The Window Tax - a tax on light and air
What was the The Window Tax?: It was a banded tax. For instance, in 1747 for a house with ten to fourteen windows, the tax stood at 6d. per window, fifteen to nineteen windows, 9d., and exceeding twenty or more, 1s.. The tax was raised six times between 1747 and 1808. By then the lowest band started at six windows. This was raised in 1825 to eight windows.
