How to Open an LLC

Learn how to open an LLC from filing to your first sale. A step by step guide to formation, EIN, bank accounts, licenses, and the real timeline to launch.

What opening an LLC really means

If you want to know how to open an LLC, the good news is that the paperwork is only half the job. Filing your articles of organization creates the legal entity, but the company does not really feel open until you have an EIN, a bank account, and any licenses you need. This guide walks through the full going live process so you know what to expect at every step.

Opening an LLC means two things. First, you file formation documents with your state to create the legal entity. Second, you set up the practical pieces that let the business actually operate, like a tax ID, a bank account, and the right permits. Many owners finish the filing in an afternoon and then spend a week or two on the setup work. The filing alone does not make you ready to do business.

Step 1: File your formation documents

Every state has its own form, usually called the articles of organization or certificate of formation. You file it with the Secretary of State, and fees run from about $40 to $500 depending on where you live. The form asks for your LLC name, your registered agent, and the address of the business. You can file online in most states and get approval in a few days to a few weeks. See our guide to creating an LLC for the full filing walkthrough.

Step 2: Get an EIN from the IRS

Once your state approves the filing, apply for an Employer Identification Number from the IRS. The EIN is free and takes about 10 minutes online. You need it to open a bank account, pay taxes, and hire anyone later. The IRS issues most EINs instantly when you apply through its website. Our EIN guide covers the application step by step.

Step 3: Open a business bank account

A separate business bank account is one of the most important steps after filing. It keeps business money apart from personal money, which protects your limited liability. Banks usually ask for your EIN, your formation documents, and a copy of your operating agreement. Shop around for an account with no monthly fee or a low minimum balance. Many community banks and credit unions offer free business checking.

Step 4: Handle licenses and permits

Depending on your industry and location, you may need a business license, a sales tax permit, or a professional license. Check with your city, county, and state to see what applies. A home based business often needs a local license even when the state does not require one. If you sell physical goods, most states require a sales tax permit before you collect tax from customers.

How long does it take to open an LLC?

Most owners go from filing to fully operational in one to three weeks. The state filing takes a few days to a few weeks depending on the state and whether you pay for expedited processing. The EIN is instant, and a bank account can be opened the same day. Licenses take the longest, sometimes two to six weeks, so start those early. If you are in a hurry, many states offer same day or next day filing for an extra fee.

What comes after you open

Opening the LLC is the start, not the finish. You should create an operating agreement even if your state does not require one, keep business records separate, and mark your annual report deadline on the calendar. Most states charge $50 to $300 per year to keep an LLC in good standing. For the full picture of what it costs, see our cost guide.
