Vehicle data: NHTSA vPIC · Tax rules: IRS · Data updated: July 17, 2026
CarLoanCheckup covers one tax break: the car loan interest deduction. It runs for tax years 2025–2028 under Section 70203. This page says plainly what the site is and is not.
Not tax advice
Nothing on this site is tax, legal, or financial advice. We are not CPAs or enrolled agents. Reading a page here does not make us your advisor. Your return turns on facts no website can see: your income and the exact terms of your loan. Before you claim the deduction, take your paperwork to a CPA or an enrolled agent. Get an answer for your own case.
About tool results (estimates)
The VIN checker and the MAGI calculator give estimates. Both run on public data: NHTSA vPIC vehicle records and published IRS rules. An estimate is not an eligibility determination. It does not decide your claim. Only your filed return — and, if it comes to that, the IRS — settles whether your car and your income qualify. No result on this site is a promise of a deduction, a refund, or a dollar amount. Every formula and data field we use is published on the methodology page .
Accuracy and updates
The deduction is new. IRS guidance for the 2025–2028 window is still evolving, and rules can change mid-window. We check irs.gov monthly. Every page carries a "Data updated" date. Still, we make no warranty that any page, or any vPIC record, is complete or current. Blank or wrong vehicle records happen. When the IRS and this site disagree, the IRS wins. Tell us and we fix the page.
Affiliate disclosure
