The IRS Is Watching: How to Legally Sidestep Self-Employment Tax

Most business owners don't realize this, but the IRS has a very specific lens for deciding who pays self-employment tax. And if you're an active member of an LLC taxed as a partnership, the default treatment is brutal: every dollar of profit is hit with 15.3 percent.

It doesn't matter that your LLC gives you limited liability. For tax purposes, you look like a general partner. And general partners pay SE tax on their distributive share. Period.

But there's a legal, time-tested way to reframe that classification without picking a fight with the IRS.

It's called the S-Corp Buffer.

And if you do it correctly—reasonable salary, clean documentation, real economic substance—you can cut self-employment tax dramatically while staying fully inside the rules.

Let's break it down.

The real problem: The IRS doesn't care about your title

The most common misconception I see is simple: "I'm an LLC member. I have limited liability. So I'm a limited partner for tax purposes."

Wrong.

The courts have been clear for decades. Renkemeyer. Castigliola. Rev. Rul. 69-184. If you materially participate, you're a general partner for tax purposes. And general partners don't get the §1402(a)(13) exclusion.

So if your LLC earns $100,000, you lose $15,300 to SE tax before income tax even enters the conversation.

If you've been wondering why your tax bill feels inflated, this is why.

The simplest fix—when you're allowed to use it

If your LLC has no ownership complications, the cleanest solution is electing to be taxed as an S-Corporation:

• You pay yourself a reasonable salary (hit by payroll taxes).
• The remaining profit passes through as S-Corp distributions (not subject to SE tax).

This works. It's established. And most solo owners stop here.

But many businesses can't use an S-Corp directly. Ownership restrictions, preferred returns, non-US investors, or a minority position can all make an entity-level S-Corp election impossible.

So you need something more flexible.

The S-Corp Buffer Strategy

This is where the workaround comes in.

Instead of owning your partnership interest directly, you form an S-Corporation and have that S-Corp own your share of the LLC.

The mechanics:

• Your S-Corp becomes the partner.
• The LLC distributes profit to the S-Corp.
• Your S-Corp pays you a reasonable salary (payroll taxes apply).
• Anything beyond your salary flows to you as S-Corp distributions—exempt from SE tax.

You still participate. You still work. But for tax purposes, you're not the partner. The S-Corp is.

And under current law, that separation matters.

One key case: Watson

In Watson v. United States, an S-Corporation owned a partnership interest in a CPA firm. The IRS challenged the shareholder's low salary. But they didn't challenge the structure itself. The passthrough income was treated as S-Corp income—not SE-taxable partnership profit.

That silence is telling. The IRS attacked compensation. Not the buffer.

But none of this works without economic substance

If your S-Corp exists only to dodge SE tax, you're inviting a Gregory v. Helvering problem.

Your S-Corp needs to:

• Operate as a real business entity
• Pay a market-based salary
• Maintain corporate formalities
• Ideally invoice or contract on your behalf

It doesn't need an office or employees. But it cannot be a shell.

Do this correctly and you've created a structure the IRS has respected for decades. Do it sloppily and you've set yourself up for recharacterization.

TL;DR

• Most LLC members are general partners for tax purposes—and pay 15.3 percent SE tax on profits.
• Electing S-Corp status works, but the entity-level election isn't always possible.
• The S-Corp Buffer lets your S-Corp own the partnership interest, turning SE-taxable income into S-Corp distributions.
• The IRS has challenged unreasonable salary, not the structure itself (Watson).
• Economic substance is non-negotiable.

If you want to run this structure correctly—and avoid the traps that trigger IRS scrutiny—make sure you're aligned on salary, compliance, and corporate formalities. The strategy is powerful, but only when executed with precision.
