Impact is expected to result in:
 
  -  Lower consolidated taxes on income for all individuals with income of less than £175k.

  -  £1,280 a year more take home pay for someone on £35,000, a saving of only £229 a year for those on £100k, which is just below where the proposal would have made tax more expensive if it were not for the "hidden" 62% tax rate at £100k-£125k (the impact of that hidden rate is so material that instead of being more expensive at just over £100k, the SPP proposed rates do not drive higher tax costs until an income of £175k).

  -  higher rates of tax being aligned to higher income for far longer (i.e. a steeper cumulative rate curve that flattens out much later).  

  -  substantially more absolute tax being raised from high earners (e.g. an additional £131k a year at income of £1.5m), however the increased burden for the individual is comparatively low at just over £0.8m compared to just under £0.7m.
