401(K) PLAN

Plain English Explanation and Comment

A 401(k) plan is a special kind of defined contribution plan which allows for so-called "elective contributions." These are employee contributions which are made on a pre-tax basis to the plan. A 401(k) plan is a defined contribution plan (or "individual account plan").  It is almost always a part of a Profit Sharing Plan, although the plan of which it is a part might not provide for any employer contributions.  A 401(k) plan is sometimes described as a "CODA."

An employer may establish a defined contribution plan that is a "cash or deferred arrangement", usually called a 401(k) plan. Under such a plan, a participant can elect to defer receiving a portion of their salary which is instead contributed on their behalf, before taxes, to the 401(k) plan. Sometimes the employer may match their contributions. There are special rules governing the operation of a 401(k) plan. For example, there is a dollar limit on the amount a participant may elect to defer each year. The dollar limit in $15,500 in 2008. A "catch-up" extra limit of $5,000 is also available for individuals who are or will turn 50 years of age during the calendar year The amount is adjusted annually by the Treasury Department to reflect changes in the cost of living. Other limits may apply to the amount that may be contributed on a participant's behalf. For example, if the participant is highly compensated, they may be limited depending on the extent to which rank and file employees participate in the plan. An employer must advise participant's of any limits that may apply to them.

Although a 401(k) plan is a retirement plan, participants may be permitted access to funds in the plan before retirement. For example, if a participant is an active employee, the plan may allow them to borrow from the plan. Also, the plan may permit a withdrawal on account of hardship, generally from the funds the participant contributed. The sponsor may want to encourage participation in the plan, but it cannot make participants' elective deferrals a condition for the receipt of other benefits, except for matching contributions.

Internal Revenue Code

401 (k) Cash or deferred arrangements

                          (1) General rule

        A profit-sharing or stock bonus plan, a pre-ERISA money purchase
    plan, or a rural cooperative plan shall not be considered as not
    satisfying the requirements of subsection (a) merely because the
    plan includes a qualified cash or deferred arrangement.

             (2) Qualified cash or deferred arrangement

        A qualified cash or deferred arrangement is any arrangement
    which is part of a profit-sharing or stock bonus plan, a pre-ERISA
    money purchase plan, or a rural cooperative plan which meets the
    requirements of subsection (a)--
            (A) under which a covered employee may elect to have the
        employer make payments as contributions to a trust under the
        plan on behalf of the employee, or to the employee directly in
        cash;
            (B) under which amounts held by the trust which are
        attributable to employer contributions made pursuant to the
        employee's election--
                (i) may not be distributable to participants or other
            beneficiaries earlier than--
                    (I) severance from employment, death, or disability,
                    (II) an event described in paragraph (10),
                    (III) in the case of a profit-sharing or stock bonus
                plan, the attainment of age 59\1/2\, or
                    (IV) in the case of contributions to a profit-
                sharing or stock bonus plan to which section 402(e)(3)
                applies, upon hardship of the employee, and

                (ii) will not be distributable merely by reason of the
            completion of a stated period of participation or the lapse
            of a fixed number of years;

            (C) which provides that an employee's right to his accrued
        benefit derived from employer contributions made to the trust
        pursuant to his election is nonforfeitable, and
            (D) which does not require, as a condition of participation
        in the arrangement, that an employee complete a period of
        service with the employer (or employers) maintaining the plan
        extending beyond the period permitted under section 410(a)(1)
        (determined without regard to subparagraph (B)(i) thereof).

        (3) Application of participation and discrimination
                                  standards

            (A) A cash or deferred arrangement shall not be treated as a
        qualified cash or deferred arrangement unless--
                (i) those employees eligible to benefit under the
            arrangement satisfy the provisions of section 410(b)(1), and
                (ii) the actual deferral percentage for eligible highly
            compensated employees (as defined in paragraph (5)) for the
            plan year bears a relationship to the actual deferral
            percentage for all other eligible employees for the
            preceding plan year which meets either of the following
            tests:
                    (I) The actual deferral percentage for the group of
                eligible highly compensated employees is not more than
                the actual deferral percentage of all other eligible
                employees multiplied by 1.25.
                    (II) The excess of the actual deferral percentage
                for the group of eligible highly compensated employees
                over that of all other eligible employees is not more
                than 2 percentage points, and the actual deferral
                percentage for the group of eligible highly compensated
                employees is not more than the actual deferral
                percentage of all other eligible employees multiplied by
                2.

          If 2 or more plans which include cash or deferred arrangements
            are considered as 1 plan for purposes of section 401(a)(4)
            or 410(b), the cash or deferred arrangements included in
            such plans shall be treated as 1 arrangement for purposes of
            this subparagraph.

