If you're a business owner earning over $60,000 in profit, chances are you've heard someone mention the S-Corp election. Maybe your CPA brought it up. Maybe a friend told you they "saved a ton" by switching. But the details matter enormously — and getting this decision wrong can cost you more than getting it right would save.

The LLC vs S-Corp question isn't really about choosing between two entity types. An LLC is a legal structure. The S-Corp is a tax election. You can be an LLC that elects S-Corp taxation. Understanding that distinction is the first step toward making the right call.

How LLCs Are Taxed by Default

A single-member LLC is treated as a disregarded entity by the IRS. All business income flows through to your personal return on Schedule C. A multi-member LLC is taxed as a partnership. In both cases, the full net profit is subject to self-employment tax — that's the 15.3% combination of Social Security (12.4%) and Medicare (2.9%) taxes.

On $200,000 in net profit, that self-employment tax alone is roughly $28,000. And here's what many business owners miss: that's on top of your regular income tax. The self-employment tax is calculated separately, and it hits every dollar of profit regardless of how much you actually take out of the business.

How S-Corp Taxation Changes the Math

When you elect S-Corp status, you split your business income into two categories: salary (W-2 wages you pay yourself) and distributions (profit you take out after salary). Only the salary portion is subject to payroll taxes. The distributions pass through to your personal return as ordinary income but are not subject to self-employment tax.

Using the same $200,000 profit example: if you set a reasonable salary at $80,000, only that $80,000 is subject to payroll taxes (~$12,240). The remaining $120,000 in distributions avoids the 15.3% hit entirely. That's roughly $15,700 in annual tax savings from the entity election alone.

The "Reasonable Salary" Requirement

The IRS requires S-Corp shareholders who perform services to pay themselves a reasonable salary. This is the single most misunderstood rule in S-Corp taxation. You cannot pay yourself $20,000 and take $180,000 as distributions. The IRS will reclassify the distributions as wages, assess back payroll taxes, and add penalties.

What counts as "reasonable" depends on your industry, role, experience, hours worked, and what comparable positions pay in your market. We typically benchmark against Bureau of Labor Statistics data and industry salary surveys. For most business owners we work with, reasonable salary falls between 35% and 50% of net business income — but this varies case by case.

When to Make the S-Corp Election

Timing matters. The S-Corp election makes sense when your business consistently generates enough profit that the self-employment tax savings exceed the additional costs of running an S-Corp. Those costs include:

  • Payroll processing: You must run formal payroll with withholding, quarterly filings, and W-2s
  • Separate tax return: S-Corps file Form 1120-S, which is more complex than a Schedule C
  • Accounting overhead: More rigorous bookkeeping requirements for shareholder basis tracking
  • State-level fees: Some states impose franchise taxes or minimum fees on S-Corps

As a general threshold, if your net business profit is consistently above $60,000 to $80,000 per year, the S-Corp election typically starts making financial sense. Below that, the additional administrative costs often eat into or exceed the tax savings. This is exactly the kind of analysis we perform as part of our entity structuring service — modeling the actual dollar impact before you make any changes.

Common S-Corp Mistakes

Electing Too Early

A startup doing $40,000 in profit doesn't need S-Corp taxation. The savings are minimal, and the added compliance cost and complexity can actually result in a net loss. Wait until the numbers justify it.

Not Paying Salary at All

We see this more than you'd think. A business owner elects S-Corp status, takes all income as distributions, and pays zero salary. This is an IRS audit magnet. If you're doing meaningful work in your business, you must be on payroll. Period.

Setting Salary Too Low

Paying yourself $30,000 when you're running a $500,000 business signals to the IRS that you're gaming the system. The goal is defensible optimization, not aggressive avoidance. We help clients find the number that maximizes savings while staying well within IRS guidelines.

Ignoring State Tax Implications

Some states (like California) impose a minimum franchise tax on S-Corps. Others don't recognize the S-Corp election at all for state tax purposes. Before you file Form 2553, you need to understand how your state treats S-Corps — and whether the federal savings outweigh any state-level costs.

S-Corp Within a Larger Strategy

Entity structure is never a standalone decision. It's one piece of a broader tax strategy that includes retirement planning, income timing, deduction optimization, and wealth integration. The S-Corp election might save you $20,000 in self-employment tax — but pairing it with a defined benefit plan could save you $100,000 more.

That's the difference between compliance-level tax work and real strategy. Your entity structure should be evaluated within the context of your full financial picture — not in isolation. Our entity structure analysis evaluates exactly that: how your business structure interacts with every other tax lever available to you.

The Bottom Line

The S-Corp election is one of the most effective tax tools available to profitable small business owners. But it requires proper implementation: correct salary levels, formal payroll, accurate bookkeeping, and a clear understanding of your state's rules. Done right, it can save you tens of thousands annually. Done wrong, it creates liability.

If you're not sure whether your current structure is optimized — or if you're still operating as a default LLC — that's worth examining. The difference between the right structure and the wrong one often compounds year after year.
