How Tax Residence Works for Immigrants

Tax residence and immigration status are separate tests. Many countries treat a person as tax resident after spending 183 days there in a year or keeping their main home or centre of vital interests there, and residents are generally taxed on worldwide income. Double taxation treaties decide which country has the primary right to tax a given income, and the other country usually grants a credit or an exemption.

The United States is an exception: it taxes citizens and green card holders on worldwide income wherever they live, through Form 1040, with relief available via the Foreign Earned Income Exclusion and the Foreign Tax Credit. People with foreign financial accounts above a reporting threshold also file an FBAR with FinCEN.

Taxes also surface in immigration decisions. On Form N-400 applicants answer questions about unfiled returns and unpaid tax, and USCIS weighs those answers when judging good moral character, with IRS tax transcripts as the usual proof of compliance. In Europe, renewals of residence permits such as digital nomad or startup permits often depend on filed tax returns and paid social security contributions.
