Editorial Note on Part 1
Editorial Note: IRS redesignated the following sections to appear below the undesignated center heading “Regulations Applicable to Certain Bonds Sold Prior to July 8, 1997” and preceding the undesignated center heading “Deductions for Personal Exemptions.” See 62 FR 25507 and 25513, May 9, 1997 for the specific sections involved in the redesignation.

§ 1.409A-6 Application of section 409A and effective dates. ( a ) *Statutory application and effective dates* — ( 1 ) *Application to amounts deferred* — ( i ) *In general.* Except as otherwise provided in this section, section 409A applies with respect to amounts deferred in taxable years beginning after December 31, 2004, and with respect to amounts deferred in taxable years beginning before January 1, 2005, if the plan under which the deferral is made is materially modified after October 3, 2004. For amounts deferred in taxable years beginning before January 1, 2005, under a plan that is materially modified after October 3, 2004, whether the plan complies with the requirements of section 409A and these regulations is determined by reference to the terms of the plan in effect as of, and any actions taken under the plan on or after, the date of the material modification. Section 409A is applicable with respect to earnings on amounts deferred only to the extent that section 409A is applicable with respect to the amounts deferred. Accordingly, section 409A does not apply with respect to earnings on amounts deferred before January 1, 2005, unless section 409A applies with respect to the amounts deferred. For this purpose, a right to earnings that is subject to a substantial risk of forfeiture (as defined in § 1.83-3(c)) or a requirement to perform further services, on an amount deferred that is not subject to a substantial risk of forfeiture (as defined in § 1.83-3(c)) or a requirement to perform further services, is not treated as earnings on the amount deferred, but a separate right to compensation. Except as otherwise provided in applicable guidance (see § 601.601(d)(2) of this chapter), the provisions of §§ 1.409A-1 through 1.409A-5 and this section provide the exclusive means of identifying agreements, methods, programs, or other arrangements subject to section 409A, and the exclusive means of satisfying the requirements of section 409A with respect to such agreements, methods, programs, or other arrangements.
( ii ) *Collectively bargained plans.* Section 409A does not apply with respect to amounts deferred under a plan maintained pursuant to one or more bona fide collective bargaining agreements in effect on October 3, 2004, for the period ending on the earlier of the date on which the last of such collective bargaining agreements terminates (determined without regard to any extension thereof after October 3, 2004) or December 31, 2009.
( 2 ) *Identification of date of deferral for statutory effective date purposes.* For purposes of determining whether section 409A is applicable with respect to an amount, the amount is considered deferred before January 1, 2005, if before January 1, 2005, the service provider had a legally binding right to be paid the amount, and the right to the amount was earned and vested. For purposes of this paragraph (a)(2), a right to an amount was earned and vested only if the amount was not subject to a substantial risk of forfeiture (as defined in § 1.83-3(c)) or a requirement to perform further services. Amounts to which the service provider did not have a legally binding right before January 1, 2005 (for example, because the service recipient retained discretion to reduce the amount), will not be considered deferred before January 1, 2005. In addition, amounts to which the service provider had a legally binding right before January 1, 2005, but the right to which was subject to a substantial risk of forfeiture or a requirement to perform further services after December 31, 2004, are not considered deferred before January 1, 2005, for purposes of the effective date. Notwithstanding the foregoing, an amount to which the service provider had a legally binding right before January 1, 2005, but for which the service provider was required to continue performing services to retain the right only through the completion of the payroll period (as defined in § 1.409A-1(b)(3)) that includes December 31, 2004, is not treated as subject to a requirement to perform further services (or a substantial risk of forfeiture) for purposes of the effective date. For purposes of this paragraph (a)(2), a stock option, stock appreciation right, or similar compensation that on or before December 31, 2004, was immediately exercisable for cash or substantially vested property (as defined in § 1.83-3(b)) is treated as earned and vested, regardless of whether the right would terminate if the service provider ceased providing services for the service recipient.
( 3 ) *Calculation of amount of compensation deferred for statutory effective date purposes* — ( i ) *Nonaccount balance plans.* The amount of compensation deferred before January 1, 2005, under a nonqualified deferred compensation plan that is a nonaccount balance plan (as defined in § 1.409A-1(c)(2)(i)(C)), equals the present value of the amount to which the service provider would have been entitled under the plan if the service provider voluntarily terminated services without cause on December 31, 2004, and received a payment of the benefits available from the plan on the earliest possible date allowed under the plan to receive a payment of benefits following the termination of services, and received the benefits in the form with the maximum value. Notwithstanding the foregoing, for any subsequent taxable year of the service provider, the grandfathered amount may increase to equal the present value of the benefit the service provider actually becomes entitled to, in the form and at the time actually paid, determined under the terms of the plan (including applicable limits under the Internal Revenue Code), as in effect on October 3, 2004, without regard to any further services rendered by the service provider after December 31, 2004, or any other events affecting the amount of or the entitlement to benefits (other than a participant election with respect to the time or form of an available benefit). For purposes of calculating the present value of a benefit under this paragraph (a)(3)(i), reasonable actuarial assumptions and methods must be used. Whether assumptions and methods are reasonable for this purpose is determined as of each date the benefit is valued for purposes of determining the grandfathered benefit, provided that any reasonable actuarial assumptions and methods that were used by the service recipient with respect to such benefit as of December 31, 2004, will continue to be treated as reasonable assumptions and methods for purposes of calculating the grandfathered benefit. Actuarial assumptions and methods will be presumed reasonable if they are the same as those used to value benefits under a qualified plan sponsored by the service recipient the benefits under which are part of the benefit formula under, or otherwise impact the amount of benefits under, the nonaccount balance nonqualified deferred compensation plan.
