Short answer

A $12,000 commission check looks large. After broker split, brokerage fees, self-employment tax (15.3%), state income tax, and business expenses, the net may be under $4,000. Real estate agents need to model their actual take-home from every deal, save 25-30% for taxes, and treat the Solo 401(k) as the primary retirement vehicle.

Section 1 · The commission math

FROM $10,000 GROSS COMMISSION
  • Gross commission on a $400,000 home at 2.5%: $10,000.
  • After broker split (50%): $5,000.
  • After self-employment tax (15.3% on 92.35% of the $5,000): deduct approximately $706 ×DON'T TRUST, VERIFYClaim: Self-employment tax is 15.3% (12.4% Social Security up to wage base + 2.9% Medicare).Verify at: IRS SE tax ↗ Source 1 in the list belowHalf of SE tax is deductible above-the-line; the rate is on net earnings of 92.35% of self-employment income..
  • After estimated income tax (22% bracket): deduct approximately $1,100.
  • After business expenses (MLS, E&O, marketing, vehicle): deduct approximately $300-$500.
  • Net to agent: approximately $2,694 to $2,894 from a $10,000 gross commission.

The $10,000 gross commission shrinks at every step, and the broker split alone takes half before any tax. SE tax, income tax and expenses then leave the agent approximately $2,694 to $2,894. The last bar assumes $500 of expenses; the tick marks the net if expenses are $300.

This math is why most agents need to close many transactions to replace a W-2 income. Model your actual take-home from every deal before lifestyle inflationinflationA general increase in prices over time, meaning each dollar buys less than it did before.Full definition.

Section 2 · Business structure

Most agents work as sole proprietors (Schedule C) or under an LLC.

S-Corp election

Above about $40,000 to $60,000 of net commission income ($80,000+ in California), an S-Corp election can reduce self-employment tax. See LLC vs S-Corp: When the Tax Switch Pays Off for the break-even math.

Deductible business expenses

  • MLS membership fees
  • E&O (Errors and Omissions) insurance
  • Vehicle (business miles at IRS standard mileage rate, or actual expenses) ×DON'T TRUST, VERIFYClaim: The IRS publishes a standard mileage rate annually for business-use vehicle deductions.Verify at: IRS Standard Mileage Rates ↗ Source 2 in the list belowThe 2025 rate was 70 cents/mile. Verify the current year before filing.
  • Marketing and advertising
  • Home office (dedicated space)
  • Professional development and continuing education
  • Phone and technology (business portion)

Section 3 · Cash flow management

The feast-or-famine cycle: deals close in batches, not monthly. A spring rush may produce 3 closings in one month, then nothing for 6 weeks.

The system that works

  1. All commissions into a business checking account.
  2. Transfer a fixed "salary" to personal checking monthly. Same amount regardless of deals closed.
  3. In good months, the business buffer grows. In slow months, the buffer covers.
  4. Tax account: 25-30% of every commission into a dedicated savings account for quarterly estimated taxes.

Quarterly estimated taxes

Due April 15, June 15, September 15, January 15 of the following year. Safe harbor: pay 100% of prior year's tax liability (110% if AGIAdjusted Gross Income (AGI)Your total income minus certain deductions, used to calculate your tax bill.Full definition over $150,000) to avoid penalties.

Section 4 · Retirement accounts

Solo 401(k)

As a self-employed agent, a Solo 401(k) allows up to $72,000 in total contributions in 2026. The employer contribution (up to 20% of net self-employment income after half of SE tax) is deductible, reducing income tax but not SE tax. See Solo 401(k): The Self-Employed Power Account.

SEP IRA

Simpler but less powerful than Solo 401(k). No employee contribution side, only the employer side. Still significant: up to 20% of net SE income after half of SE tax.

Health insurance

100% of health-insurance premiums are deductible above-the-line for self-employed agents with no other employer coverage. See health insurance basics.
