The three types of trusts used in estate planning are revocable living trusts, irrevocable trusts, and testamentary trusts. A revocable living trust is set up while you’re alive, keeps you in control, and lets your assets skip probate when you die. An irrevocable trust is a permanent transfer that removes assets from your taxable estate and shields them from your personal creditors. A testamentary trust is written into your will and only comes into being after you die, once the will clears probate. Which one fits depends on how much control you want to keep, whether estate tax or creditor exposure is a real concern, and when you want the trust to actually start working.
Revocable Living Trusts
A revocable living trust is created during your lifetime and leaves you with full control over the assets you put into it. You can change the terms, add or remove property, or dissolve the trust whenever you want. Most people name themselves as the initial trustee, so managing trust property feels no different from managing your own accounts.
Funding Is the Step People Skip
Signing the trust document is only the beginning. The trust does nothing until you re-title assets into its name, which means updating ownership on bank accounts, brokerage accounts, and real estate deeds so they list the trust rather than you personally. Financial institutions move at their own pace, and the funding process often takes several weeks.
This is where most estate plans quietly fail. If you sign a trust but never re-title your property, those assets still belong to you individually and will go through probate when you die. Every account or deed you forget to transfer is a hole in the plan.
A pour-over will acts as a backstop. It names your living trust as the beneficiary, so anything you didn’t transfer during your lifetime gets directed into the trust after you die. The catch is that those assets still go through probate first, so a pour-over will cuts the risk of intestacy without delivering the probate avoidance the trust itself provides.
Protection If You Become Incapacitated
One of the most underappreciated benefits of a revocable trust is what happens if you can’t manage your own affairs. The trust names a successor trustee who steps in automatically, without any court proceeding. That person can pay your bills, manage investments, and file tax returns. Without a funded trust, your family would likely need to petition a court for a conservatorship or guardianship, which is slower, more expensive, and public.
Probate Avoidance and Privacy
When you die, assets held in a properly funded revocable trust pass directly to your beneficiaries under the terms you set, with no court involvement. Probate costs vary by location, but between attorney fees, executor commissions, and court costs, they commonly run 3% to 8% or more of the estate’s value. Probate is also public, so anyone can look up what you owned and who inherited it. A revocable trust keeps those details private.
Tax Treatment During Your Lifetime
The IRS treats a revocable living trust as a grantor trust, meaning it isn’t a separate taxpayer while you’re alive. All income flows onto your personal return using your Social Security number.1Office of the Law Revision Counsel. 26 USC 671 – Trust Income, Deductions, and Credits Attributable to Grantors and Others as Substantial Owners No separate tax ID, no additional return. The trust is essentially invisible to the IRS until after you die.2Internal Revenue Service. IRM 21.7.13 – Assigning Employer Identification Numbers
At your death the trust typically becomes irrevocable, and the successor trustee will need to apply for an Employer Identification Number if the trust continues to hold assets rather than distribute them immediately. Assets inside a revocable trust at your death also qualify for a step-up in tax basis to fair market value, just like assets you owned individually.3Office of the Law Revision Counsel. 26 USC 1014 – Basis of Property Acquired From a Decedent That step-up can save beneficiaries a significant amount in capital gains tax when they eventually sell.
Irrevocable Trusts
An irrevocable trust is a permanent arrangement. Once you sign the document and transfer assets into it, you generally cannot take them back, change the terms, or dissolve the trust on your own. Modifications usually require the agreement of all beneficiaries, a court petition, or in some states, decanting, where the trustee moves assets into a new trust with updated terms.
The permanence is the point. By giving up ownership and control, you accomplish things a revocable trust cannot: removing assets from your taxable estate, shielding them from personal creditors, and positioning them for long-term protection across generations.
Estate Tax Savings
The federal estate tax applies to everything you own at death, with a top rate of 40%.4Office of the Law Revision Counsel. 26 USC 2001 – Imposition and Rate of Tax For 2026, the basic exclusion is $15 million per individual and $30 million for married couples under the One Big Beautiful Bill Act, which permanently raised the exemption and removed the scheduled sunset.5Internal Revenue Service. What’s New – Estate and Gift Tax If your estate exceeds those thresholds, the excess is taxed at rates reaching 40%.
