Every month, your HR and finance teams face the same quiet pressure: the Employees' State Insurance Corporation (ESIC) portal deadline is approaching, the contribution challan needs to be filed, and a stack of Form 6 or Form 6A data entries sits waiting. Miss the 15th of the month for deposit or the half-yearly return window, and the interest clock starts ticking at 2 percent per month. For businesses running across multiple states or with contractor workforce, ESI compliance becomes a parallel full-time job on top of an already stretched payroll cycle. ESI Return Filing under the Employees' State Insurance Act, 1948 (Act 34 of 1948) is not optional once your establishment crosses the mandatory threshold. It is a legal obligation backed by penal provisions under Section 85 of the Act, which prescribes penalties for evasion or non-payment. The ESIC, operating under the Ministry of Labour and Employment, Government of India, runs the compliance ecosystem through the esic.in portal. KAMRIT Financial Services LLP manages your complete ESI compliance cycle: from initial Code Number registration to monthly challan filing, half-yearly Form 6 and 6A return preparation, and employee registration in Form 1. We handle portal submissions, reconcile your contribution records, and ensure your acknowledgement is in hand before the deadline. You stay compliant; your team stays free to run operations.
What is ESI Return Filing in India 2026?
ESI Return Filing is the periodic submission of contribution and enrollment data to the Employees' State Insurance Corporation under the Employees' State Insurance Act, 1948 (ESI Act). The Act creates a social security fund financed by contributions from covered employers and their employees, used to provide medical, sickness, maternity, and disability benefits. The filing ecosystem operates through two primary return forms. Form 6 (filed under Rule 26 of the ESI Central Rules, 1950) is the half-yearly return submitted by factories and establishments covered under the Act. Form 6A is filed by principal employers operating establishments with one or more contractors, to declare the employee headcount and contribution details for the reporting period ending 31st December and 30th June each year. Form 7 is filed monthly by factories for challan-cum-return purposes. The compliance cycle has two distinct streams: monthly deposit of contributions through a digital challan on the ESIC portal (due by the 15th of the following month), and half-yearly return filing (due by 31st May for the period ending 31st December, and 30th November for the period ending 30th June). The ESIC portal at esic.gov.in serves as the single window for both streams. Failure to file on time attracts interest at 2 percent per month under Section 85 of the ESI Act, and persistent non-compliance can invite prosecution under Section 84. Every employer who has obtained a 17-digit ESI Code Number must file returns even during months when no contribution is due, by submitting a NIL return.
Who needs this
ESI coverage is triggered automatically once an establishment crosses the defined threshold. Understanding whether your business falls within the mandatory coverage net is the first compliance step.
- Factories and establishments where 10 or more persons are employed on any day in a month, earning wages up to the notified ceiling (currently Rs 26,000 per month for the wage ceiling exemption threshold under Section 96 of the ESI Act, as amended).
- Non-seasonal factories and establishments in states where the ESI scheme has been extended by the state government through a notification under Section 1(5) of the Act. Not all states have extended coverage to non-factory establishments; check state-specific coverage notifications.
- Seasonal factories, where the threshold remains 10 or more persons, but the seasonal operation provision under Section 1(5) applies differently to calculation of man-days.
- Private educational institutions and private hospitals with 10 or more employees, if the state government has extended the scheme to these categories by a specific notification.
- Restaurants, hotels, and cinema halls classified as establishments in states that have notified these under the Act, even if they are not factories under the Factories Act, 1948.
- Principal employers in contract labour arrangements, where the principal employer must file Form 6A declaring all contractor employees who are covered under the ESI Act.
- Establishments that cross the 10-employee threshold mid-year are required to obtain ESI registration within 15 days of crossing the threshold under Rule 3 of the ESI (General) Regulations, 1950.
- Establishments already registered but which fall below the threshold due to reduction in workforce must continue filing returns unless formally deregistered by ESIC through a cancellation order under Regulation 10-B.
- New employees earning up to Rs 26,000 per month who join after initial registration must be declared within 15 days of joining through Form 1 submission.
- Establishments already covered under the Employees' Compensation Act, 1923 (formerly Workmen's Compensation Act) may still be required to file ESI returns if the employee count and wage ceiling criteria are independently met.
Documents required
ESI compliance requires a layered document stack that bridges your statutory registrations, payroll records, and portal-level declarations. Missing even one document can halt the filing process.
- ESI Registration Certificate (Form 1A issued by ESIC) or the 17-digit Employer Code Number allotment letter from the regional ESIC office, confirming your establishment is registered under Section 2A of the ESI Act, 1948.
- PAN Card and TAN (TDS) of the establishment, required for digital challan generation and linking of ESIC portal account with income tax records.
- Shops and Establishments Registration Certificate issued by the respective state Labour Department, as ESIC cross-references this during Code Number verification.
