S-Corp Election: How to Cut Self-Employment Taxes by $10K–$30K

If you're running a profitable business as a sole proprietor or single-member LLC, you're likely paying more in taxes than you need to. Not because of anything you did wrong — but because of a structural decision you haven't made yet.

An S-Corporation election is one of the most powerful and underused tax strategies available to small business owners. Done correctly, it can save you between $10,000 and $30,000 per year in self-employment taxes alone.

Here's exactly how it works.

When you operate as a sole proprietor or single-member LLC, the IRS treats your entire net profit as self-employment income. That means you pay:

• 15.3% self-employment tax on the first $168,600 of net earnings (2024)
• 2.9% Medicare tax on everything above that threshold

On $200,000 of net profit, that's roughly $25,000–$28,000 in SE tax — before you even get to income tax.

Most business owners accept this as the cost of doing business. It doesn't have to be.

When you elect S-Corp status, your business income is split into two buckets:

1. Reasonable salary — subject to payroll taxes (Social Security + Medicare)
2. Distributions — passed through to you as a shareholder, NOT subject to self-employment tax

The key insight: only your salary is subject to payroll taxes. Distributions are not.

Say your business nets $200,000 per year. As a sole proprietor, you pay SE tax on all $200,000.

With an S-Corp election, you pay yourself a reasonable salary of $80,000 and take the remaining $120,000 as a distribution.

• Payroll taxes apply to $80,000 → roughly $12,240
• No SE tax on the $120,000 distribution

Net savings: approximately $13,000–$15,000 per year.

At higher income levels, the savings compound significantly.

The IRS requires S-Corp owner-employees to pay themselves a "reasonable salary" — meaning compensation comparable to what you'd pay someone else to do your job.

This is where business owners sometimes get into trouble. Setting your salary too low is a red flag that can trigger an audit. Setting it appropriately protects you and maximizes your savings.

Factors the IRS considers include:

• Your industry and role
• Hours worked
• Revenue generated
• What comparable positions pay in your market

A good rule of thumb: your salary should represent the market rate for your specific function in the business.

S-Corp elections come with added costs — payroll processing, additional tax filings (Form 1120-S), and potentially a payroll service. These typically run $1,500–$3,000 per year.

That means the strategy generally makes sense when your net profit exceeds $40,000–$50,000 per year. Below that threshold, the savings may not outweigh the administrative costs.

Above $80,000 in net profit, the math almost always works in your favor.

To elect S-Corp status, you file Form 2553 with the IRS. The timing matters:

• For a new business, you have 75 days from formation to elect for the current tax year
• For an existing business, the election must be filed by March 15 to take effect for the current calendar year
• Late elections are sometimes granted, but require a reasonable cause explanation

You can elect S-Corp status as either a corporation or an LLC. Most small businesses elect as an LLC taxed as an S-Corp — this gives you the liability protection of an LLC with the tax benefits of an S-Corp.

Once your S-Corp election is in place, you'll need to:

• Run payroll for yourself (at minimum quarterly, ideally monthly)
• File Form 1120-S annually (the S-Corp tax return)
• Issue yourself a W-2 at year-end
• Track distributions separately from salary

This is more administrative work than a sole proprietorship — but the tax savings typically justify it many times over.

Waiting too long. Many business owners don't discover this strategy until they've already overpaid for years. If your business is profitable, this conversation should happen now.

Setting salary too low. An unreasonably low salary is the most common S-Corp audit trigger. Work with a tax advisor to set a defensible number.

Skipping payroll. Some owners elect S-Corp status but don't actually run payroll. This creates serious compliance issues. The salary must be paid through a proper payroll system.

Ignoring state taxes. Some states don't recognize S-Corp elections, or impose their own franchise taxes on S-Corps. Your advisor should model the full picture, including state-level impact.

The S-Corp election is one of the most impactful tax moves available to profitable small business owners — but it's not right for everyone. The decision depends on your income level, business structure, state of operation, and long-term plans.

If your business is generating $80,000 or more in net profit, it's worth a dedicated conversation with a tax advisor to model your specific numbers.
