How to Calculate PF, ESI and TDS in India (2026 Complete Guide)

Every month, thousands of Indian businesses make the same mistakes — wrong PF deductions, missed ESI filings, incorrect TDS calculations. The result is not just a fine. It is a notice, an audit, or an employee dispute that takes weeks to resolve and damages trust you spent years building.

The problem is not that HR teams are careless. It is that PF, ESI, TDS and PT each have their own rules, thresholds, deadlines and edge cases — and managing all four in a spreadsheet every month, for every employee, is simply not sustainable.

Why Compliance Errors Happen in the First Place

Most payroll errors trace back to three root causes that are entirely predictable — and entirely avoidable with the right system.

1. Wrong salary components in the base calculation

PF is calculated on basic salary and dearness allowance — not gross. ESI is on gross salary up to the threshold. TDS is on taxable income after deductions. If your salary structure mixes these up, every downstream figure is wrong before you even start.

2. Threshold changes not tracked automatically

An employee earning ₹20,500 gross is covered under ESI. Give them a ₹600 increment — they are now at ₹21,100 and exempt from the next contribution period. If no system flags this, you keep deducting ESI from someone who should not be covered. When they find out, you have a dispute, a refund request, and an audit trail problem.

3. Spreadsheets with no validation layer

A copy-paste error, a formula referencing the wrong column, a row accidentally deleted — and thirty employees get incorrect deductions. You will not find out until they call HR, or until the statutory portal rejects the challan. By then, the 15th has passed.

Compliance Deadlines — The Dates That Matter

Missing these dates is where the real cost begins. Wrong calculations are bad. Late filings turn bad into expensive.

How to Calculate PF Correctly

Provident Fund is governed by the Employees' Provident Funds and Miscellaneous Provisions Act, 1952. Here is what you actually need to get right:

The rules most businesses get wrong:

• PF is mandatory if basic salary is ₹15,000 or less — but new employees joining for the first time are covered regardless of salary
• If basic exceeds ₹15,000, the employer can cap PF at ₹15,000 basic — but must apply this consistently
• The EPS cap is hard at ₹15,000 — even if basic is ₹40,000, EPS remains 8.33% of ₹15,000 = ₹1,250
• PF must be deposited by the 15th and the ECR must be filed monthly on the EPFO portal

How to Calculate ESI Correctly

ESI applies to any establishment with 10 or more employees where any employee earns ₹21,000 gross or less per month (₹25,000 for employees with disability).

The nuances that catch businesses out:

• Contribution periods are April–September and October–March. If an employee is covered at the start of a period, they remain covered for the entire six months — even if their salary crosses ₹21,000 mid-period
• ESI is on gross salary, including all allowances, overtime, and bonuses
• New employees must be registered with ESIC within 10 days of joining

How to Calculate TDS on Salary

TDS on salary under Section 192 is the most complex — it depends on each employee's total estimated annual income, the tax regime they have chosen, and any declared deductions.

New Tax Regime (default from FY 2024-25)

Standard deduction of ₹75,000 is available under the new regime — meaning an employee earning up to ₹12,75,000 per annum effectively pays zero tax after the rebate under Section 87A.

Professional Tax — The One Most Businesses Forget

Professional Tax is levied by state governments. Not all states have it, every state that does has different slabs — and it is easy to miss when you expand to a new state.

Manual Calculation vs Automation — What It Actually Costs

Here is what manual payroll compliance costs a 50-person Indian business every month:

That is 144–216 hours per year — the equivalent of one full month of an HR executive's working time, spent entirely on calculations that software should be doing. One statutory notice handled externally can cost ₹15,000–₹50,000 in CA fees alone.
