Welfare Work and Kids Update
I've had an interesting E-mail correspondence with Phil Sage over the original post (below) and the Universal Marginal rates (or Basic income) system I alluded to. It transpires that here may be an error in the specific proposal I drew up (see sidebar link for pdf document) - fortunately in the right direction.
I estimated the total tax base from a treasury table which I assumed showed the taxbase for all income taxpayers (including companies). It now appears that the table may have shown the taxbase for individuals only. If this is true it would be possible to have more generous benefits and lower tax rates than I suggested.
I have EMailed Treasury for confirmation and will do a revised and updated version of the document when I hear back.
Watch this space.
