The cleanest approach is to track each transaction as a separate line item with the gross commission, your brokerage’s split, and your net take-home amount. This gives you clear records for reconciling with your brokerage and accurate income figures for tax time.

Record every deal with key details: property address, client name, closing date, and commission breakdown. The property address acts as a unique identifier when you’re looking back at your records or matching against brokerage statements. Include both the expected and actual amounts since commissions sometimes change between contract and closing.

Most real estate agents operate on cash basis accounting, meaning you record income when the check hits your account, not when escrow closes. This is simpler and matches how you’ll file taxes as a self-employed agent. Don’t book a commission as income until you’ve actually received payment.

Track the gross commission and your net separately. If a deal pays $15,000 gross but your brokerage takes 20%, you received $12,000. Some agents only track what they deposit, but knowing the gross helps you understand your true production and whether your brokerage arrangement makes sense long-term.

Keep a running list of pending transactions. Deals in escrow represent future income, and you need visibility into what’s coming. When a deal closes and you receive payment, move it from pending to completed and record the income in your accounting software.

Reconcile against your brokerage’s statements monthly. Your broker sends commission summaries or 1099s at year end, and any mismatch becomes a problem during tax prep. Catching discrepancies monthly is easier than sorting through a full year of transactions.

Use QuickBooks or similar accounting software rather than just a spreadsheet. A spreadsheet works for tracking deals, but you need proper accounting software to categorize business expenses, generate profit and loss statements, and prepare for tax filing. The transaction details can live in a spreadsheet that feeds into your books.

Separate business expenses from commission income clearly. Marketing costs, car expenses, staging fees, lockbox dues, and MLS fees are all deductible against your commission income. The cleaner your expense tracking, the lower your tax liability.

Working with a small business accountant in the San Gabriel Valley who understands real estate makes this easier. Commission income follows patterns most small businesses don’t see: irregular payments, splits with multiple parties, and expenses that vary by transaction. A bookkeeper familiar with how agents actually work can set up systems that match your business and keep you ready for tax season without scrambling at year end.
