Car registration fees in Idaho

Varies

Are Car Registration Fees Tax Deductible in Idaho?

Short answer: No: Idaho doesn't base registration on your car's value, so it isn't deductible as personal property tax. Passenger vehicles pay $69 (1-2 years old), $57 (3-6 years) or $45 (7+ years) per year regardless of value.

Only annual taxes based on a vehicle's value are deductible (IRS Topic 503); sales tax paid when you buy a car can count if you deduct sales tax instead of state income tax.

Records to keep: Keep receipts, statements, and a note of what each cost was for. Compare itemizing to the 2026 standard deduction ($16,100 single / $32,200 joint) before you claim.
