Here’s what HIVE AI had to say about “What are the new rules for deducting auto loan interest, and who qualifies under the One Big Beautiful Bill?”:

Auto Loan Interest Deduction Under the One Big Beautiful Bill

The One Big Beautiful Bill introduces a significant new tax benefit that allows taxpayers to deduct interest paid on qualifying auto loans for personal use vehicles. This provision represents a departure from the longstanding rule that personal interest, including auto loan interest, is generally not deductible for individual taxpayers.

Qualified Passenger Vehicle Loan Interest Definition and Scope

In the case of taxable years beginning after December 31, 2024, and before January 1, 2029, for purposes of this subsection the term ‘personal interest’ shall not include qualified passenger vehicle loan interest. For purposes of this paragraph, the term ‘qualified passenger vehicle loan interest’ means any interest which is paid or accrued during the taxable year on indebtedness incurred by the taxpayer after December 31, 2024, for the purchase of, and that is secured by a first lien on, an applicable passenger vehicle for personal use. One Big Beautiful Bill Act: Sec. 70203. No tax on car loan interest

The legislation creates a temporary exception to the general rule that personal interest is not deductible. Under current law, if you are an employee, you can’t deduct any interest paid on a car loan. This interest is treated as personal interest and isn’t deductible. IRS – Publication 463: Travel, Gift, and Car Expenses The One Big Beautiful Bill changes this fundamental principle for qualifying auto loans during the specified period.

The deduction applies specifically to interest on loans used to purchase vehicles for personal use, distinguishing it from business vehicle interest which has always been deductible under different provisions. You cannot deduct on Schedule C the interest you paid on personal loans. If a loan is part business and part personal, you must divide the interest between the personal part and the business part. IRS – Publication 334: Tax Guide for Small Business (For Individuals Who Use Schedule C) The new provision creates a separate category for personal vehicle loan interest that becomes deductible regardless of business use.

Vehicle Qualification Requirements and Restrictions

The term ‘applicable passenger vehicle’ means any vehicle— (i) the original use of which commences with the taxpayer, (ii) which is manufactured primarily for use on public streets, roads, and highways (not including a vehicle operated exclusively on a rail or rails), (iii) which has at least 2 wheels, (iv) which is a car, minivan, van, sport utility vehicle, pickup truck, or motorcycle, (v) which is treated as a motor vehicle for purposes of title II of the Clean Air Act, and (vi) which has a gross vehicle weight rating of less than 14,000 pounds. One Big Beautiful Bill Act: Sec. 70203. No tax on car loan interest

The vehicle must be new to the taxpayer, meaning the original use must commence with the taxpayer claiming the deduction. This requirement ensures that the benefit applies only to new vehicle purchases rather than used vehicle transactions. The legislation also includes specific vehicle type requirements, covering most common passenger vehicles while excluding commercial trucks and other heavy vehicles.

An important domestic manufacturing requirement applies to qualifying vehicles. Such term shall not include any vehicle the final assembly of which did not occur within the United States. One Big Beautiful Bill Act: Sec. 70203. No tax on car loan interest This provision ensures that the tax benefit supports domestic automotive manufacturing and assembly operations.

The legislation provides a detailed definition of final assembly to prevent circumvention of the domestic requirement. For purposes of subparagraph (D), the term ‘final assembly’ means the process by which a manufacturer produces a vehicle at, or through the use of, a plant, factory, or other place from which the vehicle is delivered to a dealer with all component parts necessary for the mechanical operation of the vehicle included with the vehicle, whether or not the component parts are permanently installed in or on the vehicle. One Big Beautiful Bill Act: Sec. 70203. No tax on car loan interest

Loan Structure and Security Requirements

The qualifying loan must meet specific structural requirements to ensure the deduction applies only to legitimate vehicle financing arrangements. The indebtedness must be secured by a first lien on the applicable passenger vehicle, creating a direct connection between the loan and the vehicle purchase. This requirement prevents taxpayers from claiming the deduction for unsecured personal loans that might be used to purchase vehicles.

Indebtedness described in subparagraph (B) shall include indebtedness that results from refinancing any indebtedness described in such subparagraph, and that is secured by a first lien on the applicable passenger vehicle with respect to which the refinanced indebtedness was incurred, but only to the extent the amount of such resulting indebtedness does not exceed the amount of such refinanced indebtedness. One Big Beautiful Bill Act: Sec. 70203. No tax on car loan interest This provision allows taxpayers to maintain the deduction benefit when refinancing qualifying auto loans, provided the refinanced amount does not exceed the original loan balance.

The legislation includes anti-abuse provisions to prevent manipulation through related party transactions. Indebtedness described in subparagraph (B) shall not include any indebtedness owed to a person who is related (within the meaning of section 267(b) or 707(b)(1)) to the taxpayer. One Big Beautiful Bill Act: Sec. 70203. No tax on car loan interest This restriction ensures that the deduction applies only to arm’s length financing arrangements with unrelated lenders.

