Non-Resident U.S. Tax: What Non-Residents Need to Know

What Does “Non-Resident” Mean for U.S. Tax Purposes?

In U.S. tax law, non-resident status has nothing to do with where you live emotionally or permanently — it’s a legal classification based on immigration status and physical presence. You are generally considered a non-resident alien for tax purposes if you:

Are not a U.S. citizen

Do not hold a green card

Do not meet the Substantial Presence Test

This distinction matters because non-residents are taxed very differently than U.S. citizens and resident aliens.

How Non-Residents Are Taxed in the United States

Unlike U.S. citizens, non-residents are taxed only on U.S.-source income, not worldwide income. Common types of taxable U.S.-source income include:

  • U.S. employment wages
  • U.S. business income
  • Rental income from U.S. property
  • U.S. dividends, interest, and capital gains (in some cases)
  • Certain U.S. pension or retirement distributions
The tax treatment depends on the type of income, applicable tax treaties, and whether the income is considered:
  • Effectively Connected Income (ECI), or
  • Fixed, Determinable, Annual, or Periodical (FDAP) income

Do Non-Residents Have to File a U.S. Tax Return?

A non-resident must generally file a U.S. tax return if they:

Earned U.S.-source income during the year

Had taxes withheld and want to claim a refund

Are claiming treaty benefits

Conducted business in the U.S.

Most non-residents file Form 1040-NR, not the standard 1040 used by U.S. citizens.
Missing this filing — even unintentionally — can result in:

Lost refunds

Penalties

Future visa or immigration complications

Tax Treaties & Non-Resident Benefits

The U.S. has tax treaties with many countries that can:
However, treaty benefits are not automatic. They must be:
This is where many non-residents go wrong — and where professional guidance matters.

Common Non-Resident Tax Mistakes

Some of the most frequent errors we see include:

Filing the wrong tax form

Paying tax on income that may be treaty-exempt

Failing to file because income was “small”

Assuming withholding equals final tax

Confusing non-resident rules with expat rules

Non-resident taxation is technical, not intuitive.
