I will just say this about running a legitimate business. Dont!!. Anytime government gets its nose in your business, it will cost you more to stay in business than you can make. Its not just the taxes you have to worry about. As a legit business, are you going to Incorporate, LLC, DBA, what ever, it cost you money just for the paperwork. Doesnt add anything to your bottom line, and it does cost you up front. Then theri is the whole insurance thing, it cost and doesnt add anything to the bottom line. are you going to have employees, more added cost and not just in wages. There is SS taxes, medicare/medicaid, Unemployment taxes, workers comp and general liability. Heaven forbid one of your employees gets hurt on your property, you might end up losing your house. Then there is the accounting, you can buy software, but it aint cheap and you still have to take the time to file the quarterly reports. Dont want to fool with doing it yourself, then you will need a accountant, they cost money too. For a small part time business, it aint worth it to be Legal Legit" You will lose the shirt off your back and the government sets it up where you can lose even more. Never forget, the goveernment will get theirs, whether you get anything or not. Not saying you cant be a legitimate business, as in you sell firewood there fore you are in the firewood business, just keep the government out of it. Trying to write off high equipment cost on a low income business will never work, you simply cant write off more than your business makes. To be "Legal" legitimate, if you are able to write off the equipment as a business expense, and then later if you decide to sale that piece of equipment, you now have to list the sale price as income and pay taxes on that income.
