Reasons to File a DBA
If sole proprietors choose to operate a business under a name other than their personal name, they need to register that name with the state, county, city, or town in which the business operates.
If you own a corporation or an LLC, you may choose to operate under a different name than the original legal name of your business. If so, you will need to register this alternate name in the state, county, city, or town where you conduct business.
You will need to register your DBA name prior to opening a business bank account for your alternate name and before advertising or transacting business under another name.