        If any highly compensated employee is a participant under 2 or
        more cash or deferred arrangements of the employer, for purposes
        of determining the deferral percentage with respect to such
        employee, all such cash or deferred arrangements shall be
        treated as 1 cash or deferred arrangement. An arrangement may
        apply clause (ii) by using the plan year rather than the
        preceding plan year if the employer so elects, except that if
        such an election is made, it may not be changed except as
        provided by the Secretary.
            (B) For purposes of subparagraph (A), the actual deferral
        percentage for a specified group of employees for a plan year
        shall be the average of the ratios (calculated separately for
        each employee in such group) of--
                (i) the amount of employer contributions actually paid
            over to the trust on behalf of each such employee for such
            plan year, to
                (ii) the employee's compensation for such plan year.

            (C) A cash or deferred arrangement shall be treated as
        meeting the requirements of subsection (a)(4) with respect to
        contributions if the requirements of subparagraph (A)(ii) are
        met.
            (D) For purposes of subparagraph (B), the employer
        contributions on behalf of any employee--
                (i) shall include any employer contributions made
            pursuant to the employee's election under paragraph (2), and
                (ii) under such rules as the Secretary may prescribe,
            may, at the election of the employer, include--
                    (I) matching contributions (as defined in
                401(m)(4)(A)) which meet the requirements of paragraph
                (2)(B) and (C), and
                    (II) qualified nonelective contributions (within the
                meaning of section 401(m)(4)(C)).

            (E) For purposes of this paragraph, in the case of the first
        plan year of any plan (other than a successor plan), the amount
        taken into account as the actual deferral percentage of
        nonhighly compensated employees for the preceding plan year
        shall be--
                (i) 3 percent, or
                (ii) if the employer makes an election under this
            subclause, the actual deferral percentage of nonhighly
            compensated employees determined for such first plan year.

            (F) Special rule for early participation.--If an employer
        elects to apply section 410(b)(4)(B) in determining whether a
        cash or deferred arrangement meets the requirements of
        subparagraph (A)(i), the employer may, in determining whether
        the arrangement meets the requirements of subparagraph (A)(ii),
        exclude from consideration all eligible employees (other than
        highly compensated employees) who have not met the minimum age
        and service requirements of section 410(a)(1)(A).
            (G) A governmental plan (within the meaning of section
        414(d)) maintained by a State or local government or political
        subdivision thereof (or agency or instrumentality thereof) shall
        be treated as meeting the requirements of this paragraph.

                       (4) Other requirements

        (A) Benefits (other than matching contributions) must not be
                contingent on election to defer

            A cash or deferred arrangement of any employer shall not be
        treated as a qualified cash or deferred arrangement if any other
        benefit is conditioned (directly or indirectly) on the employee
        electing to have the employer make or not make contributions
        under the arrangement in lieu of receiving cash. The preceding
        sentence shall not apply to any matching contribution (as
        defined in section 401(m)) made by reason of such an election.

        (B) Eligibility of State and local governments and tax-exempt
                organizations

            (i) Tax-exempts eligible

                Except as provided in clause (ii), any organization
            exempt from tax under this subtitle may include a qualified
            cash or deferred arrangement as part of a plan maintained by
            it.
            (ii) Governments ineligible

                A cash or deferred arrangement shall not be treated as a
            qualified cash or deferred arrangement if it is part of a
            plan maintained by a State or local government or political
            subdivision thereof, or any agency or instrumentality
            thereof. This clause shall not apply to a rural cooperative
            plan or to a plan of an employer described in clause (iii).
            (iii) Treatment of Indian tribal governments

                An employer which is an Indian tribal government (as
            defined in section 7701(a)(40)), a subdivision of an Indian
            tribal government (determined in accordance with section
            7871(d)), an agency or instrumentality of an Indian tribal
            government or subdivision thereof, or a corporation
            chartered under Federal, State, or tribal law which is owned
            in whole or in part by any of the foregoing may include a
            qualified cash or deferred arrangement as part of a plan
            maintained by the employer.

        (C) Coordination with other plans

            Except as provided in section 401(m), any employer
        contribution made pursuant to an employee's election under a
        qualified cash or deferred arrangement shall not be taken into
        account for purposes of determining whether any other plan meets
        the requirements of section 401(a) or 410(b). This subparagraph
        shall not apply for purposes of determining whether a plan meets
        the average benefit requirement of section 410(b)(2)(A)(ii).

                   (5) Highly compensated employee

        For purposes of this subsection, the term ``highly compensated
    employee'' has the meaning given such term by section 414(q).

