Our Experience

Tax and Social Security compliance

Before sending an employee or group of employees overseas to work, it is essential to understand the employer and employee tax and social security implications between two or more countries to ensure compliance prior to the employee commencing work

Arrival & departure tax briefings

Our briefings provide relocation and departure guidance in relation to the employee working overseas and covers residency rules, double taxation agreements, capital gains tax, and, when required, inheritance tax

Payroll set up and processing

Whether employing a single employee or a workforce overseas for a temporary or permanent position, setting up payroll and understanding the processes can be complex. PAYE tax and National Insurance contributions will vary depending on where the employee will be working, their employment type and duration of the assignment

Per diems consulting

Per diems is a daily separate allowance for employees who may incur extra costs when being sent to work outside of their normal jurisdiction. Allocation for items such as lodging or meals are not considered as salary and are non-taxable if they meet certain conditions

Corporate tax & country tax issues, including permanent establishment

Any business expansion generating revenue in another country can be deemed by the local authority as a permanent establishment, meaning this income or VAT may be recoverable by them. Considerations include business location, employee commission, location of contract negotiation and if the employee has a fee generating role. A permanent establishment must be formally registered

Immigration, work permits & visas

Obtaining a work permit or visa to work in or reside in another country is essential to gaining entry. Immigration rules and regulations change frequently and so developing an immigration strategy to ensure ongoing compliance and support of a relocated workforce is key

Employment law & commercial contracts

Employment contracts require consideration of local and foreign immigration, tax and employment laws, and the type of contracts in place will impact the tax obligations of employees and employers
