Minimum funding and contribution limits are different rules. Minimum funding is an employer’s plan-level obligation under Internal Revenue Code (IRC) §§412 and 430. It is calculated from the plan’s actuarial liabilities, expected benefit accruals, adjusted assets and applicable amortization charges. A contribution limit, by contrast, is a statutory ceiling on the benefit an individual participant may receive under IRC §415(b). For 2026, that defined-benefit annual dollar ceiling is $290,000, subject to the separate high-three-year average compensation test.
Consequently, a plan may owe a minimum contribution even when every participant is far below the §415(b) ceiling. Conversely, keeping promised benefits under the §415(b) limit does not prove that the employer has met its §430 funding obligation.

The two rules answer different questions
IRC §412 establishes minimum funding standards for qualified defined-benefit plans. IRC §430 supplies the detailed minimum-required-contribution rules for most single-employer defined-benefit plans. These provisions ask: How much must the employer contribute to keep the plan funded under the statutory actuarial standard?

What goes into an IRC §430 minimum required contribution
The exact amount is an actuarial calculation. The IRS explains that contributions are based on what is needed to provide “definitely determinable benefits” and that actuarial assumptions and computations are required. The following components are the building blocks an enrolled actuary uses.
Target normal cost
Target normal cost is the present value of benefits expected to accrue during the plan year. The calculation also includes expected plan administrative expenses and reduces the result by expected mandatory employee contributions. It represents the cost of benefits earned during the current year, rather than the cost of benefits earned in prior years.
Because it is a present-value calculation, target normal cost changes when the actuary changes the discount rate, salary-growth assumption, retirement pattern, turnover expectation, mortality table or other permitted assumption. A plan with the same benefit formula can therefore have a different target normal cost in different years.
Funding target
The funding target is the present value of benefits accrued or earned as of the beginning of the plan year. It measures the liability for benefits already earned, not merely the current year’s accruals. The actuary projects the benefits under the plan document and discounts the expected payments back to the valuation date using the assumptions required for the plan.

The funding target is compared with the plan’s adjusted assets. That comparison determines whether a shortfall exists and whether shortfall amortization charges are needed.
Plan assets and statutory balance adjustments
The assets used in the statutory calculation are not always the same figure shown on an investment statement. Section 430 requires actuarial valuation of plan assets and adjustments for items such as the prefunding balance and the funding-standard carryover balance. Elections to use or waive those balances can affect the amount that must be contributed.

An employer should not assume that an amount deposited into the trust automatically equals the amount credited for §430 purposes.
Shortfall and waiver amortization charges
If adjusted assets are below the funding target, the plan generally has a funding shortfall. Section 430 uses statutory amortization charges to spread that shortfall over the permitted period. A waiver amortization charge can also apply when the plan has received a funding waiver and the statutory repayment schedule is still running.
In a simplified description, the minimum required contribution starts with target normal cost and adds the applicable shortfall and waiver amortization charges. The actuary then applies required statutory adjustments, including available balances and contributions made during the year. The result is not a fixed percentage of payroll and cannot be inferred from the participant benefit limit.

When assets meet or exceed the funding target
When adjusted assets meet or exceed the funding target, the shortfall component may disappear and excess assets can reduce the required contribution. The reduction is subject to the statutory floor and other §430 rules; it does not necessarily reduce the obligation to zero. Target normal cost and any applicable statutory adjustments still have to be considered.
Actuarial assumptions and 2026 mortality tables
Discount rates, mortality, expected retirement ages, salary increases, turnover and other assumptions change the present value of liabilities. IRS Notice 2025-40 specifies updated static mortality tables for valuation dates during 2026. The actuary must use the table and assumptions applicable to the plan’s valuation and legal requirements. A change in the mortality table can increase or decrease the measured funding target even if the plan document and participant census are unchanged.
Step-by-step: how an actuary determines the minimum
- Confirm the plan and valuation year. Identify whether the plan is a single-employer defined-benefit plan subject to §430, the plan year, valuation date and benefit formulas in the governing document.
- Build and validate the participant census. The actuary needs active, retired, terminated-vested and beneficiary data, including birth dates, service, compensation, accrued benefits and expected payment forms. Missing or stale data can distort both normal cost and funding target.
- Select the required assumptions and tables. Apply the permitted discount-rate structure, demographic assumptions and the mortality table required for the valuation date. For 2026 valuation dates, Notice 2025-40’s updated static mortality tables are part of this review.
- Calculate target normal cost. Project benefits expected to accrue in the plan year, add expected plan expenses and subtract expected mandatory employee contributions.
- Calculate the funding target. Determine the present value, at the beginning of the plan year, of benefits already accrued.
- Value and adjust plan assets. Determine the statutory actuarial asset value and account for prefunding and funding-standard carryover balances, including any permitted election affecting their use.
- Determine amortization charges. Compare adjusted assets with the funding target and calculate any required shortfall or waiver amortization charges.
- Apply statutory credits, prior contributions and the floor. Account for contributions already made, interest adjustments and the minimum floor. The actuary then issues the minimum required contribution for the year and the installment schedule.
This workflow explains why a plan sponsor cannot calculate the legal minimum by multiplying a participant’s promised pension by a simple percentage. The liability is a present-value estimate for the entire plan, and every assumption and balance can affect the result.
2026 defined-benefit and related contribution limits
The most commonly requested “2026 defined-benefit limit” is the IRC §415(b)(1)(A) annual benefit limit. For 2026, the indexed dollar amount is $290,000, according to the Internal Revenue Service’s 2025 annual limit guidance. Section 415(b) generally limits a participant’s annual defined-benefit payment to the lesser of 100% of the participant’s high-three-year average compensation or the applicable indexed dollar amount.
| Rule | 2026 amount | What it governs | Source and qualification |
|---|---|---|---|
| IRC §415(b)(1)(A) | $290,000 | Annual defined-benefit payment ceiling, subject also to the high-three-year average compensation test | Internal Revenue Service, 2025 guidance; applies for 2026 |
| IRC §415(c)(1)(A) | $72,000 | Annual additions limit for defined-contribution plans | Internal Revenue Service, 2025 guidance; this is not the defined-benefit limit |
| Qualified-plan compensation limit | $360,000 | Compensation limit used in certain qualified-plan contribution calculations | Internal Revenue Service, 2025 guidance; applicability depends on the specific plan rule |
The $72,000 figure belongs to the defined-contribution annual-additions rule. It should not be substituted for the $290,000 defined-benefit limit. The $360,000 compensation figure is also not a pension-payment ceiling; it is a compensation input for particular qualified-plan calculations.

