What Is the 330-Day Rule?

The 330-Day Rule refers to the physical presence test used by some taxpayers to qualify for the Foreign Earned Income Exclusion.

To meet the test, a taxpayer generally must be physically present in one or more foreign countries for at least 330 full days during any period of 12 consecutive months.

The rule sounds straightforward, but small travel mistakes can reduce the qualifying day count and jeopardize the exclusion.

Mistake 1: Counting Partial Days

A full day generally means a continuous 24-hour period beginning at midnight. The day you depart the United States and the day you arrive back may not count as full foreign days.

Travelers frequently overcount by including:

  • Departure days
  • Arrival days
  • Days spent partly in the United States
  • Certain days traveling over international waters

A detailed travel calendar is essential.

Mistake 2: Believing You Can Spend 35 Days in the United States

People often describe the rule as allowing 35 U.S. days. That shortcut can be misleading.

A year contains 365 or 366 days, but the qualifying period can be any consecutive 12 months. Travel days, partial days, and time outside a foreign country can prevent certain days from counting. The safer approach is to track 330 qualifying full foreign days rather than relying on a presumed number of U.S. days.

Mistake 3: Using the Calendar Year Automatically

The qualifying 12-month period does not have to run from January 1 through December 31. It can begin on any day.

Choosing the wrong period can cause someone who might otherwise qualify to miss the test. In some situations, the qualifying period overlaps two tax years, and the exclusion is prorated.

Mistake 4: Assuming Any Time Outside the U.S. Counts

The test requires physical presence in a foreign country or countries. Time spent over international waters may not count as presence in a foreign country.

Cruises, offshore work, and extended sea travel should be reviewed carefully.

Mistake 5: Ignoring the Foreign Tax Home Requirement

Meeting the 330-day threshold is not enough by itself. The taxpayer must also have foreign earned income and a tax home in a foreign country.

Someone whose primary business location, family home, and personal connections remain in the United States may face questions about whether the foreign tax home requirement has been met.

Mistake 6: Applying the Exclusion to the Wrong Income

The FEIE generally applies to qualifying earned income, such as wages or self-employment income. It does not generally apply to:

  • Interest
  • Dividends
  • Capital gains
  • Pension payments
  • Rental income that is not earned income
  • Social Security benefits

The source of earned income is generally connected to where the services are performed, not where the employer or bank account is located.

Mistake 7: Failing to Keep Travel Records

Useful documentation can include:

  • Passport stamps
  • Flight confirmations
  • Hotel receipts
  • Immigration records
  • Employment calendars
  • Credit card statements
  • Lease agreements

Do not rely entirely on memory when preparing Form 2555.

Protect Your FEIE Claim

Expats with frequent U.S. travel should calculate qualifying days before booking trips. Expatriate Tax Returns helps Americans abroad review the physical presence test, bona fide residence test, Form 2555, and foreign tax credit alternatives.
