Tax Deductible Home Office

[David Nacco]

Could someone who is tax savvy help me out here? I am considering building a home office, and by building a home office I mean actually building a completely separate structure from the living area behind my house. Would I be able to write off the construction and furnishing costs of building this office on taxes as a business expense? What about the costs of pulling any necessary permits? I know I could just get a good sized shed and convert that into an office space but I figured if I can write off something nice that looks and feels more like an actual office then why not do that
