Starting a business is common: in 2025, an average of 360 out of every 100,000 adults in the United States became new entrepreneurs each month. But how long it takes to incorporate largely depends on where you’re incorporating and how complicated your business structure is. For example, a Delaware C corporation can incorporate in a few days with an incorporation service that handles the Employer Identification Number (EIN), files tax elections, and completes the state filing. Approval can take days or weeks depending on the jurisdiction. Your early choices determine your timeline.

Below, we discuss how your state and entity type shape the timeline, what filing articles of incorporation involves, and how founders can compress the process from weeks into days.

Key takeaways

• Incorporation timing depends mainly on the state you file in, the entity type you choose, and whether you file online or by mail.

• Getting incorporated is the first step: an EIN, founder stock issuance, and the 83(b) election all have their own separate timeframes and deadlines.

• Paperwork errors such as name conflicts or missing registered agent information commonly cause delays, and most are avoidable with preparation.

What factors affect how long it takes to incorporate a startup?

Location and submission methods strongly affect your timeline.

Here are the factors that can shift the timing:

• State speed: Some secretaries of state review applications faster than others, and turnaround times can increase with seasonal filing volume. For instance, January and early spring tend to move more slowly because many new entities form then.

• Entity complexity: A simple C corp typically clears review more quickly than a corporation with multiple classes of stock or unusual company bylaws.

• Submission method: Submitting incorporation documents online is typically faster than mailing them.

• Name availability: If your chosen business name is already taken in your state of formation, you’ll need to search for and reserve an alternative before you can file.

• Registered agent setup: Every state requires a registered agent; if none has been appointed in advance, it’s an extra task that stands between you and a completed incorporation.

How do your business structure and state choice affect your incorporation timeline?

Because business structure and choice of state are two of the biggest influences on your incorporation timeframe, consider a few factors when making those decisions.

One state stands out for location:

• Delaware’s speed advantage: Delaware’s Division of Corporations runs one of the fastest filing systems in the country. Standard processing typically takes several business days, and expedited options can turn submissions around the same day or within 24 hours.

• Why Delaware dominates startup formation: Investors and lawyers understand its courts and corporate law well, which is a big reason venture-backed startups often choose to incorporate there, with no physical presence in the state.

You’ll also need to choose whether to start a corporation or a limited liability company (LLC). While LLCs aren’t technically formed, they follow a similar state-filing process.

Here’s what to know when making that decision:

• The double-filing risk: If you form an LLC first and later convert to a C corporation to raise venture capital, you typically need to complete another round of formation paperwork. If institutional funding is already part of the plan, you can incorporate as a Delaware C corp from the outset to avoid the later conversion and the delay it adds.

• Different prep times: Corporate filings generally require more information than LLC filings, including share structure and sometimes initial directors, which LLCs don’t need to specify. This doesn’t necessarily mean LLCs get faster approval, since states usually process both entity types through the same office and review queue, but it does mean LLCs can be ready for submission much sooner.

How long does it take to file articles of incorporation?

Once you’ve picked a state and entity type, you can choose standard or expedited service. Standard turnaround times vary widely by state, from same-day in a few places to two or three weeks in others. Expedited processing, which isn’t offered in all states, compresses that to 24 hours, same-day, or, in some states, just a couple of hours, usually for an added fee.

The submission method matters as much as location. Mailing paper articles of incorporation adds transit time on both ends, plus whatever backlog the state office has when your envelope arrives. Filing online, whether directly through the state’s portal or via a formation service that submits documents on your behalf, skips the mail time and often lands in a faster processing queue.

Formation services can be especially helpful here because they often catch errors, such as an unavailable business name, a missing registered agent designation, or an incomplete form field, that can cause submissions to be rejected. This helps avoid resubmission.

What steps come after you incorporate?

Getting your certificate of incorporation back from the state is just the first step.

Several other steps remain before the organization can operate:

• Getting an EIN: If you apply online directly with the Internal Revenue Service (IRS) and have a valid Social Security number (SSN) or Individual Taxpayer Identification Number (ITIN), you can receive the number the same day. If you don’t have an ITIN or SSN, Form SS-4 has to be faxed or mailed instead, and that route can take up to 30 days after receipt.

• Issuing founder stock: This happens through board and stockholder consent documents; it’s typically quite fast once you have the corporate formation documents.

• Filing the 83(b) election: When founders receive stock subject to vesting, they are required to submit the 83(b) election with the IRS within 30 days of the stock grant. Extensions aren’t allowed. If they miss the 83(b) deadline, founders can lose the opportunity to be taxed on the stock’s value at transfer rather than as it vests, which can mean a higher tax bill if the shares appreciate.

• Opening a business bank account: Banks typically require an EIN and formation documents before they’ll open an account. Once both are available, opening the account usually takes a day or two.

What can delay incorporating a startup?

A few specific missteps account for many of the delays founders run into. Nearly all of them are avoidable.

Here’s what to keep in mind:

• Name conflicts: If your chosen name is already taken or too close to an existing entity’s name in your state of formation, you’ll need to pick a new one before the state accepts your filing; that search-and-refile cycle can add days.

• Registered agent errors: Missing or incorrect registered agent information causes similar rejections since states won’t process a filing without a valid agent designated.

• International founder gap: Without a US Social Security number, the same-day online EIN application isn’t available, and the fax or mail alternative using Form SS-4 stretches that step to weeks instead of hours.

• Compounding EIN delay: Several downstream steps, including opening a bank account, rely on the EIN. A slow EIN registration can considerably delay an otherwise fast incorporation process.

• Double cost of paper filing: A mailed filing that’s rejected for a name conflict or missing document costs you the mail time in both directions plus a second trip through whatever backlog exists at the state office.

• Unpredictability of a backlog: State office backlog is the one factor you have the least control over once you’ve filed. It’s more important to avoid the errors above than try to predict processing speed.

How can you speed up incorporation?

Using an incorporation service can reduce a multiweek process to days. It can file the paperwork for a Delaware C corp with the state, obtain an EIN, and handle the 83(b) election, all in a single flow instead of separate tasks you have to sequence yourself. This matters especially for international founders without a US Social Security number who face a slow EIN registration. A platform that handles the request in the same flow removes the biggest bottleneck.

Incorporation services offer speed and ease compared with managing separate systems and deadlines for state filings, IRS forms, and bank requirements. A founder juggling a state filing portal, a separate EIN application, a bank’s account-opening requirements, and a 30-day tax deadline is more likely to miss something than someone using a single formation flow.
