Qualified child part of Invalidity Pension Taxable?

[Waldmann]

My query please - is the "increase for qualified child" portion of the Invalidity Pension Taxable?

I understand that the Invalidity Pension (€193.50 per week) is a taxable source of income but I cannot find a clear direction re the taxability or otherwise of the portion (€44.70) that is payable for a qualified child?

I understand that Jobseeker's benefit. for example, is taxable (subject to disregard of €13 per week) but that increase for qualified child part of that benefit is not taxable.......

Thanks in advance for any advice
