The Incomplete Non-Grantor Trust — commonly known as an ING trust — is one of the most powerful and least publicly discussed state income tax planning strategies available to high-net-worth individuals today. For residents of high-tax states such as California, New York, New Jersey, Oregon, or Minnesota who hold significant appreciated assets, concentrated stock positions, or actively generating investment portfolios, an ING trust offers something genuinely rare in modern tax planning: a legally sound mechanism to shift the income tax situs of investment income and capital gains away from the grantor's high-tax state and into a trust domiciled in a state with no income tax — most commonly Nevada, Delaware, or Wyoming — without completing a taxable gift and without relinquishing meaningful control over the transferred assets.
At LegacyBridge Wealth, we work with high-net-worth individuals and families to evaluate sophisticated tax-planning structures not as isolated products, but as coordinated components of a comprehensive wealth, tax, and legacy strategy. The ING trust is not a gimmick or an aggressive shelter. It is a carefully engineered trust structure that navigates the intersection of federal grantor trust rules, state-level income tax apportionment, and gift tax law to create a vehicle that is simultaneously incomplete for gift tax purposes, non-grantor for income tax purposes, and resident of a no-income-tax state for state tax purposes. Understanding exactly how an ING trust works, who benefits most from it, what the genuine risks and limitations are, and how it compares to alternative strategies is essential before any asset transfer is made.
An Incomplete Non-Grantor Trust is an irrevocable trust — typically established in Nevada, Delaware, Alaska, or Wyoming — that is deliberately structured to satisfy two critical and seemingly contradictory tax characterizations at the same time.
First, the trust is incomplete for federal gift tax purposes. The grantor retains a limited power to change the beneficial interests of the trust — typically through a power to substitute beneficiaries from a defined class, or through a testamentary general power of appointment held by the grantor — such that no completed taxable gift occurs at the time of funding. The grantor does not use any gift tax exemption when transferring assets into the trust, and no gift tax return is required for the transfer itself. This is the "incomplete" element.
Second, despite the grantor's retained power, the trust is structured so that it is not treated as a grantor trust for federal income tax purposes under Sections 671–679 of the Internal Revenue Code. Under grantor trust rules, a trust is treated as owned by the grantor for income tax purposes if the grantor retains certain enumerated powers. An ING trust is carefully drafted to avoid each of those triggers, meaning the trust — not the grantor — is the taxable entity for income tax purposes. This is the "non-grantor" element.
Third, because the trust is a non-grantor trust and is domiciled in a no-income-tax state, the income and capital gains generated inside the trust are taxed at the trust level in the trust's state of domicile — not in the grantor's high-tax home state. If the trust is administered in Nevada, for example, and Nevada imposes no income tax on trust income, the result is that the trust's investment income and capital gains may bear zero state income tax — potentially for as long as assets remain inside the trust.
The ING trust's value proposition is most compelling for individuals who reside in states with high marginal individual income tax rates. California, for instance, imposes a top marginal income tax rate in excess of 13% on ordinary income and long-term capital gains. New York's combined state and city income tax rates can approach or exceed 14% for New York City residents. For a high-net-worth investor with a $20 million portfolio generating $1 million or more in annual taxable income, the difference between paying the grantor's home state rate and paying no state income tax at all represents tens or hundreds of thousands of dollars per year — and over a multi-decade compounding horizon, the cumulative economic difference can be extraordinary.
The most pronounced benefit of an ING trust is typically not the ongoing elimination of state income tax on dividends and interest — meaningful as that is — but rather the elimination of state capital gains tax on large, discrete realization events. Consider a business owner in California who is preparing to sell a closely held company with a low cost basis. A direct sale would trigger California's full capital gains rate on the entire gain. If the business interest is transferred to an ING trust in Nevada prior to the sale, and the ING trust structure is properly maintained, the capital gain on the sale may be taxable only at the federal level — with no California state income tax on the gain.
The same logic applies to concentrated stock positions, real estate sales, and other large discrete capital gain events that can be anticipated in advance with sufficient planning lead time. The ING trust is a proactive tool — it must be funded and properly established before the taxable event occurs, not as a retroactive maneuver after the gain has already been realized or the sale has already been negotiated.
Not all states are equal as trust domiciles for ING trust purposes. The most commonly used ING trust jurisdictions are Nevada, Delaware, Alaska, and Wyoming. These states are favorable because they impose no state income tax on trust income, they have modern directed trust statutes that allow separation of investment management from trust administration, they have favorable self-settled trust laws in some cases, and their courts have a developed body of trust law providing planning certainty. Nevada in particular has become the preferred jurisdiction for many practitioners because of its combination of no income tax, strong asset protection statutes, and efficient trust administration infrastructure.
