Chart 1 shows the weight of and tax due on waste disposed to landfill, by quarter.

About these statistics

From April 2018, Landfill Disposals Tax (LDT) replaced Landfill Tax in Wales and is collected and managed by the Welsh Revenue Authority (WRA).

The Landfill Disposals Tax (Wales) Act 2017 gained Royal Assent on 7 September 2017. Like Landfill Tax, LDT is a tax on the disposal of waste to landfill and is charged by weight. It is payable by landfill site operators, who pass on these costs to other waste operators through their gate fee. The tax incentivises the diversion of waste from landfill to other less harmful methods of waste management such as recycling and incineration.

This release includes quarterly estimates based on the latest three-month accounting period for each landfill site operator. Each of those LDT returns is subject to verification as part of mitigation and recovery work that the WRA undertakes routinely and may therefore be revised in future. The following section explains the methods used to derive the statistics from the data supplied in the returns.

All of the data used in this statistical release is available in a spreadsheet on the headline statistics page

Users should refer to the separate glossary and key quality information while reading this statistical release. Relevant terms are defined in the glossary as they are used in the release. The key quality information page describes how Landfill Disposals Tax statistics meet the Code of Practice for Statistics and the dimensions of value, trustworthiness and quality.

Methods used in this release

The majority of landfill site operators have standard accounting periods for reporting to the WRA. These align with the end of our reporting quarters. A small number of landfill site operators use different start and end dates for reporting to the WRA.

Reliefs and discounts

Where waste is referred to as relieved, this will initially have been recorded by the landfill site operators as lower rate waste and then subtracted off in a later part of their return. This release reports the waste subject to reliefs in the relieved or discounted category but not as part of the lower rate category. The weight of any discounted waste due to water discounts is also only included in this relieved or discounted category.

Unauthorised disposals

No data are yet available on unauthorised disposals. We will keep this aspect under review and we may revise the data for this quarter as any unauthorised disposals arise.

Customer insolvency

The LDT system allows for a credit to be made against the tax due for customer insolvency. Previously, a very small amount of credit was claimed by one operator in the reporting quarter July to September 2018. However, this claim has now been rejected by the WRA and tax is now due on this amount. Therefore, a very small revision has now been made to the figures for July to September 2018, which has not affected the rounded amounts presented for tax due presented in this release.

There have been no other instances of this credit being claimed to date. If any credit is claimed in future, it will be subtracted from the total tax due figures shown in this release.

Exempt disposals

Certain disposals of material can be treated as exempt from LDT and therefore are not reported to the WRA. There is no data collected on these exempt disposals.

Table 1a: Weight of waste disposed to landfill [1]

Table 1a shows the weight of waste disposed to landfill, by tax rate and by quarter.

In April to June 2019, there were 292 thousand tonnes of authorised disposals, lower than the same period in 2018. 

The weight of waste disposed in April to June 2019 was lower than the same period in 2018 for each of the three categories shown in Table 1a (standard rate disposals, lower rate disposals and relieved or discounted).

Table 1b: Tax due on waste disposed to landfill [1]

Table 1b shows the tax due on waste disposed to landfill, by tax rate and by quarter.

These disposals for April to June 2019 resulted in £10.4 million of tax due, a fall of 10% from the same period in 2018. This was largely due to a decrease in standard rate disposals by a small number of landfill site operators. 

There may be evidence of a seasonal pattern emerging in the data, with shorter days in winter months potentially a factor. We will investigate this further as we receive more data.

In April to June 2019, the five landfill site operators paying the most tax accounted for 88% of the total tax due. 

The relieved tax amount represents how much tax would have been due had the reliefs not have been applied.

There are 17 authorised landfill site operators covering 23 sites.

Receipts of LDT

Table 2 below shows quarterly receipts received for LDT. This is based on the date the payment was received, sometimes referred to as ‘on a cash basis’. 

Table 2: Landfill Disposals Tax (LDT) paid to the WRA [1]

Table 2 shows the value of Landfill Disposals Tax payments made to the WRA, by quarter.

In April to June 2019, £9.2 million of LDT payments were received by the WRA, lower than in January to March 2019.
