Business registration decisions
How to Register a Business
Start with the operator, then connect the name, tax accounts and operating permissions to the business you will run.
To register a business, work through five decisions: choose the operator and structure, establish the legal and trading names, complete any entity filing, obtain the tax and employer registrations that apply, and clear the required local and activity permissions. A sole proprietor’s route can differ from an LLC’s; incorporation is one possible branch, not the whole process.
This guide uses the United States framework with California and San Francisco examples, verified on October 19, 2026. Use the same questions elsewhere, but follow that jurisdiction’s own agencies and rules rather than copying these filings.
Key takeaways
- An individual business may need local and tax registrations without a company-formation filing.
- Choose the legal operator before entering names in applications.
- Trade-name filings can depend on earlier local registration evidence.
- Federal EIN, state seller and employer accounts have different triggers.
- Opening permissions depend on the actual location and activity, including home operations.
Choose the right registration starting point
Describe the owners, intended activity and operating location so the first filing matches the business.
How to register a business: choose who will operate it
Choose the owner and the real operating location before opening a filing account. Write down who will sign customer contracts, where work will happen, what will be sold, and whether anyone will be employed. These facts decide which registration route to test; a preferred brand alone does not identify the operator.
For a concrete comparison, the California Secretary of State’s entity guidance says a sole proprietor files no formation documents with that office. State registration of a general partnership is optional. An LLC follows an Articles of Organization route, while a corporation files Articles of Incorporation. Those are California examples, not rules for every country or every partnership form.
The structure decision also changes responsibility for business obligations. A sole proprietor remains responsible for the business’s liabilities; forming a separate entity involves a different legal arrangement. Do not choose a sole proprietorship solely because it has fewer formation steps. Have a lawyer or tax adviser assess liability, ownership and tax consequences before you commit.
If an existing business is expanding, identify its current legal owner first. The SBA’s business launch guidance explains that an entity operating beyond its formation state may need foreign qualification. Creating another company is therefore a decision to assess, rather than an automatic first step. Check the receiving state’s rules against the actual activity.
When a separate entity is the chosen route, US company registration and LLC formation support covers a different task from registering an individual’s local business. Settle that choice before requesting an entity filing.
Use four switches to route the remaining work
Use the following routing card after identifying the operator. Mark each row “yes,” “no,” or “needs confirmation,” and name the person responsible for resolving it. A “no” answer should explain the facts behind it; it should not simply mean that no application has been submitted.
Four switches for the registration plan
| Question to answer | If the answer is yes | What to resolve before marking no |
|---|---|---|
| Will a different trading name be used? | Ask which name filing applies to this operator and location. | Confirm the exact legal name and the local naming test. |
| Will there be payroll or taxable transactions? | Identify each federal and state account separately. | Check the actual transaction and other identifier triggers. |
| Will the business use an operating address? | Check local registration and the permitted use of that address. | Include home working, inventory and other real activity. |
| Is the product, service or profession regulated? | Identify the issuing regulator and approval conditions. | Explain the activity precisely to the appropriate authority. |
The card is a planning method, not an exemption test. The SBA’s location and licensing framework ties requirements to the business’s location and activity. Choose the operator first , then resolve each relevant switch against the authority’s own instructions. The order of final applications can change when one office requires another office’s evidence.
Resolve the legal name and trade name separately
Keep legal identity and trading name separate in your registration notes. An individual’s business, a partnership and an LLC may sell under similar branding while having different legal holders. Record both the holder and the name customers will see, then use the appropriate name in each application field.
California’s Secretary of State says a sole proprietor using a name other than the individual’s name must file a Fictitious Business Name Statement with the county of the principal place of business. Review the California sole-proprietor naming route before assuming that a website name or social-media account completes the name work. For other structures, confirm the applicable name rules with the registry and county.
A local dependency can reverse a generic checklist. Under San Francisco Business and Tax Regulations Code section 857 , the County Clerk requires a registration certificate or other evidence of compliance with business-registration rules before accepting a fictitious-name statement. Plan to obtain that evidence first, and ask the Clerk which current filing and publication instructions apply to your case.
Activate tax and employer registrations when triggered
Treat tax registration as a set of conditional accounts. An Employer Identification Number (EIN) identifies a federal tax account; state seller and employer registrations answer different questions. Record the agency beside every identifier so that the numbers are not used interchangeably.
Federal identifier and overseas access
The IRS EIN application guidance lists hiring employees and operating a partnership or corporation among the general EIN triggers. For a new LLC or corporation, it directs applicants to form the entity with the state first. For a sole proprietor, check the listed triggers instead of assuming either that an EIN is compulsory in every case or that no federal obligations exist.
Online access has its own eligibility conditions. The IRS tool requires a domestic organization, a principal place of business in the United States or its territories, and the responsible party’s SSN or ITIN. Where the principal place of business is outside the United States, the IRS directs applicants to phone, fax or mail routes. Save the EIN confirmation letter when issued; an application receipt is not the assigned number.
