive
The same keyword can produce different answers because residence, age, employment terms, service period, contribution payer, deposit type, income composition, tax regime and documentation differ. Payroll terminology is not always statutory terminology. A calculator must therefore state the legal definition used for salary, wages, contribution, deposit, deduction or exemption.
Step-by-step method
- Separate CTC, gross cash, variable pay and employer-only benefits.
- Annualise recurring earnings and place one-time items in actual months.
- Compute taxable salary and other income under the selected regime.
- Calculate annual tax before monthly collection.
- Subtract cumulative TDS and allocate the balance across payroll months.
- Reconcile payslips, bank credits, Form 16 and AIS/Form 26AS.
Worked example
Tax rises from ₹1.2 lakh to ₹2.05 lakh after ₹3 lakh bonus; incremental tax is ₹85,000, not an automatic 30%.
The example is an audit model, not a substitute for the taxpayer's records. Change one input—such as residence, regime, payment date, disability band, contribution payer, state, service period or income type—and the answer may change.
Decision checks before claiming or calculating
- Correct period: confirm whether the question concerns AY 2026–27 or Tax Year 2026–27.
- Correct statute: cite the 2025 Act for income from 1 April 2026; use the Social Security Code for current gratuity entitlement.
- Correct person: establish who paid, earned, received or is legally eligible.
- Correct base: use statutory salary, wages, interest, contribution or adjusted income—not a convenient payroll label.
- Correct ceiling: apply actual-amount, shared, lifetime and gross-total-income ceilings in the right sequence.
- Correct evidence: reconcile the result to official statements, certificates, payroll and bank records.
What Generic Pages Miss
- They risk treating TDS as final tax.
- They risk using one national rule where state law applies.
- They risk ignoring job changes.
- They risk missing proof adjustments.
- They risk not reconciling Form 16 and AIS.
They also frequently confuse a tax deduction with a tax credit, a labour entitlement with an income-tax exemption, or a monthly payroll deduction with final annual tax. Finin2min should show the accepted input, rejected input, legal reason and tax impact separately.
Practical Documentation Checklist
- payslips
- Form 12BB/proofs
- prior-employer statement
- bonus/arrears record
- state challans where relevant
- AIS/Form 26AS

Finin2min Summary
Bonus is salary taxed at the applicable marginal rate; there is no separate flat bonus tax. Payroll may deduct more in the payment month after revising annual tax.
Tax Year 2026–27 means income earned from 1 April 2026 under the Income-tax Act, 2025. It is different from AY 2026–27, which covers FY 2025–26 under the Income-tax Act, 1961. Legacy section labels are retained only to match genuine search language.
The practical result should be traceable to documents and a visible computation. A statutory maximum is a ceiling, not an automatic entitlement.
