Does custom tooling qualify for the R&D tax credit?

Custom tooling may need review when the work involves technical uncertainty, design alternatives, testing, or process development. Routine fabrication of known tooling generally needs to be separated from qualified research activity.

What precision machining activities may qualify?

Potential activities may include CNC process refinement, fixture design, die modification, prototype tooling, tolerance improvement, material testing, and production trial work. Eligibility depends on project facts and documentation.

Do failed tooling projects qualify for the R&D tax credit?

Failed tooling projects may still need review if the company tested alternatives, evaluated technical issues, or used results to guide further design or process changes. A failed result does not automatically prevent eligibility.

What records support a tool and die R&D tax credit claim?

Helpful records may include CAD files, tooling drawings, CNC revisions, test run reports, dimensional inspection data, production trial records, material specifications, quality reports, project timelines, and employee time records.

Can Ohio tool and die shops claim R&D credits?

Ohio tool and die shops may need to review R&D credit eligibility when projects involve custom tooling, machining improvements, fixture development, die changes, testing, or technical problem-solving supported by documentation.

Tool and Die R&D Tax Credit Guide for Manufacturers

Tool and die shops, precision manufacturers, and machining companies often perform technical work that may support an R&D tax credit review. The tool and die R&D tax credit opportunity depends on whether the company is developing or improving tooling, dies, fixtures, machining methods, or production processes through documented technical experimentation.

Since 2004, RCG has completed more than 25,000 R&D tax credit studies and identified over $750 million in tax savings. RCG’s team includes CPAs, tax specialists, engineers, technical writers, and architects who support federal and state R&D Tax Credit studies with audit-ready documentation.

RCG provides R&D Tax Credit support for tool and die shops and precision manufacturers across Ohio, including companies in Dayton, Springfield, Lima, Findlay, Toledo, Mansfield, Akron, Canton, and surrounding machining and manufacturing communities.

Tool and die manufacturing often involves custom technical problem-solving. A company may need to determine how to achieve tighter tolerances, improve repeatability, reduce defects, support a new material, improve cycle time, or make a production process more reliable.

A precision machining tax credits review may involve design changes, tooling trials, fixture development, die modifications, CNC programming challenges, material testing, or process refinement. Eligibility depends on whether technical uncertainty existed and whether the company evaluated alternatives through a documented process.

Tooling or Machining Activity	Why It May Need R&D Review
Custom die development	May involve testing geometry, tolerances, durability, or production repeatability.
Fixture or jig design	May support accuracy, alignment, cycle time, or part consistency.
Tooling modification	May involve resolving defects, wear issues, fit, finish, or material behavior.
CNC process refinement	May involve testing feeds, speeds, tooling paths, tolerances, or finish quality.
Prototype tooling	May involve evaluating design alternatives before full production.

Tooling innovation incentives should be reviewed based on technical facts, not broad labels. A project is not automatically eligible because it involves a custom tool or die. The company should be able to show what uncertainty existed, what alternatives were tested, what technical decisions were made, and how the results affected the final tooling or process.

Useful documentation may include CAD files, tooling drawings, CNC program revisions, test run records, production trial reports, dimensional inspection data, engineering notes, project timelines, material specifications, quality reports, and employee time records.

Documentation is especially important because qualified and nonqualified activities may occur within the same project. Custom engineering, testing, and process development may need review, while routine production, standard machining, maintenance, or repeat builds generally need to be separated.

Tool and die projects may need review when the work involves technical uncertainty related to material performance, dimensional control, production repeatability, forming behavior, tool wear, machine capability, or part quality.

A shop may test multiple die designs to improve durability, adjust fixture geometry to reduce variation, refine CNC programs to achieve tighter tolerances, or develop tooling for a new component. A project may also involve testing whether a design can be manufactured at production scale while meeting customer requirements.

These activities may support a review when they involve experimentation and documentation. Eligibility is not based on whether the project is difficult or custom. The analysis should focus on the technical uncertainty and the process used to resolve it.

Some tool and die work may be routine and should be separated from potentially qualified research. This can include repeat production, standard machining, tool maintenance, cosmetic adjustments, ordinary repair, and work performed after the technical uncertainty has been resolved.

For example, producing a known die from an established design may not support the same analysis as developing a new die configuration to solve tolerance, durability, or repeatability issues. The review should identify where technical development began, what was tested, and when the uncertainty was resolved.

Can tool and die shops claim the R&D tax credit?
Tool and die shops may qualify when they perform documented technical work to develop or improve tooling, dies, fixtures, machining methods, or production processes. Eligibility depends on technical uncertainty, experimentation, qualified expenses, and supporting records.
Does custom tooling qualify for the R&D tax credit?

Can Ohio tool and die shops claim R&D credits?
Ohio tool and die shops may need to review R&D credit eligibility when projects involve custom tooling, machining improvements, fixture development, die changes, testing, or technical problem-solving supported by documentation.

The tool and die R&D tax credit opportunity can be relevant for shops performing documented tooling development, fixture design, CNC refinement, production testing, or engineering-based problem-solving. Eligibility is not automatic, and supportable documentation is essential.
