Bookkeeping for real estate agents: Track commissions, splits, and expenses

You closed 18 transactions last year, totaling $186,000 in gross commission volume. After your broker's split, you kept $130,200. You spent roughly $28,000 on marketing, MLS fees, licensing, vehicle costs, and client gifts. Your actual net income was around $102,000. But when your CPA asked for documentation, you handed over a shoebox of receipts, three credit card statements, and a spreadsheet you had not updated since June.

Real estate agents earn irregular income, pay significant business expenses from personal accounts, split commissions through complex brokerage arrangements, and often operate as independent contractors without the payroll infrastructure that automatically tracks income and withholding. This combination makes real estate agent bookkeeping simultaneously more important and more neglected than in almost any other profession.

The agent who tracks commissions, expenses, and net income throughout the year makes better business decisions, pays less in taxes through legitimate deductions, and avoids the February panic of reconstructing a year's worth of financial activity from memory.

Commission tracking is the revenue side

Real estate commission income is not as simple as "I sold a house and got paid." The path from closing to cash involves multiple parties, variable splits, and timing delays that must be tracked accurately.

Track gross commission earned, not just net received. When a $400,000 home closes with a 3% buyer agent commission, the gross commission is $12,000. If your brokerage split is 70/30, you receive $8,400, and the brokerage retains $3,600. Your bookkeeping should record the full $12,000 as gross income and the $3,600 brokerage split as an expense. This matters because your tax obligations and business metrics (average commission, cost ratios) should be based on gross commission, not the net check.

Record each transaction individually. Do not deposit commission checks and categorize the bank deposit as "Commission Income." Record each closing with the property address, closing date, sale price, gross commission, split percentage, net commission, and any referral fees paid. This transaction-level detail supports tax preparation, business analysis, and dispute resolution. Commissions contractually earned but not yet received are accounts receivable and should be tracked as such between closing and payment arrival.

Account for split structures that change. Many brokerages use tiered splits: 60/40 until the agent reaches a cap, then 90/10 or 100/0. Some use flat monthly desk fees plus a higher split percentage. Track which split tier applies to each transaction so you can estimate when you will hit your cap and how it will affect income for the remainder of the year.

Track referral fees paid and received. A 25% referral fee paid to another agent on a $10,000 commission reduces your gross income by $2,500. Record this as a separate expense, not as a reduction in gross commission. Referral fees paid to other agents require a 1099 at year-end if they exceed $600 to any single recipient.

Expense tracking is where agents leave money on the table

Real estate agents have significant deductible business expenses that reduce taxable income. The agent who tracks every legitimate expense pays less in taxes. The agent who loses receipts and forgets deductions overpays. For a full framework of which expenses are deductible business costs versus personal spending, the guide to billable vs non-billable expenses covers the classification logic that applies across professional services businesses.

Marketing and advertising. Website hosting, IDX fees, social media advertising, print materials, signage, open house expenses, professional photography, virtual tours, and staging costs. For most productive agents, marketing represents 10% to 20% of gross commission. On $130,000 in net commission, that is $13,000 to $26,000 in deductible expenses.

Vehicle expenses. Agents drive constantly: showings, listings, inspections, closings, networking events. You can deduct either actual vehicle expenses (gas, insurance, maintenance, depreciation) proportional to business use, or the standard mileage rate (67 cents per mile for 2024). Either method requires a contemporaneous mileage log. An agent driving 15,000 business miles annually deducts $10,050 at the standard rate. Without a log, this deduction is indefensible in an audit.

Technology and tools. CRM software, transaction management platforms, e-signature tools, cloud storage, phone and data plan (business use percentage), laptop, and tablet. These recurring costs are fully deductible.

Professional development. License renewal, continuing education courses, designation fees (CRS, ABR, GRI), NAR and local board dues, MLS fees, and conference attendance. These are ordinary and necessary business expenses.

Client-related expenses. Closing gifts, client appreciation events, and meals with clients (50% deductible for business meals). Keep receipts and note the business purpose and attendees.

Home office. If you maintain a dedicated home office space used exclusively for business, deduct either the simplified method ($5 per square foot up to 300 square feet, with a maximum of $1,500) or actual expenses proportional to the office's share of the home's total square footage.

Setting up a bookkeeping system that actually works

Most agents fail at bookkeeping not because it is complicated, but because they do not set up a system that fits their workflow.

Separate business and personal finances. Open a dedicated business checking account and business credit card. Run all business expenses through business accounts. This single step eliminates 80% of the year-end sorting problem.

