Are Car Registration Fees Tax Deductible in Montana?
Short answer: Sometimes: only the county option tax (where adopted) is value-based, and it's deductible if you itemize. Counties may levy up to 0.7% of depreciated MSRP; the state registration fee itself is age-based and not deductible.
Listed as county option tax on your MVD renewal, only if your county levies a value-based rate rather than a flat fee. The deductible part counts toward the $40,400 SALT cap.
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.
