To borrow from yourself, you tap an asset you already own rather than going to an outside lender. Four sources actually work: a workplace retirement plan such as a 401(k), 403(b), or 457(b); the cash value of a permanent life insurance policy; a certificate of deposit or savings account pledged as collateral; or securities held in a taxable brokerage account. Each has its own dollar limits, repayment rules, and tax traps, and the right choice depends on which assets you hold, how fast you need cash, and whether you can stick to a repayment schedule.
One boundary to clear up first: you cannot borrow from a traditional or Roth IRA. The IRS treats a loan from an IRA as a prohibited transaction, and the consequence is unusually harsh. The entire account loses its tax-advantaged status as of January 1 of that year, the full balance is treated as a taxable distribution, and if you are under 59½ the 10% early withdrawal penalty applies on top.1Internal Revenue Service. Retirement Topics – Prohibited Transactions There is no cure. Putting the money back does not undo it. The statute names lending between a plan and a disqualified person (which includes you) as prohibited.2Office of the Law Revision Counsel. 26 U.S. Code 4975 – Tax on Prohibited Transactions
Retirement Plan Loans
Employer-sponsored plans like 401(k)s, 403(b)s, and 457(b)s can permit participant loans, but the plan document has to allow it. Not every plan does, so check your Summary Plan Description before you count on this option.
Federal tax law caps the loan at the lesser of $50,000 or 50% of your vested balance.3Office of the Law Revision Counsel. 26 U.S. Code 72 – Annuities; Certain Proceeds of Endowment and Life Insurance Contracts – Section: (p) Loans Treated as Distributions There is a floor for smaller accounts: if your vested balance is under $20,000, you can borrow up to $10,000 even though that exceeds 50%.
The $50,000 cap has a wrinkle that catches people out. It is reduced by the highest outstanding loan balance you carried in the previous 12 months, minus what you currently owe. If you borrowed $40,000 last year and have paid it down to $15,000, your new maximum is $25,000, not $50,000. The rule blocks people from cycling repeatedly through the full limit. You can carry more than one loan at a time from the same plan as long as the combined balance stays within the caps, though many plans set stricter internal limits, minimum loan amounts, or origination fees.4Internal Revenue Service. Retirement Plans FAQs Regarding Loans
The interest rate is typically prime plus a point or two, set by the plan administrator and usually fixed for the term. You pay that interest back to your own account, which softens the sting. But the dollars you use to repay have already been taxed, and they will be taxed again when you eventually withdraw them in retirement.
General-purpose loans must be repaid within five years, in substantially level payments made at least quarterly.3Office of the Law Revision Counsel. 26 U.S. Code 72 – Annuities; Certain Proceeds of Endowment and Life Insurance Contracts – Section: (p) Loans Treated as Distributions Most plans handle this through payroll deduction, which keeps you on schedule but also reduces your take-home pay for the duration. If the loan finances a primary residence, the five-year cap does not apply and the plan can allow a longer term, though level amortization is still required.5Internal Revenue Service. Retirement Topics – Plan Loans No deferring payments, no balloon at the end.
Some plans require spousal consent, particularly defined benefit plans and older 401(k)s subject to joint-and-survivor annuity rules. The consent typically has to be witnessed by a plan representative or a notary.6Internal Revenue Service. Fixing Common Plan Mistakes – Failure to Obtain Spousal Consent Skipping it when required creates compliance problems for the plan and complications for you.
When a Retirement Plan Loan Becomes Taxable
The loan stays tax-free only if you follow the repayment rules exactly. Two situations flip it into a taxable event.
The first is missed payments. If you stop paying while still employed, the outstanding balance (or the defaulted portion) becomes a “deemed distribution,” and you owe income tax on it for the year of the default.7Internal Revenue Service. Plan Loan Failures and Deemed Distributions Under 59½, tack on the 10% early withdrawal penalty.8Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions The nastiest part: a deemed distribution does not cancel the loan. You are taxed as if you received the money, but the plan can still require repayment on the original terms.
The second is job separation. Quit, get laid off, or retire with a balance outstanding, and most plans accelerate the loan, requiring full repayment within a short window. If you cannot pay, the remainder is treated as a plan loan offset and reported on Form 1099-R. You can dodge the tax by rolling the offset amount into an IRA or another eligible plan, but you have to come up with the cash from elsewhere. The rollover deadline is your federal income tax filing due date, including extensions, for the year of the offset.9Internal Revenue Service. Plan Loan Offsets Miss it and the full balance is taxable income, plus the 10% penalty if you are under 59½ (or under 55 in the year you separated).8Internal Revenue Service.

Life Insurance Policy Loans
Permanent policies (whole life, universal life, variable universal life) build cash value you can borrow against without surrendering the policy. Term life has no cash value and offers nothing to borrow.
The mechanics are simple. Request a current cash value statement, complete a loan form with your policy number and ID, and pick between a fixed or variable rate. Your maximum is roughly your accumulated cash value minus any surrender charges. There is no credit check, no income verification, and no required repayment schedule. That flexibility is the appeal, and it is also the danger.
How Policy Loans Quietly Go Wrong
If you do not pay the interest, it is added to the loan balance. That larger balance accrues more interest. Compound long enough and a modest loan can eat most of your cash value.
