The registration of a business name is obligatory whenever an individual, partnership (composed of individuals or corporate bodies, or a combination of both), or any corporate body conducts business under a name other than their true legal names. The primary purpose of registration is to publicly disclose the identities of those individuals, partnerships, or corporate entities that stand behind the business name. See below for a full guide on how to register a business name.
- Sole Trader – Sole Traders, who prefer not to trade under their own legal name, can register a business name with the CRO (Companies Registration Office). have the flexibility to choose any business name, as long as it adheres to the CRO’s business name guidelines. It’s important to note that registering a business name does not equate to registering the entire business; these are separate processes.
- Limited Company – Limited Companies already possess a company name, but they can also register an additional business name or a “trading as (T/A)” name to operate under a different identity. If a Sole Trader decides to transition to a Limited Company and already holds a registered business name, they must deregister the business name associated with the Sole Trader entity and then register it again under the Limited Company.
Sole Traders typically opt for business names to avoid trading under their personal names. Failing to have a distinct business name could hinder the creation of a brand with potential for expansion
Limited Companies commonly adopt business names when their desired company name is unavailable through the CRO (Companies Registration Office). Additionally, companies may register business names for separate divisions when they operate multiple businesses under one entity.
