Scotland should control two-fifths of its own revenues with the power to raise taxes on the rich, according to Labour.
The party has unveiled the long-awaited findings of its Devolution Commission in Edinburgh.
The Scottish Parliament should raise around 40% of its own revenues, around £2 billion more than the most recent Scotland Act.
The Scotland Act will give Holyrood control over more tax raising powers in exchange for a 10p in the pound cut in the block grant, but Labour believes this should be extended to 15p - giving Scotland control of three quarters of the basic rate of income tax.
The leader of the Better Together campaign and former Labour Chancellor Alistair Darling said he was offering a "positive vision" for staying the UK.
On the day of the six-month countdown to the referendum, Mr Darling added that independence would bring "huge risks".
The Scottish Deputy First Minister Nicola Sturgeon has set out what she claims are six "compelling reasons" in favour of independence to mark the milestone that it's six months to the Scottish Referendum.
She argues an independent Scotland would create more jobs, spend tax revenues on "Scotland's priorities", protect public services, "guarantee we get governments we vote for", set up an oil fund and have a retirement age in line with Scotland's circumstances.
People in the Scottish Borders and Dumfries and Galloway will join fellow Scots in six months time to vote in the Scottish Independence Referendum.

Deputy Minister Nicola Sturgeon joined Alex Salmond on stage to launch the SNP's White Paper.
She envisages 24th March 2016 as the date, should Scotland vote yes, for the country to become an independent country.
Sturgeon's particular focus within this white paper addresses the topics of women and child, the bedroom tax and welfare reform, and pensions.
The SNP has set out shop with a proposal that Scotland become independent, it intends to provide free child care for all pre-school children.
This is a policy, they say, that is dual purpose; good for the youngest children and their parents.
It would also mean that by supporting more women to go into the workplace, it would generate more tax revenues.
The Scottish government says it will give pensioners £160 a week from 2016 if independence goes ahead.
The SNP published a pensions paper today, outlining their plans.
The figure for new pensioners would at least match any by the UK government and the paper also suggests that Scotland may not raise the pension age to 67.
The UK government plans to do so by 2026.
