Estate Tax
Grantor Trusts And Who Pays The Income Tax
A trust can be outside the settlor's estate for transfer tax while its income remains taxable to the settlor, and paying that tax quietly transfers further value.

Trust taxation contains an apparent contradiction that planners use deliberately. A trust can be treated as belonging to its creator for income tax and as separate for estate tax.
How the two systems diverge
Estate tax asks whether the settlor retained enough interest or control that the assets should be counted in their estate at death.
Income tax asks a different question, using its own list of retained powers that cause the trust's income to be taxed to the settlor rather than the trust.
The lists are not identical, so a trust can be drafted to fall outside the estate while still triggering income tax treatment for the settlor.
Why that combination is useful
The settlor pays income tax on trust earnings from their own funds. The trust therefore grows without the drag of tax, compounding at a faster rate.
Paying the tax is not itself treated as a further gift in many systems, which means value moves to the beneficiaries without consuming any transfer allowance.
Over a long period, that effect can transfer a substantial amount, and it does so through an obligation the settlor is required to meet anyway.
Transactions between settlor and trust
Because the settlor and the trust are the same taxpayer for income purposes, sales between them are generally not recognised as taxable events.
That allows an appreciating asset to be sold to the trust in exchange for a note without triggering gain, freezing the value in the settlor's estate at the note amount.
The technique is well established in some systems and heavily scrutinised, with the terms of the note and the trust's own assets being the usual points of challenge.
The burden on the settlor
The settlor bears a tax liability on income they do not receive, which can become uncomfortable if the trust performs well or their own circumstances change.
Some trusts include a mechanism allowing the treatment to be switched off, or permitting the trustee to reimburse the settlor for tax paid.
Reimbursement provisions carry their own risk, since a right to be repaid can look like a retained interest and endanger the estate tax position.
Why the structures stay unsettled
The divergence between the two sets of rules is a historical accident rather than a designed feature, and legislators periodically consider aligning them.
Plans built on the current divergence therefore carry legislative risk, and existing structures are not always protected when rules change.
Trust taxation varies substantially by jurisdiction and changes frequently. This is general explanation rather than tax or legal advice, and any specific structure requires a qualified professional.
