Tag every case to a dentist
As an HVAC contractor, accurately tracking and deducting service van expenses is crucial for tax compliance. Here's how to do it:
When it comes to tracking mileage and expenses, it's essential to tag every case to a dentist. This means assigning a unique identifier to each service van and tracking the mileage and expenses separately. This is because the IRS has specific rules for tracking mileage, which vary by type of vehicle.
To claim this deduction, you must meet certain requirements, including that the van be used for business purposes and that the mileage be tracked and verified.
To tag a case to a dentist, follow these steps:
- Assign a unique identifier to each service van, such as a VIN or a serial number.
- Use a mileage tracker or spreadsheet to record the mileage and expenses for each van.
- Make sure to keep records of the mileage and expenses, including receipts and bank statements.
- Use a standardized format for tracking mileage and expenses, such as a mileage log or a spreadsheet template.
- Verify the mileage and expenses regularly to ensure accuracy.
- Keep records of the tagged cases for at least three years in case of an audit.
By following these steps, you can accurately track and deduct your service van expenses, maximizing your deductions and ensuring compliance with IRS rules.
Track mileage and expenses
Here is the section on "Track mileage and expenses":
- Determine the correct mileage rate for your business. From January 1 to June 30, 2026, the rate is 72.5 cents per mile. From July 1 to December 31, 2026, the rate is 76 cents per mile. You can find the standard mileage rates for each quarter on the IRS website.
- Keep track of the number of miles driven for each business-related service. This will help you accurately calculate the mileage expenses. You can use a log or a spreadsheet to keep track of the miles.
- Calculate the total miles driven for the business. This can be done by adding up the miles driven for each service or by using a mileage log. The total miles driven should be recorded in the calendar quarter for which the rate applies.
- Determine the business's actual expenses for fuel and maintenance. You can also use a mileage log to record the actual expenses.
- Calculate the business's actual mileage expenses.
- Calculate the business's business use percentage. This can be done by dividing the total miles driven by the total miles driven for the business.

Choose the right method
If you qualify for both methods, calculate your deduction using both to determine which yields a larger deduction. Generally, you must choose the standard mileage rate in the first year the car is used for business if you own it.
Record keeping and documentation
Adequate records are crucial for both mileage logs and moving expense deductions. Specifically, keep records for mileage logs if using the standard mileage rate. This includes the odometer reading at the beginning and end of each log period, as well as the dates and types of business miles traveled. You can also include a copy of the log with the contractor's expenses, along with a description of the miles driven and the business purpose of the trip.
For mileage logs, it's recommended to use a spreadsheet or accounting software that allows you to easily track and organize your data. Consider using a format with columns for date, business miles, driver name, and mileage rate. When using the standard mileage rate, you can calculate the total mileage cost by multiplying the rate by the total number of miles driven.
Moving expenses are generally suspended for most taxpayers after 2017, except for active-duty members of the U.S. Armed Forces moving under official orders. If you're using the moving expense method, make sure to keep records of the following:
- The date and type of moving expense (e.g., moving truck rental, packing supplies, etc.)
- The cost of the expense
- A copy of the expense receipt or invoice
- A description of the business purpose of the expense
When it comes to documentation, keep it accurate and complete. Make sure to include all relevant information, such as the odometer reading, dates, and types of business miles traveled. Keep records for at least 3 years in case of an audit.
Maintain accurate records
As an HVAC contractor, accurately tracking fuel and maintenance expenses is crucial for tax purposes. To do this, follow these steps:
- Keep a logbook or spreadsheet to record each fuel and maintenance expense, including the date, mileage, and type of fuel used.
- Include details on the fuel used, such as the type (gasoline or diesel) and the number of gallons consumed. You can also note the route taken, if applicable.
- Keep records of maintenance expenses, such as repairs, replacements, and supplies. These can include costs for parts, labor, and other expenses related to maintaining your service vans.
- Keep receipts for all fuel and maintenance expenses, including any receipts for fuel purchased or used. These can be used to track your expenses and calculate your deductions.
- This can vary depending on the complexity of your business and the type of expenses you claim.
- To ensure accuracy, double-check your records by comparing them to your receipts and odometer logbook. This will help prevent errors and ensure that you're taking advantage of all eligible deductions.
