When they launch sole proprietorships, many people use an assumed name or DBA (doing business as), like Kwik Klean Laundry (catchy name, huh?). But a DBA is optional.

As mentioned, corporations often have substantial tax advantages. An Inc. or LLC after your business name also gives your business added legitimacy and helps it raise or borrow capital. Frankly, sometimes the liability protection is a big deal, and sometimes it’s not. And from an operation standpoint, corporations are always unwieldy.
