Self Assessment tax refund

Hi there, I have been waiting for a self assessment tax refund which was filed in August. The total amount was £920. I rang 6 weeks ago to inquire about why it was taking so long and was informed it had been pulled for additional security checks. To this day, I’ve yet to receive my refund and I am wondering why it is taking so long? Any insight as to what is going with this would be appreciated thanks.

Hi Hayden,
If selected for additional security checks we would need to access your record to check on the progress.

Thank you.
