Can I borrow against my 401k?

It’s a trick question: the 401k vernacular gets a little slippery on the distinctions among prepositions, which is the syntactic way of saying “from” and “against” often mean exactly the same thing when you inquire about the opportunity to “borrow against a 401k.” 

Very technically “borrow against” ought to mean “use as collateral,” and it would imply that you want money from a bank or credit union, putting up your retirement account as security for the loan.  Too technical it seems.

                If you query “borrow against 401k” on any search engine, you will find millions of results for your query, but the substance of all the discussions actually focuses on borrowing from your 401k: how do you take a loan from your retirement account?  Is it a good idea to take a loan from your retirement savings?  Under what circumstances can you do it, and what price do you pay for the expedience of borrowing money from yourself?

                And among these millions of ostensible answers to your perfectly reasonable question, “Can I borrow against my 401k?” you never will find an answer to the question of using it as security for a loan.  Even when the 401k pundits use the word “collateral,” they still don’t get to the point.

                We have some understanding and empathy for the folks who cannot take the question, “Can I borrow against my 401k?” as literally as it deserves.  The Internal Revenue Code, the legal authority for all things 400 and above, never explicitly addresses the question, so you have to work by inference and surmise.

So, can I borrow against my 401k?

Under certain circumstances, and always as a last resort, you may borrow from your 401k. But, no, you cannot borrow against your 401k in the sense that you would use it as security for a new loan. 

                The law does not expressly prohibit using the 401k as security, but it limits who may attach the funds in your retirement account.  If you borrowed against your 401k, the bank or lending institution would have to exercise it authority to attach, garnish, levy, or lay claim to those funds; and the law does not grant them that authority, Only the Federal government can “invade” your 401k, and it can take your retirement funds only as payment for delinquent income tax obligations.  The Feds can justify this intrusion on the idea that they are recovering the money they originally exempted from taxes; if they had the authority to grant the exemption, and then they have the corollary authority to rescind the exemption. 

Only you and the Feds can mess with the money in your 401k.
