What is the new IRS car loan interest deducti and who qualifies?

It is a proposed temporary deduction of up to $10,000 on interest paid for loans on new vehicles assembled in the United States during 2025–2028. Borrowers must have qualifying loan statements and VIN documentation. It reduces taxable income by the interest amount, subject to IRS rules, income limits, and proper reporting by lenders.

How could the deduction affect Tesla’s sales and pricing?

Lower after-tax borrowing costs can widen affordability, supporting orders for U.S.-built Tesla models. If lenders implement reporting quickly, adoption could be broader in 2025. That may help Tesla hold prices with fewer discounts, aiding margins. Effects depend on APR levels, buyer income, and how the deduction interacts with other incentives.

What should UK investors watch as the rules roll out?

Focus on U.S. order trends, delivery mix, and management commentary in 2026 guidance. Track lender compliance with VIN and interest reporting, which will drive adoption. Watch valuation metrics like P/E and price-to-sales, FX exposure to USD, and technical signals around support and momentum before adjusting positions.

When is Tesla’s next earnings report and what matters most?

Tesla reports on 28 January 2026 at 21:00 UTC. We will monitor commentary on U.S. order intake tied to the deduction, financing mix, inventory, pricing discipline, and margin trajectory. Updates on 2026 deliveries, capex, and new model timing will also shape expectations and volatility around the print.

Can the deduction be combined with other EV incentives?

The proposed rules target loan interest, not vehicle price, so it may stack with other federal or state incentives where permitted. Buyers must confirm their eligibility and ensure lender statements include VIN and interest totals. Always check current IRS guidance and state programmes before assuming combined benefits.