- Form 1 declarations submitted for each eligible employee at the time of initial registration, containing name, father's name, address, date of birth, and family particulars.
- Monthly salary register or payroll data for the entire contribution period, showing gross wages, deductions, and days worked for each employee. This determines the contribution base.
- Bank statements or NEFT/RTGS confirmation for the previous two contribution challans, used to reconcile deposit records against portal records.
- Previous ESI challan receipts (last three months) if your filing involves correction or revision of filed returns.
- List of all contractor establishments and the number of contractor employees deployed at your site during the half-year, required for Form 6A preparation by principal employers.
- Cancelled cheque or bank account details of the designated ESIC contribution account, to verify the remitting bank account matches the ESIC-registered account.
- Muster roll or attendance register extract for the contribution period, used to verify employee count and days worked for man-day calculations.
- GSTIN and IEC (Import Export Code) if the establishment is registered under the GST regime, as ESIC may cross-verify with GSTN data during audit.
- Factory license under the Factories Act, 1948 (Form 2) if the establishment is a factory classified under that Act, required for establishments with manufacturing operations.
How KAMRIT runs it, step by step
The ESI return filing cycle operates on a defined monthly and half-yearly cadence. KAMRIT maps each stage to the actual steps required on the ESIC portal, with internal checklists and reconciliation checkpoints at every handoff.
- Establishment Assessment and Code Verification. KAMRIT begins by verifying your existing ESI Code Number against the ESIC portal records. We check whether your establishment is active, whether all previously registered employees are correctly listed in the IP database, and whether your employer contribution account is in good standing with no pending demand notices or interest liabilities. Any discrepancies found at this stage are resolved before the filing window opens. This step also confirms which forms are required for the current filing cycle: Form 7 for monthly challan, Form 6 for standard half-yearly return, or Form 6A if you are a principal employer with contractor employees. This assessment takes 1 working day from receipt of all documents.
- Document Compilation and Payroll Reconciliation. We collect the monthly salary registers, attendance data, and bank statements for the contribution period. KAMRIT reconciles the total wages paid against the ESI contribution deposited for the period to ensure the challan amount matches the payroll data. Any short deposits or excess deductions are flagged and corrected before filing. The team also compiles the employee addition and deletion list, which captures new joinees and resigned employees during the period. This reconciliation stage typically takes 2 working days depending on the size of the employee database.
- Employee Data Validation on ESIC Portal. Before filing the return, KAMRIT validates the IP (Insured Person) database on the ESIC portal for each employee. We verify that Form 1 declarations have been submitted for all current employees, that there are no duplicate entries, and that the IP numbers assigned to employees match their current employment records. For employees whose details have changed (name after marriage, address change, etc.), we prepare the necessary modification data. This step is critical because errors in the IP database will cause the return to be rejected during scrutiny.
- Challan Generation and Monthly Deposit Support. For monthly filing, KAMRIT prepares and submits the contribution challan through the ESIC employer portal. The challan amount is calculated as 3.25 percent of the total wages paid to covered employees by the employer (under Section 39(1) of the ESI Act) plus 0.75 percent deducted from employee wages (under Section 39(2)). The combined challan is remitted via NEFT/RTGS through the linked bank account. We confirm the UTR number and reconcile it against the portal receipt. The monthly challan must reach the ESIC account on or before the 15th of the following month; KAMRIT files at least 5 working days before the deadline to allow for bank processing time.
- Form 6 / Form 6A Preparation and Portal Submission. KAMRIT prepares the half-yearly return in the prescribed form. For factories and standalone establishments, Form 6 is prepared with the total employee count, wage bill, contribution details, and the employee-wise muster for the period. For principal employers, Form 6A is prepared listing all contractor establishments and the count of contractor employees deployed. The return is submitted through the employer login on esic.gov.in. The system generates a filing acknowledgement number upon successful submission, which is shared with the client as confirmation of receipt.
- Return Scrutiny and Acknowledgement Confirmation. After submission, KAMRIT monitors the ESIC portal for any scrutiny flags, return discrepancy notices, or non-receipt intimation from the regional ESIC office. The ESI return is subject to scrutiny under the Scrutiny Manual of ESIC, and an acceptance or rejection intimation is issued within 30 to 60 working days. We track this window and respond to any deficiency memos on behalf of the employer within the prescribed response period, typically 15 days. Once the return is accepted without objection, we provide the final filing summary and archive the acknowledgement for your records.
- Interest Clearance and Compliance Certificate Support. If any interest liability has accrued due to delayed deposit or under-payment during the period, KAMRIT prepares the interest calculation under Section 85 of the ESI Act (2 percent per month or part thereof on the amount of arrears from the date on which the contribution became payable) and submits the interest payment challan separately through the portal. We also assist in obtaining a No-Demand or Compliance Certificate from the regional ESIC office, which is often required during statutory audits, bank loans, and government contract bidding. This stage typically requires an additional 10 to 15 working days for ESIC processing.
