One Big Beautiful Bill (OBBBA)

Quick definition

Federal legislation that made permanent the suspension of unreimbursed employee expense deductions originally introduced by the TCJA.

The One Big Beautiful Bill (OBBBA) made permanent the suspension of unreimbursed employee expense deductions that the Tax Cuts and Jobs Act had set to expire. For W-2 employees, that means the inability to deduct work mileage is no longer a temporary rule.

Why it matters for drivers

Before OBBBA, some W-2 drivers held out hope the unreimbursed-expense deduction would return when the TCJA provisions expired. It will not. The only remedy for an employee is mileage reimbursement from the employer.

Self-employed drivers are unaffected

OBBBA targets the employee deduction. If you file Schedule C as an independent contractor, your business mileage deduction is intact.
