Perhaps you've made the extraordinary commitment of moving Mom or Dad (or both) into your house to live with you so that you could provide continuous care and keep them out of a nursing home. If you made that commitment this year and have stuck with it this long then you are to be commended; it's a tremendous sacrifice and chances are that it turned out to be at least ten times harder than you thought it was going to be.
Anyway, the purpose of this post is to let you know about a significant tax benefit that you should take advantage of. One caregiver client recently commented that his experience with taking care of Dad at home is proof-positive that "what goes around comes around". In other words, when he was a child he depended on Dad to take care of him, and now he's doing the same for Dad.
Just remember that the IRS rewards you when someone depends on you, so make sure you find out if you are eligible for a "dependency exemption" on your income tax return for taking care of Mom/Dad. Also, if you have shelled out money for their medical expenses, then it may be possible to write those expenses off as well.
If you have an accountant you should call him/her to talk about the details. Or if you live in the Hartford County area and you don't have an accountant but would like a referral please let me know.
