Is your multiemployer pension plan worth the risks and costs? Consider these reduced withdrawal liability options

August 7, 2025 / 5 min read

Employers considering withdrawal from multiemployer pension plans often face prohibitively expensive withdrawal liabilities, but many times they aren’t getting the full story. Alternate calculations and legislative relief could provide solutions.

Many of America’s 1,400 multiemployer pension plans are in varying states of financial distress. The American Rescue Plan Act of 2021 (ARPA) included funding for the Pension Benefit Guaranty Corporation (PBGC) to provide grants that will reduce underfunding in the nation’s most at-risk multiemployer pension plans. Employers who participate should consider the impact of the pension funding relief on their plans and evaluate if the revised costs of withdrawal will be outweighed by the benefits of continued participation.

A brief history of multiemployer pension plans

A multiemployer pension plan is a retirement plan created through an agreement between two or more employers, typically in the same or related industries, and the union that represents their employees. These multiemployer pension plans have provided advantages over the years by reducing the per-employee costs of administration through economies of scale. However, with industries seeing downturns in U.S. activity, many plans are now threatened by increasing liabilities at a time when the pool of workers available to fund them is decreasing. The resulting underfunding of some multiemployer pension plans has become so severe that Congress included billions of dollars in the ARPA COVID-19 relief bill to fund direct grants to the plans most in danger of running out of funds.

Multiemployer pension plan withdrawal liability

With Pension Benefit Guaranty Corporation (PBGC) premiums expected to increase and the long-term financial solvency of these plans in question, many employers who participate in them are considering whether to withdraw and invest in different retirement benefit options for their employees. In order to exit from an underfunded multiemployer pension plan, employers must pay a “withdrawal liability” equal to their share of the underfunding. In general terms, the amount of withdrawal liability an employer owes is the lesser of:

When employers ask their plan administrators about withdrawal, they’re typically told only that their withdrawal liability will be the share of underfunding. In today’s market, especially prior to the distribution of the ARPA grants by the PBGC, this cost could make withdrawal prohibitively expensive. Understanding the alternative calculation and working with the plan administrator to utilize it can make an exit much more affordable.

When employers ask their plan administrators about withdrawal, they’re typically told only that their withdrawal liability will be the share of underfunding.

What does ARPA do for multiemployer plans?

ARPA offers “special financial relief” (SFA) to multiemployer pension plans that meet one of the following four criteria:

Because these grants will reduce the underfunded amounts at the plans that receive them, they’ll also reduce the withdrawal liability calculated under the first method above. However, the best-case scenario for plans that do qualify for SFA will be an amount sufficient to pay 100% of benefits through the 2051 plan year.

In addition to pension funding relief, ARPA includes an increase in PBGC premiums for multiemployer pension plans. So, at a time when economic circumstances are already making it harder to keep up with funding requirements for these plans, it’s likely that this premium increase will result in higher administrative costs for employers who choose to remain in a multiemployer plan going forward.

Multiemployer pension plan withdrawal: Before you act, consider these three scenarios

When it comes to decisions about withdrawing from a multiemployer pension plan, employers need to understand how their plans fit into one of the following three classifications:

Ninety-eight multiemployer pension plans received Special Financial Assistance (SFA) under ARPA through October 2024. With so many variables to consider in the process of qualifying for and receiving SFA, it may still be difficult for some employers to calculate the impact that SFA relief has had on withdrawal liability. Many in the industry have been disappointed by this assistance and regard it as too inequitable, only kicking the can down the road without fixing the underlying multiemployer pension system.

It may still be difficult for some employers to calculate the impact that SFA relief has had on withdrawal liability.

As with any type of tax or employee benefit plan advice, affected employers should discuss their individual facts and circumstances with a knowledgeable advisor who is familiar with their situation.
