Deduction Table: 100% Business Use at 24% Tax Rate

The following table shows pre-computed Section 179 deductions for heavy trucks & vans (gvwr > 6,000 lbs) at common purchase prices. All figures assume 100% business use and a 24% combined marginal tax rate. Your actual deduction may vary based on your specific business-use percentage, tax bracket, and total qualifying purchases for the year.

Deduction Table: 80% Business Use at 24% Tax Rate

Many business owners use their vehicle for both business and personal purposes. The table below shows the impact of 80% business use on your deduction amounts. Remember, the vehicle must be used more than 50% for business to qualify for Section 179 at all.

How Section 179 Works for Heavy Trucks & Vans (GVWR > 6,000 lbs)

Heavy Trucks & Vans (GVWR > 6,000 lbs) represent the most tax-advantaged category for business vehicle purchases. With a GVWR exceeding 6,000 pounds and a non-SUV classification, these vehicles qualify for the full Section 179 deduction up to $1,220,000 with no SUV cap and no luxury automobile limits. This means the entire purchase price can potentially be deducted in the year the vehicle is placed in service.

For a $50,000 heavy truck used 100% for business, you can deduct the full $50,000 under Section 179. At a 24% tax rate, this generates approximately $12,000 in tax savings, bringing the effective net cost down to $38,000. This represents an effective discount of 24.0% on the purchase price.

The combination of full Section 179 eligibility plus bonus depreciation means that even very expensive heavy trucks can be substantially written off in the first year. For costs exceeding the Section 179 limit (unlikely for single-vehicle purchases), bonus depreciation at 60% applies to the excess, followed by regular MACRS depreciation on any remaining amount.

Example Vehicles in This Category

The following are common heavy trucks & vans (gvwr > 6,000 lbs) that businesses purchase for Section 179 deductions. Always verify the specific GVWR for your model and configuration, as different trim levels can have different weight ratings.

This list is not exhaustive. Any vehicle meeting the GVWR and classification requirements for this category qualifies for the same Section 179 treatment. Check the manufacturer's specifications for your specific vehicle before claiming the deduction.

Business Use Documentation Requirements

The IRS requires contemporaneous records to substantiate the business-use percentage of any vehicle claimed under Section 179. Acceptable documentation includes a written mileage log recording the date, destination, business purpose, and miles driven for each business trip. GPS-based mileage tracking apps like MileIQ, Everlance, or TripLog are widely accepted and reduce the record-keeping burden. Without adequate documentation, the IRS can disallow your entire Section 179 deduction and may impose recapture penalties.

If the business-use percentage drops to 50% or below in any year during the MACRS recovery period, you must recapture a portion of the Section 179 deduction. Recapture means adding back the excess deduction as ordinary income in the year the business use drops below the threshold. This is reported on Form 4797. For this reason, it is critical to maintain high business use throughout the vehicle's recovery period, not just in the year of purchase. Planning ahead for personal vehicle needs separately from your business vehicle can help ensure you maintain the required business-use threshold.
