What Is the Minimum Number of Employees Required for PF, ESI, Gratuity, and Bonus in India?

Every Indian business owner hits the same wall at some point: “We just hired our 10th person. Do we need to register for ESI now? What about PF? When does gratuity kick in?”

These are not abstract questions. Getting the threshold wrong can cost you lakhs in penalties, interest charges, and even imprisonment under certain labour laws. And the rules are not the same across all laws. PF kicks in at 20 employees. ESI can apply at 10 in factories. Gratuity starts at 10 employees but has completely different eligibility rules.

The problem is that no single government website consolidates all these thresholds in one place. Business owners have to read through the EPF Act, ESI Act, Payment of Gratuity Act, and Payment of Bonus Act separately, and then figure out how state level laws like Professional Tax and Labour Welfare Fund layer on top.

This guide puts every applicability threshold, wage limit, contribution rate, and registration deadline in one place so you know exactly when each law applies to your business.

Now let us break down each law in detail.

1. Provident Fund (EPF): 20 or More Employees

The Employees’ Provident Funds and Miscellaneous Provisions Act, 1952 is the most common compliance trigger for growing businesses.

When Does PF Apply?

PF becomes mandatory when your establishment employs 20 or more persons on any day. This includes all types of workers: permanent, temporary, contractual, and casual employees.

PF Applicability FactorDetails
Minimum employees20 on any single day
Types of employees countedAll categories: permanent, temporary, contract, casual
Wage ceiling for contribution₹15,000/month (basic + DA)
Employee contribution12% of basic + DA
Employer contribution12% of basic + DA (3.67% to EPF + 8.33% to EPS)
Registration deadlineWithin one month of crossing the threshold
Voluntary registrationAvailable for establishments with fewer than 20 employees

The “Once Covered, Always Covered” Rule

This is one of the most critical rules that business owners miss. Once your establishment becomes covered under the EPF Act (because you had 20 or more employees), the Act continues to apply even if your employee count drops below 20 later. You cannot deregister simply because you reduced staff.

For example, if your Pune based IT services company had 22 employees in March 2026 and you registered for PF, but then 5 employees resigned in April bringing the count to 17, you still need to continue PF compliance for all remaining employees.

Voluntary PF Registration

If you have fewer than 20 employees, you can still register voluntarily. This requires consent from the employer and a majority of employees. Many startups choose voluntary registration because it helps attract talent. Employees see PF as a basic benefit, and companies offering it from day one appear more professional.

To understand how EPF contributions are calculated and the recent EPF reforms that affect contribution rates, check our detailed guides.

PF Contribution Breakdown

ComponentEmployee ShareEmployer Share
EPF (Provident Fund)12%3.67%
EPS (Pension Scheme)Nil8.33%
EDLI (Insurance)Nil0.50%
Admin chargesNil0.50%
Total12%13%

Note: The contribution is calculated on basic salary plus dearness allowance. If an employee’s basic + DA is ₹20,000 per month, the contribution is still calculated on ₹15,000 (the wage ceiling) unless the employer opts to contribute on the actual salary.

What Counts as an “Establishment” for PF?

The EPF Act applies to every establishment that is a factory engaged in any industry listed in Schedule 1 of the Act, and to any other establishment employing 20 or more persons. This covers factories, shops, offices, and virtually every type of business.

2. ESI (Employee State Insurance): 10 or 20 Employees

The Employees’ State Insurance Act, 1948 provides medical, sickness, maternity, and disablement benefits to employees.

When Does ESI Apply?

The threshold depends on the type of establishment:

Establishment TypeMinimum Employees for ESI
Factories (using power)10 or more
Factories (without power)20 or more
Shops, hotels, restaurants, cinemas, road transport, newspaper establishments20 or more (10 in some states)
Medical and educational institutions20 or more (where notified)
Private IT/ITES establishmentsAs notified by state government

ESI Wage Limit

ESI applies only to employees earning a gross salary of ₹21,000 per month or less (₹25,000 for persons with disability). If an employee’s gross salary exceeds ₹21,000, that individual employee is exempt from ESI, but the establishment must still be registered if it meets the employee count threshold.

ESI FactorDetails
Employee wage ceiling₹21,000/month gross (₹25,000 for PwD)
Employer contribution3.25% of gross wages
Employee contribution0.75% of gross wages
Total contribution4% of gross wages
Contribution period 1April to September
Contribution period 2October to March
Payment due date15th of the following month

Important: State Notifications Matter

Several state governments have notified ESI applicability for establishments with 10 or more employees, even for non-factory establishments. Before assuming the 20 employee threshold applies to your business, check the notification issued by your state government.

