What tax info do I need for my home based business?


I am starting a pool and spa cleaning business. Because it is just starting, it is considered a home based business. I am not going to have any employees so do I need any kind of federal or state tax numbers? I know I will have to pay taxes on the business, so how do I set that up? I have looked online and on the IRS website, but I am hoping someone can explain this in lamens terms. Thanks
