To claim your car as a business expense, you must be self-employed or a business owner and choose between the Standard Mileage Method (miles x IRS rate) or the Actual Expense Method (tracking gas, repairs, insurance, etc.), calculating deductions based on your business-use percentage. Meticulous records of dates, destinations, business purposes, and mileage are essential for substantiating your claim, often filed on Schedule C (Form 1040).

Can an LLC write off a car purchase?

Yes, an LLC can write off a car purchase as a business expense, either by deducting the full cost in the first year using Section 179 and bonus depreciation (especially for heavy SUVs/trucks over 6,000 lbs), or by deducting actual expenses (gas, insurance, repairs) or the standard mileage rate over time, provided the car is used more than 50% for business. The method depends on the vehicle type, usage, and tax strategy, requiring careful record-keeping of business vs. personal use. 

How do you write off your car as a business expense?

Can a car be 100% tax deductible?

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).

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).

What is the IRS hobby income limit?

The IRS doesn't have a specific dollar limit for hobby income; instead, it focuses on profit motive: if you intend to make a profit, it's a business, but if it's for fun, it's a hobby, and you must report all income but can't deduct losses. Key is that you report all hobby income on Form 1040 as "other income," and if net earnings from self-employment are $400 or more, you owe self-employment tax, even if it's a side gig. The main difference from business is that you can't deduct hobby expenses (under current law) and must report all profits.
