Qualified retirement plans are funded by contributions from employers and/or
employees. These contributions are subject to a number of annual
limitations. In defined benefit plans, some of the limits are based on the
maximum benefit that can be provided at retirement. Adherence to these
limitations is important since the qualification of the plan is at stake.
Recently released regulations to Internal Revenue Code (IRC) section 415
have made changes that impact plan limits effective for plan years beginning
after June 30, 2007. Let’s take a close-up look at plan limitations and the
manner in which they are calculated.
Contribution and benefit limits are based in part upon participants’
compensation. The maximum compensation that can be considered for plan
purposes for plan years beginning in 2007 is $225,000. Generally,
compensation for limitation purposes must include all forms of remuneration
paid to an employee. Salary deferrals to qualified plans under any of the
following IRC sections must also be included: 401(k), 403(b), 457, 125
(cafeteria plans) and 132(f)(4) (transportation fringe benefit plans).
Compensation also includes deemed payments to disabled participants.
Under the new regulations, compensation paid after an employee’s
termination date (“post-severance compensation”) will not be included unless
(1) it is paid within 2½ months of employment termination or by the end of
the limitation year, if later, and (2) it would have been paid had the
employee remained employed.
For partners and self-employed owners of unincorporated businesses,
compensation means net earnings with certain adjustments. Net earnings are
reduced by 50% of self-employment tax as well as employer contributions to
retirement plans made on behalf of the partner or self-employed individual.
Salary deferrals are not deducted from net earnings for limitation purposes.
In S corporations, only income that is distributed to the owner as wages,
subject to social security taxes, can be used for retirement plan purposes.
Pass-through income is not included.
The measuring period for contribution and benefit limitations is called
the “limitation year” and is usually the plan year. However, a different
12-month period may be elected by the employer. Where a change in the
limitation year results in a short plan year of less than 12 months, the
annual additions, annual benefit and compensation limits are pro-rated
accordingly. Under the new regulations, this now applies to plans that
terminate prior to the last day of the limitation year.
IRC section 415(c) provides the maximum “annual additions” that can be
allocated to an individual’s account in a defined contribution plan (profit
sharing, 401(k), etc.). Annual additions include:
- Employer contributions;
- Employee contributions (deductible or
- Forfeitures allocated to the participant’s account.
The annual additions limit is the lesser of:
- 100% of a participant’s compensation, or
- A specified dollar amount–for limitation years ending in 2007, the
dollar limit is $45,000.
Contributions to a defined benefit plan are actuarially calculated to
fund the retirement benefits provided under the plan. Under IRC section
415(b), the annual benefit limit at normal retirement ages between 62 and 65
is the lesser of:
- 100% of a participant’s high consecutive
three-year average compensation, or
- A specified dollar amount–for limitation years ending in 2007, the
dollar limit is $180,000.
The limit is actuarially adjusted for retirement ages above 65 and below
For limitation purposes, all defined contribution plans of an employer
are treated as one plan, and all defined benefit plans of an employer are
treated as one plan.
Plans sponsored by related employers must also be aggregated for
limitation purposes, including the compensation from such related employers.
A related employer can be a controlled group of businesses
(parent-subsidiary or brother-sister groups) or an affiliated service group.
Controlled groups are connected by stock ownership rules, while affiliated
service groups are connected through business operations, including the
management of the businesses and/or the services provided.
A section 403(b) plan will not be combined with other plans of the same
employer because a 403(b) plan is considered to be maintained by each
individual employee for section 415 purposes. However, if a 403(b) plan
participant owns more than 50% of a business, then that business is
considered to be the sponsor of the owner’s 403(b) plan for section 415
purposes. As a result, any other plan sponsored by such business must be
combined with the owner’s 403(b) plan for limitation purposes.
Under the new regulations, plans of a predecessor employer and plans of a
formerly related employer must also be aggregated for section 415 purposes.
Employees are allowed to make salary deferrals to section 401(k), 403(b)
and 457 plans. The annual deferral limit into these plans is the lesser of:
- 100% of compensation, or
- $15,500 for the 2007 calendar year ($10,500 for SIMPLE plans).
