Manufacturing Company R&D Tax Credit and MACRS Depreciation Acceleration

The Problem

This precision manufacturing company produced aerospace and defense components requiring constant process innovation, material testing, and quality improvement. The company spent approximately $1.2 million annually on activities that qualified as research and development under IRC §41, but had never claimed the R&D tax credit. The prior accountant was unaware that manufacturing process improvements, tooling design, prototype development, and material testing constituted qualifying research activities.

Additionally, $2.8 million in CNC machines, lathes, presses, and testing equipment were being depreciated on standard 7-year MACRS schedules. No Section 179 elections had been made on qualifying equipment, and the company had not taken advantage of bonus depreciation provisions on any recent acquisitions.

AE Tax Strategy

1. R&D Tax Credit Under IRC §41 and §174

We performed a comprehensive R&D tax credit study identifying $1.2 million in qualifying research expenditures across four categories: wages for engineers and machinists performing qualifying activities ($680,000), supplies consumed in prototyping and testing ($195,000), contract research with metallurgical labs ($165,000), and cloud computing costs for CAD/CAM simulation ($160,000). Using the Alternative Simplified Credit method under IRC §41(c)(5), we calculated an annual R&D tax credit of $72,000. As a C-Corp, this is a dollar-for-dollar reduction against federal income tax liability. We also filed amended returns for two open years, generating additional credits of $128,000.

2. MACRS Acceleration and Section 179 Under IRC §168 and §179

We reviewed the entire $2.8 million equipment schedule and identified $890,000 in assets that had been placed on incorrect recovery periods or had not received Section 179 elections. CNC machines acquired in the current year ($420,000) were immediately expensed under Section 179. We filed Form 3115 to correct depreciation methods on older equipment, generating a Section 481(a) catch-up adjustment of $310,000. Ongoing annual depreciation optimization savings: $48,000.

3. Equipment Leasing Entity Under IRC §162

We established an equipment leasing LLC owned by the shareholders to hold and lease major equipment back to the C-Corp. This structure allowed lease payments to be deducted by the operating company under IRC §162 while the leasing LLC captured depreciation deductions at the individual level where they offset other income. Annual tax savings from entity layering: $22,000.

Before & After Comparison

Key Takeaways

• Manufacturing companies routinely qualify for the R&D tax credit under IRC §41. Process improvements, tooling design, prototype development, and material testing all constitute qualifying research activities.
• The Alternative Simplified Credit method typically yields credits of 5-7% of qualifying research expenditures and is simpler to calculate than the regular credit.
• CNC machines, precision lathes, and testing equipment qualify for both Section 179 immediate expensing and bonus depreciation. Companies depreciating these over 7 years leave substantial deductions unclaimed.
• Equipment leasing entities allow shareholders to capture depreciation at the individual level while creating deductible lease expenses at the corporate level.
