Revenue Phased Payment Arrangements and Credit Score?

This is my first (and most likely only) year where I had to register with revenue for self assessment as I did some freelance work outside my normal PAYE job. Due to unforeseen circumstances I think I will be short ~8k (out of a total ~22k) owed next October (ideally I won't but there is a risk). I should be able to clear that within a few months post-deadline, maybe through a PPA. Would this affect my credit score going forward?

I see here that 'The following information is not included on the Central Credit Register....Tax liabilities'.....so I'm hoping that means it won't affect my credit.

Correct. Revenue does not report debts to CCR.

However a lender will look at your outgoings and may well query what it is.

Ok thanks. I don't plan on going near a lender until it's all cleared (and then probably not even for ~6 months or so) so that is good to hear.
