An Intentionally Defective Granter Trust (IDG) is an irrevocable trust created for estate planning purposes with the intention of shifting income and assets from the granter to beneficiaries while minimizing gift and estate taxes. The granter, who is also the trustee, maintains control over the trust assets and has the legal right to revoke the trust. The granter is also responsible for paying the trust's income taxes, which are reported as part of the granter's taxable income. The main types of Its include granter retained annuity trusts (Grants), qualified personnel residence trusts (Parts), and charitable lead trusts (Cuts). Grants are established to transfer assets to beneficiaries for a set period of time while minimizing the gift or estate tax burden. Parts allow the granter to transfer a personal residence to a trust while retaining a life estate and minimizing the gift or estate tax burden. Cuts are created to transfer assets to a charity for a set period of time while also transferring assets to beneficiaries after that period and minimizing the gift or estate tax burden.
