How long does it take to start an LLC?
The short answer: anywhere from same-day to a few weeks. It depends on two things — your state's processing speed and how you file. Here's what to expect at each step.
Fastest
Same day
Online filing in fast states, or paid expedited processing
Typical
3–10 days
Online filing in most states
Slowest
2–4+ weeks
Mail filings, or states with backlogs
How you file changes everything
The same state can be fast or slow depending on the filing method. These are typical ranges — your state's Secretary of State website publishes its current processing times.
| Filing method | Typical approval time | Good to know |
|---|---|---|
| Online | Same day – 1 week | The default in most states, and almost always the fastest option. |
| 2 – 4+ weeks | Adds delivery time and manual handling on both ends. | |
| Expedited | Same day – 3 days | Most states offer rush processing for an extra fee, often $25–$100+. |
| Formation service | State time + a few days | They prepare and submit for you — helpful, but the state's clock still applies. |
The full timeline, start to finish
State approval is only the middle of the journey. Here's how the whole thing usually plays out.
Pick a name and file your paperwork
Search your state's registry, confirm the name is free, and submit your Articles of Organization online. This takes an afternoon, not a week.
Wait for state approval
The state reviews and approves your filing. Online filings in most states come back within about a week; mail takes longer.
Your LLC officially exists
Once approved, your LLC is a legal entity. You'll get a stamped copy or certificate — save it, your bank will ask for it.
Get your EIN
Apply free at IRS.gov and receive your EIN immediately online. No waiting required.
Open your business bank account
Bring your approved Articles, EIN, and operating agreement to the bank. Many banks open accounts same-day or within a few business days.
Realistic total: about 1–2 weeks from first search to a bank-ready LLC for most online filers.
Four ways to avoid delays
File online, not by mail
Online filing skips weeks of mail time and often gets priority in the state's queue.
Check your name first
A name conflict is the most common rejection. Search your state's registry before you file, not after.
Double-check every field
Typos and missing signatures mean a rejection and a restart. Slow down on the form to speed up the approval.
Use expedited processing if it matters
Launching on a deadline? Most states sell same-day or 24-hour processing for a modest fee.
Common questions
How long does it take to start an LLC?
Most LLCs are approved within a few days to a few weeks. Online filings in fast states can be approved the same day, while mail filings in slower states can take several weeks. Your state's Secretary of State website lists current processing times.
What is the fastest way to start an LLC?
File online directly with your state. Many states process online filings within 1 to 5 business days, and some approve them immediately. If you are in a hurry, most states also offer expedited processing for an extra fee.
Can I start an LLC in one day?
Sometimes. A few states approve online filings the same day or within 24 hours, and most states sell expedited or same-day processing for an added fee. Check your state's filing office for its current turnaround.
Does filing by mail take longer?
Yes. Mail filings typically add one to three weeks on top of the state's processing time because of delivery and manual handling. Filing online skips most of that delay.
Is my LLC active as soon as the state approves it?
Yes — your LLC legally exists once the state approves your Articles of Organization. But before you operate, you will usually want your EIN, an operating agreement, and a business bank account, which add a few more days.
How long does it take to get an EIN?
If you apply online at IRS.gov, you get your EIN immediately. Fax applications take about four business days, and mail applications can take four to five weeks.
Do formation services make the process faster?
A formation service does not control the state's processing speed, but it helps you avoid filing errors that cause rejections and restarts. Many also offer expedited state processing as an add-on.
