Conduit IRA

A conduit IRA is a traditional individual retirement account used exclusively to hold funds rolled over from an employer-sponsored retirement plan, such as a 401(k) or 403(b), before transferring them to a new employer's plan. It keeps rollover funds completely separate from personal IRA contributions, which is what makes it a "conduit." Think of it like a holding tank between two employer plans, keeping the water from one source clean and unmixed with anything else.

The conduit IRA concept predates current law, but it remains useful today for specific tax planning and creditor protection situations.

Why the Conduit IRA Was Created

Before the Economic Growth and Tax Relief Reconciliation Act of 2001 (EGTRRA), rollovers from a qualified plan into a new employer's 401(k) were only permitted if the IRA holding the funds had never been mixed with personal contributions. That strict non-commingling requirement made the conduit IRA a practical necessity for anyone planning to move retirement assets between employers through an IRA.

EGTRRA eliminated the commingling restriction for most rollover purposes, which reduced the legal necessity of maintaining a conduit IRA. However, several situations still justify the separate account structure.

Three Reasons to Still Use a Conduit IRA

No law requires you to segregate rollover funds in a conduit IRA today, but there are three circumstances where doing so remains advantageous.

Some Employer Plans Only Accept Rollover-Sourced Funds

Plan language varies. A future employer's 401(k) may only accept rollovers from funds that originated in a qualified plan and were never mixed with personal IRA contributions. If you commingled the rollover with your existing traditional IRA, you lose the ability to transfer those funds to that plan. Keeping them in a conduit IRA preserves your options.

Special Tax Elections Require a Conduit IRA

Workers who were born before 1936 and received a lump-sum distribution from a qualified plan may qualify for a 10-year forward averaging tax option or capital gains treatment on pre-1974 contributions. Using either of these special tax treatments requires eventually rolling the funds back into a qualified plan. To do that rollover later, the IRS requires the funds to have been maintained in a conduit IRA without commingling.

Creditor Protection in Bankruptcy Is Stronger

Under the Bankruptcy Abuse Prevention and Consumer Protection Act of 2005, assets in a qualified plan such as a 401(k) have unlimited protection from creditors in bankruptcy. Assets rolled into a contributory IRA are only protected up to the 2024 limit of $1,512,350. By keeping rollover funds in a conduit IRA separate from personal contributions, you maintain clear documentation to support a claim for the stronger plan-level creditor protection if you face bankruptcy.

The Non-Commingling Rule

A conduit IRA loses its special status the moment you make a personal contribution to it. There is no specific account type called "conduit IRA" at any financial institution. Any traditional IRA qualifies as long as it holds only funds that originated from a qualifying rollover and has never been mixed with regular contributions. If you add even one dollar of personal contributions, the account becomes a standard traditional IRA and the conduit protection is gone.

Setting Up a Conduit IRA

You do not need to label the account "conduit IRA" when opening it. You simply open a traditional IRA with a reputable custodian such as Fidelity, Vanguard, or Schwab and fund it exclusively through a direct rollover from your former employer's plan. Opt for a direct rollover, not a 60-day rollover, to avoid mandatory 20% withholding on the distribution. Once the funds are in the account, track them separately in your records and do not contribute anything else to that account.
