By default, a single-member LLC is taxed the same as a sole proprietorship (Schedule C). Both pay self-employment tax on all net income. The main difference is liability protection. For tax savings, consider electing S Corporation status, which can reduce SE tax by splitting income between salary and distributions.

S Corporation Election

The Tax-Saving Option

Both sole proprietorships and single-member LLCs can elect S Corporation tax treatment to potentially save on self-employment tax.

How S Corp Taxation Works

Instead of all income being subject to SE tax:

  1. Take a Reasonable Salary → Subject to payroll taxes (FICA)
  2. Take Distributions → NOT subject to payroll taxes

S Corp Tax Savings Example

Scenario: $100,000 business income

ItemSchedule C (No S Corp)S Corp ($50K salary)
Total Income$100,000$100,000
Salary$0$50,000
Distributions$0$50,000
FICA/SE Tax$15,300$7,650
Federal Income Tax$10,312$10,312
Total Tax$25,612$17,962
Savings-$7,650

S Corp Requirements

RequirementDetails
Reasonable salaryMust pay market-rate salary before distributions
PayrollMust run payroll, file payroll taxes
Separate accountsBusiness bank account required
Tax returnForm 1120-S (separate return)
DeadlinesMarch 15 for S Corp return
State taxesMay have franchise tax

When S Corp Makes Sense

Consider S Corp if:

  • Net income > $60,000-80,000/year
  • Can justify reasonable salary
  • Willing to handle payroll
  • In business for the long term

Skip S Corp if:

  • Net income < $50,000/year
  • All income is essentially salary
  • Don’t want payroll complexity
  • Short-term side hustle

<FAQ questions={[ { question: “Can I switch from sole proprietorship to LLC?”, answer: “Yes, you can form an LLC at any time. You’ll transfer business assets to the LLC and start operating under the LLC. The LLC will be treated as a new entity for tax purposes, and you’ll file accordingly. You don’t need to close the sole proprietorship first.” }, { question: “Does an LLC reduce my taxes?”, answer: “By default, no. A single-member LLC is taxed the same as a sole proprietorship (Schedule C). Taxes are only reduced if you elect S Corporation status AND your business has sufficient income to benefit from the salary/distribution split.” }, { question: “Can I be both a sole proprietor and have an LLC?”, answer: “Yes, you can have multiple businesses with different structures. For example, you might operate a consulting practice as an LLC and a separate freelance writing business as a sole proprietorship. Each business would file its own Schedule C.” }, { question: “What’s the minimum income to justify an LLC?”, answer: “There’s no minimum income requirement for an LLC. The question is whether the liability protection and credibility justify the formation costs ($50-800) and ongoing fees ($0-800/year). For liability protection alone, even low-income businesses may benefit.” }, { question: “Do I need a lawyer to form an LLC?”, answer: “No, you can form an LLC yourself by filing Articles of Organization with your state. Services like LegalZoom or your state’s website make it straightforward. Consider a lawyer if your business is complex, has multiple members, or involves significant assets.” }, { question: “Can a sole proprietorship have employees?”, answer: “Yes, sole proprietorships can have employees. You’ll need an EIN, withhold payroll taxes, and file employment tax returns. The business is still a sole proprietorship, and you’re personally liable for payroll taxes and other obligations.” }, { question: “What happens to my LLC if I move to another state?”, answer: “You have options: (1) register your existing LLC as a foreign LLC in the new state, (2) dissolve the old LLC and form a new one in the new state, or (3) domesticate the LLC in the new state if available. Each option has tax and legal implications.” }, { question: “Can I convert my sole proprietorship to an S Corporation?”, answer: “Yes, but you must first form an entity (LLC or corporation) and then elect S Corporation status. You can’t be a sole proprietorship and S Corporation simultaneously. The entity provides the legal structure; S Corp is just a tax election.” } ]} />

Choose the Right Structure for Your Business

Both sole proprietorships and LLCs can be excellent choices depending on your situation. For most beginners, a sole proprietorship is fine to start. As income grows and liability risks increase, consider forming an LLC. When income exceeds $60,000-80,000/year, evaluate S Corporation taxation for potential tax savings.
