What Is tax equalization?

Tax equalization is a policy where employees working abroad pay the same taxes they pay in their home country. This policy helps companies and employees avoid tax implications across jurisdictions when employees accept international assignments. Tax equalization requires the employer to take responsibility for all taxes on employment income in the home and host countries.

The employee pays a “hypothetical tax” based on what they would have paid in their main country of residence.
Tax equalization is a part of expat compensation packages, including housing allowances, cost of living adjustments, and education benefits.

How does tax equalization work?

1. The company determines the employee’s tax liability based on their home country’s tax rate, also called the home tax.
2. The company calculates the tax liability based on the host country’s tax rate or host tax.
3. The employee pays the taxes they would have paid if they remained in their home country. If the host country has a higher tax rate, the company covers the difference.
   Employees may also be offered tax protection, where the company pays any additional taxes resulting from the assignment in the host country. This allows employees to focus on their work without worrying about taxes.
4. At the end of the assignment, employers settle the tax liabilities. The company may conduct a “settlement” to reconcile what the employee has paid against what they would have paid under the home country tax rate.

Steps for Gross-Up Calculation:

Find the grossed-up amount with the following calculations:

Annual salary x (1 – home country’s tax rate) = employee’s net pay in home country
Employee’s net pay in home country / (1 – host country’s tax rate) = employee gross salary

How to execute tax equalization

• Calculate the employee’s hypothetical tax based on home country rates and withhold the amount from their paychecks
• Process tax payments in both home and host countries
• Maintain shadow payroll reporting in the host country, but keep the employee on the home country’s payroll
• Review and adjust tax equalization calculations every quarter to factor in income changes or life events
• Conduct year-end reconciliation to compare hypothetical tax withholdings against actual tax liability
• Make up the difference by collecting additional tax from the employee or giving them a refund

The goals of tax equalization

1. Tax neutrality: ensure employees do not gain or lose money to taxes when accepting an international assignment.
2. Assure compliance: Protect the company’s finances, operations, and reputation by complying with tax laws across all jurisdictions where the company operates.
3. Cost management: tax equalization minimizes unnecessary expenses or administrative burdens.

Benefits of implementing tax equalization for expat employees

• Protection from double taxation
• Financial consistency as expats’ net pay remains the same
• Employees can move locations without needing to worry about tax implications
• High employee retention
• Increased mobility

Challenges of implementing tax equalization

• International tax regulations vary between countries and are subject to change making it difficult to maintain compliance across several jurisdictions
• Tax equalization requires a sophisticated payroll solution and coordination between multiple parties, including tax providers and payroll teams
• Calculation errors can increase when dealing with multiple tax jurisdictions and currencies, potentially leading to significant financial and compliance issues
• Many expat employees feel confused about their take-home pay and tax obligations
• Regulatory updates in either home or host countries can require immediate policy changes.

Is tax equalization different from tax protection?

Tax equalization and tax protection policies both protect international employees from extra tax burdens. Under tax equalization, employers are responsible for compliance. They pay the host and home country taxes and deduct the employee’s taxes from their taxable income at the end of the pay period.

Under tax protection, the employee must maintain tax compliance. They pay the host country’s taxes, and the employer reimburses them for all extra costs at the end of the pay period. If their tax due is lower than their hypothetical tax, employers don’t need to reimburse them.
