Not necessarily. Whether a new EIN is required depends on the resulting entity and tax structure rather than simply the addition of an owner.

Swyft Filings' EIN service is intended to help customers prepare and submit the information needed for the EIN request. The EIN identifies the business for federal tax and administrative purposes; it does not replace the state formation filing, a business license, or nonprofit tax-exempt recognition. The business should keep its EIN confirmation with its permanent records because banks, payroll providers, tax professionals, and licensing agencies may request it.

Customers should keep the legal business name, entity type, formation details, address, and responsible-party information consistent when requesting an EIN. Changes to an existing business, such as an address or responsible-party update, do not always require a new EIN; the correct treatment depends on the type of change and applicable federal rules.
