(a) Sections 1.900 through 1.953, to the extent they reflect remedies or procedures prescribed by the Debt Collection Act of 1982 and the Debt Collection Improvement Act of 1996, such as administrative offset, use of credit bureaus, contracting for collection agencies, and interest and related charges, do not apply to debts arising under, or payments made under, the Internal Revenue Code of 1986, as amended (26 U.S.C. 1 et seq.); the Social Security Act (42 U.S.C. 301 et seq.), except to the extent provided under 42 U.S.C. 404 and 31 U.S.C. 3716(c); or the tariff laws of the United States. These remedies and procedures, however, may be authorized with respect to debts that are exempt from the Debt Collection Act of 1982 and the DCIA of 1996, to the extent that they are authorized under some other statute or the common law.

(b) This section should not be construed as prohibiting the use of §§ 1.900 through 1.953 when collecting debts owed by persons employed by agencies administering the laws cited in paragraph (a) of this section unless the debt arose under those laws.
