If my mom lives with me and pays me to be her caregiver do I have to pay taxes?

Does your mom pay her share of costs to live in the house?

This would be tax free to you and legal for her.

I would encourage you to see a certified elder law attorney (www.nelf.org) and get this set up legally, whichever way you go you don't want to find out that you have disqualified mom for public assistance by the choices made. An attorney can help you do this in a way that protects everyone from future consequences.

Orrrr.....the money you get from her is a gift and you don't have to pay taxes on it.

Yes and you need a caregiver agreement and a rental agreement. Mom becomes your employer with the responsibility of tax witholding, payments to social security, etc. This will protect both of you.

Mom will keep medicaid eligibility. You will not be hiding income from IRS.

Consult with an elder law attorney to set everything up properly.
