Tax equalization

The problem of tax equalisation arises when an individual is working for an international company and starts to work abroad his home country. There are questions of who should pay taxes and how much should he pay. Usually, the individual is receiving a net pay, which is the money he would have received in his home country after taxation. However, the company is obliged to pay taxes for its employee. If they are working in a country with lower taxes, the company takes the savings. On the other hand, if they work in country with higher taxation, the company pays the excess. Either way, the amount received by the employee is same. If the policy only benefits the employee (reducing taxes if working abroad results in higher taxes, but not raising them if working abroad results in lower taxes), then it is referred to as a tax protection policy.

The term "tax equalization" is also used by some American states, such as Nebraska and North Dakota to refer to property appraisal in the context of property tax.


The idea is that an individual´s income stays same.There are some steps how to determine the tax:

Calculate the amount of money paid on taxes in individual´s home country. This sum of money is the hypothetical tax liability.

Reduce the pay of the individual by his/her tax liability.

Add any allowance that is necessary to be paid while he is abroad as a result of an assignment. This is his/her net assignment pay.


Although it may appear easy to calculate your net pay, there are some other difficulties influencing your net pay. For example, if you are using company car in your home country, should you receive some subsidies when you are abroad and unable to use it? Or how is your partner´s income treated?

For whom is the split-year tax system beneficial?

What if an individual leaves the company?

Does your tax equalisation policy discourage individuals from acquiring property abroad?

and many more.


In practice, it is usually about agreement of both sides. Both parties should know on which basis is the tax calculated. After this is calculated, the amount is deducted from individual´s net pay on a regular basis throughout his assignment abroad. It is common, that the company deducts a hypothetical liability at the beginning of the year and then undertakes tax reconciliation at the end of the year.
