Page 2                                                             For applications submitted to conform to the 2020 RA List

I. Nondiscriminatory Allocations
This part of the worksheet deals with the safe harbor requirements of section 1.401(a)(4)-2(b) of the Regulations. Satisfaction of the safe 
harbor requirements under section 1.401(a)(4)-2(b) does not mean that the plan complies with all of the requirements of IRC 401(a)(4). 

Line a. When an employer submits a determination letter application, the employer must indicate whether the plan is intended to satisfy 
one of the design-based safe harbors under the section 401(a)(4) regulations, and whether the employer elects to have the plan reviewed 
to determine if it so meets. A design-based safe harbor allows for a determination that the plan, by design, satisfies the nondiscrimination 
in amount requirement of 1.401(a)(4)-1(b)(2) but is not a determination whether the plan satisfies the requirements of 1.401(a)(4)-1(b)(3) 
and (4). 

II. Design-Based Safe Harbors
This part of the worksheet deals with the design-based safe harbors. A design-based safe harbor allows for a determination that the plan, 
by design, satisfies the nondiscrimination in amount requirement without the need to test the actual allocations or benefits under the plan. 
The employer is asked to specify the particular safe harbor that the plan is intended to satisfy. Those lines of the worksheet that do not 
pertain to the specified safe harbor should not be completed. The remaining part of the worksheet (Part III) should be completed only in the 
case of design-based safe harbor plans. 

Line a. The safe harbor for defined contribution plans with uniform allocation formulas is satisfied if the plan (including an ESOP) allocates 
contributions and forfeitures under a formula that allocates the same percentage of compensation, the same dollar amount, or the same 
amount per unit of service (not to exceed one week) to every participant under the plan. For this purpose, the contributions taken into 
account are all employer contributions other than elective and matching contributions that are subject to the actual deferral percentage 
(ADP) and actual contribution percentage (ACP) requirements of sections 401(k) and 401(m), respectively.
A plan will not fail to satisfy these requirements merely because:
1)  Allocations are limited in accordance with section 415 or section 409(n). 
2)  Allocations are limited to a maximum dollar amount or a maximum percentage of compensation, or the plan limits the compensation 
         taken into account, provided these limits apply either to all employees under the plan or only to some or all highly compensated 
         employees under the plan.
3)  Allocations  for  all  employees  are  conditioned  on  a  last  day  of  the  plan  year  or  minimum  hours  of  service  (not  over  1,000) 
         requirement. (An exception can be made for all employees who terminate or just for those who terminate because of retirement, 
         disability, death, or military service.)
4)  The plan provides for permitted disparity in a manner that satisfies section 401(l).
5)  The plan provides one or more entry dates during the plan year.
6)  One or more HCEs receive lower allocations than would otherwise be provided if the plan satisfied the safe harbor disregarding 
         this rule.
7)  The plan provides that an employee’s allocation is the greater of, or the sum of, two or more formulas each of which satisfies 
         the safe harbor. Formulas that are available solely to some or all nonhighly compensated employees (but not to any highly 
         compensated employees) fall within this exception, as do the following types of top-heavy formulas: formulas available solely 
         to all non-key employees on the same terms as other formulas; formulas conditioned on the plan being top-heavy and formulas 
         available only to all non-key employees who have not separated from service before the end of the plan year, provided the plan 
         would meet coverage when employees receiving a top-heavy minimum allocation only are not counted as benefiting.
A plan will not satisfy this safe harbor if it weights allocations on the basis of age or service.
1.401(a)(4)-2(b)(2) and (4)

