Wales has run its own landfill tax since 2018. Here is how Landfill Disposals Tax works, the standard, lower and unauthorised disposals rates, and how it compares with landfill tax elsewhere in the UK.
What Landfill Disposals Tax Is
Landfill Disposals Tax (LDT) is a devolved Welsh tax, administered by the Welsh Revenue Authority, charged on taxable disposals of waste made to landfill sites in Wales. It replaced UK Landfill Tax in Wales from April 2018, following the devolution of tax-raising powers under the Wales Act 2014, and was one of the first two fully devolved, Wales-administered taxes, alongside Land Transaction Tax which replaced Stamp Duty Land Tax in Wales at the same time.
Who Has to Register and Pay
Operators of landfill sites in Wales that accept taxable waste generally need to register with the Welsh Revenue Authority, account for tax on the disposals they make, and file periodic returns. In practice, the cost of the tax is typically incorporated into the gate fee the operator charges businesses, contractors and local authorities to dispose of waste at the site, rather than being billed separately to whoever brings the waste.
Standard, Lower and Unauthorised Rates
Mirroring the structure of the UK Landfill Tax it replaced, Landfill Disposals Tax applies a standard rate to most active waste (broadly, more polluting or biodegradable material) and a lower rate to specified less-polluting, inert materials such as rock, soil and qualifying building waste. A significantly higher unauthorised disposals rate applies where taxable waste is disposed of at a site that is not an authorised landfill facility, aimed at deterring illegal dumping and fly-tipping. Rates are reviewed periodically, so check the Welsh Revenue Authority's current published figures rather than relying on a previous year's rate.
Reliefs and Exemptions
Landfill Disposals Tax includes reliefs and exemptions broadly modelled on the former UK Landfill Tax regime, such as relief for waste arising from the reclamation of contaminated land in qualifying circumstances, and exemptions for material used for permitted site restoration or engineering works, subject to specific conditions and evidence requirements. Given the technical nature of these rules, operators should consult Welsh Revenue Authority guidance to confirm whether a specific waste stream qualifies.
How It Compares With the Rest of the UK
UK Landfill Tax, administered by HMRC, continues to apply to landfill disposals in England and Northern Ireland, while Scotland runs its own equivalent, Scottish Landfill Tax, administered by Revenue Scotland. Because each nation now sets its own rates and detailed rules independently, the standard rate, lower rate and specific reliefs can differ between Wales, Scotland and England/Northern Ireland, which matters for businesses moving waste across borders within the UK -- the tax that applies depends on where the waste is actually disposed of, not where it originated.
Frequently Asked Questions
What is Landfill Disposals Tax?
Landfill Disposals Tax (LDT) is a devolved Welsh tax, administered by the Welsh Revenue Authority (WRA), charged on taxable disposals of waste to landfill sites in Wales. It replaced UK Landfill Tax in Wales from April 2018, following devolution of tax powers under the Wales Act 2014, and is one of the first fully Welsh-administered devolved taxes alongside Land Transaction Tax.
Who has to register and pay Landfill Disposals Tax?
Landfill site operators in Wales that accept taxable waste for disposal generally need to register with the Welsh Revenue Authority, account for tax on disposals made, and submit periodic returns. The tax is typically built into the gate fee the operator charges businesses and local authorities for disposing of waste, rather than being charged separately to whoever brings the waste to the site.
What are the standard and lower rates?
Like the UK Landfill Tax it replaced, Landfill Disposals Tax has a standard rate that applies to most active (biodegradable or otherwise more polluting) waste, and a lower rate that applies to specified less-polluting, inert materials such as rock, soil, and building waste meeting the qualifying conditions. Rates are reviewed periodically by the Welsh Government, so always check the Welsh Revenue Authority's current published rates rather than assuming they match either a prior year or the UK Landfill Tax rate.

What is the unauthorised disposals rate?
A significantly higher unauthorised disposals rate applies to taxable disposals made at a place that is not an authorised landfill site -- essentially targeting illegal or fly-tipped waste disposal -- as a deterrent, alongside other enforcement powers the Welsh Revenue Authority and Natural Resources Wales can use against illegal waste operations.
How does this compare with Landfill Tax in the rest of the UK?
UK Landfill Tax, administered by HMRC, continues to apply in England and Northern Ireland (Scotland has its own equivalent, Scottish Landfill Tax, administered by Revenue Scotland). Because each nation now sets its own landfill tax rates and rules independently, the standard rate, lower rate and specific exemptions can, and sometimes do, diverge between Wales, Scotland, and England/Northern Ireland, so cross-border waste movements need to account for wherever the waste is actually disposed of.
Are there any reliefs or exemptions?
Landfill Disposals Tax includes reliefs and exemptions broadly modelled on the former UK Landfill Tax regime, covering categories such as waste from the reclamation of contaminated land in certain circumstances, and material used for landfill site restoration or engineering works subject to specific conditions. The detailed rules on qualifying materials and evidence required are technical, so operators should check Welsh Revenue Authority guidance directly.
Why was landfill tax devolved to Wales?
The Wales Act 2014 devolved responsibility for landfill tax and stamp duty land tax (subsequently replaced in Wales by Land Transaction Tax) to the Welsh Government and Senedd, allowing Wales to set its own rates and administer its own tax base for these areas rather than relying on UK-wide HMRC-administered taxes, as part of a broader move towards greater fiscal devolution across the UK's nations.
