Earned Income Tax Credit errors can delay your refund or result in your EITC claim being denied. Watch out for these common errors when claiming EITC:

• Claiming a child who does not meet all of the qualifying child tests: relationship, age, residency and joint return. Read more about the qualifying child rules here.
• Social Security number or last name mismatches.
• Filing as single or head of household when married.
• Over or under reporting of income.
