Taxes in Illinois as a dependent
My son made $2500 in 2022 where $120 in taxes were deducted. He is a dependent and a resident of Florida. $20 were deducted as federal taxes and $100 as Illinois taxes. When I started his tax return as a dependent, the $20 seems to get refunded but not the $100 on the Illinois tax return. Is there any way he can claim those $100 in Illinois taxes?
