Incorporating is the act of creating a separate legal entity with a state’s secretary of state. You file formation documents, pay the state fee, and in return get a company that can own its intellectual property, sign contracts, raise outside money, and keep business debts away from your personal assets.
Learning how to incorporate a startup step by step matters because the order of operations is where founders get stuck. The state filing, the employer identification number, and the bank account all depend on each other, and doing them in the wrong sequence means waiting on hold while your formation sits half-finished.
This guide walks the full sequence for a corporation and a limited liability company, then covers the recurring obligations that begin the day your entity is in good standing. It is general information about U.S. state and federal process, not legal or tax advice for your particular situation.

What You Need
Most founders arrive with a business idea and no paperwork, then stall because they do not know what the state actually asks for. Here is the working set you should have before you touch a filing portal.
- A decided business name, plus two or three backups that pass your state’s naming rules.
- A decided formation state, and a separate answer on where you will physically operate.
- A registered agent named with a physical street address in the formation state.
- Names and addresses for every incorporator, director, member, manager, and officer.
- Share or membership structure: authorized shares, par value, and how ownership splits.
- An operating agreement or bylaws describing how decisions get made and who owns what.
- A founder equity and vesting plan, especially if a co-founder could leave.
- An SSN or ITIN for each responsible person, which is what opens the online EIN application.
- A payment method the secretary of state accepts, since card fees vary by state.
The one item people routinely skip is the operating agreement. It is the document that settles disagreements later, and it costs nothing to draft well.
A word on scope. The steps below cover what a U.S. corporation (C corporation or S corporation election) and a limited liability company require. Registering a foreign entity, forming a nonprofit, or incorporating outside the United States adds steps this guide does not cover.
How to Incorporate a Startup Step by Step
Here is the chronological order that works: decide the entity, check the name, appoint a registered agent, prepare documents, file with the state, get your EIN, adopt governance records, handle taxes, then lock in a compliance calendar. The table below is a quick reference for effort, cost, and elapsed time at each stage.
| Step | Typical cost | Typical time | Who does it |
|---|---|---|---|
| Choose entity type | Free to a few hundred dollars with advice | 1 to 3 days of research | Founders, with a lawyer if stakes are high |
| Check name availability | Free state search, small extra if you reserve | 30 minutes to 2 days | Founders |
| Appoint registered agent | Annual service fee if you use a company | Same day | Founders or agent service |
| Prepare formation documents | Template, platform, or attorney | 1 to 7 days | Platform or attorney |
| File with the state | State fee plus any platform markup | Same day to about 10 business days | Founders, platform, or attorney |
| Apply for EIN | Free directly from the IRS | Instant online, or several days by fax | Responsible person |
| Adopt bylaws and board action | Template or attorney | 1 to 3 days | Board or members |
| Open bank and payment accounts | Usually no setup fee | 1 to 10 business days | Founders |
| File foreign qualification where you operate | State fee in your home state | Several days to a few weeks | Founders or a lawyer |
| Set up bookkeeping and payroll | Software subscription | First month | Bookkeeper or accountant |
Timing figures above reflect the range most founders see, not a guarantee. States publish their own processing times, and those change.
How to Incorporate a Startup Step by Step: Choose Your Business Entity
The entity choice is the one decision that is expensive to reverse, so it deserves a real conversation rather than a default. Three structures cover nearly every U.S. startup.
| Factor | Limited liability company | S corporation | C corporation |
|---|---|---|---|
| Liability protection | Yes, for members who keep records clean | Yes, for shareholders who keep records clean | Yes, the strongest and most tested standard |
| Federal taxation | Pass-through by default | Pass-through, with eligibility rules | Entity-level tax, plus tax on dividends to shareholders |
| Ownership limit | Unlimited members | Up to 100 shareholders | Unlimited shareholders |
| Investor acceptance | Limited; angel-friendly, VC-hostile | Limited; same constraint as LLC | The default venture structure |
| Equity compensation | Possible, but less flexible | Possible | Standard stock option and restricted share plans |
| Administrative load | Lightest | Light to moderate, plus payroll forms | Heaviest: bylaws, board minutes, annual report |
| Typical funding fit | Bootstrapped services, consulting, small product work | Profitable small business with profits and no VC plans | Venture-backed and enterprise-facing startups |
If you plan to raise venture capital, hire people, and issue options, a Delaware C corporation is the conventional answer. It is standardized enough that funds, accountants, and lawyers already know how to read it, and that predictability is worth the extra paperwork.
