There is no sense in frantically racing to charge as little tax as possible. That is not a viable solution unless you really want to see what budget cuts look like.
lowering tax rates while simplifying tax code to reduce/remove loopholes would, in theory, increase revenue. in an ideal world, simpler tax code would reduce the need for accountants as well, further reducing costs.
I'm not sure that "simplifying tax code" and "reduce/remove loopholes" go together, do they? The simpler the language, the more "wiggle room" there usually is. If you want to reduce/remove loopholes, you're going to definitely be complicating the tax code else you leave too much room for interpretation mistakes.
