Can I Deduct My Car Payment? A Self-Employed Guide

Short answer: no, you can’t deduct the car payment itself. But you can deduct most of what’s inside the payment — and a new federal deduction under OBBBA (P.L. 119-21) finally lets you deduct up to $10,000/year of personal car loan interest through 2028.

Key takeaways

• The monthly car payment itself (principal + interest) is never a direct deduction.
• The business use of the car is what’s deductible — via the standard mileage rate or actual expenses.
• Self-employed drivers using actual expenses deduct the business-use share of loan interest on Schedule C, Line 16b.
• A new deduction under OBBBA §70203 / IRC §163(h)(4) lets you deduct up to $10,000/year of interest on a personal car loan for tax years 2025–2028 — separate from any business deduction.

Is my car payment tax deductible?

Not directly. Your loan payment has two parts: principal (paying back the money you borrowed) and interest (paying for the right to borrow it). Principal is never directly deductible — it’s just basis you’ll recover later through depreciation or by reducing gain when you sell. Interest is potentially deductible, but whether it actually is depends on who you are, what you’re using the car for, and which method you pick.

For a self-employed driver, the deduction flows through one of two methods: the standard mileage rate or the actual expense method. You pick one per vehicle per tax year, and there are rules about switching.

Method 1: The standard mileage rate

For 2026, the IRS standard mileage rate is 72.5¢ per business mile (IRS Notice 2026-10). That rate is a bundled per-mile allowance — it covers gas, oil, maintenance, tires, insurance, registration, and depreciation. The IRS spells out that 35¢ of the 72.5¢ is treated as depreciation for basis-reduction purposes.

If you use this method, you can’t separately deduct depreciation, gas, or repairs — they’re already in the rate. But you can still deduct on top:

• Business-related parking and tolls (per IRS Topic 510 and Pub 463)
• The business-use percentage of your car loan interest if you’re self-employed (Pub 463 confirms this; it’s often missed)
• State/local personal property tax on the vehicle (business-use share)

See our Standard Mileage vs Actual Expenses pillar for the side-by-side decision.

Method 2: The actual expense method

Track every expense, then deduct the business-use percentage. Eligible costs include gas, insurance, repairs, oil, tires, registration fees, lease payments, depreciation, and loan interest.

The interest piece is where the car payment comes back in. If you finance the vehicle and use it 80% for business, you deduct 80% of the loan interest on Schedule C, Line 16b (“Interest — other”). The other 20% is personal interest — historically nondeductible, but see §163(h)(4) below.

Depreciation is also capped. Under §280F, passenger autos placed in service in 2026 hit the “luxury auto” ceilings (per Rev. Proc. 2026-15): first-year depreciation is limited to $12,300 without bonus depreciation, or $20,300 with bonus. Heavier vehicles over 6,000 lbs GVWR escape those caps and can be eligible for §179 (see our Section 179 Heavy Vehicle pillar).

What’s the new OBBBA deduction for personal car loan interest?

This is the headline change. OBBBA §70203 added a new IRC §163(h)(4) creating a temporary deduction for qualified passenger vehicle loan interest (QPVLI). It’s claimed on the new Schedule 1-A, Part IV, which flows to Form 1040, Line 13b — and you get it whether you itemize or take the standard deduction.

To qualify, all of the following must be true:

• The loan was originated after December 31, 2024 and is secured by a first lien on the vehicle.
• The vehicle’s original use begins with you (no used vehicles).
• Final assembly in the United States (verify via the NHTSA VIN decoder).
• The vehicle is a car, van, SUV, pickup, or motorcycle under 14,000 lbs GVWR.
• You acquired it for personal use — measured by >50% expected personal use at the time of purchase (proposed reg §1.163-16, REG-113515-25, Fed. Reg. Jan. 2, 2026).
• Your MAGI is below the phaseout cap. The deduction is reduced $200 for each $1,000 of MAGI over $100,000 (single, HOH, MFS) or $200,000 (MFJ) — fully phased out at $150,000 / $250,000.

