The Scottish Government last year re-acquired the right to vary income tax
The previous +/-3p in the £ right was allowed to lapse when iirc the HMRC upgraded its systems/after 10 years of Labour/LibDem coalition. Iirc, the original legislation had also been written badly so that any change had to be the same on all rates of income tax, so it would be have been very regressive, with no ability to change the thresholds plus there was a threat? belief that any extra income that the Scottish Government gathered in, would have been taken off our allowance funding from WM. So Scots would've ended paying more in taxes, but still not have any extra to fund what we believed to be important.
John Swinney, when he was Finance Minister, managed to finally get that budget loophole closed to guarantee that extra funds raised would not be counterbalanced by reduced Barnet formula.
So when the new Scottish income tax regime came in, under which higher rate earners do pay a bit extra but lower earners pay less, the BBC did "Vox pox" to get comments. They obviously worked really hard to find anyone to criticise it, as the "worst" they could find was someone who said, "I'd rather not have to pay extra and I want to see it used well, but the people who work for me are paying less and that's a good thing". 
Unfortunately, it's just tinkering at the edges, as corporate tax, tax loopholes, excise duty and VAT are all still retained powers. 
What gets me about austerity apologists supporters is that they seemingly are quite happy in their hypocritical belief that the super rich need more money to motivate themselves to "do more" while the poor need to be made poorer in order to motivate them because apparently they enjoy having to go to Food Banks
