The S Corp Question for 2026: When Does It Still Make Sense?

You built a business that clears $300,000 or more a year. You file on Schedule C, pay the full 15.3% self-employment tax on every dollar of profit, and your preparer has never once asked whether that structure still fits. This is the most common tax problem we see in San Diego business owners who have grown past the sole proprietor stage: the structure that worked at $80,000 is quietly costing them five figures a year at $400,000.

An S corp election splits your business income into two pieces: a reasonable salary (which pays self-employment tax) and distributions (which do not). The distributions still pay income tax. They just skip the 15.3% layer. That is the entire mechanism. No loopholes, no hidden credits. Just two buckets instead of one.

The self-employment tax you did not choose

Schedule C income hits you twice: income tax and self-employment tax. The SE tax is 15.3% (12.4% for Social Security and 2.9% for Medicare) on your net profit. On $400,000 of Schedule C profit that is roughly $22,000 in SE tax alone. On $600,000 it is roughly $27,000. The Social Security portion has an annual wage base cap (most recently $176,100), and an additional 0.9% Medicare surcharge kicks in above $200,000 single or $250,000 married filing jointly. The mechanics shift slightly at each threshold, but the core pattern is the same: every dollar of profit above a reasonable salary runs through SE tax that a different structure would not charge.

How the S corp split works

Consider a business owner with $400,000 in net profit. Under an S corp they take a reasonable salary of $180,000, and the remaining $220,000 passes through as a distribution.

The salary pays the employer and employee shares of SE tax, roughly $13,700 on $180,000 (the Social Security portion caps at the wage base, so the math is not simply 15.3% across all of it). The $220,000 distribution pays zero SE tax. Compared to paying SE tax on the full $400,000 as a sole proprietor, the savings is roughly $12,000 to $15,000 a year.

That range depends on the exact wage base and where your income falls relative to the Medicare surcharge threshold. The direction is durable: the more profit above a reasonable salary, the more the election saves.

Payroll costs eat into that savings. You need a payroll service (roughly $800 to $2,000 a year), state unemployment tax, and the administrative time of running payroll. In most profitable businesses the SE tax savings still clears those costs by a wide margin.

Reasonable compensation: the number the IRS watches

The IRS calls it reasonable compensation, and it is the single most scrutinized number on an S corp return. Pay yourself a $40,000 salary on $500,000 of profit and you are not saving SE tax. You are inviting an audit.

What we do is model the right salary before filing Form 2553. We look at comparable salaries in your industry, your actual role and time commitment, and your profit history. Then we set a number that passes IRS scrutiny and leaves meaningful room for distributions. Underpaying yourself is the fastest way to lose the benefit in an audit. The IRS can reclassify distributions as wages, and the back taxes plus penalties wipe out years of savings.

When an S corp does not make sense

The election is not right for every business. Three situations where it falls apart:

Profit below $60,000 to $80,000. Below this range, the SE tax savings is too small to cover payroll costs and administrative overhead. You net more as a sole proprietor.

California S corp owners. California charges a 1.5% franchise tax on S corp net income, with an $800 minimum. On $400,000 of profit that is $6,000, a real cost that narrows the savings. We model both scenarios before recommending the election.

Owners running multiple related businesses. If you have two or three entities without coordinated structuring, an S corp election on one piece can interact poorly with the others. A holding company or multi-entity setup might serve you better. We wrote about that dynamic in The Multi-Entity Tax Setup That's Saving Business Owners $60K a Year.

For everyone else, profitable service businesses, trades, professional practices, and real estate operations, the election is worth modeling at least once.

What the process actually looks like

Form 2553 must be filed with the IRS by March 15 of the tax year the election should take effect (or any time during the preceding year). A late election is possible under some circumstances, but filing on time avoids the headache.

Once the election is approved you need:

• A separate payroll setup (Gusto, ADP, or a similar service)
• An EIN for the S corp (even if you already have one as a sole proprietor)
• State-level S corp recognition (most states accept the federal election; California and New York require a separate state election)
• Quarterly payroll filings and Form 941

The paperwork is manageable. The strategy (setting the right salary, timing the election, coordinating with other entities you own) is where a strategist adds value. A preparer fills out forms. A strategist decides which forms to file in the first place.

FAQ

What is an S corp election?

An S corp election is a tax status a business files with the IRS using Form 2553 that lets a profitable business split income into a reasonable salary (subject to self-employment tax) and distributions (not subject to self-employment tax). It is available to domestic corporations and LLCs that meet the eligibility requirements.

How much does an S corp save in self-employment tax?

For a business owner with $400,000 in net profit and a $180,000 reasonable salary, the savings is roughly $12,000 to $15,000 a year compared to paying full SE tax on all profit. The exact number depends on the Social Security wage base, the Medicare surcharge, and payroll costs.

When should a business owner elect S corp status?

When net profit is consistently above $60,000 to $80,000 and the owner provides substantial services to the business. Below that range, payroll costs eat the savings. Above it, the SE tax savings typically justifies the election.

What is reasonable compensation for an S corp?

Reasonable compensation is the salary an S corp owner must pay themselves for the services they provide. It must reflect what a third party would pay for the same work. The IRS scrutinizes this number closely, and underpaying can trigger an audit and reclassification.

Does California recognize S corp elections?

Yes, but California imposes a 1.5% franchise tax on S corp net income with an $800 minimum. This additional cost must be factored into the decision. Some other states also require a separate state-level election.

Can I convert my LLC to an S corp?

Yes. If your LLC is already taxed as a sole proprietorship or partnership, you file Form 2553 to elect S corp status. The LLC itself remains the legal entity; only the tax classification changes. You will need to set up payroll and obtain a new EIN.

The right structure depends on your actual numbers. Not what your industry average is, and not what your neighbor did. Your revenue, your role, your state. A 15-minute discovery call is enough to model whether the election works for you. Call (619) 280-2700 or email info@RoadmapTax.com.
