Grantor vs Non-Grantor Trust Calculator

Trusts have severely compressed tax brackets — 37% kicks in at just $15,200 of taxable income (2026). Grantor trust status shifts tax liability to the grantor personally, who pays at their (usually lower) marginal rates while the trust assets grow tax-free for beneficiaries.

Grantor Trust Mechanics

Under IRC §671-679, certain trust powers cause grantor to be 'owner' for income tax purposes. Trust income, deductions, and credits flow to grantor's 1040. Trust itself files a blank 1041. Common triggers: grantor retains power to substitute assets, borrow without security, distribute to grantor.

Non-Grantor Trust Compressed Brackets (2026)

Ordinary income: 10% to $3,150 / 24% to $11,450 / 35% to $15,200 / 37% above. LTCG: 0% to $3,150 / 15% to $15,200 / 20% above. Compare to individual top bracket hitting 37% at $626,350 single (2025). Trusts hit top rate 41× faster.

Distribution Deduction (DNI)

Non-grantor trusts deduct distributable net income (DNI) when distributed to beneficiaries. Beneficiary picks up that income on their 1040 (at their rates). Strategically distributing income to lower-bracket beneficiaries cuts overall tax substantially.

Estate Freeze Strategy

Intentionally Defective Grantor Trust (IDGT): grantor pays income tax on trust earnings (tax-free 'gift' that doesn't use exemption). Trust assets grow free of income tax drag. At grantor's death, assets are outside grantor's estate. Powerful tax-leveraged wealth transfer.
