I incurred expenses last year due to gaining and taking care of my father, he did get social security but I was his legal guardian and was responsible for him can I write off any expenses because of that?
You can't write off expenses per se. You can claim him as a dependent if you provide more than half his total support. If he is your dependent you can claim any medical bills you pay for him.
You can claim a child, relative, friend, fiancé (etc.) as a dependent on your 2018 taxes as long as they meet all of the following requirements :
- You provided more than half of their financial support. More info
- They made less than $4,150 in gross income during 2018 unless they are a qualifying child.
- They live with you or they are related to you. (Your relative must live at your residence all year or be on the list of “relatives who do not live with you” in Publication 501.)
- They are a U.S. citizen, resident alien, national, or a Canadian or Mexican resident.
- They aren't (or won't be) claimed as a dependent by someone else.
- They aren’t filing a joint return with their spouse.
- You are not being claimed as a dependent on someone else's return.
Child of person not required to file a return.
A child isn't the qualifying child of any other taxpayer and so may qualify as your qualifying relative if the child's parent (or other person for whom the child is defined as a qualifying child) isn't required to file an income tax return and either:
- Doesn't file an income tax return, or
- Files a return only to get a refund of income tax withheld or estimated tax paid.
