15 Tax Deductions Your Small Business Is Probably Missing

Most small business owners overpay on taxes, not because they earn too much, but because they don't claim what they're already entitled to. The IRS allows you to deduct legitimate business expenses from your taxable income. But you have to know they exist, and you have to document them.

Here are 15 deductions that consistently go unclaimed.

1. Home Office

If you use part of your home exclusively and regularly for business, that space is deductible. The key word is "exclusively." It can't double as a guest bedroom or TV room.

Two methods:

• •Simplified method: $5 per square foot, maximum 300 sq ft = up to $1,500 deduction. No depreciation tracking required.
• •Actual expenses method: calculate the percentage of your home used for business and apply it to actual rent or mortgage interest, utilities, insurance, and maintenance. More paperwork, but higher deduction for large dedicated spaces.

2. Vehicle Mileage

Every mile driven for a legitimate business purpose is deductible. The IRS standard mileage rate for 2024 is 67 cents per mile (check the updated 2026 rate at irs.gov).

Keep a mileage log with: date, destination, business purpose, and miles driven. Apps like MileIQ or Everlance automate this entirely.

Also: parking fees and tolls are 100% deductible separately, even if you use the standard mileage rate.

3. Cell Phone

Only the business-use percentage is deductible. If you use your phone 60% for business, you can deduct 60% of your monthly bill. Keep records of business calls if you're ever questioned.

If you have a phone used exclusively for business, it's 100% deductible.

4. Internet Service

Apply the same percentage logic as your phone. If you use your home internet for work, calculate the business-use percentage and deduct that portion. A dedicated business internet line is 100% deductible.

5. Equipment and Technology

Computers, printers, cameras, tools, specialized equipment: anything you use in your business is deductible.

Section 179 lets you deduct the full purchase price of qualifying equipment in the year you buy it, rather than depreciating it over several years. The 2024 limit is $1,050,000, well beyond what most small businesses spend.

6. Software and Subscriptions

Adobe Creative Cloud, QuickBooks, Canva, Zoom, your CRM, project management tools, email marketing platforms, industry databases: 100% deductible if used for business.

Go through your bank and credit card statements. You'll likely find subscriptions you've been paying for but haven't been claiming.

7. Self-Employed Health Insurance

This is one of the most valuable and most overlooked deductions. As a self-employed individual, you can deduct 100% of the premiums you pay for health insurance for yourself, your spouse, and your dependents.

The deduction comes off your gross income directly (not just business income), which makes it unusually powerful. It's subject to income limitations; you can't deduct more than your business net profit.

8. Retirement Contributions

Saving for retirement reduces your tax bill right now:

• •SEP IRA: up to 25% of net self-employment income, maximum $69,000 for 2024. The simplest to open and fund.
• •Solo 401(k): up to $23,000 as the employee + 25% employer match. Allows the highest contributions if your income is high.

Every dollar you contribute is a dollar off your taxable income. It's the rare case where saving for yourself also saves you money today.

9. Marketing and Advertising

Your website, hosting, domain, Facebook and Instagram ads, Google Ads, business cards, flyers, logo design, SEO services, and professional photography are all 100% deductible.

If you pay a freelancer to create content, manage your social media, or run your ad campaigns, that's fully deductible as a marketing expense.

10. Education and Training

Courses, books, certifications, workshops, and conferences are deductible when they directly relate to your current business. The key: it must improve skills in the work you already do, not train you for an entirely new career.

A contractor taking an advanced construction course: deductible. That same contractor taking a course to become a real estate agent: not deductible.

11. Professional Services

Accountant fees, attorney fees, business consultant fees: any professional service hired for business purposes is 100% deductible. That includes your tax preparation fees, for the portion that relates to your business.

12. Business Meals (50%)

Meals with clients, partners, or vendors where business is discussed are 50% deductible. Note: entertainment expenses (concerts, sporting events) are no longer deductible since the 2018 Tax Cuts and Jobs Act. Only the meals themselves qualify.

Requirements: keep the receipt, note who was present and what business topic was discussed. A quick note on the receipt or a photo with a brief caption is all you need.

13. Business Travel

Trips taken primarily for business are deductible: flights, hotels, rental cars, local transportation. If you mix business and personal travel, only the business portion is deductible.

Meals during business travel are deductible at 50%.

Practical tip: if you attend a three-day conference and stay an extra day to sightsee, the three business days are deductible. The personal day is not.

14. Vehicle Actual Expenses (Alternative to Mileage)

Instead of taking the standard mileage rate, you can deduct your actual vehicle expenses: gas, insurance, maintenance, repairs, and depreciation, multiplied by the percentage of business use.

This method often works better for expensive vehicles or situations where business use is very high. You must choose your method in the first year you use the vehicle for business, and switching later is restricted.

15. Bank Fees and Payment Processing

Your business bank account fees, PayPal or Stripe processing fees (typically 2.9% + $0.30 per transaction), wire transfer fees, and currency conversion fees are all 100% deductible.

If you process $150,000 per year through Stripe at 2.9%, that's $4,350 in fees. Make sure you're claiming it.

The System That Makes It Easy

Knowing the deductions is only half the battle. The other half is being organized enough to actually claim them.

Open a dedicated business bank account and credit card. Every business expense goes through those accounts. Nothing else. At tax time, your statements are essentially a ready-made expense report.

Categorize monthly, not annually. Thirty minutes per month beats eight hours every April. Most accounting software (QuickBooks, Wave, FreshBooks) does most of the categorization automatically once you've set it up once.

Work with a professional who understands self-employment. A generalist preparer may miss deductions specific to your industry. The difference in what they find can easily exceed their fee several times over.

What the Numbers Look Like

Say you have $80,000 in gross business income and you correctly document $20,000 in deductions: home office, mileage, software, health insurance, and a SEP IRA contribution.

Your taxable net income drops to $60,000. At a 22% federal bracket, that's $4,400 less in income tax. Plus, SE tax on $20,000 less income saves roughly another $3,060. Total savings: approximately $7,460, just for tracking what you were already spending.

Your Deductions Already Exist

You're not inventing expenses. You're documenting ones that are already happening. The difference between what you pay now and what you should be paying is largely a record-keeping problem, and one that's easy to fix.