A common question from high-net-worth clients is whether an ING trust is necessary when a simpler alternative — simply changing domicile to a no-income-tax state like Florida, Nevada, or Texas — accomplishes the same goal. The answer depends entirely on the client's circumstances and willingness to make a genuine change of domicile.
A true change of domicile, properly executed, does eliminate the home state's claim on future income and capital gains. For clients who are genuinely willing and able to move their primary residence, sever ties with the high-tax state, and establish a bona fide new domicile, changing residence is often the simplest and most comprehensive state income tax planning strategy available. However, domicile changes are not simple in practice for many clients. A client with deep business roots in California, a family home they are not willing to sell, ongoing business operations in New York, or children in school in a high-tax state may find that a true domicile change is either not feasible or not genuinely completed in the eyes of the departing state's tax authorities.
The ING trust is a planning alternative — not a replacement for domicile — for clients who cannot or will not change their state of residence but who want to capture state-level tax savings on specific assets or income streams that can be isolated inside the trust structure.
An ING trust is not a simple planning exercise, and the difference between a properly constructed ING trust and a defective one can be the difference between the intended tax result and a complete failure of the strategy. Several structural requirements are critical.
Most ING trust designs include a distribution committee — a group of adverse parties, typically including at least one beneficiary of the trust who is not the grantor — whose consent is required before any distribution can be made from the trust. The distribution committee's consent requirement is a critical element of the non-grantor characterization, because it ensures that the grantor does not hold a power over beneficial enjoyment that would trigger grantor trust status under Section 674 of the Internal Revenue Code. Without a properly constituted distribution committee with genuinely adverse interests, the non-grantor characterization may fail.
Establishing a Nevada ING trust does not automatically guarantee that the grantor's home state will respect the non-grantor, out-of-state treatment. Several high-tax states — most notably California — have aggressively litigated the ING trust strategy and have taken the position that trust income attributable to California-source income, California-resident trustees, or California-resident beneficiaries may be taxable in California regardless of the trust's nominal domicile. The California Franchise Tax Board has issued guidance asserting that California will tax ING trust income to the extent of California contacts, and the applicable rules are fact-intensive and evolving.
Working with experienced counsel who understands both the federal income tax treatment of the trust and the specific rules of the grantor's home state is not optional — it is a prerequisite to any meaningful planning. An ING trust that fails to withstand scrutiny from the grantor's home state is worse than no plan at all, because it creates both the administrative burden of trust maintenance and the tax liability the grantor sought to avoid.
Because the transfer to an ING trust is treated as an incomplete gift for federal gift tax purposes, the assets transferred to the trust — and their subsequent appreciation — remain in the grantor's gross estate for federal estate tax purposes. This is a critical distinction: the ING trust is an income tax planning vehicle, not an estate tax reduction vehicle. Clients who are also seeking to remove assets from their taxable estate must use separate structures — such as a completed gift to an Intentionally Defective Grantor Trust, a Spousal Lifetime Access Trust, or other irrevocable gift vehicles — for that objective. The ING trust and estate tax freeze structures are not mutually exclusive, but they serve different goals and must be sequenced and coordinated thoughtfully.
The ING trust strategy is most appropriate for a relatively well-defined profile of high-net-worth individuals. The ideal candidate is a resident of a high-income-tax state who holds appreciated assets — business interests, concentrated equity, investment real estate, or a large liquid portfolio — and who anticipates a specific, large capital gain event in the foreseeable future, or who generates significant ongoing investment income that would compound materially more quickly if state income tax were eliminated.
The strategy requires meaningful planning lead time. A client who is one week from signing a letter of intent to sell a business is almost certainly too late to implement an ING trust for that transaction. A client who is two to five years from a planned business exit, or who is willing to hold a concentrated position inside the trust for an extended period before sale, is in a much stronger planning position. The ING trust rewards anticipation and patience.
At LegacyBridge Wealth, we evaluate the ING trust candidacy not in isolation, but in the context of a client's full tax profile, estate plan, liquidity needs, and long-term wealth objectives. The structure is powerful, but it is not appropriate for every situation, and it must be integrated with the broader plan rather than pursued as a standalone tactic.
For clients who are appropriate candidates, the general implementation sequence for an ING trust involves several coordinated steps. First, the client engages experienced trust and tax counsel — typically a combination of an estate planning attorney specializing in trust design and a tax advisor familiar with the multi-state income tax issues — to draft the trust instrument and confirm the structural requirements for both non-grantor and incomplete-gift characterization. Second, an independent trustee domiciled in the chosen no-income-tax state is engaged, along with a properly constituted distribution committee. Third, the trust is funded with the target assets — which may require careful analysis of the assets' existing basis, any existing agreements or restrictions, and the optimal sequencing of asset contributions. Fourth, the trust is administered in compliance with the ongoing requirements for the domicile state, including record-keeping, trust accountings, and investment management protocols. Fifth, any required federal or state filings — including the trust's federal income tax return on Form 1041 — are maintained on a timely basis.
