Statutory Bonus in India: An HR Practitioner's Calculation Playbook

An HR-side playbook for the bonus cycle: eligibility roster, the ₹7,000 vs minimum-wage cap, allocable-surplus working, set-on / set-off, the four forms, and the November deadline. Worked example for an 80-worker unit.

The Short Version

Under the Payment of Bonus Act 1965, every establishment with 20 or more employees must pay an annual bonus to employees earning ₹21,000 or less per month, between a floor of 8.33% and a ceiling of 20% of the bonus-qualifying wages. The calculation base is capped at ₹7,000 per month or the relevant minimum wage, whichever is higher. Bonus is payable within eight months of the financial year close. Misreading the eligibility, the wage ceiling, or the calculation cap is the most common compliance miss in Indian payroll, and it usually surfaces only when a labour officer asks for Form C.

Why This Matters

Statutory bonus is one of those areas where the law is unambiguous and yet the practice is messy. Two patterns repeat. First, mid-sized companies treat the 8.33% as a fixed monthly accrual paid through the payslip, then forget that an employee earning over ₹21,000 should not even be in the calculation. Second, larger employers pay generous discretionary bonuses and assume the statutory obligation is automatically met, without ever testing whether the discretionary amount actually clears the 8.33% floor for each eligible head.

Both patterns hold until an inspection. Form D (the annual return) sits on the inspector's desk; Form C (the bonus register) needs to match it; Form A and B (the allocable surplus and the set-on / set-off statements) need to be produced on demand. A messy bonus practice that nobody complained about for five years can produce arrears with interest in a single morning.

For employees, the stakes are smaller in absolute rupees but high in trust. A worker on ₹18,000 a month who is told "sorry, no bonus this year" while the company posts a profit has a strong claim, and word travels fast.

The Core Concept

Who Does the Act Apply To?

The Payment of Bonus Act 1965 (POBA) covers every factory under the Factories Act 1948 and every other establishment employing 20 or more persons on any day during an accounting year. Once covered, an establishment continues to be covered even if headcount falls below 20, until the lower number persists for the full accounting year (and only after notification).

Employees in the public sector are covered only in specific cases (those competing with private sector entities). Government employees, university staff, RBI employees, and certain other specified categories are excluded under §32.

Who is Eligible?

An employee qualifies for bonus under §8 if they have worked at least 30 working days in the accounting year, and their salary or wage does not exceed ₹21,000 per month. The ₹21,000 ceiling was set by the 2015 amendment, with retrospective effect from 1 April 2014.

Salary or wage under §2(21) means basic plus dearness allowance. It does not include HRA, overtime, bonus itself, commission, or reimbursements. So an employee with ₹19,000 basic + DA and ₹6,000 HRA is at ₹19,000 for the eligibility test, not ₹25,000.

The 8.33% Floor and the 20% Ceiling

Under §10 and §11, the minimum bonus is 8.33% of bonus-qualifying wages, payable even if the employer has no allocable surplus or has incurred a loss. The maximum is 20%. The actual percentage between these limits depends on the allocable surplus computed under the Act's mechanism (§4 to §7).

For the first five accounting years from the date the establishment starts to sell or render services, the minimum bonus rule is relaxed: bonus is payable only when the establishment derives profit from such accounting years. After year five, the 8.33% minimum applies regardless of profit.

The ₹7,000 Calculation Cap

This is the rule most HR teams get wrong. Even if an employee earns ₹19,500 a month (and is therefore eligible), the bonus is calculated on a deemed wage of ₹7,000 or the minimum wage for the scheduled employment, whichever is higher, under §12.

So an eligible employee in Maharashtra working in an industry where the minimum wage is ₹14,500 has bonus computed on ₹14,500. The same employee in a state or industry where the minimum wage is ₹6,800 has bonus computed on ₹7,000. The actual ₹19,500 they take home is irrelevant for the bonus base.

This was settled by the 2015 amendment, replacing the earlier ₹3,500 cap. It often surprises HR teams who assume the calculation is simply 8.33% of actual basic + DA.

A Worked Example

Scenario: A Pune Manufacturing Unit, 80 Workers, FY 2024-25

The company has 80 production-floor workers. Their monthly basic + DA averages ₹16,500. The relevant Maharashtra minimum wage for unskilled workers in this scheduled employment is ₹14,200. Annual working days per worker average 280.

