Thank you T McGibney for your message - I actually thought that I would have owed them more. I thought it would have been about just over €1k rather than €800. I assumed my sterling account would have been taxed at 40% but perhaps it was taxed at 33%.
Thank you that link, Corola. I will look into that...and I know what you are saying Dr. Strangelove. It is a valid point, but I just kinda like the idea of clearing what I owe (and if I didn't, then presumably when I declare interest for 2025 I will have a similar adjustment to tax credits. Feels like it could be all a bit messy)
