Good tax planning make best use of 401k and other tax advantaged plans there are these Roth planes for example.

A FANG developer in London has even more opportunities

Max out your pension (Tax relief at 40%) plus presumably an employer match around 5-8%

Put £20k a year into a Stocks and Shares ISA - which puts that beyond tax for income and CGT (apart from stamp duty on share purchases)

Put £30k into premium bonds and than start thinking about VCT's and EIS

This is ignoring any shares scheme you are in
