S-Corp Tax Savings
How the right entity election can save business owners thousands in self-employment taxes every year—and when it makes sense to make the switch.
The Self-Employment Tax Problem
If you operate a sole proprietorship or a single-member LLC, every dollar of net business profit is subject to self-employment (SE) tax—currently 15.3% on the first $168,600 of earnings (2024) and 2.9% on everything above that threshold, plus the 0.9% Additional Medicare Tax for high earners. For a business generating $200,000 in net profit, that adds up to more than $28,000 in SE tax alone, on top of your regular federal income tax.
This is the problem the S-Corp election was designed to solve. By electing S-Corp status—either by forming a new S-Corporation or by filing Form 2553 for your existing LLC—you can split your business income into two categories: reasonable salary (subject to payroll taxes) and distributions (not subject to SE tax). The result is a significant reduction in your total tax liability with no change to your actual business operations.
The S-Corp election does not create a new legal entity. Your LLC continues to operate exactly as before. The change is purely a tax classification—you are telling the IRS to treat your LLC as an S-Corporation for federal tax purposes. This distinction is important because it means you keep the liability protection and operational flexibility of your LLC while gaining the tax benefits of S-Corp treatment.
How S-Corp Savings Work: Salary vs. Distributions
Under S-Corp taxation, you pay yourself a "reasonable salary" as a W-2 employee of your own company. Payroll taxes (Social Security and Medicare) apply only to that salary. Any remaining profit above your salary is distributed to you as the shareholder—and those distributions are exempt from SE tax.
Here is a simplified example. Suppose your business nets $250,000 in profit. As a sole proprietor, the entire $250,000 is subject to SE tax. As an S-Corp, you might pay yourself a reasonable salary of $100,000 and take the remaining $150,000 as a distribution. Payroll taxes apply only to the $100,000 salary—saving you roughly $19,000 to $22,000 in self-employment taxes depending on your exact situation.
The key phrase is "reasonable salary." The IRS requires that S-Corp owner-employees pay themselves a salary that reflects what a comparable employee would earn for similar work in the same industry and geographic area. Setting your salary too low is a red flag that invites IRS scrutiny. Setting it too high eliminates the tax savings. Finding the right number requires analyzing industry compensation data, your role in the business, and your company's revenue and profitability. Our team uses IRS-accepted methodologies and third-party compensation benchmarks to establish a defensible reasonable salary for every S-Corp client.
The Qualified Business Income (QBI) Deduction
IRC Section 199A provides a deduction of up to 20% of qualified business income for pass-through entities, including S-Corporations. This deduction is taken on your personal return and can significantly reduce your effective tax rate on business income.
For S-Corp owners, the QBI deduction interacts with your reasonable salary in an important way. W-2 wages you pay yourself are not considered QBI—only the pass-through income (your share of S-Corp profits after salary) qualifies. However, if your taxable income exceeds certain thresholds ($191,950 for single filers, $383,900 for joint filers in 2024), the QBI deduction becomes subject to limitations based on W-2 wages paid and the unadjusted basis of qualified property.
This creates a planning opportunity. For high-income S-Corp owners in service businesses (which are subject to the specified service trade or business, or SSTB, phase-out), the QBI deduction may be partially or fully limited. For non-service businesses above the threshold, paying sufficient W-2 wages through the S-Corp can actually increase the allowable QBI deduction. Our team models these scenarios to find the salary and distribution split that minimizes your total federal tax—balancing SE tax savings against QBI deduction optimization.
When Should You Elect S-Corp Status?
The S-Corp election is not right for every business or every income level. Generally, the break-even point where S-Corp savings outweigh the additional costs (payroll processing, additional tax filings, and accounting complexity) is around $60,000 to $80,000 in annual net business profit. Below that threshold, the administrative costs tend to eat into any tax savings.
Other factors that influence the decision include your state's tax treatment of S-Corps (some states impose entity-level taxes or franchise fees on S-Corps), whether you have significant business losses that you need to deduct against other income (S-Corp loss deductions are limited by your basis in the company), and whether you plan to bring on investors or go public in the future (S-Corps are limited to 100 shareholders, all of whom must be U.S. citizens or residents).
The timing of your election also matters. Form 2553 must be filed by March 15 of the tax year for which you want the election to take effect—or within 75 days of forming a new entity. Late elections are possible in some cases with reasonable cause, but it is far better to plan ahead. If you are considering the S-Corp election for next year, the time to start planning is now.
S-Corp Compliance Requirements
Operating as an S-Corp comes with additional compliance obligations that you need to handle properly. You must run payroll for yourself (and any other owner-employees) on a regular schedule, withhold and remit payroll taxes, file quarterly payroll tax returns (Form 941), issue W-2s at year-end, and file an S-Corp tax return (Form 1120-S) in addition to your personal return.
You also need to maintain reasonable corporate formalities—keeping your business and personal finances separate, documenting major business decisions, and ensuring that distributions are made in proportion to ownership percentages. Failing to follow these requirements does not automatically disqualify your S-Corp status, but it can create problems during an audit.
At AE Tax Advisors, we handle all of these compliance requirements for our S-Corp clients. Our team manages payroll setup, quarterly filings, year-end reporting, and the S-Corp tax return—so you can focus on running your business while we ensure your tax structure is optimized and fully compliant.
S-Corp vs. C-Corp: Which Is Right for You?
Some business owners ask whether they should elect C-Corp status instead of S-Corp. The answer depends on your specific situation. C-Corps pay a flat 21% federal corporate tax rate, which is lower than the top individual rate of 37%. However, C-Corp profits are taxed twice—once at the corporate level and again when distributed as dividends to shareholders. This double taxation generally makes C-Corps less tax-efficient for small to mid-size businesses that distribute most of their profits to owners.
There are situations where a C-Corp makes sense—particularly for businesses that reinvest heavily in growth and do not distribute significant profits, or for companies planning to seek venture capital or go public. For most small business owners who want to minimize their personal tax burden, the S-Corp remains the more efficient choice.
Our team analyzes your income, growth plans, and distribution needs to recommend the right entity structure. In some cases, we recommend a combination—such as holding real estate in an LLC while operating the business through an S-Corp—to capture the benefits of both structures.
