Wife is in assisted living and chronically ill with Alzheimer's. I plan to deduct monthly cost, but what is the documentation required from a doctor? Is it an IRS form?

No documentation is required to deduct those expenses on your return. If audited you may be asked for documentation from a physician.

Thanks for the reply. Do you know if the documentation is something that is supposed to already be in place, or can a doctor provide the document if/when I get audited?
