A Conservative MP, who once ran a national chain of estate agents, has written to Boris Johnson urging him to abolish stamp duty and council tax.

Kevin Hollinrake, who is the MP for Thirsk and Malton, urged the Prime Minister to replace the present system of council tax and stamp duty with what he calls a “proportional property tax” at a flat rate of 0.48 per cent annually.

This would be split between national government and the local authority, with 0.32 percent going to the latter.

The tax would be levied on the value of a person’s property each year, with those owning more than one home paying the levy on each property they own.

Deferral options would be available for the elderly and asset rich but cash poor.

He said under the current framework the effective tax rate on residential property in the North East of England was 0.7 per cent, but a mere 0.2 per cent in London, despite property values being higher in the South than the North.

This is because council tax is calculated based on the value of a property decades ago, rather than its value today, so the rise in London and south eastern property prices in recent years has not been reflected.

His plan would also involve taxing land banks owned by developers at the same rate.

Mr Hollinrake’s letter to the Prime Minister was written in conjunction with the campaign group Fairer Share, which did the policy research for the proposal.

It calculated that, if levied at 0.48 per cent of estimated property value, approximately 18m households in England would see a reduction in their tax bills.

Despite this, the proposal would be revenue neutral, it would not cost the government money, nor would it generate extra revenue.

Mr Hollinrake’s letter asks for a meeting with Mr Johnson to discuss his plans in more detail.

Prior to his election as an MP in 2015, Mr Hollinrake co-founded, and later floated on the stock market, the Hunter’s chain of estate agents.