California sales and payroll switches
The California Department of Tax and Fee Administration seller-permit guidance requires a seller’s permit when a person is engaged in business in California and intends to sell or lease tangible personal property ordinarily subject to sales tax at retail. The test can apply to individuals as well as entities. Classify what is actually supplied: calling the business a service does not settle the treatment of every transaction.
Hiring creates another state check. The California Employment Development Department employer guidance sets a business-employer registration trigger where employees are hired and wages exceed US$100 in a calendar quarter. That figure is a wage threshold, not a registration charge. Household employment has a different test. Review the current registration deadline when planning the first payroll, and assign someone to manage the resulting reporting obligations.
Connect the accounts before filing
Bring the operator, principal business location, hiring plan and sales description for a registration-scope discussion.
Apply the route to a San Francisco sole proprietor
Consider an illustrative individual opening a design consultancy from an address in San Francisco under a new brand. Assume no employees initially and no intended sale or lease of tangible goods. These facts describe the example only; they do not establish an exemption from professional, tax or premises rules.
- Identify the individual as the operator. Under the California sole-proprietor route, there is no Secretary of State formation filing to commission.
- Confirm the address and proposed use. Give the planning authority the actual activity, including any customer visits or later use of the space.
- Complete the local registration route using the owner’s identity, then obtain the evidence the County Clerk needs for the fictitious name.
- Check EIN triggers and the classification of the supplies. Add the employer registration review if hiring begins, and revisit the seller route if goods are added.
For this local step, the San Francisco Treasurer and Tax Collector’s registration instructions request the legal structure, tax identifier, accessible email, operating addresses, and receipts and payroll estimates. The instructions also distinguish individual owner names from registered entity names. Use the relevant fields consistently; do not enter only the consultancy’s brand where the application asks for the legal business name.
Complete the signature and any next steps shown by the application, rather than treating an unfinished online session as registration. The Treasurer’s instructions describe an emailed DocuSign step and subsequent confirmation and payment directions. Retain the signed application and the resulting registration evidence, then follow the separate County Clerk route for the name.
Premises remain an independent decision. SF Planning’s small-business guidance says starting, renovating, expanding or changing the type of business at an existing location may require a permit. It asks applicants to establish the description, address, zoning and permitted uses. Check those points before making a location commitment that depends on approval; the registration application does not resolve them.
If the same founder instead selects a California LLC, add the entity formation branch before its EIN application and use the accepted entity name in later records. The name, tax, local and activity questions still need answers. This contrast shows why “register a business” cannot be reduced to “incorporate a company.”
Decide whether the business can start operating
Finish with a decision about the planned activity, not the number of forms submitted. A registration receipt does not prove permission to begin every activity. Match the owner, name, address and activity across the records that actually apply. If an approval is pending, state which operation must wait for it.
A useful completion review asks three questions: Have required registrations been accepted? Have required operating approvals been issued with any conditions satisfied? Who will maintain the records afterward? Keep unresolved points visible instead of labelling the entire business “approved.” For a conditional decision, record the authority contacted, the facts provided and the response received.
The CDTFA expressly distinguishes its seller’s permit from a city or county business license and directs businesses to the local licensing office. Check that separation in the state’s seller-permit guidance . For a fuller treatment of the permission stage, read the US permissions that follow business registration .
Assign continuing duties when each record is issued. San Francisco’s registration instructions require annual renewal by the last day of February and display of the certificate at the place of business. CDTFA requires notification of changes including address and ownership. Put the applicable dates and change duties in an operating calendar, with a named owner rather than a general reminder to “stay compliant.”
To decide how to register a business, confirm the operator, resolve the applicable switches, and retain the resulting evidence. Proceed with the specific operation only once its required approvals and conditions are satisfied. If the location, products, employees or legal holder later change, reopen the affected questions before relying on the original route.
Turn the route into assigned next steps
Bring the completed records and unresolved authority questions to plan the remaining setup work.
Frequently asked questions
Can two people use the sole-proprietor route together?
A sole proprietorship describes one individual owner. If two people will own the operation, assess the appropriate partnership or entity arrangement before selecting application fields. California’s general-partnership example is a different route from its sole-proprietor route.
Does buying a domain register the business name?
A domain records an internet address. It does not complete an applicable entity-name or fictitious-name filing. The SBA treats domain, entity, DBA and trademark registration as separate systems.
Can the registration be completed entirely online?
That depends on the agency and applicant. The IRS online EIN tool has specific eligibility conditions; an overseas principal place of business leads to another application route. Local signatures, supporting evidence and permits also need their own review.
What if I have no employees when the business starts?
Review other EIN triggers and any seller or local registration requirements. Keep the payroll question open for later hiring; a plan with no current employees is not a permanent conclusion about employer registration.
Can I reuse the original registration after changing ownership?
Do not assume so. Identify which records need an amendment, closure, replacement or new application. CDTFA specifically requires notification of ownership changes, and an EIN may also need review when the operator changes.
