Tax Strategy for notary publics
A notary's two core costs are the state commission renewal fee and the required journal, seal, and insurance. These are fully deductible and are easy to overlook precisely because they are small and routine. Notaries who also perform loan signing add document preparation time, mobile-notary travel mileage, and business insurance to the deduction schedule.
Mobile notary work is often the higher-margin and more seasonal part of the trade, with signing volume tied to the home purchase cycle. Loan-signing income can appear in a single month and then vanish for a quarter, so divide the trailing-twelve-month total rather than extrapolating a strong signing month.
To avoid underpayment penalties, pay at least 90% of your current-year tax, or 100% of last year's total tax — 110% if your prior-year AGI was above $150,000.
