InPat And ExPat Payroll: How International Assignments Affect Payroll, Taxes, And Employee Pay
International assignments can create questions about where an employee should be paid, which country has taxing authority, which payroll should process the employee's compensation, how benefits should be handled, and whether a shadow payroll is necessary.
Understanding the interaction between InPat and ExPat payroll is important for payroll professionals who are responsible for employees working across international borders.
What Is An InPat? What Is An ExPat? Defining Inpats And Expats
An inpatriate (aka "InPat") is a person who is from a foreign country and who is temporarily or permanently residing and working in a different country. For example, a citizen from India working in the US is an Inpat.
An expatriate (aka "ExPat") is a person temporarily or permanently residing and working in a country other than that of their citizenship. For example, a US citizen working in Saudi Arabia is and ExPat.
These terms most-commonly refer to professionals or skilled workers sent abroad by their employers to work. Neither should be confused with the term "immigrant', which is a person who comes to a country to take up permanent residence.
How Does InPat And ExPat Payroll Work?
The payroll process for an international assignment generally requires coordination between payroll, HR, benefits, accounting, tax professionals, immigration specialists, and potentially third-party global mobility providers. The payroll process generally involves several important steps.
Identify the Assignment: Determine where the employee normally works, where the employee will work, the expected duration of the assignment, and which entities are involved
Determine Work Authorization: Identify the employee's visa or work authorization requirements and confirm that the employee is authorized to perform the services
Determine Tax Jurisdictions: Identify the countries and jurisdictions that may have taxing or payroll obligations
Review the Compensation: Identify salary, bonuses, allowances, benefits, housing, relocation payments, and other compensation associated with the assignment
Determine Payroll Structure: Determine whether the employee remains on the home-country payroll, moves to the host-country payroll, or requires a split or shadow payroll arrangement
Process Payroll: Calculate compensation, deductions, withholding, and reporting requirements for the applicable jurisdictions
Reconcile Payroll: Compare home-country and host-country payroll information and resolve differences
Complete Reporting: Ensure required payroll and year-end reporting is completed in the applicable jurisdictions
Employers should note that International payroll requires careful coordination because a decision made by HR, immigration, accounting, or global mobility can directly affect payroll processing.
Basic Rules For InPat And ExPat Payroll
Inpat / Expat payroll refers to the payroll responsibilities of providing payroll to individuals whose country of work is different from the country in which they reside.
Inpatriates and expatriates can be subject to different payroll requirements depending on their citizenship, residence, work location, assignment structure, visa status, compensation, and applicable tax laws. International payroll situations can include:
U.S. employees temporarily working in another country
Foreign employees temporarily working in the United States
Employees transferred between countries
Employees working in multiple countries
Employees remaining on a home-country payroll while working abroad
Employees receiving compensation from both home and host countries
Employees requiring a shadow payroll
Employees covered by tax equalization or tax protection programs
Employees working under various types of work visas
The correct payroll treatment depends on the facts of the assignment and the laws and agreements that apply to the employee.
Components Of InPat ExPat Payroll
What Is "Shadow Payroll"?
Shadow payroll is used to report and pay taxes to the US - but not to pay an employee. Essentially, it shows the host-country's reporting and tax withholding obligations.
How Do I Run A Shadow Payroll?
Shadow payroll is commonly established to report and pay an expat employee's host-country taxes while he or she remains on a home-country payroll. It is run by calculating the taxes owed under US law based on the employee's earnings and non-salary benefits.
What Is Tax Equalization For Expatriates? What Does Tax Equalization Mean?
In simple terms, tax equalisation means that the employee pays no more and no less tax while on assignment than they would have paid had they remained in their home country.
Under a tax equalization arrangement, the employee may generally be responsible for a hypothetical tax based on their home-country circumstances while the employer accounts for actual assignment-related tax obligations. Tax equalization can involve:
Hypothetical tax calculations
Actual host-country taxes
Home-country tax obligations
Tax preparation
Tax reimbursements
Tax settlements
Employer-paid taxes
Assignment-related compensation
Payroll professionals should understand how the employer's tax equalization policy affects payroll calculations and coordinate with the tax department or third-party provider responsible for the program.
Tax Protection for ExPat Employees
Tax protection is another approach employers may use for international assignments.
Under a tax protection arrangement, the employee may generally be protected from paying more tax because of the international assignment while retaining the benefit of any tax savings, depending on the employer's specific policy.
Tax protection and tax equalization are not identical concepts, so payroll professionals should understand which policy applies to each assignment. The employer's written policy should establish how taxes, reimbursements, allowances, and other assignment-related payments are handled.
InPat and ExPat Payroll and Work Visas
Work authorization and visa status can be important factors in determining how an international employee should be handled through payroll. Organizations may employ or assign workers under different types of visas or work authorization arrangements. Further, payroll professionals should coordinate with HR and immigration professionals to understand:
The employee's immigration status
The employee's work authorization
The authorized work location
The expected assignment period
Whether the employee can perform services for the employer
Whether payroll withholding requirements apply
Whether additional reporting is required
Whether the employee's status changes during the assignment
Payroll should not independently determine immigration eligibility. Instead, payroll should receive accurate information from the appropriate HR and immigration functions and apply the applicable payroll procedures.
Tax Treaties and International Payroll
Tax treaties can affect how certain income is taxed when an employee works across international borders.
A tax treaty may address issues such as residency, income taxation, withholding, and other cross-border tax matters. Payroll professionals should understand when a tax treaty may be relevant and coordinate with qualified tax professionals when determining whether treaty provisions affect payroll withholding.
Tax treaty provisions can be complex and should not be applied solely based on an employee's citizenship or the name of a visa.
Totalization Agreements and Social Security
Totalization agreements are international agreements designed in part to coordinate Social Security coverage and help address situations in which an employee may otherwise be subject to Social Security taxes in more than one country.
Depending on the countries involved and the employee's circumstances, a totalization agreement may affect which country's Social Security system covers the employee.
Payroll professionals should determine whether a totalization agreement may apply and maintain the appropriate documentation supporting the payroll treatment.
Because Social Security rules for international assignments can be complex, payroll should coordinate with the organization's tax, legal, HR, or global mobility professionals when appropriate.
Foreign Earned Income and ExPat Payroll
U.S. employees working abroad may encounter federal tax rules involving foreign earned income and foreign housing. Certain exclusions or credits may be available to qualifying taxpayers, subject to specific requirements.
Payroll professionals should understand that an employee's eligibility for a personal tax benefit does not necessarily mean that payroll can automatically stop withholding or change payroll treatment. Payroll should coordinate with qualified tax professionals when employees request changes based on foreign earned income, foreign housing, tax treaties, or other individual tax circumstances.
InPat and ExPat Payroll Compensation
International assignments can involve compensation beyond an employee's regular salary. Assignment-related compensation can include:
Base salary
Bonuses
Cost-of-living allowances
Housing allowances
Relocation benefits
Education benefits
Travel allowances
Home leave benefits
Tax reimbursements
Tax equalization payments
Foreign service premiums
Other assignment-related benefits
Payroll professionals need accurate information about assignment compensation because these payments may affect taxable income, payroll withholding, employer taxes, and reporting.
InPat and ExPat Payroll and Employee Benefits
Employee benefits can create additional complexity during an international assignment.
Payroll, HR, and benefits teams may need to determine how health insurance, retirement benefits, life insurance, housing, transportation, and other benefits are treated while an employee is working internationally. Benefits can also affect tax equalization calculations and the employee's taxable compensation.
Payroll should coordinate with the benefits and global mobility teams to identify assignment-related benefits and determine how they should be reflected in payroll.
Home-Country and Host-Country Payroll
An international employee may receive compensation through a home-country payroll, a host-country payroll, or both.
A split payroll arrangement can be used when some compensation is paid in the employee's home country and other compensation is paid in the host country.
Payroll professionals may need to coordinate:
Home-country salary
Host-country salary
Currency conversions
Payroll deductions
Tax withholding
Employer taxes
Benefits
Allowances
Tax equalization
Year-end reporting
Clear communication between the different payroll providers is essential when an employee is paid through multiple payroll systems.
Currency and International Payroll
Currency can create another consideration for international payroll.
An employee may be paid in the currency of the home country, host country, or both depending on the employer's assignment policy and payroll structure.
Currency conversions can affect payroll calculations, tax reporting, employee pay statements, and reconciliation. Payroll professionals should establish a consistent process for obtaining exchange rates and documenting the methodology used for international payroll calculations.
InPat and ExPat Payroll Reporting
International assignments can create payroll reporting obligations in more than one jurisdiction.
Payroll professionals should determine whether the employee requires:
Home-country payroll reporting
Host-country payroll reporting
Shadow payroll reporting
Tax withholding reporting
Social Security reporting
Year-end wage reporting
Assignment-related benefit reporting
Other international payroll reporting
International reporting requirements can vary significantly by country, so employers should coordinate with qualified international tax and payroll professionals when appropriate.
Why HR and Payroll Must Work Together
International assignments require close coordination between HR and payroll.
HR may be responsible for initiating the assignment, while payroll is responsible for implementing the appropriate payroll procedures. Payroll should receive timely information about:
International assignments
Assignment start and end dates
Work locations
Visa and work authorization information
Compensation changes
Assignment allowances
Benefits
Tax equalization arrangements
Tax protection arrangements
Assignment extensions
Employee returns to the home country
Without effective communication, payroll may not have the information necessary to correctly process an international employee.
Note: Most expats do not pay US taxes because of the Foreign Earned Income Exclusion or Foreign Tax Credit benefits. However, expats still need to file taxes annually, even if they do not owe any taxes to the IRS.

