The bad publicity given to shooting this year from recent tragic events in the news has not helped our sport and may unfortunately influence grant bodies when handing out grant aid to clubs. So any tax rebates from the IR are welcome.
I would add to the above that an increasing number of grant applications ask whether the club is a CASC. Whilst not having CASC status will normally not disqualify the club from submitting an application, you will have to explain why you have not applied to become one. In these cases CASC is an additional box "ticked".
