How do I deduct can you write off gas to work on my taxes?

TL;DR

Gas expenses for commuting to and from your regular place of work are generally not deductible. However, if you use your vehicle for business purposes beyond commuting, those expenses may be deductible.

Detailed Answer

Gas expenses incurred while commuting from your home to your regular place of business are considered personal commuting expenses and are not deductible. However, if you are a small business owner, freelancer, or independent contractor using your vehicle for business purposes, such as traveling between job sites, meeting clients, or running business errands, you can deduct the gas expenses. You can choose to deduct actual expenses, which include gas, or use the standard mileage rate set by the IRS. For 2023, the standard mileage rate is 65.5 cents per mile. It's important to keep detailed records of your business mileage and separate it from personal use.

Where to Put It on the Tax Form

Schedule C, Line 9 for car and truck expenses. If using actual expenses, Form 4562 may also be required.

Real World Example

A freelance graphic designer drives to meet clients and attend networking events. She logs 3,000 business miles in 2023. Using the standard mileage rate, she can deduct $1,965 (3,000 miles x $0.655) on her Schedule C.

Calculation Required

A calculation is required for this deduction.

To calculate the deduction using the standard mileage rate, multiply the total business miles driven by the IRS mileage rate (e.g., 3,000 miles x $0.655). For actual expenses, calculate the percentage of business use and apply it to total vehicle expenses, including gas.

Audit Risk & Documentation Tips

Moderate audit risk. Keep a detailed mileage log with dates, destinations, and purpose of each trip. Retain receipts for gas and maintenance if deducting actual expenses. Use apps or a physical logbook to ensure accuracy and completeness.
