A bill is currently being considered by the Scottish Parliament for the devolution of aggregates levy to Scotland with effect from 1 April 2026.
The proposed structure of Scottish Aggregates Tax is broadly similar to aggregates levy to avoid unintended consequences caused by differences in treatment within the UK, and so that it can be easily understood by taxpayers who are used to dealing with aggregates levy.
One of the most significant features that affected businesses will need to adapt to is the movement of aggregate into and out of Scotland. For registered taxpayers who exploit aggregate in Scotland and send it to a customer in the rest of the UK, they will need to claim a Scottish Aggregates Tax credit, and the UK customer will need to declare UK aggregates levy as they would for aggregate which is imported from outside of the UK. For aggregates producers in the rest of the UK sending aggregate to Scotland, they will need to claim a UK aggregates levy credit and they will also need to register for Scottish Aggregates Tax and file returns declaring the Scottish Aggregates Tax due.
And finally, not a change, but a ‘Did you know?’. Did you know that the territorial scope of aggregates levy is broader than most UK taxes?
The territorial scope of aggregates levy encompasses both the UK and UK waters, which are those areas of the Continental Shelf where the UK has rights over the seabed. This means that aggregates levy is highly unusual in that material can be brought into UK waters and used for construction purposes, triggering an aggregates levy liability, without being imported or subject to other UK taxes. Those most likely to be affected are those involved in construction activities associated with development of offshore wind farms, offshore oil and gas, and laying cables on the seabed.
