On 17 June 2026, the U.K. and the Republic of India agreed that the Double Contribution Convention (the “DCC”) will come into force, alongside the broader Free Trade Agreement.1

      Please see the GMS Flash Alert (1 June 2026) for initial coverage of the DCC.


      WHY THIS MATTERS

      The DCC is expected to ease administrative and financial pressures for employers and internationally mobile employees by clarifying which country’s social security system applies during temporary postings. 


      Key Highlights

      Transitional Rules

      The DCC will not apply to individuals who are already on assignment on the day the agreement enters into force. U.K. employees who are already working on assignment in India will not be entitled to a Certificate of Coverage and will become subject to Indian social security legislation, even if they are paying U.K. social security by virtue of the U.K. domestic 52-week liability rule. In the same manner, Indian employees who are already on assignment in the U.K. will become subject to U.K. social security legislation, even if they are within the first 52 weeks of the assignment and exempt from paying U.K. social security contributions under U.K. domestic law.

      Detached Workers

      • Certificate of coverage: Employees going on assignment from the U.K. to India and from India to the U.K. on or after 15 July 2026 can remain subject to the home country social security legislation and exempt from paying social security contributions in the host country. This is providing that the period of work abroad will not exceed 60 months (as opposed to the 36 months initially announced) and that certain eligibility conditions are met.

      • Certificate of coverage eligibility: The U.K. and India have agreed that to benefit from a Certificate of Coverage and remain insured in the home country social security scheme, employees must have been subject to the legislation of the home country for at least 30 days prior to their assignment in the host country or  employer and employee contributions must have been paid in respect of the employment for the calendar month before the start of the assignment.

      • Assignments from third countries: An individual who is sent by their employer on assignment to the other state from a third country can still be entitled to a Certificate of Coverage, as long as they are paying social security contributions in their home country immediately before the start of the assignment.

      • Personal choice: An individual who personally decides to work temporarily in the other country can still be entitled to a Certificate of Coverage, as long as their employer agrees to this. There is no requirement for a formal assignment to be in place.

      • Cooling-off period: If an individual completes an assignment and is subsequently sent to work in the host country again, they are not entitled to a Certificate of Coverage until a period of six months has elapsed. If their previous assignment was shorter than six months, the “cooling-off period” will be the same length of time as the previous period of work in the host country.

      • Exceptions: The competent authorities of both states may agree on exceptions for particular individuals or categories of individuals. In exceptional situations, this could allow employees to remain within their home‑country system for 36 months, providing that a request for an exception is made, wherever possible, in advance.

      Voluntary Contributions

      • Individuals who are subject to the legislation of the U.K. or India are not entitled to pay voluntary social security contributions under the legislation of the other state for the same period. 
         
      • Individuals who are already on assignment from the U.K. to India on the date the agreement comes into force, who will become subject to the Indian social security legislation, will not be entitled to pay voluntary U.K. social security contributions.

      Split Social Security Liability

      As the DCC does not contain specific rules for individuals working simultaneously or alternately in both countries, HMRC clarifies that individuals employed in both countries may be liable to pay social security contributions in both the U.K. and India, regarding earnings from their respective employments in the U.K. and India.

      Entry into Force

      The DCC will take effect from 15 July 2026 after both countries exchange written confirmation that domestic legal requirements have been fulfilled. 


      KPMG INSIGHTS

      The DCC will eliminate historical double social security contribution liabilities. Employers should review their current and planned assignments between the U.K. and India to ascertain the implications of the DCC, ensure they are compliant with the rules and structure assignments efficiently.

      If assignees and/or their programme managers have any questions or concerns about the scope of the update, its application and potential impacts, and appropriate next steps, they should consult with their qualified professional or a member of the GMS team with KPMG in the U.K. (see the Contacts section).
