Hi Kezzy KM,
We are sorry to hear of the frustration caused by your request not having been applied.
This often occurs when we haven't received an estimate of your pay for the upcoming tax year.
We don't want to collect a prohibitively large amount of tax from your wage.
Contact us by webchat or phone here:
Self Assessment: general enquiries
We can either update your code, or offer alternatives.
Thank you.
