Jaunzeme is currently employed at the Ministry of Economics and formerly worked at the Ministry of Welfare, LTV reported.
A press conference later in the day is scheduled to give further details of Jaunzeme's plans for VID, which has always been an institution wracked by controversy.
As previously reported by LSM, a previous competition earlier this year came up with a new head of VID who promptly resigned before taking up his post.
That contest in turn had been prompted by the sudden death of his predecessor. Before that, a previous tax chief had announced an ambitious reform plan for the organization - and also resigned soon afterwards citing the futility of trying to change it.
Various other controversies have also beset VID, and yet according to recent research Latvia's tax system rates as one of the top 20 in the world.
