A landfill tax or levy is a form of tax that is applied in some countries to increase the cost of landfill. The tax is typically levied in units of currency per unit of weight or volume (£/t, €/t, $/yard³). The tax is in addition to the overall cost of landfill and forms a proportion of the gate fee.
A tax or fee may be imposed on landfills or other disposal facilities as a means of raising general revenues, to generate funds for inspection programs or long-term mitigation of environmental impacts related to disposal, or as a means of inhibiting disposal by raising the cost in comparison to preferable alternatives, in the same manner as an excise or "sin tax".
Landfilling is discouraged due to a number of key reasons:
In New Zealand the Waste Minimisation Act 2008 allowed for the charging of a landfill levy. Half of the landfill levy goes to local authorities with the other half going into a Waste Minimisation Fund. As of 2010 it is set at $10 a tonne but it can be reviewed by the Minister for the Environment.
The UK Landfill Tax was introduced in 1996 by Conservative Secretary of State for the Environment, John Gummer, and was the UK's first environmental tax. The tax is seen as a key mechanism in enabling the UK to meet its targets set out in the Landfill Directive for the landfilling of biodegradable waste. Through increasing the cost of landfill, other advanced waste treatment technologies with higher gate fees are made to become more financially attractive.
The amount of tax levied is calculated according to the weight of the material disposed of and whether it is active or inactive waste.
Inevitably there will be some mixing of waste such as inert bricks and concrete mixed with small amounts of wood or mineral dust packaged in polythene bags. It is for the producer of the waste to decide what is reasonable and acceptable in terms of active waste contamination of inert waste.
The landfill site operator is responsible for paying landfill tax. However, operators will pass the cost on to businesses and local councils on top of normal landfill fees. VAT is charged on the landfill fees and the landfill tax.