Step 1: Eligibility. All 80 workers earn under ₹21,000 a month and have crossed 30 working days. All 80 are eligible.

Step 2: Bonus base per worker. Higher of ₹7,000 or the relevant minimum wage = max(₹7,000, ₹14,200) = ₹14,200 per month per worker.

Step 3: Calculate the floor (8.33%).

Per worker per month: 14,200 × 8.33% = ₹1,182.86
Per worker per year: 1,182.86 × 12 = ₹14,194
Total floor for 80 workers: 14,194 × 80 = ₹11,35,520

Step 4: Calculate the ceiling (20%).

Per worker per year: 14,200 × 20% × 12 = ₹34,080
Total ceiling for 80 workers: 34,080 × 80 = ₹27,26,400

Step 5: Determine the actual %. The company computes its allocable surplus per §4–§7. Suppose the available surplus translates to 12.5% as the percentage of bonus-qualifying wages. Then total bonus payable = ₹14,200 × 12.5% × 12 × 80 = ₹17,04,000, or roughly ₹21,300 per worker for the year.

The unit pays this in a single cheque before 30 November 2025 (within eight months of the 31 March 2025 close) and files Form D with the labour office for FY 2024-25.

What if a Worker Has Worked Less Than 240 Days?

Pro-rata applies under §13. A worker who completed 168 working days out of an expected 280 receives 168/280 × full annual bonus. So if the full bonus per worker is ₹21,300, the part-year worker receives 21,300 × 168 / 280 = ₹12,780.

What About Disqualification?

Under §9, an employee dismissed for fraud, riotous or violent behaviour at the workplace, or theft is disqualified from receiving bonus for that accounting year. Documentation of the misconduct and the disciplinary process is essential. Casual disqualification fails in court.

Allocable Surplus: The Math Behind the %

The Act builds the bonus pool through a defined mechanism (§4 to §7), then sets the percentage by dividing this pool by the total bonus-qualifying wages.

  1. Gross profits are computed under §4, broadly per the Second Schedule (banking) or Third Schedule (other establishments). Start with profit before tax and add back specific items.
  2. Available surplus = gross profits − depreciation under §32 of the Income Tax Act − development rebate / investment allowance − direct taxes payable.
  3. Allocable surplus = 67% of available surplus (60% for banking companies). For Section 25 companies and a few other categories the rate differs.
  4. Set-on / set-off: under §15, surplus exceeding 20% of wages is carried forward as "set-on" for up to four years. A shortfall below the 8.33% minimum becomes "set-off" against future surpluses.

The set-on / set-off mechanism is what allows employers to pay 20% in profitable years while still meeting the 8.33% floor in lean ones. Most mid-sized employers should be tracking this on Form B, not in a one-off spreadsheet.

Common Mistakes

  1. Paying bonus to ineligible employees and not paying the eligible ones. Treating bonus as a flat "one month's salary" perk paid to everyone, including managers earning ₹3L a month, while the legally entitled production worker is told there is no bonus this year, gets the law backwards. Eligibility is income-tested.
  2. Using actual basic + DA as the calculation base. The Act caps the calculation at ₹7,000 or the minimum wage, whichever is higher. Calculating on ₹18,000 actual when the cap is ₹14,200 inflates the obligation; calculating on the actual ₹6,500 when the floor is ₹7,000 understates it.
  3. Skipping the 30-day test. A new joiner who worked only 22 days in the year is not eligible, even if the base salary qualifies. Equally, an employee who exited before completing 30 days for the year is not entitled.
  4. Missing the eight-month deadline. §19 mandates payment within eight months of the financial year close. For an FY ending 31 March, the latest date is 30 November. Beyond this, a labour-office complaint can produce arrears with interest, and prosecution under §28.
  5. Not maintaining Form A, B, C, D. Form A is the allocable surplus computation. Form B is the set-on / set-off register. Form C is the bonus register (per employee). Form D is the annual return. Inspectors ask for all four; reconstructing them six months later is painful.
  6. Confusing performance bonus with statutory bonus. Discretionary performance bonuses paid against KPIs are separate from the statutory bonus owed under POBA. A common shortcut is to label the performance bonus as "statutory + ex-gratia". That is fine, as long as the statutory portion is computed correctly and shown separately on the bonus voucher.
  7. Treating dearness allowance inconsistently. DA is part of "salary or wage" for both eligibility and calculation. If your payroll has stopped using DA but still has it sitting on the structure as ₹0, eligibility math under-counts.

