Beyond Tariffs: Why the Double Contribution Convention Could Be the UK–India FTA's Biggest Win for Professionals

The UK–India Free Trade Agreement (FTA), which entered into force on 15 July 2026, has largely been discussed in terms of lower tariffs, expanded market access and stronger trade ties. Yet one of its most significant provisions lies beyond the movement of goods. The Double Contribution Convention (DCC), a social security arrangement included in the agreement, has the potential to make temporary cross-border assignments easier and more cost-effective for businesses and professionals alike. While tariff reductions may dominate headlines, the DCC addresses a long-standing challenge faced by companies deploying employees across borders by ensuring eligible workers and their employers do not have to make social security contributions in both countries for the same temporary assignment.

How the Double Contribution Convention Works

The Double Contribution Convention is designed to prevent duplicate social security contributions for eligible employees who are temporarily posted from one country to the other. Instead of paying into both India's and the UK's social security systems at the same time, qualifying employees continue contributing only to their home country's system throughout the approved assignment.

For example, if an Indian company temporarily sends an engineer, consultant or project manager to the UK, the employee and employer continue contributing to India's social security system, such as the Employees' Provident Fund where applicable, instead of also paying UK National Insurance contributions. The same arrangement applies to eligible UK employees temporarily assigned to India.

According to the UK Government, the convention ensures that employees moving between the UK and India, and their employers, are liable to pay social security contributions in only one country at a time. Rather than creating a new benefit, the convention coordinates existing systems to eliminate duplicate payments.

Why the Five-Year Exemption Matters

A key feature of the convention is the duration of the exemption. Eligible employees on temporary assignments can remain covered by their home country's social security system for up to five years. This represents an important development for businesses undertaking medium-term international projects, many of which extend well beyond a few months.

The extended exemption provides greater certainty for employers planning overseas assignments. Companies can deploy specialists, technical experts and project teams without facing duplicate social security obligations during the qualifying period, provided the assignment continues to meet the conditions set out under the agreement.

For professionals, the arrangement also provides continuity in their social security coverage while working abroad on temporary assignments, without requiring parallel contributions in the host country.

Supporting the Movement of Skilled Professionals

Although the FTA is widely associated with trade in goods, the DCC primarily supports trade in services and the movement of skilled professionals. Businesses operating across sectors such as information technology, engineering, consulting, financial services and professional services frequently send employees overseas to deliver projects, support clients and transfer technical expertise.

By reducing the employment costs associated with temporary international postings, the convention supports businesses that rely on cross-border talent mobility. It also benefits professionals whose work increasingly involves international assignments as companies expand their operations across global markets.

Industry bodies including Nasscom and the Federation of Indian Chambers of Commerce and Industry (FICCI) have welcomed the provision, highlighting its potential to support Indian services exports, strengthen talent mobility and improve the competitiveness of businesses operating between India and the UK.

Reducing Costs Without Changing Immigration Rules

One of the convention's most practical advantages is that it removes the additional cost of duplicate social security contributions during eligible temporary assignments. Previously, businesses posting employees overseas could face social security obligations in both the home and host countries, increasing the overall cost of international deployments.

By allowing contributions to continue in only one country, the DCC helps businesses manage employment costs more efficiently while maintaining compliance with social security requirements.

Importantly, the convention does not create any special employment advantage for workers from either country. The UK Government has clarified that the agreement does not make it cheaper to hire Indian workers instead of British workers. The convention simply coordinates where social security contributions are paid during eligible temporary postings.

For employers, this means lower administrative complexity and greater cost predictability when planning international assignments, while professionals continue building their social security record in their home country.

Who Can Benefit?

The DCC applies only to eligible employees on genuine temporary assignments. Workers must remain employed by their home-country employer and continue to be covered under their home country's social security system while working abroad.

The convention does not apply to individuals who permanently relocate or accept employment directly with a local employer in the host country. Similarly, assignments extending beyond the permitted exemption period would no longer qualify for the relief, and local social security rules would then apply.

These eligibility conditions ensure that the convention facilitates temporary business mobility rather than permanent migration.

A Common International Practice

The UK–India Double Contribution Convention follows an approach already adopted by many countries through bilateral social security agreements. Such arrangements are designed to coordinate social security systems for temporary cross-border workers while avoiding duplicate contributions.

The convention does not merge the two countries' social security systems or create new benefits. Instead, it allows eligible employees to remain covered by their home country's existing system during temporary overseas assignments. This provides continuity for workers while simplifying compliance for employers operating internationally.

As businesses increasingly rely on international project teams and specialised expertise, these coordination mechanisms have become an important part of facilitating global trade in services.

What the Convention Does Not Change

While the DCC introduces an important change to social security contributions, it does not alter immigration, employment or visa requirements. Professionals travelling to the UK or India must still meet all applicable immigration rules, obtain the appropriate work visas and satisfy the existing legal requirements for employment.

Nor does the convention provide access to the host country's social security benefits during the exemption period. Eligible workers continue participating in their home country's system rather than building contribution records in the host country.

Understanding these limits is important, as the convention is often misunderstood as a broader labour mobility measure. In reality, it is a targeted mechanism for coordinating social security contributions during temporary international assignments.

The Double Contribution Convention may not attract the same attention as tariff reductions or market access commitments, but its practical impact could be equally significant for businesses that depend on the movement of skilled professionals.

By removing duplicate social security contributions for eligible temporary assignments, the provision reduces costs, simplifies compliance and supports greater workforce mobility between India and the UK. In doing so, it reinforces an important aspect of the UK–India FTA: facilitating not only the movement of goods, but also the movement of talent that increasingly underpins modern trade and investment.
