Episode #2
Self-Employed and the Vehicle Loan Interest Deduction
The new deduction for qualifying vehicle loan interest sounds straightforward enough — until the taxpayer is self-employed and uses the vehicle for business. In this episode of Accounting in the Wild , Jason Dinesen takes a practical look at how the new vehicle loan interest deduction works when a vehicle has both personal and business use. A key issue is whether the vehicle qualifies as a personal-use vehicle in the first place. Under the final regulations, that determination is based on the taxpayer’s intended use at the time the vehicle is purchased . If the taxpayer intends to use the vehicle more than 50% for personal purposes, it can qualify even if the actual business-use percentage later turns out to be higher. From there, self-employed taxpayers have some flexibility. Jason walks through the regulations’ examples showing how qualifying interest can potentially be deducted entirely on Schedule 1A or allocated between Schedule 1A and Schedule C based on actual business use. The episode also explores an important wrinkle: the $10,000 limitation applies to the Schedule 1A deduction, not to the portion properly deducted on Schedule C . That can make allocation particularly important when the taxpayer has substantial vehicle-loan interest. Topics include: What makes a vehicle a qualifying personal-use vehicle Why the taxpayer’s intent at the time of purchase matters What happens when actual business use differs from expected use Allocating interest between Schedule 1A and Schedule C How the $10,000 limitation interacts with business-use interest Practical examples from the final regulations For tax professionals working with sole proprietors and other self-employed taxpayers, this episode breaks down an easily overlooked intersection between a new individual deduction and familiar business vehicle rules.
