Tax Residency Calculator Usa

Determining your tax residency in the United States is crucial for understanding your tax obligations. This calculator helps you assess your tax residency status based on your physical presence, intent to remain, and other factors.

What is Tax Residency?

Tax residency refers to the legal status of a person as a resident of a particular country for tax purposes. In the United States, tax residency determines whether you are subject to US federal income tax, state income tax, and other tax obligations.

Under US tax law, you may be considered a resident for tax purposes if you meet certain criteria, such as maintaining a permanent home in the US, having a US citizenship or green card, or spending a significant amount of time in the country.

How to Determine Your Tax Residency

Several factors determine your tax residency status in the US:

Physical presence: The amount of time you spend in the US
Intent to remain: Whether you plan to stay in the US long-term
Domicile: Where you consider your permanent home
Visa status: Your immigration status
Tax treaties: Agreements between the US and other countries

The IRS uses a "substantial presence test" to determine residency. If you meet the test, you're considered a US tax resident for the entire year.

US Tax Residency Rules

The US has specific rules for determining tax residency:

Substantial Presence Test

You're a US tax resident if you meet either of these tests:

You're present in the US for at least 31 days during the current year and 183 days during the 3-year period that includes the current year and the 2 years immediately before it.
You're a resident of any state for any period during the current year.

Non-residents are subject to US tax on their worldwide income, while residents must file a US tax return and pay US taxes on their worldwide income.
