You still don't understand... currently it's 25% emergency tax + 12% NI...25%(I think that's the amount) is emergency tax, which is far too much for low earners. What I'm saying is that when you get emergency taxed at 25%, for a short amount of time, that's too much, so 30% all the time would be silly. Low earners do not normally get 25%. If I'm wrong, let me know, I'm no tax expert.
The proposed is 30% tax 0% NI...
