Intentionally Defective Grantor Trust
Simple explanation
An IDGT is an irrevocable trust designed so a transfer can be complete for gift and estate tax while the grantor remains the income-tax owner; the 'defect' is intentional only in that tax-classification sense.
- Often paired with a gift and a note sale

- Valuation and note terms need coordinated advice
- Valuation, seed capital, note terms, cash flow, and retained powers require coordinated advice.
- Grantor status can end
- Grantor-trust status can end during life or at death, creating transition issues.

Questions about Intentionally Defective Grantor Trust
What determines how this trust works?
The signed governing terms, valid funding, retained powers, trustee authority, beneficiary rights, administration, tax classification, timing, and applicable state and federal law—not the trust name by itself.
Does this kind of trust automatically reduce tax or protect assets?
No automatic result follows from the label. Income, gift, estate, and GST tax classifications are separate questions, and creditor treatment depends on the settlor's and beneficiaries' rights, governing law, timing, and administration.
What should be verified before creating or funding the trust?
Verify the objective, governing instrument, fiduciaries, beneficiary standards, title and transfer restrictions, valuation, tax reporting, liquidity, governing state, expected administration, costs, and advice from appropriately qualified professionals.
