Plain English: How Montana Realtor Taxes Actually Work

Tax rules can feel like a foreign language. Here is a simple, common-sense breakdown of how you get paid and how to save.

1Sponsoring brokers don't withhold taxes

When you close a transaction, your sponsoring broker issues your split in full. Unlike traditional employee roles where taxes are deducted from every paycheck, your split is paid at 100% gross value. Sponsoring brokers report this to the IRS as 1099 independent contractor income, meaning zero taxes have been paid on these earnings yet.

💡 Realtor Rule of Thumb: Treat only 70% of every commission check as your actual money. Open a dedicated business savings account and transfer 30% of every closing check there immediately to cover tax liabilities when estimated payments are due.

2You owe two distinct tax pots

Realtors pay self-employment tax (15.3% for Social Security and Medicare) and standard income tax. Regular employees only pay half of the FICA tax because their employer pays the other half. As a self-employed business owner, you act as both the employee and employer, meaning you pay the full 15.3% on top of normal federal income tax brackets (plus state income tax).

💡 Realtor Rule of Thumb: Track every business expense (mileage, MLS dues, lockboxes, client staging). Every $1,000 you write off reduces your taxable profit, saving you $153 in self-employment tax alone, plus federal and state income taxes.

3S-Corp election splits your income

By forming a corporate entity and electing S-Corp status, the IRS allows you to split your business profit. You pay yourself a reasonable salary under a W-2 payroll, paying the 15.3% self-employment tax only on that salary. The remaining net profit is paid to you as a shareholder distribution, which is completely free from the 15.3% self-employment tax.

💡 Realtor Rule of Thumb: S-Corp structures come with accounting overhead (running payroll, corporate tax filings). Consider electing S-Corp status once your net business profit consistently crosses $80,000 to $100,000 per year, as the tax savings will easily outpace the administrative costs.

4The Montana catch

Montana allows brokers to pay commission splits to a personal LLC, which costs just $20 per year to maintain.

💡 Realtor Rule of Thumb: The annual report is due by April 15th; file online to keep your fee at the minimum $20.