Use accounting software, not spreadsheets. QuickBooks Self-Employed or QuickBooks Online Simple Start costs $10 to $30 per month and automates transaction categorization, mileage tracking, and tax estimation. Wave is free. FreshBooks works well for agents. Any of these is better than a spreadsheet you will abandon by April.

Categorize transactions weekly. Set a recurring 15-minute appointment every Friday to review and categorize the week's transactions. Categorizing 5 to 10 transactions weekly is painless. Categorizing 250 transactions in February is miserable and error-prone.

Use a mileage tracking app. MileIQ, Everlance, or the QuickBooks mileage tracker. Turn it on and forget it. The app logs business trips automatically. Manual mileage logs fail because nobody maintains them consistently.

Save digital receipts. Photograph every paper receipt with your phone and store it in a dedicated folder or directly in your accounting software. Paper receipts fade. Digital receipts do not.

Quarterly estimated taxes: The expense agents forget

Independent contractor real estate agents do not have taxes withheld from their commission checks. The IRS expects quarterly estimated tax payments (April 15, June 15, September 15, January 15) covering both income tax and self-employment tax (15.3% on net self-employment income).

An agent earning $100,000 in net self-employment income owes approximately $15,300 in self-employment tax alone, plus federal and state income tax. Failing to make quarterly estimates triggers underpayment penalties. Understanding the cash runway your commission income provides at any given point in the year is essential for setting aside enough to meet each quarterly payment without a cash crunch. For agents with highly seasonal or irregular closing schedules, the 13-week cash flow forecast provides the forward visibility to plan quarterly tax payments alongside operating expenses without surprises.

The calculation is straightforward: estimate annual net income (gross commission minus brokerage split minus business expenses), calculate self-employment tax (15.3% of 92.35% of net income), add estimated income tax, divide by 4, and pay quarterly. Your accounting software can estimate this automatically if you keep it up to date.

The annual return on 15 minutes per week

An agent who spends 15 minutes per week on bookkeeping invests approximately 13 hours per year. That investment typically produces $5,000 to $15,000 in identified deductions that would otherwise be missed, eliminates the $500 to $1,500 premium a CPA charges for reconstructing disorganized records, and prevents underpayment penalties that add 3% to 8% to the tax bill. For agents running more than 15 to 20 transactions per year, a monthly review of per-transaction profitability identifies which deal types, price ranges, and client sources generate the most margin after expenses, the same analysis that separates agents who manage their business from agents who just sell houses.

The math is simple. The discipline is what separates agents who manage their business from agents who just sell houses.

Frequently asked questions

How is a broker commission split reported for taxes?

An agent who receives commissions through a brokerage arrangement reports gross commission income (before the broker's split) as business income on Schedule C. The broker's retained portion is then deducted as a business expense on the same return. On a $12,000 gross commission with a 70/30 split, the agent reports $12,000 as gross income and deducts $3,600 as a brokerage fee, resulting in $8,400 of net revenue from that transaction before other business expenses. This gross-in, split-as-expense method ensures the agent's Schedule C reflects actual business activity rather than just the net check received. The 1099-NEC forms issued by most brokerages reflect gross commission paid to the agent, which aligns with this reporting approach.

Do real estate agents charge sales tax on commissions?

In most US states, real estate agent commissions are services and are not subject to sales tax. However, this varies by state. A handful of states have extended sales tax to certain services, and rules can differ between residential and commercial transactions. Agents operating across multiple states should confirm each state's treatment of real estate commissions with a tax professional, particularly for commercial transactions where the analysis may differ from residential sales. Agents who also charge separately for ancillary services (consulting, staging coordination billed independently) should confirm the taxability of each service category in the states where they operate.

Should a real estate agent form an LLC or S-corp for tax purposes?

Many agents operate as sole proprietors, paying both income tax and self-employment tax (15.3%) on all net earnings. At higher income levels, forming an S-corporation allows the agent to split income between salary (subject to payroll taxes) and distributions (not subject to self-employment tax), potentially reducing the self-employment tax burden. A single-member LLC provides liability protection but does not change the default tax treatment unless the LLC separately elects S-corp status. The break-even point for S-corp election is commonly cited around $40,000 to $50,000 in net self-employment income, because the costs of payroll administration, the additional tax return (Form 1120-S), and state fees often offset the tax savings below that threshold. A CPA with real estate and small business experience should model the specific numbers before making this decision.
