EPF and ESI, filed without spreadsheets.

What 'ECR generation day' looks like at most Indian schools

The 14th of the month. The accountant logs into the EPFO Unified Portal with a UAN-stuck connection, downloads the previous month's wage upload template, opens it in Excel, and starts copying numbers from the locked salary sheet. Twenty-eight rows for twenty-eight teachers. EPF wages, EPS wages, EDLI wages, employer contribution, employee contribution, NCP days, refund of advance. Twenty-eight rows, fourteen columns each, all numerical. One typo in the wage column means the EPFO portal rejects the upload with the unhelpful message: 'File format error. Line 17.'

The accountant fixes line 17, re-uploads. Now line 23 is wrong because the rejection workflow shifted the row numbers. Two more attempts. By 8pm, the file is uploaded, the challan is generated, the school's accountant manually transfers ₹1,84,567 to EPFO via the bank's corporate banking portal, and screenshots the receipt. The same dance happens five days later for ESIC, with a different format and a different portal.

None of this is the school's job. The school ran payroll. EPF and ESI numbers are already inside the locked pay run. Inkwelly's contribution to the world is to remove the manual copy-paste step entirely — the ECR file and the ESIC challan are generated from the same data, on the same day the period is locked. Read the pay periods workflow for how locking works.

How the ECR file is generated

The EPFO Electronic Challan-cum-Return (ECR) is a fixed-width text file with a hash separator (#~#) between fields. Each line represents one employee for one wage month: UAN, name, gross wages, EPF wages, EPS wages, EDLI wages, EPF contribution remitted, EPS contribution remitted, EPF EPS difference remitted, NCP days, refund of advance. The file gets uploaded on epfindia.gov.in, the portal computes the totals, and the challan is generated for online payment.

In Inkwelly, the moment a pay period is locked, the ECR for that period is ready. The accountant opens the pay-period detail page, clicks 'Generate ECR for April 2026', and Inkwelly produces the .txt file pre-validated against the EPFO 2.0 specification. UAN format, length, Aadhaar-UAN linkage status, EPF wage cap (₹15,000 default unless your school has opted for above-ceiling), EPS wage cap (₹15,000), NCP days computation — all enforced before the file is downloaded. If a teacher has a missing UAN or an unlinked Aadhaar, the ECR generation surfaces it as a blocking warning instead of writing a bad file that the EPFO portal will reject silently.

The accountant downloads the .txt file, logs into the EPFO portal, uploads it, and within a minute the portal echoes the same totals back. The challan is generated, copied into Inkwelly automatically (so the next month's accounts entry is one click), and paid via bank corporate banking. Inkwelly tracks the challan number, the payment date, the total contribution, and reconciles it against the locked pay run — every rupee accounted for.

EPF and ESI, both built from the locked pay run

How the ESIC challan works

ESIC — the Employees' State Insurance Corporation — covers employees earning under a gross monthly threshold (currently ₹21,000) for medical care and cash benefits. The school deducts 0.75% of gross wages from the employee, contributes 3.25% from its own account, and remits both via a monthly challan on the ESIC portal by the 15th of the following month.

In Inkwelly, the ESIC monthly contribution is generated alongside the ECR — same locked pay run, different output format. The accountant clicks 'Generate ESIC challan for April 2026'. Inkwelly identifies every employee under the gross threshold, computes the deduction and contribution, generates the .csv format that the ESIC portal accepts, and writes the per-employee IP (Insured Person) numbers and contribution lines. The accountant uploads the file, the portal generates the challan, and the school pays it through the same corporate banking workflow.

Unlike EPFO, ESIC has a strict 'newly insurable' rule — an employee crossing into the threshold from below is added as Insured automatically; one crossing above the threshold mid-period continues to be insured for the rest of the contribution period. Inkwelly tracks both transitions — it does not blindly remove employees from ESIC the month their gross goes above ₹21,000.

What the 15th of the month looks like with Inkwelly

The period is locked on the 28th of the previous month. On the 1st, ECR, ESIC and PT files are auto-generated and a notification goes to the accountant: 'April 2026 statutory pack ready. UAN linkage clean. Total liability ₹1,84,567 EPF + ₹12,800 ESI + ₹6,400 PT.' The accountant downloads the three files, uploads each one to its portal, pays the three challans through the school's corporate banking. Total time on the 1st: under 30 minutes for a 50-staff school. The challan numbers and payment dates flow back into Inkwelly, the employee portal shows each teacher their UAN passbook contribution, and the audit log captures every step.

By the 15th, the deadline that used to consume two days of the accountant's time, the work is already done. The 15th is now just a confirmation date — 'Yes, all challans paid for April. Yes, EPFO and ESIC portals confirm receipt. Yes, no rejections this month.' The accountant moves on to other work. The principal stops worrying about EPFO inquiry notices. Compliance becomes a calendar event instead of a crisis.

Generate your school's ECR for last month — in the demo

Bring last month's locked pay sheet (or a sample), the school's PF code and ESIC code, and we will produce a portal-ready ECR file during the call. No commitment.

Limits, edge cases and small print

For a school with multiple establishments — say, a CBSE branch in Lucknow and an ICSE branch in Kanpur, each with its own PF code — Inkwelly generates a separate ECR per PF code, drawn from the locked pay periods of that branch only. The same applies for ESIC sub-codes. Both EPF and ESI rules can change mid-financial-year (a wage threshold notification, a contribution rate change). When such a change is gazetted, Inkwelly publishes a notice on the school's payroll dashboard with the effective date; from that date onwards, the new rule is applied automatically and the old months remain locked exactly as they were.

For employees who exit during the wage month, the ECR includes their final wage line and an exit date column — EPFO uses this to mark the UAN as 'exited' for that establishment without manual Form 10 filing. For new joiners, EPFO Form 5 is auto-prepared from the joining date in the employee profile. For International Workers (foreign passport holders, applicable mostly for boarding schools with international staff), the IW flag is set and contribution rules apply on the actual basic with no ₹15,000 cap — Inkwelly knows.

ESIC contribution period rules are followed strictly: an employee crossing into the gross threshold mid-period continues to be insured for the rest of that contribution period (April-September or October-March). The school cannot stop ESIC mid-cycle for an individual; Inkwelly does not allow it either. Salary data, statutory data and challan PDFs are stored in India, on Mumbai servers, with seven-year retention to satisfy EPFO inspection windows.
