The First Minister is to set out plans to reform council tax in Scotland, including how local authorities can be assigned a share of income tax revenues.

Nicola Sturgeon will reveal her party's proposals for the future of local taxation on a visit to Lasswade High School Centre in Midlothian.

The SNP leader has said the party intends to make local taxes more "progressive" from April 2017 if returned to power in May's Holyrood election.

A report by the cross-party Commission on Local Tax Reform last year called for an end to the council tax and urged politicians to implement a fairer, more progressive and transparent tax to fund local services.

It did not recommend a single alternative but suggested there could be merit in combining a property-based levy with an element of income tax.

A council tax freeze has been in place since the SNP came to power in 2007 and will continue for 2016-17.

Ms Sturgeon is also expected to confirm plans for longer-term changes that will propose incentives for councils to boost economic growth by assigning them a share of income-tax revenues.

Speaking before the event, she said: "Over nine years, the council tax freeze put in place by this government has helped to keep bills affordable during difficult economic times while ensuring councils are properly funded to provide public services.

"When I established the cross-party Commission on Local Tax Reform in 2015, I wanted to ensure that our commitment to fully understand the impact of taxation on Scottish communities was fulfilled.

"Later today, I will outline our proposals for the future of local taxation which build on the findings of the commission's report."

A Scottish Labour spokesman said: "For a decade, the SNP have said they will replace the council tax with something fairer.

"Nicola Sturgeon now has to deliver on her personal promise, otherwise all her talk will be exposed as just posturing."
