My marginal tax rate

For every £100 + VAT my employer invoices clients for work I have done, they pay me about £40 gross.

This nets down to £23 after income tax and NIC at my marginal rate (the overall average is a bit lower than that).

My wife decides how I spend two-thirds of my income. This is mainly private school fees for her social status reasons, officially known as "I just want what's best for the children", but either way it is rent, ransom or tax.

This leaves yours truly with £8 pocket money to spend on the finer things in life, out of the £120 that the client originaly paid, a marginal tax rate of 93% or so.
