2025 Tax Season: What Dealers Should Know
6 Tax Updates Auto Dealers Can’t Ignore in 2025
By Aidan Martin, CPA & Jake Gentile, CPA
The 2025 tax season is almost here, and with it comes a host of changes that auto dealerships can’t afford to overlook. From shifting tax rules to fresh opportunities with credits and deductions, being proactive is the key to success.
Below, we break down everything you need to know to keep your dealership ahead of the curve.

1. Section 163(j) Limitation Changes: A New Math Problem for Interest Deductions
Let’s talk numbers. The calculation for the Section 163(j) interest deduction can be tricky:
Goodbye, EBITDA. Hello, EBIT
The interest deduction limit is now based on 30% of EBIT (Earnings Before Interest and Taxes), not EBITDA (which includes depreciation and amortization). That means fewer deductions for businesses with high depreciation costs—like auto dealerships.
The Bright Side: Floor Plan Interest Stays Fully Deductible
If you’re using floor plan financing to stock your inventory, this interest remains 100% deductible. To maximize your benefits, review your financing structure and consider reallocating debt to make the most of this exclusion.
2. Bonus Depreciation Phase-Down: Timing Is Everything
The window to take advantage of bonus depreciation is closing…fast. This coming tax season (for the 2024 tax year) the rate dropped to 60% for qualified property. This includes dealership upgrades, machinery, and fleet vehicles.
Pro Tip
If you’re planning big investments, act now. The depreciation is set to decrease over the next two years. Lock in purchases before year-end to capture the higher depreciation rate. Not ready? No worries, Section 179 expensing might still have your back.
3. Commercial Clean Vehicle Credit (Section 45W): Bigger Incentives for Going Green
Thinking about adding EVs to your fleet? The Section 45W credit is here to help.
- For Heavyweights: If your fleet includes vehicles over 14,000 lbs, you can snag a credit of up to $40,000 per vehicle.
- For Lighter Rides: Lighter EVs (under 14,000 lbs) still qualify for $7,500.
- Charging Up: Install EV charging stations to support your fleet, and you’ll get an additional tax credit for the infrastructure. It’s a win-win for your bottom line and sustainability goals.
4. Alternative Fuel Refueling Property Credit (Section 30C): Doubling Down on EV Infrastructure
With more customers and businesses moving toward EVs, dealerships investing in charging stations stand to benefit in a big way. Updates to Section 30C sweeten the deal:
- Higher Credit Caps: In low-income or rural areas, you can now claim 50% of installation costs, up to $200,000 per station (that’s double the previous limit).
- More Locations Qualify: New, more flexible criteria mean more dealerships can tap into this expanded credit.
5. Ohio’s Commercial Activity Tax (CAT): A Break for Smaller Dealerships
Good news for Ohio auto dealerships: CAT updates mean fewer businesses will be subject to the tax.
- The New Threshold: If your taxable gross receipts are $6 million or less, you’re off the hook. You can even cancel your CAT account effective December 31, 2024. For quarterly taxpayers, this could mean immediate savings.
6. Corporate Transparency Act (CTA): BOI Reporting on Hold (For Now)
Here’s a twist: the Corporate Transparency Act (CTA) BOI reporting requirements are on pause again, thanks to a nationwide injunction.
- What You Should Know: “Reporting Companies” are not required to file BOI reports at this time, though voluntary submissions are still being accepted by FinCEN. Stay tuned for updates—this one’s not over yet.
Wrapping It Up: Don’t Let the 2025 Tax Season Sneak Up on You
Taxes can feel like a lot — especially with all these changes — but a little planning goes a long way. From optimizing your financing under Section 163(j) to cashing in on EV credits and bonus depreciation, there are plenty of ways to stay ahead.