Timeline
From the day all documents are submitted in order, KAMRIT completes the preparation and portal submission for a standard monthly challan filing within 3 to 5 working days, with the acknowledgement typically generated on the same day of submission. The monthly deposit reaches the ESIC account within 1 to 2 working days of the NEFT/RTGS instruction, subject to bank processing. For the half-yearly return (Form 6 or Form 6A), KAMRIT requires 5 to 7 working days for preparation and submission. ESIC's acknowledgement is generated instantly on the portal, but the return undergoes a formal scrutiny process that takes 30 to 60 working days depending on the regional ESIC office's workload. If any deficiency memo is issued during scrutiny, the total timeline extends to 60 to 90 working days. If the establishment is applying for a fresh ESI Code Number (for a newly covered employer), the process runs in parallel: ESIC typically allot the Code Number within 7 to 15 working days of receiving Form 1, though state-level offices with backlog can take 30 to 45 working days. Post-code allotment, the first return must be filed for the month in which the code was obtained. Government holidays, regional ESIC office closures, and portal maintenance windows can add 5 to 10 working days to any stage. The employer has no control over the regulator-controlled scrutiny phase, but KAMRIT controls the filing date and ensures no avoidable delays occur on the service side.
How our pricing compares
KAMRIT Financial Services LLP offers ESI Return Filing support starting at Rs 899 per month for a single-establishment employer with up to 20 employees. This covers monthly challan filing, portal submission, and half-yearly Form 6 preparation and submission. For establishments with 20 to 100 employees, the monthly retainer is priced between Rs 1,499 and Rs 2,499 depending on complexity. Principal employers with contractor workforces filing Form 6A are quoted separately, typically in the range of Rs 1,999 to Rs 4,999 per half-yearly cycle, given the additional complexity of consolidating contractor data. IndiaFilings charges between Rs 1,500 and Rs 2,999 per filing cycle for ESI return services, with additional charges for Form 6A and NIL return filings. Vakilsearch prices ESI compliance services at Rs 1,999 per cycle for standard establishments, with a separate annual maintenance plan at Rs 6,000 to Rs 9,000. ClearTax charges approximately Rs 2,500 per filing for monthly challan services and Rs 3,500 for half-yearly returns, though their pricing is primarily bundled within broader payroll or compliance plans. LegalRaasta offers basic ESI filing support at Rs 999 to Rs 1,800 per month but is known for limited post-filing support if scrutiny notices are issued. KAMRIT's pricing is competitive against all four named competitors. Our Rs 899 starting rate is lower than IndiaFilings and ClearTax for equivalent services. The value differentiation lies in three specifics: KAMRIT includes interest calculation and correction filing at no extra charge within the retainer, covers post-scrutiny follow-up with the ESIC office as part of the service scope, and assigns a dedicated relationship manager rather than a ticket-based support model. Government fees, which include the 3.25 percent employer contribution and 0.75 percent employee contribution remitted to ESIC, are pass-through charges borne by the employer and are excluded from KAMRIT's service fees across all packages.
Common mistakes KAMRIT avoids
Even experienced finance teams unfamiliar with ESI-specific rules make errors that trigger interest liabilities, scrutiny notices, or compliance gaps. Most are avoidable with structured preparation.
- Missing the monthly deposit deadline of the 15th of the following month, triggering simple interest at 2 percent per month under Section 85 of the ESI Act on the entire outstanding contribution amount from the date it became payable.
- Incorrectly calculating the wage ceiling and including employees earning above Rs 26,000 per month in the contribution base, or conversely excluding eligible employees earning below the ceiling, both of which distort the challan amount and invite scrutiny.
- Failing to declare contractor employees in Form 6A when the establishment is a principal employer, resulting in an under-declaration of the covered employee pool and potential penal action under Section 84 of the Act.
- Not filing NIL returns during months when no ESI contribution was payable due to zero employee count, which is a separate filing obligation; failing to file NIL returns creates a compliance default on the ESIC portal.
- Missing the half-yearly filing deadlines of 31st May and 30th November for Form 6 and Form 6A respectively, which run parallel to the monthly challan cycle and are often overlooked by teams focused only on deposit compliance.
- Incorrect IP number assignment on the portal, where employee Form 1 data is mismatched with the IP database, causing the contribution credit to be unattributed and creating a discrepancy in the employee's benefit entitlement records.
- Not registering new employees in Form 1 within the 15-day deadline from the date of joining, which creates a gap in social security coverage for the employee and a non-compliance entry for the employer on the ESIC portal.
- Filing under the wrong state code on the ESIC portal when the establishment operates across multiple states, each of which has a separate ESIC regional office and account code, resulting in cross-state reconciliation failures and demand notices.
