Founded in 1862, the Internal Revenue Service (IRS) is a U.S. federal agency responsible for the collection of federal taxes and enforcement of tax laws. The IRS is responsible for conducting audits to ensure that taxpayers are claiming or paying what is owed and not cutting corners or hiding assets or income.
In the U.S., there are seven federal income tax rates: 10%, 12%, 22%, 24%, 32%, 35%, and 37%. These rates will remain the same for both 2024 and 2025 because of the Tax Cuts and Jobs Act (TCJA).
The IRS sends notices and letters when it needs to ask a question about a taxpayer's tax return, let them know about a change to their account or request a payment.
Your worldwide income is subject to U.S. income tax the same way as a U.S. citizen. You are a resident of the United States for tax purposes if you meet either the green card test or the substantial presence test for the calendar year.
