Having clients in both Scotland and Wales, I'm very aware that there are a number of differences in taxation, but what is the scope of these devolved taxes?
In Northern Ireland, Corporation Tax is devolved with the idea of harmonising the tax cross-border. This process collapsed when power-sharing fell through in 2017 and it hasn't been mentioned again, though it still remains devolved.
Scotland has all sorts of devolved powers such as Land and Building Transaction Tax and Scottish Landfill Tax. They set all rates and bands of Income Tax (except personal allowances) and half of the VAT collected there remains in the country.
Wales has its own Land Transaction Tax and a Landfill Disposal Tax and has partial Income Tax powers where they set its own 'Welsh' rate for each band.
One of the main differences between the countries is between Stamp Duty Land Tax (SDLT) in England and Northern Ireland, Land Building Transaction Tax (LBTT) in Scotland and Land Transaction Tax (LTT) in Wales. An example of this is on a £250,000 property purchase, for SDLT it would cost £2,500, for LBTT it's £2,100 and for LTT it would be £2,450, so there are differences.
When it comes to Income Tax on an annual salary of, say, £25,000 then England and Northern Ireland workers would pay £2,484.20, in Scotland, they pay £2,462.48 and Wales would be the same as England and NI for now. It is worth noting that the higher rate in Scotland is different.
There are plenty of other examples of differences between taxation in England, Wales, Northern Ireland and Scotland though I've covered the main ones. If you need to know something specific then I'm always here to help.
