What Is Infinite Banking? A Plain Answer for High-Income Families

By Kevin Luu, Co-Founder and Chief Learning Officer. Reviewed on 2026-09-30.

Infinite banking is a way of using a dividend-paying whole life insurance policy as a personal source of credit. You pay large premiums to build the policy’s cash value, then borrow against that cash value instead of borrowing from a bank, and repay the policy on your own schedule. It is a real contract with real tax features, but it is an insurance purchase, not a bank, and for most high-income W-2 families it belongs after the tax-advantaged accounts they already have access to at work.

The idea was popularized by R. Nelson Nash in the book Becoming Your Own Banker, which called it the Infinite Banking Concept. “Bank on yourself” and “be your own bank” are marketing names for the same basic design. If you earn $750,000 or more in California or Washington, someone will likely pitch it to you, often as a “tax-free” alternative to your brokerage account. This page explains what you are actually buying and how to decide.

How an infinite banking policy is built

Every version has the same three parts.

1. A participating whole life policy. Whole life has a level premium, a death benefit, and a cash value that grows by contract. A “participating” policy may also pay dividends, which the insurer declares each year and does not have to pay.
2. Overfunding with a paid-up additions rider. The design keeps the base premium low and pushes extra money into paid-up additions, small chunks of extra paid-up insurance that add cash value faster. This is what makes early cash value higher than in a standard whole life policy.
3. Policy loans. You borrow from the insurer using your cash value as collateral. The insurer charges loan interest. Unpaid interest is added to the loan. Whatever is still owed at death is subtracted from the death benefit.

The “banking” part is only the loan. Your money is not withdrawn from an account; you are taking a loan against the policy while the cash value stays inside it. Whether the loan is cheap or expensive depends on the gap between the loan rate and what the policy is crediting, and on whether the insurer reduces dividends on borrowed cash value (called direct recognition) or not.

What the tax rules actually say

The tax case is the main reason high earners listen to the pitch, so it is worth being precise.

• Growth inside the policy is not taxed each year as long as the contract qualifies as life insurance under IRC §7702.
• Loans are generally not taxable income while the policy stays in force and is not a modified endowment contract (IRC §72(e)).
• Overfund too fast and it becomes a modified endowment contract (MEC). Under IRC §7702A, a policy fails the “7-pay test” if, at any point in the first seven contract years, the premiums paid so far exceed what seven level annual premiums would have paid for a paid-up policy by that point. For a MEC, loans are treated as taxable distributions of gain first (IRC §72(e)(10)), and before age 59½ an additional 10% tax generally applies (IRC §72(v)). The whole infinite banking design depends on staying just under this line.
• Surrender or lapse with a loan can create a tax bill with no cash. IRS Publication 525 (2025) says that if you surrender a policy for cash, “you must include in income any proceeds that are more than the cost of the life insurance policy” (Pub 525). If a large loan has grown and the policy lapses, the loan is paid off from cash value. That payoff counts as an amount received under IRC §72(e), so the gain above your cost can be taxable even though you receive little or nothing.
• Loan interest for personal use is not deductible. It is personal interest under IRC §163(h).
• The death benefit is generally income-tax-free to the beneficiary (Pub 525), but it is counted in your estate if you own the policy (IRC §2042).

California and Washington differences

In California, any taxable gain from a surrender or lapse is taxed as ordinary income, and California has no lower rate for capital gains in any case (FTB). The top California rate is 13.3% for 2025, including the 1% Behavioral Health Services Tax on taxable income over $1,000,000. So the tax deferral inside a policy is worth more to a California family than to most, which is exactly why the pitch lands there.

Washington has no wage income tax for 2026, but a 9.9% tax on AGI over $1,000,000 takes effect January 1, 2028 (WA DOR). The bigger Washington issue is estate tax. The Washington exclusion is $3,076,000 for deaths from January 1 to June 30, 2026 and $3,000,000 for deaths from July 1 to December 31, 2026 (WA DOR), far below the federal $15,000,000 per person for 2026. A large death benefit on a policy you own can push a Washington estate over that line. Owning the policy in an irrevocable life insurance trust is the usual fix, and it changes who can borrow against it.

Worked example: a $950,000 household in San Jose

Assumptions (illustrative, not a quote): both parents are 40, with W-2 income of $950,000 combined from a tech employer and a hospital, two children ages 4 and 7, and no state tax benefit available for 529 contributions (California allows none). An agent proposes a whole life policy with a $60,000 annual premium for 10 years, heavily weighted to paid-up additions.

Step 1: what the same $60,000 could do first. For 2026, each parent can defer $24,500 into a 401(k). The total annual additions limit (employee, employer and after-tax money combined) is $72,000 for 2026. If the plan allows after-tax contributions with in-plan Roth conversion, and its nondiscrimination testing does not cap them, that space can be used. With an assumed $10,000 employer contribution each, that leaves $72,000 minus $24,500 minus $10,000 = $37,500 of mega backdoor Roth room per parent, or $75,000 for the couple. That is Roth money: no insurance charges, no loan interest, and tax-free growth under current law. Many families at this income already have unused room here.

