Non Coded Income 6th April 2024 to April 2025

Hi, On checking online my income Tax summary for the current year 6th April 2024 to 5th April 2025 has a figure for Non Coded Income. I don't understand how this figure was arrived at given my latest self assessment tax return request sent on 6th April 2024 is for 6th April 2023 to 5th April 2024. Many Thanks

Hi Nick Brough,
If non PAYE income was declared on your last tax return then your tax code would be updated going forward with this figure as an estimate.
If you want to check what the non coded income refers to you will need to contact HMRC Self Assessment: general enquiries
Thank you.
