The Free Creditor Shield on Your 401(k) — and the Two Boundaries That End It

Retirement money is the largest single block of U.S. household wealth — $49.1 trillion at the end of 2025, about a third of all household financial assets. Hanging off that pool is a legal feature with real value that no brokerage statement prints: a qualified employer plan like a 401(k) is nearly untouchable by creditors. For an investor who carries a mortgage, credit-card or student debt, runs margin, or owns a business with liability risk, that shield has a monetary meaning. The useful question is where it begins and where it ends, because the answer determines how much of your savings a judgment or bankruptcy could actually reach.

The rule sits in ERISA, the 1974 law that governs employer plans — 401(k)s, 403(b)s, pensions, profit-sharing. Its anti-alienation clause says plan benefits can't be assigned or transferred, and the protection has no dollar ceiling: whether the account holds $100,000 or $10 million, the answer is the same. The Supreme Court confirmed the point in puts the money beyond the bankruptcy estate; outside bankruptcy, the same clause generally blocks an ordinary judgment creditor from levying the account.

None of that is absolute, and the exceptions are worth knowing because each maps to a claim that genuinely can reach the account: a qualified domestic relations order in a divorce can split the balance, and child-support and alimony orders can as well; the IRS can levy the account for unpaid federal taxes; and a federal criminal restitution order can empty it. Just as important is where the shield does not live — inside the plan only. The day a distribution lands in your checking account, it is ordinary money that a judgment creditor can garnish like any other.

The boundary that matters for most investors sits one account-type below the 401(k). IRAs are not governed by that ERISA clause. Inside bankruptcy, a traditional or Roth IRA is protected only up to an inflation-indexed cap — $1,711,975 for cases filed on or after April 1, 2025, raised from $1,512,350 and reset every three years. Under the federal exemption, money rolled over from an employer plan keeps an exemption of its own, beyond the cap, as long as it stays a separate rollover account; SEP and SIMPLE IRAs are treated like employer plans. Commingle your own contributions with that rollover money and the tracing — and with it the unlimited line — gets murkier.

Outside bankruptcy, an IRA has no federal shield at all, and state law is fifty different answers. Some states exempt the full balance regardless of amount, Texas and Florida among them; others cap the exemption, Nevada at $500,000; others protect only what a court decides is reasonably necessary for your support, as in California and Georgia. The same IRA, the same dollar amount, can be creditor-proof in Dallas and attachable in Reno. This is the piece that makes the routine rollover a real decision rather than an administrative formality: moving an old 401(k) into an IRA swaps an unlimited federal shield for a capped one governed by whichever state you happen to live in.

The account that surprises people most has no shield at all: an inherited IRA. In Clark v. Rameker (2014), the Supreme Court held that money inherited from someone else's retirement plan is not "retirement funds" under the Bankruptcy Code, so a trustee can reach it when the beneficiary files. A few states protect inherited IRAs anyway, but the federal default is nothing. Money you inherit is the least protected money in the retirement system — even though you will never see that fact at the moment you inherit.

Read as a value investor reads a balance sheet, this three-tier hierarchy is an asset on your personal ledger that sells at zero: it costs nothing, cannot be bought, and sets the worst case. The investor judgments follow directly.

First, the rollover: keeping an old employer plan where it is preserves the unlimited shield; rolling a large balance into a commingled IRA hands a creditor the excess above the cap. That is an unpaid-for downside in the most routine transaction in retirement finance, and the brokerage completing the rollover will not mention it.

Second, don't pay for what you already own. A large share of the "asset protection" industry — annuities, insurance riders, trust marketing — sells a version of the protection your 401(k) already provides for free. The paid version earns its fee only for people who outgrow the free one: cap-sized IRAs in low-protection states, large nonqualified assets, professional-liability exposure. For everyone else it is a fee without a feature.

Third, inherited money belongs on the unprotected side of the ledger when you size how much liability you can afford to carry, not in the column marked safe because it came out of a retirement plan.

Value investing conventionally asks what an asset would bring in a forced sale. For retirement savings, the forced-sale floor is set by one question, and the answer is printed nowhere on your statement: is the account an employer plan, an IRA, or an inherited one? Write down which of the three buckets each account sits in, and the part of your net worth a creditor could ever reach becomes a number you know rather than a fear. It is the rare balance-sheet exercise with a guaranteed payoff — the one asset in the portfolio that needs no multiple, earning check, or discount rate, because the law hands it to you at par.
