The most tax-efficient way for a self-employed person to buy a car involves purchasing it in the business's name (if used over 50% for business), claiming accelerated depreciation (like Bonus Depreciation), deducting all actual expenses (gas, repairs, insurance, loan interest) or using the Standard Mileage Rate, and meticulously tracking business vs. personal use to maximize deductions and potentially build business credit while minimizing personal income tax.

How do self-employed people buy cars?

Is it smart to buy a car under an LLC?

Yes, buying a car under an LLC can be smart for business owners due to liability protection (shielding personal assets from accidents/lawsuits) and tax benefits (deducting expenses like interest, maintenance, gas).

A lease makes the most sense if it's important to you to drive a new car and replace it every two years or so. Also, if you're self-employed, you may be able to deduct the entire cost of the lease from your taxes, which may reduce the true cost of the lease (depending upon your tax bracket).

What is the 90% rule in leasing?

The 90% rule in leasing is an accounting guideline for classifying leases, stating that if the present value (PV) of a lessee's minimum lease payments equals or exceeds 90% of the leased asset's fair market value (FMV), the lease should be treated as a finance lease (or capital lease) rather than an operating lease, reflecting essentially a purchase for accounting purposes. This rule helps determine if the lease transfers substantially all the risks and rewards of ownership, requiring balance sheet recognition of the asset and liability. 

Can an LLC write off a car purchase?

The method depends on the vehicle type, usage, and tax strategy, requiring careful record-keeping of business vs. personal use.

What is the 1% rule when leasing a car?

The "1% lease rule" is a guideline in both real estate (rental income should be 1% of property cost) and auto leasing (monthly payment ideally under 1% of MSRP), used for quickly assessing potential deals, though it's a simplified benchmark that doesn't account for all expenses or market variations.

Yes, you can write off 100% of a vehicle's cost in the first year for business use, but it generally requires the vehicle to be a heavy-duty truck, van, or SUV (over 6,000 lbs Gross Vehicle Weight Rating or GVWR) and used exclusively for business, leveraging Section 179 deduction and bonus depreciation. Lighter passenger vehicles have strict caps, even if used 100% for business, with maximum first-year depreciation limits (around $20,200 for 2025).
