S-Corp vs LLC Guide

The real differences between an S-Corp and an LLC — and how to decide which structure (or combination) is right for your business.

The Key Difference Between S-Corp and LLC

This is where most people get confused: an LLC and an S-Corp are not the same type of thing. An LLC is a state-level legal structure. An S-Corp is a federal tax election. They operate in different lanes.

This means you can have an LLC that is taxed as an S-Corp — which is actually the most common setup for creators and freelancers who want the best of both worlds:

  • The legal simplicity and asset protection of an LLC
  • The payroll tax savings of S-Corp treatment

So the question isn't always "S-Corp OR LLC" — it's often "LLC with or without S-Corp tax election."

LLC: Legal Protection with Tax Simplicity

A standard LLC (taxed as a sole proprietor or partnership by default) offers:

  • Personal liability protection: Business debts and lawsuits generally can't touch your personal assets.
  • Simple tax filing: Income passes through to your personal return. No separate corporate tax return required.
  • Minimal formalities: No board of directors, no annual meetings, fewer compliance requirements than a corporation.
  • Flexible ownership: Members can be individuals, corporations, other LLCs, or foreign nationals.

The drawback: All net profits are subject to 15.3% self-employment tax, which can be a significant cost as your income grows.

S-Corp: Tax Savings with More Structure

An LLC that has elected S-Corp tax treatment adds a powerful tax advantage:

  • You split your income between a salary and distributions
  • Only the salary portion is subject to payroll taxes (Social Security + Medicare)
  • Distributions are not subject to self-employment tax

The tradeoff: More compliance. You must run payroll, file quarterly payroll tax deposits, and submit an annual Form 1120-S in addition to your personal return. You also need to pay yourself a "reasonable salary" — the IRS scrutinizes S-Corp owners who take artificially low salaries to minimize payroll taxes.

When it makes sense: When net profit consistently exceeds $40,000–$50,000 per year, the SE tax savings typically outweigh the added compliance cost.

Which Is Right for You?

Here's a simple framework:

  • Net income under $40k/year: A standard LLC formation is usually the right choice. Simple, low-cost, minimal compliance.
  • Net income $40k–$80k/year: Run the numbers. An S-Corp election may save you more than it costs — especially if you already have a bookkeeping system in place.
  • Net income above $80k/year: An LLC taxed as an S-Corp is almost always the smart move. The tax savings are significant and the compliance costs are manageable with the right tools.

Frequently Asked Questions

Should I have an LLC or S-Corp?

These aren't mutually exclusive. Most small business owners form an LLC first, then elect S-Corp tax treatment when their income reaches $40,000–$50,000+ net per year. This gives you liability protection (LLC) plus payroll tax savings (S-Corp).

What are the tax differences between LLC and S-Corp?

A standard LLC pays 15.3% self-employment tax on all net profits. An S-Corp allows you to split income between salary and distributions — only the salary is subject to payroll taxes, which can save thousands per year.

Can an LLC be an S-Corp?

Yes. An LLC can elect to be taxed as an S-Corporation by filing IRS Form 2553. The LLC remains an LLC at the state level for legal purposes but is treated as an S-Corp for federal tax purposes.

How much does it cost to convert an LLC to an S-Corp?

There's no state filing fee to make the S-Corp tax election — you just file Form 2553 with the IRS. The main ongoing costs are payroll processing and potentially a bookkeeper or accountant to handle the added compliance. Otto provides both at an affordable monthly rate.

What are the downsides of an S-Corp compared to an LLC?

S-Corps require more compliance: running payroll, quarterly payroll tax filings, and an annual corporate tax return. They also restrict shareholders to US citizens/residents and limit you to one class of stock. For many creators, Otto makes these requirements manageable and the tax savings far exceed the additional work.
