Real Estate Agent Mileage Deduction: How to Track, Calculate, and Defend It in 2026

Every mile you drive falls into one of two boxes. Business miles are deductible against commission income. Personal miles are not, and commuting sits inside the personal box no matter how far you drive or how early you leave. The real estate agent mileage deduction lives entirely on which box each trip belongs in, and the sorting rule is older than any app on your phone.

Once the working day starts, travel between business locations counts. Brokerage to a listing appointment counts. One showing to the next counts. A showing to the title company for a closing counts. So does the run to the county recorder, the drive to a home inspection you attend, the trip to pick up sign riders and lockboxes, the drive to a continuing education class and the drive to a board meeting. Trips to the bank to deposit a commission check count as well. Publication 463 is the governing guide, and every one of those miles ends up reducing profit on Schedule C.

Commuting is the drive between your home and a regular place of business. If your brokerage office is where you regularly work, the morning drive there is personal, and so is the evening drive back. Stopping for coffee on the way does not convert it. Putting a magnetic sign on the door does not convert it either, which surprises people. There are two openings worth knowing. If you have a regular work location away from home, travel from home to a temporary work location in the same business is deductible regardless of distance. And travel from home to a temporary site outside the metro area where you live and normally work is deductible as well.

Mixed trips need a rule of their own. A drive that stops at a showing and then continues to the grocery store splits at the point the business purpose ends. The miles to and from the showing are business. The detour is not, and attaching a business stop to an otherwise personal errand does not convert the whole loop. Previewing homes you might buy for yourself is personal even though you tour them with a lockbox code. Agents lose more accuracy to mixed trips than to any other category, because the log entry gets written once at the end of the day for the entire loop.

Put a number on an ordinary year. An agent logs 18,000 business miles out of 24,000 total miles driven. At the 72.5 cent standard rate, that is 13,050 dollars of deduction. Because commission income also carries self-employment tax computed on Schedule SE, an agent in the 24 percent bracket keeps roughly 4,950 dollars of combined tax on that single line. The same agent with sloppy tracking who claims only the 9,000 miles she happens to remember gives up about 2,470 dollars for no reason other than record habits.

The mistake we correct most often runs the other direction. An agent counts the daily drive from the house to the brokerage as business because the car has a brokerage decal and the phone rings the whole way. Without a qualifying home office, that drive is commuting, and adding it to the log taints the credibility of every other entry when someone reviews the file. Two hundred working days of a 22 mile round trip is 4,400 personal miles worth 3,190 dollars of deduction that does not belong on the return.

Sorting the trips correctly is a bookkeeping habit rather than a filing season project, and monthly bookkeeping keeps the mileage log tied to the same calendar the rest of the business runs on. These are federal rules, state treatment of the same expense varies, and our clients in Austin, Chicago, Los Angeles, Miami and New York City each see a different state result stacked on the federal one. Fix the sorting rule in your head this week and the deduction takes care of itself for the rest of your career.

Yes, and this is the single largest lever most agents have. If your residence is the principal place of business under section 280A, then travel between your home and any other work location in the same business is deductible. The first drive out and the last drive home stop being commuting. A qualifying home office changes the real estate agent mileage deduction more than any other fact on the return, and it changes it every working day of the year rather than once.

The office has to actually qualify. That means a space used exclusively and regularly for business, and it means you have no other fixed location where you conduct substantial administrative or management work. Most agents meet the second half because the listing input, the transaction coordination and the invoicing happen at a desk at home rather than at the brokerage. Publication 587 walks the tests, and the expense side of the office is reported on Form 8829 when you use actual costs.

One technical point clears up a lot of confusion. The mileage benefit follows from the home qualifying as the principal place of business, not from the method you pick to deduct the office. An agent who takes the simplified rate instead of filing Form 8829 still gets the first-trip treatment, because the underlying test is identical. Even an agent whose office deduction is fully suspended by the gross income limit in a thin year still qualifies, since the space met the test regardless of how much of the expense survived the ceiling.

Here is the arithmetic that gets overlooked. An agent works 230 days a year and averages 32 round trip miles between the house and the first stop plus the last stop of the day. That is 7,360 miles. Without a qualifying office those miles are commuting and worth nothing. With one, they are business miles worth 5,336 dollars at the 72.5 cent rate. At a combined federal and self-employment rate near 38 percent, the office is worth about 2,027 dollars of tax through the mileage channel alone, before the office itself deducts a single utility bill.

That figure often exceeds the home office deduction itself. An agent with a 180 square foot office in a modest house might claim 900 dollars under the simplified rate. The mileage effect is five times larger. Agents who dismiss the home office as too small to bother with are usually looking at the wrong half of the benefit, and we raise this in nearly every tax strategy consulting session with a newly independent agent.

