Rising Landfill Taxes Fueling Fly-Tipping Epidemic, Report Claims
A UK think-tank argues that increased landfill levies have backfired, leading to a surge in illegal waste dumping and a significant loss of tax revenue.
Soaring landfill taxes in the UK are directly contributing to a record surge in fly-tipping, according to a report by the Institute for Economic Affairs (IEA). The think-tank found that while landfill levies have increased dramatically, actual revenues have declined in real terms.
Landfill taxes have risen from £7 per tonne in 1996 to £126.15 in 2025. Despite this steep increase, the IEA reports that revenues have roughly halved in real terms. Fly-tipping incidents in England have consequently risen by 31 percent since the 2018/19 period, reaching a new high of 1.26 million cases in 2024/25. The IEA suggests that taxing the waste sector more heavily has proven counterproductive.
Her Majesty's Revenue and Customs (HMRC) estimates that the discrepancy between expected landfill tax revenues and actual receipts reached £240 million in 2024/25. The report highlighted a specific instance in Oxfordshire where approximately 21,000 tonnes of waste were dumped in a field, with an estimated cleanup cost of £7.3 million.
Beyond landfill taxes, the report also points to high duties on tobacco as a factor fueling a booming black market. Nearly one in three cigarettes smoked in Britain are now believed to be illegal, with declining tax revenues from the sector. While a portion of this decline is attributed to a 20 percent drop in adult smokers between 2021 and 2024, legal cigarette sales have fallen by 46 percent in the same timeframe. The number of smokers purchasing black market tobacco reportedly doubled between 2023 and 2025, with counterfeit cigarettes making up 32.3 percent of the total market.
Similar trends are observed in alcohol duties. Predictions for the 2024/5 financial year anticipated £14.2 billion in alcohol duty revenue, but actual receipts fell to £12.4 billion in 2025/6. The IEA calculated that the combined revenue from alcohol, tobacco, and landfill duties fell £5.2 billion short of Office for Budget Responsibility (OBR) forecasts for 2024/5. This is a significant decrease from 2021/2, when these duties generated £3.2 billion more.
Christopher Snowdon, head of lifestyle economics at the IEA and author of the report, stated that there is a point at which increasing taxes ceases to be effective. He argued that excessive taxes not only result in billions in lost Treasury revenue but also create lucrative opportunities for criminals and incentivize illegal waste disposal. Snowdon advised the government to consider that continuously raising tax rates does not automatically guarantee increased revenue, noting that, as acknowledged by the OBR regarding cigarette duty, some taxes have already been pushed beyond their optimal level.
In response to the rising problem, local authorities were granted new powers earlier this year to impose penalties of up to £5,000 on individuals caught fly-tipping.
