Notary signing agent taxes and deductions

Mileage between signings is the single largest deduction in this trade, and it is the one nobody tracks, because each trip feels too small to write down.

The mileage is the deduction and the tracking is the problem: signings are short trips, and untracked short trips are how thousands of dollars of deduction disappear. Notary fees set by state statute are sometimes treated differently from the signing-agent fee charged on top, so bill them as separate lines.

The deductions with a rule attached

These are the lines where the answer is not simply "keep the receipt"each has a cap, a percentage or a test that decides how much of the spend you actually get:

Mileage between signings: Every drive between signings counts. The rate changed mid-year: 72.5 cents a mile to June 30, 2026 and 76 cents from July 1, so a full year has to be split at that date rather than multiplied by one figure. A hundred business miles a week across the whole year is about $3,861 off your profit. You cannot use the standard rate at all on a vehicle you have already claimed MACRS depreciation, Section 179 or bonus depreciation on.

The rest of the notary signing agent deduction list

Ordinary and necessary business expenses, deductible in full in the year you pay them, provided they are genuinely for the business:

Notary bond
Notary commission fees
Stamps, seals and supplies
Errors and omissions insurance
Background check fees
Notary software

Worth knowing

Mobile notary and loan signing agents: mileage between appointments is the largest deduction. Track every signing trip.

That is what is specific to this trade. The larger deductions are the universal ones, see the full checklist.

What each deduction is worth to you

On $100,000 of profit with no state income tax, $1,000 deducted saves $305, 30.5%, because it comes off self-employment tax and income tax together:

Net profit	Saved per $1,000 deducted	Effective
$40,000	$231	23.1%
$100,000	$305	30.5%
$200,000	$297	29.7%

The last row is worth less than the one above it, and that is not a mistake: past the Social Security wage base the self-employment part of the saving drops from 15.3% to 2.9%, and the higher income-tax bracket does not quite make up the difference. A deduction is worth most in the middle.

Add a state income tax and every row rises. The 1099 calculator applies that layer.

What these words mean

Section 179: A rule letting you deduct the whole cost of equipment in the year you start using it, instead of spreading it over the years you own it.
Depreciation: Spreading the cost of something long-lasting, a vehicle, a camera, a tractor, across the years you use it, rather than deducting it all at once.
MACRS: The standard federal timetable for depreciation, the schedule that decides how much of an asset’s cost you deduct in each year of its life.
