Landfill tax is one of the most complex and heavily enforced areas of UK environmental taxation. The regime is highly technical, fact‑sensitive and increasingly subject to coordinated action by HMRC, the Environment Agency and the Joint Unit for Waste Crime. Errors in classification, misdescription of waste or weaknesses in documentation can give rise to significant tax exposure, penalties and, in some cases, criminal investigation.
We advise landfill operators, waste processors, brokers, hauliers, local authorities, developers and end‑users on landfill tax across the full lifecycle — from determining liability and strengthening compliance, through to defending enquiries, assessments and enforcement action. Our advice combines deep technical expertise with a practical understanding of waste operations, treatment processes and supply‑chain risk.
Landfill tax disputes and compliance issues frequently turn on detailed questions of fact as well as law. We are instructed on matters involving waste classification, qualifying materials, fines, exemptions, site engineering and evidential standards, often where significant sums are at stake.
Our work in this area draws on extensive experience advising on some of the most complex landfill tax issues affecting the sector. We understand how landfill sites operate in practice, how waste is generated, treated and described across the supply chain, and how HMRC approaches risk, enquiry and enforcement.
Resolution Tax is a member of the Environmental Services Association, the trade body representing the UK resource and waste management sector.
Landfill tax is charged on waste disposed of at landfill sites, whether or not the site is authorised. Two rates apply: the lower rate for qualifying inert materials and the standard rate for other waste.
We advise clients on:
There are further exceptions for materials used in site restoration and engineering works, and for materials that are reused. These rules are complex and frequently misunderstood. We assist clients in analysing whether materials qualify for exception and in preparing documentation capable of supporting their accounting position on enquiry.
Eligibility for the lower rate of landfill tax is governed by the Landfill Tax (Qualifying Material) Order 2011 and is a frequent source of dispute.
We advise on waste classification and lower‑rate eligibility, including disputes involving:
Our experience includes defending challenges to lower‑rate claims and advising on how to structure processes and documentation to withstand scrutiny.
Fines are particles produced by waste treatment involving mechanical processes such as trommelling, screening or soil washing. Where the statutory conditions are satisfied, qualifying fines may be liable to the lower rate of landfill tax.
We have significant experience advising on disputes concerning fines derived from the processing of mixed waste inputs, including challenges to sampling, composition and evidential methodology.
Landfill tax risk often arises at the interface between waste treatment and disposal. We advise on how treatment processes affect landfill tax outcomes, including the classification of treated outputs, the interaction with lower‑rate rules and the evidential standards required to support tax positions.
Excess water content can materially affect landfill tax liability. In certain circumstances, waste producers may discount the water content of waste when calculating taxable weight.
We advise on the operation of water‑discount agreements, including:
Landfill tax evasion is a central focus of the Government’s environmental crime strategy. Enforcement activity is increasingly coordinated between HMRC, the Environment Agency and the Joint Unit for Waste Crime, and is often supported by data analytics and site inspections.
Waste crime — including illegal dumping, misdescription of waste and deliberate under‑accounting — can result in severe civil and criminal consequences, including:
While enforcement action is directed at criminal actors, legitimate operators are frequently exposed to liability, penalties and reputational risk. Brokers, processors and hauliers may also face exposure under the Corporate Criminal Offence of failure to prevent the facilitation of tax evasion.
The CCO regime creates criminal liability where a business fails to prevent the facilitation of tax evasion by employees, agents or contractors. In the waste sector, risk is heightened where subcontractors misdescribe waste or falsify documentation.
We advise clients on:
We support clients at every stage of landfill tax risk and dispute management, including:
Our advice is pragmatic, senior‑led and grounded in a detailed understanding of how landfill tax operates in practice. We focus on resolving issues efficiently while protecting both financial and reputational interests.
