How to Reduce Self-Employment Taxes as a Commercial Real Estate Broker

Income tax gets most of the attention when people talk about reducing their tax bill. Self-employment tax mostly gets ignored, which is a problem because for a broker generating $250,000 in net self-employment income, the SE tax alone can run $25,000 or more before federal income tax enters the picture.

The rate is 15.3% on the first $176,100 of net earnings in 2025, and 2.9% on everything above that. You're paying both sides of payroll tax because you are both the employer and the employee in this equation.

The good news is there are legal, well-established ways to reduce it.

The S Corp Election

Electing S corp status is the most significant self-employment tax reduction available to most brokers, and it's also the most misunderstood.

As a sole proprietor or single-member LLC, every dollar of net income is subject to SE tax. When you elect S corp status, income splits into two pieces: a W-2 salary that goes through payroll and a distribution that doesn't. Payroll taxes apply to the W-2. They don't apply to the distribution.

If your S corp nets $300,000 and you pay yourself a W-2 of $100,000, payroll taxes apply to the $100,000. The remaining $200,000 in S corp distributions bypasses that extra tax. At combined employer and employee payroll tax rates, that can represent $15,000 to $29,000 in annual savings depending on where your income falls relative to the Social Security wage base.

The IRS requires S corp owner-employees to pay themselves a reasonable salary. They will examine situations where a highly profitable S corp is paying the owner almost nothing in W-2 wages. What's reasonable depends on what the market would pay someone doing comparable work. For a broker generating $400,000 in commissions, reasonable might be $80,000 to $120,000. Set the number with a qualified CPA or financial planner, not arbitrarily low.

Retirement Account Contributions

After the S corp structure, maximizing retirement contributions is the next highest-impact tool. Every dollar into a pre-tax Solo 401k or SEP IRA reduces taxable income dollar for dollar.

In the 24% federal bracket with Utah state tax on top, a $50,000 retirement contribution could save roughly $14,000 of income taxes that year. That's separate from and on top of the SE tax reduction from the S corp structure.

The QBI Deduction

Real estate brokerage income generally qualifies for the Section 199A Qualified Business Income deduction, which allows eligible self-employed business owners to deduct up to 20% of qualified business income (the business profits after you pay yourself wages).

Something to be aware of, the deduction gets limited by W-2 wages paid. This creates a direct tension with the S corp payroll tax strategy: lower W-2 means less SE tax, but it also limits the QBI deduction. The right W-2 salary isn't purely a payroll tax question. It affects the QBI deduction too.

Running both calculations simultaneously to find the optimal W-2 is something I help with CRE brokers and their CPAs. The answer varies based on income level, state taxes, and retirement contributions.
