For the new 2018–19 tax year, the Scottish higher-rate threshold has fallen further behind that in the UK, and two new income tax bands have been added in Scotland while the higher- and additional-rates have been increased. While most Scots will be either unaffected or pay slightly less in tax, overall the change will raise revenue as a result of higher earners paying more. This observation argues that while these changes represent small tweaks to the system rather than a major overhaul, differences between the Scottish and UK income tax systems could have significant implications for taxpayer behaviour going forward.
