Common misconceptions for Chinese inbound expatriates in the UK

As more Chinese businesses establish operations in the UK and send their employees here, we continue to encounter a number of recurring misconceptions regarding UK tax and social security obligations.

Many of these misconceptions stem from the fact that the UK and China operate under very different tax systems and business mindsets. Concepts that are routine in China may not necessarily apply in the UK, while certain UK requirements can come as a surprise to individuals arriving here for the first time.

Below, we share five of the most common misunderstandings we see amongst Chinese inbound expatriates and explain why early planning remains critical.

1. “My visa determines my UK tax position”

A surprisingly common misconception is that the type of visa an individual holds automatically determines whether UK tax obligations arise.

For example, many Chinese employees visiting the UK on short-term business visas assume that because they are not on a multiple year work visa, and because they may spend fewer than 183 days here, no UK tax obligations can arise.

Unfortunately, the reality is often more complicated.

The first trap relates to directors of UK companies. We frequently come across overseas directors who live predominantly in China and only travel to the UK occasionally. They are often surprised to learn that director’s fees connected with a UK company still need to be processed via payroll and reconciled through self-assessment returns, even where they are not UK tax resident.

The second trap concerns employer compliance. Where (non-director) employees undertake short term business travels to the UK, PAYE obligation starts from day one if they carry out substantive duties. The host employer should consider putting a Short-Term Business Visitor (STBV) Agreement in place with HMRC, which relaxes the relevant reporting requirements where conditions are met.

The third trap is assuming that the UK’s residence rules operate in the same way as China’s. Many Chinese expatriates are familiar with the concept of a 183-day threshold in a calendar year and assume this is the sole determining factor. In reality, UK tax residence is determined under the Statutory Residence Test for a tax year ended 5 April, which considers a range of factors including days spent in the UK, accommodation, work activities and personal connections. It is therefore possible to become UK tax resident under domestic rules even when spending fewer than 183 days in the country.

Expatriates should be careful not to treat immigration and tax as the same thing. A visa governs an individual’s right to enter and work in the UK; it does not necessarily determine their UK tax liabilities.

2. “I am not a UK citizen, so I do not need to report my overseas income”

There is a perception amongst some Chinese expatriates that foreign income remains outside the UK tax net provided they are not British citizens. Arguably, while citizenship does not fully equate to domicile, the historic non-domicile and remittance basis regime simplified the reporting as long as planning was done in advance. However, the introduction of the Foreign Income and Gains (FIG) regime from 6 April 2025 has significantly changed the landscape.

Under the new rules, UK tax residence has become the key starting point. Individuals who become UK tax resident are generally subject to UK taxation on their worldwide income and gains. For newly arriving expatriates, there is some welcome news. Individuals who have been non-UK resident for at least ten consecutive tax years prior to arrival may benefit from a four-year exemption period for qualifying foreign income and gains.

However, one important point is frequently misunderstood. Eligibility for relief does not remove the need for compliance. Individuals still need to report their foreign income and gains and claim the relief on a source by source basis.

The new regime therefore places even greater emphasis on understanding an employee’s personal income position before they arrive in the UK rather than after the first tax return deadline is fast approaching.

3. “UK social security starts from day one”

Given that there is currently no reciprocal social security agreement between the UK and China, many employers automatically assume that UK National Insurance Contributions (NIC) must be paid immediately upon arrival.

In practice, this is not always the case. Chinese expatriates seconded temporarily to the UK can often benefit from a 52-week exemption from UK NIC, provided the relevant conditions are met. Importantly, the exemption generally applies to both the employee and employer.

The financial impact can be significant, particularly for senior executives. For employees, it relieves employee NIC deductions during the exemption period. For employers, it reduces employer NIC costs from arising at the outset of an assignment.

Despite this, we regularly encounter situations where the exemption has been overlooked. This is particularly common amongst smaller UK operations that may only have one or two expatriates and therefore have limited exposure to international assignment issues.

The good news is that where the conditions are met, corrective action may still be possible. However, as with many areas of global mobility, prevention is far easier than remediation.

4. “Salary paid in China does not need to be reported in the UK”

This is perhaps one of the most common misconceptions we encounter.

Many Chinese expatriates continue receiving part of their remuneration through a Chinese payroll while working in the UK. The reasons vary. Some wish to maintain contributions to China’s social insurance programmes, while others simply continue existing payroll arrangements established before the assignment began.

A frequent assumption is that because the salary is paid in China and Chinese individual income tax has been withheld, the income falls outside the scope of UK taxation.

Unfortunately, that is often not the case.

For UK tax residents, employment income is generally taxable on a worldwide basis. The location of the payroll, the bank account into which the salary is paid, or the country that initially deducts tax does not necessarily determine the UK tax treatment.

The introduction of the FIG regime has reinforced this principle. Employers and employees alike should therefore understand the full remuneration package being received worldwide rather than focusing solely on amounts processed through the UK payroll.

That said, planning opportunities may still exist. The Overseas Workday Relief available during the first four years of UK residence can provide valuable relief for qualifying foreign workdays, subject to the relevant conditions and statutory limits. Under the current rules, relief is capped at the lower of £300,000 and 30% of an individual’s qualifying employment income.

The challenge is that such opportunities typically require careful documentation and planning. One pitfall to watch out is the calculation of the upper limit of the relief: apart from salaries paid during the tax year, we need to add any deferred bonuses with the corresponding accrual period.

5. “Personal tax is not particularly important”

Finally, perhaps the biggest misconception is not technical at all. It is cultural.

Historically, personal tax has represented a relatively small proportion of China’s overall fiscal revenues. For many years, tax reporting obligations for employees were limited, and most individuals had little direct interaction with the tax authorities.

Since the 2019 Individual Income Tax reforms, awareness has increased significantly. Annual reconciliation filings have become part of the compliance process, and many taxpayers have become accustomed to completing their obligations through a user-friendly mobile application.

The UK environment is very different.

Income Tax and National Insurance Contributions represent a substantial source of government revenue, and the rules governing internationally mobile individuals are often considerably more complex than many expatriates initially expect. Matters such as residence, overseas income, foreign investment reporting, payroll compliance and cross-border tax reliefs frequently require detailed analysis.

For newly arrived expatriates, this can create a degree of culture shock. Individuals who have never previously needed professional personal tax advice may suddenly find themselves navigating multiple reporting obligations in different jurisdictions.

At the same time, international tax transparency continues to increase. The exchange of information under the Common Reporting Standard (CRS), together with increasingly sophisticated data analytics used by tax authorities, has led to greater scrutiny of cross-border affairs globally.

The positive message is that good planning can still deliver excellent outcomes. The most successful assignments are typically those where tax considerations form part of the conversation before an employee travels, rather than after compliance deadlines have already been missed.

Final thoughts

The UK remains an attractive destination for Chinese businesses expanding internationally. However, assumptions based on domestic experience in China do not always translate effectively into the UK tax system.

Whether the issue concerns residence status, worldwide taxation, social security, split payroll arrangements or personal tax compliance, a small amount of pre-arrival planning can often prevent costly surprises later, and even bring some substantial tax relief. As international mobility continues to evolve following the introduction of the new FIG regime, understanding the rules from the outset has never been more important.
