If your business services, holds, or receives interest on consumer auto loans, a new federal information reporting requirement is now on the horizon. The IRS and Treasury have finalized rules that create a dedicated car loan interest reporting regime for certain passenger vehicle loans, with a key trigger: $600 or more of interest received from an individual during a calendar year.
On September 8, 2026, the IRS and Treasury published final regulations titled Car Loan Interest Deduction in the Federal Register as TD 10054, 91 FR 57214-57244. The final regulations are effective November 9, 2026 and implement changes made by Public Law 119-21, commonly known as the One, Big, Beautiful Bill Act, specifically OBBBA section 70203. You can review the government source text for the full rule.
The New Car Loan Interest Reporting Rule for 2026
What happened
OBBBA section 70203 added a temporary individual deduction for qualified passenger vehicle loan interest under IRC §163(h)(4) and created a new information reporting requirement under IRC §6050AA. It also amended IRC §63(b) so eligible taxpayers who do not itemize can still benefit from the deduction, and amended IRC §6724(d) so the new returns and borrower statements fall within the penalty framework for information returns and payee statements.
The central reporting change is straightforward but operationally significant: any person engaged in a trade or business that receives from any individual interest aggregating $600 or more for a calendar year on a specified passenger vehicle loan must file an information return with the IRS and furnish a written statement to the borrower.
Why it matters for 1099-style information reporting
Before OBBBA section 70203(c), there was no IRC §6050AA car loan interest reporting regime. After the new rule applies, the threshold is $600 or more of interest per calendar year from an individual on a specified passenger vehicle loan.
That makes this a new reporting category that tax, compliance, loan servicing, and IT teams should start mapping now. It may not be a traditional Form 1099 filing rule, but it has familiar information reporting features: a federal return, a borrower statement, e-filing considerations, and penalties for late or incorrect reporting.
What Does This Mean for 1099 Filers?
A new information reporting category, not a traditional 1099-NEC or 1099-MISC rule
For businesses accustomed to filing 1099 forms, the structure of this rule will feel familiar. However, the source regulation does not identify an existing form number such as Form 1099-NEC, Form 1099-MISC, Form 1099-INT, or Form 1098.
Instead, IRC §6050AA(b) states that the information return must be made “in the form prescribed by the Secretary.” That means lenders and finance businesses should watch for future IRS forms, instructions, publications, or e-file schemas that specify exactly how §6050AA reporting will be submitted.
Borrower statements are also required
The rule is not limited to IRS filing. Under IRC §6050AA(c), every person required to file the information return must also furnish a written statement to the individual borrower whose name is required to be included on the return.
That statement must show the interest recipient’s name, address, and phone number, plus the reportable loan, interest, and vehicle information required under IRC §6050AA(b)(2)(B) through (F).
E-filing may apply under the 10-return rule
The final regulations also address electronic filing under IRC §6011. Under IRC §6011(e)(5), Treasury may require electronic filing if the taxpayer is required to file at least 10 returns of any type during a calendar year.
That “any type” language matters. A lender that files W-2s, 1099s, ACA forms, and now §6050AA information returns may need to aggregate return counts when evaluating e-filing requirements. If your business is already familiar with e-filing information returns, this should become part of the same compliance planning conversation.
What Changed
The $600 reporting threshold
IRC §6050AA(a) applies when a person engaged in a trade or business receives from any individual interest aggregating $600 or more for any calendar year on a specified passenger vehicle loan.
The before-and-after change is important:
- Before OBBBA section 70203(c): There was no dedicated IRC §6050AA car loan interest reporting regime.
- After the new rule applies: A business that receives $600 or more of covered interest from an individual during a calendar year must file an information return and furnish a borrower statement.
What must be reported to the IRS
Under IRC §6050AA(b), the information return must include several specific data fields. Businesses should not wait until the IRS releases the prescribed form to begin checking whether these fields are consistently captured in loan systems.
- Name and address of the individual from whom the interest was received.
- Amount of interest received for the calendar year.
- Outstanding principal on the specified passenger vehicle loan as of the beginning of the calendar year.
- Date of origination of the loan.
- Year, make, model, and vehicle identification number (VIN) of the applicable passenger vehicle securing the loan, or another vehicle description prescribed by the IRS.
- Any other information the IRS may prescribe.
What must be furnished to borrowers
The borrower statement under IRC §6050AA(c) must show the interest recipient’s name, address, and phone number. It must also include the reportable information required under §6050AA(b)(2)(B) through (F), which includes the interest amount, principal balance, origination date, vehicle information, and any additional IRS-required information.
For borrowers, that statement may become an important tax document because the reporting rule is tied to the temporary deduction for qualified passenger vehicle loan interest.
How the vehicle loan must qualify
A specified passenger vehicle loan generally refers to indebtedness described in IRC §163(h)(4)(B) with respect to an applicable passenger vehicle. The indebtedness must be incurred after December 31, 2024, must be for the purchase of an applicable passenger vehicle, must be secured by a first lien, and must relate to a vehicle for personal use.
The applicable passenger vehicle rules under IRC §163(h)(4)(D) include several vehicle requirements. The final regulations emphasize that final assembly must have occurred within the United States and that the vehicle must have a gross vehicle weight rating of less than 14,000 pounds.
The final regulations also clarify that “secured by a first lien” generally means the first voluntary security interest recorded against the vehicle, disregarding involuntary liens that may later receive temporary higher priority. They also address practical situations such as lien perfection delays under state law and limited cases where a lien is removed after repossession or an insurance payout following a total loss claim.