Note that the deferral limit is not based on the plan year but on the
calendar year. Where an employee participates in two or more salary deferral
plans of different employers in a calendar year, it is the employee’s
responsibility to make sure he does not exceed the annual limit. If so, he
must take steps to initiate the necessary refunds by April 15th of the
Participants who are considered “highly compensated employees” (generally
5% owners and those earning over $100,000) may be subject to an additional
deferral limit based on the plan’s average deferral percentage (ADP) test.
Individuals age 50 and over as of the last day of the calendar year may
be eligible to make additional deferrals into their salary reduction plans,
if permitted under the terms of the plan. These “catch-up” contributions are
limited to $5,000 for 2007 ($2,500 for SIMPLE plans). Catch-up contributions
are defined as deferrals in excess of any one of the following:
- The annual dollar deferral limit ($15,500 for
- The annual additions limit ($45,000 for 2007);
- The ADP test limit; or
- Any plan imposed deferral limit.
Catch-up contributions are not counted when determining if other
limitations have been met but actually serve to extend these limitations.
Consequently, in salary deferral plans, the annual additions limit is
extended from $45,000 to $50,000 and the deferral limit is extended from
$15,500 to $20,500 for participants age 50 and over.
One advantage of a qualified plan is that the employer contributions to
the plan are tax deductible. Separate deduction limits apply to defined
benefit plans, defined contribution plans and a combination of the two.
Contributions that are not deductible are subject to a 10% excise tax.
The Pension Protection Act of 2006 (PPA) made a number of changes to the
contribution deduction rules.
For defined contribution plans, the deduction limit is 25% of the total
plan compensation of all eligible participants. Salary deferrals are not
counted towards the 25% limit.
For defined benefit plans, the contributions that are necessary to
satisfy the plan’s actuarial funding requirements can be deducted, even if
they exceed 25% of eligible compensation. PPA liberalized the funding rules
for defined benefit plans which significantly increased deductible
contribution opportunities in an attempt to improve the funding status of
PPA changed the deduction rules for employers who maintain a combination
of defined benefit and defined contribution plans. The previous deduction
limit for combined plans was the greater of 25% of compensation or the
amount necessary to fund the defined benefit plan. Where the defined benefit
plan funding exceeded the 25% limit, only elective deferrals could be
contributed to a defined contribution plan.
As of 2006, employers who sponsor a defined benefit plan can also
contribute and deduct up to 6% of compensation for the same employees in a
defined contribution plan even if the total contributions exceed 25% of
compensation. The new rule allows a defined benefit plan sponsor to
establish a safe harbor 401(k) plan, if desired. This would allow all
participants to defer up to the maximum dollar amount because ADP
nondiscrimination testing would not be required.
Example: Company X sponsors both a
defined benefit and a 401(k) plan for its employees. The required annual
contribution for the defined benefit plan is $100,000, which is
approximately 30% of eligible compensation. Prior to PPA, contributions to
the 401(k) plan would be limited to salary deferrals since they are not
part of the deduction limit calculation, and no other employer
contributions to the plan could be deducted. But as of 2006, the employer
can make and deduct a match and/or nonelective contribution of up to 6% of
eligible compensation into the 401(k) plan.
If a safe harbor notice was distributed to participants by December 1,
2006, the plan could become a safe harbor 401(k) plan for 2007, since 6%
is more than enough to satisfy either the 3% nonelective or the maximum 4%
match safe harbor contribution requirements.
As of 2008, defined benefit plans that are subject to the federal Pension
Benefit Guaranty Corporation (PBGC) insurance program can be completely
ignored in determining deduction limits for combinations of plans. That
means an employer will be able to deduct up to 25% of eligible compensation
in a defined contribution plan in addition to the contribution that is
necessary to fund a defined benefit plan, regardless of the amount.
It is important to make certain each year that your plan’s contributions
and/or benefits are within the allowable limits. Dollar limits are adjusted
periodically for cost-of-living and should be reviewed on an annual basis.
New regulations have made changes in the way certain limitations are
calculated. Recent increases in contribution deduction limits have provided
new opportunities for retirement planning.
