Hi HMRC, I have been paid the 1st payment (22/23 tax fee $1000+ 23/24 pre-taxed 50% $500 on June 2023 ) & 2nd payment (23/24 pre-taxed 50% $500 on May 2024) when submitted self assessment tax return on 22/23, which included paid for Prepaid of 23/24. However, I didn't see the system automatic deduct that two times tax amount from my tax return 23/24 on 22May2024. And, I signed-in and checked there have show me "request a repayment" digit form in the item of "At the glance", which means I can apply for the refund from HMRC, however, that amount just claiming the 2nd payment of 23/24 prepaid 50%, is not 100% . So, what can I do? do HMRC would be deduct the 50% overpaid amount into my current tax refund?
