“If you are in receipt of any income taxed through PAYE, it is worth checking your tax code to ensure HMRC have not included any incorrect adjustments that impact the amount of tax you are paying at source.
If you are unsure what any of the adjustments relate to, or believe your tax code to be incorrect, you can call the HMRC helpline on 0300 200 3300 and ask that they update your code in order that the correct amount of tax is being collected at source.”
