What Are Home Business Tax Deductions?

Home business tax deductions are expenses related to operating a business from your home that the IRS allows you to subtract from your total income. These deductions reduce your taxable income, meaning you pay less in taxes.

To qualify, your business must meet two basic criteria:

1. Regular and Exclusive Use: A portion of your home must be used regularly and exclusively for conducting business.

2. Principal Place of Business: Your home must be your primary place of business, or where you regularly meet clients or customers.

Benefits of Claiming Home Business Tax Deductions

• Lower taxable income

• Greater cash flow for reinvestment

• Easier bookkeeping and budgeting

• Compliance with IRS regulations (when done correctly)

Top Home Business Tax Deductions to Claim in 2025

Let’s take a closer look at the most common and valuable deductions for home-based businesses.

1. Home Office Deduction

This is one of the biggest tax deductions available. You can deduct a portion of your home expenses based on the percentage of your home used for business.

Two Methods:

• Simplified Option: $5 per square foot (up to 300 sq. ft.)

• Regular Method: Calculates actual expenses (e.g., utilities, rent, repairs) based on business-use percentage.

Tip: Document your home office with photos and floor plans in case of an audit.

2. Internet and Phone Bills

You can deduct the percentage of your internet and phone usage that is for business. If you have a separate business line or dedicated internet, you can deduct it entirely.

• Example: If you use your home internet 60% for business, you can deduct 60% of the bill.

3. Utilities

Electricity, heating, gas, water, and trash removal can all be partially deductible under the home office deduction if used in your work area.

4. Mortgage Interest or Rent

• If you own your home, a portion of your mortgage interest (not principal) may be deductible.

• If you rent, you can deduct the percentage of your rent that applies to your home office space.

5. Depreciation of Your Home

This allows you to deduct a portion of the cost of your home over time. Depreciation applies if you own your home and use part of it for business.

Note: Depreciation may affect the capital gains tax when selling your home later, so consult with a tax professional.

6. Office Supplies and Equipment

• Paper, pens, notebooks, and printer ink

• Business software subscriptions (e.g., QuickBooks, Canva, Adobe Suite)

• Computers, printers, and other electronics used solely for business

7. Furniture and Fixtures

Any furniture you purchase and use for your business (desk, chair, filing cabinet) may be eligible. Items over a certain price may need to be depreciated rather than fully deducted.

8. Business Insurance

If you have liability or property insurance for your home-based business, it’s deductible. Homeowner’s insurance may also be partially deductible under the home office deduction.

9. Advertising and Marketing

Include expenses like:

• Website domain and hosting

• Social media advertising

• Print or digital ads

• Email marketing platforms

10. Professional Services

Fees paid to:

• Accountants

• Business consultants

• Lawyers

• Tax preparers

These are fully deductible business expenses.

11. Education and Training

If you take online courses, attend webinars, or purchase books relevant to your business, these are considered legitimate expenses.

Example: A graphic designer taking a Photoshop course can deduct the cost.

12. Travel and Mileage

Even for home businesses, you may need to meet clients, attend trade shows, or run errands.

• Standard Mileage Rate (2025): Check IRS.gov for updated mileage rates.

• Keep a log of business trips with dates, purposes, and miles driven.

13. Startup Costs

If your home business is new, you can deduct up to $5,000 of startup expenses in your first year, including:

• Market research

• Equipment purchases

• Legal fees for business formation

14. Bank Fees and Interest

• Monthly service fees from business accounts

• PayPal or Stripe transaction fees

• Business loan interest

15. Repairs and Maintenance

Repairs made exclusively to your home office (e.g., fixing your office window or repainting your workroom) are fully deductible. General home repairs may be partially deductible.

What You Can’t Deduct

• Personal expenses not related to the business

• Double-dipping (e.g., claiming a full internet bill when it’s partly for personal use)

• Lunch with friends (unless it’s a business meeting with documentation)

Tips for Maximizing Your Deductions

1. Separate Business and Personal Finances
   Open a dedicated business bank account and credit card.

2. Track Everything
   Use apps like QuickBooks, FreshBooks, or Wave to record expenses.

3. Keep Receipts and Proof
   Scan receipts and back up digital copies in case of an IRS audit.

4. Consult a Tax Professional
   A CPA familiar with home businesses can help you optimize your deductions and avoid red flags.