Connection to the borrower’s car loan interest deduction
The reporting rule exists because Congress created a temporary deduction for qualified passenger vehicle loan interest. Under IRC §163(h)(4), certain taxpayers may deduct up to $10,000 of qualified passenger vehicle loan interest for taxable years beginning after December 31, 2024, and before January 1, 2029.
IRC §6050AA(f) links the reporting requirement to that deduction period by providing that no information return is required under §6050AA for any period to which §163(h)(4) does not apply.
Timeline and Deadlines
Statutory and regulatory milestones
The final rule did not appear out of nowhere. It followed a statutory change, transitional guidance, proposed regulations, a public hearing, and final regulations.
2025 transition relief
The source text notes that Notice 2025-57 provides transitional guidance for interest received in calendar year 2025. Under that notice, an interest recipient is deemed to satisfy §6050AA reporting obligations for interest on specified passenger vehicle loans received in calendar year 2025 if it makes a statement available to the individual showing the total amount of interest received in 2025 on the loan.
2026 effective date and beyond
The final regulations are effective November 9, 2026. The underlying deduction applies for taxable years beginning after December 31, 2024, and before January 1, 2029, so businesses should monitor IRS guidance for calendar-year reporting obligations that fall within that window.
As with other information reporting processes, deadlines can become a major compliance risk once a form is prescribed. Businesses should continue tracking IRS updates and broader filing deadlines as the §6050AA process becomes clearer.
Who Is Affected
Businesses that receive qualifying interest
The rule affects any person engaged in a trade or business that receives $600 or more of interest from an individual in a calendar year on a specified passenger vehicle loan. Potentially affected organizations may include banks, credit unions, auto finance companies, captive finance companies, vehicle dealers that hold or receive interest on qualifying installment contracts, and other businesses that receive covered vehicle loan interest.
This is not a blanket rule for every commercial loan. It applies to interest received from individuals on covered passenger vehicle loans that meet the statutory requirements.
Borrowers who may need the statement for tax filing
Borrowers are affected because the furnished statement may help them determine how much qualified passenger vehicle loan interest they may be able to deduct. The deduction is limited to up to $10,000 and applies only for the temporary period set by IRC §163(h)(4).
Businesses that may cross the e-filing threshold
Entities that file at least 10 returns of any type during a calendar year should evaluate whether IRC §6011(e) electronic filing rules apply to their §6050AA returns. This matters especially for organizations already filing W-2s, ACA forms, or information returns such as Form 1099-NEC and Form 1099-MISC.
The penalty framework also applies because OBBBA section 70203(c)(2) amended IRC §6724(d)(1) to include §6050AA returns in the definition of “information return” and amended IRC §6724(d)(2) to include §6050AA statements in the definition of “payee statement.”
How to Prepare
Identify reportable loans and borrowers
Start by reviewing your vehicle loan portfolio to identify loans that may be specified passenger vehicle loans under IRC §§6050AA and 163(h)(4). Focus on loans incurred after December 31, 2024, secured by a first lien, tied to applicable passenger vehicles, and used for personal purposes.
Your systems should be able to track when an individual borrower’s annual interest payments reach or exceed the $600 reporting threshold for a calendar year.
Capture the required data fields
The required data fields go beyond the borrower’s name and annual interest amount. You will need reliable access to loan and vehicle data, including the beginning-of-year outstanding principal, origination date, and vehicle year, make, model, and VIN.
Also confirm that your systems can distinguish interest from other amounts and fees. The final regulations discuss items such as prepaid interest, points, deferred or capitalized interest, origination-related or financing-related charges, prepayment penalties, late payment charges, and default-related charges when they are treated as interest for federal income tax purposes.
Plan for borrower statement delivery
Borrower statements should be built into your customer communication workflow, not treated as an afterthought. The statement must include the interest recipient’s contact information and the required loan, interest, and vehicle data.
Because borrowers may use the statement for tax filing, accuracy and clarity will matter. Businesses should also monitor whether the IRS prescribes specific furnishing deadlines, formatting requirements, or electronic delivery rules.
Prepare for e-filing and penalty prevention
Evaluate whether your business files 10 or more returns of any type during the calendar year. If so, mandatory e-filing under IRC §6011(e)(5) may be relevant once the IRS prescribes the §6050AA filing mechanism.
Build review procedures now to reduce penalty exposure. IRC §6721 penalties may apply for failure to file correct information returns, and IRC §6722 penalties may apply for failure to furnish correct payee statements. If mistakes happen, having a correction process in place is important; businesses can learn more about information return corrections before filing season pressure hits.
FAQ
What is car loan interest reporting under IRC §6050AA?

Yes. The reporting threshold is interest aggregating $600 or more from an individual for a calendar year on a specified passenger vehicle loan.
Does the source document name a specific 1099 form?
No. The final regulations state that the information return must be in the form prescribed by the Secretary. The source document does not name a specific Form 1099-NEC, Form 1099-MISC, Form 1099-INT, Form 1098, or other final form number for §6050AA reporting.
When do the final regulations become effective?
The final regulations are effective November 9, 2026.
What penalties can apply?
Penalties may apply under IRC §6721 for failure to file correct information returns and under IRC §6722 for failure to furnish correct payee statements. Because §6050AA returns and statements were added to the definitions in IRC §6724(d), lenders should treat this as a penalty-sensitive reporting process.
Start Preparing for §6050AA Car Loan Interest Reporting
The final regulations create a concrete new obligation for businesses that receive $600 or more of interest from an individual on a specified passenger vehicle loan.
