Re: tax year start/end? if you're a sole proprietor, you'd probably want to stick with december, since that's the year your personal tax year ends too. and as a sole proprietor, the two are tied together.
you file taxes normally but also file a schedule C and various other forms, depending on what you have going on. depending on how much profit you expect, you might want to start paying quarterly estimated tax on your business earnings.
best things is to find an accountant to give you advice and set things up properly from the start. |
