How to Start an LLC in 2026: The Complete Checklist Nobody Gave You

Laying the Foundation: Name, State, and Registered Agent

Your LLC name must include "LLC" or "Limited Liability Company". It's a legal requirement in every state. Before you get attached to a name, search your state's Secretary of State website to confirm it's available. If you plan to operate under a different brand name, you'll need to file a DBA (Doing Business As) separately, which typically costs $20-100 depending on the state and county (CA, NY, and FL also require newspaper publication, pushing the all-in cost higher). While you're at it, check domain availability and grab the .com early. The name search and decision typically takes one to three days, mostly because you'll change your mind twice.

For most people, the best state to form your LLC is the state where you live and do business. You've probably heard that Delaware or Wyoming offer advantages, and they do for venture-backed startups or multi-state holding companies. If you're a solo founder running an online business or local service, registering in your home state avoids the hassle and cost of foreign qualification, which is the process of registering your out-of-state LLC to legally operate where you actually live. Filing fees range from $35-500 depending on the state, and this decision should take about 30 minutes of research.

A registered agent is a person or service that receives legal and government documents on behalf of your LLC. You can technically be your own registered agent, but most founders choose a service instead. Why? Your registered agent must be available at a physical address during business hours in your state of formation. If you're traveling, in a meeting, or not at home when a process server shows up, you could miss critical legal deadlines. Registered agent services cost about $100-300 per year and take approximately 15 minutes to set up.

Filing Your LLC and Writing Your Operating Agreement

The document that officially creates your LLC is called the Articles of Organization in most states, though some call it a Certificate of Formation or Certificate of Organization. Nearly every state lets you file online through the Secretary of State's website. You'll need your business name, principal address, registered agent information, and whether your LLC will be member-managed or manager-managed. For single-member LLCs, member-managed is the standard choice. Filing takes 30-60 minutes, costs $35-500 depending on your state, and processing times can range from instant approval to four weeks.

An operating agreement is your LLC's internal rulebook. It defines who owns what percentage, how profits are distributed, who makes decisions, and what happens if a member leaves. Many states don't legally require one, but you absolutely need it anyway. Banks routinely ask for your operating agreement when you open a business account. Investors will expect one. And if you ever have a dispute with a co-founder, this document is your only protection. Even single-member LLCs benefit from an operating agreement because it reinforces the legal separation between you and your business. You can draft one yourself using free templates online in 1-3 hours, or have an attorney draft a customized version, which typically starts around $500.

Choosing a Business Address, The Step Most Guides Skip

Your business address shows up in more places than you'd expect. It goes on your Articles of Organization, your EIN (Employer Identification Number) application, your bank account, your Google Business Profile, payment processor applications, invoices, and contracts. Choose poorly and you'll spend hours updating records later, or worse, get flagged during bank verification. This is the step that most LLC formation guides cover in a single sentence, but it deserves serious thought because it affects everything downstream.

You have four realistic options. Your home address costs nothing and banks accept it, but it becomes part of the public record the moment you file your LLC, meaning anyone can look it up. A P.O. box costs $10-30 per month, but most states don't accept them for registered agent purposes, and most banks reject them for business accounts because they're not considered a real commercial address. A virtual office gives you a real street address at a commercial building for $30-200 per month, and you can receive all mail and packages there. A co-working membership runs $200-500 per month and comes with physical workspace, but that's overkill if you only need an address. For most remote founders and solo LLCs, a virtual office strikes the best balance between cost, privacy, and legitimacy.

If you go the virtual office route, verify three things before signing up. First, confirm the address is a real commercial street, not a forwarding mailbox or a coworking lounge desk. Run the address through the save office address checker to confirm it shows as a commercial classification in USPS data. Second, ask whether the provider can supply a lease agreement or utility bill equivalent, because some banks request address verification documents beyond your Articles of Organization. Third, make sure there is an actual physical space behind the address, not just a mailbox — reputable providers operate inside an actual co-working space or commercial building, not just a mail-only suite. Expect to spend 1-2 hours researching providers, and budget $30-200 per month depending on location and services.

EIN, Bank Account, and the Paperwork That Trips People Up

Your EIN (Employer Identification Number) is essentially a Social Security number for your business. You get it free from the IRS, and the online application takes about 15 minutes. You'll receive your EIN immediately upon completion. Even if you're a single-member LLC with no employees, get an EIN anyway. It lets you use your business number instead of your personal SSN on tax forms, W-9s, and vendor applications, which is a meaningful privacy protection. The IRS will also mail a confirmation letter (CP 575) to the address you provide on your application, another reason your business address matters.

Opening a business bank account is where many new LLC owners hit an unexpected wall. You'll need your Articles of Organization, your EIN confirmation letter, a government-issued photo ID, your operating agreement, and proof of your business address. The most common reasons banks reject new LLC applications are using a P.O. Box as the business address, having mismatched addresses across your formation documents and application, and being unable to demonstrate any business activity. That last one is a catch-22 for brand-new LLCs, but most banks understand and will work with you if everything else is clean.

The single most important thing you can do to avoid banking headaches is keep your address consistent across every document. Your Articles of Organization, EIN application, bank account application, and any other business filings should all show the exact same address, formatted the same way. One typo or variation can trigger a manual review or outright rejection. As for choosing a bank, online-first banks like Mercury or Relay tend to approve new LLCs faster and charge lower fees, while traditional banks like Chase or Bank of America offer in-person relationships, cash deposit capabilities, and stronger business credit-building opportunities. Many founders start with an online bank for speed and add a traditional bank relationship later.

Licenses, Taxes, and Keeping Your LLC in Good Standing

Business licenses and permits exist at three levels: federal, state, and local (city or county). Most small LLCs don't need a federal license unless they operate in a regulated industry like alcohol, firearms, or transportation. At the state and local level, requirements vary widely. For example, a freelance designer in Texas has different obligations than a food truck operator in California. The SBA's licensing guide at sba.gov/business-guide/launch-your-business/apply-licenses-permits is a useful starting point for figuring out what applies to your specific business and location. Budget 1-5 days and $30-500 or more depending on your industry and municipality.

LLC taxes confuse almost everyone at first, but the basics are straightforward. By default, a single-member LLC is treated as a "disregarded entity" for tax purposes, meaning business income passes through to your personal tax return. You'll pay self-employment tax of approximately 15.3% on net earnings, covering Social Security and Medicare, plus your regular income tax rate. You're also required to make quarterly estimated tax payments to the IRS if you expect to owe more than $1,000 in a given year. Some states add their own layer. California, for example, charges an $800 minimum franchise tax annually regardless of revenue. A good accountant typically starts around $300-500 per year for tax filing alone, more if you need ongoing bookkeeping, and for most LLC owners, that often saves more in taxes and penalties than it costs.

After formation, your LLC has ongoing obligations to stay in good standing. Most states require an annual report or statement of information, which is a brief filing that confirms your business details are current. Miss it, and your LLC can be administratively dissolved. General liability insurance is strongly recommended for any business that interacts with clients or the public. If you hire employees, workers' compensation insurance is required in most states. The total timeline from choosing a name to having a fully operational LLC with a bank account is roughly one to two weeks if you're focused, or three to five days if you clear your schedule. Total cost ranges from $100-1500 depending on your state and the services you choose. You don't need to get everything perfect on day one. Most of these decisions are reversible. Filing your formation papers is the only step that has to happen first; everything else can be tuned along the way.
