Mid-Career Sweet Spot

This salary range often represents strong mid-career positions. You're still entirely in the basic rate tax band (20%), making raises very tax-efficient.

  • Salary sacrifice for pension can be very efficient at this level
  • Consider hybrid or remote roles - commuting costs can eat into raises
  • This is often the best time to change industries for a salary bump
  • Skills training and certifications can lead to significant jumps
