Most of the things government provide (like infrastructure) are built to accommodate a certain number of people. The costs of these things don't decrease as population shrinks. So logically the tax burden will be high per capita as it gets spread across less people and cannot realistically be shrunk (because infrastructure maintenance still costs the same even if less people use it).
