Buying group health insurance in India requires four categories of documents: company KYC, employee census, financial and tax documents, and past claims history (for renewals or insurer switches). Submitting these in a single, complete bundle reduces issuance time from 14 days to 3 to 7 days. Here's the full checklist.
Category 1: Company KYC Documents
The insurer needs to verify the existence and legitimacy of the policyholder organisation. Required documents:
- PAN card of the company — original document or self-attested copy
- Certificate of Incorporation issued by the Registrar of Companies
- GST registration certificate (GSTIN) — required for invoicing and ITC determination under CGST Section 17(5)(b)
- Memorandum of Association (MOA) and Articles of Association (AOA) — for first-time policy issuance with most insurers
- Board resolution authorising the purchase of group health insurance, signed by authorised directors
- Authorised signatory ID and address proof — typically the CFO, HR head, or company secretary; Aadhaar, PAN, or passport plus proof of address
- Latest annual report or audited financial statements — for large enterprises and high-premium policies
Category 2: Employee Census File
The most operationally important document. The census is a structured file with one row per employee, listing:
- Employee name (or employee ID for anonymised data)
- Date of birth — drives age-based premium calculation
- Gender — affects maternity rider premium
- Date of joining the company
- Designation or grade — used for industry and role risk classification
- City of residence — drives geographic premium loading
- Spouse details (name, date of birth, gender) if covered
- Children details (names, dates of birth, gender) if covered
- Parent details (names, dates of birth, gender, relationship — parent vs parent-in-law) if covered
Insurers and insurtech platforms typically provide a template. Submitting in the template format speeds up processing; manual entry from unstructured data adds 1 to 2 days.
Category 3: Financial and Tax Documents
- Bank cancelled cheque or recent bank statement — confirms the account from which premium is being paid
- GST registration certificate — required for invoicing with proper GSTIN, particularly relevant for understanding Section 17(5)(b) ITC blocking on group health insurance
- Latest audited financial statements — required for large enterprise policies (typically above ₹50 lakh premium) and for credit assessment
- TAN (if applicable) — for tax deduction at source on payments above defined thresholds
Category 4: Past Claims History (Renewals and Switches)
For employers renewing with the same insurer or switching to a new insurer, additional documents help with accurate renewal pricing:
- Claim register from the previous policy year — showing claims filed, settled, and pending
- Loss ratio data — claims paid as a percentage of premium received
- Premium history for the previous 2 to 3 years
- Existing policy document — for portability under IRDAI rules
- TPA correspondence if relevant to ongoing claims
Optional Documents That Strengthen the Application
- HR contact details and benefits platform integration requirements
- Specific TPA preferences if incumbent relationships exist
- Renewal date alignment with existing policies for unified administration
- Past employee health check data for wellness program design
Common Documentation Mistakes
- Submitting employee census with missing dates of birth, dependant gender, or spouse details
- Mismatched authorised signatory — the person signing the application differs from the board-resolution-authorised signatory
- Missing GSTIN, which complicates invoicing
- Providing photocopies when originals or self-attested copies are required
- Not disclosing past claims history when renewing or switching insurers
- Missing board resolution for first-time policy purchase
Timeline Impact of Document Completeness
- Complete documentation upfront: policy issuance in 3 to 7 working days
- Documents in instalments: issuance extends to 10 to 14 working days
- Missing critical documents (employee census, KYC): issuance may extend beyond 14 days, particularly if the insurer queries each gap separately
How to Organise Documentation
- Use a single shared folder (Google Drive, Dropbox) with the insurer or platform for all documents
- Use the insurer's employee census template — don't submit Excel files in a custom format
- Have the authorised signatory's ID, photograph, and address proof ready in digital format upfront
- Pre-verify GSTIN to ensure no errors
- If renewing, collate the previous year's claim register and loss ratio data before requesting quotes
Document Storage After Policy Issuance
Once the policy is issued, retain digital copies of all submitted documents plus:
- The final policy document (master policy)
- The premium invoice and GST invoice
- The board resolution
- Records of employee enrolments and endorsements
These are needed for renewals, claim disputes, audits, and tax filings (Section 37(1) deduction proof).
Frequently Asked Questions
What's the most commonly missed document when buying group health insurance?
The complete employee census in the insurer's template format. Most delays stem from missing dates of birth, dependant details, or geographic information rather than KYC documentation.
Do I need a board resolution to buy group health insurance?
Most insurers require a board resolution authorising the purchase, particularly for first-time policy issuance. Renewal usually requires only a continuation authorisation.
Is the GST registration certificate mandatory?
Yes, for invoicing purposes. The GSTIN is also relevant under CGST Section 17(5)(b), which blocks Input Tax Credit on group health insurance for most employers (limited exceptions for mandatory-by-law insurance).
What past claims data do I need to share when switching insurers?
Claim register from the previous policy year, loss ratio data, and premium history for the past 2 to 3 years. This data drives accurate renewal pricing from the new insurer.
