Is Car Loan Interest Tax Deductible in 2026? Check Eligibility and Your Deduction

A new, temporary deduction for 2025–2028: up to $10,000 of interest on a qualifying new-vehicle loan, claimed on Schedule 1-A whether or not you itemize. Seven statutory requirements decide eligibility — answer them below, then let the engine size your deduction and its income phase-out.

Eligibility check, then your deduction

Example: single, $112,500 MAGI, $10,000 interest paid, all seven requirements met → 13 × $200 phase-out = −$2,600, leaving a $7,400 deduction.

1. New vehicle

Original use starts with the taxpayer — used vehicles never qualify.

2. Personal use

Business/commercial use is excluded.

3. Qualified vehicle type

Car, minivan, van, SUV, pickup, or motorcycle; at least 2 wheels; GVWR under 14,000 lbs; made for public roads.

4. Final assembly in the U.S.

Establish via the VIN plant-of-manufacture (49 CFR 565; NHTSA VIN Decoder at nhtsa.gov/vin-decoder) or the vehicle information label (49 CFR 583.5(a)(3)).

5. Qualified loan

Originated after 12/31/2024, purchase-money, secured by a FIRST lien on the vehicle. Refinances qualify up to the refinanced principal if still first-lien.

6. No exclusions apply

Leases (lease payments never qualify), fleet/commercial use, salvage-title and scrap/parts vehicles, and related-party loans (§§267(b)/707(b)(1)) are excluded.

7. VIN reported on the return

Reporting the VIN on the return is a statutory condition.

Answer the seven eligibility questions, then enter your MAGI and interest paid for the verdict and deduction.

The seven requirements, straight from the statute

Eligibility under IRC §163(h)(4) is all-or-nothing — every requirement below must hold, and the calculator's verdict comes from the same engine that computes the dollar amounts:

  1. New vehicle. Original use starts with the taxpayer — used vehicles never qualify.
  2. Personal use. Business/commercial use is excluded.
  3. Qualified vehicle type. Car, minivan, van, SUV, pickup, or motorcycle; at least 2 wheels; GVWR under 14,000 lbs; made for public roads.
  4. Final assembly in the U.S.. Establish via the VIN plant-of-manufacture (49 CFR 565; NHTSA VIN Decoder at nhtsa.gov/vin-decoder) or the vehicle information label (49 CFR 583.5(a)(3)).
  5. Qualified loan. Originated after 12/31/2024, purchase-money, secured by a FIRST lien on the vehicle. Refinances qualify up to the refinanced principal if still first-lien.
  6. No exclusions apply. Leases (lease payments never qualify), fleet/commercial use, salvage-title and scrap/parts vehicles, and related-party loans (§§267(b)/707(b)(1)) are excluded.
  7. VIN reported on the return. Reporting the VIN on the return is a statutory condition.

The final-assembly requirement deserves honesty: check your VIN or window sticker — the statute requires U.S. final assembly, and neither the badge on the hood nor the dealer's word settles it. The NHTSA VIN Decoder reads the plant of manufacture from the VIN (49 CFR 565); the vehicle information label required by 49 CFR 583.5(a)(3) states it outright.

The phase-out is a staircase, not a slope

Below the thresholds there is nothing to phase out: a single filer at $90,000 MAGI with $4,200 of interest deducts all $4,200. Above $100,000 of MAGI (single, head of household, and married filing separately — MFS is not halved) or $200,000 (married filing jointly), the deduction drops $200 for each $1,000 of excess “or portion thereof”. That statutory phrase makes it a ceiling function: at $100,250 MAGI, a mere $250 of excess already costs the full $200, cutting a $5,000 interest bill's deduction to $4,800. At exactly $149,000 MAGI, 49 steps leave just $200 of a $10,000 interest bill deductible — and one dollar more of MAGI zeroes it. The correct elimination points are therefore MAGI above $149,000 / $249,000, not the $150,000/$250,000 many sites round to. A married couple at $230,000 MAGI with $6,000 of interest gets $0. All figures here are computed at build time by the same tested engine as the calculator above.

Two more mechanics: interest is capped at $10,000 before the reduction is applied, and the phase-out runs on MAGI — for most people that equals AGI; the MAGI Calculator covers the add-backs (IRC §§911, 931, 933 exclusions).

Where it goes on your return — and when it disappears

This deduction is claimed on Schedule 1-A and flows to Form 1040 line 13b: it is subtracted after AGI, so it is available whether or not you itemize, but it never reduces your AGI or MAGI — and therefore never helps you under any MAGI-based phase-out, including its own. It is temporary: tax years 2025 through 2028, then gone. Your lender reports the interest to the IRS on information returns once it reaches $600 (with transition relief for 2025 per IRS guidance), and reporting the VIN on your return is itself one of the seven statutory conditions. If you itemize, the other headline OBBBA change is the SALT cap — sized by the SALT Deduction Cap Calculator.

Frequently asked questions

Is car loan interest tax deductible in 2026?

It can be — for tax years 2025 through 2028 only, up to $10,000 of interest per year on a qualifying loan. All seven statutory requirements must be met: a new vehicle (original use starts with you), personal use, a qualifying vehicle type, final assembly in the United States, a first-lien purchase loan originated after December 31, 2024, none of the exclusions (leases, commercial use, related-party loans), and the VIN reported on your return. The deduction is claimed on Schedule 1-A (Form 1040 line 13b), so you get it whether or not you itemize — but it never reduces your AGI or MAGI.

Does a used car, a lease, or a refinance qualify?

Used vehicles never qualify — original use must start with the taxpayer. Lease payments never qualify either; the statute covers loan interest, not leases. A refinance can qualify: interest on the refinanced amount counts up to the original refinanced principal, as long as the new loan is still secured by a first lien on the vehicle.

How do I know if my car was finally assembled in the U.S.?

Check your VIN or window sticker — the statute requires U.S. final assembly, and the brand name alone tells you nothing (many "foreign" brands assemble in the U.S. and many "American" models do not). The VIN plant-of-manufacture character (49 CFR 565) or the vehicle information label (49 CFR 583.5(a)(3)) is the evidence; the NHTSA VIN Decoder at nhtsa.gov/vin-decoder reads it for you.

How does the income phase-out work?

As a staircase, not a slope: the deduction drops $200 for each $1,000 of MAGI over $100,000 (single, head of household, and married filing separately) or $200,000 (married filing jointly) — and a partial $1,000 counts as a full one, so one dollar of excess income costs a full $200. Because of that rounding rule the deduction hits $0 for MAGI above $149,000 / $249,000 — not the $150,000/$250,000 endpoints many sites publish.

Not tax advice: an educational estimate of the federal car-loan-interest deduction only (tax year 2026, returns filed 2027) — no state tax, AMT, or NIIT modeling. Eligibility follows IRC §163(h)(4) and the proposed regulations (Fed. Reg. 2026-01-02, doc 2025-24154); final IRS guidance may refine the details.