Excluded Loan Types and Commercial Restrictions

The legislation includes comprehensive exclusions to ensure the deduction applies only to appropriate personal vehicle financing. Such term shall not include any amount paid or incurred on any of the following: (I) A loan to finance fleet sales. (II) A loan incurred for the purchase of a commercial vehicle that is not used for personal purposes. (III) Any lease financing. (IV) A loan to finance the purchase of a vehicle with a salvage title. (V) A loan to finance the purchase of a vehicle intended to be used for scrap or parts. One Big Beautiful Bill Act: Sec. 70203. No tax on car loan interest

These exclusions prevent the deduction from applying to commercial vehicle transactions, fleet purchases, and vehicles that are not intended for normal personal transportation use. The exclusion of lease financing ensures that the benefit applies only to ownership transactions rather than rental or lease arrangements.

Annual Dollar Limitations and Income-Based Phase-Outs

The amount of interest taken into account by a taxpayer under subparagraph (B) for any taxable year shall not exceed $10,000. One Big Beautiful Bill Act: Sec. 70203. No tax on car loan interest This annual cap ensures that the deduction provides meaningful benefits for typical auto loan interest while preventing excessive tax benefits for high-end vehicle purchases or multiple vehicle transactions.

The legislation includes a comprehensive income-based phase-out mechanism to target the benefit toward middle and lower-income taxpayers. The amount which is otherwise allowable as a deduction under subsection (a) as qualified passenger vehicle loan interest (determined without regard to this clause and after the application of clause (i)) shall be reduced (but not below zero) by $200 for each $1,000 (or portion thereof) by which the modified adjusted gross income of the taxpayer for the taxable year exceeds $100,000 ($200,000 in the case of a joint return). One Big Beautiful Bill Act: Sec. 70203. No tax on car loan interest

This phase-out structure creates a 20% reduction rate, meaning that for every $1,000 of income above the threshold, the deduction is reduced by $200. The phase-out completely eliminates the deduction when modified adjusted gross income reaches $150,000 for single filers and $300,000 for joint filers.

For purposes of this clause, the term ‘modified adjusted gross income’ means the adjusted gross income of the taxpayer for the taxable year increased by any amount excluded from gross income under section 911, 931, or 933. One Big Beautiful Bill Act: Sec. 70203. No tax on car loan interest This comprehensive definition prevents taxpayers from avoiding the phase-out limitations through the use of foreign earned income exclusions or similar provisions.

Vehicle Identification and Compliance Requirements

Interest shall not be treated as qualified passenger vehicle loan interest under this paragraph unless the taxpayer includes the vehicle identification number of the applicable passenger vehicle described in clause (i) on the return of tax for the taxable year. One Big Beautiful Bill Act: Sec. 70203. No tax on car loan interest This requirement ensures proper identification of qualifying vehicles and enables the IRS to verify that claimed deductions relate to eligible vehicles.

The VIN requirement serves multiple compliance purposes, including preventing duplicate claims for the same vehicle and enabling cross-referencing with manufacturer and dealer records to verify domestic assembly requirements. This administrative provision helps maintain the integrity of the deduction while providing the IRS with necessary information for enforcement.

Above-the-Line Deduction Treatment

Section 63(b), as amended by the preceding provisions of this Act, is amended by striking “and” at the end of paragraph (5), by striking the period at the end of paragraph (6) and inserting “and”, and by adding at the end the following new paragraph: “(7) so much of the deduction allowed by section 163(a) as is attributable to the exception under section 163(h)(4)(A).” One Big Beautiful Bill Act: Sec. 70203. No tax on car loan interest

This provision ensures that the auto loan interest deduction is available to all qualifying taxpayers regardless of whether they choose to itemize other deductions. The above-the-line treatment makes the deduction more valuable than itemized deductions because it reduces adjusted gross income, which can affect the calculation of other tax benefits and phase-outs.

Comprehensive Reporting Requirements for Lenders

The legislation establishes detailed reporting requirements for financial institutions and other lenders who receive qualifying auto loan interest payments. Any person— (1) who is engaged in a trade or business, and (2) who, in the course of such trade or business, receives from any individual interest aggregating $600 or more for any calendar year on a specified passenger vehicle loan, shall make the return described in subsection (b) with respect to each individual from whom such interest was received at such time as the Secretary may provide. One Big Beautiful Bill Act: Sec. 70203. No tax on car loan interest

A return is described in this subsection if such return— (1) is in such form as the Secretary may prescribe, and (2) contains— (A) the name and address of the individual from whom the interest described in subsection (a)(2) was received, (B) the amount of such interest received for the calendar year, (C) the amount of outstanding principal on the specified passenger vehicle loan as of the beginning of such calendar year, (D) the date of the origination of such loan, (E) the year, make, model, and vehicle identification number of the applicable passenger vehicle which secures such loan (or such other description of such vehicle as the Secretary may prescribe), and (F) such other information as the Secretary may prescribe. One Big Beautiful Bill Act: Sec. 70203. No tax on car loan interest

These reporting requirements enable the IRS to match taxpayer deduction claims with lender reports, ensuring compliance and preventing fraudulent claims. The detailed vehicle information requirements support verification of domestic assembly and other qualification criteria.

