Entities usually register with the Secretary of State or state corporations division. An EIN is a free federal tax ID from IRS.gov. A registered agent receives official notices. Keep formation, license, tax and contract records organized, and update every listing together when details change. Rules vary by state and city, so confirm requirements with the official agency.
Where do I register my business?
Entities are usually registered with your Secretary of State or state division of corporations. Local registration and business tax may also apply. Use the official state website rather than third-party filing services unless you want their help; official sites list exact fees and forms.
What documents should I retain?
Keep formation documents, EIN confirmation, licenses and permits, leases, insurance policies, contracts, bank statements, tax filings and receipts in an organized, backed-up location. Keep digital copies in a backed-up folder and originals in a safe place. Name files consistently so you can find them quickly when a bank or agency asks.
What is an EIN?
An EIN (employer identification number) is a federal tax ID issued by the IRS. Many businesses need one for hiring, certain structures, or opening a business bank account. Sole proprietors without employees may use their SSN for some purposes, but many still get an EIN to keep their SSN off forms and accounts.
Where is the official EIN application?
Apply directly on IRS.gov; the IRS does not charge for an EIN. Be cautious of sites that charge for the same service. Have your business details ready; the online application is usually completed in one session and the EIN is issued at the end.
What is a registered agent?
A registered agent is the person or company designated to receive official legal notices for an entity. Many states require one for LLCs and corporations. Some owners act as their own registered agent; others hire a service, especially if they want privacy or are often away from the address.
How do I update business contact information?
Update your state registry, IRS records if applicable, licenses, bank, insurance, Google Business Profile, website, social profiles and directories, using the same format everywhere. Make a checklist of every place your contact details appear and update them in one session, then check search results a few weeks later.
