Scotland’s new Aggregates Tax will begin on 1 April 2026, replacing the UK‑wide Aggregates Levy for material commercially exploited in Scotland. Revenue Scotland will collect the tax, with rates set through the Scottish Budget, according to the Scottish Government. (gov.scot)

In the Scottish Budget 2026‑27, ministers confirmed a starting rate of £2.16 per tonne from 1 April 2026. For context, a 10,000‑tonne road base order would carry £21,600 in tax at the point of commercial exploitation-a line item project managers should now be costing. (gov.scot)

Who needs to act: any business that ‘commercially exploits’ aggregate in Scotland-quarry operators, importers, or suppliers into Scotland-must enrol with Revenue Scotland. Enrolment is open and typically takes around three to four weeks; groups can appoint a representative member, and producers of only exempt aggregate must notify rather than register. (revenue.scot)

Cross‑border rules matter. From 1 April 2026, Scottish Aggregates Tax applies to commercial exploitation in Scotland, while the UK Aggregates Levy continues in England, Wales and Northern Ireland. HMRC and Revenue Scotland have aligned rules so the supplier pays the tax of the destination country, with credits to prevent double charge where appropriate. (revenue.scot)

Contract pricing needs a fresh check for jobs spanning the change. Treat the charge as a separate line on quotes and invoices, revisit ‘change in law’ clauses on fixed‑price work, and confirm with clients how SAT will be passed through. Public‑sector frameworks will expect clear disclosure on tax within materials pricing.

Operationally, think in tonnage and traceability. Revenue Scotland’s enrolment asks for estimated annual tonnage by activity-quarrying, sand and gravel, importing from outside the UK, or using a mobile crusher-as well as volumes you expect to be exempt, relieved or exported. Anyone registering before go‑live must still enter 1 April 2026 as the first commercial exploitation date because the regime starts that day. (revenue.scot)

Compliance is not optional. The Act brings a penalty framework in line with other devolved taxes-fixed, daily and percentage‑based penalties-with additional SAT‑specific penalties such as failing to notify exempt production when required. Reviews and appeals run through Revenue Scotland and the Scottish Tax Tribunals. Supporting powers on set‑off and late‑payment penalties were switched on in January. (parliament.scot)

The policy intent is clear: encourage recycled materials and reduce primary extraction. That means projects reliant on primary aggregate-road sub‑base, asphalt plants, concrete and precast producers-will feel the cost most, while suppliers with credible recycled options could gain share as buyers recalibrate specifications. (gov.scot)

Cash flow and systems need attention now. Map product codes to tax treatment, update weighbridge and invoicing software to record tonnage and the SAT charge, and brief site teams on the triggers for commercial exploitation. With enrolment processing taking around three to four weeks, submit by early March to be confident of a clean 1 April start. (revenue.scot)

If you trade across the border, agree who accounts for the tax before dispatch. An English quarry shipping to Dumfries will account for SAT; a Scottish pit sending to Newcastle will remain within Aggregates Levy, with cross‑border credits preventing a double charge if the point of exploitation shifts. Keep robust delivery evidence. (revenue.scot)

A final practical note. The commencement instrument has now been made and laid (12 and 16 February 2026 respectively, per legislation.gov.uk), locking in the 1 April switch‑on. Revenue Scotland says further detailed guidance and webinars will follow, alongside phased enrolment. (revenue.scot)
