From 1 April 2026, the Scottish Aggregates Tax (SAT) formally takes effect, alongside the penalty framework and the statutory routes for review and appeal of Revenue Scotland decisions. These measures implement core provisions of the Aggregates Tax and Devolved Taxes Administration (Scotland) Act 2024 and mark the transfer of responsibility for taxing the commercial exploitation of aggregate in Scotland from the UK levy to a devolved regime. (gov.scot)
In practical terms, the switch‑on of Part 1 allows Revenue Scotland to charge SAT on aggregate when it is commercially exploited in Scotland, with detailed concepts and processes defined in the Act and supporting regulations. The penalty provisions sit in Chapter 5 of Part 1 and the review and appeal provisions are provided for in Chapter 6, ensuring enforcement and redress are live from day one. (parliament.scot)
Who is affected is broad but clearly defined by official guidance. Quarry operators in Scotland, businesses importing aggregate from outside the UK for Scottish use, suppliers in England, Wales or Northern Ireland who sell into Scotland, and supply‑chain intermediaries may all be brought within scope depending on who is responsible for the point of commercial exploitation. (revenue.scot)
Operators should now complete Revenue Scotland’s two‑stage onboarding: enrol via the SAT form and, once invited, create a Scottish Electronic Tax System (SETS) account. Revenue Scotland indicates processing will typically take three to four weeks; early enrolment reduces the risk of delays at go‑live. Group registrations and exempt‑only notifications are available, and anyone registering before go‑live must use 1 April 2026 as the ‘first commercial exploitation’ date because the regime starts then. (revenue.scot)
The tax rate applying from 1 April 2026 is set at £2.16 per tonne. Ministers confirmed this alignment with the UK Aggregates Levy for the first year of operation to support stability during transition; any future rate decisions will be taken through the Scottish Budget. (parliament.scot)
Cross‑border rules are designed to avoid double taxation and to place liability where the commercial exploitation occurs. Revenue Scotland and HMRC have coordinated guidance so that, from 1 April 2026, UK Aggregates Levy is disapplied in Scotland and SAT applies to exploitation in Scotland, while levy continues elsewhere in the UK. Some rest‑of‑UK producers supplying Scottish customers may need to register for SAT. (revenue.scot)
From the commencement date, penalties will apply for failures such as not registering when required, not filing returns, or not paying tax on time. The framework provides for fixed, daily and percentage‑based penalties, mirroring approaches used for other devolved taxes to encourage compliance and provide proportional sanctions. (parliament.scot)
Taxpayers will also have access to statutory redress. Decisions made by Revenue Scotland in relation to SAT can be reviewed and, where appropriate, appealed in line with the procedures referenced in the Act, offering an internal review route and onward appeal to the Scottish Tribunals. (parliament.scot)
Several administrative powers supporting devolved tax management came into force earlier, including set‑off of debts, refusal of certain repayment claims where other taxes are unpaid, and regulation‑making powers on automation and communications. Revenue Scotland has updated guidance to reflect these changes ahead of SAT go‑live. (revenue.scot)
Immediate actions for businesses include confirming whether activities amount to commercial exploitation in Scotland, enrolling with Revenue Scotland, preparing systems to capture tonnages and any exempt or relieved uses, and assessing cross‑border responsibilities. With SAT forecast to raise material revenues in 2026‑27, early operational readiness will minimise compliance risk after 1 April. (revenue.scot)
