私人企业（包括政府雇佣）退休金要在居住国交税，国家退休金在颁发国家交税。

ARTICLE 17 Pensions and Annuities

This article deals with the taxation of private pensions and social security benefits. Pensions in consideration of government employment are covered under Article 18. Paragraph 1 provides that pensions in respect of private employment derived by a resident of a Contracting State （绿卡持有者的居住国）may be taxed only in that State（同上，绿卡持有者的居住国） On the other hand, public payments, such as social security benefits or public welfare payments, paid by a Contracting State may be taxed only in the paying State （付公共安保退休金的国家自己收税）. This provision is excepted from the “saving” clause of paragraph 2 of the Protocol, so the United States will not tax its residents on social security benefits paid to them by the People's Republic of China.
