Mobile notaries drive for a living, and every mile driven for a signing is deductible business mileage on Schedule C Line 9. The miles people miss are not the drive to the signing — those get logged — but the trip to overnight the package, the run to the county recorder, and the leg between two appointments. 2026 is a split-rate year, so a notary's log needs dates: 72.5 cents a mile through June, 76 cents from July 1.
Here's a number most mobile notaries never calculate: if you complete four signings a day and drive an average of 15 miles to each one, that's roughly 15,000 business miles a year. At the 2026 rate, that mileage alone is worth more than $11,000 in tax deductions. And almost none of it gets claimed properly, because most notaries never log the drive — only the signing.
This guide is about the miles, not the fees. If you want the self-employment tax angle — the notarial-act exemption that skips the 15.3% SE tax — that's covered in our mobile notary tax deductions guide. Here, we're focused on the single biggest deduction in your business: the driving.
Quick answer: Mobile notaries can deduct every business mile driven to and between signings using the IRS standard mileage rate. For 2026, that rate is 72.5¢ per mile for miles driven January–June and 76¢ per mile for July–December, after the IRS raised it mid-year. To claim it, you need a mileage log showing the date, distance, destination, and purpose of every trip.
Which Notary Miles Count as Business Miles
Yes — and it's usually the largest deduction a mobile notary has. Because your business model is driving to the signer, nearly every mile you put on your vehicle for work is deductible. The IRS lets you claim those miles one of two ways: the standard mileage rate or actual vehicle expenses. For the overwhelming majority of mobile notaries, the standard mileage rate wins — it's simpler, requires no receipts for gas or repairs, and at 76¢ a mile it's generous.
The catch is documentation. The IRS doesn't take "I drive a lot" as proof. You need a contemporaneous log — meaning recorded at or near the time of the trip — with four things for every drive: the date, the miles, where you went, and why. Miss those and the deduction can be disallowed in an audit, no matter how many miles you actually drove.
What mileage can a notary write off?
More than most notaries realize. The deductible trips include:
- Home base or office to a signing — if your home office qualifies as your principal place of business (common for mobile notaries, but it has to meet the IRS's exclusive-use test), the drive to the signer's location is deductible business mileage, not commuting.
- Between signings — every mile from one appointment to the next.
- Signing to the drop-off — trips to FedEx, UPS, the post office, or a title company to return completed documents.
- Supply runs — driving to buy stamps, journals, ink, or a new embosser.
- Business errands — the bank to deposit fees, the print shop, continuing-education or NNA events.
What's not deductible: personal stops woven into a business trip, and true commuting if you happen to have a fixed office you drive to daily. The dividing line is business purpose, which is exactly why the log has to capture purpose, not just distance.
How much is a notary mile worth in 2026?
This is where 2026 gets unusual. The IRS almost always sets one mileage rate for the whole year. This year it set two. In Announcement 2026-11, the IRS raised the business rate mid-year because of rising fuel prices — the first mid-year change since 2022. So 2026 is a split year:
| When you drove | Business rate | Value of 1,000 miles |
|---|---|---|
| Jan 1 – Jun 30, 2026 | 72.5¢/mile | $725 |
| Jul 1 – Dec 31, 2026 | 76¢/mile | $760 |
← Scroll to see the full table →
The rule to remember: use the rate that matches the date you drove, not the date you file. A signing you drove to on June 28 is deducted at 72.5¢; the same drive on July 2 is worth 76¢. That means your 2026 mileage log has to be date-accurate — a lump-sum "I drove about 14,000 miles this year" won't let you apply the split correctly. For the full breakdown of the change, see our 2026 IRS mileage rate guide.
Notary mileage deduction vs the SE-tax exemption: you get both
This trips up a lot of notaries, so it's worth being clear. There are two separate tax benefits, and claiming one does not affect the other:
- The mileage deduction lowers your taxable income on Schedule C. It applies to all your business driving, whether the income came from notarial acts or signing-agent work.
