Working inside IR35 for the Public Sector.

Obviously, my taxes have increased significantly.

I have weighed up the option of putting money on my mortgage (net of tax) or making additional pension contributions...At the moment I have not been making pension contributions because I made the opposite decision (to pay down the mortgage) when I was outside IR35.

So, how do I make pension contributions inside IR35 where my agency (or their accountant) deducts tax at source? Do I have to make them net of tax and claim the tax on my self-assessment? Or can I get the agency to take it into account?

Thanks.
