LLC vs sole proprietorship: when forming a company is worth it

Most small businesses start as sole proprietorships without deciding to, simply by starting to trade. The question is when forming an LLC starts to pay for itself. This guide sets out the real differences, which are fewer than people expect for tax and larger than they expect for risk.

Short answer

An LLC vs sole proprietorship comparison comes down to liability and cost. Both are taxed the same way by default. A sole proprietorship costs nothing to set up, but you are personally liable for every business debt. An LLC costs a state fee and usually a yearly charge, and keeps business debts and most claims away from your personal assets.

Does an LLC save tax?

Not by default. A single-member LLC is disregarded for federal income tax, so it is taxed exactly like a sole proprietorship: profit on Schedule C, self-employment tax on Schedule SE. The tax difference only appears if the LLC elects S corporation status, which can reduce payroll taxes once profit is high and steady. For the full picture, see sole proprietor taxes. See when an S corp election saves tax.

What does the LLC protect?

A sole proprietor is personally responsible for everything the business owes: supplier bills, leases, loans and legal claims. An LLC generally limits those to the LLC's own assets. Two limits apply: you remain personally liable for your own negligence or professional errors, and for anything you guarantee personally. The protection also depends on keeping the LLC separate, with its own bank account and no personal spending through it.

What does the LLC cost?

A one-off state filing fee and, in most states, a yearly fee or tax. Examples: Wyoming charges $100 to form and at least $60 a year, Florida $125 and $138.75 a year, and California $70 plus an $800 minimum annual tax. New Mexico charges $50 and nothing yearly. Add a registered agent if you do not use your own address in the state. See how much an LLC costs.

When is the switch worth it?

  • You sign contracts, leases or supplier agreements where a dispute could lead to a large claim.
  • You sell physical products, especially ones that could cause harm.
  • You hire staff or subcontractors.
  • Profit is reaching the level where S corporation status could pay off.
  • You bring in a partner, which would otherwise create a general partnership with shared unlimited liability.

It is often not worth it yet when income is small and occasional, and the main risk is your own professional work, which insurance covers better. See do freelancers need an LLC.

How do you switch?

  1. Form the LLC

    See how to start an LLC.

  2. Sort out the tax number

    Decide whether the LLC needs its own EIN, for example because it will have employees or open a bank account. See what an EIN is.

  3. Open a business bank account in the LLC's name

    And stop using the old one for business.

  4. Move contracts, licenses and platforms

    Clients, suppliers, payment platforms and marketplaces should deal with the LLC from the switch date.

  5. Keep records by date

    So that income and expenses before and after the switch are clear in the books.

Ready to move from sole proprietor to LLC?

We form the LLC, move your bank and tax details across, and make sure contracts and platforms are updated in the company's name.

Questions people ask

Is an LLC better than a sole proprietorship?

For liability protection, yes. For tax, they are the same by default. Whether it is better overall depends on your risk and on whether the yearly cost is worth that protection.

Does an LLC pay less tax than a sole proprietor?

Not by default. Savings come only if the LLC elects S corporation status and profit is high enough.

Can a sole proprietor be sued personally?

Yes. A sole proprietor is personally liable for all business debts and claims.

How do I convert my sole proprietorship to an LLC?

Form the LLC with a state, set up its tax number and bank account, and move contracts, licenses and platforms to the LLC from a set date.
