  Subpart B_Federal Insurance Contributions Act (Chapter 21, Internal 
                          Revenue Code of 1954)
 
Sec.  31.3121(a)(1)-1  Annual wage limitation.

    (a) In general. (1) The term ``wages'' does not include that part of 
the remuneration paid by an employer to an employee within any calendar 
year--
    (i) After 1954 and before 1959 which exceeds the first $4,200 of 
remuneration,
    (ii) After 1958 and before 1966 which exceeds the first $4,800 of 
remuneration,
    (iii) After 1965 and before 1968 which exceeds the first $6,600 of 
remuneration,
    (iv) After 1967 and before 1972 which exceeds the first $7,800 of 
remuneration,
    (v) After 1971 and before 1973 which exceeds the first $9,000 of 
remuneration,
    (vi) After 1972 and before 1974 which exceeds the first $10,800 of 
remuneration,
    (vii) After 1973 and before 1975 which exceeds the first $13,200 of 
remuneration, or
    (viii) After 1974 which exceeds the amount equal to the contribution 
and benefit base (as determined under section 230 of the Social Security 
Act) which is effective for such calendar year

(exclusive of remuneration excepted from wages in accordance with 
paragraph (j) of Sec.  31.3121(a)-1 or Sec. Sec.  31.3121(a)(2)-1 to 
31.3121(a)(15)-1, inclusive) paid within the calendar year by an 
employer to the employee for employment performed for him at any time 
after 1936. For provisions relating to the treatment of tips for 
purposes of the annual wage limitation see Sec.  31.3121(q)-1.
    (2) The annual wage limitation applies only if the remuneration 
received during any 1 calendar year by an employee from the same 
employer for employment performed after 1936 exceeds the amount of such 
limitation. The limitation in such case relates to the amount of 
remuneration received during any 1 calendar year for employment after 
1936 and not to the amount of remuneration for employment performed in 
any 1 calendar year.

    Example. Employee A, in 1967 receives $7,000 from employer B in part 
payment of $8,000 due him from employment performed in 1967. In 1968 A 
receives from employer B the balance of $1,000 due him for employment 
performed in 1967, and thereafter in 1968 also receives $7,000 for 
employment performed in 1968 for employer B. The first $6,600 of the 
$7,000 received during 1967 is subject to the taxes in 1967. The 
remaining $400 received in 1967 is not included as wages and is not 
subject to the taxes. The balance of $1,000 received in 1968 for 
employment during 1967 is subject to the taxes during 1968 as is also 
the first $6,800 of the $7,000 thereafter received in 1968 ($1,000 plus 
$6,800 totaling $7,800, which is the annual wage limitation applicable 
to remuneration received in 1968 by an employee from any one employer). 
The remaining $200 received in 1968 is not included as wages and is not 
subject to the taxes.

    (3) If during a calendar year the employee receives remuneration 
from more than one employer, the annual wage limitation does not apply 
to the aggregate remuneration received from all of such employers, but 
instead applies to the remuneration received during such calendar year 
from each employer with respect to employment after 1936. In such case 
the first remuneration received in any calendar year after 1974 up to 
the amount equal to the contribution and benefit base (as determined 
under section 230 of the Social Security Act) (the first $13,200 
received in 1974, the first $10,800 received in 1973, the first $9,000 
received in 1972, the first $7,800 received in any calendar year after 
1967 and before 1972, the first $6,600 received in any calendar year 
after 1965 and before 1968, the first $4,800 received in any calendar 
year after 1958 and before 1966, or the first $4,200 received in any 
calendar year after 1954 and before 1959) from each

employer constitutes wages and is subject to the taxes, even though, 
under section 6413(c), the employee may be entitled to a special credit 
or refund of a portion of the employee tax deducted from his wages 
received during the calendar year. In this connection and in connection 
with the two examples immediately following, see Sec.  31.6413(c)-1, 
relating to special credits or refunds of employee tax. In connection 
with the annual wage limitation in the case of remuneration paid for 
services performed in the employ of the United States or a wholly owned 
instrumentality thereof, see Sec.  31.3122. In connection with the 
annual wage limitation in the case of remuneration paid for services 
performed in the employ of the Government of Guam, the Government of 
American Samoa, the District of Columbia, a political subdivision of the 
Government of Guam, or the Government of American Samoa, or any 
instrumentality of any of the foregoing which is wholly owned thereby, 
see Sec.  31.3125. In connection with the application of the annual wage 
limitation, see also paragraph (b) of this section, relating to the 
circumstances under which wages paid by a predecessor employer are 
deemed to be paid by his successor. In connection with the annual wage 
limitation in the case of remuneration paid after December 31, 1978, 
from two or more related corporations that compensate an employee 
through a common paymaster, see Sec.  31.3121(s)-1.

    Example 1. During 1968 employee C receives from employer D a salary 
of $1,300 a month for employment performed for D during the first 7 
months of 1968, or total remuneration of $9,100. At the end of the 6th 
month C has received $7,800 from employer D, and only that part of his 
total remuneration from D constitutes wages subject to the taxes. The 
$1,300 received by employee C from employer D in the 7th month is not 
included as wages and is not subject to the taxes. At the end of the 7th 
month C leaves the employ of D and enters the employ of E. C receives 
remuneration of $1,560 a month from employer E in each of the remaining 
5 months of 1968, or total remuneration of $7,800 from employer E. The 
entire $7,800 received by C from employer E constitutes wages and is 
subject to the taxes. Thus, the first $7,800 received from employer D 
and the entire $7,800 received from employer E constitute wages.
    Example 2. During the calendar year 1968 F is simultaneously an 
officer (an employee) of the X Corporation, the Y Corporation, and the Z 
Corporation and during such year receives a salary of $7,800 from each 
corporation. Each $7,800 received by F from each of the Corporations X, 
Y, and Z (whether or not such corporations are related) constitutes 
wages and is subject to the taxes.

