Engineering R&D tax credits
R&D tax credits for engineering projects
Engineering claims often depend on whether the team had to overcome genuine technological uncertainty in the product, process, or system.
Start with the R&D tax credit calculator if you need a quick claim-value estimate before reading the detail.
Examples to review
Prototype design, tolerance challenges, material constraints, process optimisation, performance testing, and production methods may qualify when the solution was not readily deducible.
Cost areas
Staff, consumables, testing, software, subcontracted R&D, and externally provided workers can be relevant, subject to the detailed scheme rules and accounting-period facts.
Evidence that helps
Drawings, test results, failed approaches, technical meeting notes, supplier correspondence, change logs, and prototype records help link the claim to real problem solving.
Important note
R&D tax relief depends on scheme rules, company facts, accounting periods, and HMRC evidence standards. Treat this page as research support, not tax advice.
