"The effect of freezing mileage rates lowers real wages after tax. This might have the unintended benefit of moving more trips to public transport, reducing congestion, pollution, and carbon emissions. But it's also going to reduce the number of people willing to do jobs that require a lot of driving, and many of those are frontline workers we all depend on. Ideally, this might be an opportunity to re-examine tax deductions for mileage more broadly - possibly even leaving those lower so that the costs of using a car are more visible, but making this up with higher standard deductions or wage increases."

"Tax nerds were promised a mega "tax day" today, with a number of tax consultations being published together. In principle this looked like a fantastic move. Instead we got a snooze-fest, even by tax standards." Dr Arun Advani, Assistant Professor of Economics and Impact Director, CAGE, reacts to "tax day." 

As HMRC reports that the tax gap, the difference between the tax owed and what is actually paid, has fallen to the lowest recorded rate, Dr Arun Advani from the Department of Economics comments that there is still work to do on reducing that gap - particularly as the UK leaves the European Union.
