You may not qualify for Earned Income Tax Credit (EITC) with an AGI of $8,034 due to insufficient earned income, which includes wages, salaries, tips, and self-employment earnings but excludes Social Security, unemployment, and investment income.
Other top reasons include filing status (Married Filing Separately disqualifies you) and exceeding the $11,000 investment income limit. If you are under 25 or over 64 without a qualifying child or were claimed as a dependent, you are also ineligible.
