The S-corp election gets recommended constantly, and for good reason — it can meaningfully reduce self-employment tax for profitable businesses. But it’s not automatically the right move at every revenue level, and the wrong timing can cost more than it saves.

What Actually Changes With an S-Corp Election

As a sole proprietor or single-member LLC, all of your business profit is subject to self-employment tax. With an S-corp election, you pay yourself a “reasonable salary” through payroll — subject to payroll taxes — and take the remaining profit as a distribution, which isn’t subject to self-employment tax at all.

The Math Only Works Past a Certain Profit Level

The S-corp structure introduces real costs: payroll processing, additional tax filings, and more administrative complexity. Below roughly $60,000–$80,000 in annual net profit, those added costs often outweigh the self-employment tax savings. The election tends to start paying off clearly once net profit consistently exceeds that range.

“Reasonable Salary” Isn’t Optional

The IRS requires that the salary you pay yourself be reasonable for the work performed, based on what someone in a comparable role would earn. Setting the salary too low to maximize distributions is one of the most common audit triggers for S-corps — the savings only hold up if the salary is defensible.

The Election Has a Deadline

To apply for the current tax year, the S-corp election generally needs to be filed within two months and fifteen days of the start of that tax year, or by the deadline for the prior tax year if switching mid-year in certain circumstances. Missing the window usually means waiting until the following year to make the switch.

It’s Not a One-Time Decision

A structure that made sense at $150,000 in revenue might not be optimal at $600,000, and the right salary-to-distribution ratio shifts as profit grows. Revisiting the numbers annually — not just electing once and forgetting about it — is where the real ongoing savings come from.

The Bottom Line

An S-corp election can be one of the highest-value tax planning moves available to a growing business, but only when the profit level supports it and the salary is set correctly. If nobody has run the actual numbers for your specific situation, that’s the conversation worth having before making the switch.
