if you plan on working alone sole pro. is gonna be what you want. if you don't have employees, or charge sales tax you can file taxes under your social security number.
it all has to do with paper work, and the fine details. the less the better. i took a class at a college, and learned about some of this.
every area is different on lisences, check it out with local govt.
NEVER work without insurance!!! if you wanna start out on the completely wrong foot, that would be the ticket. i pay about $400 a year for $500,000.00 liability. even if you decide you don't wanna mow anymore, you could cancel the insurance.
You can begin your business venture as a sole proprietor if necessary, and incorporate later as your business expands,take on employees etc.The best advice is as mentioned above, talk to a CPA, or tax professional. Most defiantly look into what the local, county, and state license requirements are.Purchaseing Liability insurance is a given.
Definitely hire an accountant and discuss your game plan with him/her. An accountant will usually give you a 1st consultation for free. They will get you on the right track. In my opinion it would be a very bad move to do business without Gen Liab. it is not that expensive and can end up saving your rear "IF".
