On Friday DF text me that he had received an official letter from his state pension provider from abroad requesting him to pay tax, and asked me to help with it. It turned out that this was the second letter they had sent him as he did not follow the instructions of the first letter to provide evidence of why he should not pay tax (he sent them an email in English telling them he is poor, instead of filling in the required forms etc in the local language). In order to help him I needed to ask some questions and as soon as we got to a challenging one, he told me to leave the matter, he didn't want my help and he will sort it out.
The problem is that he does not have the ability to sort it and the default position is that he will have to pay thousands of pounds in tax, which will leave him destitute. He will not know what to do to get an exemption because he barely speaks the local language whereas I am fluent in it, and he's already demonstrated by how he responded to the first letter that he can't do it. Would I be unreasonable to let him get on with it rather than force myself into his business?
As background, my parents have always made poor decisions which has resulted in lost money, and when I have tried to help them they have hugely distrusted anything I have done for them even though there is no reason to (think screaming at me that I am trying to do something bad to them by asking them questions about their income when helping them with applying for benefits). I feel like I don't see why I should keep putting myself in this situation but at the same time i don't want to see them struggling to buy food because they have a massive bill to pay as a result of their incompetence.
