Q3. How do I get Advance EITC payments?
A3. See if you qualify for Advance EITC payments by completing the five questions on the back of Form W-5, Earned Income Credit Advance Payment Certificate, available here or through your employer.
If you qualify, complete the bottom part of the Form W-5 and give it to your employer. Then, based on your income, your employer adds additional money to your take-home pay in each paycheck.