Frequently Asked Questions About InPat and ExPat Payroll
What is InPat payroll?
InPat payroll generally refers to payroll for employees from another country who are working in the employer's country or another host country. Inpatriate payroll can involve immigration, tax, payroll, benefits, and reporting considerations.
What is ExPat payroll?
ExPat payroll generally refers to payroll for employees who are working outside their home country. Expatriate payroll can involve home-country and host-country payroll, international taxation, tax equalization, benefits, and reporting.

Shadow payroll is a payroll reporting and tax calculation process that can be used when an employee remains on a home-country payroll while working in another country. It generally does not involve issuing a second paycheck to the employee.
What is tax equalization?
Tax equalization is an employer policy intended to generally keep an employee's tax burden during an international assignment comparable to what the employee would have experienced in their home location, subject to the employer's specific policy.
What is tax protection?
Tax protection is an employer policy that can protect an employee from additional tax resulting from an international assignment while potentially allowing the employee to retain tax savings, depending on the terms of the employer's policy.
Does an international employee need to be paid through two payrolls?
Not necessarily. An employee may remain on a home-country payroll, move to a host-country payroll, or be paid through a split payroll arrangement. A shadow payroll may also be used when additional host-country reporting or withholding is required.
How do work visas affect payroll?

Does an ExPat employee have to pay U.S. taxes?
The answer depends on the employee's circumstances, including tax residency, citizenship, work location, applicable exclusions or credits, and potentially applicable treaties. Payroll professionals should not assume that working outside the United States automatically eliminates U.S. tax obligations.