Now the warning. You cannot have it both ways. An agent who keeps a private office at the brokerage where the real administrative work happens does not have a qualifying home office, and claiming the first drive of the day as business in that situation is a position that fails on review. The examiner asks a simple question, which is where the paperwork actually gets done, and the answer usually shows up in badge records or in the calendar. A home office claimed only to unlock mileage, with no dedicated space behind it, puts both deductions at risk rather than one.

The mistake we correct most often is the agent who sets up a real home office in July and then claims the mileage benefit for the whole year including January through June. The office has to exist for the period claimed. Split the year, log the change date and claim the first-trip miles only from the month the space went into service. Document the setup date with a photograph and a receipt for the desk.

One more point of order. This treatment applies to work locations in the same trade or business. A drive from the house to a rental property you personally own is a different activity reported on a different schedule, and mixing the two inside one mileage log muddies both. Keep the log clean by business, set the office up properly before January, and the first mile of every future day starts working for you.

The real estate agent mileage deduction can be computed two ways, and the choice you make in the first year of a vehicle can bind you for as long as you drive it. The standard rate of 72.5 cents per business mile stands in for gas, oil, maintenance, tires, insurance, registration and depreciation. The actual expense method adds those costs up for real and applies your business use percentage to the total, with depreciation claimed on Form 4562 under the rules in Publication 946.

Some costs sit outside the choice. Business parking and tolls are deductible under either method. For a self-employed agent, the business portion of car loan interest is deductible on top of the standard rate as well, and so is the business share of personal property tax on the vehicle in states that charge it. Parking tickets never are, no matter how urgent the showing was. Publication 463 lists what each method absorbs.

Work the comparison on a real car. An agent drives 24,000 miles, of which 18,000 are business, so business use is 75 percent. Standard method: 18,000 times 72.5 cents is 13,050 dollars. Actual method on a paid-off midsize sedan: 3,400 dollars of fuel, 2,200 dollars of insurance, 1,300 dollars of maintenance and tires, 400 dollars of registration, for 7,300 dollars of operating cost. Seventy-five percent of that is 5,475 dollars. Add 2,600 dollars of remaining depreciation and the actual method reaches 8,075 dollars. The standard rate wins by 4,975 dollars. Flip the facts to a newly purchased large vehicle and the answer often reverses, because the depreciation piece dominates in the early years.

The first-year election is where agents lock themselves in without knowing it. On a vehicle you own, you must choose the standard rate in the first year the car is available for business use if you ever want to use it for that car. Claim accelerated depreciation in year one instead and the standard rate is closed to that vehicle permanently. Start with the standard rate and you keep flexibility, because you may switch to actual expenses later, though depreciation from that point forward must run on the straight line method over the remaining recovery period.

Leases follow a stricter version of the same idea. If you choose the standard rate for a leased vehicle, you have to use it for the entire lease term, including any renewal. There is no switching to actual expenses in year two because the lease payment suddenly looks attractive. That single sentence decides thousands of dollars over a three year lease, and it is decided in the month you first drive the car for business.

Two limits catch a growing team. The standard rate is unavailable if you operate five or more vehicles at the same time in the business, which matters for an agent who builds a team and puts assistants on the road. It is also unavailable for a vehicle on which you previously claimed a section 179 deduction or bonus depreciation. Neither rule bothers a solo agent with one car, and both bite a team leader who scaled up without revisiting the tax plan.

The mistake we see most often is the agent who lets a software default make the election. The return gets prepared quickly in the first year with actual expenses because receipts were handy, and four years later, when the car is paid off and the standard rate would produce far more, the door is shut. Model both methods across the expected life of the vehicle before the first return is filed rather than after. Do that once at purchase and the choice stops being an accident.

Whichever method you pick, the mileage log still has to exist, because the business use percentage drives the actual method just as surely as it drives the standard one. Buy the car with the tax result already modeled and the next several years of returns get easier rather than harder.

A real estate agent mileage deduction survives review on the strength of its log and almost nothing else. Section 274(d) treats a passenger vehicle as listed property, which means the ordinary rule allowing a judge to estimate a reasonable expense does not apply. No adequate records means no deduction, even when everyone agrees the driving happened. That is a harsher standard than the one covering office supplies, and it catches people who assume a reasonable estimate is good enough.

Four items per trip do the job. The date, the destination, the business purpose and the miles driven. Add the odometer reading on January 1 and December 31 so total annual miles are provable, because business percentage is a fraction and a fraction needs a denominator. The IRS recordkeeping guidance sets the general expectation, and Publication 463 gives the specific vehicle standard along with sample log formats.

