Maximum AIA calculator

This calculator works out if your expenditure on plant and machinery can qualify for the AIA.

About this calculator

The calculator takes account of the change in the maximum AIA for accounting periods starting before 1 January 2019 and ending on or after that date. It also works out if the calculation can be made using whole months or whether days must be used instead, and which is the most advantageous.

How to use this tool

Click “Start” and enter the information requested in the blue cells. Click “Results” to see how much of your expenditure qualifies for the AIA and the maximum that could qualify.