For instance, the ESI Corporation has been progressively expanding coverage to new areas and types of establishments. If your business operates in a recently notified area, you may need to register even if you were previously exempt.

For a complete understanding of how ESI fits into your payroll compliance checklist, including deadlines and filing requirements, refer to our detailed compliance guide.

How ESI and PF Interact

Many business owners ask whether they need both ESI and PF. The answer is: it depends on your employee count and their salaries.

ScenarioPF Applicable?ESI Applicable?
8 employees, all earning ₹18,000/monthNo (below 20)No (below 10/20 threshold)
12 employees in a factory, earning ₹15,000/monthNo (below 20 for PF)Yes (10+ in factory for ESI)
22 employees, all earning ₹35,000/monthYes (20+ for PF)Registered, but no ESI deduction (salary above ₹21,000)
25 employees, 15 earning ₹18,000 and 10 earning ₹30,000Yes (20+)Yes for 15 employees earning below ₹21,000

3. Gratuity: 10 or More Employees

The Payment of Gratuity Act, 1972 applies to establishments employing 10 or more persons on any day in the preceding 12 months.

When Does Gratuity Apply?

Gratuity Applicability FactorDetails
Minimum employees10 on any day in the preceding 12 months
Employee eligibility5 years of continuous service
Calculation formulaLast drawn salary × 15/26 × years of service
Maximum gratuity payable₹20,00,000
“Once covered, always covered”Yes, continues even if employees drop below 10
Applicable toFactories, mines, oilfields, plantations, ports, railway companies, shops, and establishments

Understanding the “Any Day in Preceding 12 Months” Rule

This is where many employers get confused. You do not need to maintain 10 employees throughout the year. If on even a single day in the past 12 months you had 10 or more employees (including temporary and contract workers), the Gratuity Act applies to your establishment.

For example, suppose your retail business in Hyderabad normally has 7 full time employees. During Diwali season (October to November), you hire 4 temporary workers, bringing the total to 11. The Gratuity Act now applies to your establishment, and it continues to apply even after the temporary workers leave.

Gratuity Calculation with Example

For an employee who has worked for 8 years and 7 months (rounds up to 9 years since the service period exceeds 6 months in the last year) with a last drawn monthly salary (basic + DA) of ₹25,000:

Gratuity = ₹25,000 × 15/26 × 9 = ₹1,29,808

ComponentValue
Last drawn salary (basic + DA)₹25,000/month
Service period8 years 7 months (rounded to 9 years)
Calculation₹25,000 × 15 ÷ 26 × 9
Gratuity amount₹1,29,808

For a detailed breakdown of how gratuity works as an employee benefit, including tax implications and special cases, read our comprehensive guide.

Key Point: No Wage Ceiling for Gratuity

Unlike PF and ESI, there is no wage ceiling for gratuity applicability. Every employee who has completed 5 years of continuous service is eligible, regardless of their salary level. The only cap is on the maximum gratuity payable, which is ₹20 lakh.

4. Bonus: 20 or More Employees

The Payment of Bonus Act, 1965 mandates that employers pay a bonus to eligible employees.

When Does the Bonus Act Apply?

Bonus Applicability FactorDetails
Minimum employees20 or more on any day during the accounting year
Employee salary eligibilityUp to ₹21,000/month
Calculation ceiling₹7,000/month or minimum wage (whichever is higher)
Minimum bonus8.33% of salary
Maximum bonus20% of salary
Payment deadlineWithin 8 months of closing the accounting year
“Once covered, always covered”Yes
New establishmentsExempt for first 5 years (with conditions)

Who Gets Bonus and How Much?

Not every employee in a covered establishment is eligible for bonus. The Act specifies these conditions:

ConditionRequirement
Minimum working days30 days in the accounting year
Salary thresholdDrawing up to ₹21,000/month
DisqualificationDismissed for fraud, violent behaviour, or theft

The minimum bonus of 8.33% is payable regardless of whether the company made a profit. This is often referred to as “statutory bonus.” If the company has allocable surplus, it may need to pay up to 20%.

Bonus Calculation Example

For an employee earning ₹18,000 per month:

Since the salary (₹18,000) exceeds the calculation ceiling (₹7,000 or minimum wage, whichever is higher), the bonus is calculated on the ceiling amount.

