Annual Fee

Federal law (Federal Deficit Reduction Act of 2005) requires states to charge families that have never received Temporary Assistance for Needy Families (TANF) a $35 annual application fee if at least $550 is collected annually on their behalf. As of October 1, 2020 the annual $35 fee is assessed for each case in which the family has never received welfare benefits and the custodial party has received $550 or more in support payments during the prior federal fiscal year, (October 1 – September 30). The fee will be collected from the custodial party's next payment(s), until the $35 is paid in full. The fee will be assessed annually in October on cases meeting these criteria.
