I work in my home part time. Can I take the home office tax deduction?

Answer 1

You can claim part of the house (home office) rent, part of electricity bill and other expenses as your expenses.

Answer 2

Yes you can .
But your expense should be realistic to what you do otherwise those expense which looks excessive can be disallowed by A.O.
Remember whatever you spent Wholly and Exclusively for your business is allowable.
