How to Buy an LLC

Learn how to buy an LLC with due diligence on debts, taxes, and ownership transfer. A practical guide to buying an existing LLC safely in 2026.

What buying an LLC really means

When you buy an LLC, you are not buying a box of assets. You are stepping into an existing business with its own contracts, debts, tax history, and legal obligations. The phrase "how to buy an LLC" covers two very different deals: buying the assets of the business or buying the ownership interest in the company itself. Each path carries different risks and different paperwork. Before you sign anything, you need to know which one you are doing and what you are taking on. If you are starting fresh instead, see our guide to starting an LLC.

Step 1: Do your due diligence before you buy

Due diligence is the process of checking the business before you pay for it. Start with the LLC's formation documents and operating agreement. Then pull three to five years of tax returns, bank statements, and profit and loss reports. Ask for a list of every contract, lease, loan, and lawsuit. Check the state business registry to confirm the LLC is in good standing and has filed its annual reports. A seller who hesitates to share records is a warning sign. If the numbers do not add up, walk away.

Step 2: Choose an asset purchase or an equity purchase

In an asset purchase, you buy the equipment, inventory, customer list, and goodwill, but the old LLC keeps its debts and tax history. This is the cleaner option for most buyers because you do not inherit the seller's liabilities. In an equity purchase, you buy the membership interest itself, which means you take over the LLC as it stands, including its debts, contracts, and past tax exposure. Equity deals are simpler to close but riskier. Talk to a tax professional before choosing, because the two paths are taxed very differently.

Step 3: Transfer ownership and update the records

Once the price is set, the seller signs a bill of sale or a membership interest transfer agreement. The LLC's operating agreement usually explains how ownership changes are approved. Some states require an amended filing with the Secretary of State when members change. You should also update the LLC's bank accounts, business licenses, and insurance policies so they reflect the new owner. If you are buying the whole company, you may want to review our guide on operating agreements to understand the rules you are inheriting.

Step 4: Handle the name, EIN, and tax accounts

If you buy the assets only, you can keep your own LLC and your own Employer Identification Number. If you buy the membership interest, you generally keep the existing EIN because the entity continues. You cannot reuse the seller's EIN for a brand new company. You also need to update the IRS address and responsible party on file. If the seller's LLC has unpaid payroll taxes or unfiled returns, those problems can follow the entity. That is why the asset purchase is often the safer route. See our EIN guide for the details.

Red flags that should stop a deal

Some problems are deal breakers. Unpaid payroll taxes are the biggest one, because the IRS can hold the entity responsible. Judgments, liens, and pending lawsuits against the LLC are also serious. Past years' unfiled tax returns mean the business has not been keeping up with its obligations. A name that is not in good standing with the state, or a registered agent who has resigned, tells you the company has been neglected. Check for all of these before you hand over any money.

Get the transfer in writing

Never close a business purchase on a handshake. Get a written purchase agreement that lists exactly what is included, what is excluded, and who is responsible for which debts. Include a clause that the seller guarantees the accuracy of the financial records. Have both parties sign, and keep copies with your LLC records. A written agreement protects you if a hidden liability shows up later. For the tax side of running the business after the sale, read our guide to paying taxes as an LLC.

Frequently Asked Questions

Can you buy an LLC without buying its debts?

In an asset purchase, yes. You buy the assets while the old LLC keeps its debts and tax history. In an equity purchase, you take over the entity and its liabilities. Most buyers choose the asset route for this reason.

Do I get the seller's EIN when I buy an LLC?

If you buy the membership interest, the LLC keeps its existing EIN because the entity continues. If you buy assets only, you use your own EIN. You can never reuse the seller's EIN for a new company.

What is the difference between buying assets and buying equity?

An asset purchase buys the business property but not the company itself, so you avoid inherited debts. An equity purchase buys the ownership interest, which means you take over the LLC and everything attached to it.

How much does it cost to transfer LLC ownership?

The cost depends on your state. Amending the LLC's records with the Secretary of State typically costs $25 to $200. Legal fees for the purchase agreement can add more.

What happens to past taxes when I buy an LLC?

In an asset purchase, past taxes stay with the seller's LLC. In an equity purchase, unpaid taxes can become your problem because the entity survives. Always review several years of returns before buying.
