Mileage is the single biggest tax deduction most mobile notaries qualify for, and it's also the one most notaries botch by not logging it correctly. Here's how the deduction actually works in 2026, and how to make sure you don't lose it.
Quick Answer
2026 IRS rate: 72.5¢/mile (Jan–Jun), 76¢/mile (Jul–Dec)
Typical notary deduction: $2,500–$8,000+ per year depending on volume
What the IRS requires: A contemporaneous log — date, start/end location, purpose, and miles for every trip
Best way to actually capture it: An automatic mileage tracking app, not a notebook
This page works best alongside the Smart Money Management guide (bank accounts, credit cards, and the rest of the tax deduction list) and the pricing guide, since your real hourly rate depends on what driving is actually costing and saving you.

This only works if the miles are logged
The IRS requires a contemporaneous log (date, locations, purpose, miles) for every trip. An app that tracks automatically is the only realistic way to actually capture this deduction.

Unlike an office-based business, your car is core equipment. A mobile notary driving 5,000–10,000 business miles a year is sitting on a $3,600–$7,600 deduction at the current 2026 rate — money that directly reduces what you owe the IRS, not just a nice-to-have write-off.
What Counts as Business Mileage
If your home is your principal place of business (true for most mobile notaries — no separate office you commute to), trips from home count as business miles, not commuting. That includes:
- Driving to and from signings and notarization appointments
- Supply runs (paper, toner, journal, stamp supplies)
- Bank trips to deposit checks or handle business banking
- Notary association meetings, continuing education, and networking events
- Trips to FedEx/UPS or a print shop for business purposes
What does not count: your regular commute if you also work a separate job with a fixed location, and any personal errands you run along the way.
2026 IRS Standard Mileage Rate
The IRS made a rare mid-year adjustment in 2026. Make sure you're using the right rate for the right half of the year when you calculate your deduction.
| Period | Business Rate | Notes |
|---|---|---|
| January 1 – June 30, 2026 | 72.5¢/mile | Up 2.5¢ from the 2025 rate |
| July 1 – December 31, 2026 | 76¢/mile | Mid-year increase, up 3.5¢ |
Rates set by the IRS. If you're filing for a different year, verify the current rate at irs.gov before you file — it changes annually and, as 2026 showed, can change mid-year too.
Standard Mileage Rate vs. Actual Expenses
You get to pick one method per vehicle (with some restrictions on switching later). Here's how they compare for a typical mobile notary.
| Factor | Standard Mileage Rate | Actual Expenses |
|---|---|---|
| What you track | Miles driven for business, per trip | Every gas, repair, insurance, and depreciation receipt |
| Effort | Low — one app running in the background | High — receipts plus a business-use percentage calculation |
| Best for | Most mobile notaries, especially with an economical vehicle | Expensive or high-maintenance vehicles with real deductible costs |
| Typical result | Usually equals or beats actual expenses for reliable daily drivers | Can win for gas-guzzlers or vehicles with big loan interest/repairs |
Most notaries use the standard mileage rate. It's simpler, and for a typical reliable daily-driver vehicle it usually matches or beats what actual expenses would produce.
IRS Record-Keeping Requirements
The IRS requires contemporaneous records — logged at the time of the trip, not reconstructed from memory months later. For every business drive, you need:
- Date of the trip
- Starting location
- Destination
- Business purpose (client name, type of appointment)
- Miles driven
Reality check: A notebook log works for about two weeks before it stops happening. If the IRS audits you and your mileage log was reconstructed after the fact, they can reject the deduction entirely — turning a $3,000–$8,000 write-off into $0.
Best Mileage Tracking Apps
An app that detects drives automatically solves the "I forgot to log it" problem. Here's how the main options compare.
MileIQ
Best for: Notaries who drive regularly and want it fully automatic
Price: $60/year or $6/month (40 free drives/month to start)
How It Works:
- Automatically detects when you drive — no manual start/stop
- Swipe right for business, left for personal, after each trip
- Learns your regular routes and can auto-classify repeat trips
- Exports IRS-compliant mileage reports
- Calculates your total deduction using the current IRS rate
Everlance
Best for: Notaries who want mileage and expense tracking combined
Price: $60/year or $8/month
Automatic mileage tracking plus receipt scanning and expense categorization in one app. A reasonable pick if you'd rather not run separate mileage and accounting tools.
Stride
Best for: Part-time notaries and tight budgets
Price: Free
Automatic tracking with a free tier that covers the basics — good for year one or lower mileage volume. Upgrade to a paid app once your mileage (and the deduction) grows.
Manual Log (Notebook or Spreadsheet)
Best for: Nobody, honestly — use an app
Free, but you'll forget. Reconstructed logs are exactly what the IRS rejects in an audit. If you're going to try it anyway, log every trip the same day, not at tax time.
Common Mileage Deduction Mistakes
❌ Reconstructing Mileage at Tax Time
Guessing your annual mileage from memory in April is not a contemporaneous record. If audited, the IRS can disallow the entire deduction.
❌ Deducting Both Standard Mileage and Gas Receipts
Pick one method. The standard mileage rate already bakes in gas, maintenance, and depreciation — you can't also deduct gas receipts on top of it.
❌ Using the Wrong Rate for the Wrong Half of 2026
Miles driven January through June 2026 are worth 72.5¢/mile. Miles driven July through December 2026 are worth 76¢/mile. Mixing them up under- or over-states your deduction.
❌ Not Tracking "Small" Trips
A 3-mile supply run feels too small to log. Do that 3 times a week for a year and it's real money left on the table. Automatic tracking catches these without extra effort.
Frequently Asked Questions
Can mobile notaries deduct mileage?
Yes. Driving to appointments is a legitimate business expense. If your home is your principal place of business, trips from home to a signing are deductible business miles, not commuting.
What is the 2026 IRS mileage rate?
72.5 cents per mile for January through June 2026, then 76 cents per mile for July through December 2026 after a mid-year IRS increase.
Do I need a mileage tracking app?
The IRS requires a contemporaneous log of every trip. Manually logging every drive is realistic for a week, then most people stop. An automatic tracking app is the only reliable way to actually capture the deduction over a full year.
Standard mileage vs actual expenses — which is better for notaries?
Most mobile notaries come out ahead with the standard mileage rate because it's simpler and doesn't require tracking every gas, repair, and insurance receipt. Actual expenses can win out if you drive an expensive or high-maintenance vehicle.
What if I use my car for a day job too?
Only the business-use portion counts. Track miles for notary work specifically — regular commuting to a separate job is never deductible, even on days you also do a signing.
