Landlord Mileage Log for Taxes

TL;DR: The IRS requires a contemporaneous log of business miles — date, purpose, start/end mileage. Miss the log and the deduction is disallowed on audit.

_Last reviewed: July 2026 · 4 min read_

If you drive to your rental property and want to deduct the miles, the honest answer is: the deduction is real, but the IRS requires a contemporaneous log — date, purpose, start/end odometer readings. A log you reconstruct in April from memory (or a phone's location history) gets thrown out on audit. The tax savings are worth the 30-second habit; the audit risk of no log isn't.

Okoniq Property Hub stores mileage entries per property so a defensible year-end total is a report, not archaeology.

What is the standard mileage rate?

The IRS sets an annual standard mileage rate that covers vehicle depreciation, gas, maintenance, insurance, and typical operating costs. For 2026, the business mileage rate is roughly 70¢ per mile (check the current rate at IRS.gov — it changes yearly).

A landlord who drives 1,200 miles per year for rental purposes deducts about $840. Over 5 years of active management, that's $4,200 — real money.

Alternative: actual expense method — track gas, insurance, depreciation, maintenance separately and deduct the business-use percentage. More paperwork; usually only wins on gas-guzzling vehicles or heavy commercial use.

What trips qualify?

Deductible rental-related mileage:

• Driving to the rental for inspection, repairs, or showings
• Trips to hardware stores for rental repairs (with proof — receipt matched to the trip date)
• Meetings with tenants, property managers, contractors
• Trips to the bank to deposit rent checks
• Trips to the courthouse for eviction filings
• Trips to your CPA or attorney for rental matters

NOT deductible:

• Commuting to your day job
• Personal errands even if you pass by the rental
• Trips to look at potential future rentals you don't yet own (that's investor activity, not business)

What does the IRS require in the log?

Four data points per trip:

1. Date
2. Business purpose (specific — "inspection at 123 Main St," not "rental stuff")
3. Start and end odometer readings (or total miles, more common)
4. Vehicle (if you use multiple vehicles)

You don't have to track your total annual miles for the standard mileage method — just business miles. If you're using actual expense method, you also need total annual miles to calculate the business-use percentage.

Full IRS requirements are in Publication 463 (Travel, Gift, and Car Expenses).

Why "reconstructed" logs fail

Audit case law is settled: a mileage log created after the fact (e.g., "let me look at my calendar and my Google Maps timeline") is treated as unreliable and the deduction is disallowed. Even if the miles were legitimate, the lack of contemporaneous documentation is the killer.

"Contemporaneous" means recorded near the time of the trip. Weekly log entries are usually accepted; monthly entries are borderline; April reconstruction fails.

What are the tracking options?

Three that work:

1. Paper notebook in the glove box. Old school but perfectly acceptable. Update after each trip.
2. Phone app — MileIQ, Everlance, Stride, Hurdlr. GPS-based; auto-detects trips; you classify business/personal. Fee ~$5-10/month.
3. Okoniq's built-in mileage log — attach trips to specific properties so the deduction is already categorized.

The habit matters more than the tool.

What about my primary personal vehicle?

Fine to use. If you use one vehicle for both personal and business trips, only the business trips are deductible. Standard mileage method makes this clean — no percentage allocation needed for the deduction, you just count business miles.

If using actual expense method: business-use percentage = business miles ÷ total miles. Apply that % to gas, insurance, depreciation, etc.

One switching-methods gotcha

If you take the standard mileage rate the first year you use a vehicle for the rental, you can switch between methods later. If you take actual expenses first year, you're locked into actual expenses for that vehicle's life. Standard first, then switch — this is why most landlords stay on standard.

Keep miles logged with the property

Rental mileage tracking is high-value, low-effort — as long as the habit is consistent. Okoniq Property Hub stores mileage per property and per trip so the year-end Schedule E line is calculated correctly.

Frequently asked questions

Can I deduct mileage to look at potential future rentals?

Not as a rental expense — that's investor activity and generally not deductible as a business expense until you actually acquire the property. Miles specific to a property you subsequently buy may be capitalized into basis.

What about tolls and parking?

Deductible separately from the standard mileage rate. Save receipts.

Can I deduct depreciation on my vehicle AND take standard mileage?

No — standard mileage rate already includes depreciation. Actual expense method requires tracking depreciation separately.

FAQ

How many years back can the IRS audit my mileage deduction?

Typically three years from the date you filed, but if the IRS suspects substantial understatement of income (25% or more), the window extends to six years. Keep your mileage logs for at least three years after filing, longer if you're conservative.

What happens if I forget to log a few trips during the year?

You lose those specific deductions — the IRS won't accept estimated or averaged miles for gaps in your log. If you remember a trip but didn't log it contemporaneously, you can't reconstruct it later and claim it. This is why weekly habit beats monthly catch-up.

Do I need receipts for gas if I use the standard mileage rate?

No — the standard mileage rate already covers gas, so the IRS doesn't require fuel receipts. You only need the mileage log itself. If you switch to actual expense method in a future year, then you'd track and keep gas receipts.

Can my spouse drive to our rental and I claim the miles on my return?

Yes, as long as the trip is for your rental business and you file jointly. The vehicle owner and driver don't have to be the same person claiming the deduction — the rental activity is what matters. Log the trip the same way.
