Table 3.C: Scottish income tax and Welsh rates of income tax in 2021-22: March 2021 forecast versus outturn
Income tax was devolved to the Scottish Parliament in 2016 and the Welsh Senedd in 2019. In this box we evaluated our March 2021 forecasts for 2021-22, and how they compared to the eventual outturn data. This was a particularly difficult period to forecast given the economy was recovering from the unprecedented impact of the Covid-19 pandemic. The double-digit difference between our initial forecast and the final outturn, for both Scotland and Wales, is largely explained by the faster-than-expected post-pandemic recovery.
Table 4A: Devolved property taxes in 2022-23: March 2022 forecast versus outturn
The land and buildings transaction tax (LBTT) was implemented in Scotland on April 1 2015 while the land transactions tax (LTT) began in April 1 2018. Both taxes replaced the UK Government’s stamp duty land tax but operate in similar ways. In this box we evaluated our March 2022 forecasts for 2022-23, and how they compared to the eventual outturn data. We explained the reasons behind the 1.4 per cent surplus for LBTT and the 9.6 per cent shortfall for LTT.
Chart 3.A: Line chart showing Scottish and UK marginal income tax and NICs rates in 2024-25
Income tax was devolved to the Scottish Government in 2016 and policy changes since then have led to a divergence with the UK Government’s income tax system. In this box we explored the costing of the Scottish Government’s December 2023 decision to introduce a new 45 per cent ‘advanced’ rate and to raise the ‘top’ rate to 48 per cent, including the potential behavioural responses.
