Perhaps the most seductive argument of the flat-taxers is the argument from the perspective of simplicity. Unfortunately you are delusional if you believe it would be all that simple. We would still need a complex process to determine what our net, taxable income might be. Those of you who are self-employed, for example, would still have to figure out your expenses and net incomes. We would still need a complicated regime for taxing foreign income earned by domestic enterprises, and the list goes on and on. I don't know of a single credible expert who believes a flat tax system would be much simpler at all.
But let's assume for the sake of argument (and in the face of common sense to the contrary) that it would be simpler. I would suggest there are worse things in the world than complexity. And one of them is paying higher taxes. In short, what most flat-tax proponents don’t seem to understand are some of the reasons for all the tax complexity. The reason is that many people are willing to wade through a great deal of complexity in order to lower their tax burden. So that, in a sense, given the tax system, much of the complexity that everyone denounces is voluntary. In fact, if we desire simplicity, we can achieve it right now, and without the flat tax. We could just eliminate all deductions, full stop. I can assure you that that is an outcome that most would not like (how many of my US friends out there take a deduction for their mortgage interest?)
And I don't fathom your animosity for tax lawyers and accountants. Denouncing tax lawyers and accountants is like blaming doctors for the existence of disease. The fact is that we live in societies led by governments whose main objective in life seems to be to encroach on our economic liberty through an extortionary tax system. I wish tax rates were far lower and that government was far less intrusive in my economic sphere, but until that occurs, my complaint is not with tax lawyers and accountants, but with the high tax system that makes them necessary to protect me from out of control governments who can't control their spending. So long as that system exists (and I don't believe a flat tax would be any different), we must realize that they are our last defence against the continuing encroachment of the state into our economic lives. Tax lawyers are heroes. And some of them are even pipe smokers.
