Overview of New Reporting Rules in 2025

The One, Big, Beautiful Bill introduces fresh information return requirements for lenders reporting car loan interest, and for platforms issuing Form 1099-K. Additional transitional reliefs have been issued.(irs.gov)

Car Loan Interest Reporting & Deductibility

  • For interest received in 2025 from qualified passenger vehicle loans, lenders must report interest of $600 or more via new returns or borrower statements. A “qualified passenger vehicle” includes most cars, SUVs, pickups etc., with final assembly in the U.S. and under 14,000 lbs.(irs.gov)
  • Businesses receive transition relief: no penalties if they meet reporting by making the amount of interest received available via, e.g., online portals, monthly, or annual statements.(irs.gov)

1099-K Form Threshold Reversion

  • Under OBBB, the gross payments threshold for TPSOs to issue 1099-K goes back to $20,000 plus more than 200 transactions.(irs.gov)
  • ARPA had lowered it to $600 regardless of transaction count. Now the old threshold returns.(irs.gov)

Compliance Timeline & Requirements

RuleEffectiveWhat to Do Now
Car Loan Interest Reporting – Official reporting/penalty reliefAlready effective for 2025Lenders should prepare portal/statements, ensure statements to borrowers, track thresholds; maintain documentation to avoid penalties.(irs.gov)
1099-K Reporting ThresholdAlready revertedPlatforms (e.g., payment apps) should revert to the higher threshold; communicate to users; individuals should monitor whether they receive 1099-K and keep records of transactions and income.(irs.gov)

Practical Examples

  • Auto dealer or lender: If you sell or finance passenger vehicles and collect interest >= $600 in 2025, you must report. If you issue an annual statement or allow secure portal access, you're compliant and safe from penalties.
  • Gig workers / small sellers: If you sell goods/services over third-party platforms and expect payments approaching $20,000 and 200+ transactions, expect to receive Form 1099-K. If you're far below both thresholds, you likely won’t—but all income remains taxable regardless.

Tips to Avoid Pitfalls

  • Keep detailed transaction records (dates, amounts, payment processors) — especially if operating on multiple platforms.
  • Ensure borrowers receive statements that clearly show total interest, satisfying the car loan reporting requirement.
  • Monitor IRS Fact Sheets and guidance—these rules can involve further clarifications and safe harbors.

Takeaway: New reporting requirements under OBBB bring changes, but the IRS is offering relief and transitional mechanisms. Understanding thresholds, proper reporting tools, and documentation now goes a long way toward compliance and avoiding surprises later.
