## What Is Expatriate Tax Equalisation?

Expatriate Tax Equalisation is an employer compensation policy under which an internationally assigned employee bears the home-country tax cost while the employer pays actual taxes.

*Also known as: Tax Equalization, Tax Equalisation Policy.*

## How Expatriate Tax Equalisation works

Expatriate Tax Equalisation starts when an employer sends a worker on an international assignment and agrees, in an assignment letter, to deduct a hypothetical home-country tax from pay while the employer meets the actual host-country and home-country taxes on the employee's employment income. Because tax paid by the employer is itself generally taxable earnings, payroll grosses up the net pay; HMRC guidance for tax equalised arrangements in the United Kingdom describes this grossing up and a settlement after the self-assessment return. Policy terms vary by employer and decide which income, such as personal investment income, falls outside equalisation.

## Expatriate Tax Equalisation vs Tax Protection

Unlike tax protection, under which an employer only reimburses the excess of host-country tax over home-country tax, Expatriate Tax Equalisation also lets the employer keep any saving when host-country tax is lower.

## Example

Illustrative example: An employee from Country A is assigned to Country B for two years. Payroll withholds a hypothetical Country A tax from salary, the employer pays the higher Country B income tax, and the grossed-up tax payment is reported as additional taxable earnings in Country B.

## Common misconception

**Myth:** An equalised employee has no personal tax filing obligations during the assignment.

**Reality:** Expatriate Tax Equalisation shifts the cost of tax to the employer, but the employee generally remains the taxpayer and may still file returns in the host and home countries.

## Frequently asked questions

### What is hypothetical tax?

Hypothetical tax, under Expatriate Tax Equalisation, is an estimate of the home-country tax the employee would have paid without the assignment, deducted from pay while the employer covers the actual taxes.

### What is the difference between tax equalisation and tax protection?

Expatriate Tax Equalisation keeps the employee's tax cost at the home-country level in both directions, whereas tax protection only reimburses host-country tax exceeding the home-country amount.
