Capital allowances for Coventry manufacturers can provide substantial Corporation Tax relief on investment in CNC machines, industrial robots, automated handling equipment and production lines, but the correct relief depends on the asset, the legal ownership, whether it is new or second-hand and the structure of the business making the investment.
A production project should not be treated as one undivided capital cost. A new line may contain main-rate plant, special-rate assets, building works, electrical infrastructure, software and professional costs, each potentially following a different tax treatment.
Capital allowances for Coventry manufacturers buying plant and machinery
CNC machines, industrial robots and production machinery will commonly fall within plant and machinery allowances where they perform an active function in the manufacturing trade. For companies, qualifying new and unused main-rate plant can generally receive 100% full expensing, allowing the qualifying cost to be deducted from taxable profits in the period of acquisition.
The current full-expensing conditions for companies require qualifying plant and machinery to be new and unused and exclude cars. Full expensing is available only to companies, so an unincorporated manufacturer must consider other capital allowance routes.
The Annual Investment Allowance remains important even for companies because it can apply to most plant and machinery, including many special-rate assets and second-hand equipment, subject to the annual limit. The AIA is £1 million for 2026/27.
This means that the largest headline allowance is not automatically the most appropriate claim. The business should allocate expenditure between the available regimes rather than simply applying one percentage to the entire project.
Production lines often contain more than one class of expenditure
A manufacturing line may involve machinery, conveyor systems, extraction equipment, electrical installations, foundations, safety systems and alterations to the factory itself. The fact that the expenditure appears under one capital project code does not make every component main-rate plant.
Integral features of a building, including certain electrical and water systems, generally enter the special-rate pool. Structural works may instead fall outside plant and machinery allowances and potentially qualify for Structures and Buildings Allowance. Costs directly attributable to installing qualifying machinery can often follow the machinery, whereas expenditure that creates or improves the building must be analysed separately.
The general plant and machinery capital allowance rules exclude land and buildings themselves while permitting relief for qualifying business equipment. This makes the invoice breakdown and engineering specification important before the tax computation is prepared.
Capital allowances for Coventry manufacturers using full expensing, AIA and first-year allowances
For a company purchasing new main-rate machinery, full expensing will ordinarily provide a 100% first-year deduction and will therefore be more valuable upfront than the newer 40% main-rate first-year allowance. The 40% allowance became available for qualifying new and unused main-rate plant and machinery acquired from 1 January 2026 and can be relevant where full expensing is unavailable.
The 40% first-year allowance leaves the remaining 60% of expenditure available for writing-down allowances in later periods. From 1 April 2026 for Corporation Tax, the main writing-down allowance rate is 14%, while the special-rate writing-down allowance remains 6%.
Companies can also claim the 50% first-year allowance on qualifying new special-rate plant. However, where sufficient AIA is available, claiming 100% AIA against eligible special-rate expenditure can produce a larger immediate deduction. The order in which allowances are allocated can therefore materially affect cash tax.
Second-hand machinery and hire purchase require separate consideration
Used CNC machines and refurbished production equipment cannot qualify for full expensing merely because they are new to the buyer, but they may still qualify for AIA. This makes the distinction between new and second-hand expenditure important when a factory is expanded through acquired machinery.
Hire-purchase acquisitions can also qualify for capital allowances even though legal title passes later, provided the statutory conditions are met. Interest and finance charges are not part of the capital allowance claim.
Timing deserves particular attention where machinery is ordered in one accounting period but payment is deferred. Capital allowance legislation has specific rules for determining when expenditure is incurred, so the purchase order, contract and payment terms should be reviewed before assuming that the invoice date controls the claim.
A fixed-asset schedule should be prepared before filing
The company should maintain an asset-level schedule identifying the machine, acquisition date, new or used status, installation costs, pool classification and allowance claimed. Large projects should also reconcile supplier invoices to the engineering bill of materials so that qualifying machinery is not hidden inside a broader construction contract.
The resulting allowances should feed directly into the manufacturer’s Corporation Tax calculation. Where a new manufacturing line combines machinery, factory alterations, leased assets and significant electrical or structural works, specialist tax advice should review the project before the claim is fixed.
