Response
I enclose a copy of the information you requested in relation to part two of your request.
Regarding part one of you request, the answer is set out below. Please note Scottish Income Tax was only introduced in 2017-18. There have been no years when all tax thresholds have been uprated in line with inflation. The information below sets out instances of individual thresholds being uprated by at least inflation since 2017-18.
Changes to the Personal Allowance have been included in the list below. Policy relating to the Personal Allowance is reserved. This means any changes made by the UK Government to this aspect of the Income Tax system apply to taxpayers in Scotland.
In 2017-18, the Personal Allowance increased by 4.5%, compared to CPI inflation of 1%. In 2018-19 the Personal Allowance increased by 3%, matching CPI inflation of 3%. In 2019-20 the Personal Allowance increased by 5.5%, the Basic rate threshold increased by 4.7% and the Intermediate rate threshold increased by 3.9% compared to CPI inflation of 2.4%.
