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