Capital Allowances in 2026: Maximising Tax Relief on Business Investments

We believe that well timed investment decisions can significantly improve both operational efficiency and tax outcomes. In 2026, capital allowances remain one of the most valuable tools available to Irish companies seeking to reduce their corporation tax liability while reinvesting in growth.

Capital allowances allow businesses to claim tax relief on qualifying capital expenditure. Instead of deducting the full cost of an asset in the year of purchase, relief is generally spread over several years. This applies to assets such as plant and machinery, equipment, vehicles used for business purposes and certain fixtures and fittings.

Understanding what qualifies is essential. Not all expenditure is eligible. Routine repairs and maintenance are treated as revenue expenses, while capital allowances apply to assets that provide long term benefit to the business. Careful classification ensures that relief is maximised without risking compliance issues.

Timing can also influence the benefit. Bringing forward planned investment before year end may allow earlier relief and reduce taxable profits for the current accounting period. However, purchases should be commercially justified rather than purely tax driven. Cash flow impact must be considered alongside potential savings.

Industrial buildings and certain commercial property improvements may also qualify for allowances under specific conditions. In addition, businesses investing in energy efficient equipment may benefit from accelerated capital allowances where criteria are met. These incentives support both sustainability and cost reduction objectives.

Record keeping is critical. Invoices, payment records and clear descriptions of assets must be retained. If Revenue queries a claim, documentation should demonstrate that the expenditure qualifies and has been used for business purposes.

Capital allowances also interact with future disposal of assets. If equipment is sold, balancing charges or allowances may arise. Proper planning helps avoid unexpected tax adjustments.

For growing SMEs, capital allowances form part of a wider tax strategy. Coordinating investment decisions with profit forecasts, cash flow projections and long term expansion plans can enhance overall financial performance.

In 2026, businesses that review capital expenditure proactively are better positioned to maximise available reliefs while strengthening their operational capacity.
