What is the primary purpose of donor's tax?

The primary purpose of donor's tax is to tax the transfer of assets by gift while the donor is alive. This tax is levied on the value of gifts given, which reflects the idea that wealth transfers can occur through gifting rather than only through inheritance upon death. It serves to regulate and tax the act of giving, ensuring that the government collects revenue from significant transfers of wealth made during a person’s lifetime, thereby addressing concerns of wealth inequality and tax avoidance strategies that might arise if people were to only transfer wealth through bequests after death.

The other options do not accurately capture the essence of donor's tax. For instance, while enhancing government income could be a result of taxation, it is not the primary purpose behind the specific imposition of a donor's tax. Similarly, taxing inheritance received by heirs is related to estate taxes rather than donor's tax. Finally, providing financial aid for education is a separate issue and not related to the purpose of taxing gifts.
