The magical shrinking sums of the ‘windfall tax’12 Dec 2025 00:00
Counterproductive tax changes are shaping up to be this government’s forte. Want more houses built? Why not jack up stamp duty, especially for first-time buyers. More investment in pensions? How about doing over salary sacrifice schemes. Growth? What better than landing business with £25 billion a year of extra payroll costs.
Still, even by Labour’s usual standards, the energy profits levy (EPL) on North Sea oil and gas is a corker. What’s the point of a tax that’s doomed to raise pretty much no money at all? Worse, one whose very existence hammers jobs and investment, so also cutting personal and corporation tax receipts too?
As Brian Gilvary, the Ineos Energy chairman, wrote in The Times this week: “The EPL, introduced in response to a temporary post-Covid oil price spike, is now undermining the revenue it was meant to raise.” Sure, he is talking his book. But he’s right.
The levy, brought in under the Tories in 2022 and extended under Labour, has resulted in North Sea groups paying a headline tax rate of 78 per cent. Designed as a windfall tax, it’s produced ever-declining sums to the taxpayer. First, because oil and gas prices have dropped since the jump that followed Russia’s assault on Ukraine. Second, because, in response to the levy, companies have cut jobs and investment.
The Aberdeen & Grampian Chamber of Commerce is the latest to make that point, noting the levy “has been blamed for thousands of redundancies, including 700 at Harbour Energy” and 800-plus at the big infrastructure hubs at Grangemouth and Mossmorran.
The upshot? Tax receipts from North Sea oil and gas production are down from £9 billion in 2022-23 to £4.5 billion in 2024-25, with the Office for Budget Responsibility forecasting just £300 million by 2030-31. One other reason for the drop, cited by the OBR? The levy pushing tax-paying companies into mergers with those “with a large stock of tax losses”, so enabling the combo to offset taxable profits.
Hence, the calls from the Aberdeen and British Chambers of Commerce, via a letter signed by 7,000 companies, business leaders and workers, for the government to bring forward its replacement for the EPL. It’s proposed a new oil and gas price mechanism (OGPM) from 2030 that will apply only when oil prices exceed an index-linked $90 a barrel and gas 90p per therm — much more like windfall territory than the EPL triggers of $74 and 54p. Only if prices stay below those levels for two successive quarters is the levy disapplied.
Maybe that’ll happen: oil’s around $61, though gas futures point to about 71p this quarter. But, if not, in the years waiting for the OGPM, more jobs — and tax receipts — will go. As the letter puts it, the government faces a “clear choice”: keep the EPL in place and see “thousands” more “avoidable North Sea job losses” or bring forward the OGPM and “unlock investment” — up to £50 billion on the maths of the lobby group Offshore Energies UK
