Income is lumpy and unpredictable. Expenses are scattered across categories that don’t exist for normal businesses — MLS dues, lockbox fees, broker splits, signs and showings. Mileage adds up to one of the largest deductions of the year, and most agents leave money on the table because they didn’t track it. And nothing is withheld from a commission check, which means tax season can be brutal for agents who didn’t plan for it.
Real estate agent bookkeeping doesn’t need to be complicated, but it does need to be specific to how the business actually works. Here are six categories every agent should be tracking.
1. Commission income (and how it’s reported)
The first thing to get right: how commission income hits your books. Most agents receive their commissions through their broker, with the broker’s split already taken out before the check is cut.
What to track:
- Gross commission earned on each transaction (the full commission before any split)
- Broker split taken out by the brokerage
- Net commission paid to you (what actually hit your account)
Why all three matter: at year-end, your 1099-NEC from the brokerage typically shows your net commission income. But the gross/split split affects how you analyze your business — knowing what percentage you’re keeping after your broker, what your average transaction value looks like, and whether moving to a different brokerage would change your math.
If you also earn referral fees, bonuses, or sign-on incentives, track those separately too. They’re all income, but knowing where the money is coming from helps you focus where it’s working.
2. Mileage
Mileage is the single biggest deduction most real estate agents miss — and the easiest one to capture if you do it consistently.
For 2025, the IRS standard mileage rate is 67 cents per mile for business use. (This rate adjusts annually — check the current year’s rate.) For an agent driving 15,000 business miles in a year, that’s a $10,000+ deduction.
What counts as business mileage for an agent:
- Driving to showings
- Property previews
- Client meetings
- Closings
- Office visits
- Continuing education classes
- Bank, post office, supply runs for the business
What does not count: commuting from home to a regular office (with some exceptions for home-office-based agents).
The IRS requires contemporaneous mileage logs — meaning you tracked the miles when they happened, not reconstructed at tax time. Use a mileage-tracking app (MileIQ, Stride, Everlance, or similar) that runs in the background. Reconstructed mileage logs survive audits less often than properly logged ones.
3. Marketing and lead generation expenses
Marketing is one of the biggest variable expenses for most agents — and one of the most miscategorized. Track these as separate sub-categories rather than lumping under one big “Marketing” line:
- Online ads (Zillow, Realtor.com, Facebook, Google)
- Print materials (postcards, business cards, brochures, signs)
- CRM and lead-gen software
- Professional photography and videography
- Staging costs
- Open house expenses
- Website and domain hosting
- Social media management
The separation matters for two reasons. First, it tells you which marketing channels are actually generating leads vs. just burning cash. Second, some of these are deductible in different categories — professional services vs. supplies vs. subscription software — and clean categorization speeds up tax prep.
4. Professional fees and dues
Real estate is a fee-heavy profession. Most agents underestimate how much they’re spending here annually until they total it up. Common items:
- Brokerage fees (desk fees, transaction fees, technology fees)
- MLS dues
- NAR, state, and local Realtor association dues
- Lockbox fees
- Errors & Omissions (E&O) insurance
- License renewal fees
- Continuing education (mandatory hours and elective designations)
- Professional designation costs (CRS, GRI, ABR, etc.)
These are all deductible business expenses. Track them as they happen, not all at once at tax time when half the receipts have disappeared. (More on what records to keep →)
5. Home office and technology
Most real estate agents qualify for a home office deduction — you work from home at least part of the time, and a portion of your home is dedicated to business use.
Two ways to calculate it:
- Simplified method: $5 per square foot of dedicated home office space, up to 300 square feet (max $1,500 deduction)
- Actual expense method: percentage of home expenses (utilities, mortgage interest, insurance, repairs) based on the square footage ratio
The simplified method is easier; the actual method usually gives a larger deduction if you actually track the underlying expenses cleanly.
Beyond home office, track technology and equipment:
- Computer, monitor, printer (used for the business)
- Phone (business portion if shared)
- Software subscriptions
- Cloud storage
- Office supplies
A note on the home office deduction: the IRS does scrutinize it, particularly for agents who claim a large portion of their home as office space. The space needs to be used regularly and exclusively for business — not the kitchen table.
6. Quarterly estimated taxes
This is the one most new agents get blindsided by. As a 1099 earner, no taxes are withheld from your commission checks. You’re responsible for paying your own federal income tax and self-employment tax — quarterly, throughout the year.
Quarterly estimated tax due dates are typically April 15, June 15, September 15, and January 15 of the following year. Underpayment can trigger penalties, even if you pay everything you owe at year-end.
A common rule of thumb: set aside 25–30% of every commission check in a separate savings account, then make quarterly payments out of it. Many agents work with their bookkeeper or CPA to estimate quarterly amounts based on actual income year-to-date, which is more accurate than a flat percentage.
This is one of the biggest reasons real estate agents benefit from monthly bookkeeping rather than annual: knowing your net income each month makes quarterly tax planning realistic instead of guesswork.
Common mistakes
The patterns we see most often with agent bookkeeping:
- Not tracking mileage in real time
- Mixing personal and business expenses on the same card (especially gas and meals)
- Categorizing everything as “marketing” when it could be split into more specific deductions
- Forgetting quarterly estimated taxes until the year-end tax bill
- Treating each transaction’s expenses individually instead of building a system that tracks them
- No separation between brokerage-side and agent-side fees in the books
Most of these compound over time. An agent who ignores mileage for three years isn’t behind by one year’s worth of deduction — they’ve already lost it. The IRS doesn’t allow retroactive reconstruction without contemporaneous records.
Frequently asked questions
Yes. Even though most agents operate as sole proprietors (and the IRS treats you and your business as the same entity for tax purposes), a separate business account makes bookkeeping dramatically cleaner. Deposits from the brokerage hit one account; business expenses go out from the same account; personal stuff stays separate.
In nearly all cases, 1099. Real estate agents are statutorily classified as independent contractors under federal tax law when they meet specific conditions (most do). That means no payroll withholding, no employer-paid benefits, and full responsibility for your own taxes. (More on the 1099 side →)
This is a CPA question, not a bookkeeper one — but a quick frame: an LLC gives you liability protection but doesn’t change your tax situation (you’re still a sole prop for tax purposes unless you elect otherwise). An S-corp election can save self-employment tax once your net income is high enough to justify the added cost of payroll and tax filing. Many agents make this election once their net commissions consistently clear $80–100k+, but the threshold depends on your situation.
Yes, but with limits. The IRS caps deductible business gifts at $25 per recipient per year. A $200 closing gift is fine to give — but only $25 is deductible. Many agents track these expenses anyway because the full amount affects their actual cash flow, even if the deduction is capped.
Where to start
If your bookkeeping consists of a year-end pile of receipts and a frantic call to your CPA in March, there’s a cleaner way to run it — one that captures the mileage, the dues, the marketing, the quarterly tax planning, and the home office without it eating your evenings.
