Overpaid Tax from 2021-2022

Hi I did my self assessment for tax year 2021-2022 last year and paid tax due of £530. This tax calculation consists of pension payment from my personal account (i.e. not deducted by employer) of £1000. I've now realised that I actually made £1500 into my pension account (two transfers £1000 & £500). This additional pension transfer of £500 will reduce my tax. I've now tried to amend my tax return 2021-2022 by updating pension amount from £1000 - £1500 which has reduced the tax due from £530 to £330ish but the problem is that I've already paid the tax due of £530, therefore I should get back £200 rather then paying again £330. Where should I add the tax due I paid (£530) in the existing return? I think this will bring the tax overpayment to £200. Thank you

Hi Wingman30,
When you amend the tax return it will calculate the lower balance due which will then be reflected on the statement.
On the statement it will show the payments made and then show any refund due. 
Thank you.