            (B) which was in existence on June 27, 1974, and which, on
        such date, included a salary reduction arrangement, and

        (C) Special rule for certain distributions

            A rural cooperative plan which includes a qualified cash or
        deferred arrangement shall not be treated as violating the
        requirements of section 401(a) or of paragraph (2) merely by
        reason of a hardship distribution or a distribution to a
        participant after attainment of age 59\1/2\. For purposes of
        this section, the term ``hardship distribution'' means a
        distribution described in paragraph (2)(B)(i)(IV) (without
        regard to the limitation of its application to profit-sharing or
        stock bonus plans).

      (8) Arrangement not disqualified if excess contributions
                                 distributed

        (A) In general

            A cash or deferred arrangement shall not be treated as
        failing to meet the requirements of clause (ii) of paragraph
        (3)(A) for any plan year if, before the close of the following
        plan year--
                (i) the amount of the excess contributions for such plan
            year (and any income allocable to such contributions) is
            distributed, or
                (ii) to the extent provided in regulations, the employee
            elects to treat the amount of the excess contributions as an
            amount distributed to the employee and then contributed by
            the employee to the plan.

        Any distribution of excess contributions (and income) may be
        made without regard to any other provision of law.

        (B) Excess contributions

            For purposes of subparagraph (A), the term ``excess
        contributions'' means, with respect to any plan year, the excess
        of--
                (i) the aggregate amount of employer contributions
            actually paid over to the trust on behalf of highly
            compensated employees for such plan year, over
                (ii) the maximum amount of such contributions permitted
            under the limitations of clause (ii) of paragraph (3)(A)
            (determined by reducing contributions made on behalf of
            highly compensated employees in order of the actual deferral
            percentages beginning with the highest of such percentages).

        (C) Method of distributing excess contributions

            Any distribution of the excess contributions for any plan
        year shall be made to highly compensated employees on the basis
        of the amount of contributions by, or on behalf of, each of such
        employees.

        (D) Additional tax under section 72(t) not to apply

            No tax shall be imposed under section 72(t) on any amount
        required to be distributed under this paragraph.

                excess deferral or contribution

            For purposes of paragraph (2)(C), a matching contribution
        (within the meaning of subsection (m)) shall not be treated as
        forfeitable merely because such contribution is forfeitable if
        the contribution to which the matching contribution relates is
        treated as an excess contribution under subparagraph (B), an
        excess deferral under section 402(g)(2)(A), or an excess
        aggregate contribution under section 401(m)(6)(B).

        (F) Cross reference

            For excise tax on certain excess contributions, see section
        4979.

                          (9) Compensation

        For purposes of this subsection, the term ``compensation'' has
    the meaning given such term by section 414(s).

             (10) Distributions upon termination of plan

        (A) In general

            An event described in this subparagraph is the termination
        of the plan without establishment or maintenance of another
        defined contribution plan (other than an employee stock
        ownership plan as defined in section 4975(e)(7)).

        (B) Distributions must be lump sum distributions

            (i) In general

                A termination shall not be treated as described in
            subparagraph (A) with respect to any employee unless the
            employee receives a lump sum distribution by reason of the
            termination.
            (ii) Lump-sum distribution

                For purposes of this subparagraph, the term ``lump-sum
            distribution'' has the meaning given such term by section
            402(e)(4)(D) (without regard to subclauses (I), (II), (III),
            and (IV) of clause (i) thereof). Such term includes a
            distribution of an annuity contract from--
                    (I) a trust which forms a part of a plan described
                in section 401(a) and which is exempt from tax under

    (11) Adoption of simple plan to meet nondiscrimination tests

        (A) In general

            A cash or deferred arrangement maintained by an eligible
        employer shall be treated as meeting the requirements of
        paragraph (3)(A)(ii) if such arrangement meets--
                (i) the contribution requirements of subparagraph (B),
                (ii) the exclusive plan requirements of subparagraph
            (C), and
                (iii) the vesting requirements of section 408(p)(3).

        (B) Contribution requirements

            (i) In general

                The requirements of this subparagraph are met if, under
            the arrangement--
                    (I) an employee may elect to have the employer make
                elective contributions for the year on behalf of the
                employee to a trust under the plan in an amount which is
                expressed as a percentage of compensation of the
                employee but which in no event exceeds the amount in
                effect under section 408(p)(2)(A)(ii),
                    (II) the employer is required to make a matching
                contribution to the trust for the year in an amount
                equal to so much of the amount the employee elects under
                subclause (I) as does not exceed 3 percent of
                compensation for the year, and
                    (III) no other contributions may be made other than
                contributions described in subclause (I) or (II).
            (ii) Employer may elect 2-percent nonelective
                    contribution

