State pension was deferred.
It was taken in Feb 2020, back dated to Feb 2019. My initial assumption was that as the first payment was received Feb 2020, the full amount from start to 5.4.20 would be taxed in 2019/20. Having had a look, I now think the amount relating to Feb 2019 - 5.4.19 should be taxed in 2018/19 and the amount relating to 6.4.20 - 5.4.20 should be taxed in 2019/20.
It seems very odd though that the 2018/19 tax return had been completed and filed before notification was received of the amount that related to Feb 2019 - 5.4.19, so there is no choice but to amend the 2018/19 return and have tax paid late - is this correct?
Thanks for clarification.
