Updated August 6, 2026. Quick answer: two rules govern TSP loans that participants routinely get wrong, and they point in opposite directions. Your spouse must consent before you can take a loan — but your spouse does not have to consent, or even be told, when you name a beneficiary. And if you die with a loan outstanding, nobody is allowed to repay it, not even your estate.
The consent asymmetry inside one plan
5 C.F.R. §1655.13(a)(3) makes loan approval conditional on the fact that “[t]he spouse of a FERS or uniformed services participant has consented to the loan” — with an exception where the spouse’s whereabouts are unknown or exceptional circumstances make consent inappropriate.
Set that beside the designation rule: a beneficiary “may be designated without the knowledge or consent of that beneficiary or the knowledge or consent of the participant’s spouse” (§1651.3(b)) — the beneficiary rules in full.
So the plan requires a spouse’s signature to borrow your own money, and requires nothing at all to redirect the entire account away from them at death. That is not an inconsistency a reader can reason their way to; it is simply what the two regulations say, and knowing it is the difference between assuming you are protected and checking.
Dying with a loan outstanding
When a participant dies with an unpaid loan, the balance is settled by a loan offset — the outstanding amount is treated as distributed from the account. Under §1655.15, the record keeper “will report the distribution to the Internal Revenue Service as income for the year in which it occurs.”
Then comes the sentence worth reading twice. “Neither the estate nor any other person, including a beneficiary, may repay the loan of a deceased participant, nor can the funds be returned to the TSP.”
There is no cure. An executor who arrives with a cheque cannot undo it; a beneficiary who would rather keep the account whole cannot buy the loan back. The offset happens, the taxable income lands, and the account is permanently smaller by that amount. It is one of the few money problems in this area with no remedy at all after the fact — which makes before the only place to act.
What follows from that
The practical reading is narrow and worth stating plainly. An outstanding TSP loan is an unhedged liability against your beneficiaries, payable in tax, in a year they do not choose. If the account is a significant part of what you intend to leave, the loan balance is the first thing to look at — not the investment mix.
Two related pages: what the account does after death and who receives it — the inherited-TSP rules — and, if a divorce is in the picture, note that a court order can block loan processing entirely: §1655.13(a)(2) conditions approval on the loan not being prohibited by the court-order provisions — how TSP divorce orders work.
Leaving federal service: separation is the deadline
While you are employed, repayment is not optional and not yours to pause. §1655.14(a): loan payments “must be made through payroll deduction”, and once they begin “the employing agency cannot terminate the payroll deductions at the employee’s request” unless the TSP instructs it to.
Separation is what changes the position, and it is a hard cut-off. Where a loan has already been taxed, §1655.15(a)(2) allows a participant to repay it in full “up until the time he or she separates from Government service.” Separation closes that door. Note also that taxation alone does not cancel the debt — “[l]oan taxation does not relieve a participant of his or her obligation to repay the taxed loan amount.”
And if it is not repaid, §1655.15(a)(3) states the two consequences plainly: the account balance “will be permanently reduced”, and the taxed loan “will count as one of the two loans the participant is permitted per account and is treated as an outstanding loan balance when calculating the participant’s maximum loan amount.” It keeps costing you after it has been taxed — once in the permanent reduction, again in the borrowing capacity it continues to occupy.
So the two deadlines in this page are different in kind. Separation ends your ability to cure a taxed loan. Death ends everybody’s — and the death rule is the harsher of the two, because at separation you can still act.

5 C.F.R. §§1655.13, 1655.14 and 1655.15 (Federal Retirement Thrift Investment Board, Part 1655 — Loan Program), and §1651.3(b) for the designation contrast, read at the Legal Information Institute on 2026-08-06. Quotations are from the regulation text. We cite the regulations rather than the TSP’s own booklets because tsp.gov did not serve us, and because the regulations are the operative law in any event.
Honest gap, now closed. This page shipped covering only spousal consent and death, and said plainly that we had not read the separation rule to our standard. It has since been read at §§1655.14 and 1655.15(a) and is published above. What remains uncovered: the mechanics of loan reamortisation, the active-duty suspension rules, and the detail of how IRC §72(p) applies to offsets — all referenced in Part 1655 and none read here.
