The real question on this all Hallow's Eve is:
Can I get a tax deduction for the candy I give out?
If you are an individual, no, not at your front door. If you are a business, yes, if you link it to advertising/ordinary and reasonable business marketing type expenses.
However, you can also just be lazy at home, and send your leftovers to our troops. Apparently this DOES count as a tax write off for an individual. Learn how here.
Whatever you do, stay safe out there. And just for fun, send some well wishes to this poor little girl.