- The SE-tax exemption under IRC §1402(c)(2) removes the 15.3% self-employment tax from your notarial-act fees specifically. It has nothing to do with driving.
You claim both. Your miles reduce income tax across the board; your notarial-act fees skip SE tax. Handled together, the combination is what makes the mobile-notary tax picture genuinely favorable — if your records are clean enough to support it. The full deductions guide walks through the fee side in detail.
How do notaries prove mileage to the IRS?
With a log that meets the IRS's four requirements for every trip: date, distance, destination, and business purpose. See our complete guide to IRS mileage log requirements for exactly what an audit-proof log looks like.
The problem is that manual logging fails in the real world. Between signings, nobody reliably writes down odometer readings — you're managing documents, signers, and a schedule. By April, the log has gaps, and gaps are what get deductions denied. This is the practical reason a GPS-based tracker matters for notaries specifically: your day is a string of short, discrete drives to different addresses, which is exactly the pattern manual logs lose track of.
🚗 TrakMiles Pro logs every notary trip automatically
TrakMiles Pro is a state-of-the-art GPS mileage tracker with a complete double-entry accounting system built on top — designed for self-employed professionals who run a business out of their vehicle. It captures each signing trip with the date, distance, and route, applies the correct 2026 rate to each drive, and files it into real Schedule C–ready records. No manual odometer readings, no April scramble.
Because your day is many short trips, it also separates each one automatically instead of blending them into a single blob. And because it's a real accounting system, your mileage, fees, and expenses all live in one place — not scattered across a spreadsheet and a notebook.

Say you're a full-time signing agent. In the first half of 2026 you drove 7,000 business miles; in the second half, another 8,000. Here's the math with the split rate:
| Period | Miles | Rate | Deduction |
|---|---|---|---|
| Jan–Jun | 7,000 | 72.5¢ | $5,075 |
| Jul–Dec | 8,000 | 76¢ | $6,080 |
| Total | 15,000 | — | $11,155 |
← Scroll to see the full table →
That $11,155 comes off your business income before tax. If you'd logged the whole year at the old 72.5¢ rate, you'd have claimed $10,875 — the split-year increase alone added $280 for the same driving. And if you hadn't logged consistently at all, you'd be reconstructing it from memory in April and almost certainly leaving money on the table.

The setup that makes this work
The notaries who actually capture this deduction share one habit: they track in real time, not at tax time. Whatever tool you use, the system needs to record each trip as it happens, tag its business purpose, and apply the right 2026 rate by date. Do that, and the mileage deduction stops being an April guess and becomes a number you can defend.
Pair it with the notarial-act SE-tax exemption and clean quarterly estimated payments, and you've got the three pillars of a mobile-notary tax setup that keeps more of what you earn — legally, and without the year-end panic.
Frequently asked questions
Can mobile notaries deduct mileage?
Yes. Mobile notaries and signing agents can deduct business miles driven to and from signings using the IRS standard mileage rate. For 2026 that rate is 72.5 cents per mile for miles driven January through June and 76 cents per mile for July through December. The miles must be logged with the date, distance, destination, and business purpose.
What mileage can a mobile notary write off?
A mobile notary can write off miles driven from their office or home base to a signing, between signings, to the bank or post office to drop documents, and to buy notary supplies. Commuting to a fixed workplace is not deductible, but travel between business stops generally is.
Is the notary mileage deduction separate from the self-employment tax exemption?
Yes. The mileage deduction lowers your taxable income on Schedule C and applies to all your business driving. The self-employment tax exemption under IRC 1402(c)(2) is a separate benefit that applies only to notarial-act fees. Mobile notaries can claim both.
How do notaries prove their mileage to the IRS?
The IRS requires a contemporaneous mileage log showing the date of each trip, the miles driven, the destination, and the business purpose. A GPS-based app that records each signing trip automatically satisfies this requirement without manual logging.
