Quick answer: You need four things: a separate business bank account and card, an app that tracks your mileage automatically, a place to put receipts, and thirty minutes a month to categorize what came through. That’s the whole system. You do not need enterprise accounting software, and you do not need to touch it daily.
Everything else in this series — the vehicle deduction, the deductions checklist, quarterly payments, QBI — depends on having numbers you can trust. This is how you get them without it taking over your life.
I teach continuing education classes on this for agents, brokerage offices, and the Miami Realtor Association across South Florida. Bookkeeping is the least glamorous thing I cover and the one that determines whether everything else works.
Why agents’ books fall apart
Three reasons, and none of them are laziness.
The income is lumpy. Nothing for six weeks, then three closings. That makes it hard to build a routine around, because there’s no rhythm to attach one to.
The business and the personal blur. Your car is your office. Your phone is your everything. You buy a client gift and groceries in the same trip. Without a deliberate separation, every transaction becomes a judgment call you’ll have to make again in April.
The paperwork arrives sideways. Your brokerage sends a 1099 that may report gross commission before splits and fees came out. If you record only what hit your bank account, your income won’t match what the IRS was told — and that mismatch generates letters.
Step one: separate the money
This is the highest-leverage thing on the list, and most agents who struggle with their books haven’t done it.
Open a business checking account. Get a business card. Run every dollar of commission income into that account and every business expense out of it. Pay yourself by transferring to your personal account.
That single change does most of the work. Your bank statement becomes your ledger. The question “was this business?” mostly disappears, because the account answers it. And if you’re ever examined, a clean separation is the difference between a straightforward review and a forensic reconstruction of your personal spending.
You don’t need a fancy business account. Any bank will do. What matters is that it exists and that you’re disciplined about which card you reach for.
Step two: track mileage as you drive
Vehicle expenses are usually the biggest deduction on an agent’s return and the one most often lost to bad records. The law requires contemporaneous records — written down as you go, not reconstructed from your calendar in April.
Use an app. MileIQ, Everlance, the mileage feature in QuickBooks — they run in the background, detect drives, and let you swipe business or personal. Thirty seconds a day.
For 2026 there’s an extra reason to get this right: the rate changed mid-year, 72.5 cents through June 30 and 76 cents after. A single annual mileage figure can’t be split between the two, so a careless log costs you the higher rate. The vehicle article covers the rest.
Step three: receipts, and what the $75 rule actually says
Here’s a rule that gets misquoted constantly.
Under the regulations, you don’t need a receipt for an individual business expense under $75. Lodging is the exception — a hotel always needs a receipt, no matter how cheap.
What people hear is “I don’t have to document anything under $75.” That’s not it. You still have to substantiate the amount, date, place, and business purpose of every expense. The $75 rule only relieves you of keeping the paper slip; a card statement plus a note covers it.
For meals and travel, that note matters more than the receipt: who was there, their relationship to you, and what business you discussed. A statement line reading “Ruth’s Chris $180” proves you spent money at a steakhouse. It doesn’t prove it was deductible.
Digital copies are fully acceptable under Revenue Procedure 97-22, so photograph the receipt and throw the paper away. Thermal receipts fade to blank within a year or two anyway — the shoebox is often full of nothing by the time anyone asks.
Step four: categories that match your tax return
Don’t invent a chart of accounts. Use the categories your deductions actually fall into, so that at year-end the numbers map straight onto the return: commission income, brokerage and desk fees, marketing, advertising, MLS and dues, education, software, phone, insurance, meals, contractors, office, professional fees.
Two that deserve their own line because they get handled differently: vehicle (which comes from your mileage log, not your bank statement, if you use the standard rate) and meals (which are only 50% deductible, so mixing them into general expenses overstates your deduction).
The deductions checklist covers what belongs where.
Step five: thirty minutes a month
Pick a day. The first Monday, the last Friday, whatever you’ll actually keep.
- Open the business account and categorize the month’s transactions
- Confirm the mileage app captured the month and fix anything mislabeled
- Note the business purpose on any meal or travel expense while you still remember it
- Move your tax set-aside to savings if you haven’t already
- Glance at the total: what came in, what went out
That’s it. Thirty minutes, twelve times a year, and you never face a reconstruction project.
The reason to do it monthly rather than quarterly isn’t accounting purity. It’s memory. You can reconstruct a coffee meeting from three weeks ago. You cannot reconstruct one from last March.
Step six: the quarterly look
Four times a year, spend a little longer:
- Check your year-to-date profit against last year
- Size and make your estimated tax payment
- Confirm your set-aside percentage still looks right for where the year is heading
And once a year, ideally in the fall rather than in April, look at the structural questions: whether your income has reached the point where a PA taxed as an S-corp makes sense, whether your salary is set correctly, and where you’re landing relative to the QBI thresholds. Those decisions have to be made during the year to matter for that year.
What software you actually need
Less than you think.
If you’re doing under roughly fifty transactions a month, a well-built spreadsheet plus a mileage app is genuinely sufficient. I’d rather see a simple system you maintain than a sophisticated one you abandon in February.
Above that, entry-level accounting software that connects to your bank account earns its cost, mostly by pulling in transactions so you’re categorizing rather than typing. Whatever your tax preparer can work with is the right choice — ask before you subscribe.
If you have a PA on payroll, this stops being optional. You need real books, real payroll records, and documentation for accountable-plan reimbursements. That’s the point where a bookkeeper usually pays for itself.
How long to keep it
Three years from filing is the general rule. Six years if you omitted more than 25% of your income. No limit at all for fraud or an unfiled return.
Records for anything you depreciate — vehicles, computers, equipment — need to survive as long as you own the asset plus the normal period after you dispose of it. Since digital storage costs nothing, seven years for everything is the simplest policy.
The mistakes I see every tax season
- One account for everything. Every problem downstream traces back to this.
- The April reconstruction. Ten months of memory, a stack of faded receipts, and a number that’s a guess.
- Recording net commission when the 1099 reports gross. The splits and fees are deductions, not invisible. Report the gross and deduct them.
- A mileage total with no dates behind it. Especially costly in 2026.
- Receipts with no business purpose noted. The amount was never the hard part to prove.
- Buying software and never opening it. A spreadsheet you maintain beats a subscription you don’t.
The bottom line
Separate account, mileage app, receipts photographed, thirty minutes a month. That system costs you six hours a year and makes every other decision in this series possible — because you can’t plan around numbers you don’t have.
I keep a Real Estate Agent Deduction Checklist and matching tracking spreadsheets for exactly this. They’re available on request; email me at don@fallenbaumcpa.com and I’ll send them over.
If you’d rather hand the whole thing off, that’s what our accounting and bookkeeping services are for — books kept current through the year, so the tax return is a summary rather than an excavation.
If your books are already a mess and you’d rather not face it alone, schedule a free consultation. Cleaning up a bad year is routine work — I’ve never once been shocked by anyone’s shoebox.
