  Subpart B_Federal Insurance Contributions Act (Chapter 21, Internal 
                          Revenue Code of 1954)
 
Sec. 31.3121(k)-1  Waiver of exemption from taxes.

    (a) Who may file a waiver certificate--(1) In general. If services 
performed in the employ of an organization are excepted from employment 
under section 3121(b)(8)(B), the organization may file a waiver 
certificate on Form SS-15, together with a list on Form SS-15a, 
certifying that it desires to have the Federal old-age, survivors, and 
disability insurance system established by title II of the Social 
Security Act extended to services performed by its employees. (For 
provisions relating to the exception under section 3121(b)(8)(B), see 
that section and Sec. 31.3121(b)(8)-2.) A certificate in effect under 
section 1426(1) of the Internal Revenue Code of 1939 on December 31, 
1954, remains in effect under, and is subject to the provisions of, 
section 3121(k). If the period covered by a certificate filed under 
section 3121(k), or under section 1426(l) of the Internal Revenue Code 
of 1939, is terminated by an organization, a certificate may not 
thereafter be filed by the organization under section 3121(k). For 
regulations relating to certificates filed under section 1426(l) of the 
Internal Revenue Code of 1939, see 26 CFR (1939) 408.216 (Regulations 
128).
    (2) Organizations having two separate groups of employees. If an 
organization is eligible to file a certificate under section 3121(k), 
and the organization employs both individuals who are in positions 
covered by a pension, annuity, retirement, or similar fund or system 
established by a State or by a political subdivision thereof and 
individuals who are not in such positions, the organization shall divide 
its employees into two separate groups for purposes of any certificate 
filed after August 28, 1958. One group shall consist of all employees 
who are in positions covered by such a fund or system and (i) are 
members of such fund or system, or (ii) are not members of such fund or 
system but are eligible to become members thereof. The other group shall 
consist of all remaining employees. An organization which has so divided 
its employees into two groups may file a certificate after August 28, 
1958, with respect to the employees in either group, or may file a 
separate certificate after such date with respect to employees in each 
group.
    (3) Certificates filed before September 14, 1960. A certificate 
filed before September 14, 1960, is void unless at least two-thirds of 
the employees, determined on the basis of the facts which existed as of 
the date the certificate was filed, concurred in the filing of the 
certificate, and the organization certified to such concurrence in the 
certificate. All individuals who were employees of the organization 
within the meaning of section 3121(d) (see Sec. 31.3121(d)-1) shall be 
included in determining whether two-thirds of the employees of the 
organization concurred in the filing of the certificate; except that 
there shall not be included (i) those employees who at the time of the 
filing of the certificate were performing for the organization services 
only of the character specified in paragraphs (8)(A), (10)(B), and (13) 
of section 3121(b) (see Sec. Sec. 31.3121(b)(8)-1, 31.3121(b)(10)-2, 
and 31.3121(b)(13)-1, respectively), (ii) those alien employees who at 
the time of the filing of the certificate were performing services for 
such organization under an arrangement which provided for the 
performance only of services outside the United States not on or in 
connection with an American vessel or American aircraft, and (iii) in 
connection with certificates filed after August 28, 1958, those 
employees who at the time of the filing of the certificate were in a 
group to which such certificate was not applicable because of the 
provisions of section 3121(k)(1)(E). (See paragraph (a)(2) of this 
section.) As used in this subparagraph, the term ``alien employee'' does 
not include an employee who was a citizen of the Commonwealth of Puerto 
Rico or a citizen of the Virgin Islands, and the term ``United States''

[[Page 78]]

