What is the IRS standard mileage rate this year?
The 2025 IRS standard mileage rate for business use is 70 cents per mile, up from 67 cents in 2024. The IRS adjusts this annually based on fuel costs, insurance, depreciation, and general vehicle operating expenses.
To calculate your deduction, multiply the rate by the number of business miles you drove during the year. If you drove 20,000 business miles, that’s a $14,000 deduction. For contractors and trades businesses driving between job sites, supply houses, and client meetings every day, the numbers add up fast.
The standard mileage rate is one of two options. The other is the actual expense method, where you track every cost tied to the vehicle and deduct the business-use percentage. Gas, oil changes, tires, insurance, registration, repairs, and depreciation all get factored in. The actual expense method sometimes produces a larger deduction for heavy-duty trucks and work vehicles that are expensive to maintain. But it requires a lot more recordkeeping.
There’s one important rule about switching between methods. If you use the standard mileage rate in the first year you put a vehicle into business service, you can switch to actual expenses later. But if you start with actual expenses using MACRS depreciation, you’re locked out of the standard mileage rate for that vehicle going forward. Worth thinking about before you commit.
Regardless of which method you choose, the IRS requires a log of your business miles. Each entry needs the date, destination, business purpose, and miles driven. Apps like MileIQ or the QuickBooks mileage tracker handle this automatically. A notebook in the truck works too, as long as you actually fill it out consistently.
Driving between job sites counts as business mileage. Trips to pick up materials count. Meeting a client for an estimate counts. Your commute from home to your regular first stop generally does not count, unless your home office qualifies as your principal place of business.
This is one of the most commonly missed deductions for skilled trades businesses. Thousands of miles driven throughout the year with no log to support the deduction means you’re paying taxes on money you didn’t need to. If your books are already behind or you’re not sure whether you’re capturing mileage properly, contractor bookkeeping services can help you get a system in place so nothing falls through the cracks at tax time.

The simplest approach is the safe harbor method. Pay 100% of last year's total tax liability divided by four (110% if your AGI exceeded $150,000). This avoids underpayment penalties regardless of what you end up owing.

Start with a construction-specific chart of accounts, enable Projects for job costing, and build out your items list to match how you estimate and invoice. Generic setup won't give you the reporting contractors actually need.

Set up each client as a sub-customer or project in your accounting software so every invoice and expense ties back to a specific account. Use recurring invoices for regular clients and review profitability per account monthly.