Assuming the applicable minimum wage is ₹8,500 per month (higher than ₹7,000):

Minimum bonus = ₹8,500 × 12 × 8.33% = ₹8,497 per year

Maximum bonus = ₹8,500 × 12 × 20% = ₹20,400 per year

New Establishment Exemption

If your business is newly established, you get a conditional exemption for the first 5 years. During this period, bonus is payable only in the years where you have made a profit. However, starting from the 6th year, the minimum bonus of 8.33% is mandatory regardless of profitability.

5. Other Labour Laws and Their Thresholds

Beyond the four major laws, several other regulations kick in at specific employee counts. Understanding these is equally important for full compliance.

Maternity Benefit Act, 1961

FactorDetails
Applicability10 or more employees
Benefit duration26 weeks paid leave (first 2 children), 12 weeks (third child onwards)
Eligibility80 days of work in 12 months preceding delivery
Work from homeEmployer may allow after 26 weeks, if nature of work permits
Crèche facilityMandatory for establishments with 50+ employees
Interaction with ESIIf ESI covers the employee, maternity benefit is provided through ESI

Shops and Establishments Act

This is a state level law, and every state has its own version. The key point is that it applies to virtually every business, even with just 1 employee.

StateRegistration ThresholdRegistration Deadline
MaharashtraAll shops and commercial establishmentsWithin 30 days of commencing business
KarnatakaAll shops and establishmentsWithin 30 days
DelhiAll commercial establishmentsWithin 30 days
Tamil NaduAll shops and establishmentsWithin 30 days
GujaratAll shops and establishmentsWithin 30 days of commencing work

This means even a solo founder who hires their first employee needs to register under the Shops and Establishments Act of their state.

Professional Tax

Professional Tax is a state level tax that applies to salaried individuals and professionals. Not all states levy it, and rates vary significantly.

StateMaximum Annual PTMonthly Deduction Range
Maharashtra₹2,500₹175 to ₹300/month
Karnataka₹2,400₹200/month
West Bengal₹2,500₹110 to ₹208/month
Andhra Pradesh₹2,500₹150 to ₹200/month
Telangana₹2,500₹150 to ₹200/month
Tamil Nadu₹2,500₹135 to ₹208/month
Gujarat₹2,500₹200/month
Madhya Pradesh₹2,500₹150 to ₹208/month

States that do not levy Professional Tax include Rajasthan, Haryana, Uttarakhand, Delhi, Himachal Pradesh, Jammu & Kashmir, and several northeastern states.

Labour Welfare Fund (LWF)

LWF is a state level fund, and both the contribution amount and frequency vary by state.

StateEmployee ContributionEmployer ContributionFrequency
Maharashtra₹6/half year₹18/half yearHalf yearly (June & December)
Karnataka₹20/year₹40/yearAnnual (January)
Tamil Nadu₹10/half year₹20/half yearHalf yearly

Contract Labour (Regulation and Abolition) Act, 1970

FactorDetails
Applicability for principal employer20 or more contract workers on any day in the preceding 12 months
Applicability for contractor20 or more workers on any day in the preceding 12 months
RegistrationPrincipal employer must register; contractor must obtain a licence

How to Check Which Laws Apply to Your Business

Follow this step by step process to determine your compliance requirements:

Step 1: Count your total employees correctly

Include every person who works for your business: full time, part time, temporary, contract, and casual workers. Do not exclude anyone based on their designation or salary level when counting for threshold purposes.

Step 2: Identify your establishment type

Determine whether your business is classified as a factory, shop, or commercial establishment. This affects the ESI threshold (10 for factories versus 20 for others).

Step 3: Check the wage and salary levels

Even if your establishment crosses the employee threshold, individual employees may be exempt from certain laws based on their salary. For example, employees earning above ₹21,000 gross are exempt from ESI contribution, and employees earning above ₹21,000 per month are exempt from the Bonus Act.

Step 4: Verify state specific requirements

Check your state’s Shops and Establishments Act, Professional Tax rules, and Labour Welfare Fund requirements. These vary significantly across states. If your business operates in multiple states, you need to comply with each state’s rules separately.

Step 5: Register within the prescribed timeline

LawRegistration Deadline
EPFWithin 1 month of crossing 20 employees
ESIWithin 15 days of becoming applicable
Shops & EstablishmentsWithin 30 days of starting business
Professional TaxWithin 30 days of becoming liable

Penalties for Not Registering on Time

Missing the registration deadline does not make the law inapplicable. You will owe contributions from the date the law became applicable, plus interest and penalties.