    (b) Wages paid by predecessor attributed to successor. (1) If an 
employer (hereinafter referred to as a successor) during any calendar 
year acquires substantially all the property used in a trade or business 
of another employer (hereinafter referred to as a predecessor), or used 
in a separate unit of a trade or business of a predecessor, and if 
immediately after the acquisition the successor employs in his trade or 
business an individual who immediately prior to the acquisition was 
employed in the trade or business of such predecessor, then, for 
purposes of the application of the annual wage limitation set forth in 
paragraph (a) of this section, any remuneration (exclusive of 
remuneration excepted from wages in accordance with paragraph (j) of 
Sec.  31.3121(a)-1 or Sec. Sec.  31.3121(a)(2)-1 to 31.3121(a)(15)-1, 
inclusive) with respect to employment paid (or considered under this 
paragraph as having been paid) to such individual by the predecessor 
during such calendar year and prior to the acquisition shall be 
considered as having been paid by the successor.
    (2) The wages paid, or considered as having been paid, by a 
predecessor to an employee shall, for purposes of the annual wage 
limitation, be treated as having been paid to such employee by a 
successor if:
    (i) The successor during a calendar year acquired substantially all 
the property used in a trade or business, or used in a separate unit of 
a trade or business, of the predecessor;
    (ii) Such employee was employed in the trade or business of the 
predecessor immediately prior to the acquisition and is employed by the 
successor in his trade or business immediately after the acquisition; 
and
    (iii) Such wages were paid during the calendar year in which the 
acquisition occurred and prior to such acquisition.
    (3) The method of acquisition by an employer of the property of 
another

[[Page 26]]

employer is immaterial. The acquisition may occur as a consequence of 
the incorporation of a business by a sole proprietor or a partnership, 
the continuance without interruption of the business of a previously 
existing partnership by a new partnership or by a sole proprietor, or a 
purchase or any other transaction whereby substantially all the property 
used in a trade or business, or used in a separate unit of a trade or 
business, of one employer is acquired by another employer.
    (4) Substantially all the property used in a separate unit of a 
trade or business may consist of substantially all the property used in 
the performance of an essential operation of the trade or business, or 
it may consist of substantially all the property used in a relatively 
self-sustaining entity which forms a part of the trade or business.

    Example 1. The M Corporation which is engaged in the manufacture of 
automobiles, including the manufacture of automobile engines, 
discontinues the manufacture of the engines and transfers all the 
property used in such manufacturing operation to the N Company. The N 
Company is considered to have acquired a separate unit of the trade or 
business of the M Corporation, namely, its engine manufacturing unit.
    Example 2. The R Corporation which is engaged in the operation of a 
chain of grocery stores transfers one of such stores to the S Company. 
The S Company is considered to have acquired a separate unit of the 
trade or business of the R Corporation.

    (5) A successor may receive credit for wages paid to an employee by 
a predecessor only if immediately prior to the acquisition the employee 
was employed by the predecessor in his trade or business which was 
acquired by the successor and if immediately after the acquisition such 
employee is employed by the successor in his trade or business (whether 
or not in the same trade or business in which the acquired property is 
used). If the acquisition involves only a separate unit of a trade or 
business of the predecessor, the employee need not have been employed by 
the predecessor in that unit provided he was employed in the trade or 
business of which the acquired unit was a part.

    Example. The Y Corporation in 1968 acquires by purchase all the 
property of the X Company and immediately after the acquisition employs 
in its trade or business employee A, who, immediately prior to the 
acquisition, was employed by the X Company. The X Company has in 1968 
(the calendar year in which the acquisition occurs) and prior to the 
acquisition paid $5,000 of wages to A. The Y Corporation in 1968 pays to 
A remuneration of $5,000 with respect to employment. Only $2,800 of the 
remuneration paid by the Y Corporation is considered to be wages. For 
purposes of the $7,800 limitation, the Y Corporation is credited with 
the $5,000 paid to A by the X Company. If in the same calendar year, the 
Z Company acquires the property by purchase from the Y Corporation and A 
immediately after the acquistion is employed by the Z Company in its 
trade or business, no part of the remuneration paid to A by the Z 
Company in the year of the acquisition will be considered to be wages. 
The Z Company will be credited with the remuneration paid to A by the Y 
Corporation and also with the wages paid to A by the X Company 
(considered for purposes of the application of the $7,800 limitation as 
having also been paid by the Y Corporation).

    (6) Where a corporation described in section 501(c)(3) which is 
exempt from income tax under section 501(a) has in effect a certificate 
filed pursuant to section 3121(k), or pursuant to section 1426(1) of the 
Internal Revenue Code of 1939, waiving its exemption from the taxes 
imposed by the Act, the activity in which such corporation is engaged is 
considered to be its trade or business for the purpose of determining 
whether the transferred property was used in the trade or business of 
the predecessor and for the purpose of determining whether the 
employment by the predecessor and the successor of an individual whose 
services were retained by the successor constitute employment in a trade 
or business. Thus, if a charitable or religious organization, subject to 
the taxes by virtue of its certificate, acquires all the property of 
another such organization likewise subject to the taxes and retains the 
services of employees of the predecessor, wages paid to such employees 
by the predecessor in the year of the acquisition (and prior to such 
acquisition) will be attributed to the successor for purposes of the 
annual wage limitation.
