A bit of clarification about my dad's situation;
He's retired state worker in California. He has Kaiser Senior Advantage (Medicare HMO). He has a pension of about $3,000, SS of about $1200 and soon a VA pension of $1,800. He is 85 years old with Alzheimers. He's totally dependent and according to the tax accountant, 100% of his income is used for medical, so he pays no income taxes. All his monthly income just barely covers his full time care at a facility. He has almost zero savings of any kind, less than $10,000 anyways. (Long story short, a couple of his grand daughters bilked him out of his savings including the sale of his home when he had to go into the memory care assisted living facility). If his income is going to be subject to federal income tax, he won't have enough to cover the expenses for where he lives now. It's been hard enough on us all to even have to send him to any place, but to have to move him would just seem cruel as he can't/wouldn't understand. My brother and I will probably make up the difference if Dad even lives long enough to see any tax changes that affect medical deductions. But even if he doesn't live that long, it doesn't mean there aren't a boat-load of other seniors who are in the same situation; can afford to pay their own way with the tax write offs for medical but would need to make major changes if taxed.
One thing his tax accountant told me is that I can probably write him off as a dependent on my taxes if I do have to cover his overages. Yes, he files as a single adult, but I have durable power of atty for his medical and financial.
Thanks for the replies. I appreciate the feedback. Other than his memory issues, he has peripheral neuropathy, arthritis, high blood pressure, high cholesterol and is treated for mild depression. He has outlived his two wives, neither of which he can tell you their names. He forgets who my wife is and while he knows I'm his son, he does forget my name occasionally. It's hard to see him degenerate this way, but it adds insult to injury if his medical condition is no longer a tax write off. I sure hope our representatives reconsider those with advanced age or severe disabilities when they make their law.
