This week, Neil Insull and Matt Crawford look at the IFS Green Budget and its warning to Rachel Reeves to avoid “half-baked” tax fixes ahead of the next Budget. They discuss what this could mean for future policy and the pressures facing the Chancellor.

They also cover a rare court ruling allowing a judicial review against HMRC five years late, and the Treasury’s plans to tighten the sugar tax,  a move that could see drinks like Ribena and Lucozade changing their recipes once again. And in a final twist, they look at a VAT dispute involving laughing gas that proves there’s nothing funny about tax classification.
