Smog check

$30-$70

Can You Write Off Smog Check?

Short answer: No: smog and emissions tests on a personal car aren't deductible.

Business vehicles can deduct them as an operating cost.

Records to keep: Keep receipts, statements (1098, 1098-T, 1099, W-2G), and a note of what each cost was for. Compare itemizing to the 2026 standard deduction before you claim.
