This article analyzes a specific municipal tax credit program that has been adopted by the city ofWinnipeg, Manitoba, Canada. The program allows 50% of the net private investment in eligible conservation work on a historic building to be designated as a nonrefundable tax credit against future municipal tax liabilities (property, business, amusement) on the structure and land on which it is situated. In the article, the authors show how an investor's expected tax liability affects the amount of expenditure undertaken. Specifically, the proposal introduces a nonlinear subsidy schedule that limits the total amount an investor's tax liability can be reduced. The authors conclude that the program is quite general and can be used by local governments to encourage spending in other areas, for example, energy conservation or general housing renewal.
