In general. Any person required to furnish a bond under the provisions of the Code (other than section 6803(a)(1), relating to bonds required of certain postmasters before June 6, 1972, and section 7485, relating to bonds to stay assessment and collection of a deficiency pending review of a Tax Court decision), or under any rules or regulations prescribed under the Code, shall (except as provided in paragraph (d) of this section) execute such bond—

On the appropriate form prescribed by the Internal Revenue Service (which may be obtained from the district director), and

With satisfactory surety.

Satisfactory surety—(1) Approved surety company or bonds or notes of the United States. For purposes of paragraph (a) of this section, a bond shall be considered executed with satisfactory surety if:

It is executed by a surety company holding a certificate of authority from the Secretary as an acceptable surety on Federal bonds; or

It is secured by bonds or notes of the United States as provided in 6 U.S.C. 15 (see 31 CFR part 225).

Other surety acceptable in discretion of district director. Unless otherwise expressly provided in the Code, or the regulations thereunder, a bond may, in the discretion of the district director, be considered executed with satisfactory surety if, in lieu of being executed or secured as provided in subparagraph (1) of this paragraph (b), it is:

Executed by a corporate surety (other than a surety company) provided such corporate surety establishes that it is within its corporate powers to act as surety for another corporation or an individual;

Executed by two or more individual sureties, provided such individual sureties meet the conditions contained in subparagraph (3) of this paragraph (b);

Secured by a mortgage on real or personal property;

Secured by a certified, cashier's, or treasurer's check drawn on any bank or trust company incorporated under the laws of the United States or any State, Territory, or possession of the United States, or by a U.S. postal, bank, express or telegraph money order;

Secured by corporate bonds or stocks, or by bonds issued by a State or political subdivision thereof, of recognized stability; or

Secured by any other acceptable collateral. Collateral shall be deposited with the district director or, in his discretion, with a responsible financial institution acting as escrow agent.

Conditions to be met by individual sureties. If a bond is executed by two or more individual sureties, the following conditions must be met by each such individual surety:

He must reside within the State in which the principal place of business or legal residence of the primary obligor is located;

He must have property subject to execution of a current market value, above all encumbrances, equal to at least the penalty of the bond;

All real property which he offers as security must be located in the State in which the principal place of business or legal residence of the primary obligor is located;

He must agree not to mortgage, or otherwise encumber, any property offered as security while the bond continues in effect without first securing the permission of the district director; and

He must file with the bond, and annually thereafter so long as the bond continues in effect, an affidavit as to the adequacy of his security, executed on the appropriate form furnished by the district director.

Adequacy of surety. No surety or security shall be accepted if it does not adequately protect the interest of the United States.

Bonds required by Internal Revenue Code of 1939. This section shall also apply in the case of bonds required under the Internal Revenue Code of 1939 (other than sections 1423(b) and 1145) or under the regulations under such Code.
