Every dollar of legitimate business expense you track is a dollar that lowers your taxable income, and every one you fail to document is money left on the table. For a commercial leasing broker running on commission income, expense tracking is not bookkeeping busywork, it is one of the most direct levers on what you actually keep. This guide lays out the categories worth tracking, what records to hold, and points you to a tracker built to capture them as you go.
Logging expenses as they happen beats reconstructing them at tax time, every time. The downloadable expense tracker lets you record each expense with a category and deductible status from dropdowns, and it totals your spending by category and your deductible total automatically. Keep it open, log as you spend, and the work is done before tax season starts.
These are the common business expense categories for a commercial leasing broker. Whether and how much of each is deductible depends on your situation and is a question for your CPA, but these are the buckets to capture.
A deduction is only as good as its documentation. For each expense, keep the receipt or a clear record, note the business purpose, and log it promptly while you remember the context. For mileage, record the date, distance, and reason for each trip rather than estimating at year end. For client meals, note who you met and the business reason. The standard to aim for is simple: if you had to explain any single expense, you could, with a record to back it. The tracker captures exactly these fields so the documentation builds itself.
Diligent expense tracking helps you in two directions at once. It lowers your tax bill by capturing every legitimate deduction, which is the obvious benefit. Less obviously, it gives you a clear picture of what it actually costs to run your business, which sharpens your cash flow planning and your sense of how much you need each month. The expense total feeds directly into the cash flow forecast and the reserve you hold. Tracking expenses is where tax discipline and cash flow discipline meet.
Common categories include marketing, auto and mileage, software and CRM, licensing and dues, E&O insurance, professional development, office and home office, travel, 50% of client meals, phone and internet, and professional services. Deductibility depends on your situation, so confirm with your CPA. The 2026 rates and rules are in the tax guide for commercial real estate brokers.
Record each business trip as it happens, with the date, miles, route, and reason. Contemporaneous records are far stronger than year-end estimates, and mileage is a major category for field-heavy leasing brokers.
Generally no. Entertainment, such as event tickets, is generally not deductible, while business meals are generally 50% deductible (IRS Pub. 463).
It is the IRS de minimis safe harbor. If you elect it on a timely filed return, and you don't have an applicable financial statement, you can deduct items costing up to $2,500 per invoice or item instead of depreciating them (IRS).
Keep a receipt or clear record for each expense, along with the business purpose. A deduction you cannot document is one you cannot safely take, which is why logging as you go matters.
This guide and the tracker provide general organizing tools for commercial real estate brokers and are not tax advice. Deductibility depends on your situation. Confirm with a licensed CPA.