An irrevocable trust removes transferred assets from your gross estate because you no longer own them.6Internal Revenue Service. Estate Tax The transfer counts as a completed gift. If it exceeds the $19,000 annual exclusion per recipient, you’ll need to file Form 709, and the excess typically applies against your lifetime exemption rather than triggering an immediate tax bill.7Internal Revenue Service. Instructions for Form 709
The Compressed Income Tax Brackets
Here’s a tradeoff almost nobody expects. Because the trust is a separate taxpayer, it needs its own Employer Identification Number and files its own annual return.2Internal Revenue Service. IRM 21.7.13 – Assigning Employer Identification Numbers Trust tax brackets are brutally compressed. For 2026, a trust hits the top 37% federal income tax rate on income above just $16,000. An individual filer doesn’t reach that rate until income exceeds $640,600. Undistributed trust income is taxed at the highest rates far faster than it would be in a person’s hands.
The escape valve is distributions. When the trustee distributes income to beneficiaries, the trust takes a deduction and the beneficiaries report that income on their own returns at their individual rates, which are almost always lower. Good trustees time distributions with this in mind.
Asset Protection and Its Limits
Assets inside an irrevocable trust are generally beyond the reach of the grantor’s personal creditors because you no longer own them. The protection has limits. Transfers made while you have existing debts, or with the intent to avoid paying creditors, can be challenged as fraudulent conveyances. States impose their own lookback windows for such challenges, and federal law adds its own rules in bankruptcy. Timing matters. Transfers made years before any financial trouble arises are far more defensible than last-minute moves.
Common Varieties of Irrevocable Trust
Irrevocable trust is more of a category than a single tool. A few specialized versions come up often:
- An irrevocable life insurance trust, or ILIT, holds a life insurance policy so the death benefit stays out of your taxable estate. The trustee owns the policy, pays premiums using gifts you contribute, and collects the proceeds when you die. If you transfer an existing policy into the ILIT and die within three years, the proceeds get pulled back into your estate. Buying a new policy inside the trust from the start avoids that risk.
- A special needs trust lets family members provide for a person with a disability without disqualifying them from means-tested government benefits like Supplemental Security Income or Medicaid. A first-party special needs trust must be established for someone under 65 who meets the Social Security disability standard, and any funds remaining when the beneficiary dies must reimburse the state for Medicaid costs. Trust funds spent on things other than food and shelter don’t reduce the beneficiary’s SSI check.8Office of the Law Revision Counsel. 42 USC 1396p – Liens, Adjustments and Recoveries, and Transfers of Assets9Social Security Administration. SSI Spotlight on Trusts
- A spousal lifetime access trust, or SLAT, lets a married couple move assets out of one spouse’s estate while preserving indirect access. One spouse creates the trust naming the other as beneficiary. The risk is that if the beneficiary spouse dies or the couple divorces, the grantor spouse loses access to the trust assets.
Testamentary Trusts
A testamentary trust doesn’t exist while you’re alive. You create it by writing instructions into your will, and it only comes into being after you die and the will clears probate. It has no power to avoid probate and offers no incapacity protection, because it simply isn’t operational until a court validates your will and authorizes the trustee to act.
Probate and Public Disclosure
Because a testamentary trust is born from a will, every asset that funds it must first pass through probate. The court authenticates the will, oversees the settlement of the estate, and transfers the designated assets into the trust. The will itself, the inventory of estate assets, and the trust terms all become part of the court record, so anyone can look them up. Families who value privacy find this a real drawback compared to a revocable living trust, which operates entirely outside the court system.
Ongoing Court Supervision
Court involvement doesn’t end once the trust is funded. Testamentary trustees typically face continuing oversight that trustees of living trusts do not. In many jurisdictions the trustee must file detailed accountings on a regular schedule, often annually, showing income received, disbursements made, and assets on hand. Courts can also require the trustee to post a bond. Failing to file on time can lead to penalties paid from the trustee’s own pocket, or removal.
That supervision cuts both ways. It creates administrative burden and ongoing cost, but it also provides a built-in check on the trustee’s honesty and competence. For families worried about whether a trustee will actually follow the terms, court oversight can be reassuring.
