The Real Cost of Not Tracking Your Mileage (You're Leaving $8,700+ on the Table)
Let me do some quick math on your driving.
You do 15 inspections a month. Average 40 miles round trip per inspection. That's 600 miles a month for inspections alone. Add comp drive-bys (for now - UAD 3.6 is eliminating those), courthouse trips, and other business driving, and you're looking at 800-1,500 miles per month.
At the 2026 IRS standard mileage rate of $0.725 per mile, that's a deduction of $6,960-$13,050 per year. Not a small number.
And most appraisers I work with are either not tracking their mileage at all, tracking it inconsistently, or estimating at tax time - which means they're either claiming less than they should or claiming without the records the IRS requires.
Either way, they're leaving money on the table.
The Number That Should Make You Angry
If you drive 12,000 business miles per year (conservative for most full-time appraisers) and you're not claiming the mileage deduction, you could be paying significantly more in taxes than you need to. At a 25-30% effective tax rate (your rate may differ), $8,700 in unclaimed deductions means roughly $2,100-$2,600 left on the table.
If you drive 18,000 miles (common for rural appraisers or those covering large service areas), you're potentially leaving $3,250-$3,900 per year in unnecessary taxes.
Over a 10-year career stretch, that's $21,000-$39,000 that went to the IRS instead of staying in your pocket. Because you didn't track your mileage.
One appraiser I worked with started tracking properly and discovered he was driving 16,400 business miles per year - significantly more than his "about 12,000" estimate. The difference was $3,190 in additional deductions he'd been missing. Every year.
Why Appraisers Are Particularly Bad at This
It's not laziness. It's the nature of the work.
You start your day at the first inspection. You drive to a second. You swing by the courthouse. You drive to a comp. You stop for gas. You head home. Somewhere in there, you were supposed to note the starting odometer, the ending odometer, and the business purpose of each trip.
Nobody does this consistently with pen and paper. The appraisers who tried have a glove compartment full of half-filled mileage logs from January that stopped being updated by March.
The problem isn't motivation. It's that manual mileage tracking is incompatible with how appraisers work. You're in your truck. Your hands are on the wheel. You're thinking about the inspection, not a mileage log. By the time you get home, you can't remember whether you drove 38 miles or 45 miles to that rural property.
What the IRS Actually Requires
The IRS requires "contemporaneous records" for mileage deductions. That means records made at or near the time of the trip - not reconstructed from memory at tax time. Specifically, you need:
The date of each trip. The business purpose (inspection at [address], comp photo at [address], courthouse records). The starting and ending mileage, or the total miles for the trip.
"I drive about 1,000 miles a month for work" is not an adequate record. The IRS wants trip-level documentation.
If you're audited and can't produce these records, you lose the deduction entirely. Not partially - entirely. That's the risk of estimating.
The Fix (It Takes 30 Seconds Per Day)
The appraisers who track mileage successfully all use the same approach: automatic logging tied to their daily workflow.
The simplest version: an app on your phone that logs GPS-tracked trips automatically. You start driving, it starts recording. You stop, it stops. At the end of the day, you tag each trip as business or personal. Thirty seconds.
The better version: mileage tracking built into the system you're already using for orders. When you have today's inspections in your route planner, the mileage logs itself as you drive to each property. No separate app. No manual entry. The business purpose is already recorded because it's attached to the order.
This is how we built mileage tracking into Appraiser Machine - your inspections feed into the route optimizer, which plans the most efficient route with live traffic, and every mile is logged automatically at the current IRS rate. At the end of the year, you export a complete, IRS-compliant mileage report. No manual tracking. No glove compartment logs. No reconstructing at tax time.
Mileage vs. Actual Expenses: Which Should You Use?
The IRS gives you two options for deducting vehicle expenses: the standard mileage rate ($0.725/mile in 2026) or actual expenses (gas, maintenance, insurance, depreciation, etc.).
For most appraisers, the standard mileage rate is simpler and often produces a larger deduction. It's one number multiplied by your total business miles. No receipts to track for gas. No pro-rating insurance premiums. No depreciation calculations.
The actual expense method can produce a larger deduction if you drive a newer, expensive vehicle with high gas and maintenance costs. But it requires tracking every vehicle expense and calculating the business-use percentage.
Talk to your CPA about which method makes sense for your situation. Either way, the foundation is the same: you need accurate mileage records.
Start This Week
If you're not tracking mileage right now, start this week. Don't wait for January. Don't wait for a new app. Don't wait for the perfect system.
Open the notes app on your phone. For each inspection this week, note the date, the address, and the round-trip miles. At the end of the week, add them up. Do the math at $0.725/mile. Look at the number.
That number - every week, every month, every year - is money you're either claiming or giving away.
The appraisers who track every mile keep $2,000-$4,000 more per year than the ones who don't. For the same driving. The same gas. The same wear on their truck. The only difference is a 30-second daily habit.
