Claiming ETI exclusion for transactions after 2004
The American Jobs Creation Act of 2004 repealed the general ETI exclusion, but transition rules apply.

Reporting multiple groups of transactions by product line
If you elect grouping (and are not using aggregate reporting), you must report per group on a tabular schedule.
✓ Ensure you check box (2) on line 5c.
Electing to aggregate all transactions onto one schedule
This allows you to file only one Form 8873 while listing multiple aggregated transactions underneath it.
✓ Check box (1)(b) on line 5c.
The grouping redeterminations on Form 8873 are permitted until one year after the later of two dates. These trigger events are: 1. The due date of your timely filed return (including extensions), or 2. Not stated in the official source. Attach this form to your income tax return when filing.

Quick Facts
Downloads
Should I report my general and administrative expenses on line 19?
The source says not to include them on line 19, column (b) — why must they be listed somewhere else?
They are excluded from the direct allocable amount for line 16.
→ Attach a statement listing these amounts with Form 8873.
What is the difference between reporting transactions normally versus using a tabular schedule?
The source mentions both methods — which one should I use?
The choice depends on preference, but if you aggregate, check box (1)(b) of line 5c.
→ Review Instructions for Form 8873 (Rev. 9-2017) -3-.
How do I calculate the final exclusion amount when using marginal costing?
Marginal costing only uses direct production costs — so, what should I enter on line 45?
Enter the greatest of lines 33, 36, 38, or 44 instead of the amount on line 42.
→ Ensure this calculation maximizes the combined exclusion for you and related persons.
Do all related people count toward the $5 million limit?
Yes, all related persons are treated as one taxpayer, meaning only one $5 million limit applies to all of them.

This form helps taxpayers determine how much foreign income should be taken out of their total taxable earnings. The resulting figure shows the portion of worldwide income that is exempt due to extraterritorial rules. Taxpayers attach this completed Form 8873 to their main income tax return for review.
A taxpayer must file IRS Form 8873, which calculates the amount of extraterritorial income excluded from gross income for the tax year.
The form collects information regarding elections (Part I), details about foreign trade income calculations (Part IV), and allows for specialized reporting like marginal costing in Part III. Line 50 specifically tracks potential reductions due to international boycotts.
The instructions do not specify a filing deadline, but the grouping redeterminations are permitted until one year after the later of: 1. The due date of your timely filed return (including extensions), or 2. Not stated in the official source.
The form must be attached to the income tax return it relates to for filing. Specific service center routing is not detailed, but the instructions confirm the need to attach Form 8873 to your tax return.
First, a taxpayer must determine if they are electing to exclude a portion of gross receipts (Line 1) or applying exclusions to certain FSC transactions (Line 2). If grouping is elected, one Form 8873 must be completed with name/ID at the top, and an attached tabular schedule must report all groups. Finally, the form must be signed before sending.
Failure to correctly complete or attach Form 8873 means the calculated amount of extraterritorial income exclusion may be incorrect on the main tax return. The form itself is net of disallowed deductions, so errors affect the final reported taxable income.
They are excluded from the direct allocable amount for line 16. Attach a statement listing these amounts with Form 8873.