( ii ) *Account balance plans.* The amount of compensation deferred before January 1, 2005, under a nonqualified deferred compensation plan that is an account balance plan (as defined in § 1.409A-1(c)(2)(i)(A)), equals the portion of the service provider's account balance as of December 31, 2004, the right to which was earned and vested (as defined in paragraph (a)(2) of this section) as of December 31, 2004, plus any future contributions to the account, the right to which was earned and vested (as defined in paragraph (a)(2) of this section) as of December 31, 2004, to the extent such contributions are actually made.
( iii ) *Equity-based compensation plans.* For purposes of determining the amounts deferred before January 1, 2005, under an equity-based compensation plan, the rules of paragraph (a)(3)(ii) of this section governing account balance plans are applied except that the account balance is deemed to be the amount of the payment available to the service provider on December 31, 2004 (or that would be available to the service provider if the right were immediately exercisable) the right to which is earned and vested (as defined in paragraph (a)(2) of this section) as of December 31, 2004. For this purpose, the payment available to the service provider excludes any exercise price or other amount that must be paid by the service provider.
( iv ) *Earnings.* Earnings on amounts deferred under a plan before January 1, 2005, include only income (whether actual or notional) attributable to the amounts deferred under a plan as of December 31, 2004, or to such income. For example, notional interest earned under the plan on amounts deferred in an account balance plan as of December 31, 2004, generally will be treated as earnings on amounts deferred under the plan before January 1, 2005. Similarly, an increase in the amount of payment available pursuant to a stock option, stock appreciation right, or other equity-based compensation above the amount of payment available as of December 31, 2004, due to appreciation in the underlying stock after December 31, 2004, or accrual of other earnings such as dividends, is treated as earnings on the amount deferred. In the case of a nonaccount balance plan, earnings include the increase, due solely to the passage of time, in the present value of the future payments to which the service provider has obtained a legally binding right, the present value of which constituted the amounts deferred under the plan before January 1, 2005. Thus, for each year, there will be an increase (determined using the same interest rate used to determine the amounts deferred under the plan before January 1, 2005) resulting from the shortening of the discount period before the future payments are made, plus, if applicable, an increase in the present value resulting from the service provider's survivorship during the year. However, an increase in the potential benefits under a nonaccount balance plan due to, for example, an application of an increase in compensation after December 31, 2004, to a final average pay plan or subsequent eligibility for an early retirement subsidy, does not constitute earnings on the amounts deferred under the plan before January 1, 2005.
( v ) *Definition of plan.* For purposes of paragraphs (a)(1), (2), and (3) of this section, the term “plan” has the meaning provided in § 1.409A-1(c), except that the plan aggregation rules do not apply for purposes of the actuarial assumptions and methods used in paragraph (a)(3)(i) of this section. Accordingly, different reasonable actuarial assumptions and methods may be used to calculate the amounts deferred by a service provider in two different agreements, methods, programs, or other arrangements each of which constitutes a nonaccount balance plan.
( 4 ) *Material modifications* — ( i ) *In general.* Except as otherwise provided, a modification of a plan is a material modification if a benefit or right existing as of October 3, 2004, is materially enhanced or a new material benefit or right is added, and such material enhancement or addition affects amounts earned and vested before January 1, 2005. Such material benefit enhancement or addition is a material modification whether it occurs pursuant to an amendment or to the service recipient's exercise of discretion under the terms of the plan. For example, an amendment to a plan to add a provision that payments of deferred amounts earned and vested before January 1, 2005, may be allowed upon request if service providers are required to forfeit 20 percent of the amount of the payment (a haircut) would be a material modification to the plan. Similarly, a material modification would occur if a service recipient exercised discretion to accelerate vesting of a benefit under the plan to a date on or before December 31, 2004. However, it is not a material modification for a service recipient to exercise discretion over the time and manner of payment of a benefit to the extent such discretion is provided under the terms of the plan as of October 3, 2004. It is not a material modification for a service provider to exercise a right permitted under the plan as in effect on October 3, 2004. The amendment of a plan to bring the plan into compliance with the provisions of section 409A will not be treated as a material modification. However, a plan amendment or the exercise of discretion under the terms of the plan that materially enhances an existing benefit or right or adds a new material benefit or right will be considered a material modification even if the enhanced or added benefit would be permitted under section 409A. For example, the addition of a right to a payment upon an unforeseeable emergency of an amount earned and vested before January 1, 2005, would be considered a material modification. The reduction of an existing benefit is not a material modification. For example, the removal of a haircut provision generally would not constitute a material modification. The following modifications also are not material modifications for purposes of this paragraph (a)(4)(i): ( A ) The establishment of or contributions to a trust or other arrangement from which benefits under the plan are to be paid is not a material modification of the plan, provided that the contribution to the trust or other arrangement would not otherwise cause an amount to be includible in the service provider's gross income.
