PF and ESI Compliance for Employers: Contribution Rates, Thresholds, and Due Dates (FY 2026-27)

You hire your 10th employee. Two weeks later, someone mentions ESI. You hire your 20th. Another week later, a friend asks if you registered for PF. By the time you have the conversations, you are already a month late, and the penalties start compounding automatically.

This guide walks through PF and ESI registration, the contribution rates, the deposit cycle, and the penalties if you fall behind.

When Do PF and ESI Become Mandatory?

EPF (Employees' Provident Fund)

EPF registration is required when a business employs 20 or more persons on any day of the preceding financial year. Once you cross the 20-employee mark, you have 15 days to register with the Employees' Provident Fund Organisation (EPFO). Voluntary registration is allowed below 20 employees, typically to offer PF as a benefit.

ESIC (Employees' State Insurance)

ESI is wider in coverage. In most states, any factory or establishment with 10 or more employees drawing wages up to Rs 21,000 a month must register. A few states apply the threshold at 20 employees; Maharashtra and Chandigarh, for instance, kept the 20-employee trigger for a long time before moving to 10 in most cases.

Both counts include full-time, part-time, and contract workers on the rolls. A common trap is excluding interns or contract staff when counting. The law does not permit this; they count toward the threshold.

PF Contribution: The Numbers That Matter

The PF contribution structure has two parts, and both sides pay 12%.

Three points to note:

1. The salary ceiling. The mandatory employer share is calculated on a maximum of Rs 15,000 of basic + DA per month. For a basic of Rs 20,000, the employer can contribute on Rs 15,000 or voluntarily on the full Rs 20,000. The employee can always choose to contribute more.

2. EPS cap of Rs 1,250. Out of the employer's 12%, only 8.33% of salary up to Rs 15,000 (that is Rs 1,250) goes to the pension account. The balance of employer contribution goes into the EPF account.

3. Basic vs gross. PF is calculated on basic + DA, not on gross salary or CTC. Allowances, bonuses, HRA, and overtime are excluded unless they are paid to every employee as a matter of course (which courts have occasionally ruled as deemed basic).

ESI Contribution: Simple but Capped by Wage Ceiling

ESI contribution rates have been stable since July 2019.

ESI is calculated on gross wages, not basic. Overtime is included. The wage ceiling is Rs 21,000 per month (Rs 25,000 for persons with disability). If an employee earns above the ceiling, no ESI applies.

When an employee's wage crosses Rs 21,000 mid-contribution period (April to September or October to March), ESI continues for the remainder of that contribution period. The employee becomes ineligible only from the start of the next contribution period.

Monthly Deposit Cycle

Both PF and ESI follow the same deadline: the 15th of the month following the payroll month.

• Payroll month: April 2026
• Deposit due: by 15 May 2026

The process for PF:

1. Generate the Electronic Challan-cum-Return (ECR) on the EPFO portal.
2. Pay via net banking (SBI, HDFC, ICICI, Axis, and others) or through the EPFO's payment gateway.
3. Download the Transaction-cum-Receipt.

For ESI:

1. Generate the monthly contribution challan on the ESIC portal.
2. Pay via net banking through the ESIC payment gateway.
3. File the monthly contribution return.

Missing either deadline triggers automatic consequences described below.

Penalties for Late Deposit or Non-Compliance

For PF

• Interest: 12% per year for every day of delay under Section 7Q of the EPF Act.
• Damages: Additional levy under Section 14B of the Act, graded by length of delay:

On a Rs 5 lakh monthly PF liability delayed by three months, that is roughly Rs 15,000 in interest plus Rs 12,500 in damages on just that one month.

For ESI

• Interest: 12% per year on the amount of delay.
• Damages: Graded like PF, from 5% to 25% depending on the delay period.
• Continuing default can lead to prosecution under Section 85 of the ESI Act with fines and imprisonment.

Income Tax Side Effect

Under the Income Tax Act, employee contributions deducted from salary are deductible as business expense only if they are deposited by the statutory due date (the 15th). If you deposit late, you lose the deduction under Section 36(1)(va) read with 2(24)(x). The Supreme Court confirmed this position in 2022, and the rule continues under the Income Tax Act 2025.

The employer's own contribution has slightly more leeway and remains deductible if deposited before the ITR due date.

Common Mistakes

1. Registering late after crossing the threshold. The 15-day window is rarely used well. By the time payroll teams realise they are over the threshold, they have missed a quarter.

2. Treating contract or part-time staff as outside the count. Anyone on the rolls drawing wages counts. Courts have been consistent on this.

3. Calculating PF on gross instead of basic. Over-contribution is not refundable, so the employer loses cash flow.

4. Not updating ESI wage eligibility mid-year. When an employee's wage increases past Rs 21,000, ESI stops only at the start of the next contribution period. Stopping immediately is non-compliant.

5. Missing a single month's deposit. The penalty structure makes even a 30-day delay financially painful. For a mid-size SME, that can be a Rs 50,000 to Rs 1 lakh avoidable cost per month.

What to Do if You Are Behind

If you already missed a deposit:

1. Calculate the outstanding amount including interest and damages.
2. Deposit the principal immediately.
3. File the ECR or ESI challan for the missed month.
4. Follow up with EPFO or ESIC for the damages notice (usually issued 60 to 90 days later).
5. Budget for the damages separately and pay before a notice is issued, if possible.

If you have missed multiple months, it is worth engaging a payroll specialist to reconstruct the records and file a consolidated remittance before a labour inspection notice is issued.

Frequently Asked Questions

Do I have to register for PF and ESI if I have only 5 employees?

No. EPF is mandatory only at 20 employees, ESI at 10 in most states. But you can register voluntarily, which some founders do to offer PF as a benefit or to attract talent. Once registered, you commit to the full monthly cycle, so plan accordingly.

If my employees earn above Rs 21,000, do I still deduct ESI?

No. ESI covers only employees earning up to Rs 21,000 per month (Rs 25,000 for persons with disability). Above that, there is no ESI deduction or employer contribution for that employee.

Can I deduct ESI and PF and deposit the total at the end of the quarter to save effort?

No. Both are due by the 15th of the following month. Delayed deposit triggers interest and damages and disallows the expense for income tax purposes. Monthly cadence is the only compliant option.

Is PF calculated on gross salary or basic salary?

Basic + DA. Allowances, HRA, bonuses, and overtime are excluded for the 12% calculation, unless paid to every employee uniformly (in which case courts have ruled they become deemed basic). The cap on mandatory employer contribution is Rs 15,000 of basic + DA.

What is the penalty if I never registered despite crossing the threshold?

Retrospective registration is required. You owe contributions for every month since the threshold was crossed, plus 12% interest plus graded damages (up to 25% per year). EPFO and ESIC can also initiate prosecution. The practical step is to voluntarily regularise before a departmental audit finds it.

The Practical Takeaway

PF and ESI are not complicated in concept, but they are unforgiving on timing. A single missed deposit triggers penalty flows that can quickly exceed the contribution amount itself. For any business growing past 10 or 20 employees, the priority is to:

1. Register within the 15-day window once you cross the threshold.
2. Build the 15th-of-month deposit into the payroll cycle.
3. Reconcile monthly between your HRMS and the EPFO/ESIC portal.

If your payroll is currently handled by a founder or a generalist accountant, moving PF and ESI to a dedicated compliance process usually pays for itself within a quarter by avoiding even one late-deposit notice.

Tax Garden's Compliance and Payroll plan prepares and submits your PF and ESI challans every month, handles registration if you have just crossed the threshold, and reconciles employee-wise statements against your HRMS.