LawPenalty for Non Registration
EPFUp to ₹5,000 fine + 1 year imprisonment + 1% per month damages on delayed contributions
ESIUp to ₹5,000 fine + 12% annual interest on delayed contributions
GratuityUp to ₹10,000 fine + 1 year imprisonment + ₹1,000/day for continuing offence
BonusUp to ₹1,000 fine + 6 months imprisonment
Shops & Establishments₹1,000 to ₹25,000 depending on state

For a detailed breakdown of all labour law penalties in India including exact fine amounts, imprisonment terms, and how to avoid them, refer to our complete penalty guide.

Code on Social Security, 2020: What Changes Are Coming

The Code on Social Security, 2020 consolidates 9 existing laws (including the EPF Act, ESI Act, Payment of Gratuity Act, and Payment of Bonus Act) into a single code. Here is what may change when the rules under this code are fully notified:

Current LawCurrent ThresholdExpected Under New Code
EPF20 employeesGovernment may notify a lower threshold
ESI10/20 employeesMay be extended to all establishments with 10+ employees
Gratuity10 employeesMay be reduced to cover gig and platform workers
Bonus20 employeesThreshold likely to remain at 20

The Code also introduces coverage for gig workers, platform workers, and self-employed individuals, which is a significant expansion from the current framework. However, until the rules are fully notified and enforced, the existing thresholds under individual Acts remain applicable.

Keep track of recent changes in Indian payroll laws to stay updated as these transitions happen.

Real Scenario: A 15 Employee Bengaluru Startup

Let us walk through a practical example. Imagine you run a 15 employee SaaS startup in Bengaluru with the following team:

Employee CategoryCountMonthly Salary (Gross)
Senior developers3₹80,000 each
Junior developers4₹35,000 each
Sales team3₹25,000 each
Operations and support3₹18,000 each
Office assistant and housekeeping2₹12,000 each

Here is what applies to you:

LawApplicable?Why?
Shops & Establishments (Karnataka)YesApplies to all establishments
Professional Tax (Karnataka)YesKarnataka levies PT on all salaried employees
Minimum WagesYesMust pay at least Karnataka minimum wage
TDS on SalaryYesFor employees above ₹3,00,000 annual (new regime)
PFNo (but recommended)You have only 15 employees (threshold is 20)
ESIYes, if notified areaFor 5 employees earning below ₹21,000 gross
GratuityYes15 employees (threshold is 10)
BonusNoYou have only 15 employees (threshold is 20)
Maternity BenefitYes15 employees (threshold is 10)
POSH Act (ICC)Yes15 employees (threshold is 10)

Your estimated monthly compliance cost:

ComponentMonthly Cost
Gratuity provision (4.81% of basic for all 15)Approximately ₹18,000 to ₹22,000
ESI employer contribution (3.25% for 5 eligible employees)Approximately ₹3,250
Professional Tax (employer registration)₹2,500/year total
TDS filingTime and effort, no direct cost
Total additional compliance costApproximately ₹23,000 to ₹27,000/month

Once you hire 5 more employees and reach 20, PF and Bonus will also become mandatory, adding approximately ₹50,000 to ₹60,000 per month to your compliance costs (depending on salary levels).

Common Mistakes Businesses Make

Mistake 1: Not Counting Contract Workers

Many businesses believe that contract workers or outsourced staff do not count toward the threshold. This is incorrect. For PF, ESI, and the Contract Labour Act, contract workers employed through a contractor at your premises are counted when determining applicability.

Mistake 2: Thinking Salary Exempts the Establishment

If all your employees earn above ₹21,000 per month, you still need to register for ESI if you meet the employee count threshold. No ESI deductions will be made from their salary, but the registration requirement remains.

Mistake 3: Not Provisioning for Gratuity from Day One

Many small businesses do not set aside gratuity provisions until an employee actually completes 5 years and claims it. This leads to a sudden, large payout that strains cash flow. The correct approach is to provision 4.81% of basic salary every month from the time the Gratuity Act becomes applicable.

Mistake 4: Ignoring the “Once Covered, Always Covered” Rule

As discussed earlier, once PF, Gratuity, or the Bonus Act becomes applicable to your establishment, it continues to apply even if your employee count drops below the threshold. Some businesses try to deregister after reducing staff, but this is not legally permitted and can result in penalties.

Mistake 5: Not Registering for Multiple State Compliances

If your business operates across multiple states, you need separate registrations for Professional Tax, Labour Welfare Fund, and Shops & Establishments in each state. Using HRMS software with multi state compliance can automate this significantly.

How SalaryBox Automates Compliance Tracking

Keeping track of when each law becomes applicable, calculating the right contributions, and filing returns on time is a significant burden for growing businesses. This is especially true when you are crossing thresholds and new laws keep getting triggered.

