The Best Business Tax Deductions You Might Be Missing

When it comes to running a business, every dollar counts. That’s especially true at tax time. Whether you’re a solopreneur, freelancer, small business owner, or managing a growing company, one of the smartest ways to lower your tax bill is by taking advantage of deductions. But here’s the catch—many business owners miss out on valuable write-offs simply because they don’t know what qualifies. Let’s fix that.

In this blog post, we’ll walk you through business tax deductions you might be missing—from everyday expenses to lesser-known strategies that can make a big difference come tax season.

1. Home Office Deduction

If you work from home, even part-time, you may be eligible for the home office deduction—but many business owners overlook it due to confusion about the rules.

To qualify, your home office must be:

  • Your principal place of business

There are two methods to calculate this deduction:

  • Actual expense method: A percentage of your home expenses (utilities, rent/mortgage interest, insurance, maintenance)

If you have a dedicated space, this is a deduction worth taking. Don’t overlook even a small workspace—it adds up over a full year.

2. Startup and Organizational Costs

Did you launch a new business this year? You can deduct up to $5,000 in qualified startup costs and $5,000 in organizational costs in your first year of operation.

Startup costs include:

  • Market research
  • Travel for scouting business locations
  • Training employees
  • Legal and accounting fees before launching

Organizational costs include:

  • Legal fees for forming your business entity
  • State filing fees
  • Consulting fees related to business setup

💡 Anything beyond the $5,000 limits must be amortized over 15 years, but many skip these deductions altogether in the first year—don’t be one of them. It’s a great way to recoup some early investments.

3. Business Use of Your Car

Using your personal vehicle for business purposes? You can deduct:

  • Or actual expenses: Gas, oil, insurance, repairs, depreciation, and more

📌 To qualify, keep a detailed logbook or mileage tracking app that records:

  • Date of each trip
  • Destination and purpose
  • Miles driven

💡 Common business uses include visiting clients, driving to the post office, or attending networking events. These everyday errands can become valuable write-offs when properly tracked.

4. Phone and Internet Expenses

Your smartphone and internet are essential tools—but many people forget to deduct them.

You can write off the percentage used for business. For example:

  • 80% of your phone usage is for client calls? Deduct 80% of your monthly bill.
  • Internet used 50% for business? Deduct half the cost.

💡 Be honest and reasonable about your usage, and document it consistently. Even partial deductions help reduce your tax bill.

5. Professional Services

Working with a:

  • Bookkeeper?
  • Accountant?
  • Business coach?
  • Attorney?

All of these are fully deductible as long as their services are related to your business.

💡 This also includes online platforms and tools you subscribe to for accounting, workflow management, or project collaboration. These costs support your business operations and are 100% deductible.

6. Marketing and Advertising

Promoting your business is not just a good idea—it’s deductible!

This includes:

  • Website development and hosting
  • Social media ads (Facebook, Instagram, LinkedIn, etc.)
  • Print materials (business cards, flyers)
  • Influencer or brand partnerships
  • Photography, video shoots, content creation

💡 Even promotional giveaways or branded swag may qualify. Just ensure your expenses are tied directly to promoting your business.

7. Education and Training

Did you attend a workshop, seminar, online course, or conference related to your business or industry?

You can deduct:

  • Ticket or registration fees
  • Travel and lodging
  • Educational materials

💡 This deduction helps you invest in your professional development while reducing your tax liability. Just make sure the course directly relates to your current business activities.

8. Meals and Entertainment (With Caution)

Business meals are 50% deductible when:

  • You're meeting a client, partner, or potential hire
  • The meal is business-related
  • It’s not “lavish or extravagant”

Always record:

  • Who you met with
  • The purpose of the meeting
  • The amount spent

💡 Entertainment expenses (concerts, sporting events) are not deductible under current tax law, so don’t assume that a night out with a client can be written off.

9. Travel Expenses

Traveling for business? That’s deductible too.

This includes:

  • Airfare, trains, or rental cars
  • Hotel or Airbnb stays
  • Taxi, Uber, Lyft fares
  • Meals (again, 50%)
  • Tips and baggage fees

💡 If your trip is primarily for business, you can deduct travel expenses even if you extend your stay for some personal time. Keep detailed itineraries and separate receipts for business-related expenses.

