I'm a sole proprietorship - how can I change my business address?

Yes, I have no clue what I%26#039;m talking about. I hate business. I filed a DBA a few years ago so I could buy supplies wholesale. But now I%26#039;ve moved, AND want to change the business name. And I have no clue how to do it. Can somebody help me?!|||You just need to file a change of address at the license office, as well as the post office. You will also need to note the new address on you income tax forms.
