Child support calc and pension

[PostHeads123]

I pay child support based on gross earnings, I get a pension through work that they pay into and I pay 2% myself in. I want / need to increase my own contribution to 5%, would that be factored into how they calc my gross wage for to work out the child support payment as my income dropping ? I had a google and its a bit unclear, I think it would be taken into consideration but Im not sure ?

Thanks

The online CM calculator asks:

What is your weekly gross income?
This is income before tax and National Insurance but after pension contributions.

Which suggests it does.

I think you have to specifically notify CMS though as they access your P60 for the CM calculation which doesn't specify relief at source pension contributions.

They do take this into account.

Note that if you make significant pension contributions they reserve the right to investigate this and deem whether this is reasonable or whether it represents a diversion of income.
