QX80 Section 179 Guide: 2026 Tax Write-Offs for Businesses

Published on Jan 15, 2026 by Ryan Dunn

Key Business Takeaway

For the 2026 tax year, the INFINITI QX80 remains a premier tax-saving asset for Northeast Ohio business owners. Thanks to its Gross Vehicle Weight Rating (GVWR) exceeding 6,000 lbs, the QX80 qualifies for significant accelerated depreciation under Section 179. By combining the SUV expense cap with 2026 bonus depreciation, businesses can potentially write off a vast majority of the purchase price in year one, drastically reducing their taxable income.

How to Claim a Significant Tax Write-Off for Your QX80 Using Section 179

As a business owner in Beachwood or the greater Cleveland area, your vehicle is more than just a commute—it’s a mobile office and a tool for growth. The 2026 INFINITI QX80 is engineered to meet the heavy-duty demands of a growing company, but its most impressive "spec" might be its eligibility for the Section 179 tax deduction. This IRS provision allows businesses to deduct the purchase price of qualifying equipment and vehicles immediately, rather than spreading the depreciation over five or more years.

The Mathematical Breakdown for Beachwood Businesses: Why 6,000 lbs GVWR Matters

The "magic number" for business vehicle deductions is 6,000 lbs GVWR (Gross Vehicle Weight Rating). Vehicles under this weight are classified as "luxury passenger autos" and are subject to strict annual depreciation caps. However, because the 2026 INFINITI QX80 has a GVWR of approximately 7,810 lbs, it falls into the "Heavy SUV" category, unlocking much larger first-year write-offs.

A Hypothetical 2026 Tax Scenario:

Suppose your Beachwood-based consultancy or firm purchases a new 2026 QX80 for $100,000 and uses it 100% for business. Here is how the 2026 tax math might look:

Step Deduction Type Estimated Amount
1 Section 179 SUV "Heavy" Cap (2026 Estimate) $32,000*
2 2026 Bonus Depreciation (Remaining basis x 20%) $13,600
Total Total Year-One Potential Deduction $45,600

*Based on projected inflation-adjusted caps from the previous $31,300 limit.

In this example, nearly 46% of the vehicle’s cost could be written off in the first year alone. If your business is in a 25% tax bracket, that is an immediate tax savings of $11,400, effectively lowering the cost of your QX80 to $88,600 before you even consider the standard depreciation available in years 2 through 5.


Can my business get a 100% tax write-off for a QX80?

While the "Heavy SUV" Section 179 cap limits the immediate deduction to roughly $32,000, businesses often reach a 100% total write-off by combining Section 179 with the standard 5-year MACRS depreciation schedule. In 2026, the bonus depreciation rate is scheduled at 20%, which provides a significant "boost" to the initial Section 179 amount.

To qualify for these "Heavy SUV" benefits, the vehicle must:

  • Be purchased or financed (not leased) by the business.
  • Be placed in service (available for use) by December 31, 2026.
  • Be used more than 50% for business. (Note: The deduction is pro-rated based on business-use percentage. 100% business use yields the maximum deduction).

Strategic Planning: The "Placed in Service" Deadline

The IRS is strict about timing. To claim the deduction on your 2026 return, the QX80 must be "placed in service" before the year ends. This means the vehicle must be on your lot and ready to work—simply signing the paperwork isn't enough. For Beachwood businesses looking to maximize their year-end planning, starting the selection process in the Fall is critical to ensure delivery and compliance.


The 2026 INFINITI QX80 offers more than just the "World’s Best Cabin"—it offers a strategic financial advantage for the Northeast Ohio business community. By turning a necessary business expense into a powerful tax shield, you can upgrade your professional image while keeping more capital in your company.
