    How to Measure Worldwide Income

    Worldwide income is measured by adding all of your taxable income from your domestic and foreign earned income. The income may include your wages, business income, and income from investments. You will need to report all of your worldwide income on your tax return. 

    How Is Worldwide Income Distributed?

    Worldwide income is distributed via an aggregation of the taxpayer’s income, both domestic and foreign. However, there are some exceptions for any U.S. citizen that is living abroad. 

    A percentage of the income earned by Americans who have worked overseas may be excluded from taxes or eligible for a foreign tax credit by the Internal Revenue Service. The tax credit is available to American citizens and resident aliens who pay income taxes levied by another nation or American territory. The tax credit can lower your tax obligation in the United States and is designed to prevent double taxation on the same income. 

    Lawyers and accountants who specialize in international taxation are frequently used by multinational corporations and individuals to reduce or otherwise shelter their global tax bills. Delaying tax payments through these tax planning techniques can result in compound growth and significant increases in capital bases.

    How Is Tax Calculated on Worldwide Income?

    All of a taxpayer’s international income, whether taxable or not, must be disclosed to the IRS.

    The IRS may levy taxes on funds given to US citizens or permanent residents in the form of salary, payments to independent contractors, pensions, rent, royalties, and investment income. The tax for worldwide income is calculated in the same way their domestic income is calculated. 

    Worldwide income can be split into three separate classifications:

    • Earned income: Including wages and salaries, tips, bonuses, commissions, and professional fees.
    • Unearned income: Including dividends, interest, winnings from gambling, capital gains, and pensions.

    Variable income: Including rents, royalties, business profits, and scholarships and fellowships.
