According to China's land value-added tax law, there are two situations in which the projects developed by real estate enterprises need to be liquidated, one is when the tax law stipulates that the projects need to be liquidated, and the other is when the tax authorities notify enterprises to liquidate the projects according to the tax law. In other words, in the first case, the taxpayer must fulfill the tax liquidation declaration procedures by himself. In the second case, the enterprise can't start the land value-added tax liquidation by itself, and it needs to receive the notice from the tax authorities before it can perform the liquidation declaration procedure. If no notice is received from the tax authorities, the enterprise does not need to carry out land value-added tax liquidation.
