The Internal Revenue Service (IRS) provides information that will assist programs in determining the gross income of those families with members in the armed forces. Family service staff will find this information beneficial in determining the eligibility of children of military families for enrollment in the Head Start program.
This link will take you to IRS Publication 3 – Armed Forces’ Tax Guide. Go through the index and find the topic of your interest. Major topics of most interest to Head Start programs include: gross income, adjustments to income, income exclusions, and combat pay (among others).
