Form 1120-F for foreign corporations with US branch activity

Branch profits tax, effectively connected income and treaty relief for a foreign company trading in the US through a branch rather than a US subsidiary.

Foreign corporationFiling deadline
With a US office04/15
Without a US office06/15
Extension (Form 7004)+6 months
Branch profits tax30%, treaty may reduce

Filing more than 18 months after the original due date can mean losing the right to deductions and credits against that income entirely.

Where this bites

The deadline turns on a determination, not a date on a calendar

Whether you file by April or June depends on a factual question — do you maintain an office or place of business in the US — not on where the company was incorporated.

Deadline depends on “office or place of business”That determination, not your entity’s home country, sets whether you file by 04/15 or 06/15
An extension doesn’t move the payment dateForm 7004 extends the filing deadline; any tax due is still owed on the original date
Branch profits tax is separate from income taxA further 30% levy on repatriated branch earnings, unless a treaty reduces it
A protective return can preserve deductionsFiled even when you believe no US return is owed, in case that position is later challenged
