Welcome to Just Answers! Thank you for giving me the opportunity to assist you! I will do my best to help!
There are actually two separate issues here. The first one is someone giving you money. That action is not taxable to you, but it could be reportable, and perhaps taxable, to the person who gave you the money.
The medical bills are the second issue. You can deduct as an itemized deduction any qualified medical expenses that exceed 7.5% of your adjusted gross income (AGI). These expenses include things like doctor bills, dentist bills, medication, hospitals, home health care, etc. They also include health insurance if the premiums are paid with after tax dollars (i.e, not pretax through a work plan).
If you have, for example, $65,000 of wage income, and another $1,000 in dividends and interest, your AGI is $66,000. In order to have any deductible medical expenses, your medical bills would have to exceed $4,950. So if you had $8,200 of medical expenses, you could deduct $3,250 ($8,200 - $4,950 = $3,250).
I hope this answers your questions! If you have any more, including any regarding particular medical costs (my wife has stage 4 cancer, so I have learned more about medical expenses than I ever wanted to in my life!), please feel free to ask away!
Again, thanks! Enjoy your Sunday!
