Qualified Foster Care payments received by a foster care provider are not taxable income. during the taxable year as qualified foster care payments.

I agree with attorney Tomas and the other attorney that responded. The income received as assistance is not taxable and the children can be claimed as dependents if they would otherwise qualify as described. It would be a good idea for you to have a tax professional prepare this tax return if it is beyond your capabilities as a tax preparer.
