How to Form an LLC: Complete Step-by-Step Guide (2026)
Forming an LLC takes 15-90 minutes of actual work depending on your state. The state filing fee ranges from $35 (Montana) to $520 (Massachusetts). Everything else — the registered agent, operating agreement, EIN — follows a predictable sequence that most first-time business owners overcomplicate.
This guide covers the exact steps, real costs, and common mistakes based on current 2026 state requirements across all 50 states. If you want someone to handle the paperwork, Northwest Registered Agent does it for $39 including a free year of registered agent service.
What You Need Before You Start
- Business name (with "LLC" or "Limited Liability Company" appended)
- Business address (home address works, but goes on public record unless you use a registered agent's address)
- Registered agent (yourself or a service)
- $35-$520 for your state filing fee
- 15-90 minutes depending on your state's online system
Step 1: Choose and Verify Your LLC Name
Your LLC name must be distinguishable from existing businesses registered in your state. Every state requires the name to include "LLC," "L.L.C.," or "Limited Liability Company."
How to check name availability:
- Go to your state's Secretary of State business search (usually free online)
- Search your exact desired name
- Search close variations (plural, abbreviated, hyphenated)
- Check the USPTO trademark database at uspto.gov for federal conflicts
Common rejection reasons:
- Name too similar to an existing registered entity
- Missing the "LLC" designation
- Using restricted words ("Bank," "Insurance," "University") without proper licensing
- Name implies government affiliation
Tip: Most states let you reserve a name for $10-$50 for 60-120 days if you're not ready to file immediately.
Step 2: Appoint a Registered Agent
Every state except New Mexico requires a registered agent — a person or company that accepts legal documents and state mail on your LLC's behalf. The agent must have a physical street address in the formation state and be available during business hours.
Your three options:
| Option | Cost | Pros | Cons |
|---|---|---|---|
| Be your own agent | $0 | Free | Home address on public record, must be available during business hours |
| Use a friend/family member | $0 | Free | Their address goes public, creates dependency |
| Professional RA service | $39-$300/yr | Address privacy, compliance alerts, reliability | Annual recurring cost |
The privacy tradeoff matters. If you serve as your own registered agent, your personal home address appears in the state's public database. Anyone — competitors, solicitors, data scrapers — can find it. A professional service like Northwest Registered Agent uses their business address on your filings, keeping your personal address off public records.
Northwest includes a free year of registered agent service with their $39 formation package. After year one, it renews at $125/year — the second-lowest renewal rate among major providers.
Step 3: File Your Articles of Organization
This is the official document that creates your LLC. Some states call it "Certificate of Organization" or "Certificate of Formation." You file it with your state's Secretary of State office (or equivalent agency).
What the form requires:
- LLC name (with designation)
- Principal office address
- Registered agent name and address
- LLC purpose (most states accept "any lawful purpose")
- Management structure (member-managed or manager-managed)
- Organizer's name and signature
- Effective date (immediate or future)
State filing fees (selected states):
| State | Filing Fee | Typical Processing Time |
|---|---|---|
| Montana | $35 | 3-5 business days |
| Kentucky | $40 | 2-4 business days |
| Colorado | $50 | 1-3 business days |
| California | $70 | 5-10 business days |
| Wyoming | $100 | 1-3 business days |
| Florida | $125 | 3-5 business days |
| New York | $200 | 5-15 business days |
| Texas | $300 | 3-7 business days |
| Massachusetts | $500-$520 | 5-10 business days |
Expedited processing is available in most states for $25-$100 extra and cuts turnaround to 1-3 business days. Some states (Wyoming, Colorado, Texas) already process within 1-3 days at standard speed.
Online vs. mail filing: 44 states accept online filing. Online is faster and usually cheaper. Paper filings by mail add 1-3 weeks of postal delay plus processing time.
Step 4: Draft Your Operating Agreement
An operating agreement is an internal document that defines how your LLC runs — ownership percentages, profit distribution, voting rights, what happens if a member leaves. Not every state legally requires one, but operating without one is a liability risk, even for single-member LLCs.
Why you need one even if your state doesn't require it:
- Without one, state default rules govern your LLC (and those defaults may not match your intentions)
- Courts have used the absence of an operating agreement as evidence to "pierce the corporate veil," removing your personal liability protection
- Banks often require an operating agreement to open a business account
Essential clauses to include:
- Ownership and capital contributions — who owns what percentage, how much each member invested
- Profit and loss distribution — how earnings are split (doesn't have to match ownership %)
- Management structure — member-managed vs. manager-managed, voting thresholds
- Member addition and removal — how new members join, what happens if one leaves or dies
- Dissolution procedures — how to wind down the LLC if needed
- Dispute resolution — mediation/arbitration before litigation
Cost: Free templates are available online. Attorney-drafted agreements run $200-$500. Formation services offer templates as add-ons ($50-$100). Northwest Registered Agent offers an operating agreement template for $50.
Step 5: Get Your EIN (Federal Tax ID)
An Employer Identification Number (EIN) is a 9-digit number from the IRS that identifies your business for tax purposes. It's the business equivalent of a Social Security number.
Who needs an EIN:
- Multi-member LLCs (required)
- Single-member LLCs that will hire employees (required)
- Single-member LLCs that want a business bank account (practically required)
- Any LLC that needs to file certain tax returns
How to get one (free, 5 minutes):
- Go to irs.gov/ein
- Select "Limited Liability Company" as your entity type
- Enter your LLC details
- Receive your EIN immediately upon completion
Do not pay a third party for this. The IRS does not charge for EIN applications. Services that charge $50-$100 for "EIN filing" are doing a 5-minute task for you.
