The land value increment tax shall be exempted when the land is compulsorily purchased.The exemption of land value increment tax as provided by the preceding Paragraph shall, mutatis mutandis, apply to the land reserved for the public infrastructure designated according to the Urban Planning Law. But if it is transferred after being re-designated as non-public infrastructure land, “the value of land originally assessed” or “the value of land at the penultimate transfer” before the initial exemption of the land value increment tax shall be deemed as its “original value of land” for the calculation of its land value increments for the imposition of the land value increment tax.The provisions of Paragraph 1 shall, mutatis mutandis, apply to any private land which may be compulsorily purchased according to law, when its landowner is willing to sell the land, by compensation for compulsory purchase to the competent authorities.For the readjustment land, the land value increment tax shall be decreased by 40 per cent if the land ownership is transferred for the first time after readjustment.