When a Testamentary Trust Fits
The most common use is providing for minor children or beneficiaries who aren’t ready to handle a large inheritance outright. You can condition distributions on reaching a certain age or completing a degree. A parent with young children might direct that trust income cover education and living expenses until the child turns 25 or 30, with the remaining principal distributed in stages after that.
Testamentary trusts also help when cost is a concern during your lifetime. There’s nothing to set up or fund while you’re alive, and the creation costs come out of the estate after death. For someone whose estate is modest enough that probate isn’t a major burden, a testamentary trust embedded in a will can accomplish many of the same protective goals as a living trust without the upfront expense of re-titling assets.
Side-by-Side Differences That Decide the Choice
Tax Basis at Death
One detail that catches families off guard is how each type affects the tax basis of inherited property. When someone dies owning appreciated assets, the basis of those assets generally resets to fair market value at the date of death, eliminating built-up capital gains so beneficiaries owe little or no capital gains tax if they sell shortly after.3Office of the Law Revision Counsel. 26 USC 1014 – Basis of Property Acquired From a Decedent
Assets in a revocable living trust qualify for the step-up because the grantor retained full control and the property is included in the gross estate for tax purposes. Assets in a testamentary trust also qualify, since they pass through the estate directly. The picture is more complicated with irrevocable trusts. If the trust was designed to exclude assets from the grantor’s gross estate, those assets may not receive a step-up at the grantor’s death. The estate tax savings can be substantial, but beneficiaries may eventually face higher capital gains taxes when they sell.
Medicaid and Long-Term Care Planning
Irrevocable trusts play a significant role in long-term care planning, with strict timing. Medicaid uses a 60-month lookback: assets transferred into an irrevocable trust within five years of applying for Medicaid long-term care benefits trigger a penalty period during which you’re ineligible.8Office of the Law Revision Counsel. 42 USC 1396p – Liens, Adjustments and Recoveries, and Transfers of Assets Transfers made more than 60 months before the application aren’t penalized.
The individual asset limit for Medicaid eligibility through SSI is just $2,000, or $3,000 for a couple.10Centers for Medicare and Medicaid Services. 2026 SSI, Spousal Impoverishment, and Medicare Savings Program Resource Standards Assets inside a properly structured irrevocable trust are generally not counted, because you no longer own them. A revocable trust provides zero Medicaid protection, since you retain the ability to take the assets back at any time. Families who wait until a health crisis to explore trust planning often discover they’ve missed the five-year window, and at that point the options narrow considerably.
Setup and Ongoing Costs
Legal fees for drafting a basic revocable living trust typically run $1,000 to $3,500, depending on complexity and location. Complex irrevocable trusts, especially those with tax planning strategies or multiple beneficiaries, generally fall at the higher end of that range or above. Re-titling assets into a trust adds recording fees for deeds and paperwork at financial institutions.
Ongoing costs differ sharply by type. A revocable trust you manage yourself costs essentially nothing to maintain year to year. An irrevocable trust that files its own return adds annual tax preparation fees, and a corporate or bank trustee typically charges 1% to 2% of trust value annually, with larger trusts receiving lower percentage rates. Testamentary trusts carry the cost of probate first, followed by regular court filings and trustee accountings for as long as the trust remains active.
How to Pick Among the Three
For most people, a revocable living trust is the starting point. It avoids probate, protects you during incapacity, and costs relatively little to maintain. If your estate is under the $15 million federal exemption and asset protection isn’t a primary concern, a revocable trust paired with a pour-over will handles the bulk of what estate planning needs to do.5Internal Revenue Service. What’s New – Estate and Gift Tax
Irrevocable trusts earn their complexity when estate taxes are a real risk, when you need to protect assets from creditors or lawsuits well in advance, or when Medicaid planning requires moving assets outside your name years before you’ll need long-term care. The loss of control is real and permanent, so these trusts shouldn’t be created casually.
Testamentary trusts fit people who want structured, conditional distributions to children or other beneficiaries but don’t need probate avoidance or incapacity protection. They cost nothing to maintain during your lifetime and activate only when needed. For estates where probate is straightforward, this is often the simplest path to a controlled inheritance.
