Key Tax Benefits When You Lease:
- Deduct the business-use percentage of your monthly lease payments

- Lease inclusion rule may slightly reduce deductions if vehicle value is ~$60K+
👌 Real Example: Leasing Tony, a business consultant, leases a car for $600/month and uses it 90% for business.
- Deduction = $600 × 12 × 90% = $6,480/year
- No bonus depreciation applies to leases

Q: Can I lease now and buy later?
A: Yes, but the tax treatment may change. Talk to your CPA first.

A: Both are allowed.
- Mileage = simpler

Q: Can I deduct a financed vehicle?
A: Yes — as long as you’re the owner and the vehicle is used for business. The deduction is based on use and purchase price, not the payment schedule.
