Hello, I moved to the UK for my first post-University full time job in July of 2023 and a few days ago had the shock of remembering that I have ETF saving accounts in Germany that I may be liable to pay taxes for in the UK and am now slightly panicking. As the taxes are automatically withdrawn by the German authority from the accounts it simply skipped my mind. Both of my savings portfolios (ETF) combined have accrued roughly 4,600 EUR (~£3,873) in gains/value since the 01.01.2023. Could I please ask for some advice on wherever I need to report this income since it is already taxed in Germany or what my next steps would be? Thank you very much for any help in advance.