includes Puerto Rico and the Virgin Islands.
    (b) Execution and amendment of certificate--(1) Use of prescribed 
forms. An organization filing a certificate pursuant to section 3121(k) 
shall use Form SS-15, in accordance with the regulations and 
instructions applicable thereto. The certificate may be filed only if it 
is accompanied by a list on Form SS-15a, containing the signature, 
address, and social security account number, if any, of each employee, 
if any, who concurs in the filing of the certificate. (For provisions 
relating to account numbers, see Sec. 31.6011(b)-2.) If no employee 
concurs in a certificate filed after September 13, 1960, that fact 
should be stated on the Form SS-15a. (For provisions relating to the 
concurrence of employees in certificates filed before September 14, 
1960, see paragraph (a)(3) of this section.)
    (2) Amendment of list on Form SS- 15a--(i) Certificate filed after 
August 28, 1958. The list on Form SS-15a accompanying a certificate 
filed after August 28, 1958, under section 3121(k), may be amended at 
any time before the expiration of the twenty-fourth month following the 
calendar quarter in which the certificate is filed, by filing a 
supplemental list or lists on Form SS-15a Supplement, containing the 
signature, address, and social security account number, if any, of each 
additional employee who concurs in the filing of the certificate.
    (ii) Certificate filed before August 29, 1958. The list on Form SS-
15a which accompanied a certificate filed before August 29, 1958, under 
section 3121(k) or under section 1426(l) of the Internal Revenue Code of 
1939, may be amended by filing a supplemental list or lists on Form SS-
15a Supplement at any time after August 31, 1954, and before the 
expiration of the twenty-fourth month following the first calendar 
quarter for which the certificate was in effect, or before January 1, 
1959, whichever is the later.
    (3) Where to file certificate or amendment. The certificate on Form 
SS-15 and accompanying list on Form SS-15a of an organization which is 
required to make a return on Form 941 pursuant to Sec. 31.6011(a)-1 or 
Sec. 31.6011(a)-4 shall be filed with the internal revenue officer 
designated in the instructions applicable to Form SS-15 and Form SS-15a. 
The Form SS-15 and Form SS-15a of any other organization shall be filed 
in accordance with the provisions of Sec. 31.6091-1 which are otherwise 
applicable to returns. Each Form SS-15a Supplement shall be filed with 
the internal revenue officer with whom the related Forms SS-15 and SS-
15a were filed.
    (c) Effect of waiver--(1) In general. The exception from employment 
under section 3121(b)(8)(B) does not apply to services with respect to 
which a certificate, filed pursuant to section 3121(k), or section 
1426(l) of the Internal Revenue Code of 1939, is in effect. (See 
Sec. Sec. 31.3121(b)(8) and 31.3121(b)(8)-2). If an organization has 
divided its employees into two groups, as set forth in paragraph (a)(2) 
of this section, a certificate filed with respect to either group shall 
have no effect with respect to services performed by an employee as a 
member of the other group; and the provisions of this subparagraph shall 
apply as if each group were separately employed by a different 
organization. A certificate is not terminated if the organization loses 
its exemption under section 501(a) as an organization of the character 
described in section 501(c)(3), but continues effective with respect to 
any subsequent periods during which the organization is so exempt. The 
certificate of an organization may be in effect without being applicable 
to services performed by every employee of the organization. 
Subparagraph (2) of this paragraph relates to the beginning of the 
period for which a certificate is in effect. Subparagraph (3) of this 
paragraph relates to the services with respect to which a certificate is 
in effect. Even though a certificate is in effect with respect to the 
services of an employee, such services may be excepted from employment 
under some provision of section 3121(b) other than paragraph (8)(B) 
thereof. For example, service performed in any calendar quarter in the 
employ of an organization described in section 501(c)(3) and exempt from 
income tax under section 501(a) is excepted from employment under 
section 3121(b)(10)(A) if the remuneration for such service is less than 
$50, regardless of whether the organization files a certificate.

[[Page 79]]