If you are bootstrapping a consulting or services business with one or two owners and no outside investors, a single-member LLC does the same job with less annual reporting. Get professional advice when ownership is complicated: multiple co-founders, foreign owners, or a funding round with preferred terms attached.
Choose a Unique Name and Check Availability
Your state’s business database must show that the name is available, and the suffix requirements differ. Many states want “Corporation,” “Incorporated,” “Limited Liability Company,” or “L.L.C.” spelled out or abbreviated, and some require the name to be distinguishable from existing names on a broader standard than exact match.
Check four places before you commit. Start with the secretary of state’s business entity search. Then search the federal trademark database to see whether anyone has claimed the mark in your class. Check the domain name and common social handles, because a name you cannot buy is a name you cannot use. If you plan to sell through an app store, a marketplace, or a city procurement portal, search those naming systems too.
How you know it worked: the state search returns no near-match entity, and you can register the matching domain and handles right now.
Appoint a Registered Agent and Registered Office
A registered agent is the person or company that accepts legal and government correspondence on the entity’s behalf during business hours. The registered office is the physical street address where that agent is located, and in most states it must be an address where someone is actually present, not a post office box.
Three options exist. An officer or founder can serve, which is cheap but exposes that person’s name to filings and means service of process lands at their desk during work hours. A professional registered agent company costs an annual fee and gives you a separate address and a consistent point of contact. An individual non-founder can serve in some states, which works when you have a trustworthy co-founder who prefers not to use their own address.
How you know it worked: the filing was accepted with the agent’s consent on record, and the state confirms the agent’s address. If you are operating remotely or from a different state, remember that the registered office still has to sit in the formation state.
Prepare Formation Documents
Corporations and LLCs are built from different paper sets. A corporation files a certificate of incorporation that lists the company name, the registered agent, the authorized shares, and the par value of each class, then adopts bylaws that set out board powers, meeting rules, and stockholder rights.
A person who signs the certificate sometimes appears only as the incorporator, and that person’s action is then documented by a separate action-by-incorporator or written consent. Once the entity exists, the incorporator steps aside and the directors or members take over.
An LLC files articles of organization, which is a much shorter document, and its governing document is the operating agreement. The operating agreement should cover management structure, voting thresholds, distribution rules, what happens if a member dies or leaves, and the buyout process.
How you know it worked: you have signed originals of the formation document, the governing document, and the initial consent or meeting minutes, all in one place with the filed copy from the state.
File With the State and Pay the Fee
File with the secretary of state of the state you chose. Some states let you file directly through their online portal; others push you toward approved service providers that handle the submission as your authorized representative. Both routes end at the same office.
Before you submit, check what that specific state requires: online account registration, a cover page, the filer contact details, payment method, and whether expedited review is available for an extra fee. Standard review is the norm; expedited review shortens the wait.
You will receive a confirmation and, once accepted, a stamped copy of the filed document. That stamped copy is the company’s proof of existence. Keep a permanent record of it, along with the filing receipt.
How you know it worked: the state issues a file number and a stamped document. If you get a rejection notice instead, the reason is usually a formatting, name, or payment problem, and you can correct and resubmit quickly.
Fees, forms, and processing times change across all fifty states. Read the fee schedule on the secretary of state’s own site before you submit, since a third-party platform adds its own service charge on top of the state fee.
Get Your EIN and Business Accounts
The employer identification number identifies your entity to the IRS and to most banks. The current application is Form SS-4, and the IRS offers a free online application that issues the number immediately when the responsible person’s details match IRS records.
That matching detail matters. The online path asks for a social security number, and a mismatch or typo sends you to a phone call or a fax that adds days. If you are a non-U.S. founder without an SSN, you can apply by phone with an ITIN, or by fax, and expect a slower response. An authorized representative can also request the number on your behalf, though some platforms charge for that service.
