11 Tax Deductions Every Contractor Should Know in 2026<\/h1>\n

You Are Probably Leaving Money on the Table<\/h2>\n

Picture this. It is April, and you are sitting at your kitchen table with a shoebox of receipts, a stack of bank statements, and a growing sense of dread. Your accountant asks about mileage. You shrug. They ask about the home office. You say “I work out of my truck.” They move on.<\/p>\n

And just like that, you paid the IRS a few thousand dollars more than you needed to.<\/p>\n

It happens to contractors every single year. You are great at your trade, but the tax code was not written for people who swing hammers. It was written by people who sit behind desks. So the deductions that apply to you are scattered across a dozen different IRS publications, and unless someone lays them out clearly, they are easy to miss.<\/p>\n

\n
WHY THIS MATTERS<\/div>\n

The average self-employed contractor pays an effective tax rate between 25% and 35% when you include self-employment tax. Every legitimate deduction you miss is money straight out of your pocket. A contractor doing $200,000 in revenue who misses just $15,000 in deductions is overpaying by roughly $4,500 to $5,250 in taxes.<\/p>\n<\/div>\n

This guide covers the 11 deductions that matter most for contractors in 2026. Not theory. Not accounting jargon. Practical, real-world write-offs with dollar amounts and examples so you can have a smarter conversation with your CPA, or handle things yourself with confidence.<\/p>\n

1. Vehicle and Mileage Expenses<\/h2>\n

Your truck is your office, your supply run vehicle, and your job-to-job shuttle. For most contractors, vehicle expenses are the single largest deduction they claim, and also the one they most often under-track.<\/p>\n

Two Methods, One Choice<\/h3>\n

The IRS gives you two options for deducting vehicle expenses:<\/p>\n

Standard Mileage Rate:<\/strong> For 2026, the IRS standard mileage rate is $0.725 per mile. If you drive 25,000 business miles in a year, that is $18,125 in deductions without tracking a single gas receipt.<\/p>\n

Actual Expense Method:<\/strong> Track every cost: gas, insurance, repairs, tires, oil changes, registration, depreciation. Then multiply by the percentage of miles driven for business. If 80% of your 30,000 total miles were business, you deduct 80% of all vehicle costs.<\/p>\n

Which is better? It depends on your truck and how much you drive. A newer, expensive truck with high payments often favors actual expenses. An older, paid-off truck usually favors the standard rate. Run both numbers or have your CPA compare.<\/p>\n

\n
REAL EXAMPLE<\/div>\n

A plumber in Houston drives 28,000 business miles per year. At $0.725\/mile, that is $20,300 in deductions<\/strong>. At a 30% combined tax rate, that saves $6,090<\/strong> in taxes. But only if they tracked the mileage. Forgetting to log those miles means writing a $6,000 check to the IRS that they did not owe.<\/p>\n<\/div>\n

The Tracking Problem<\/h3>\n

Here is where most contractors lose this deduction: they do not track consistently. You need a mileage log that shows the date, starting location, destination, business purpose, and miles driven. Every trip. All year.<\/p>\n

Nobody does that with a notebook. That is why apps exist. SimplyWise<\/a> includes a mileage tracker that runs in the background and logs your drives automatically. At the end of the year, you export the log and hand it to your accountant. Done.<\/p>\n

Important:<\/strong> You cannot use the standard mileage rate if you have already claimed depreciation on the vehicle using a method other than straight-line, or if you use five or more vehicles simultaneously. Check IRS Publication 463 for the full rules.<\/p>\n<\/div>\n<\/div>\n

2. Tools and Equipment (Section 179)<\/h2>\n

Every saw, drill, compressor, laser level, and generator you buy for work is deductible. But the way you deduct them depends on the cost and how you choose to handle it.<\/p>\n

Section 179 Deduction<\/h3>\n

Section 179 lets you deduct the full purchase price of qualifying equipment in the year you buy it, instead of depreciating it over several years. For 2026, the deduction limit is $2,560,000, with a spending cap of $4,090,000 before the deduction begins to phase out. For most contractors, you will never hit those limits, so everything qualifies for immediate deduction.<\/p>\n
