A couple of questions:
1) Is the money paid to the non-dep, or to the clmt?
If to the non-dep, it isn’t the clmt’s income. And, if the non-dep is not working 16+ hours per week, it won’t affect the non-dep deduction.
If the money is paid to the clmt, then a further question arises:
2) Is there any obligation for the £300?
If not, the payments would appear to be voluntary and, as such, would be disregarded in full.
Hope this helps.
