Key point 17A on the Companies income tax return - IR4 is a calculatable field in our system. This means that E-File does not send us any figures. Instead - we automatically calculate it as we add up all the other tax credit return key points. Our old system operated similarly.

There is an issue when our new system does its automated calculation for IR4 Company income tax returns, it issues a NOA showing as previously $0.00 and as amended $[calculated figure] - where the calculated figure matches what was originally filed in E-File.

We are looking into this issue and will update this page once a change is made.
