Every article about the landlord mileage deduction leads with the rate. Almost none of them leads with the rule that decides whether the rate applies to you, so here it is up front: for most landlords, the drive from home to the rental is commuting, commuting is personal, and personal miles deduct at zero cents each. The IRS does not care that the destination is a building you own, insure, and report income from. A trip between your house and a regular work location is a commute, and a rental you visit on a routine basis is a regular work location.
That trap makes or breaks the deduction for a small portfolio, because for an owner with one or two properties in town, home-to-rental trips are most of the driving. The rest of this guide sorts the drives that count from the ones that do not, works the 2026 rate against realistic numbers, and lays out the four-column log that turns miles into a deduction an auditor will accept.
The commute trap, and the exception that defuses it
The governing document for car expenses is IRS Publication 463, and its commuting rule is blunt: transportation between your home and a regular place of work is a personal commuting expense, no matter the distance and no matter how much work you do when you arrive. For a self-managing landlord without a home office, the first leg of the day, house to rental, and the last leg, rental back to house, are personal. Only what happens in the middle can be business.
The exception is a qualifying home office. If the room where you run the leases, the books, and the scheduling is your principal place of business, there is no commute left to disqualify: every drive from that office to a rental, a supply house, the bank, or your CPA's office starts at your place of business and counts as business mileage. The office has its own two-gate test, covered in our guide to the home office deduction for landlords, and the two deductions travel as a package. The office is often worth a few hundred dollars by itself; the mileage it converts is frequently worth more.
Which drives count and which do not
With or without a home office, every trip lands in one of two buckets. These count:
- Drives between two of your rentals. Once you are at a work location, direct miles to the next one are business miles, office or no office.
- Drives from a rental to a business stop and back. The hardware store for a faucet cartridge, the bank that holds the rental account, a vendor's shop to pick up a part.
- Drives to meetings about the rentals. Your CPA, your attorney, your insurance agent, the county office that issues the rental license.
- Drives from home to any of the above, but only when a qualifying home office makes home your principal place of business.
And these do not:
- Home to rental and back, without the office. The bookend legs of the day are commuting even when the hours in between are real work.
- Personal errands woven into the route. Detour miles for groceries are personal, and one business stop does not convert a personal trip into a business one.
- Scouting properties you do not own yet. Miles spent house hunting are acquisition costs, not current Schedule E expenses; track them separately and ask your CPA how to treat them.
The reason for the trip decides the mile. The name on the deed does not.
The 2026 rate, worked
The math itself is one line:
Mileage deduction = business miles × $0.725 (the 2026 IRS standard mileage rate of 72.5 cents per mile)
The current rate is published on the IRS standard mileage rates page, and it is an all-inclusive figure: gas, oil, tires, repairs, insurance, registration, and the vehicle's depreciation are all baked into the 72.5 cents. You cannot deduct those costs again on top of it. Parking fees and tolls for business trips are the exception; they stack on top of the rate.
Say you self-manage a duplex 9 miles away and your home office qualifies. Two visits a month at 18 round-trip miles is 36 miles a month, 432 a year, $313.20 at the 2026 rate. Add 30 supply runs averaging 11 miles each, another 330 miles and $239.25, and one ordinary duplex has produced 762 miles and $552.45 of deduction. A three-property portfolio that logs 2,400 business miles in a year is looking at $1,740. None of this is fortune-making money, but it recurs every year, and the cost of claiming it is writing down a number at the end of each drive.
The alternative is the actual expense method: total every cost of running the car for the year, then deduct the rental-use percentage of it. Two things to know before you are tempted. You must choose the standard rate in the first year you use the car for the rentals if you want to keep the choice open later, and for a vehicle that is 5 or 10 percent rental use, tracking every fuel receipt and repair invoice rarely beats the flat rate. Most small landlords take the standard rate and keep driving.
The log the IRS will actually accept
Publication 463 asks for records kept at or near the time of the trip. That word, timely, is where mileage deductions die: a log reconstructed in March from a calendar and a guess is exactly what examiners are trained to disallow. The log does not need to be fancy. It needs four columns, filled in while the drive is still fresh:
- Date. One row per trip, the day you drove it.
- Destination. The property address or the vendor. This column also splits your miles by property at tax time, so be specific.
- Business purpose. What the trip accomplished. “Drain repair, unit 2” survives an audit; “maintenance” invites questions.
- Miles. Odometer start and end, or the standing round-trip figure for a route you drive every month.
Add two readings the columns do not capture: the odometer on January 1 and again on December 31. The vehicle questions on the return ask for total annual miles alongside business miles, and those two numbers are unrecoverable in April if nobody wrote them down. Where the log lives is up to you. A notebook in the glove box, a running note on your phone, a tab in your bookkeeping spreadsheet: the IRS accepts any of them, and the habit matters more than the format.
Where the number goes on the return
Rental mileage lands on Schedule E, line 6, “Auto and travel.” Schedule E reports each property in its own column, which is why the destination column in your log earns its keep: 432 of the miles belong to the duplex on Maple, 330 to the fourplex on Third, and the split takes a minute instead of an afternoon. Drop the log and the year's totals into the same folder as the rest of your year-end tax package, because your preparer needs the backup, not only the number.
Fold it into the monthly books
The log fails when it is a special project and survives when it is a line in a routine. I close my own books on the 5th of each month, and the mileage total goes in with everything else: sum the month's miles, multiply by the rate, enter the dollar figure as an expense like any other. Ten minutes, twelve times a year, and the deduction is done before tax season starts. The mechanics are the same monthly close habit that keeps the rest of your rental property accounting honest, applied to one more small recurring number.
Small recurring numbers are the ones spreadsheets lose, and that is why I built rents.ai. It will not count your miles for you: there is no GPS, no app riding along in the truck, and the log stays wherever you keep it. What it does is hold the result. Enter the month's mileage dollars as an expense against the right property, attach the log file to the transaction so the backup lives with the number, and the figure rolls into the per-property, Schedule E categorized year it builds for your CPA. The drive is your job. Remembering it happened is the part worth delegating.
The figures on this page are estimates to organize your year for your CPA, not tax advice. The commuting rules in particular turn on facts, like whether your home office qualifies and why a given trip happened, that only a preparer who can see your whole return should weigh. Keep the log, bring the totals, and let them make the calls.
