Here's my understanding of the situation:
The 'wicked' churches each prepare statutory accounts which show values of their properties, as well as properly record income and expenditure. despite what the WTS claims, churches do pay tax - some income is subject to GST for example, and from what I've seen at closehand, it's required to allow no subterfuge or tax avoidance.
One denomination I'm familiar with, the Anglican Church has a company, the Anglican Church Property Trust, that holds title to all properties. However, the valuations are included in each church's (parish's) statutory accounts.
Compare that with JWs and their WTS in Australia where congregations do not, as you know, prepare statutory accounts and certainly never submit themselves, nor even register, for GST. Thus, although there is a company holding title to KH properties, they have managed to position themselves to avoid making public the extent of their real estate holdings. There certainly isn't transparency.
So much for their empty boast about respecting the "superior authorities".