Contemporaneous means near the time of the trip, not perfect same-minute entry. A log completed weekly is treated far better than one assembled in March from memory. Apps that capture drives automatically through the phone solve the distance problem completely, but they do not solve the purpose problem. An automatic capture that says fourteen miles to an address proves distance, not business character. Classify each drive inside the app every week while you still remember whether that address was a listing appointment or your mother’s house.

A sample period can support a full year when the pattern holds. If your driving is consistent, a carefully kept three month log plus evidence that the rest of the year looked the same can support the annual figure. This works for an agent with a steady territory and a steady schedule. It works poorly for an agent whose volume tripled in the fall, and it does not work at all if the sample itself is thin.

Reconstruction after the fact is a fallback rather than a plan. Calendar entries, showing service history, lockbox access records, closing statements and client emails can rebuild a credible picture, and we have done it many times for clients who arrived with nothing. It costs real money in professional time and it produces a weaker file than a five second entry would have. Some of the year is usually lost because the supporting trail simply is not there.

Keep the log for as long as the return stays open. Three years from the filing date is the ordinary assessment window, and six years applies where income was substantially understated. A log stored only inside an app you later stop paying for is a log you no longer have, so export the full year to a file every January and store it beside the return. Back up the export, then confirm the file actually opens before the subscription lapses.

Here is what the failure costs. An agent claims 14,000 business miles for 10,150 dollars of deduction and cannot produce a log. The deduction is disallowed in full. At a combined federal and self-employment rate near 38 percent, that is about 3,857 dollars of additional tax, plus interest running from the original due date, plus a possible accuracy related penalty of 20 percent on the underpayment. Nothing about a well kept log removes every audit risk, but it turns a bad conversation into a short one.

The common mistake is logging distance without purpose. Agents produce a beautiful spreadsheet of dates and mileage totals with a blank purpose column, and the file collapses because the one item that proves business character was never captured. Two words per trip fixes it. Write listing appointment or buyer showing next to the address, review the log with your tax return preparer each January, and the record you build this year will still be defending you three years from now.

Almost never, and this is the position that draws the most attention on an agent return. The real estate agent mileage deduction claimed at 100 percent business use on a household’s only vehicle tells a reviewer that groceries, school pickup, the dentist and every weekend trip happened in some other car that does not exist. The claim is not merely aggressive, it is arithmetically implausible, and it invites a look at everything else on the return.

The forms ask about this directly. The listed property section of Form 4562 asks whether another vehicle is available for personal use and whether the evidence supporting the business use claim is written. Answering those questions honestly is the beginning of a defensible position. Answering them carelessly creates a contradiction between the form and the facts before anyone has looked at a single receipt.

Run the numbers on a correction. An agent drives 24,000 total miles and claims 22,000 as business, or 92 percent, producing 15,950 dollars at the standard rate. On review, personal errands averaging 40 miles a week and one 900 mile family trip bring real business use down to 70 percent, or 16,800 miles, producing 12,180 dollars. The 3,770 dollar difference costs roughly 1,430 dollars of tax at a combined 38 percent rate, before interest. The corrected figure was still a strong deduction. The overstatement bought nothing and cost credibility.

A second vehicle changes the picture honestly. An agent whose household keeps a personal truck for weekends and errands can support a high business percentage on the work car, because the personal miles have somewhere else to go. Note the second vehicle on the log, record its rough annual mileage and the high percentage stops looking strange. This is a documentation exercise rather than a tax trick.

Business use is recomputed every year and never copied forward. An agent who ran 78 percent one year and then spent the next year on partial leave at 41 percent has to report the second year at 41 percent, even though neither the car nor the job changed. Copying last year’s percentage is one of the quietest errors on an agent return, and it usually travels with the software rather than with the taxpayer. Read the actual odometer spread each January instead of accepting the number the prior file suggests.

Two related items get mishandled at the same time. Business parking at a closing or a client meeting is deductible, while parking at the brokerage where you regularly work is a commuting cost and is not. And a vehicle used by a spouse who is not in the business generates personal miles even when the car is titled to the agent. Both of those show up as small overstatements that accumulate across a return, and both are easy to get right once you know they exist.

The mistake underneath all of this is treating business use percentage as an opinion rather than a measurement. Agents pick 90 percent because it feels close, then defend it later with nothing behind it. Measure it instead. Total miles from the odometer, business miles from the log, and the percentage falls out of the division. A measured 74 percent is worth far more than an assumed 95 percent that collapses. Agents who want their vehicle position reviewed before filing can Request Private Consultation and bring last year’s return along with the current log.

Federal rules govern all of this, though state treatment of vehicle costs varies and depends on where you file. Set the odometer reading on the first working day of January, classify each drive weekly, and by December the percentage is a fact rather than a guess. Do that for one full year and every year after it becomes routine.