10. Salaries and Contractor Payments

If you pay employees, freelancers, or independent contractors, those costs are deductible—just make sure you issue:

Also include:

  • Bonuses
  • Commissions
  • Holiday pay
  • Employer contributions to benefits

💡 Labor is one of the most significant business expenses, and these deductions can be substantial.

11. Depreciation

Big purchases like:

  • Equipment
  • Computers
  • Furniture
  • Company vehicles

Can be deducted over time through depreciation or—depending on the item and year—expensed immediately using Section 179 or bonus depreciation.

💡 These tax strategies allow businesses to manage large expenses and maximize deductions over multiple years.

12. Insurance

Did you know you can deduct insurance premiums for business-related coverage?

This includes:

  • Liability insurance
  • Commercial auto insurance
  • Errors and omissions (E&O)
  • Cybersecurity insurance
  • Workers' comp
  • Property insurance

💡 If it protects your business, it likely qualifies. Even premiums for professional liability or malpractice coverage count.

13. Rent or Lease Payments

Do you lease office space, a co-working membership, or rent equipment? All are eligible for deduction.

This includes:

  • Retail or commercial leases
  • Storage units used for inventory or business files
  • Equipment or vehicle leases

💡 If it’s used solely for business, the expense qualifies. Maintain lease agreements and receipts as backup documentation.

14. Bank Fees and Interest

Fees from your business bank account, credit card interest, or payment processing platforms (like Stripe, PayPal, Square) are often overlooked.

These include:

  • Monthly account fees
  • Overdraft fees
  • Loan interest
  • Merchant processing fees

💡 Interest on business credit cards or loans is deductible as long as the funds were used for legitimate business expenses.

15. Bad Debts

If a client or customer fails to pay you and you’ve exhausted your efforts to collect, you might be able to claim it as a bad debt deduction—especially if you're using accrual accounting.

This can apply to product-based businesses and service providers who invoice clients. Document all communication and collection attempts.

16. Office Supplies and Equipment

Paper, pens, toner, mailing supplies, monitors, desks, chairs, external hard drives, webcams—these often qualify for immediate deduction or depreciation depending on their value.

Even software or apps for business use (like Canva Pro, Zoom, Slack) are deductible when used for business. Keep receipts and categorize them correctly in your accounting system.

17. Utilities

Running a physical office space? You can deduct:

  • Electricity
  • Water
  • Heat
  • Garbage disposal
  • Internet and phone lines

💡 These are basic necessities for operating a business and are fully deductible if you're responsible for them under your lease or ownership.

18. Retirement Contributions

Self-employed? Set up a SEP IRA, Solo 401(k), or SIMPLE IRA and deduct contributions made on behalf of yourself (and employees).

You’ll lower your taxable income now while building long-term savings.

For 2025:

  • SEP IRA limit = 25% of compensation up to $70,000
  • Solo 401(k) limit = $23,500 ($30,500 if age 50+) as employee, plus up to 25% of net earnings as employer

19. Health Insurance Premiums

If you're self-employed, you can deduct 100% of health insurance premiums you pay for yourself, your spouse, and dependents.

This applies even if you don’t itemize deductions, as long as your business has a net profit and you aren’t eligible for another plan (like through a spouse).

20. Charitable Contributions (If Applicable)

Businesses structured as C corporations can deduct charitable contributions (up to 10% of taxable income). Other business types (like sole proprietorships or LLCs) may deduct charitable donations on their personal returns if they itemize, but they won’t be considered a business deduction.

Bonus Tip: Keep Great Records

It doesn’t matter how many deductions you qualify for—if you don’t have the receipts, documentation, or proof to back it up, the IRS might not allow them.

💡 Use tools like:

  • Mileage tracking apps like MileIQ
  • Receipt scanners or cloud storage

💡 Keep a separate business bank account and business credit card to make recordkeeping cleaner and easier to track.

Final Thoughts

Tax deductions aren’t just a nice perk—they’re essential for reducing your tax burden and keeping more money in your pocket. But they only work if you know which ones apply and have the records to prove them.

By reviewing this list, you’ve already taken the first step toward maximizing your business deductions. But don’t stop here. Consider working with a trusted tax advisor or accountant who can help you uncover even more savings specific to your business.

Because when it comes to taxes, what you don’t know really can cost you.
