Quick Facts

Do I need to fill both qualification boxes?
Both the bona fide residence and physical presence test boxes appear on the form, leading users to think both are required.
→ Select only the box that reflects the test you expect to meet.
What if I don’t know my exact housing cost?
The form asks for an estimated amount, which some filers mistake for an exact figure.
→ Use a reasonable estimate based on anticipated expenses and document the basis.
Is a signature required if I submit electronically?
The form’s certification language mentions a signature, causing uncertainty for electronic filing.
→ Provide a physical signature or a printed electronic signature as required by the employer.
Can I use this form for a part‑year foreign assignment?
The form references a 12‑month period but also allows a partial year with start and end dates, which can be confusing.
→ Enter the actual start and end dates of the qualifying period if it is less than a full year.
Do I need to attach Form 2555 with Form 673?
Some filers think the two forms must be submitted together to the employer.
→ Only Form 673 goes to the employer; Form 2555 is attached to the tax return (Form 1040 or 1040‑SR).
What if my employer says they will not honor the exemption?
The form states employers may disregard it if they doubt qualification, leading to uncertainty.
→ Verify with the employer that they have received the form and understand the exemption request.

Form 673 tells your employer not to withhold U.S. income tax on wages you earn while working outside the United States if you expect to qualify for the foreign earned income exclusion. You also estimate any foreign housing expenses so the employer knows how much can be excluded.
U.S. citizens who expect to qualify for the foreign earned income exclusion must file Form 673 with their employer.
The form collects the employee’s name, SSN, qualification choice (bona fide residence or physical‑presence test) in Part I, estimated housing costs on lines 1‑9 in Part II, and a signed certification in Part III.
Give the completed Form 673 to your U.S. employer.
Enter your first name, initial, last name, and Social Security number at the top. In Part I, check the box that reflects the test you expect to meet for the foreign earned income exclusion. Complete Part II by listing rent, utilities, insurance, and other qualified housing expenses on lines 1‑6, sum them on line 7, enter the base housing amount on line 8, and compute the difference on line 9. Sign and date Part III, then hand the form to your employer.
Providing false information can lead to perjury penalties and may cause the employer to continue withholding tax on the wages.