Line b. A target benefit plan is a defined contribution money purchase pension plan under which contributions to an employee’s account 
are determined by reference to the amounts necessary to fund the employee’s stated benefit under the plan. The benefit formula under 
a target benefit plan is similar to that under a defined benefit plan. However, the actual benefit that the participant will receive will be the 
account balance which will vary from the stated benefit based on investment performance. Thus, the stated benefit is a “target benefit.”
An employer may not elect to have an individually designed plan reviewed to determine whether it meets the target benefit safe harbor. 
However, pre-approved specimen plans are so reviewed. A target benefit plan satisfies the target benefit plan safe harbor if it meets the 
following requirements:
1)  Each employee’s stated benefit is expressed as a straight life annuity under a formula that would satisfy the fractional rule unit 
         credit or flat benefit safe harbor and the defined benefit uniformity requirements if the plan were in fact a defined benefit plan (see 
         lines XI.a. through XI.a.(iii) of Worksheet 5A). Thus, for example, in order to satisfy the flat benefit safe harbor, a target benefit plan 
         with a flat benefit formula must provide that the maximum benefit under the plan is reduced pro rata for years of credited service 
         less than 25. Likewise, in order for the target benefit formula to satisfy one of the defined benefit design-based safe harbors, 
         the plan’s definition of compensation for purposes of the benefit formula must satisfy the compensation formula requirements 
         described in lines a. and b. of Part XI of Worksheet 5A.

2)  The stated benefit may not credit service for years before the employee first benefited under the plan nor service in years in which 
        the target benefit safe harbor was not satisfied. However, these rules generally do not apply to a plan that was adopted and in 
        effect on September 19, 1991, and that was qualified under prior law.
3)  Employer contributions are based on the employee’s stated benefit using the funding method set forth in the regulations and 
        discussed below.
4)  Forfeitures reduce employer contributions.
5)  Employee contributions are not used to fund the stated benefit.
6)  Disparity must satisfy the permitted disparity rules that apply to defined benefit plans (see Worksheet 5B for special rules).
The requirements of section 411(b)(1)(H) that prohibit a defined benefit plan from ceasing or reducing accruals on account of the participant’s 
attainment of any age generally also apply to a target benefit plan. (See Alert Guidelines 2A for a discussion of these rules). Thus, the 
uniform post-normal retirement benefits rule discussed in line XI.a. of Worksheet 5A may apply. Such benefits must be provided under 
the stated benefit formula, subject to any uniformly applicable service cap under the formula. Actuarial increases in the stated benefit for 
delayed retirement are impermissible.
The regulations contain a detailed formula for calculating the required employer contribution that must be followed by a target benefit safe 
harbor plan. Specialists should refer to the regulations when reviewing a target benefit plan for the actual step-by-step calculations, but the 
main steps and some important points to keep in mind are described below.
First, a theoretical reserve is calculated based on the stated benefit as of the date the employer’s required contribution for the current plan 
year is determined. The initial reserve for the participant’s first year of participation (or the first plan year taken into account under the stated 
benefit formula, if that is the current year) is zero.
(The theoretical reserve for the first plan year following any plan year in which the plan failed to satisfy this safe harbor is also zero. 
However, if the plan was adopted and in effect on September 19, 1991 and met the qualification requirements for target benefit plans under 
prior law, it may be allowed to take into account years of service for years in which this safe harbor was not met. In this case, the theoretical 
reserve as of the determination date for the last year before the plan satisfies this safe harbor is the excess, if any, of the actuarial present 
value of the stated benefit the employee is projected to have at NRA over the actuarial present value of future employee contributions 
required through NRA.)
The subsequent years’ reserves are the sum of the theoretical reserve for the prior year plus the required contribution for the prior year, 
increased, using a standard interest rate, for interest between the prior year determination date and the current year determination date.
Next, the actuarial present value of the participant’s fractional rule benefit under the stated formula is determined as of the current plan 
year’s determination date, using a standard interest rate and mortality table set forth in the plan and uniformly applied.
The required contribution for the current year is determined by amortizing the difference between the theoretical reserve and the fractional 
rule benefit on a level basis from the determination date for the current year and the determination date for the year in which the participant 
is projected to reach NRA.
Where the participant is at or past NRA, the required contribution is the difference between the actuarial present value of the stated benefit 
for the current year, using a straight life annuity factor based on the employee’s NRA (rather than attained age), and the theoretical reserve 
as of the determination date.
Required contributions must be limited or increased, if necessary, to comply with sections 415 and 416, respectively. For purposes of these 
calculations, interest rates between 7.5% and 8.5% are standard interest rates. The UP-84 mortality table is an example of a standard 
mortality table. 
1.401(a)(4)-8(b)(3)

