Council tax in Scotland should be increased to the same levels as the rest of the UK, a think-tank has argued today.

A briefing from IPPR Scotland said that closing the tax gap in council tax revenues between Scotland and the rest of the UK would generate up to £900m a year in extra revenue.

The briefing outlined five proposals for reforming council tax, including implementing higher increases on bills for properties in higher bands throughout the next parliament.

It also called on the Scottish Government to extend the council tax reduction scheme and work with councils to develop new local taxes.

In a blog, director of IPPR Scotland, Russell Gunson, wrote: 'Council tax is incredibly overdue reform.

'It's outdated, based on values from 30 years ago.

'It's regressive by value, in that the highest value properties have the lowest bills as a percentage, and it's regressive by income, with lower income families paying more council tax as a proportion of their income than the richest.

'Council tax doesn't raise enough money.

'If Scotland's council tax bills were on average the same level as Wales we would have around £600m more to spend each year.

'If bills were the same on average as in England we'd have around £900m more to spend each year.'
