Overtime Rules in India: What Every Employer Must Know
Overtime — work performed beyond the statutory working hours — is one of the most regulated aspects of employment law in India. Every major labour legislation — the Factories Act, 1948, the Kerala Shops and Commercial Establishments Act, 1960, the Minimum Wages Act, 1948, and the new Occupational Safety, Health and Working Conditions (OSH) Code, 2020 — contains specific provisions governing overtime. Understanding these rules is essential because overtime violations are among the most common findings during labour inspections, and the financial liability for unpaid overtime can be substantial.
The core principle across all statutes is consistent: overtime must be compensated at TWICE the ordinary rate of wages. This article explains how to calculate the ordinary rate, apply the overtime multiplier, track overtime hours within statutory limits, and maintain compliant records. Use our Overtime Calculator for instant computation of overtime wages for any employee.
Statutory Working Hours and Overtime Limits
Different statutes apply depending on the nature of the establishment:
- Factories Act, 1948: Maximum 9 hours per day, 48 hours per week. Overtime limit: Maximum 60 hours per week including overtime. Maximum 50 hours of overtime in any quarter (3 months). Weekly holiday mandatory.
- Kerala Shops & Commercial Establishments Act: Maximum 8 hours per day, 48 hours per week. Overtime limit: Maximum 10.5 hours per day including overtime. Maximum 50 hours of overtime in any quarter. Read our comprehensive Shop Act Compliance Guide.
- Minimum Wages Act: If minimum wage is fixed for the day, overtime rate must be double the ordinary rate. Our Minimum Wages Kerala guide explains the base rate computation.
Overtime Wage Calculation: Step by Step
The formula for overtime wages is:
Overtime Wages = Ordinary Rate of Wages × 2 × Overtime Hours Worked
Where: Ordinary Rate of Wages = (Total Monthly Wages ÷ 30) ÷ 8
Example: An employee earning ₹18,000 per month works 2 hours of overtime on a given day. Ordinary rate = (₹18,000 ÷ 30) ÷ 8 = ₹75 per hour. Overtime rate = ₹75 × 2 = ₹150 per hour. Overtime wages for that day = ₹150 × 2 = ₹300.
Monthly wages for this calculation include basic wages + dearness allowance + retaining allowance (if any). Cash value of food concessions and other amenities are excluded. For employees paid on a piece-rate basis, a different computation method applies — contact GHR Consultancy for guidance.
For factories, under Section 59 of the Factories Act, the ordinary rate also includes any cash equivalent of advantages accruing from the supply of materials. This is an area where many employers under-calculate overtime liability. Use our Overtime Calculator to eliminate manual calculation errors.
Overtime Register: The Most Scrutinised Record
During labour inspections, the Overtime Register is consistently one of the most intensely examined documents. It must record:
- Date of overtime work
- Employee name and designation
- Overtime hours worked (start time and end time)
- Ordinary rate of wages applied
- Overtime rate (must be double the ordinary rate)
- Total overtime wages paid for that instance
- Employee signature acknowledging receipt of overtime wages
Common violations: Overtime register not maintained at all, hours worked but not recorded, overtime paid at single rate instead of double, cumulative overtime exceeding quarterly limit (50 hours), employee signatures missing, register not produced during inspection.

Overtime Calculation for Night Shift and Weekly Holidays
Overtime computation becomes more complex when applied to night shifts, weekly holidays, and public holidays. Each scenario has distinct rules that employers must understand to avoid computational errors:
- Night shift overtime: Under the Factories Act, 1948, work performed between 7 PM and 6 AM is considered night shift. In Kerala, women are generally prohibited from working night shifts (with certain relaxations for IT/ITeS establishments under the Kerala Shops Act amendment). For men working night shifts, the same overtime rules apply (double the ordinary rate), but the entire night shift hours count toward the daily maximum of 9 hours (or 8 hours under the Shops Act). Importantly, if an employee works a night shift that extends beyond midnight, the hours after midnight count as part of the NEXT day's working hours for the purpose of calculating the daily maximum — not the previous day's. This is a common computational error in Kerala establishments that operate 24/7.
- Weekly holiday overtime: If an employee is required to work on their designated weekly holiday (typically Sunday), they are entitled to: (a) overtime wages at double the ordinary rate for that day, plus (b) a compensatory holiday within the next 7 days. The compensatory holiday is separate from the overtime pay — both are mandatory. This is a frequently violated requirement because many employers assume paying overtime at double rate is sufficient. It is not.
- National and festival holiday overtime: Working on national holidays (Republic Day, Independence Day, Gandhi Jayanti) or notified festival holidays (Onam, Vishu, Thiruvonam in Kerala) attracts overtime at double the ordinary rate, plus a compensatory holiday. The employer must also ensure that the total overtime in any quarter does not exceed 50 hours (Shops Act) or 75 hours (Factories Act) — even if the holiday overtime pushes the quarterly total over the limit.
- Calculating overtime for piece-rate workers: For piece-rate workers, the "ordinary rate of wages" for overtime calculation is the time rate equivalent of the piece-rate wages. This is computed as: (Total piece-rate wages earned in the previous month ÷ total hours worked in that month) × 2 for overtime. This calculation is complex and often miscalculated, leading to inspection findings. Our Overtime Calculator supports computations for both time-rate and piece-rate workers.
- Overtime for supervisors and managers: Employees in managerial or supervisory positions drawing wages above a prescribed threshold (₹21,000 per month or such limit as notified) are exempt from overtime provisions under certain conditions. However, the exemption is NOT automatic — it depends on the nature of the duties performed, not just the job title or salary level. An employee with a "supervisor" title who performs primarily operational tasks rather than managerial functions may still be entitled to overtime. Kerala labour inspectors examine the actual job content, not the designation.
For employers managing overtime across multiple shift patterns and worker categories, maintaining an accurate overtime register is the single most important compliance activity. Our Payroll Services include automated overtime computation, register maintenance, and quarterly limit tracking to ensure your establishment never exceeds statutory maximums or misses an overtime wage obligation.

Exemptions and Special Cases
Certain categories may be exempt from overtime provisions under specific conditions: employees in managerial or supervisory positions drawing wages above a prescribed threshold, employees in positions of confidential nature, and workers in certain essential services. However, the exemption criteria are narrow and fact-specific. Assuming an exemption without legal verification is risky — during an inspection, the burden of proof lies with the employer.
