Thank you for your enquiry,
This may because you have not made your voluntary payment directly to Inland Revenue but to your KiwiSaver scheme provider.
I can see your KiwiSaver scheme provider has advised Inland Revenue of your voluntary payment of $1050.00 when they requested your government contribution be applied to your account.
