The logic: control means ownership
The grantor trust rules exist to stop a simple dodge — shifting income to a trust’s compressed brackets while keeping full control of the money. Sections 671 through 679 answer with a principle: retain enough control and the income tax treats the trust’s items as yours. The triggering powers include revocation, income payable to you or your spouse, the power to reacquire or swap trust assets, and borrowing without adequate security. A revocable living trust trips the very first one by design, which is why the estate-planning workhorse of avoiding probate has no income-tax life of its own.
Reporting: two clean methods
- SSN method (most revocable trusts): banks and brokers report the trust’s accounts under the grantor’s SSN; everything lands on the 1040 directly and no trust return exists.
- 1041 with a grantor statement: where the trust has its own EIN, the trustee files a Form 1041 that computes no tax and attaches a grantor information statement listing the income and deductions the grantor must report. The 1041 acts as a routing slip, not a tax return in substance.
Either way, the substantive answer is identical: the grantor pays, at the grantor’s rates — the trust’s steep compressed brackets never come into play while grantor status holds.
The day everything changes
Grantor status ends at death. From that day the trust is irrevocable, is a separate taxpayer, needs its own EIN, and files Form 1041 for its income — issuing Schedule K-1s when it distributes. Trustees administering a former revocable trust alongside a probate estate should evaluate the section 645 election: one combined Form 1041 on the estate’s fiscal year instead of two returns on two calendars.
