Additional Business Deductions — Overlooked Tax Breaks for Home-Business Owners (2025)
Beyond the major deductions like home office, vehicle expenses, and retirement plans,
the tax code offers dozens of lesser-known deductions that home-business owners often miss.
This guide covers advertising, professional fees, subscriptions, education, bank fees, software, and more —
all based on 2025 IRS rules and industry standards.
1️⃣ Advertising & Marketing Expenses
Chapter 14 confirms that advertising and marketing are fully deductible when ordinary and necessary
for your home business. This includes both digital and traditional forms of outreach.
- ✔️ Social media ads
- ✔️ Google Ads & SEO services
- ✔️ Business website hosting & design
- ✔️ Flyers, printing, and business cards
- ✔️ Sponsored content or influencer fees
Tip: Website costs are deductible each year — not depreciated.
2️⃣ Professional Services & Fees
Fees paid to professionals are fully deductible as business expenses.
- ✔️ Tax preparation (business portion)
- ✔️ Legal fees
- ✔️ Bookkeeping & payroll services
- ✔️ Consulting fees
- ✔️ Industry-specific professionals (design, editing, technology)
3️⃣ Education & Training
Education is deductible only when it improves or maintains skills in your current business — not when it qualifies you for a new profession.
- ✔️ Online courses
- ✔️ Professional certifications
- ✔️ Webinars & workshops
- ✔️ Books related to your business
💡 Example
A freelance photographer buys a $300 online editing course.
