Several things can disqualify you from receiving EITC, including:
Earning more than $59,187.
Having investment income over $10,300.
Filing a Form 2555 with the IRS, which is related to foreign income.
There may be other disqualifying factors. If you’re not sure whether you qualify, it’s best to consult with a tax professional. The IRS has a Qualification Assistant tool to help determine your eligibility.
