Scotland’s new aggregates tax now has a firm start date. Ministers have signed and laid the Aggregates Tax and Devolved Taxes Administration (Scotland) Act 2024 (Commencement No. 4) Regulations 2026, switching on section 1 (the tax) and section 2 from 1 April 2026. The same instrument brings the penalties chapter (sections 39–49) and section 50 on reviews and appeals into force. Signed by Ivan McKee on 12 February and laid before the Scottish Parliament on 16 February, it clears the way for go‑live at the start of the new financial year. (revenue.scot)

For price‑setters, the crucial detail is the rate. The Scottish Government has confirmed £2.16 per tonne from 1 April 2026, aligning with the UK Aggregates Levy for the first year to keep the transition stable. Finance minister Ivan McKee told MSPs on 3 February that alignment reduces budget risk while the system beds in. (gov.scot)

Revenue Scotland will run the tax and expects most returns and payments to be electronic. Registration is due to open in early 2026, with guidance already live for quarry operators, importers and intermediaries likely to fall within scope. That digital‑first approach mirrors existing devolved taxes and should shorten the learning curve for finance teams. (revenue.scot)

Cross‑border movements will need particular care. From 1 April 2026 the UK Government will operate a destination‑based rule for the UK Aggregates Levy, paired with credits to prevent the same consignment being taxed twice when it moves between Scotland and the rest of the UK. Revenue Scotland has published worked scenarios covering indirect transfers and documentation. (gov.uk)

The compliance spine goes live on day one. Expect fixed penalties for failures such as late filing, daily penalties where non‑compliance continues, and percentage charges for late payment or under‑declarations. SPICe notes additional aggregates‑specific penalties (for example, failing to provide a security or appoint a tax representative when required). Revenue Scotland has already updated guidance on late‑payment penalties and set‑off powers as further parts of the 2024 Act were commenced in January. (parliament.scot)

What does £2.16 per tonne mean in practice? A standard 20‑tonne tipper adds £43.20 of tax to the load if fully passed through. An asphalt plant consuming 200,000 tonnes of primary aggregate annually is staring at a £432,000 cost line. A mid‑sized quarry moving 500,000 tonnes would book £1.08 million of liability. These are headline maths to aid cash‑flow planning; actual pass‑through will vary by contract. (gov.scot)

For contract managers, this is a March‑to‑April issue as much as a 2026 issue. Fixed‑price civils work that spans 31 March may need split invoicing, with tax‑change clauses double‑checked. Buyers moving material across the border should confirm who is treated as the ‘producer’ for tax purposes and what evidence is needed to claim any credit and avoid double taxation. (revenue.scot)

Public bodies face the same arithmetic. A 50,000‑tonne road‑resurfacing programme would carry £108,000 of aggregates tax at the new rate before haulage and margin-modest in a major capital scheme, but material for highways maintenance budgets already under pressure. Early conversations with contractors about pricing assumptions will help avoid disputes.

Looking ahead, the rate will be set annually via the Scottish Budget, and secondary regulations will continue to refine administration. Revenue Scotland’s message is to register early, keep weighbridge and invoice data clean, and prepare to file online from April. Expect further webinars and final guidance in the run‑up to go‑live.
