Tax Deductions for Notary Publics

Business Insurance

Premiums for professional liability (E&O), general liability, and business property insurance are deductible. This includes malpractice insurance for licensed professionals.

Line 15 - Insurance (other than health)Publication 535

Mileage / Vehicle Expenses

Business miles driven can be deducted using the standard mileage rate (67 cents/mile for 2024) or actual expenses (gas, insurance, repairs, depreciation). You must keep a mileage log.

Line 9 - Car and truck expensesPublication 463

Pro Tip: The standard mileage rate is simpler, but actual expenses may yield a larger deduction for expensive vehicles. You must choose one method in the first year you use the car for business.

Phone & Internet

The business-use percentage of your cell phone bill and internet service is deductible. If you use your phone 70% for business, you can deduct 70% of the bill.

Line 25 - UtilitiesPublication 535

Pro Tip: Keep a log for one representative month showing business vs. personal usage to establish your percentage.

Advertising & Marketing

Costs for promoting your business are deductible, including website hosting, social media ads, business cards, flyers, SEO services, and online directory listings.

Home Office Deduction

If you use part of your home regularly and exclusively for business, you can deduct a portion of rent/mortgage, utilities, and insurance. The simplified method allows $5/sq ft up to 300 sq ft ($1,500 max).

Line 30 - Business use of homePublication 587

Pro Tip: The simplified method is easier but caps at $1,500. If your actual expenses exceed that, use the regular method and keep records of all housing costs.

Software & Subscriptions

Business software, SaaS subscriptions, cloud storage, and professional tools are deductible in the year paid. This includes accounting software, project management tools, and industry-specific apps.

Education & Professional Development

Courses, workshops, books, and conferences that maintain or improve skills in your current profession are deductible. The education must relate to your existing trade.

Line 27a - Other expensesPublication 970

Pro Tip: Education that qualifies you for a new profession is NOT deductible as a business expense, even if it's related to your field.

Retirement Contributions (SEP-IRA / Solo 401k)

Self-employed individuals can contribute to a SEP-IRA (up to 25% of net SE earnings, max $69,000 for 2024) or Solo 401(k) with employee + employer contributions.

Form 1040, Schedule 1, Line 16Publication 560

Pro Tip: A Solo 401(k) lets you contribute more at lower income levels because of the employee elective deferral ($23,000 for 2024 + catch-up if 50+).
