Social Security Agreements and the Certificate of Coverage, explained
Published 13 Aug 2026 · Reviewed 13 Aug 2026
What an SSA does
A Social Security Agreement (SSA) is a treaty between India and another country. It stops the same person’s social-security contributions being demanded twice — once in the home country, once in India — for the same period of work.
Without an SSA, an inbound assignee to India would normally fall under EPF Para 83 as an International Worker. This means contributing 12% employee plus 12% employer on their full global package, uncapped. An SSA gives a route out of that, for a limited period, through a document called the Certificate of Coverage.
India has roughly 20 SSAs in force. Coverage terms vary by agreement, so the exact detachment period and process should always be checked against the specific treaty text, not assumed from a general rule.
The Certificate of Coverage, and how it works
A Certificate of Coverage (CoC) is issued by the home-country social-security authority, before the assignment begins or shortly after. It certifies that the assignee continues paying social security in the home country for the agreed detachment period.
Holding a valid CoC makes the assignee an “excluded employee” under Para 83. Indian EPF does not apply to them for as long as the CoC covers. This is the cleanest and, per the current knowledge base, the only clean exit from Indian PF for an inbound International Worker.
Timing matters. The CoC should be obtained before the assignment start date, not after. An employer without a CoC in hand at the start of the assignment should budget for full Indian PF contributions from day one. Para 83 coverage has no built-in short-stay grace period.
Detachment periods
The recently concluded UK–India Double Contributions Convention (DCC) was signed 10 February 2026 and came into force 15 July 2026. It exempts UK assignees from Indian social security for up to 36 months under its detachment provision. Before 15 July 2026, this exemption was not yet operative — the effective date matters, not just the signature date.
What happens with non-SSA countries
If the assignee’s home country has no SSA with India, there is no CoC route. Coverage under Para 83 is unavoidable: 12% employee plus 12% employer PF contributions, on the full global package, with no wage ceiling.
This is not a small gap. India has roughly 20 SSA partners, out of many more countries that send assignees inbound each year. An employer should check the SSA list as a first step for every new assignment, not assume one exists just because a large economy is involved.
Withdrawal is also more restricted. A non-SSA-country International Worker can generally only make a final PF withdrawal at age 58, after leaving covered employment. This does not happen on exit from India, and not on resignation alone. This is a materially different position from a domestic employee’s more flexible withdrawal rules. It should be built into the assignment cost projection from the start, not discovered at repatriation.
Illustrative example: an assignee from a non-SSA country on a ₹1.2 crore global package has no exemption route available. The employer should plan for roughly ₹14.4 lakh a year in employer PF contribution alone, on top of the employee’s matching share, for the full duration of the assignment. There is no early-withdrawal relief for the assignee at exit.
Documentation checklist
- Confirm whether an SSA exists between India and the assignee’s home country, before the assignment is finalised.
- Request the CoC from the home-country authority early. It should be in hand before the assignment start date, not applied for retroactively.
- Record the detachment period the CoC covers, and calendar the expiry date — coverage that runs past the CoC’s stated period reverts the assignee to full Para 83 status.
- Keep the CoC on file for EPFO inspection. Section 7A enforcement inquiries specifically test whether a claimed exclusion is backed by a valid, current CoC.
- Where no SSA exists, document the full-contribution plan as part of assignment cost approval, so the ₹1.5 crore-scale numbers above are not a surprise at year-end reconciliation.
- At exit, check age and withdrawal rules that apply to the assignee’s specific coverage status — SSA-country terms differ from the general age-58 rule for non-SSA IWs.

General guidance, not legal advice — confirm the specific SSA text and CoC process with India counsel or your payroll provider before relying on it.
