We’ve just added a small but incredibly helpful feature to the system: effective dates for tax information, e.g. information that comes from P2C files.
How is this useful? In exceptional circumstances, Revenue may issue an updated P2C in the middle of the year. This may be to correct the tax credit or for other reasons. Difficulties may come in a few months down the line, when there’s no record of exactly when the new P2C came into effect, and indeed what the changes were.
We now record an effective date and keep track of the previous values for the above cases. This will enable you to troubleshoot tax queries related to updated P2Cs with ease.
