A $10,000 commission check rarely means $10,000 in your pocket. By the time referral fees, your brokerage split, transaction fees, business costs and taxes come out, many agents keep far less than they expect. And because nobody withholds tax from a commission check, the tax bill arrives months later. This guide walks through the numbers, and the bookkeeping habits that keep commission income under control.
How a real estate commission is split
- Gross commission income (GCI): sale price × the commission rate agreed for your side of the deal. Commissions are negotiable and vary by transaction.
- Referral fees: if another agent referred the client, their percentage usually comes off the top.
- Brokerage split: your share under your agreement, for example 70/30 or 80/20, until you reach any annual cap.
- Fees: transaction, desk, technology or franchise fees.
What is left is your net commission. It is business income, not take-home pay.
Why agents owe self-employment tax
Most licensed agents are treated as independent contractors, and brokerages report commissions on Form 1099-NEC. That means you pay self-employment tax of 15.3% on 92.35% of your net earnings (Social Security up to the annual wage base, plus Medicare), on top of federal and state income tax. Nothing is withheld, so you are responsible for paying it through the year.
Quarterly estimated taxes for agents
Estimated tax payments are generally due April 15, June 15, September 15 and January 15. Many agents use the IRS safe harbor: paying 100% of last year’s total tax through the year (110% if last year’s adjusted gross income was over $150,000) avoids an underpayment penalty even if this year’s income jumps. See our quarterly estimated taxes guide.
A simple set-aside system
- Open a separate business checking account and a separate tax savings account.
- When a commission lands, move a fixed percentage (often 25 to 35 percent, depending on your bracket and state) into tax savings the same day.
- Pay quarterly estimates from that account only.
- Review the percentage each quarter as your income and expenses change.
Deductions agents should track
| Expense | Bookkeeping tip |
|---|---|
| Vehicle and mileage | Keep a mileage log for showings, listings and client meetings. Use either the standard mileage rate or actual expenses. |
| MLS, association and license fees | Record them as dues and subscriptions. Keep the invoices. |
| Marketing and staging | Tag costs to the listing so you can see profit per deal. |
| E&O insurance, phone, software, CRM | Split any personal use of your phone. |
| Home office | Only if a space is used regularly and exclusively for business. |
The same rules apply to other commission-based professionals
Insurance agents, mortgage loan officers and independent sales reps face the same pattern: irregular commission income, no withholding and a mix of deductible costs. The set-aside system and monthly reconciliation work for all of them.
What your monthly books should show
Every closing recorded at gross with splits and fees shown separately, expenses categorized, bank and credit card accounts reconciled, and a running estimate of tax owed. With that, quarterly payments take minutes. Our real estate agent bookkeeping guide goes deeper, and our monthly bookkeeping service does it for you.
