S-Corp Elections: The Window You Don't Know You're Missing

We learned about the S-corp election from an accountant during our second year of operation. The election would have changed our self-employment tax calculation starting from the first year of business. We were in year two. The standard window had closed.

We filed a late election with a reasonable cause statement. The IRS accepted it. We got lucky. The reasonable cause was real, but the IRS accepts late elections selectively, and we did not know at the time whether ours would go through.

None of this would have been necessary if someone had explained what the election was, and when it had to happen, before the window closed.

What the S-corp election actually does

An S-corp is not a type of entity. It is a tax classification. An LLC can elect to be taxed as an S-corp. A corporation can elect S-corp status. The election changes how the business's income flows to the owner for self-employment tax purposes.

Without the S-corp election, the owner of a single-member LLC pays self-employment tax on all of the business's net income. Self-employment tax is 15.3% on the first $168,600 of net earnings (the figure changes annually) and 2.9% above that threshold. That is a significant tax on every dollar of profit.

With the S-corp election, the owner is required to pay themselves a reasonable salary. Payroll taxes apply to the salary. The remaining profit, the amount above the salary, passes through to the owner as a distribution and is not subject to self-employment tax. On a business netting $200,000 per year with a reasonable salary of $100,000, the savings on the distribution portion can be meaningful.

The tradeoff is complexity. An S-corp requires payroll for the owner, a separate payroll tax account, quarterly payroll filings, and an additional layer of compliance. The question is whether the tax savings exceed the compliance costs, which typically include an accountant's fee that goes up when you add payroll.

When the election makes economic sense

Estimate your expected net profit. Set a reasonable salary (the IRS requires this to be genuine, not artificially low). The self-employment tax savings on the distribution amount is the gain. Subtract the additional accounting and payroll processing cost. If the number is positive and material, the election is worth making.

At $80,000 of net profit, the math often does not work. The savings are modest and the compliance costs consume them. At $150,000 and above, the election generally makes sense. The crossover point depends on your accountant's fees and your payroll processing costs, which is why running the calculation with a CPA who knows your numbers is worth doing before you decide.

When the deadline falls

For a new LLC, the S-corp election is made by filing IRS Form 2553. The election must be filed no later than two months and fifteen days after the beginning of the tax year in which you want it to take effect. For a company formed on January 1, that deadline is March 15. For a company formed on July 1, the election can be filed any time before the end of that tax year and will take effect the following year.

A late election can be made with a statement explaining reasonable cause for the delay. The IRS grants these, but not automatically and not always. The safe approach is to make the election during the formation process, before the window closes, if you have reason to believe the election will be beneficial. You can always revoke it later. You cannot always file it late.

The conversation to have with your accountant is not "should I make an S-corp election someday" but "given my projected income in year one, should I make this election now, and if so, when is the deadline." That conversation, early, is the one we did not have.
