If you own a small business, for the love of god pay someone else to do your taxes. It isn’t worth it and it is probably ‘free’ when you factor in the tax money, time and/or headaches they will save you. Plus there is a far less chance you’ll have an audit when the government sees that you are hiring a certified independent organization to deal with that crap.

I made this mistake for a few years before I wised up. Once I went fully paperless and outsourced it was easy.

If you work for someone else, taxes are easy. Do it yourself unless you have complex investments.