    (2) Beginning of effective period of waiver--(i) Certificate filed 
after July 30, 1965. A certificate filed after July 30, 1965, by an 
organization pursuant to section 3121(k) shall be in effect for the 
period beginning with one of the following dates, which shall be 
designated by the organization on the certificate:
    (a) The first day of the calendar quarter in which the certificate 
is filed,
    (b) The first day of the calendar quarter immediately following the 
quarter in which the certificate is filed, or
    (c) The first day of any calendar quarter preceding the calendar 
quarter in which the certificate is filed, except that such date may not 
be earlier than the first day of the 20th calendar quarter preceding the 
quarter in which such certificate is filed. Thus, a certificate filed in 
December 1965 may be made effective, pursuant to this paragraph 
(c)(2)(i)(c), for the period beginning with the first day of the 
calendar quarter beginning October 1, 1960, or the first day of any 
other calendar quarter beginning after October 1, 1960, and before 
October 1, 1965.
    (ii) Certificate filed after August 28, 1958, and before July 31, 
1965. A certificate filed after August 28, 1958, and before July 31, 
1965, by an organization pursuant to section 3121(k) shall be in effect 
for the period beginning with one of the following dates, which shall be 
designated by the organization on the certificate:
    (a) The first day of the calendar quarter in which the certificate 
is filed,
    (b) The first day of the calendar quarter immediately following the 
quarter in which the certificate is filed, or
    (c) The first day of any calendar quarter preceding the calendar 
quarter in which the certificate is filed, except that, in the case of a 
certificate filed before 1960, such date may not be earlier than January 
1, 1956, and in the case of a certificate filed after 1959 (but before 
July 31, 1965), such date may not be earlier than the first day of the 
fourth calendar quarter preceding the quarter in which the certificate 
is filed. Thus, a certificate filed in December 1959 may be made 
effective for the calendar quarter beginning January 1, 1956; but a 
certificate filed in January 1960 may not be made effective for a 
calendar quarter beginning before January 1, 1959.
    (iii) Certificate filed after 1956 and before August 29, 1958. A 
certificate filed by an organization after 1956 and before August 29, 
1958 pursuant to section 3121(k), became effective for the period 
beginning with one of the following dates, as designated by the 
organization on the certificate:
    (a) The first day of the calendar quarter in which the certificate 
was filed, or
    (b) The first day of the calendar quarter immediately following the 
quarter in which the certificate was filed.
    (iv) Certificate filed before 1957. A certificate filed before 1957 
pursuant to section 3121(k) became effective for the period beginning 
with the first day following the close of the calendar quarter in which 
the certificate was filed. In no case, however, shall a certificate 
filed under the provisions of section 3121(k) be in effect with respect 
to services performed before January 1, 1955. (For regulations relating 
to waiver certificates filed under section 1426(l) of the Internal 
Revenue Code of 1939, see 26 CFR (1939) 408.216 (Regulations 128).)
    (3) Services to which certificate applies--(i) In general. If an 
organization's certificate is in effect (see paragraph (c)(2) of this 
section), the certificate becomes effective with respect to services 
performed in its employ by each individual (a) who enters the employ of 
the organization after the calendar quarter in which the certificate is 
filed, as set forth in paragraph (c)(3)(ii) of this section, or (b) 
whose signature appears on the list on Form SS-15a, as set forth in 
paragraph (c)(3)(iii) of this section, or (c) whose signature appears on 
a Form SS-15a Supplement, as set forth in paragraph (c)(3)(iv) or (v) of 
this section. The first date on which such a certificate becomes 
effective with respect to an employee's services shall be the earliest 
date applicable under this subparagraph. An organization's certificate 
is not effective with respect to the services of an employee who is in 
its employ in the calendar quarter in which the certificate is filed and 
who does not sign Form SS-15a or Form SS-15a Supplement, so long as his 
employment relationship with the

[[Page 80]]

organization, at the close of the calendar quarter in which the 
certificate is filed and thereafter, continues without interruption.
    (ii) Employee hired after quarter in which certificate is filed. If 
an individual enters the employ of an organization on or after the first 
day following the close of the calendar quarter in which the 
organization files a certificate pursuant to section 3121(k), the 
certificate shall be in effect with respect to services performed by the 
individual in the employ of the organization on and after the day he 
enters the employ of the organization. A former employee of the 
organization who is rehired on or after the first day following the 
close of the calendar quarter in which such a certificate is filed shall 
be considered to have entered the employ of the organization after such 
calendar quarter, regardless of whether such individual concurred in the 
filing of the certificate.
    (iii) Employee who signs Form SS-15a. A certificate on Form SS-15 
filed by an organization pursuant to section 3121(k) shall be in effect 
with respect to services performed by an individual in the employ of the 
organization on and after the first day for which the certificate is in 
effect, if such individual's signature appears on the list on Form SS-
15a which accompanies such certificate.
    (iv) Employee who signs Form SS-15a Supplement to concur in 
certificate filed after August 28, 1958. If the list on Form SS-15a 
accompanying a certificate filed after August 28, 1958, by an 
organization pursuant to section 3121(k) is amended in accordance with 
paragraph (b)(2)(i) of this section by the filing of a supplemental list 
on Form SS-15a Supplement, the certificate shall be in effect with 
respect to the services of each individual whose signature appears on 
the supplemental list, performed in the employ of the organization--
    (a) On and after the first day for which the certificate is in 
effect, if the supplemental list is filed on or before the last day of 
the month following the calendar quarter in which the certificate is 
filed, or
    (b) On and after the first day of the calendar quarter in which the 
supplemental list is filed, if such list is filed after the close of the 
first month following the calendar quarter in which the certificate is 
filed.
    (v) Employee who signed Form SS-15a Supplement to concur in 
certificate filed before August 29, 1958. If the list on Form SS-15a 
which accompanied a certificate filed before August 29, 1958, by an 
organization pursuant to section 3121(k), or pursuant to section 1426(l) 
of the Internal Revenue Code of 1939, was amended in accordance with 
paragraph (b)(2)(ii) of this section by the filing of a supplemental 
list on Form SS-15a Supplement, the certificate shall be in effect with 
respect to the services of each individual whose signature appears on 
the supplemental list, performed in the employ of the organization--
    (a) On and after the first day for which the certificate is in 
effect, if the supplemental list was filed on or before the last day of 
the month following the first calendar quarter for which the certificate 
was in effect, or
    (b) On and after the first day following the close of the calendar 
quarter in which the supplemental list was filed, but not before January 
1, 1955, if such list was filed after the close of the first month 
following the first calendar quarter for which the certificate is in 
effect.
    (4) Administrative provisions applicable when certificate has 
retroactive effect. For purposes of computing interest and for purposes 
of section 6651 (relating to addition to tax for failure to file tax 
return), in any case in which a certificate filed pursuant to section 
3121(k)(1) is effective pursuant to section 3121(k)(1)(B)(iii) (as 
originally enacted and as amended by section 316(a) of the Social 
Security Amendments of 1965) for one or more calendar quarters prior to 
the quarter in which the certificate is filed, the due date for the 
return and payment of the tax for such prior calendar quarters resulting 
from the filing of such certificate shall be the last day of the 
calendar month following the calendar quarter in which the certificate 
is filed. The statutory period for the assessment of the tax for such 
prior calendar quarters shall not expire before the expiration of 3 
years from such