Taxpayer Statement Requirements

Every person required to make a return under subsection (a) shall furnish to each individual whose name is required to be set forth in such return a written statement showing— (1) the name, address, and phone number of the information contact of the person required to make such return, and (2) the information described in subparagraphs (B), (C), (D), and (E) of subsection (b)(2) with respect to such individual (and such information as is described in subsection (b)(2)(F) with respect to such individual as the Secretary may provide for purposes of this subsection). One Big Beautiful Bill Act: Sec. 70203. No tax on car loan interest

This requirement ensures that taxpayers receive the information necessary to properly claim the deduction on their tax returns. The statement requirement creates a paper trail that supports both taxpayer compliance and IRS verification efforts.

Temporary Nature and Sunset Provisions

The auto loan interest deduction is explicitly temporary, applying only to taxable years 2025 through 2028. In the case of taxable years beginning after December 31, 2024, and before January 1, 2029, for purposes of this subsection the term ‘personal interest’ shall not include qualified passenger vehicle loan interest. One Big Beautiful Bill Act: Sec. 70203. No tax on car loan interest This four-year window provides meaningful relief while creating a defined period for evaluating the provision’s effectiveness.

The temporary nature requires future legislative action for extension, allowing policymakers to assess the economic impact and policy effectiveness before making permanent changes to the personal interest deduction rules. The sunset provision also helps manage the revenue impact of the legislation by limiting the duration of the tax benefit.

Coordination with Existing Interest Deduction Rules

The new auto loan interest deduction operates within the existing framework of Section 163, which governs interest deductions generally. Section 163 generally allows a deduction for any interest paid or accrued on indebtedness in the taxable year. Section 163(h)(1) provides an exception to this general rule of deductibility for “personal interest”. Section 163(h)(2) defines personal interest to mean “any interest allowable as a deduction” other than, as relevant here, interest paid or accrued on indebtedness properly allocable to a trade or business, or investment interest (as defined in section 163(d)), or “qualified residence interest” (as defined in section 163(h)(3)). Dawson U.S. Tax Court Opinions: Clifton E. Stanley & Darlene H. Stanley

The One Big Beautiful Bill creates a new exception to the personal interest limitation specifically for qualifying auto loan interest, joining the existing exceptions for business interest, investment interest, and qualified residence interest. This approach maintains the overall structure of interest deduction rules while creating a targeted benefit for personal vehicle financing.

Economic Impact and Policy Rationale

The auto loan interest deduction represents a significant policy shift that recognizes the essential nature of personal transportation in modern American life. By making auto loan interest deductible, the legislation acknowledges that vehicle ownership is often necessary for employment, education, and other essential activities, distinguishing it from other forms of personal consumption.

The income-based phase-out mechanism ensures that the benefit is concentrated among middle and lower-income taxpayers who are most likely to need financing for vehicle purchases and for whom the interest deduction provides the greatest relative benefit. The domestic assembly requirement supports American manufacturing while the temporary nature allows for policy evaluation and adjustment.

The comprehensive reporting requirements and compliance provisions demonstrate a careful balance between providing meaningful tax relief and maintaining system integrity. The detailed vehicle identification and lender reporting requirements enable effective administration while preventing abuse of the deduction.

Auto Loan Interest Deduction Phase-Out (2025)

Under the One Big Beautiful Bill Act (OBBBA), certain taxpayers can deduct interest on qualifying auto loans, but the benefit phases out at higher incomes.

Phase-out rules for 2025:

  • Deduction limit: Up to $10,000 of interest per year for loans on U.S.-assembled vehicles.
  • Single filers: Deduction phases out between $100,000–$120,000 of modified adjusted gross income (MAGI).
  • Married filing jointly: Phases out between $200,000–$240,000 MAGI.
  • No deduction is available above the upper limit.
  • Applies only to loans originated between Jan. 1, 2025, and Dec. 31, 2028.

How Much of Your Car Loan Interest Is Tax Deductible?

For 2025, you can deduct 100% of the interest you paid on a qualifying auto loan, up to the $10,000 annual cap, as long as:

  1. The vehicle is assembled in the United States.
  2. You meet the income requirements before phase-out.
  3. The loan is used solely to purchase that vehicle.

Do You Have to Pay Taxes on Stuff You Sell on eBay?

Yes. In 2025, money you earn from selling items on eBay may be taxable, depending on what you sold and whether you made a profit.

  • Personal items sold at a loss (e.g., selling your used phone for less than you paid) are not taxable.
  • Items sold for more than you paid create a taxable gain that must be reported as income.
  • If you sell frequently or run it like a business, your sales are treated as self-employment income and are fully taxable.
  • eBay and other payment processors must send you Form 1099-K if your total payments exceed $5,000 in a calendar year (OBBBA 2025 rule).