( B ) The modification of a provision requiring the immediate cancellation of a current deferral election, to require the cancellation of deferrals for the same length of time beginning with the first date at which the application of such cancellation would not violate section 409A (for example, the first date of the service provider's first taxable year following the cancellation).
( C ) Compliance with a domestic relations order (as defined in § 1.409A-3(j)(4)(ii)) with respect to payments to an individual other than the service provider, or an amendment to a plan to require compliance with a domestic relations order with respect to payments to an individual other than the service provider.
( D ) The modification of a plan providing a life annuity form of payment to permit an election between the existing life annuity form of payment and other forms of annuity payments that would be treated as a single form of payment with the existing life annuity form of payment under § 1.409A-2(b)(2)(ii).
( E ) The modification of a grandfathered plan to add a limited cashout feature consistent with § 1.409A-3(j)(4)(v) (exception to prohibition on accelerated payments).
( ii ) *Adoptions of new plans.* It is presumed that the adoption of a new plan or the grant of an additional benefit under an existing plan after October 3, 2004, and before January 1, 2005, constitutes a material modification of a plan. However, the presumption may be rebutted by demonstrating that the adoption of the plan or grant of the additional benefit was consistent with the service recipient's historical compensation practices. For example, the presumption that the grant of a discounted stock option on November 1, 2004, is a material modification of a plan may be rebutted by demonstrating that the grant was consistent with the historic practice of granting substantially similar discounted stock options (both as to terms and amounts) each November for a significant number of years. Notwithstanding paragraph (a)(4)(i) of this section and this paragraph (a)(4)(ii), the grant of an additional benefit under an existing plan that consists of a deferral of additional compensation not otherwise provided under the plan as of October 3, 2004, will be treated as a material modification of the plan only as to the additional deferral of compensation, if the plan explicitly identifies the additional deferral of compensation and provides that the additional deferral of compensation is subject to section 409A. Accordingly, amendments to conform a plan to the requirements of section 409A with respect to deferrals under a plan occurring after December 31, 2004, will not constitute a material modification of the plan with respect to amounts deferred that are earned and vested on or before December 31, 2004, provided that there is no concurrent material modification with respect to the amount of, or rights to, amounts deferred that were earned and vested on or before December 31, 2004. Similarly, a grant of an additional benefit under a new plan adopted after October 3, 2004, and before January 1, 2005, will not be treated as a material modification of an existing plan to the extent that the new plan explicitly identifies additional deferrals of compensation and provides that the additional deferrals of compensation are subject to section 409A.
( iii ) *Suspension or termination of a plan.* A cessation of deferrals under, or termination of, a plan, pursuant to the provisions of such plan, is not a material modification. Amending a plan to provide participants an election whether to terminate participation in a plan generally constitutes a material modification of the plan.
( iv ) *Changes to investment measures—account balance plans.* With respect to an account balance plan (as defined in § 1.409A-1(c)(2)(i)(A)), it is not a material modification to change a notional investment measure to, or to add to an existing investment measure, an investment measure that qualifies as a predetermined actual investment within the meaning of § 31.3121(v)(2)-1(d)(2) of this chapter or, for any given taxable year, reflects a reasonable rate of interest (determined in accordance with § 31.3121(v)(2)-1(d)(2)(i)(C) of this chapter).
( v ) *Stock rights.* The modification, extension, or renewal of a stock right will not constitute a material modification of the stock right, if the modification, extension, or renewal would not be treated as the grant of a new stock right under § 1.409A-1(b)(5)(v)(A), and would not result in the stock right being treated as having had a deferral feature from the date of grant pursuant to § 1.409A-1(b)(5)(v)(C).
( vi ) *Rescission of modifications.* Any modification to the terms of a plan that would inadvertently result in treatment as a material modification under this section is not considered a material modification of the plan to the extent the modification in the terms of the plan is rescinded by the earlier of a date before the right is exercised (if the change grants a discretionary right) or the last day of the taxable year of the service provider during which such change occurred. Thus, for example, if a service recipient modifies the terms of a plan on March 1 to allow an individual employee to elect a new change in the time or form of payment without realizing that such a change constituted a material modification that would subject the plan to the requirements of section 409A, and the modification is rescinded on November 1, then if no change in the time or form of payment has been made pursuant to the modification before November 1, the plan is not considered materially modified under this section.
( vii ) *Definition of plan.* For purposes of this paragraph (a)(4), the term “plan” has the same meaning provided in § 1.409A-1(c), except that the plan aggregation rules of § 1.409A-1(c)(2) do not apply.
( b ) *Regulatory applicability date.* § 1.409A-1, § 1.409A-2, § 1.409A-3 and this section are applicable for taxable years beginning on or after January 1, 2008.