[[Page 81]]

due date. A waiver certificate (as described in section 3121(k)(1) and 
this section) furnished to the Internal Revenue Service after February 
12, 1976, shall not be considered filed with the Internal Revenue 
Service unless interest paid to the organization (or credited to its 
account) in connection with a claim for credit or refund of taxes, which 
claim was based upon the exemption from taxes the organization is 
waiving by such certificate, is repaid. The interest so paid must be 
repaid only to the extent such interest relates to any taxes for which 
the organization or its employees would be liable by reason of the 
waiver certificate. Furthermore, when a waiver certificate has been 
filed prior to the payment of a refund of taxes based upon the exemption 
from taxes the organization in waiving, no credit or refund in respect 
of the taxes for which the exemption has been waived shall be allowed. 
If repayment of the interest is made as required by this subparagraph, 
on or before the last day of the calendar month following the calendar 
quarter in which the certificate is furnished to the Internal Revenue 
Service, such certificate shall be considered to have been filed on the 
date it was originally furnished. If repayment occurs after that day, 
such certificate shall be considered to have been filed on the date of 
the repayment. References in this subparagraph to a waiver certificate 
refer also to any supplement to such a certificate.
    (d) Termination of waiver by organization. (1) The period for which 
a certificate filed pursuant to section 3121(k), or pursuant to section 
1426(l) of the Internal Revenue Code of 1939, is in effect may be 
terminated by the organization upon giving to the district director with 
whom the organization is filing returns 2 years' advance notice in 
writing of its desire to terminate the effect of the certificate at the 
end of a specified calendar quarter, but only if, at the time of the 
receipt of such notice by the district director, the certificate has 
been in effect for a period of not less than 8 years. The notice of 
termination shall be signed by the president or other principal officer 
of the organization. Such notice shall be dated and shall show (i) the 
title of the officer signing the notice, (ii) the name, address, and 
identification number of the organization, (iii) the district director 
with whom the certificate was filed, (iv) the date on which the 
certificate became effective, and (v) the date on which the certificate 
is to be terminated. No particular form is prescribed for the notice of 
termination.
    (2) In computing the effective period which must precede the date of 
receipt of the notice of termination, there shall be disregarded any 
period or periods as to which the organization was not exempt from 
income tax under section 501(a) as an organization of the character 
described in section 501(c)(3) or under section 101(6) of the Internal 
Revenue Code of 1939.
    (3) The notice of termination may be revoked by the organization by 
giving, prior to the close of the calendar quarter specified in the 
notice of termination, a written notice of such revocation. The notice 
of revocation shall be filed with the district director with whom the 
notice of termination was filed. The notice of revocation shall be 
signed by the president or other principal officer of the organization. 
Such notice shall be dated and shall show (i) the title of the officer 
signing the notice, (ii) the name, address, and identification number of 
the organization, and (iii) the date of the notice of termination to be 
revoked. No particular form is prescribed for the notice of revocation.
    (e) Termination of waiver by Commissioner. (1) The period for which 
a certificate filed pursuant to section 3121(k), or pursuant to section 
1426(l) of the Internal Revenue Code of 1939, is in effect may be 
terminated by the Commissioner, with the prior concurrence of the 
Secretary of Health, Education, and Welfare, upon a finding by the 
Commissioner that the organization has failed to comply substantially 
with the requirements applicable with respect to the taxes imposed by 
the act (or the corresponding provisions of prior law) or is no longer 
able to comply therewith. The Commissioner shall give the organization 
not less than 60 days' advance notice in writing that the period covered 
by the certificate will terminate at the end of the calendar quarter 
specified in the notice of termination.

[[Page 82]]

    (2) The notice of termination may be revoked by the Commissioner, 
with the prior concurrence of the Secretary of Health, Education, and 
Welfare, by giving written notice of revocation to the organization 
before the close of the calendar quarter specified in the notice of 
termination.
