Revocable vs Irrevocable Trusts

Revocable trust

A revocable trust (also called a living trust or inter vivos trust) can be changed or terminated at any time by the grantor. During your life, you typically:

• Are the grantor (creator).
• Are the trustee (manager).
• Are the primary beneficiary.

You retain complete control. You can change beneficiaries, modify terms, add or remove assets, or dissolve the trust entirely.

Tax treatment: For income tax purposes, a revocable trust is a "disregarded entity" — its income appears on your personal 1040 as if you owned the assets directly. No separate tax ID or return required while you're alive.

Estate tax treatment: Assets in a revocable trust are included in your taxable estate. The trust doesn't reduce estate tax.

Creditor protection: None during your life. Because you retain control, creditors can reach trust assets.

So what's the point?

• Probate avoidance. Assets properly funded into the trust skip probate at death.
• Continuity during incapacity. A successor trustee can manage the trust if you become incapacitated.
• Privacy. Trust terms aren't public the way wills are.
• Multi-state real estate. Out-of-state real estate in the trust avoids ancillary probate in that state.

For most middle-class families who create trusts, a revocable living trust is the main tool.

Irrevocable trust

An irrevocable trust cannot be changed or terminated once created (with narrow exceptions). The grantor gives up meaningful control over the assets placed in it.

Tax treatment: Varies by trust type. Some are "grantor trusts" for income tax purposes (income reported on grantor's 1040); others are separate taxpayers with their own returns and tax rates.

Estate tax treatment: Properly structured irrevocable trusts keep assets out of the grantor's taxable estate. Appreciation post-transfer is also outside the estate.

Creditor protection: Generally strong. Because the grantor has given up control, creditors can't typically reach the assets.

Why accept giving up control? Specific goals that a revocable trust can't achieve:

• Estate tax reduction. Move assets (including future appreciation) out of the estate.
• Creditor protection for yourself and/or beneficiaries.
• Specific tax-advantaged structures (GRAT, ILIT, CRT, etc.).
• Long-term control of distributions (spendthrift provisions, age-based access).

Common irrevocable trust types

Irrevocable Life Insurance Trust (ILIT). Trust owns life insurance on your life. Death benefit passes outside your estate. Used by families whose estate is approaching the federal exemption, where life insurance proceeds would otherwise increase the taxable estate.

Grantor Retained Annuity Trust (GRAT). Short-term (2–10 year) trust where you contribute assets and receive an annuity back for the term. Remainder passes to beneficiaries (often children or a dynasty trust). Zero-tax if properly structured; gains in excess of IRS rate ("7520 rate") pass tax-free.

Spousal Lifetime Access Trust (SLAT). Gift into a trust benefiting your spouse. Uses your lifetime exemption. Your spouse accesses trust funds during life; at their death, assets pass to children. The gifted amount and appreciation are out of both estates.

Intentionally Defective Grantor Trust (IDGT). Grantor pays income tax on trust earnings (reducing their estate), while trust assets grow outside the estate. Common vehicle for sales of appreciating assets to the trust.

Charitable Remainder Trust (CRT). You contribute appreciated assets; trust pays you an income stream; remainder goes to charity. Partial deduction at funding; avoids capital gains on sale of contributed assets.

Charitable Lead Trust (CLT). Reverse of CRT — charity receives income; remainder to beneficiaries. Transfers appreciation to heirs at reduced gift tax cost.

Dynasty Trust. Long-term trust holding assets for multiple generations. Uses GST exemption to avoid transfer tax at each generation. Particularly valuable in states without rule-against-perpetuities.

Qualified Personal Residence Trust (QPRT). Gift your home to trust, retain right to live there for a term. Remainder passes to beneficiaries. Uses discounted value (for the retained interest) against gift exemption.

Special Needs Trust (SNT). Provides for a disabled beneficiary without disrupting their eligibility for government benefits (SSI, Medicaid). Not primarily a tax tool; a benefits preservation tool.

The decision framework

For most people starting estate planning:

Stage 1: Will + POAs + healthcare directives. Covers the basics.

Stage 2: Add revocable living trust if:

• Own real estate in multiple states.
• Want probate avoidance for privacy or administrative ease.
• Want continuity of management during incapacity.

Stage 3: Consider irrevocable trusts if:

• Estate exceeds or will exceed federal exemption ($15M individual / $30M couple).
• Own significant life insurance.
• Have concentrated appreciating assets.
• Have charitable intent combined with low-basis assets.
• Have a disabled family member.
• Want long-term control over beneficiary access.

Funding matters more than drafting

The most expensive and elegant trust is useless if it's not funded. Creating the trust and then not transferring assets into it (via deed changes, account retitling, beneficiary updates) defeats the purpose.

When creating any trust, the funding checklist should include:

• Real estate (new deeds).
• Investment accounts (retitling).
• Bank accounts (retitling or TOD).
• Business interests (operating agreement updates).
• Life insurance (ownership/beneficiary changes for ILIT).

Retirement accounts (401(k), IRA) are generally NOT retitled into trusts — doing so triggers immediate taxation. Instead, the beneficiary designation may name the trust.

How Horizons uses this

Horizons models the financial impact of trust structures without requiring you to specify the legal details. If you indicate that certain assets are in an ILIT or passed through a SLAT, the engine can reflect their removal from your taxable estate.
