Quick Facts
Downloads
Do I need to file Schedule H if I am a partner in a partnership with deductions allocated to ECI?
Yes, any foreign corporation that is a partner in a partnership that has deductions allocated to ECI under Regulations section 1.861-8 must complete Schedule H and attach it to its Form 1120-F (Instructions p.1).
Do I have to adjust my home office interest expense on line 2?
No, do not make adjustments on line 2 to reflect book-to-tax adjustments for any home office interest expense included on line 1a; this adjustment is reported on line 4 instead (Instructions p.2).
How are third-party and interbranch interest expenses handled?
These expenses included on line 29 are adjusted separately on lines 32a and 32b, not on line 30 (Instructions p.5).
If I report business profits under a U.S. income tax treaty, do I still need to file Schedule H?
No, if the corporation files Form 1120-F using treaty rules that apply OECD Transfer Pricing Guidelines, Schedule H is generally not required (Instructions p.1).
What currency should I use for Part I of Schedule H?
You may complete Part I in U.S. dollars or in the foreign corporation's functional currency; if using a functional currency other than U.S. dollars, specify it in the heading (Instructions p.2).
When calculating exchange rates for lines 15 and 17, how should rounding be handled?
The exchange rate must be rounded to at least five places, but round to more than five places if failure to do so would materially distort the exchange rate or the equivalent amount of U.S. dollars (Instructions p.3).

The form collects details on home office deductions and reports the allocation and apportionment of expenses recorded on books used for the U.S. trade or business. Specific sections include Part I, which determines the reporting currency, and Part IV, which uses Schedule L books to report expense allocations.
First, the filer must determine if Part I will be completed in U.S. dollars or a functional currency. Deductions related to home office operations are entered on lines such as 1a, while allocations of expenses to ECI and non-ECI are reported using Part IV.
The instructions do not specify penalties for incorrect filing; they focus on proper required reporting procedures and ensuring that results reported on Schedule H are included on Form 1120-F, Section II, line 26.
