I'm going to say kinda...
I think it should be a more sensible increases, so currently the income tax rates are:
11,500 0%
11,501-45,000 20%
45,001 -150,000 40%
150,001+ 45%
I think the rates should be:
11,500 0%
11,501-45,000 20%
45,001-150,000 30%
150,001 - 500,000 40%
500,001+ 45%
This is because if you're on a 44,000 wage and get a pay rise to 45,000, you get pushed up to the next tax bracket... As you guess it, you're earning less money than before your rise because of the tax bracket. Personally I think this is unfair as getting a pay rise around this amount usually means you're in a skilled job (lab tech for example) and the Gov are pretty much punishing you for your job
A steady increase in the tax bracket would reduce the risk of payed more but earned less
But then again, I also think what would help the economy more would be reducing the VAT rate back to 17.5 or even 15% but thats not gunna happen
