In the world of finance, we often come across the term "alien" when discussing tax liabilities. An alien is simply a person who is not a citizen of the country they reside in. Unlike some countries, which differentiate between nationals and aliens for tax purposes, most countries base tax liability on factors such as residency and domicile. This means that whether you are a national or an alien, your tax obligations may be determined by where you live and your legal status.
