The Self-Employment Tax Reality
Most notary signing agents operate as sole proprietors — meaning you are self-employed, you file a Schedule C with your Form 1040, and you pay both the employee and employer share of Social Security and Medicare taxes. The combined self-employment tax rate is 15.3% on net self-employment income (12.4% Social Security + 2.9% Medicare), on top of regular income tax.
The good news: every legitimate business expense you deduct reduces your net self-employment income, which reduces both your income tax and your self-employment tax. A $1,000 deduction doesn't just save you income tax — it saves you income tax plus 15.3% SE tax on that $1,000. For a signing agent in the 22% federal bracket, a $1,000 deduction is worth roughly $370 in total tax savings.
The Notary Fee vs. Signing Agent Fee Distinction
This is the most misunderstood tax issue in the signing agent world. The IRS treats these two income types differently:
- Notary fees (the per-act fee for performing an acknowledgment or jurat) are exempt from self-employment tax but still subject to income tax
- Signing agent fees (fees for travel, document handling, and the appointment itself) are subject to both income tax and self-employment tax
In practice, most signing services pay a single blended fee. Separating the two requires documentation of how much of each payment is attributable to notarial acts vs. signing agent services. Most signing agents don't bother with this separation and simply pay SE tax on all income — which is conservative but leaves potential savings on the table. A CPA can help you structure this correctly.

Mileage: Your Biggest Deduction — Track It Right
For most active signing agents, mileage is the single largest annual deduction. An agent doing 10 appointments per week, averaging 30 miles round-trip per appointment, drives approximately 15,600 business miles per year. At the 2025 IRS rate of 70¢/mile, that's a $10,920 deduction — worth roughly $3,700 in combined income and SE tax savings for an agent in the 22% bracket.
The IRS is strict about mileage documentation. A contemporaneous log means recorded at the time of travel, not reconstructed from memory at year-end. Each entry must include:
- Date of trip
- Starting location and destination
- Business purpose (e.g., "Loan signing — 123 Main St, Borrower: John Smith")
- Odometer reading start and end (or miles driven)
Use the mileage tracker in our free Mileage & Expense Tracker tool or a dedicated app (MileIQ, Everlance, TripLog). Your notary journal already records the date, time, and address of every appointment — cross-reference it with your mileage log to make reconstruction nearly bulletproof.
What You Cannot Deduct
- Personal commuting — miles from home to a regular place of business are not deductible. Since most signing agents work from home with no fixed office, this typically isn't an issue, but be aware if you rent office space.
- Personal expenses — clothing (unless a uniform required by a specific client), personal meals (business meals with a specific business purpose are 50% deductible; meals alone are not)
- Fines or penalties — parking tickets, even incurred while traveling to a signing, are not deductible
- Capital expenses not under Section 179 — large equipment that is depreciated must follow IRS depreciation schedules unless you elect Section 179
Quarterly Estimated Taxes
Self-employed signing agents must pay estimated taxes quarterly to avoid an underpayment penalty. The IRS due dates are typically April 15, June 15, September 15, and January 15. A common rule of thumb: set aside 25–30% of every payment you receive into a separate savings account designated for taxes. Use our Tax Savings Calculator to estimate how much your deductions reduce your quarterly tax bill.

The IRS standard mileage rate for business use in 2025 is 70 cents per mile. Verify the current rate at irs.gov as it can change annually. Keep a contemporaneous mileage log — date, destination, purpose, and miles for every business trip. This is mandatory to support the deduction.
Yes, if you use a dedicated space regularly and exclusively for business — printing documents, preparing for appointments, invoicing. The simplified method allows $5 per square foot up to 300 sq ft (max $1,500/year). The regular method uses actual home expenses proportional to the office percentage — potentially larger but more complex to document.
Yes. Under Section 179, you can deduct the full cost of business equipment in the year of purchase rather than depreciating it. A $300 laser printer used exclusively for business is fully deductible in the year you buy it. Keep the receipt and document the business purpose.
Keep receipts or records for every business expense. For mileage: a contemporaneous log with date, destination, purpose, and miles for every trip. For phone and internet: documentation of business-use percentage. For meals: date, attendees, business purpose, amount.
