Ok so I'm just about to employ a nanny for the first time and feel very out if my depth with the whole net vs gross salary thing. I understanf vaguely why its of benefit to me to agree a gross salary but am not sure of the advantages/ disadvantages to the nanny. Can anyone explain in case i get into the discussion? My plan was to stick the net rate she's requested plus tax code 747L into MrA calculator and show her the resulting gross £ as backup to the gross rate I'm proposing. She'll be doing 3 days a week for me - not sure if she has or plans to get a second job.
