Realtors typically work as independent contractors, which means your brokerage doesn’t withhold taxes from commissions. Instead, you’re responsible for paying self-employment tax yourself. This catches many new agents off guard when they see their first tax bill.

Self-employment tax covers Social Security and Medicare at a combined rate of 15.3% on your net self-employment income. That breaks down to 12.4% for Social Security (up to the annual wage base) and 2.9% for Medicare on all earnings. If you earn above $200,000 as a single filer, you’ll also owe an additional 0.9% Medicare tax on income above that threshold.

The IRS expects you to pay taxes as you earn income, not just at year end. Quarterly estimated payments are due in April, June, September, and January. Miss these deadlines and you’ll face underpayment penalties on top of your tax bill. Once you’re earning consistent commission income, quarterly payments should become part of your routine.

Your self-employment tax is calculated on net income after deductions. Every legitimate business expense directly reduces what you owe. Common real estate professional deductions include MLS fees, lockbox fees, marketing costs, mileage to showings, client gifts, continuing education, professional photography, staging costs, and association dues. The more deductions you document, the lower your SE tax base.

One strategy to significantly reduce self-employment tax is electing S Corp status. As an S Corp, you pay yourself a reasonable salary (which incurs payroll taxes) and take remaining profits as distributions (which avoid SE tax). If you’re earning $80,000 net as a sole proprietor, you’re paying SE tax on all of it. As an S Corp with a $50,000 salary, you only pay payroll taxes on that amount. The $30,000 distribution is subject to income tax but not self-employment tax. That’s roughly $4,500 in SE tax savings.

S Corp isn’t right for everyone. There are additional costs including payroll processing, a separate business tax return, and more detailed bookkeeping. Generally it makes sense once net income consistently exceeds $50,000 to $60,000 annually. Below that threshold, the savings may not justify the extra complexity.

Retirement contributions also reduce your tax burden. A SEP IRA lets you contribute up to 25% of net self-employment income, and those contributions are deductible. A Solo 401k offers even more flexibility. Both reduce taxable income and help build long-term wealth.

The mistake most realtors make is not tracking deductions throughout the year. You remember the big marketing spend but forget the mileage to that showing forty miles away, the client lunch, or the lockbox batteries. By tax time, you’ve lost hundreds in deductions because there’s no documentation.

Working with Treasure Valley tax professionals who understand real estate helps you capture every deduction and plan quarterly payments accurately. A mid-year check-in can identify whether S Corp election makes sense for your situation before another year passes with higher SE taxes than necessary.