SalaryBox payroll software automates the entire process:

Automatic PF and ESI calculation: SalaryBox calculates PF contributions at 12% of basic + DA and ESI at 3.25% (employer) and 0.75% (employee) automatically. You do not need to manually compute these for each employee every month. The software handles the ₹15,000 wage ceiling for PF and the ₹21,000 wage ceiling for ESI, applying exemptions where applicable.

Gratuity provisioning: SalaryBox tracks each employee’s service period and calculates gratuity liability in real time. You can see your total gratuity provision at any point and plan your cash flow accordingly.

Bonus computation: When your establishment crosses the 20 employee threshold, SalaryBox automatically identifies eligible employees (those earning up to ₹21,000/month), calculates bonus on the correct ceiling (₹7,000 or minimum wage, whichever is higher), and generates the bonus register.

Professional Tax and TDS: SalaryBox applies the correct Professional Tax slabs based on your state and calculates TDS on salary based on the employee’s declared regime (old or new) and investment declarations.

Compliance alerts: The software alerts you when you are approaching a threshold (for example, when you have 18 employees and are nearing the PF registration trigger) so you can prepare for registration before the deadline hits.

For startups setting up HR for the first time, SalaryBox can be configured in under 24 hours with all applicable compliances pre-set based on your employee count, location, and industry.

Frequently Asked Questions

1. Can an employer with fewer than 20 employees voluntarily register for PF?

Yes. Under Section 1(4) of the EPF Act, an employer and the majority of employees can jointly apply to the Central Provident Fund Commissioner for voluntary coverage. Once granted, the establishment becomes covered under the EPF Act with the same rights and obligations as mandatorily covered establishments. Many startups opt for voluntary registration to offer PF benefits and attract better talent.

2. Do contract workers count toward the employee threshold for PF and ESI?

For PF, the count of 20 employees includes all categories of workers, including contract workers engaged through a contractor. For ESI, the threshold count includes employees directly employed by the establishment. Contract workers are covered under their contractor’s ESI registration. However, the principal employer has the ultimate responsibility to ensure compliance.

3. What happens if an employee’s salary crosses ₹21,000 after ESI registration?

If an employee who was contributing to ESI receives a salary increase that takes their gross above ₹21,000, they continue to receive ESI benefits until the end of the current contribution period (either September or March). From the next contribution period, they become exempt from ESI contribution. The establishment itself remains registered as long as it meets the employee count threshold.

4. Is gratuity applicable to employees who resign before completing 5 years?

Generally, no. An employee must complete 5 years of continuous service to be eligible for gratuity. However, there are exceptions. Gratuity is payable regardless of the service period in the event of death or disablement of the employee. Some court rulings have also held that a service period of 4 years and 240 days can be treated as 5 years for gratuity purposes.

5. Can a startup claim exemption from the Bonus Act for the first 5 years?

Yes, under Section 16 of the Payment of Bonus Act, a new establishment is not required to pay minimum bonus during the first 5 years. However, bonus is payable in any profitable year during this period, calculated based on the allocable surplus. From the 6th year onward, the minimum bonus of 8.33% is mandatory regardless of profitability.

6. How do I determine whether my establishment is a “factory” for ESI purposes?

Under the Factories Act, 1948, a “factory” is a premises where 10 or more workers work (or worked on any day in the preceding 12 months) with the aid of power, or 20 or more workers work without the aid of power, in a manufacturing process. If your establishment meets this definition, the lower ESI threshold of 10 employees applies. Most IT companies, consulting firms, and service businesses are not factories and follow the 20 employee threshold.

7. Does the Maternity Benefit Act apply even if the establishment is covered under ESI?

If an establishment is covered under ESI and the female employee is eligible for ESI benefits (earning up to ₹21,000 gross), the maternity benefit is provided through the ESI scheme. The employer does not need to separately comply with the Maternity Benefit Act for that employee. However, for female employees earning above ₹21,000 (who are not covered under ESI), the employer must provide maternity benefits directly under the Maternity Benefit Act, 1961.

8. What are the penalties for not paying gratuity on time?

Under Section 9 of the Payment of Gratuity Act, the employer must pay gratuity within 30 days of it becoming payable (from the date it becomes due). If the employer does not pay within this period, the employer is liable to pay simple interest at a rate notified by the government (currently 10% per annum) from the date of the employee’s application. Additionally, non-payment can result in a fine of up to ₹10,000, imprisonment of up to 1 year, or both. For a continuing offence, an additional penalty of ₹1,000 per day can be imposed.


Understanding when each labour law becomes applicable is the first step toward building a compliant business.
