We don't know how lucky we are: tax edition

The second installment of my piece on The Outside of the Asylum is up at The Spinoff. It covers tax and airport security. A snippet:

America’s patchwork of state-level sales taxes are even worse. Every state can apply its own unique taxes. This is not limited just to deciding the rate of taxes, but also the definitions of what is and is not taxable. Some states apply sales taxes to candy but not to other foods, and different states have different definitions of what counts as candy. Wisconsin’s Department of Revenue even issued a 1,437-word memo explaining which types of ice-cream cakes, or slices thereof, are taxable or untaxed

The mess is just as bad at the federal level, where free tans at video-rental stores are taxable but not tans provided as part of a health club membership. A simple enough (albeit ludicrous) 10% tax on tanning services proved anything but.

The economic consequences of a system riddled with bread-deciders and jam-deciders and ice-cream deciders and tan-deciders can be staggering. Taxes become far less efficient not only because of the holes riddled throughout the system, but also the legal costs of producers trying to convince courts that their product is exempt rather than taxable.

When there are experts aplenty whose livelihood depends on complicated, messy and incomprehensible tax systems, with large penalties for anyone getting things wrong, it is difficult to make the tax system less complicated, messy, incomprehensible and punitive.

New Zealand’s GST is uniquely, and admirably, clean. It applies broadly. Every producer has an incentive to report honestly because they also report the GST they paid to their suppliers on every item when claiming GST on their inputs.

Were New Zealand to exempt healthy foods from GST, we would well be on the slippery slope. It is one of those things that sounds really easy, but would be an utter disaster in practice

What counts as healthy? Not only does the medical evidence keep changing, but there would also be a string of boundary cases needing adjudication. If beans are healthy, what about frozen beans? Beans in a can? Beans in a can with pork fat and sauce? How much pork fat and sauce before it is taxable? What if we use Jamie Oliver’s recipe and fly him in to say it’s good?

Even worse, think through the consequences of tax exemption.

The Spinoff also runs comments sections on their serialisation on Facebook. I'm not on the Book of Faces, but had a gander using the Initiative's account. If you're on the Book of Faces and are interested in such things, their thread on the first installment (published Saturday) is here; thread on the second is here.
