For the first time earnt over £1,000 in savings interest in 2023/24. I am a basic rate tax payer so I will need to pay tax on it. I understand that HMRC will contact me by October with the amount of tax I owe, but I haven't received a letter yet. I am employed full time and paid via PAYE and also do a small amount of freelance work so i have a self assessment account. I won't earn over £1000 in savings in interest in 2024/25 so I would prefer to pay this tax through self assessment than PAYE so I avoid paying too much in estimated tax next year. If I pay the tax via self assessment now, will HMRC still change my tax code for next year anyway? And can I ask for it to be changed back?
