Hi Dan - are figures available for the top 0.1%? Or for the top 0.01%? That graph doesn’t look the most convincing and I’ve heard other evidence elsewhere. Agreed that the effective rate is higher now. The people who genuinely paid much 83% tax must have been financially naive.
Anyone on £180k income today just pops £60k tax free into a SIPP (which can grow at 10%) and legally declare only £120k income. And that’s all probably from rental income or other investments. You don’t have to do any work to have that level of income. Just own enough assets tax free from daddy.
