Yes, you can potentially write off 100% of a vehicle weighing over 6,000 lbs (GVWR) using Section 179 deduction, but it depends on the vehicle type (heavy SUV/truck vs. regular car) and its primary business use (over 50%), with special rules for SUVs capping deductions at around $31,300 for the first year, while true work trucks/vans over 6,000 lbs GVWR can often get 100% expensing in the first year.
Although the IRS limits your 179 deduction for cars over 6,000 pounds, you can depreciate the remaining cost with regular depreciation. But for cars under 6,000 pounds, there's one more restriction, as the IRS caps the max amount you can depreciate for each following year.
If your vehicle is strictly used for business purposes and meets certain criteria (including vehicle type and weight), you may be eligible to deduct 100% of the purchase price in the year it is placed in service. This is typically achieved through a combination of Section 179 expensing and bonus depreciation.
If the vehicle weighs more than 6,000 pounds and is used more than 50% for business, you can write off up to $28,900 in the first year, and potentially even more with bonus depreciation. Let's break it down: Buy a qualifying vehicle for $60,000, and you could write off a large portion of that cost in year one.
For heavy vehicles, those with a gross vehicle weight rating (GVWR) above 6,000 pounds, some vehicles may qualify for larger first-year deductions, but passenger-type SUVs (and certain similar vehicles) are subject to a $31,300 Section 179 cap in 2025, even if they exceed 6,000 pounds GVWR.
You could write off all or some of your original purchase price in the first year, using depreciation, the Special Depreciation Allowance, or the Section 179 deduction or a combination of the methods. These deductions allow business owners to write off the purchase price of a car.
Cars that qualify for 100% capital allowances (First-Year Allowance) are brand new, fully electric cars with zero CO2 emissions (0 g/km), allowing businesses to deduct the entire cost from taxable profits in the year of purchase, provided they meet environmental and usage conditions and aren't second-hand. This significant tax relief applies to new, unused zero-emission vehicles, including certain electric vehicles and even some traditional black cabs, but not hybrids or used EVs.
Bonus depreciation is back. Business owners got their wish in 2025 when Congress made 100% bonus depreciation permanent. The provision, which was initially part of the 2017 Tax Cuts and Jobs Act (TCJA), began to phase out in 2023.
Instead of spreading deductions out over several years, you can take a 100% deduction in year one. The OBBB Act reinstated 100% bonus depreciation starting in 2025, reversing the scheduled phase-down. Not all vehicles are treated the same under the tax code.
Many business expenses are 100% deductible, including advertising, employee wages, rent, supplies, and certain business meals like company parties or meals for the public, while personal deductions like student loan interest or charitable donations (depending on the type) can also be fully deductible for individuals. The key is that the expense must be "ordinary and necessary" for your trade or business or meet specific IRS criteria, often differentiating from the 50% rule for client meals.
A common question in the minds of many small business owners is whether an LLC can write off a car purchase. The short answer is yes, provided the vehicle is used for business purposes, subject to the rules laid down by the IRS.
For tax year 2025, a vehicle with a GVWR over 6,000 pounds can offer significant tax deductions, primarily through Section 179 expensing, allowing immediate write-offs for business use, though SUVs have a $31,300 cap, while heavy trucks/vans (over 6,000 lbs GVWR) can qualify for much larger first-year deductions, potentially up to 100% with bonus depreciation, for qualifying business use and placement in service by year-end.
A recent tax law ("One Big Beautiful Bill") introduced a new $6,000 bonus deduction for Americans aged 65 and older, available for tax years 2025-2028, reducing taxable income, not the tax itself, with income phase-outs starting at $75,000 MAGI for singles and $150,000 for joint filers. This deduction adds to existing standard deductions, provides up to $12,000 for couples, and requires a Social Security number and filing status other than Married Filing Separately.

Bonus depreciation has no annual limit on the deduction. Section 179 deductions are also limited to annual taxable business income, meaning that a business cannot deduct more money than it made. Bonus depreciation does not have this limit and can be used to create a net loss.
In general, the OBBB provides a permanent 100‑percent additional first year depreciation deduction for qualified property acquired, or specified plants that are planted or grafted, after Jan. 19, 2025.
Due to a tax provision in the One Big Beautiful Bill, assets placed in service Jan. 20, 2025, and after are eligible for 100% bonus depreciation (full expensing). That means you can write off the entire purchase amount the same year you place it in service.
The main downsides of bonus depreciation include losing future deductions by taking them upfront, potentially increasing future taxable income, facing higher "recapture" taxes if the asset is sold, and dealing with complex rules or state-level nonconformity, making it less beneficial for short-term investors or those in lower tax brackets who might need deductions later. It also creates large upfront tax benefits that might not align with book income, affecting financing, and rules change frequently, requiring constant tax planning.
Disadvantages of Car Allowances
Car allowances do not ensure coverage of all vehicle-related expenses. Employees bear responsibility for insurance, maintenance, depreciation, and other costs. Because the IRS treats most car allowances as taxable income, the take-home amount may fall short of actual expenses.
Individuals and Partnerships, such as landlords and property investors, must be liable for Income Tax. Entities that are exempt from these taxes, such as pension funds, government bodies, charities, and public sector entities such as the police force, cannot claim capital allowances.
You can claim a maximum of 5,000 work-related kilometres per car. You need to keep records that show how you work out your work-related kilometres.
