I recently started a new job which has a nest pension. Some of my contributions are paid relief at source, some are salary sacrifice. I usually use FEIE to exclude my gross income so I have my employee contributions as post-tax for the US side (and try to keep a record of this). I know that I cannot exclude employer contributions.
The problem is with my current employer salary sacrifice contributions go into NEST as employer contributions, so there is no paperwork or record to separate salary sacrifice from "my end" (ie reduction in my agreed gross salary), from the employer 3% contribution. I am trying to keep some records of this myself, but wondered if anyone else had experience or received advise on how to manage this with NEST.
