Doing your taxes might not be the most exciting thing about running a contracting business, but getting them right can save you thousands of dollars every year.

A service contracting business comes with a long list of expenses, but the good news is that many of them can be deducted from your taxable income—helping you keep more of your hard-earned money. 

However, many contractors miss out on valuable deductions simply because they don’t know about them or fail to keep proper records.  

‍

Below, we’ll cover the most important tax deductions for service contractors, including some that are often overlooked.   

‍

1. Vehicle Expenses – Don’t Miss the Miles!  

If you use a vehicle for your contracting business—whether it’s a van loaded with tools or a pickup truck for job site visits—you can deduct costs like fuel, insurance, and even depreciation. 

The IRS allows two ways to claim vehicle deductions: the standard mileage rate (which changes yearly) or the actual expenses method. Keep a mileage log to track work-related driving, as even short trips to pick up supplies or visit clients add up.

‍

‍

And don’t forget about vehicle maintenance costs. Oil changes, new tires, repairs, and even a portion of your auto loan interest (if the vehicle is financed) can be written off. The key is to separate personal and business use—a dedicated work truck is the easiest way to track everything correctly.  

‍

2. Tools and Equipment – If You Need It, You Can Deduct It  

‍

Every contractor needs tools, and luckily, most equipment purchases are deductible. If the cost is under a certain threshold (e.g., $2,500 in the U.S.), you can write off the full amount in the same year. For more expensive equipment, you may need to depreciate it over time.  

‍

‍

Even small purchases add up. Items like drills, ladders, safety gear, and even software for estimating jobs or managing schedules can be deducted. The key is keeping receipts and categorizing expenses properly to avoid headaches at tax time.  

‍

3. Home Office Deduction – Don’t Skip It If You Qualify  

‍

If you use part of your home exclusively for business—whether it’s an office for managing schedules or a workshop for prepping materials—you may qualify for the home office deduction. This lets you write off a portion of your rent/mortgage, utilities, and even internet costs.  

Even if you mainly work on job sites, your home office still counts if you regularly use it for administrative tasks. The simplified method allows a $5 per square foot deduction (up to 300 square feet) without complicated calculations.  

‍

4. Insurance Costs – Protect Yourself and Lower Your Taxes  

‍

Contractors typically carry several types of insurance—general liability, workers' compensation, commercial auto, and even professional liability. All of these are tax-deductible since they’re necessary for running your business.  

Health insurance for yourself and your employees is also deductible. If you’re self-employed, you can claim 100% of your health insurance premiums as an adjustment to income—not just an itemized deduction.  

‍

5. Marketing and Advertising – Every Dollar Counts  

‍

Whether you run Facebook ads, print flyers, or pay for a professional website, marketing expenses are fully deductible. Even small things like branded shirts, truck decals, and business cards can be written off.  

Networking events, sponsorships, and even referral bonuses count as marketing expenses. If you’re spending money to attract customers, make sure you’re getting the tax benefits too.  

‍

6. Education and Training – Invest in Your Skills and Save  

‍

Any training, certifications, or courses that improve your skills and help you run your business can be deducted. This includes trade certifications, OSHA safety courses, or even a business management class.  

Industry conferences, books, and even some online subscriptions (if related to your trade) qualify. Keep documentation of how the expense is business-related to avoid IRS issues.  

‍

7. Subcontractor and Employee Wages – Big Deduction, Big Responsibility  

‍

If you hire employees or subcontractors, their wages are fully deductible. Make sure you properly classify workers—1099 contractors vs. W-2 employees—to stay compliant with tax laws.  

Payroll taxes, benefits, and even bonuses are deductible too. If you’re paying people to help grow your business, don’t forget to claim these expenses.  

‍

Keep Good Records and Maximize Your Deductions  

‍

The best way to ensure you get all the deductions you deserve is keeping detailed records. Use accounting software, track receipts, and set aside time to review expenses regularly. A little effort throughout the year saves big money at tax time.  

Please make sure to consult a CPA when filing taxes to make sure you can deduct anything mentioned here. Deductions vary based on the exact company or individual situation or circumstance.

‍

Bottom line? Don’t leave money on the table. The tax system rewards business owners who track their expenses wisely—so make sure you’re one of them.
