THE SINGLE TAX

chaser must also assume. He will then purchase the
land not at $4,000, but at $2,000. The tax charge of
$ 100 and the mortgage interest charge of $100 respec
tively reduce the selling price of land by the same
amount, $2,000. The mortgage and the tax together
therefore reduce it by $4,000; and the purchaser will
buy the land at $2,000, the value of the equity that
remains after both mortgage interest and tax have
been paid. This $2,000 is the capitalisation of the
annual value of the lot after all charges have been met.
The gross value is the taxed value. The net value is
an untaxed value.
It follows from the above too brief analysis that,
under the present system, the selling value of land is an
untaxed value and land owners who invest to-day are
entirely exempt from taxation.
As this exemption of the present owner holds true
to-day, so it will be true in future of each new purchaser
subsequently to the imposition of any new tax. It
is in the very nature of things that the burden of
a land tax cannot be made to survive a change of
ownership.
But when we turn to the case of the taxation of
houses we find that no parallel appears. Whereas a
tax upon the lot could not, in the nature of things,
increase its annual rental, or cost for use, a similar
tax upon the house is added directly to the annual cost
to the user. If a house costing $6,000 to build is
subject to a tax of |ioo, this amount must be paid
annually in addition to an interest charge of $300.
Increasing or decreasing taxation upon the lot has no
influence upon its annual cost to the user; while
increasing or decreasing the tax upon the house
