LLC vs Sole Proprietorship | Which One Should You Choose?
If you're planning to start a business, one of the first decisions you'll face is which management structure actually fits your business.
An LLC and a sole proprietorship are both worth considering — but they're not interchangeable. I've spent years as a Mergers and Acquisitions specialist guiding first-time founders through this exact decision, and I've seen the wrong choice create real headaches down the road.
Here's what you need to know about filing requirements, ownership, liability, and taxes — so you can pick the right structure from the start.
Quick Summary
- An LLC is a business structure owned by several individuals referred to as members, while a sole proprietorship is owned and managed by only one person.
- Members of an LLC benefit from personal liability protection, while a sole proprietor is liable for business debts and obligations.
- As of 2020, there are over 28 million sole proprietorships and 21 million LLCs in the United States.
- In my experience, a sole proprietorship is the best way to establish a new business before expanding into an LLC or a corporation.
At a Glance: LLC and Sole Proprietorship
An LLC is a business entity that gives its owners personal liability protection, pass-through taxation, and a flexible operating structure. One of its biggest advantages: your personal finances stay legally separate from the business.
A sole proprietorship is the simplest and cheapest structure you can set up [1]. There's almost no paperwork involved. The catch? There's no legal wall between you and the business, which means your home, car, and savings account are all fair game if the business gets sued or can't pay its debts.
Between March 2021 and March 2022, 1.4 million US businesses were launched — which tells you just how many people are facing this exact choice right now.

Key Differences
Here's where the two structures actually differ in practice:
1. Filing Procedure
To form an LLC, you'll need to file Articles of Organization, appoint a registered agent, draft an operating agreement, apply for the relevant licenses and permits, and obtain an EIN.
One thing I always tell clients: get your EIN directly through the IRS website — it's completely free, and there's no reason to pay a third party to do it for you.
A sole proprietorship is much lighter on paperwork. You'll register a business name, grab the permits you need, and get an EIN. By default, the business operates under your name unless you register a DBA.
2. Ownership and Management
An LLC is owned by one or more members. Those members can run the company themselves or bring in an outside manager to handle day-to-day operations [2]. It's a genuinely flexible setup.
A sole proprietorship has one owner — full stop. That owner makes every decision, which keeps things simple but also means everything falls on one person.
Manager-managed LLCs have managers that make company decisions separate from the membership.
A sole proprietorship has only one owner (or a married couple) who owns all or most of the business or the owner's personal assets.
That means that sole proprietors don't have the personal liability protection that LLCs have. Any personal assets can be used if you owe money on business debts or get sued.
3. Liability
With an LLC, members aren't personally on the hook for the company's debts or legal obligations. Your business finances are legally separate from your personal ones.
That said, I always advise clients to open a dedicated business bank account regardless. Commingling funds is one of the fastest ways to lose that liability protection — it's called "piercing the corporate veil," and it's more common than most people realize.
Sole proprietors don't get that separation. If the business owes money or gets sued, your personal assets are exposed.

4. Taxation
Both structures avoid corporate-level taxation. Instead, profits pass through to the owner's personal tax return — which keeps things simpler and often means a lower overall tax burden than a corporation would face.
What are the Advantages and Disadvantages of an LLC
Here are the advantages and disadvantages of starting an LLC:
1. Advantages
- Personal Liability Protection: Your personal assets stay separate from the business. Debts, lawsuits, and other obligations belong to the LLC — not to you personally.
- Pass-through taxation: The LLC itself doesn't pay corporate taxes. Profits flow through to members' individual returns, which keeps the tax structure clean and manageable.
- Flexible management and organization: You can run the LLC yourself or hand operations off to a hired manager. For clients who are new to running a business, I'd strongly recommend bringing in an experienced manager for at least the first year — it makes a bigger difference than most people expect.
- Less compliance requirements: Compared to corporations, LLCs have lighter compliance obligations. Most states just require an annual report and franchise tax payment.
2. Disadvantages Of An LLC
- Transfer of ownership: If a member leaves, retires, or passes away, transferring their ownership stake requires approval from all remaining members — which can slow things down.
- Limitation of existence: Depending on the state and the purpose of the company, an LLC may be set up to operate for a limited period of time.
What are the Advantages and Disadvantages of a Sole Proprietorship
Here's what a sole proprietorship gets right — and where it falls short:
1. Advantages of Sole Proprietorships
- Fewer formation requirements: Getting a sole proprietorship up and running takes minimal effort. You need an EIN, the right licenses and permits, and you're essentially done.
- Pass-through taxation: Just like an LLC, sole proprietors don't pay at the corporate level. Income shows up on your personal return.
- Simple management: One owner means no committee decisions, no approval chains, and no internal politics. Most of my business associates started as sole proprietors before eventually converting to an LLC — it's a reasonable way to get off the ground fast.
2. Disadvantages of Sole Proprietorships
- No liability protection: There's no legal separation between you and your business. If something goes wrong — a lawsuit, an unpaid debt — your personal assets are on the line. This is the one drawback that pushes most serious founders toward an LLC.
