The Section 179 Tax Deduction remains one of the most powerful incentives for businesses to invest in themselves. For the 2026 tax year, updated legislation has significantly increased deduction limits, making it more affordable than ever to upgrade your shop with new or used CNC machinery, spindles, and retrofits.
What is the Section 179 Deduction?
Section 179 allows businesses to deduct the full purchase price of qualifying equipment and software purchased or financed during the tax year. Instead of depreciating a new CNC machine over several years, you can write off the entire cost from your 2026 gross income.
2026 Deduction Limits & Details
The Internal Revenue Service has adjusted the following limits for the 2026 tax year to account for inflation and recent legislative changes:
- 2026 Deduction Limit: $2,560,000 Businesses can deduct the full cost of qualifying equipment up to a total of $2,560,000. This is a substantial increase over previous years, designed to encourage industrial growth.
- 2026 Spending Threshold: $4,090,000 The deduction begins to phase out dollar-for-dollar once the total amount of equipment purchased exceeds $4,090,000. This makes the deduction ideal for small to medium-sized manufacturing facilities.
- Bonus Depreciation: 100% Following recent extensions, Bonus Depreciation is set at 100% for 2026. This applies to equipment costs that exceed the $2,560,000 Section 179 limit.
Qualifying Equipment for CNC Shops
To qualify for the 2026 deduction, the equipment must be put into service between January 1, 2026, and December 31, 2026. Qualifying purchases include:
- New and Used Machinery: CNC routers, mills, lathes, and grinders.
- Technical Components: Replacement spindles, servo motors, and controller retrofits.
- Support Systems: Cooling solutions, filtered blower assemblies, and vacuum systems.
- Software: Off-the-shelf software used for business operations or manufacturing.

The “New vs. Used” Advantage
Unlike many other tax credits, Section 179 applies to both new and used equipment, provided the equipment is “new to you.” This is particularly beneficial for shops looking to acquire high-performance refurbished machinery or specialized replacement parts.
