Form 10A104 example filled out, example: a bakery changes its legal name
Sample Bakery LLC fills out Form 10A104 to update its legal business name. It has one Sales and Use Tax account and changed its name with the Secretary of State first. The picture shows page 1 only, and its names and figures are sample values. Only the name changes, so only Update business name or DBA name is checked, and the cancellation and ownership boxes on later pages stay empty. The form must be signed, so Jane fills the first signature line; the second stays empty. There is no other tax account, DBA name or extension, so those boxes stay empty. Questions 6 and 7 show the Organization Number and the Commonwealth Business Identifier.
