Irrevocable Trusts in Connecticut
An irrevocable trust is one the grantor cannot unilaterally revoke or amend after creation. That loss of control is the entire point. Because the grantor has relinquished dominion over the trust property, the assets may be excluded from the grantor’s taxable estate, protected from the grantor’s creditors, or treated as unavailable for Medicaid eligibility purposes, depending on the trust’s structure.
Connecticut practitioners use several types of irrevocable trusts, each designed for a specific planning objective.
Irrevocable Life Insurance Trusts (ILITs)
An ILIT holds life insurance policies outside the insured’s taxable estate. Without the trust, life insurance proceeds are included in the insured’s gross estate under IRC 2042 if the insured held any incidents of ownership in the policy at death.
The ILIT is created by someone other than the insured (or by the insured, who then waits three years after transferring the policy to the trust, per IRC 2035). The trustee applies for and owns the policy. The insured makes annual gifts to the trust, and the trustee uses those gifts to pay premiums. Beneficiaries receive Crummey withdrawal notices, giving them the right to withdraw each contribution for a limited period, which qualifies the contributions as present-interest gifts eligible for the annual gift tax exclusion.
At the insured’s death, the proceeds pass to the trust beneficiaries free of both estate tax and income tax. For a married couple with a combined estate approaching or exceeding the federal and Connecticut exemption thresholds, an ILIT can shelter millions in insurance proceeds from taxation.
Grantor Retained Annuity Trusts (GRATs)
A GRAT allows the grantor to transfer appreciating assets to an irrevocable trust while retaining a fixed annuity payment for a term of years. At the end of the term, the remaining trust assets pass to the beneficiaries.
The taxable gift upon creation equals the value of the property transferred minus the present value of the retained annuity. By structuring the annuity to return nearly the full value of the transferred property (a “zeroed-out” GRAT), the grantor can reduce the taxable gift to near zero.
The planning bet: if the trust assets appreciate faster than the IRS assumed rate (the Section 7520 rate), the excess appreciation passes to the beneficiaries gift-tax-free. GRATs work best in low-interest-rate environments and with assets expected to appreciate significantly during the trust term.
The risk: if the grantor dies during the trust term, some or all of the trust assets are pulled back into the grantor’s estate. Short-term rolling GRATs (two-year terms, repeated) mitigate this mortality risk.
Qualified Personal Residence Trusts (QPRTs)
A QPRT removes a personal residence from the grantor’s taxable estate at a discounted gift tax cost. The grantor transfers the residence to an irrevocable trust, retains the right to live in the home for a specified term of years, and at the end of the term, the home passes to the remainder beneficiaries.
The gift tax value is discounted because the beneficiaries do not receive the property until the end of the term. The longer the retained term, the greater the discount, but the greater the risk that the grantor dies during the term (which would pull the residence back into the estate).
After the term expires, the grantor must pay fair market rent to continue living in the home. This rent payment is itself a form of additional wealth transfer.
QPRTs are less popular than they once were, partly because rising exemption amounts have reduced the number of estates subject to tax and partly because of the unfavorable income tax basis consequences. The beneficiaries receive the grantor’s carryover basis (not a stepped-up basis), which can result in significant capital gains tax on a later sale.
Medicaid Asset Protection Trusts
A Medicaid trust (sometimes called a Medicaid asset protection trust or MAPT) is an irrevocable trust designed to protect assets from being counted as available resources for Medicaid long-term care eligibility. The grantor transfers assets to the trust and retains no right to the principal. The trust is typically structured so that the grantor may receive income but cannot access the corpus.
The critical planning horizon: Connecticut applies a five-year lookback period for Medicaid eligibility. Transfers to a Medicaid trust made within five years of a Medicaid application will result in a penalty period of ineligibility. The trust must be created and funded well in advance of any anticipated need for long-term care.
Important limitations apply. The grantor cannot serve as trustee. The trust must be truly irrevocable; any retained right to revoke, amend, or access principal will cause the assets to be counted as available. The trust cannot be structured to give the grantor a right to compel distributions.
The Connecticut Qualified Dispositions in Trust Act (CGS 45a-487j et seq.) expressly excludes from its protections any disposition that would defeat a state or federal Medicaid claim or affect Medicaid eligibility determinations (CGS 45a-487k(6)(A) and (B)). Medicaid trusts rely on different legal principles than domestic asset protection trusts.
Asset Protection Benefits
Irrevocable trusts provide asset protection because the grantor no longer owns the trust property. Creditors of the grantor generally cannot reach assets in an irrevocable trust to which the grantor has no beneficial access. The more control the grantor retains, the weaker the asset protection.
For third-party beneficiaries, a properly drafted spendthrift provision prevents the beneficiary’s creditors from attaching the beneficiary’s interest in the trust before distribution. Under the CUTC (CGS 45a-499c(26)), a spendthrift provision must restrain both voluntary and involuntary transfers to be effective.
Tax Implications
The tax treatment of an irrevocable trust depends on its structure.
Grantor trusts. Many irrevocable trusts are intentionally structured as grantor trusts for income tax purposes (under IRC 671-679) even though they are irrevocable for transfer tax purposes. The grantor pays the income tax on trust income, which is economically equivalent to an additional tax-free gift to the trust beneficiaries. GRATs, QPRTs, and many intentionally defective grantor trusts (IDGTs) fall into this category.
Non-grantor trusts. Irrevocable trusts that are not grantor trusts are separate taxpayers. They file federal Form 1041 and Connecticut Form CT-1041. Trust income tax rates are compressed; in 2025, federal trust income exceeds the highest bracket at roughly $15,450. Distributing income to beneficiaries (who are taxed at their own rates, typically lower) is often preferable to accumulating it in the trust.
Estate tax. If the trust is properly structured and the grantor has not retained powers that would cause inclusion under IRC 2036-2038, the trust assets are excluded from the grantor’s gross estate for both federal and Connecticut estate tax purposes.
Modification of Irrevocable Trusts in Connecticut
The CUTC introduced flexible tools for modifying irrevocable trusts that would have been unthinkable under prior Connecticut law.
Judicial modification. Under CGS 45a-499mm, the court may modify or terminate an irrevocable trust if unanticipated circumstances make the modification necessary to further the trust’s purposes. The court may also modify trust terms to achieve the settlor’s tax objectives under CGS 45a-499nn.
Consent modification. If all beneficiaries consent, a noncharitable irrevocable trust may be modified or terminated under CGS 45a-499ll. Court approval is not required unless the modification is inconsistent with a material purpose of the trust.
Decanting. The Connecticut Uniform Trust Decanting Act (CGS 45a-545a et seq.) allows an authorized fiduciary to distribute trust property from one irrevocable trust into a new trust with modified terms. This is covered in detail in a separate article.
Nonjudicial settlement agreements. Under CGS 45a-499k, interested persons may resolve trust matters, including certain modifications, through a binding agreement without court involvement, provided the agreement does not violate a material purpose of the trust.
These modification tools have transformed irrevocable trust planning in Connecticut. A trust that was once set in stone can now be adapted to changing circumstances, tax law shifts, and family developments, subject to appropriate safeguards and procedures.
