Yeah, taxes REALLY suck, last year I ended up paying in almost $60K for taxes, talk about a slap in the face
You can deduct pretty much anything even if you don't have a receipt for the item, if it's something that's logical for your business, you can put it down, that's what my accountant said anyway
You can also deduct a portion of your utilities like you can say that your business is 10% of your home, so you can then deduct 10% of your utilities
