                       TITLE 26--INTERNAL REVENUE
 
    CHAPTER I--INTERNAL REVENUE SERVICE, DEPARTMENT OF THE TREASURY 
                               (CONTINUED)
 
PART 601_STATEMENT OF PROCEDURAL RULES--Table of Contents
 
             Subpart E_Conference and Practice Requirements
 
Sec. 601.506  Notices to be given to recognized representative; direct 

contact with taxpayer; delivery of a check drawn on the United States 
Treasury to recognized representative.

    (a) General. Any notice or other written communication (or a copy 
thereof) required or permitted to be given to a taxpayer in any matter 
before the Internal Revenue Service must be given to the taxpayer and, 
unless restricted by the taxpayer, to the representative according to 
the following procedures--
    (1) If the taxpayer designates more than one recognized 
representative to receive notices and other written communications, it 
will be the practice of the Internal Revenue Service to give copies of 
such to two (but not more than two) individuals so designated.
    (2) In a case in which the taxpayer does not designate which 
recognized representative is to receive notices, it will be the practice 
of the Internal Revenue Service to give notices and other communications 
to the first recognized representative appointed on the power of 
attorney.
    (3) Failure to give notice or other written communication to the 
recognized representative of a taxpayer will not affect the validity of 
any notice or other written communication delivered to a taxpayer.

Unless otherwise indicated in the document, a power of attorney other 
than form 2848 will be presumed to grant the authority to receive 
notices or other written communication (or a copy thereof) required or 
permitted to be given to a taxpayer in any matter(s) before the Internal 
Revenue Service to which the power of attorney pertains.
    (b) Cases where taxpayer may be contacted directly. Where a 
recognized representative has unreasonably delayed or hindered an 
examination, collection or investigation by failing to furnish, after 
repeated request, nonprivileged information necessary to the 
examination, collection or investigation, the Internal Revenue Service 
employee conducting the examination, collection or investigation may 
request the permission of his/her immediate supervisor to contact the 
taxpayer directly for such information.

[[Page 106]]

    (1) Procedure. If such permission is granted, the case file will be 
documented with sufficient facts to show how the examination, collection 
or investigation was being delayed or hindered. Written notice of such 
permission, briefly stating the reason why it was granted, will be given 
to both the recognized representative and the taxpayer together with a 
request of the taxpayer to supply such nonprivileged information. (See 
7521(c) of the Internal Revenue Code and the regulations thereunder.)
    (2) Effect of direct notification. Permission to by-pass a 
recognized representative and contact a taxpayer directly does not 
automatically disqualify an individual to act as the recognized 
representative of a taxpayer in a matter. However, such information may 
be referred to the Director of Practice for possible disciplinary 
proceedings under Circular No. 230, 31 CFR part 10.
    (c) Delivery of a check drawn on the United States Treasury--(1) 
General. A check drawn on the United States Treasury (e.g., a check in 
payment of refund of internal revenue taxes, penalties, or interest, see 
Sec. 601.504(a)(5)) will be mailed to the recognized representative of 
a taxpayer provided that a power of attorney is filed containing 
specific authorization for this to be done.
    (2) Address of recognized representative. The check will be mailed 
to the address of the recognized representative listed on the power of 
attorney unless such recognized representative notifies the Internal 
Revenue Service in writing that his/her mailing address has been 
changed.
    (3) Authorization of more than one recognized representative. In the 
event a power of attorney authorizes more than one recognized 
representative to receive a check on the taxpayer's behalf, and such 
representatives have different addresses, the Internal Revenue Service 
will mail the check diretly to the taxpayer, unless a statement (signed 
by all of the recognized representatives so authorized) is submitted 
which indicates the address to which the check is to be mailed.
    (4) Cases in litigation. The provisions of Sec. 601.506(c) 
concerning the issuance of a tax refund do not apply to the issuance of 
a check in payment of claims which have been either reduced to judgment 
or settled in the course (or as a result) of litigation.
    (d) Centralized Authorization File (CAF) system--(1) Information 
recorded onto the CAF system. Information from both powers of attorney 
and tax information authorizations is recorded onto the CAF system. Such 
information enables Internal Revenue Service personnel who do not have 
access to the actual power of attorney or tax information authorizations 
to--
    (i) Determine whether a recognized representative or an appointee is 
authorized by a taxpayer to receive and/or inspect confidential tax 
information;
    (ii) Determine, in the case of a recognized representative, whether 
that representative is authorized to perform the acts set forth in Sec. 
601,504(a); and
    (iii) Send copies of computer generated notices and communications 
to an appointee or recognized representative so authorized by the 
taxpayer.
    (2) CAF number. A Centralized Authorization File (CAF) number 
generally will be issued to--
    (i) A recognized representative who files a power of attorney and a 
written declaration of representative; or
    (ii) An appointee authorized under a tax information authorization.

The issuance of a CAF number does not indicate that a person is either 
recognized or authorized to practice before the Internal Revenue 
Service. Such determination is made under the provisions of Circular No. 
230, 31 CFR part 10. The purpose of the CAF number is to facilitate the 
processing of a power of attorney or a tax information authorization 
submitted by a recognized representative or an appointee. A recognized 
representative or an appointee should include the same CAF number on 
every power of attorney or tax information authorization filed. However, 
because the CAF number is not a substantive requirement (i.e., as listed 
in Sec. 601.503(a)), a tax information authorization or power of 
attorney which does not include such number will not be rejected based 
on the absence of a CAF number.

    (3) Tax matters recorded on CAF. Although a power of attorney or tax 
information authorization may be filed in all matters under the 
jurisdiction of the Internal Revenue Service, only those documents which 
meet each of the following criteria will be recorded onto the CAF 
system--
    (i) Specific tax period. Only documents which concern a matter(s) 
relating to a specific tax period will be recorded onto the CAF system. 
A power of attorney or tax information authorization filed in a matter 
unrelated to a specific period (e.g., the 100% penalty for failure to 
pay over withholding taxes imposed by section 6672 of the Internal 
Revenue Code, applications for an employer identification number, and 
requests for a private letter ruling request pertaining to a proposed 
transaction) cannot be recorded onto the CAF system.
    (ii) Future three-year limitation. Only documents which concern a 
tax period that ends no later than three years after the date on a power 
of attorney is received by the Internal Revenue Service will be recorded 
onto the CAF system. For example, a power of attorney received by the 
Internal Revenue Service on August 1, 1990, which indicates that the 
authorization applies to form 941 for the quarters ended December 31, 
1990 through December 31, 2000, will be recorded onto the CAF system for 
the applicable tax periods which end no later than July 31, 1993 (i.e., 
three years after the date of receipt by the Internal Revenue Service).
    (iii) Documents for prior tax periods. Documents which concern any 
tax period which has ended prior to the date on which a power of 
attorney is received by the Internal Revenue Service will be recorded 
onto the CAF system provided that matters concerning such years are 
under consideration by the Internal Revenue Service.
    (iv) Limitation on representatives recorded onto the CAF system. No 
more than three representatives appointed under a power of attorney or 
three persons designated under a tax information authorization will be 
recorded onto the CAF system. If more than three representatives are 
appointed under a power of attorney or more than three persons 
designated under a tax information authorization, only the first three 
names will be recorded onto the CAF system.

The fact that a power of attorney or tax information authorization 
cannot be recorded onto the CAF system is not determinative of the 
(current or future) validity of such document. (For example, documents 
which concern tax periods that end more than three years from the date 
of receipt by the IRS are not invalid for the period(s) not recorded 
onto the CAF system, but can be resubmitted at a later date.)