Step 2: what the policy costs in the early years. Whole life cash value typically trails premiums paid for several years because of commissions, insurance charges and the insurer’s expenses. Suppose the illustration shows a surrender value of $300,000 after five years on $300,000 of premiums (an assumption for this example; real illustrations vary by insurer and design, and dividends are not fixed). You have tied up five years of savings to reach break-even, while the same money in a Roth or brokerage account would have been invested the whole time.

Step 3: what “being your own bank” costs. Say the family later borrows $100,000 from the policy for a home renovation at an assumed 5% loan rate. That is $5,000 a year in interest, not deductible. If they never repay it, the loan grows and reduces the death benefit. Whether this beats a HELOC or a securities-based line of credit depends on those rates at the time, not on anything special about the policy.

The honest conclusion for this family: the policy can work, but it typically makes sense only after the 401(k), mega backdoor Roth, backdoor Roth IRA (the Roth IRA income phase-out for married couples filing jointly is $242,000 to $252,000 for 2026, so they are above it) and 529 goals are covered, and only if there is a real need for permanent life insurance.

When whole life can be a reasonable fit

For these families, permanent insurance tends to earn its place in a few specific situations:

• Estate liquidity in Washington, where the $3,000,000 to $3,076,000 exclusion for 2026 is reached by many homeowners with retirement accounts and equity compensation, and heirs may need cash to pay the tax without selling a house or concentrated stock.
• A lifelong dependent, such as a child with special needs who will need support after both parents are gone, usually paired with a special needs trust.
• A family that has filled every tax-advantaged bucket and wants a conservative, tax-deferred asset with a death benefit, and accepts the lower liquidity and long time horizon.

For the more common need, replacing income if a parent dies while the kids are young, term life insurance usually does the job at a fraction of the premium. See our notes on investment and risk management.

Questions to ask before you sign

1. Is the policy designed to pass the 7-pay test, and what happens to MEC status if we reduce or skip a premium?
2. Show the year-by-year surrender value using only the contractual minimum values, not the dividend projection. When does surrender value equal premiums paid?
3. What is the policy loan rate, is it fixed or variable, and does the insurer use direct or non-direct recognition?
4. How is the agent paid, and how does the commission change if we shift money from base premium to paid-up additions?
5. Who should own the policy (us or a trust), and what does that mean for estate tax and for borrowing?

A commissioned seller has an incentive to answer these in one direction. If you want a second read, a fee-only fiduciary who does not sell insurance can review the illustration. Our pages on fiduciary advisors and what advice costs explain the difference.

Common mistakes with infinite banking

• Buying it before using the workplace plan. Unused mega backdoor Roth room is usually the better “tax-free” bucket.
• Treating dividends as fixed. Illustrations assume the current dividend scale continues. It can go down.
• Letting loans run unmanaged. A growing loan against a shrinking margin can lapse the policy and trigger taxable gain.
• Stopping premiums in year three. Early surrender typically returns less than you paid in.
• Ignoring the estate. A policy you own counts toward your taxable estate, which matters most in Washington.

What to write down for your kids

A whole life policy can outlast you by decades, and your children may one day own it, inherit it or be the trustee of the trust that holds it. Write a one-page Decision Memo: why you bought it (or declined it), who owns it, the loan balance and loan rate, the premium plan, and what you would want done with it if you were not here. Keep it in your FamilyKnowledge® Library next to the policy documents. As Kevin Luu puts it: “Your kids don’t need to inherit your portfolio. They need to inherit your decision-making process.”

Frequently asked questions

Is infinite banking a scam?

No. It uses a legal, regulated insurance contract, and the tax rules it relies on are in the Internal Revenue Code. The problem is usually the sales framing. It is often sold as a bank replacement or a better investment, when it is really permanent life insurance with a loan feature, high early costs and a long break-even period.

Are infinite banking loans really tax-free?

Loans from a policy that is not a modified endowment contract are generally not taxable while the policy stays in force (IRC §72(e)). They become a tax problem if the policy is a MEC, or if it is surrendered or lapses with a loan outstanding, when gain above your cost can be taxable income (Pub 525 for surrenders; IRC §72(e) for the loan payoff at lapse).

Is infinite banking the same as “bank on yourself”?

Broadly, yes. Both describe an overfunded, dividend-paying whole life policy used as a source of loans. The names come from different promoters and designs vary by insurer, so compare the actual illustrations and contract terms rather than the label.

Next step

If you have an infinite banking illustration in hand, compare it line by line with your unused 401(k), mega backdoor Roth and 529 capacity for 2026 before you pay the first premium. Our retirement and employee benefits and estate planning teams can review both sides as part of a Tax & Wealth Assessment at Age Five Family Office™.

This is general education, and the right move depends on the family’s full picture.
