Quick Answer
Four categories of foreign income trigger U.S. filing requirements: (1) wages and self-employment income earned abroad; (2) investment income from foreign sources — dividends, interest, capital gains; (3) rental income from foreign real estate; and (4) distributions from foreign trusts, PFICs, and foreign entities. The short version is that U.S. citizens and residents owe tax on worldwide income. In our experience, foreign income triggers not just income tax reporting but also informational returns — FBAR, Form 8938, 5471, 8621, 3520 — each carrying its own penalty regime. IRC §61 defines income broadly; §911 provides the foreign earned income exclusion.1

What about foreign real estate sale?
Capital gain / loss at U.S. rates. Foreign tax credit for foreign tax paid on sale. §121 home sale exclusion can apply to foreign principal residence.
Does treaty relief apply?
Often yes. Bilateral treaties reduce withholding, resolve residency, allocate tax. Form 8833 discloses treaty-based positions.
What if I missed foreign reporting?
Streamlined procedures, delinquent FBAR, voluntary disclosure, or qualified amended return. Path depends on willfulness and amounts. Attorney analysis essential.
Are expats treated differently?
Still U.S. citizens / residents subject to worldwide reporting. FEIE + FTC available. Expatriation (renunciation) under §877A subject to exit tax for covered expatriates.