HR Compliance Checklist

  • For each financial year, run an eligibility report on 31 March: every employee with monthly basic + DA at or below ₹21,000 and at least 30 working days in the year goes on the list.
  • Compute the bonus base for each eligible employee as the higher of ₹7,000 or the relevant minimum wage notification for the scheduled employment.
  • Pull the latest minimum wage notification for the state and industry. Maharashtra, Karnataka, Tamil Nadu, and West Bengal revise these annually or semi-annually.
  • Build the allocable surplus working (Form A) using the latest audited financials. Apply the set-on / set-off carry-forwards from prior years (Form B).
  • Calculate the bonus % between 8.33% and 20% based on the allocable surplus available per worker.
  • Apply pro-rata for part-year employees and adjust for any §9 disqualifications, with documented disciplinary records.
  • Pay the bonus before 30 November (for an FY ending 31 March). Issue an individual bonus voucher to every employee showing the base, the rate, and the gross.
  • Treat statutory bonus as taxable salary in the year of payment. It is taxed at slab rates; no separate exemption applies.
  • File Form D with the appropriate labour authority within 30 days of bonus payment.
  • Retain Forms A, B, C, D for at least three years after the close of the accounting year.

What Good Payroll Software Should Do

  • Auto-flag the eligibility list every March. The system should check basic + DA against the ₹21,000 threshold and the 30-day rule, then produce the eligibility roster without HR having to filter manually.
  • Apply the higher-of-₹7,000-or-minimum-wage cap correctly. Indian HRM's payroll module pulls the latest minimum-wage notifications by state and scheduled employment so the bonus base is right by default, not based on a hardcoded ₹7,000.
  • Maintain Form B set-on / set-off automatically. When the actual percentage paid is above 20%, the surplus rolls forward; below 8.33% (paid out of statutory minimum), the gap rolls into set-off. Tracking this in spreadsheets across years is where most errors creep in.
  • Generate Forms A, C, D on demand. When the inspector calls, the data should be one report away, not a week of reconstruction.
  • Issue individual bonus vouchers. Each eligible employee gets a clear breakdown: bonus base used, rate applied, gross bonus, TDS implication. Same transparency standard as a payslip.

Frequently Asked Questions

Is bonus mandatory even in a loss-making year?

Yes. After the first five years of operation, the 8.33% minimum bonus is payable to every eligible employee regardless of whether the establishment earned a profit. The minimum is statutory, not contingent on profitability.

Is the statutory bonus the same as a Diwali bonus?

Not necessarily. "Diwali bonus" is a colloquial term for whatever the company chooses to pay around the festival. If the company is POBA-covered and has eligible employees, the statutory bonus must be paid, regardless of whether it coincides with Diwali. Many employers schedule the statutory payment to land before Diwali, which is fine, but the legal obligation exists independently of the festival.

What is the tax treatment of statutory bonus?

Bonus is fully taxable as salary income in the financial year of payment. TDS under §192 applies. There is no separate exemption (unlike, say, gratuity under §10(10) or HRA under §10(13A)).

If an employee resigns before bonus is paid, do they still get it?

Yes, provided they meet the 30-day eligibility for the relevant accounting year. The employer is liable to pay the bonus pro-rata for the months they worked, even if they have already left. This often gets bundled into the full-and-final settlement.

Can the bonus be paid as a loan or adjusted against an advance?

No. §11 read with the Act's spirit treats bonus as a payment on its own. Adjusting it against advances or treating it as a loan repayment is not permitted and has been struck down in inspections.

The Bottom Line

The Payment of Bonus Act is short, the math is fixed, and the deadlines are clear. The trouble is process. Most violations come from HR teams that never built an eligibility roster, never tracked the minimum-wage notification correctly, or treated the discretionary year-end pay-out as a substitute for the statutory calculation.

Get the four forms (A, B, C, D) on a yearly cycle, run the eligibility check the same week you close the books, and pay before 30 November. The compliance risk drops to near-zero, the audit conversation gets short, and the eligible employees see a clear, dated, documented bonus voucher every year. That is the entire job.