The ongoing administrative requirements of an ING trust are not trivial. This is not a set-and-forget structure. The trust must be administered with genuine independence, proper record-keeping, and ongoing attention to any changes in applicable state tax law — particularly in aggressive states like California and New York that continue to challenge the strategy through administrative guidance and litigation.
An intellectually honest assessment of the ING trust must acknowledge the strategy's limitations. The state income tax benefits — while potentially substantial — are not guaranteed in all states and for all income types. The strategy requires a meaningful upfront investment in legal fees, trust establishment costs, and ongoing administration expenses, which must be weighed against the expected tax savings. The assets inside the trust remain in the grantor's taxable estate, so the strategy provides no estate tax benefit. And the legal landscape continues to evolve, with high-tax states actively seeking to assert taxing jurisdiction over trust income that their residents would otherwise shift offshore.
None of these limitations makes the ING trust inappropriate for the right candidate — but they do underscore that this is a strategy that demands experienced, coordinated professional guidance, not a do-it-yourself planning approach or a transaction driven primarily by a promoter's fee incentive. The clients for whom the ING trust delivers genuine, lasting value are those who approach it as one carefully considered component of a comprehensive wealth strategy, not as a standalone shortcut to tax reduction.
In an ING trust, 'incomplete' refers to the fact that the grantor retains a specific power — typically a testamentary power of appointment or a power to change beneficial interests among a defined class — that causes the transfer to the trust to be treated as an incomplete gift under federal gift tax rules. Because the gift is incomplete, no taxable gift occurs when assets are funded into the trust, and the grantor does not use any lifetime gift tax exemption on the transfer. This is a critical design feature: it allows a high-net-worth individual to move assets into the trust without triggering gift tax or consuming exemption, while still achieving the non-grantor trust treatment that shifts income tax liability to the trust level and away from the grantor personally.
In a properly structured ING trust, the trust itself — not the grantor — is the taxpayer for federal income tax purposes. The trust files its own federal income tax return (Form 1041) and pays tax on its income at trust income tax rates. Because the trust is domiciled in a state with no income tax, such as Nevada or Wyoming, the trust's income and capital gains are generally not subject to state income tax in the trust's domicile state. This is the mechanism by which the ING trust eliminates state income tax: the income is taxed at the trust level, not the grantor's level, and the trust resides in a zero-income-tax state. However, the grantor's home state may still assert taxing jurisdiction over some or all trust income depending on state-specific rules, which is why careful legal analysis of the grantor's home state rules is essential.
No — an ING trust is an income tax planning vehicle, not an estate tax reduction tool. Because the transfer to the trust is treated as an incomplete gift for federal gift tax purposes, the assets in the trust remain in the grantor's gross estate for federal estate tax purposes. When the grantor dies, the trust assets will be included in the grantor's taxable estate and subject to estate tax to the extent the estate exceeds the applicable exemption. Clients who want both state income tax savings and estate tax reduction need to use separate, coordinated structures — such as completed irrevocable trusts, GRATs, or other wealth transfer vehicles — for the estate tax objective. The ING trust and estate tax reduction strategies can coexist in a comprehensive plan, but they must be sequenced thoughtfully.
The ING trust requires meaningful advance planning — generally, the trust should be established and funded well before any specific capital gain event is imminent or contractually committed. The exact required lead time depends on the facts, but clients should engage counsel at least several months before a planned business sale, and ideally one to several years in advance. The critical issue is that the transfer to the trust must be completed before the asset is effectively sold — meaning before a binding agreement is in place, before the economic risk of the transaction has shifted, and before the gain has effectively accrued to the grantor personally. Attempting to fund an ING trust after a letter of intent has been signed or a sale has been agreed in principle is almost certainly too late to achieve the intended state income tax result.
California is the most aggressive state in challenging ING trust strategies. The California Franchise Tax Board has taken the position that it can assert income tax jurisdiction over trust income to the extent the trust has California contacts — including California-resident trustees, California-resident beneficiaries, or California-source income. New York has also asserted taxing jurisdiction over trust income in various contexts under its resident trust rules and throwback tax provisions. Clients who reside in California or New York considering an ING trust must receive specific legal analysis of how their home state's rules interact with the trust structure, and must not assume that a Nevada domicile automatically eliminates all home-state tax exposure. In some cases, the expected benefit survives careful structuring; in others, the state-level exposure may reduce or eliminate the strategy's value for that particular client.