                An employer shall be treated as meeting the requirements
            of clause (i)(II) for any year if, in lieu of the
            contributions described in such clause, the employer elects
            (pursuant to the terms of the arrangement) to make
            nonelective contributions of 2 percent of compensation for
            each employee who is eligible to participate in the
            arrangement and who has at least $5,000 of compensation from
            the employer for the year. If an employer makes an election
            under this subparagraph for any year, the employer shall
            notify employees of such election within a reasonable period
            of time before the 60th day before the beginning of such
            year.
            (iii) Administrative requirements

                (I) In general

                    Rules similar to the rules of subparagraphs (B) and
                (C) of section 408(p)(5) shall apply for purposes of
                this subparagraph.
                (II) Notice of election period

                    The requirements of this subparagraph shall not be
                treated as met with respect to any year unless the
                employer notifies each employee eligible to participate,
                within a reasonable period of time before the 60th day
                before the beginning of such year (and, for the first
                year the employee is so eligible, the 60th day before
                the first day such employee is so eligible), of the
                rules similar to the rules of section 408(p)(5)(C) which
                apply by reason of subclause (I).

        (C) Exclusive plan requirement

            The requirements of this subparagraph are met for any year
        to which this paragraph applies if no contributions were made,
        or benefits were accrued, for services during such year under
        any qualified plan of the employer on behalf of any employee
        eligible to participate in the cash or deferred arrangement,
        other than contributions described in subparagraph (B).

        (D) Definitions and special rule

            (i) Definitions

                For purposes of this paragraph, any term used in this
            paragraph which is also used in section 408(p) shall have
            the meaning given such term by such section.
            (ii) Coordination with top-heavy rules

                A plan meeting the requirements of this paragraph for
            any year shall not be treated as a top-heavy plan under
            section 416 for such year if such plan allows only
            contributions required under this paragraph.

       (12) Alternative methods of meeting nondiscrimination
                                requirements

        (A) In general

            A cash or deferred arrangement shall be treated as meeting
        the requirements of paragraph (3)(A)(ii) if such arrangement--
                (i) meets the contribution requirements of subparagraph
            (B) or (C), and
                (ii) meets the notice requirements of subparagraph (D).

        (B) Matching contributions

            (i) In general

                The requirements of this subparagraph are met if, under
            the arrangement, the employer makes matching contributions
            on behalf of each employee who is not a highly compensated
            employee in an amount equal to--
                    (I) 100 percent of the elective contributions of the
                employee to the extent such elective contributions do
                not exceed 3 percent of the employee's compensation, and
                    (II) 50 percent of the elective contributions of the
                employee to the extent that such elective contributions
                exceed 3 percent but do not exceed 5 percent of the
                employee's compensation.
            (ii) Rate for highly compensated employees

                The requirements of this subparagraph are not met if,
            under the arrangement, the rate of matching contribution
            with respect to any elective contribution of a highly
            compensated employee at any rate of elective contribution is
            greater than that with respect to an employee who is not a
            highly compensated employee.
            (iii) Alternative plan designs

                If the rate of any matching contribution with respect to
            any rate of elective contribution is not equal to the
            percentage required under clause (i), an arrangement shall
            not be treated as failing to meet the requirements of clause
            (i) if--
                    (I) the rate of an employer's matching contribution
                does not increase as an employee's rate of elective
                contributions increase, and
                    (II) the aggregate amount of matching contributions
                at such rate of elective contribution is at least equal
                to the aggregate amount of matching contributions which
                would be made if matching contributions were made on the
                basis of the percentages described in clause (i).

        (C) Nonelective contributions

            The requirements of this subparagraph are met if, under the
        arrangement, the employer is required, without regard to whether
        the employee makes an elective contribution or employee
        contribution, to make a contribution to a defined contribution
        plan on behalf of each employee who is not a highly compensated
        employee and who is eligible to participate in the arrangement
        in an amount equal to at least 3 percent of the employee's
        compensation.

        (D) Notice requirement

            An arrangement meets the requirements of this paragraph if,
        under the arrangement, each employee eligible to participate is,
        within a reasonable period before any year, given written notice
        of the employee's rights and obligations under the arrangement
        which--
                (i) is sufficiently accurate and comprehensive to
            apprise the employee of such rights and obligations, and
                (ii) is written in a manner calculated to be understood
            by the average employee eligible to participate.

        (E) Other requirements

            (i) Withdrawal and vesting restrictions

                An arrangement shall not be treated as meeting the
            requirements of subparagraph (B) or (C) of this paragraph
            unless the requirements of subparagraphs (B) and (C) of
            paragraph (2) are met with respect to all employer
            contributions (including matching contributions) taken into
            account in determining whether the requirements of
            subparagraphs (B) and (C) of this paragraph are met.
            (ii) Social security and similar contributions not
                    taken into account

                An arrangement shall not be treated as meeting the
            requirements of subparagraph (B) or (C) unless such
