Important: This estimator provides a general illustration for U.S. taxpayers regarding the business use of an auto loan and is for informational purposes only. It is NOT tax advice. Tax laws are complex and subject to change. This tool only considers loan interest and does not cover other potential deductions (e.g., depreciation, operating expenses under the actual expense method, or the standard mileage rate rules) which have specific requirements. Always consult with a qualified tax professional for advice tailored to your specific financial situation and current tax regulations before making any tax-related decisions.