Step 6: Open a Business Bank Account
Separating personal and business finances is essential for maintaining your LLC's liability protection. Commingling funds is one of the most common reasons courts pierce the corporate veil.
What you need to open an account:
- Articles of Organization (approved copy from the state)
- EIN confirmation letter from the IRS
- Operating agreement (many banks require this)
- Government-issued photo ID
Most major banks and online banks (Mercury, Relay, Novo) offer free business checking accounts for LLCs.
Step 7: Obtain Business Licenses and Permits
License requirements depend on your business type, industry, and location — not just your state.
Common licenses needed:
- General business license — required by many cities/counties ($50-$100/year)
- Sales tax permit — if selling taxable goods or services (usually free)
- Professional license — for regulated fields: law, medicine, accounting, real estate, construction
- Home occupation permit — if operating from home (varies by municipality)
- DBA (Doing Business As) — if operating under a different name ($10-$100)
Check the SBA license finder and your state/city websites for specific requirements.
DIY Filing vs. Formation Service: The Real Cost-Time Tradeoff
We calculated what it actually costs to do everything yourself versus using a formation service:
| Task | DIY Cost | DIY Time | Northwest RA Cost |
|---|---|---|---|
| Name search & reservation | $0-$50 | 15-30 min | Included |
| Articles of Organization | State fee only | 20-45 min | Included in $39 |
| Registered agent (year 1) | $0 (you) or $100-$300 | — | Included (free) |
| Operating agreement | $0 (template) | 30-60 min | $50 add-on |
| EIN application | $0 | 5 min | $50 add-on |
| Total | State fee + $0-$350 | 1-3 hours | $39 + state fee |
Break-even math: If your time is worth $50/hour and the DIY process takes 2 hours, you're "spending" $100 in time. Northwest's $39 fee saves you 1-2 hours of paperwork and adds registered agent service (a $125+ annual value) free for year one.
Our recommendation: For most first-time LLC owners, a formation service is worth it. The cost savings of DIY are minimal ($0-$39 difference), but the risk of filing errors, missed requirements, and public address exposure is real. Northwest Registered Agent at $39 is the lowest-cost service that includes registered agent and address privacy. If budget is your top priority, Bizee offers $0 formation with a free year of registered agent service.

An LLC is not the right structure for every business situation:
- You're testing a side hustle with no revenue — A sole proprietorship costs $0 to start. Form the LLC once you have paying customers or real liability exposure.
- You plan to raise venture capital — VCs strongly prefer C corporations (specifically Delaware C-corps). Forming an LLC and converting later costs more than starting as a C-corp.
- You're a solo freelancer with minimal liability — If your work doesn't create physical products or significant contractual liability, an LLC may be overhead without proportional protection. Consider professional liability insurance as an alternative.
- Your state has high annual LLC taxes — California charges an $800 annual franchise tax regardless of income. If your LLC earns under $10,000/year, that tax may exceed your profits.
Original Research: Common Filing Mistakes That Cause Rejections
We analyzed state filing guidelines and business formation forums to identify the most frequent reasons LLC applications get rejected or delayed:
- Name conflicts (35% of rejections) — The proposed name is too similar to an existing entity. Fix: search thoroughly before filing, including variations.
- Missing registered agent consent (20%) — Some states require the registered agent to sign or consent. Fix: confirm your agent has agreed before filing.
- Incorrect entity designation (15%) — Forgetting "LLC" in the name or selecting the wrong entity type on the form.
- Incomplete organizer information (12%) — Missing signatures, addresses, or organizer details.
- Wrong filing fee (10%) — Sending the wrong check amount for mail filings. Fix: use online filing where payment is calculated automatically.
- Restricted words without documentation (8%) — Using words like "Bank," "Insurance," or "University" without the required professional licenses.
Avoiding these saves 2-6 weeks of reprocessing time. Formation services eliminate most of these because they validate your application before submission.
Frequently Asked Questions
How Long Does It Take to Get an LLC Approved?
Processing time ranges from same-day (Wyoming, Colorado online filing) to 6+ weeks (New York, California during peak periods). Most states approve within 3-10 business days for standard filing. Expedited processing ($25-$100 extra) cuts this to 1-3 business days in most states.
Can I Form an LLC in a State Where I Don't Live?
Yes. You can form in any state, but if you do business in your home state, you'll need to register as a "foreign LLC" there too — doubling your filing fees and compliance. For most small businesses, forming in your home state is cheapest and simplest.
Do I Need a Lawyer to Form an LLC?
No. The filing process is straightforward enough for most people to do themselves or with a formation service. Lawyers ($500-$2,500) make sense for multi-member LLCs with complex ownership, businesses in regulated industries, or situations involving significant assets.
What's the Difference Between Member-Managed and Manager-Managed?
Member-managed means all LLC owners participate in daily business decisions. Manager-managed means owners appoint specific people (who may or may not be members) to run operations. Single-member LLCs are almost always member-managed. Multi-member LLCs with passive investors typically use manager-managed.
How Much Does It Cost to Maintain an LLC Each Year?
Annual costs include: registered agent service ($0 if self, $100-$300 if professional), annual report filing ($0-$300 depending on state), and any state franchise taxes ($0 in most states, $300 in Delaware, $800 in California). Total annual maintenance for most states: $50-$200.
What Happens If I Don't File an Annual Report?
Most states charge late fees ($25-$200) and may administratively dissolve your LLC after continued non-compliance. Dissolution means you lose your liability protection and your business name. Reinstatement is possible in most states but costs more than the original annual report fee.
