The following is from the "What's New" section oc Publication 17. Yes, the EIC is mentioned, but the IRS's wording seems to suggest that everyone who has lived in the US for over half the year should be checking the box because the IRS uses it to check eligibility fior that and other tax benefits. The implication is that it should be checked whether or not you qualify for such benefits.: It does NOT say it shouldn't be checked if you don't qualify for the EIC.
If your main home (and
spouse if filing a joint return) was in
the United States for over half of
2025, check the box on the front of
Form 1040 or 1040-SR. Providing
this information will help the IRS
determine your eligibility for certain
tax benefits, including the earned
income credit.
