An irrevocable life insurance trust (ILIT) is a tool that comes up constantly in high-net-worth estate planning, and is wildly oversold to people who don't actually need it. Here's the honest version of who it helps and how it works.
The problem ILITs solve
When you die, the death benefit from a life insurance policy you own is included in your taxable estate. For most people, this doesn't matter — the federal estate tax exemption in 2026 is roughly $14 million per person ($28 million per couple), and California has no state estate tax.
If your total estate is well below that, an ILIT solves a problem you don't have. Buy your policy normally and move on.
But for families with estates approaching or above the exemption — including business owners, real estate investors, and successful professionals with appreciating assets — adding a $2 million life insurance death benefit to the estate can push them across the threshold. At a 40% federal estate tax rate, that's $800,000 of tax on the death benefit alone.
How an ILIT fixes that
Instead of owning the policy yourself, you create an irrevocable trust that owns the policy. The trust pays the premiums (you gift money to the trust to fund this). When you die, the death benefit goes to the trust, not into your taxable estate. The trustee distributes the funds to your heirs per the trust terms.
Result: the death benefit passes outside the estate, free of estate tax. The savings can be six or seven figures for the right family.
The "irrevocable" part — and why it matters
Once the trust is established and the policy is inside it, you generally cannot change it. The trustee (someone other than you) controls the policy. You can't borrow against the cash value for personal use. You can't change beneficiaries on a whim.
This is a serious commitment. The IRS treats the trust as not part of your estate precisely because you've given up control. If you retain control, the strategy fails and the death benefit gets pulled back into the estate.
Annual administration: the Crummey letter
Each year, when you contribute money to the trust to pay premiums, the contribution would normally count as a taxable gift. To avoid that, ILITs use a 'Crummey' mechanism: beneficiaries receive a brief letter giving them the right to withdraw the contribution for 30 days. They don't actually withdraw it (that's the point), but having the right qualifies the contribution for the annual gift tax exclusion ($18,000 per beneficiary in 2024, indexed for inflation).
This sounds tedious because it is. Skip the Crummey letters and the IRS may treat the contributions as taxable gifts. ILITs are not 'set it and forget it' — they require yearly maintenance with a competent attorney or trust administrator.
When ILITs are worth it
- Combined estate (including life insurance death benefit) exceeds the federal exemption
- You're buying a large permanent policy ($1M+) for estate planning purposes
- You expect significant asset appreciation between now and death
- You have the discipline and budget for annual trust administration
When they're NOT
- Estate well under the federal exemption with no expectation of changing
- Term life insurance only (no cash value, dying after the term means the trust pays nothing)
- You'd be tempted to access policy cash value during your lifetime
- You can't commit to the annual administrative work
The three-year lookback rule
If you already own a life insurance policy and transfer it INTO an ILIT, the IRS pulls the death benefit back into your estate if you die within three years. To avoid this, the ILIT should buy a NEW policy from day one, with you never having owned it.
Existing policies can sometimes still be transferred for valid reasons, but they need to outlive the three-year window. Plan accordingly.
A simple decision framework
Three questions:
- Is my combined estate over $10 million (well below the exemption today, but appreciating)?
- Am I buying $1M or more of permanent life insurance?
- Am I willing to give up control of the policy and fund the annual administrative work?
Three yeses and an ILIT may save your heirs serious money. Otherwise, simpler ownership structures are usually right.
Estate planning is highly individual. If you're working through it with an attorney and considering an ILIT, we'll coordinate the insurance side and make sure the policy matches the trust strategy.
