Pension Payments (outside of tax year) on Self Assessment

F_T_Buyer

Hi All
I'm just filling in my self assessment, and I've noticed my employer sent my March pension payment late and it actually arrived with Aviva after 6th April.
I still want to claim this in my 19/20 tax year, I assume there is no problem doing this? Obviously I won't include this when I do my 20/21 self assessment.

Also, could I send a payment now to reduce my tax in the last year? There is no option is Aviva to say it's for the last tax year. Basically I want to reduce my child benefit tax charge, as I earn just over the higher rate limit.

Thanks!

Thanks. 

It's a shame because my employer never gives me a P11D until July usually (I always pester for it), and this year my health benefit has jumped massively - getting older I guess. Also, as I've become a father in the last tax year I wanted to make sure I put everything over 50k into my pension to avoid the higher rate tax child benefit charge.