The deduction does not reduce SE tax — it’s an income-tax-only benefit.

The mixed-use trick

The proposed regs include a planning point that matters a lot for gig drivers. If your vehicle meets the personal-use test (>50% expected personal use at purchase), all the interest qualifies as QPVLI — you don’t have to allocate. But you can choose to deduct part as business interest on Schedule C instead, and the rest as QPVLI on Schedule 1-A. You just can’t deduct the same dollar twice.

Example 1 — Marcus the gig driver. New US-assembled SUV, financed, 75% personal / 25% rideshare. He uses the standard mileage rate, so he gets 72.5¢ × his business miles on Schedule C. He pays $2,000 of loan interest in 2026. Because his expected personal use was 75% (above 50%), the full $2,000 qualifies as QPVLI on Schedule 1-A. He can also elect to put $500 (the 25% business share) on Schedule C, Line 16b — but if he does, only $1,500 goes on Schedule 1-A.

Example 2 — Devon the contractor. New US-assembled F-150, 85% business / 15% personal, actual-expense method, §179 election year one. Because expected business use is >50%, the truck does not qualify as a “personal use” vehicle under §163(h)(4) — no QPVLI for Devon. He deducts 85% of loan interest on Schedule C, claims §179 and bonus depreciation on the business-use share of basis (the truck escapes the §280F luxury auto cap because GVWR > 6,000 lbs), and the 15% personal interest is simply nondeductible.

Can I deduct lease payments instead?

Leasing is different. Loan interest doesn’t exist on a lease — you’re paying for use, not buying the car. If you use the actual expense method, the business-use share of lease payments is deductible on Schedule C, Line 20a. Watch out for the §280F lease inclusion amount: for vehicles first leased in 2026 with a fair market value over $62,000 (per Rev. Proc. 2026-15, Table 3), you must add back a small income inclusion each year to neutralize the luxury-car benefit. QPVLI does not apply to leases — it’s a financed-purchase deduction only.

The biggest unforced error gig drivers make on a financed vehicle is treating it as one decision — “do I use standard mileage or actual expenses?” — when there are really three: the business-use deduction on Schedule C, the new QPVLI on Schedule 1-A, and the §280F basis math when you eventually sell. All three need the same input: an honest count of business miles vs. personal miles. Under Treas. Reg. §1.274-5T(c), the burden of proof is yours.

Frequently asked questions

Can I write off my entire car payment?

No. The car payment itself is not deductible. You deduct the business use of the car — either via the 2026 IRS standard mileage rate of 72.5¢/mile or via the actual expense method (business-use percentage of gas, insurance, repairs, depreciation, and loan interest). On top of that, post-2024 loans on a US-assembled personal-use vehicle may qualify for up to $10,000/year of QPVLI under IRC §163(h)(4).

Does the new OBBBA car loan interest deduction apply to a used Tesla?

No. Qualified passenger vehicle loan interest (QPVLI) under IRC §163(h)(4) requires that the vehicle's original use commence with you. Used vehicles are excluded, regardless of make or model.

What if I refinanced my 2024 car loan in 2025?

Refinancing of a pre-2025 loan generally does not bring it into QPVLI eligibility. The original indebtedness must be incurred after December 31, 2024.

Can married couples each get $10,000?

No — the $10,000 cap is per federal return. Married filing jointly couples get $10,000 total, not $20,000.

Does QPVLI reduce my self-employment tax?

No. QPVLI is an income-tax deduction only — claimed on Schedule 1-A, Part IV, flowing to Form 1040 Line 13b. It does not reduce the SE tax computed on Schedule SE.

Where does the standard mileage rate's depreciation component matter?

When you sell the car. The 35¢/mile depreciation component of the 2026 rate reduces your basis in the vehicle — meaning a larger taxable gain (or smaller loss) when you dispose of it. EveryLastMile keeps a year-by-year log so you can reconstruct accumulated depreciation at sale.
