Overview
A trust is a formal legal arrangement that separates legal ownership (held by the trustee) from beneficial ownership (held by the beneficiaries). People use trusts to manage assets during life, provide for loved ones after death, reduce probate delay and public court involvement, and—when properly structured—help achieve estate, tax, and asset-protection goals.
Trusts are highly flexible. They can hold nearly any asset: bank accounts, investments, real estate, life insurance policies, business interests, and personal property. The trust instrument (the written trust agreement) specifies who the beneficiaries are, how and when assets are distributed, who serves as trustee, and what powers the trustee has.
How a trust works (step-by-step)
- Creation: A grantor drafts a trust agreement (often with an attorney) that names beneficiaries and a trustee, identifies trust property, and sets distribution rules.
- Funding: The grantor transfers title to assets into the trust (called funding). Until funding occurs, the trust holds no property and has limited practical effect.
- Administration: The trustee follows the trust terms, invests assets prudently, pays expenses, taxes, and makes distributions to beneficiaries.
- Termination: A trust may end according to its terms—at a specific date, when purposes are fulfilled, or upon the death of the grantor—after which remaining assets are distributed to beneficiaries.
Common types of trusts
- Revocable (living) trust: Grantor can amend or revoke the trust during life. These avoid probate for assets titled in the trust and provide continuity of management if the grantor becomes incapacitated. Most revocable trusts are grantor trusts for income-tax purposes while the grantor lives.
- Irrevocable trust: Generally cannot be changed without beneficiary consent. Irrevocable trusts are used for estate tax planning, Medicaid planning, creditor protection, and removing assets from the grantor’s taxable estate.
- Testamentary trust: Created by a will and takes effect only after the testator’s death.
- Special-purpose trusts: Spendthrift trusts, dynasty trusts, charitable trusts, qualified personal residence trusts (QPRTs), and others designed for specific goals.
(For a deeper look at trust types and when each is appropriate, see our glossary entries for types of trusts and trust administration.)
Who pays tax on a trust’s income?
Tax treatment depends on trust classification under the Internal Revenue Code:
- Grantor trust: If the grantor retains certain powers or ownership attributes (IRC sections 671–679), the trust is a grantor trust. The income is reported on the grantor’s personal tax return (Form 1040), not on Form 1041. Grantor trusts can simplify reporting while the grantor is alive, but tax consequences arise on certain transfers and at death.
- Non-grantor (taxable) trust: A trust that is not a grantor trust is a separate taxpayer. It generally files Form 1041 (U.S. Income Tax Return for Estates and Trusts) when it has taxable income or gross income of $600 or more, or if a beneficiary is a nonresident alien (see IRS Form 1041 instructions) [1].
Trusts that make distributions to beneficiaries can deduct the distributed income; beneficiaries then report that income on their individual returns and receive a Schedule K-1 showing their share of income, deductions, and credits.
Trustee duties and practical responsibilities
A trustee has fiduciary duties to beneficiaries: loyalty, prudence, impartiality, and acting in the beneficiaries’ best interests. Practical trustee tasks include:
- Safeguarding and investing trust assets prudently.
- Keeping accurate records and providing accountings to beneficiaries when required.
- Filing trust tax returns (Form 1041) and issuing Schedule K-1s to beneficiaries when applicable.
- Paying trust expenses, income taxes (if the trust is taxable), and distributions as directed by the trust.
Choosing the right trustee—an individual, bank, or professional trustee—is a central practical decision. Trustees should understand investments, taxes, recordkeeping, and conflict resolution. For more on the role and selection of a trustee, see our trustee glossary entry.
Funding a trust and why it matters
A trust’s effectiveness depends on proper funding. For example, creating a revocable living trust but failing to retitle bank accounts or real estate into the trust can leave those assets subject to probate despite having a trust document.
When a grantor dies, assets properly titled in a revocable trust typically avoid probate and pass directly to named beneficiaries. For tax basis purposes, assets included in the decedent’s taxable estate generally receive a step-up (or step-down) in basis to the date-of-death fair market value, which can reduce capital gains tax for beneficiaries when they sell the assets. Whether an asset receives a step-up depends on estate inclusion rules and how the trust is structured.
Practical tax and filing notes (current guidance)
- Form 1041: A non‑grantor trust or estate files Form 1041 to report income, deductions, and distributions. The IRS provides the form and instructions on its website; see About Form 1041 for details and filing thresholds [1].
- EIN: Most trusts that file Form 1041 need an Employer Identification Number (EIN). Revocable trusts often use the grantor’s Social Security number while the grantor is alive; when the grantor dies or the trust becomes irrevocable, an EIN is usually required.
- Beneficiary reporting: Trusts that distribute income report those amounts on Schedule K-1 (Form 1041). Beneficiaries use Schedule K-1 to report taxable portions of trust income on their individual returns.
Because trust taxation and filing rules can be complex and depend on the specific trust language and transactions, consult a tax professional for filings and for decisions that affect estate and income tax exposure.
Common planning uses and trade-offs
- Probate avoidance: Revocable trusts allow assets to avoid probate, keep estate information private, and provide seamless management if the grantor becomes incapacitated.
- Estate and gift tax planning: Irrevocable trusts can remove assets from the grantor’s estate to reduce estate tax, but they also transfer control away from the grantor and may have gift-tax consequences when funded.
- Creditor protection: Certain irrevocable trusts offer creditor protection for beneficiaries—but protection depends on timing, state law, and trust type.
- Medicaid and public-benefit planning: Specialized irrevocable trusts are sometimes used to protect assets for Medicaid eligibility. These strategies are complex and governed by strict look‑back rules—work with an attorney experienced in Medicaid planning.
Each planning goal has trade-offs. For instance, revocable trusts do not offer creditor protection or estate‑tax reduction while the grantor lives. Irrevocable trusts may have strong tax or protection benefits but reduce the grantor’s control over assets.
Red flags and common mistakes
- Not funding the trust: Drafting a trust but failing to transfer assets to it defeats many of the benefits.
- Poorly written trust language: Ambiguities can create disputes, increase administration costs, and produce unintended tax results.
- Using the wrong trustee: A trustee without the necessary skills or impartiality can mishandle assets and expose the estate to liability.
- Ignoring tax compliance: Failing to file Form 1041 or issue Schedule K-1s when required can create penalties and complicate beneficiary tax returns.
Practical checklist for setting up a trust
- Identify your goals: probate avoidance, tax planning, incapacity planning, asset protection, or charitable giving.
- Select the right trust type and work with an estate planning attorney to draft clear trust terms.
- Name successor trustees and provide for trustee replacement and dispute resolution.
- Fund the trust by retitling assets and updating beneficiary designations where needed.
- Obtain an EIN when required and set up tax reporting procedures.
- Keep records, review the trust periodically, and update it when your situation changes.

Final notes and disclaimer
A trust can be a powerful tool but is not a one-size-fits-all solution. In my practice as a CFP® professional, I regularly advise clients to align trust structure with clear goals—probate avoidance, tax planning, incapacity protection, or benefit design—because the best outcome depends on the facts and on state law.
