Report 60% Tax Rate For Almost Top Earners in House prices and the economy Posted May 14, 2014 Nicked from the Telegraph. Doesnt include employee/employer NI. The child benefit taper region looks wrong though. This is an extra 10%. It also doesn't include student loan repayments which add another 9% (?) which can push up EMTR to 80% in some bands. Size of the child benefit taper depends on the number of children. If you had 8 kids the marginal rate would exceed 100%. As tax changes go, a better way to disproportionately target the 'traditional' family would be hard to think up..
