Funding is the plan
The most expensive mistake in estate planning is not choosing the wrong trust. It is signing the right one and never funding it. A trust only governs the assets it holds; an asset the trust does not own is controlled by its own title and beneficiary form, whatever the trust document says. A revocable living trust drafted to avoid probate avoids nothing if the house is still deeded to you personally at death — it will pass through probate exactly as if the trust did not exist.
“Funding” simply means changing the legal owner of an asset from you to the trust — or, for some assets, naming the trust as the beneficiary. The method differs by asset type, and getting the method right is most of the work. The rest of this page walks through what to move, what to leave alone, and how each transfer is done.
What belongs in a trust
The assets that most often belong in a revocable living trust are the ones that would otherwise pass through probate and that carry their title in your name:
- Real estate — your home, rental property, and land, moved by a new deed naming the trustee as owner.
- Non-retirement investment and bank accounts — brokerage accounts, and often checking and savings, re-registered in the trust’s name.
- Closely held business interests — LLC membership units, partnership interests, and shares in a private corporation, transferred by assignment (subject to the entity’s operating agreement and any transfer restrictions).
- Valuable tangible personal property — art, collections, and heirlooms, assigned by a written schedule.
For an irrevocable trust the list is narrower and the stakes higher, because moving an asset in is generally a completed gift (see below). What goes into an irrevocable trust is usually chosen deliberately for a specific tax or protection goal — a life insurance policy into an ILIT, for instance — rather than swept in wholesale.
What usually stays out
Some assets should almost never be retitled into a living trust, because doing so triggers tax or defeats a benefit:
- Retirement accounts (IRAs, 401(k)s, 403(b)s). These are individual accounts by law. Retitling one into a trust during your life is treated as a complete distribution of the account — the whole balance becomes taxable income that year. They pass by beneficiary designation instead; whether to name a trust as the beneficiary is a separate, deliberate decision.
- Deferred annuities. An annuity owned by a non-natural person generally loses its tax deferral and is taxed every year (IRC § 72(u)) — a sharp trap with a narrow exception, covered on its own page.
- Health savings accounts. Like retirement accounts, an HSA is individually owned and passes by beneficiary designation; it is not retitled into a trust.
- Vehicles and everyday accounts, often, for practical reasons — insurance, registration, and convenience usually outweigh the small probate saving.
How each asset type moves
The mechanics differ by asset because the law of title differs by asset. This table is the map; the retitling page walks through each method step by step.
| Asset type | How it’s funded | Watch for |
|---|---|---|
| Real estate | New deed to the trustee, recorded with the county | Transfer-tax and reassessment rules; a due-on-sale clause (federal law exempts a transfer to a revocable trust where you remain a beneficiary and occupant — 12 U.S.C. § 1701j-3(d)(8)) |
| Brokerage / bank accounts | Re-register the account in the trust’s name | New account paperwork; update linked transfers |
| Closely held business interest | Written assignment of the membership/partnership interest | Operating-agreement transfer restrictions; S-corporation eligibility (the trust must be a permitted shareholder) |
| Tangible personal property | Written assignment / schedule of property | Titled items (e.g., vehicles) follow their own title rules |
| Life insurance | Change owner and/or beneficiary to the trust (an ILIT is purpose-built for this) | The three-year rule on transferring an existing policy (IRC § 2035) |
| Retirement accounts | Not retitled during life — beneficiary designation only | Retitling is a taxable distribution; name beneficiaries carefully |
| Deferred annuity | Ownership change only with eyes open — see § 72(u) | Loss of deferral for a non-natural-person owner |
Sources: the Internal Revenue Code sections linked in each row; 12 U.S.C. § 1701j-3(d)(8) (Garn–St Germain due-on-sale exemption). Entity-transfer restrictions are governed by the asset’s own operating agreement and applicable state law.
Revocable vs. irrevocable: funding is not the same act
The single most important distinction in trust funding is whether the trust is revocable or irrevocable, because it changes whether the transfer is a taxable event.
Funding a revocable living trust is not a gift and not a taxable event. Because you keep the power to revoke the trust and take the assets back, you remain the owner for income-tax purposes — the trust is a “grantor trust” under IRC § 676 — and the assets remain in your gross estate under IRC § 2038. You keep your Social Security number on the accounts, file no separate trust return, and the assets still receive a step-up in basis at death (IRC § 1014). Nothing about your taxes changes; only the title does.
Funding an irrevocable trust generally is a completed gift. Moving an asset into a trust you no longer own and cannot revoke is a transfer for gift-tax purposes, reportable on Form 709 and charged first against your annual exclusion and then against your lifetime exemption (IRC § 2501; § 2503; § 2010). That is exactly how an irrevocable trust removes value from a taxable estate — but it is a decision with real tax mechanics, and the asset generally leaves your estate and loses the date-of-death basis step-up (see below).
The tax that turns on funding
Three tax rules do most of the work in deciding what to fund where, and each has its own page in this cluster:
- The basis step-up (§ 1014). Assets included in your gross estate at death take a new basis equal to their date-of-death value, wiping out unrealized capital gain for your heirs. Revocable-trust assets keep this benefit; assets given away into an irrevocable trust generally do not. The IRS confirmed in Rev. Rul. 2023-2 that assets in an irrevocable grantor trust that are not included in the grantor’s gross estate get no step-up — a point covered on the funding-mistakes page.
- The § 72(u) annuity rule. A deferred annuity owned by a trust generally loses its tax deferral. When it does, when the “agent for a natural person” exception saves it, and how grantor-trust status changes the answer are on the annuities-in-trust page.
- Income in respect of a decedent (§ 691). When a trust is the beneficiary of a deferred annuity or a retirement account, the built-in gain is taxed as income in respect of a decedent — no step-up, and often a compressed payout — as explained on the trust-as-annuity-beneficiary page.
None of this is a reason to avoid trusts. It is the reason funding is a decision, not a formality: the same asset can belong in one kind of trust and be a costly mistake in another.

Common questions
If I signed my trust, isn't it done?
No. A trust is a set of instructions for property the trust owns. Until an asset is retitled into the trust's name — a deed re-recorded, an account re-registered, a business interest assigned — the trust owns nothing and controls nothing. The signed document and the funding are two separate acts, and the second is the one people skip. An unfunded revocable living trust does not avoid probate, because at death the assets are still titled in your own name and must pass through it.
Should I put my retirement accounts into my trust?
Generally not during life. Retitling an IRA or 401(k) into a trust is treated as a full distribution — the entire balance becomes taxable income in that year (IRC § 408(a) contemplates an IRA owned by an individual; assignment to a trust is a deemed distribution). These accounts pass by beneficiary designation, not by the trust's terms, so you control them through the beneficiary form. Whether to name a trust as the beneficiary is a separate, careful decision covered on the retirement-account pages.
Does moving an asset into a revocable trust change my taxes now?
For a revocable living trust, no. Because you keep the power to revoke, you remain the owner for income-tax purposes (the trust is a grantor trust under IRC § 676), and the assets stay in your gross estate for estate-tax purposes (IRC § 2038). You use your own Social Security number, file no separate return, and — importantly — the assets still receive a basis step-up at death (IRC § 1014). Funding a revocable trust is a titling change, not a taxable event.
Is funding an irrevocable trust a gift?
Usually yes. Moving an asset into an irrevocable trust you no longer own is a completed gift, reportable on a gift-tax return (Form 709) and charged against your annual exclusion and lifetime exemption (IRC §§ 2501, 2503, 2010). That is a feature, not a bug — it is how irrevocable trusts move value out of a taxable estate — but it is a decision with tax consequences, unlike funding a revocable trust.