III. Nondiscriminatory Compensation
Line a. If a design-based safe harbor plan bases allocations on compensation, it must use a definition of compensation that is nondiscriminatory 
under section 1.414(s)-1 of the regulations. (The requirement to use a nondiscriminatory definition of compensation would also apply in 
the case of the definition of compensation that a section 401(k) or 401(m) plan must use in its actual deferral percentage (ADP) or actual 
contribution percentage (ACP) test.) The regulations contain certain definitions that are automatically nondiscriminatory under section 414(s). 
A plan may use an alternative definition, provided the definition is reasonable, not designed to favor highly compensated employees, and 
that the average percentage of total compensation included for highly compensated employees as a group does not exceed the average 
percentage for nonhighly compensated employees by more than a de minimis amount. In addition, under certain circumstances a plan 
may use rate of compensation, imputed compensation, or prior-employer compensation under a definition of compensation that satisfies 
section 414(s). Section 414(s) and the accompanying regulations provide specific definitions of compensation that satisfy section 414(s). 
One of the definitions is compensation within the meaning of section 415(c)(3). See Explanation #6 for the full definition of compensation 
for section 415 purposes, (including other changes that are not reflected in the following summary).

Page 4                                                                         For applications submitted to conform to the 2020 RA List
The following definitions of compensation automatically satisfy section 414(s):
1)  Compensation within the meaning of section 415(c)(3). This definition of compensation includes elective deferrals defined in 
        section 402(g)(3) and amounts deferred under a section 125 cafeteria plan, section 132(f)(4), or under a section 457 plan. Under 
        this definition, a self-employed person’s compensation is earned income as defined in section 401(c)(2).
2)  Wages as defined in section 3401(a) plus all other compensation required to be reported by the employer under sections 6041, 
        6051 and 6052, or wages as defined in 3401(a), both determined without regard to any rules that limit wages based on the nature 
        or location of employment.
3)  A safe-harbor definition that starts with 1 or 2, but excludes all of the following: reimbursements or other expense allowances, 
        fringe benefits, moving expenses, deferred compensation, and welfare benefits. This safe harbor generally permits the following 
        definition to fall within the scope of section 414(s): Regular or base salary or wages, plus commissions, tips, overtime and other 
        premium pay, bonuses, and any other item of compensation includible in gross income not listed in the safe-harbor exclusions. If 
        this definition is used, any self-employed individual’s compensation is to be limited to earned income multiplied by the percentage 
        of nonhighly compensated employees’ total compensation (determined on a group basis) that is included under the plan definition.
4)  Under any of these definitions, the employer can elect to include or exclude elective contributions not includible in income, section 
        457(b) deferred compensation, and section 414(h)(2) pick-up contributions. If any of these are included (excluded), they must all 
        be included (excluded).
        1.414(s)-1

Line b. If the plan is using a definition of compensation permissible under section 415(c)(3), then it must define compensation for any self-
employed individual as earned income within the meaning of section 401(c)(2).
If the plan is using the alternative safe harbor definition that excludes certain expenses and other items or an alternative definition that 
requires a demonstration, then the terms of the plan must provide for an equivalent alternative definition for self-employed individuals, 
determined as follows.
The self-employed individual’s earned income (increased by elective contributions, if any of these are included in the plan’s alternative 
definition) is multiplied by the percentage of total compensation (including elective contributions, if any of these are included in the plan’s 
alternative definition) that is included for the group of nonhighly compensated common-law employees. (This calculation is to be performed 
consistent  with  the  rules  for  determining  whether  an  alternative  definition  of  compensation  is  nondiscriminatory,  except  that  highly 
compensated common-law employees are disregarded.)
The plan’s alternative definition may also limit the compensation of some or all self-employed individuals who are also highly compensated 
employees to a portion of the equivalent compensation. 
Specialists are reminded that plans may have multiple definitions of compensation (one for section 415 purposes, one for allocation 
purposes, etc.). It is only the plan’s administrable definition for purposes of providing allocations under the plan that must meet the section 
414(s) requirements.
