House Rich, Cash Poor, Low Income Retirement Plan Advice

Instead of charging your daughter rent under the rent a room scheme ask her to contribute to the household expenses while she lives with you. €500 a month seems reasonable.

You should apply for additional needs payments through social welfare where possible.

In terms of getting additional work, if you work at a venue can you try to get additional hours working at the door, cleaning, serving, usher etc. work in a coffee shop in the mornings if your art work is evenings.

Best of luck.
 
Be careful with Revenue on this - they will see the contribution of €500 as income. They may also see them living with her parent as a gift for her. If it was written as an agreement it would be better.
 
Revenue is just not interested in this sort of arrangement.

Anyway, based on the numbers, he still would not have a tax liability.
