Dividend

Spoke to HMRC last year on submitting my tax return as had a larger than normal dividend but for year 2022 it has gone back to £3712.71. The lady I spoke to said they would take the tax on my dividend through my tax code for 2022-23 and I didn't need to fill in a tax return. However, I've had the reminder to fill in a tax return. I don't know how to fill it in. My dividend tax has been put at 1859. Really appreciate some help.

Hi Allotment lady,
If you do not meet the criteria for Self Assessment then your UTR can be closed.
You can check at:
Check if you need to send a Self Assessment tax return
If you contact HMRC we can close your Self Assessment and amend the dividend income figure to the correct amount and then review the 2022/23 tax year through your PAYE records.
Self Assessment: general enquiries
Thank you.