Once you have the number, open a business bank account in the entity’s exact legal name, then add a merchant account or payment processor for collecting revenue. Keep the entity’s money physically separate from your own from the first transaction. Commingling funds is the single fastest way to lose liability protection.
How you know it worked: the legal name on your bank account, your EIN confirmation letter, and your filed formation documents are identical, character for character. Also file the IRS determination letter, which banks ask for constantly.
Complete Post-Incorporation Requirements
Filing is the midpoint, not the finish line. Founders routinely stop here and then discover later that their own state never received a notice they were required to send.
Adopt your bylaws or operating agreement with a dated board or member consent. Hold an initial organizational meeting to appoint officers, approve the bank account, adopt a conflict of interest policy, and authorize the founder share issuance. Write the IP assignment agreement and have every person who has touched the code or product sign it, then store it with the governing documents.
If you incorporated outside the state where you actually work, file to register as a foreign entity there. That registration, called foreign qualification, is what lets you bring a suit, open a local account, and bid on local work in that state. Founders who skip it are technically operating without authority in their home state.
How you know it worked: a corporate or LLC record book exists, contains the formation documents, the governing document, the initial consent, and the IP assignments, and every founder has signed copies.
Set Up Taxes, Payroll, and Fundraising Records
Federal and state tax registration are separate processes, and each has its own onboarding forms. Federal corporate tax registration happens with the IRS. State income tax, franchise, or privilege tax registration happens with that state’s revenue department, and your home state may require a registration before you have collected a single dollar of revenue there.
Compensation and distributions are different things. Payroll is how founders take money for working; distributions are how the entity pays shareholders out of profit. Mixing them confuses the books and the payroll filings, so decide early how founders get paid and document it in a written plan.
Before you raise anything, have three things in order: the cap table showing every share issued and every option promised, signed founder equity and vesting agreements, and a data room with formation documents, the cap table, the IP assignments, and the incorporation certificate. Investors will ask for all of it, and a clean data room closes faster than a reconstructed one.
A stock option pool is typically sized and set aside at formation so there are shares available to grant later. Decide that number before you issue founder shares, because adding pool shares later dilutes everyone.
How you know it worked: your accounting system has the entity set up, the cap table reconciles with the share ledger and the formation documents, and every founder has a signed vesting agreement.
Maintain Ongoing Compliance
Good standing is not a one-time achievement. Every jurisdiction you registered with has its own recurring deadline, and missing one produces penalties that accumulate until the state begins administrative dissolution proceedings.
Here is what to put on the calendar, using relative dates rather than fixed ones so you can re-anchor each year:
- Annual report or renewal with the secretary of state, usually in the anniversary month of formation.
- Franchise tax or business privilege tax, which a Delaware corporation owes by March 1, with minimum amounts due even with no revenue.
- State income tax registration and annual return in every state where you have economic nexus.
- Federal corporate income tax return, filed on the corporate calendar rather than the personal one.
- Payroll registrations, quarterly withholding filings, and annual wage reporting once you have employees.
- Beneficial ownership information reporting, which applies to most U.S. entities created after a specific date and updates when ownership changes.
- Registered agent renewal with the agent and with the state.
- Local business license and vendor registration, which lives at the city or county level, not the state.
For a startup selling into cities and public agencies, the local layer matters as much as the state layer. City vendor registration gets your company into the procurement system so you can bid. A state or local business license may be required before you can operate at all. Street-level pilots may need public-space permits, and handling transit, utility, or mobility data usually means signing a data use agreement before you touch a single record.
Books, minutes, and governance records need the same recurring slot. Block one hour a week to capture board and member decisions, and send the bookkeeping to a professional once monthly rather than trying to catch up in April.
How you know it worked: you can answer three questions for any deadline: when is it due, who owns it, and where is the confirmation. If any answer is blank, the calendar is not doing its job.
Common Mistakes
Almost every expensive founder mistake traces back to one of these. Each has a straightforward fix.
Choosing the entity by default instead of by plan. An LLC formed by reflex becomes a real obstacle at a venture round. Fix: write one page describing how you expect to be funded and paid in three years, then match the entity to it.
Using inconsistent names across records. A bank account in a slightly different name, or a filing that abbreviates “Corporation” one way and your contracts another, slows every verification step. Fix: copy the legal name character for character from your stamped formation document into every other record.