How the two rules operate together
A plan can owe funding with modest participant benefits
Suppose no participant is close to the $290,000 §415(b) ceiling. The plan can still have a large funding target because many participants have accrued benefits, because the workforce is aging, because assumptions changed or because investment losses reduced assets. The employer’s §430 obligation is driven by that plan-wide liability and asset comparison, not by proximity to the individual payment cap.
A plan can satisfy §415(b) and still be underfunded
A benefit formula may be designed so that every participant’s annual payment remains below the §415(b) ceiling. That design decision does not establish that the trust holds enough assets under §430. Funding compliance requires the annual actuarial calculation and timely contributions.
A plan can be well funded while a benefit formula needs a §415(b) check
Strong assets do not permit the plan to pay an individual more than the statutory benefit limit. The administrator must test the participant’s annual benefit against both the indexed dollar amount and the high-three-year average compensation rule before payment.
Do not use one figure as a proxy for the other
- Do not use $290,000 as a funding target or as a contribution percentage.
- Do not infer the minimum employer contribution from a participant’s annual pension.
- Do not treat a favorable asset balance as permission to ignore the §415(b) payment ceiling.
- Do not treat compliance with §415(b) as evidence that quarterly §430 installments were paid.
When and how minimum contributions are paid
Minimum required contributions generally are paid in quarterly installments. For a calendar-year plan, the listed installment dates are:
Recommended Free Tools
| Installment | Due date |
|---|---|
| First | April 15 |
| Second | July 15 |
| Third | October 15 |
| Fourth | January 15 of the following year |
The dates above are for a calendar-year plan; a different plan year produces a different calendar. Confirm the exact due dates with the plan’s actuary and administrator rather than assuming the calendar-year schedule applies.

Late installment amounts can accrue interest. IRS guidance also identifies excise-tax exposure under IRC §4971 for unpaid minimum required contributions. A sponsor should monitor each installment, the amount credited to the trust, the deposit date and any required interest adjustment.
What happens if the employer misses the minimum
Interest and excise-tax exposure
An unpaid or late minimum required contribution can produce interest and an excise tax under §4971. The longer the shortfall remains outstanding, the harder it is to reconcile the trust’s actual deposits with the amount required under the actuarial certification.
Administrative and compliance work
The sponsor may need the actuary to recalculate the unpaid amount with interest, determine whether later installments were affected and prepare corrected funding documentation. The plan administrator, trustee and tax adviser may each have separate reporting or correction responsibilities.

Benefit-payment implications
Funding failure and a §415(b) excess are different problems. An unpaid minimum contribution concerns the plan’s funding status. A payment above the §415(b) ceiling concerns the participant’s benefit. Each requires its own analysis and correction path; fixing one does not automatically fix the other.
Practical checklist for plan sponsors
- Identify the plan year and statutory valuation date.
- Give the actuary a complete, reconciled participant census before the valuation.
- Confirm which assumptions and mortality tables apply to the valuation date, including the 2026 tables specified by Notice 2025-40.
- Request a written breakdown of target normal cost, funding target, asset value, carryover and prefunding balances, and each amortization charge.
- Record any contributions already deposited for the plan year and verify how the actuary credits them.
- Calendar every quarterly installment and retain evidence of the deposit date and amount.
- Ask whether an asset balance creates a permissible reduction and what statutory floor remains.
- Separately test each participant’s projected annual benefit under §415(b), including the high-three-year average compensation limit.
- Escalate late deposits, data errors, assumption changes or benefit amendments promptly; waiting until the annual filing can increase the correction burden.
Why professional actuarial help is usually necessary
Publication 560 (2025) warns: “Determining the amount needed to satisfy the minimum funding standard for a defined benefit plan is complicated, and you should seek professional help to meet these contribution requirements.” That warning reflects the interaction of present-value calculations, statutory asset adjustments, amortization schedules, mortality tables, installment timing and interest.
An enrolled actuary can calculate the §430 amount and explain the effect of a balance election or assumption change. A tax adviser can address §4971 exposure and reporting. The plan administrator should coordinate both analyses with the separate §415(b) benefit-limit test.
Bottom line
For 2026, $290,000 is the indexed IRC §415(b) annual defined-benefit payment limit, not the minimum an employer must contribute. The minimum contribution for a §430 plan is an actuarial amount built from target normal cost, the funding target, adjusted assets and applicable shortfall or waiver amortization charges. Treat the funding calculation and the participant benefit ceiling as two independent compliance tests, and meet the quarterly deadlines that apply to the plan year.