Once the loan balance reaches the cash value, the insurer lapses the policy to satisfy the debt. You lose the death benefit and can owe taxes on the gain even though you never received cash. Watch out too for the automatic premium loan provision common on these policies: if you miss a premium, the insurer borrows from cash value to cover it, adding to your balance and pushing you closer to lapse.
Tax Risks
Under normal circumstances a policy loan is not a taxable event. Two situations change that.
The first is a modified endowment contract. If a policy is funded too aggressively (failing the 7-pay test by taking in more premium than allowed during the first seven years), the IRS reclassifies it as a modified endowment contract.10Office of the Law Revision Counsel. 26 U.S. Code 7702A – Modified Endowment Contract Defined Loans from a MEC are taxable distributions with gains taxed first: income tax on the growth before any part of the loan is treated as a return of premium.11Office of the Law Revision Counsel. 26 U.S. Code 72 – Annuities; Certain Proceeds of Endowment and Life Insurance Contracts – Section: (e)(10) Treatment of Modified Endowment Contracts Under 59½, a 10% penalty applies. Your insurer tests the policy at issue, but if you made large additional payments or exchanged an older policy, ask before you borrow.
The second is the lapse tax bomb, which snares people who ignore an outstanding loan until the policy terminates. When a policy lapses, the IRS calculates your taxable gain as the full cash value minus your cost basis (total premiums paid). The loan balance does not reduce the gain. It only reduces the cash you actually receive.
Say your policy has $105,000 in cash value, you paid $60,000 in premiums, and you owe $100,000 on a policy loan. When the policy lapses, the insurer uses the cash value to pay off the loan and hands you $5,000. Your taxable gain is $45,000 ($105,000 minus $60,000). You can owe several thousand dollars in tax on a $5,000 check. Tax courts have upheld this treatment.
Loans Secured by a CD or Savings Account
You can pledge a certificate of deposit or savings account as collateral for what banks often call a passbook or CD-secured loan. The rate is usually a point or two above what your deposit earns. Because your money is sitting right there as collateral, this is among the cheapest borrowing available.
To set it up, provide the account number, current balance, and a recent statement showing no other liens. Loan-to-value ratios are high, often 80% to 100% of the deposit. If you pledge a CD, the loan term generally cannot extend past the CD’s maturity.
The legal backbone is a control agreement under Article 9 of the Uniform Commercial Code.12Legal Information Institute. U.C.C. – Article 9 – Secured Transactions (2010) You grant the lender a security interest in the deposit, and you cannot withdraw the pledged funds until the loan is paid off and the lien released. When the pledged account is held at a different institution from the lender, a three-party control agreement is required so the holding bank acknowledges the lender’s claim and freezes your access.13Legal Information Institute. U.C.C. 9-304 – Law Governing Perfection and Priority of Security Interests in Deposit Accounts Same-institution borrowing is far simpler.
If you default, the bank does not need a court order. The control agreement (and often your original account agreement) gives it the right to offset your deposit against the unpaid balance, sometimes without advance notice. The bank debits your account, satisfies the debt, and returns any remainder. The worst-case outcome is losing the savings you already set aside as collateral.
Margin Loans and Securities-Based Lines of Credit
Stocks, bonds, and funds in a taxable brokerage account can back a margin loan or a securities-based line of credit. The broker lends you cash against your portfolio, and you can use the money for almost anything, with no fixed repayment schedule in most cases.
Federal Reserve Regulation T caps the initial loan at 50% of the value of eligible securities.14FINRA. Margin Regulation After that, FINRA’s maintenance margin rule requires your equity to stay above 25% of the portfolio’s current market value.15FINRA. 4210. Margin Requirements Many brokerages set house requirements higher than the 25% floor.
The risk is real and immediate. When the portfolio drops, your equity can fall below the maintenance threshold, and the broker issues a margin call. You either deposit more cash or securities within a tight window (often just a few days) or the broker liquidates positions to bring the account back into compliance. The broker can sell without asking, and does not have to sell the holdings you would prefer to part with.14FINRA. Margin Regulation A forced sale in a downturn locks in losses you might otherwise have waited out.
Interest rates vary by broker and loan size and are usually tied to a benchmark rate. Unlike a retirement plan loan, the interest goes to the brokerage, not back to you. Treat margin as short-term financing and keep the borrowed amount well below your maximum so a market swing does not trigger a call.
Funding Speed and Repayment
Time to cash varies widely by asset. Retirement plan loans typically fund within a few business days to two weeks through a third-party custodian. Life insurance policy loans often fund within a week because the insurer already holds the policy and its cash value. Deposit-secured loans and margin loans are usually the fastest, sometimes within 48 hours, because the collateral is already in the lender’s hands.
Repayment structures differ just as much. Retirement plan loans generally repay through automatic payroll deduction, which keeps you compliant but leaves no room to pause without triggering a default. Life insurance policy loans have no required schedule at all, which sounds ideal until compounding interest catches up. Deposit-secured loans usually require monthly payments per your loan agreement. Margin loans typically require no scheduled payments, but interest accrues daily and the lender can call the loan whenever your collateral value slips.
Keep every statement, confirmation, and repayment record. For a retirement loan, the paper trail proves the loan was repaid and prevents the plan from reporting a phantom distribution years later. For a life insurance loan, tracking the balance against your cash value is the only way to see the lapse warning coming before it arrives with a tax bill attached.
