If you're a mobile notary or signing agent, there's a federal tax rule that most of your competitors don't know about — and it's costing them thousands every year. The IRS explicitly exempts fees from notarial acts from self-employment tax. That's a 15.3% break the IRS hands you for free, but only if you track your income correctly.
This guide walks through how the exemption works, how to allocate your income between notarial acts and signing agent services, and every deduction you should be claiming on Schedule C in 2026.
The Rule That Saves Notaries Thousands: IRC §1402(c)(2)
Internal Revenue Code Section 1402(c)(2) carves out a specific exclusion: fees you receive for performing notarial acts are not subject to self-employment tax. The Schedule SE instructions confirm it directly — notaries write "Exempt-Notary" on the appropriate line, and that income skips the 15.3% SE tax bill entirely.
Income tax still applies. But the self-employment tax portion — which is the biggest single tax most self-employed people pay — gets removed from any income that qualifies as a notarial-act fee.
What counts as a notarial act: The per-act fee your state authorizes you to charge for acknowledgments, jurats, oaths, affirmations, and certified copies. These are the small fees (typically $5–$15 per signature, capped by state law) that you'd charge for each notarization.
Notary Fees vs Signing Agent Fees: How to Allocate
Here's where most mobile notaries get tripped up. When a title company pays you $150 for a loan signing, that $150 is not all exempt. The fee is a bundle:
- Notarial-act portion (exempt from SE tax): The per-act fees for the signatures you actually notarize. If a typical refi has 5 signatures and your state allows $10 per act, that's $50 of the $150.
- Signing agent portion (subject to SE tax): The rest — travel, document handling, printing, scanning, return shipping coordination. This is service income, not notarial-act income.
Using that breakdown, only $50 of the $150 would be SE-tax-exempt. The remaining $100 is taxed like any other self-employment income.
⚠️ Recordkeeping is critical. The IRS won't accept "I think it was about half" at audit. You need a log that documents which fees came from notarial acts (and how many) versus signing-agent services. Without records, the IRS will treat all of it as SE-taxable.
Mileage: The Other Massive Deduction for Mobile Notaries
Mobile notaries drive. A lot. Many full-time signing agents log 25,000–40,000+ business miles a year traveling to title companies, signers' homes, hospital signings, and FedEx drop-offs. In 2026 the IRS standard mileage rate is 72.5¢ per mile for miles driven January–June and 76¢ for July–December after a rare mid-year increase — so 30,000 miles is worth roughly $22,000 off your taxable Schedule C income. We break down exactly which notary trips qualify and how to log them in our mobile notary mileage deduction guide.
| Annual Business Miles | Deduction at 72.5¢/mi (Jan–Jun) | Tax Savings (22% bracket + SE tax) |
|---|---|---|
| 15,000 | $10,875 | ~$3,950 |
| 25,000 | $18,125 | ~$6,580 |
| 35,000 | $25,375 | ~$9,210 |
| 50,000 | $36,250 | ~$13,160 |
Figures use the 72.5¢ first-half rate. Miles driven July 1 or later are worth 76¢ each, so your actual 2026 deduction is higher if you drive in the back half of the year — see the mid-year increase to 76¢.
Tax savings assume the miles offset signing-agent income (subject to both income tax and SE tax). The two methods for vehicle deductions — standard mileage vs. actual expenses — are compared in detail in our Standard Mileage vs Actual Expenses guide. For most mobile notaries with newer or moderately-priced vehicles, standard mileage wins.
⚠️ The IRS mileage log requirement. Per Pub 463, a contemporaneous log must record the date, business purpose, starting/ending odometer (or total miles), and destination of every business trip. Reconstructed logs at tax time get rejected at audit. Track in real time. (Full rules: IRS mileage log requirements.)

Beyond mileage, mobile notaries have a long list of legitimate Schedule C business deductions. Track them all year, not just at tax time:
| Category | Examples | Typical Annual Cost |
|---|---|---|
| Notary supplies | Seal/stamp, embosser, journal, certificates, blank notarial paper | $100–$300 |
| E&O insurance | Errors & Omissions policy (often $25K–$100K coverage) | $50–$300 |
| Notary bond | State-required surety bond (multi-year renewal) | $50–$200 |
| Commission & training | Commission renewal, NNA membership, signing agent certification | $100–$500 |
| Printing & supplies | Dual-tray printer, toner, paper, document scanner | $300–$1,500 |
| Phone & data | Business-use portion of cell plan, data overage on signing days | $300–$1,200 |
| Background checks | Annual NNA-required background screening | $25–$75 |
| Home office | Dedicated workspace for scheduling, document prep, scanning | Varies |
| Shipping & postage | FedEx/UPS to title companies, secure document return | $200–$800 |
| Software & tools | Scheduling apps, e-signing platforms, secure file transfer | $100–$600 |
A typical full-time mobile notary stacks $2,500–$5,000 in non-mileage deductions per year on top of vehicle expenses. (For more deduction strategies that apply, see our deductions guide — many overlap with signing agent work.)
Quarterly Estimated Taxes — Don't Get Hit With Penalties
If you expect to owe $1,000 or more in federal tax this year, you're required to make quarterly estimated payments. Missing them triggers an underpayment penalty even if you pay in full at filing. Full breakdown in our quarterly estimated taxes guide.
| Quarter | Period Covered | Due Date |
|---|---|---|
| Q1 2026 | Jan 1 – Mar 31 | April 15, 2026 |
| Q2 2026 | Apr 1 – May 31 | June 15, 2026 |
| Q3 2026 | Jun 1 – Aug 31 | September 15, 2026 |
| Q4 2026 | Sep 1 – Dec 31 | January 15, 2027 |
Putting It All Together: A Real Example
Let's say you're a full-time signing agent with $48,000 gross revenue from 320 loan signings. You drove 28,000 business miles. Here's how the math shakes out:
| Item | Amount |
|---|---|
| Gross signing revenue (320 signings × $150) | $48,000 |
| Allocated to notarial acts (~$50 of each) | $16,000 |
| Allocated to signing agent services | $32,000 |
| Mileage deduction (28,000 mi × 72.5¢, first-half rate) | −$20,300 |
| Other business expenses (supplies, E&O, printer, phone) | −$3,800 |
| Net Schedule C profit | $23,900 |
| SE-taxable portion (signing agent income − allocated expenses) | ~$13,750 |
| SE-exempt portion (notarial acts, "Exempt-Notary") | $10,150 |
| SE tax saved vs. taxing the full $23,900 | ~$1,433 |
That's roughly $1,400 of SE tax avoided by allocating income correctly — money the notary down the street is paying because they treat every dollar the same. Add the mileage and supplies deductions, and the total tax savings vs. a no-tracking notary easily reaches $7,000–$9,000.
The Recordkeeping Setup That Makes This Work
The Section 1402(c)(2) exemption only works if you have records that distinguish notarial-act fees from signing agent fees. Recommended practice:
- Keep your notary journal current — every signature you notarize, with the per-act fee tracked
- Log the per-signing breakdown: notarial-act fees vs the rest of the invoice
- Track every business mile contemporaneously with date, destination, and purpose
- Save every receipt for supplies, E&O, printing, postage — paper or app
- Run a monthly P&L so you know your quarterly tax estimate, not just at year-end
