Mechanics and auto repair shop owners can deduct tools, equipment, vehicle lifts, diagnostic software, shop supplies, uniforms, and business-related vehicle expenses. If you own your shop building, cost segregation unlocks even larger deductions by accelerating depreciation on structural components like service bays, specialized electrical systems, drainage infrastructure, and HVAC—often generating tens of thousands in first-year tax savings.
