Is home care fee deductible when filing taxes {online}? Can an answer be found at irs.gov?

Check with your own CPA on what is deductible in care. The line is sometimes set really really high, I think. I remember this discussion when my brother went into care at Assisted Living.
The IRS.gov site is interesting also, and AARP has online advice, but it is a lot to plough through; I am hoping someone already did the ploughing and can answer this for you, but the resources are there. I found the following interesting from AARP. But again, do ask the question; it is worth the low cost of doing so.

Wishing you the best and welcome.

See page 11 to read about using long term care expenses as medical deductions.

Note that if you don't already itemize and already have enough medical expenses to exceed the minimum, you may not benefit.

Welcome, Marie!
