Construction contractors spend a surprising amount of their workday behind the wheel. Between bouncing from one job site to the next, making supply runs, meeting clients for estimates, and picking up permits, mileage tracking for construction contractors is one of the most overlooked tax strategies in the trade. At the 2026 IRS rate of $0.725 per mile, those daily drives can add up to a five-figure deduction.
The catch? You need a proper mileage log to claim it. No log means no deduction if you are ever audited. This guide breaks down exactly which miles count, how the temporary work location rule works in your favor, and the fastest way to build an IRS-compliant record.
Why Construction Contractors Drive So Many Deductible Miles
Most office workers have a single commute. Contractors do not. A typical day might include driving from your home office to a renovation in one zip code, then across town to check on a framing crew, then to the lumber yard for materials, and finally to a client meeting for a new bid.
That pattern easily adds up to 80 to 120 miles in a single day. Over 250 working days, a busy contractor can rack up 20,000 to 30,000 contractor business miles per year. At the current standard mileage rate, that translates to $14,500 to $21,750 in deductions you can write off on your taxes.
The key difference between contractors and many other professions is that nearly every trip is to a different location. You are rarely driving the same route twice. That constant variety is actually an advantage for your construction worker mileage deduction, because almost all of it qualifies as business travel.
Which Miles Are Deductible for Contractors
Not every mile counts. Understanding the line between business vs commuting miles is critical for contractors. Here is a breakdown of what the IRS considers deductible:
Deductible business miles:
- Driving between two or more job sites in a single day
- Trips to supply stores, lumber yards, and equipment rental shops
- Travel to client meetings, estimates, and walk-throughs
- Visits to the permit office or inspection authority
- Drives to your accountant, attorney, or bank for business purposes
- Travel to continuing education, trade shows, or licensing appointments
Not deductible (commuting miles):
- Your first trip from home to your regular place of business
- Your last trip from your regular place of business back home
There is a powerful exception, though. If you work out of a home office that qualifies as your principal place of business, then your first drive to a job site is deductible. The IRS treats your home as the office, making the trip from your door to the first site a business mile rather than a commute.
Tip: Keep a dedicated workspace at home and use it regularly for planning, invoicing, and scheduling. That home office designation can turn your daily commute into a deductible business trip. It is one of the biggest wins for contractors who do admin work from home.
Multi-Site Travel and the Temporary Work Location Rule
The IRS has a rule called the “temporary work location” rule that works heavily in favor of construction contractors. Here is how it applies.
A temporary work location is any place where you realistically expect to work for less than one year. Since most construction projects last weeks or months rather than years, nearly every job site you visit qualifies as temporary. That means your travel between home and those temporary sites is deductible, as long as you also have a regular place of business (like a home office or a shop).
How this plays out in practice:
- You drive from your home office to a kitchen remodel across town (deductible).
- From there, you head to a commercial build-out 15 miles away (deductible).
- You stop at the hardware store for supplies (deductible).
- You drive home at the end of the day (deductible, because your home office is your principal place of business).
Every single mile in that scenario counts. Compare that to a worker who drives to the same office building every day and cannot deduct any of it.
The one exception is a project that lasts longer than one year at the same location. If you are assigned to a single site for 13 months or more, the IRS reclassifies that as a regular work location, and travel to it becomes a non-deductible commute. Keep this in mind for large-scale commercial or infrastructure projects.
How Much Can Contractors Save
The construction mileage tax deduction can be substantial. Here are real numbers based on the 2026 IRS standard mileage rate of $0.725 per mile.
| Annual Business Miles | Standard Mileage Deduction | Estimated Tax Savings (25% bracket) |
|---|---|---|
| 5,000 miles | $3,625 | $906 |
| 10,000 miles | $7,250 | $1,813 |
| 20,000 miles | $14,500 | $3,625 |
| 30,000 miles | $21,750 | $5,438 |
The “estimated tax savings” column reflects income tax only. As a self-employed contractor, you also save on the 15.3% self-employment tax. That means a contractor driving 20,000 business miles could save roughly $5,800 to $6,500 in combined taxes.
Those numbers assume you are claiming mileage on Schedule C using the standard mileage method. You can also use the actual expense method, which tracks contractor vehicle expenses like gas, maintenance, insurance, and depreciation. Most contractors find the standard rate simpler and often more generous, but it is worth running both calculations with your accountant.
Important: The IRS requires "contemporaneous" records. That means you need to log your miles at or near the time of travel, not reconstruct them at the end of the year. A mileage tracking app makes this automatic and eliminates the risk of rejected deductions.
The Easiest Way to Track Construction Miles
Keeping a handwritten mileage log when you are bouncing between three job sites, a supply store, and a client meeting is unrealistic. Most contractors try it for a week and give up. That is exactly where automatic mileage tracking makes the difference.
Tripbook runs in the background on your iPhone and detects trips automatically using GPS and motion sensors. Every drive is recorded with the date, start and end addresses, distance, and driving time. At the end of each day, you simply swipe to classify trips as business or personal. No typing, no forgetting, no spreadsheets.
Here is why automatic tracking works well for contractors specifically:
- Multiple short trips per day - You do not need to remember to start and stop a tracker at every job site. Tripbook catches every trip.
- Offline capability - Construction sites are not always in areas with great cell service. Tripbook works offline and syncs when you have a connection.
- IRS-compliant reports - Export your mileage log as a PDF, CSV, or XLS file that meets IRS documentation requirements. Hand it straight to your accountant at tax time.
- Trip notes - Add the job name or client to each trip so your log clearly shows the business purpose.
If you work in other trades or want to see how mileage tracking for other professions compares, the same principles apply: the more you drive, the more you stand to save.
The bottom line is simple. As a construction contractor, you are leaving thousands of dollars on the table every year if you are not tracking your miles. The IRS gives you a straightforward deduction. You just need the log to prove it.
