Completed Gift
Non-Grantor Trusts

What it is

A completed gift non-grantor trust does for estate tax what a SLAT does, and for income tax what a NING or DING does.

The gift is complete, so it uses lifetime exemption and removes the asset — and all of its future appreciation — from your taxable estate. The trust is a non-grantor trust, so its income is taxed at the trust level rather than flowing back onto your personal return. It can be established in any state, and your spouse and descendants can be beneficiaries. You cannot.

Why the combination matters

The income being taxed at the trust level is what opens the second door. If the trust qualifies for your home state's resident-trust exemption — the rules explained in where your trust pays income tax — its income escapes state income tax entirely. Not deferred. Escaped.

Concretely: a founder puts company shares into the trust when the business is worth $15 million. Years later it sells for $100 million. If the trust has no New York or New Jersey trustee, no in-state source income, and distributions have been managed with discipline, the state capital gains tax on $85 million of growth is never owed — on top of the estate tax already removed by the completed gift. On numbers like these, the state income tax savings alone can exceed what many clients' entire estates are worth.

The same logic applies, more modestly, to a large investment account. Dividends, interest, and gains inside the trust accumulate free of state income tax year after year. On a big enough account, over a long enough horizon, the compounding difference is substantial.

The three disciplines

The exemption is not automatic. It has to be maintained, and it takes three ongoing commitments:

1. No in-state trustee, ever. Every trustee must be domiciled outside your state. For most families this means a professional or corporate trustee in a state like Nevada, Delaware, or New Hampshire.
2. No in-state source income. Rental property in-state is disqualifying and cannot be drafted around. An operating business with some in-state income can often be restructured — in-state operations into one entity, the rest into another — but that takes lead time, ideally years before a sale.
3. Disciplined distributions. Beneficiaries who live in-state are fine; distributions to them are the problem. A capable trustee uses loans repayable at death, or defers distributions until a beneficiary relocates. In New York this discipline is non-negotiable: a throwback tax reaches accumulated income later distributed to a New York resident.

The math you must actually run

There is a real cost to non-grantor status. In a SLAT, you pay the trust's income taxes, which lets the trust compound undiminished — a quiet annual gift that uses no exemption. A non-grantor trust gives that up: the trust pays its own taxes out of its own assets.

So the comparison is concrete: is the state income tax being escaped worth more than the tax-free compounding being surrendered? The answer depends on the size of the expected gain, the holding period, and your state's rates. For a large gain on a relatively short horizon, this structure usually wins decisively. For modest income over decades, the SLAT often wins. It is arithmetic, not instinct, and we run it before recommending either.

How it fits with the others

These structures are not mutually exclusive, and among substantial estates the most common pattern is a pair: a SLAT holding capital the family may want indirect access to, and a completed gift non-grantor trust holding the asset with the big gain coming. A NING or DING typically enters the picture only after the exemption has been fully used, since it consumes none.
