###### Sections 18 to 20 – Calculation of taxable weight of material, Calculation of taxable weight of material by operator and Determination of weight of material by operator

40.LDT is charged on a taxable disposal by multiplying the taxable weight of the material by the tax rate applicable, as set out at section 14. Therefore an accurate calculation of the taxable weight of the material being disposed of is important.

41.Section 18 provides that the taxable weight of the material in a taxable disposal (made at an authorised landfill site) must be calculated by the landfill site operator and may be calculated by WRA if it thinks it appropriate to do so. This section also specifies the taxable weight that applies for the purposes of section 14(2) and (5) of the Act.

42.Section 19 sets out how an operator must calculate the taxable weight of the material in a taxable disposal. The landfill site operator must determine the weight of the material in tonnes in accordance with section 20. Where a landfill site operator has approval to apply a discount in respect of water present in material, the landfill site operator may apply the discount (or a lesser discount) to the weight determined, subject to the conditions of the approval (if any).

43.Section 20 requires the landfill site operator to determine the weight of the material in a taxable disposal by using a weighbridge. For this purpose, the landfill site operator must ensure that the material is weighed on the weighbridge before the disposal is made, and that the weighbridge meets the requirements set out in applicable weights and measures legislation.

44.There may however be circumstances where it is not possible for a landfill site operator to use a weighbridge. For example, a landfill site may not have a weighbridge or a weighbridge may have broken down. Section 20(3) therefore makes provision for a landfill site operator to make an application to WRA for approval to use an alternative method to determine the weight of material in a taxable disposal. For example, an alternative method may include a calculation based on the maximum permitted weight of a container.

45.Section 20 also makes provision for WRA to specify the manner in which an application for an alternative method is to be made and the information it must contain. This section makes further provision about the powers of WRA in relation to an approval for an alternative method. For example, WRA may give approval in relation to all taxable disposals or to particular descriptions of taxable disposals. WRA may give approval unconditionally or subject to conditions. Further, WRA may vary or revoke an agreement; this may occur if WRA consider the alternative method is not giving an accurate indication of the weight or is not being fully observed and there is a risk to the tax revenue.

46.There is a penalty for failing to determine the weight of the material in a taxable disposal in accordance with section 20. This is set out in section 61 of the Act.
