Landfill Disposals Tax (LDT) is a tax on the disposal of waste to landfill, charged by weight.
There are 3 rates of LDT:
- lower rate for materials which meet the conditions set out in the Landfill Disposals Tax (Wales) Act 2017
- standard rate for all other material
- unauthorised disposals rate for taxable disposals made at places other than authorised landfill sites
| Standard rate | Lower rate | Unauthorised disposals rate | |
|---|---|---|---|
| 2025 to 2026 | £126.15 | £6.30 | £189.25 |
| 2024 to 2025 | £103.70 | £3.30 | £155.55 |
| 2023 to 2024 | £102.10 | £3.25 | £153.15 |
| 2022 to 2023 | £98.60 | £3.15 | £147.90 |
| 2021 to 2022 | £96.70 | £3.10 | £145.05 |
| 2020 to 2021 | £94.15 | £3.00 | £141.20 |
| 2019 to 2020 | £91.35 | £2.90 | £137.00 |
| 2018 to 2019 | £88.95 | £2.80 | £133.45 |
The unauthorised rate is set at 150% of the standard rate. This creates an additional financial deterrent for people seeking to dispose of waste illegally.
