Can I get paid as a caregiver for my mother?

She can pay you.
Have a contract drawn up.
Spell out exactly what you will do.
How much she is to pay you. Set it up so that taxes are taken out so it does not effect your work history and it does not effect the possibility of her applying for Medicaid if necessary.
I would also have a time on the contract where the contract is to be renewed. This way if your mom needs more care you can ask for an increase in pay if you are doing more work. If she has not declined the contract can remain as is until the next review.
I would also indicate at what point you can no longer care for her and she would have to go to a Memory Care Facility if you can not care for her at home or on your own. (you can include that if the desire to remain at home she also has to pay for other caregivers as well as any adaptation that might be needed)
Strongly suggest that you consult an Eldercare Attorney for this as well as any other paperwork that needs to be taken care of.

Your mother can pay you, yes. Just make sure you have a caregiver agreement drawn up that outlines what your duties are and how much you will be paid. This will ensure that if she needs to go in to long term care on medicaid, there won’t be any issues with the 5 year look back.
