Manufacturing Equipment Depreciation

CNC Machines and Robotics: Tax Recovery in Capital-Intensive Shops

Modern CNC machining centers range from $50,000 for entry-level 3-axis mills to over $500,000 for high-precision 5-axis machining centers used in aerospace applications. Industrial collaborative robots (cobots) for pick-and-place or welding add another $30,000 to $150,000 per unit. All are classified as 7-year MACRS property under Asset Class 20.1 through 20.5 for manufacturing machinery.

A small precision machining shop acquiring a $200,000 CNC vertical machining center can leverage 40% bonus depreciation in 2025, generating an $80,000 first-year deduction. Section 179 can cover the remaining $120,000 in the same year if the business has sufficient taxable income, potentially expensing the entire machine in year one. For shops running thin margins on long-cycle projects, front-loading depreciation improves cash flow when revenue from the machine's output has not yet fully materialized.

Production Line Assets and Component-Level Tracking

Complex production lines present a unique challenge: a $1.8 million automated assembly line might consist of 40 distinct components—conveyor systems, vision inspection cameras, robotic arms, pneumatic actuators, and control panels—each potentially carrying a different MACRS classification and useful life. Manufacturing companies that track assets at the component level, rather than treating the entire line as a single asset, can claim disposal losses on replaced components without retiring the entire system.

When a conveyor motor assembly burns out after 6 years and is replaced at a cost of $35,000, the manufacturer must remove the replaced motor's remaining basis from the books—even if the overall line continues operating—and capitalize the new motor as a fresh 7-year asset eligible for bonus depreciation.

Tooling and Die Costs: Current Expense vs. Capitalization

Special tooling—molds, dies, jigs, and fixtures custom-built for specific production runs—often qualifies for immediate expensing under the tangible property regulations' routine maintenance safe harbor or as 3-year MACRS property. Production tooling with a useful life under one year is fully expensible as incurred. Longer-lived tooling above the de minimis threshold must be capitalized.

Many manufacturers negotiate with customers to recover tooling costs upfront as part of the program launch agreement, reducing the at-risk capital that must be depreciated. When tooling is customer-owned (title passes to the customer at delivery), the manufacturer may not capitalize or depreciate it at all—the full recovery comes through the program price rather than the tax depreciation schedule.
