There are a plethora of tax deductions which you may use to reduce much of your taxable income. One of them is the foreign earned income exclusion.
Foreign Earned Income Exclusion for 2020
For tax year 2020, the maximum exclusion is $107,600 per person. If two individuals are married and both work abroad they can exclude as much as $215,200.
Expat taxes can get complicated and the FEIE is probably the major advantage, but there are others so you will want to consult a qualified accounting professional such as Taxes for Expats or others published by ACA’s comprehensive worldwide guide to tax preparers.