Commingling personal and company money. Courts and agencies look for exactly this when testing whether to treat you and the company as one. Fix: dedicated account, dedicated card, no exceptions in the first year.
Missing the 83(b) election window. If a founder receives restricted shares subject to vesting, that election is due within 30 days of the transfer and is generally treated as final once the window closes. Fix: put the date in the calendar the day shares are issued, and file proof with the company records. Nobody can undo a missed election.
No vesting. Co-founder equity without a vesting schedule is a standing dispute waiting for a bad month. Fix: a four-year vesting schedule with a one-year cliff is the common default, written into each founder’s agreement.
Skipping the IP assignment. Code written before incorporation belongs to whoever wrote it by default. Fix: a written assignment from every contributor to the company, dated and filed with the record book.
Ignoring local registration. A valid state entity says nothing about whether you can bid on a city contract or run a street-level pilot. Fix: check the city procurement office and local license requirements early, before you need the credential.
Over-filing in states you do not operate in. Every extra registration is another filing fee and another renewal. Fix: register where you have people or real economic activity, not where you imagine having them.
Treating incorporation as liability protection on its own. The protection depends on behavior, not on the certificate. Fix: separate accounts, contracts in the entity’s name, minutes kept, taxes filed. Do all four and the structure holds; skip them and courts can reach past it.
Two habits help more than any single tactic. Get a short written plan before filing, and set the recurring deadlines in a calendar before you think you need one. When the stakes are high, an hour with a startup attorney is cheap compared with converting a C corporation to an LLC after a round has closed.
Frequently Asked Questions
How long does it take to incorporate a startup?
The state filing itself can be accepted the same day, and most states process standard reviews within about ten business days. The rest of the setup is what takes calendar time: an EIN issued online can be immediate, while state tax registration and foreign qualification each add several days to a couple of weeks. Most founders finish end to end in two to four weeks.
What is the difference between incorporating a startup and registering a business?
Incorporation creates a new legal entity at the state level, with a filing, a fee, and ongoing annual obligations. Registering a business is usually a local or state license that lets a business operate in a particular jurisdiction, often tied to a location or type of work. One gives you liability separation and contracts; the other gives you permission to do business in a place.
Should a startup be an LLC or an S corporation?
Both are pass-through for federal tax purposes, but an S corporation requires eligible shareholders and creates payroll filing obligations. An LLC is simpler and works for a bootstrapped services business. If you plan to hire, sell stock options, or raise venture capital, a Delaware C corporation is usually the better fit. If you are unsure, ask a tax professional before you file.
Do I need a registered agent to incorporate a startup?
Yes. Every U.S. state requires a registered agent with a physical street address in that state, and the state will reject a filing without one. An officer can serve for free if they are present during business hours. Otherwise you pay a professional agent an annual fee, which also gives you a separate address for official correspondence.
How much does it cost to incorporate a startup?
Three things drive the total: the state filing fee, the registered agent fee if you use a professional, and who does the paperwork. Filing directly with the state is always the cheapest route. An incorporation platform costs less than a startup attorney, and neither adds legal judgment a DIY filing cannot supply. Check the current fee schedule on the secretary of state’s own site, since fees and rates change.
What should I do immediately after incorporating a startup?
Adopt your bylaws or operating agreement, hold the initial meeting and record resolutions, open a business bank account in the exact legal name, and assign all intellectual property to the company. If you are not based in the formation state, file foreign qualification next. Knowing how to incorporate a startup step by step means treating formation as the midpoint rather than the finish line.
Conclusion
The action sequence is short enough to memorize: pick the entity and state, confirm the name is available, appoint a registered agent, prepare the formation and governance documents, file and pay the state fee, get the EIN, open accounts in the exact legal name, register for taxes and foreign qualification, then calendar every recurring deadline.
The harder part is the second half. Bylaws, IP assignments, vesting, and a first-year compliance calendar are what separate a clean entity from a risky one. Put them on the calendar before you need them, and get a qualified attorney or tax professional involved when ownership, funding, or equity is complicated. This is general U.S. information, not individual legal or tax advice, and state rules change often enough that you should confirm current requirements before you file.
