Does My Trust Need a Tax Return or an EIN?

Does My Revocable Trust Need a Tax Return?

No, not while you are living. Your revocable living trust is what the tax code calls a wholly owned grantor trust, which means the IRS looks through the trust and sees you. Its income, deductions and credits go on the personal return you already file.

The Treasury regulations say it directly. A Form 1041 is not necessarily required for a wholly owned grantor trust, because that trust’s income is reported on the grantor’s personal income tax return. Reg. §§1.6012-3(a)(9) and 1.671-4(b).

So nothing about your tax year changes because you signed a trust. The same 1040, the same schedules, the same accountant, the same April. People are frequently told otherwise by someone at a bank, and it is worth knowing the answer before that conversation rather than after.

Practice pointer. When a financial institution tells my client the trust must file its own return, I ask them to put that requirement in writing. It is nearly always an internal account-opening policy rather than a tax rule, and it usually dissolves once the words grantor trust are used.

Do I Need an EIN for My Revocable Trust?

Generally no, for the same reason. While you are alive and serving as your own trustee, the trust uses your Social Security number, because for income tax purposes it is not separate from you.

Where a trust does need its own number, the trustee applies on IRS Form SS-4. IRC §6109; Reg. §301.6109-1(a)(ii)(C). Three routes exist and they differ mostly in speed.

One route no longer exists. The IRS does not issue employer identification numbers by telephone to domestic taxpayers, so a trustee cannot get one by calling.

Practice pointer. If you apply by fax, include a fax number for the reply. The IRS returns the number the same way it arrived, and an application with nowhere to send the answer sits.

Why a Grantor Trust Files Nothing

Grantor trust status puts the legal obligation to report all of the trust’s income, deductions and credits on the grantor’s personal return. That is the mechanism, and it is why there is no second return.

The same treatment carries several consequences an owner rarely hears about, and they are favourable.

• Sales between you and the trust are not taxable events. A transaction between a wholly owned grantor trust and its deemed owner is not a realization event for income tax purposes, and loans between the two give rise to no interest income and no interest deduction.
• Your home keeps its capital gains exclusion. The benefit of IRC §121, the exclusion on the sale of a principal residence, is available where the residence is owned by a wholly owned grantor trust. Reg. §1.121-1(c)(3).
• The mortgage interest deduction still flows to you. Deductions under IRC §163(h) for a grantor trust owning the grantor’s personal residence pass through.
• S corporation stock is safe. A grantor trust deemed entirely owned by a United States citizen or resident is eligible to be an S corporation shareholder. IRC §1361(c)(2)(A)(i).

Those four are the quiet reason the revocable trust is such an easy structure to live with. Nothing about your tax picture gets more complicated while you are alive. For what the trust does and does not protect, see how a Florida revocable living trust works, and for the house specifically, homestead in a revocable trust.

My Bank Says the Trust Needs Its Own Number. Is That Right?

Clients are often confused about whether their revocable trust needs a separate tax identification number, and ask me, "The bank says it does, are they wrong?" Usually yes. I have written the same short letter to branch managers more times than I can count, explaining that a revocable trust is a grantor trust and uses the settlor’s Social Security number. It is an account-opening policy, not a tax rule, and it resolves once someone puts that in writing.

What Changes the Day You Die

Your death converts the trust from an extension of you into a separate taxpayer. Three things follow, and they follow quickly.

Two things change the answer over time. A revocable trust becomes irrevocable at the grantor's death and starts filing on its own, which is part of what the successor trustee has to do, and a trustee who is being paid for that work is taking a fee that has its own rules, covered in Florida trustee fees.

The trust becomes irrevocable, so the grantor trust treatment ends. It needs its own employer identification number, which the successor trustee obtains on Form SS-4. And somebody has to work out whether a Form 1041 is due for the year, and file it if so.

That somebody is usually a son or daughter who has never filed a fiduciary return, doing it in the same months as the funeral and the account transfers. It is the single most common place where a well-drafted plan runs into trouble, and it is not a drafting problem. It is a handoff problem.

Practice pointer. I tell every successor trustee I work with to engage the tax preparer in the year of death, not the following spring. The decisions that matter, including the election described below, are made on a timetable that starts at the death and not at the filing deadline.

When a Trust Actually Has to File

A trustee must file an income tax return for any taxable year in which one of three things is true. IRC §§6012(a)(4) to (a)(5).

• The trust has taxable income; or
• The trust’s gross income exceeds $600; or
• The trust has a beneficiary who is a nonresident alien.

They are alternatives, not a combined test, so crossing any single one creates the duty. The $600 gross income threshold is the one that catches people, because it is low enough that a trust holding an ordinary brokerage account or a rental property will clear it without anyone thinking of the trust as wealthy.

The third trigger is the one families forget. A beneficiary living abroad who is not a United States person creates a filing obligation regardless of the dollar amounts, which is worth knowing before naming beneficiaries across borders. See estate planning for non-US citizens.

Form 1041, Due Dates, and the Election That Helps

The return for a trust is filed on Form 1041. Reg. §1.6012-3(a). Where a return is required, it is due no later than the fifteenth day of the fourth month following the close of the trust’s taxable year, which for a calendar-year trust is April 15. IRC §6072(a).

A trust generally must determine its taxable income on a calendar year basis. IRC §644(a). There are exceptions. Tax-exempt and charitable trusts are not required to use a calendar year, and neither is a trust treated as a wholly owned grantor trust. Rev. Rul. 90-55.

The exception worth asking about is the election under IRC §645. A qualified revocable trust, for which an election is made to treat the trust as owned by the settlor’s estate, may effectively be permitted to select a non-calendar taxable year while the election remains in effect. In an administration that begins in the middle of a year, that flexibility can consolidate reporting and reduce the number of returns the family files.

When the trust does file, the trustee must also furnish a Schedule K-1 to each beneficiary who receives a distribution for that year or to whom a tax item is allocated. IRC §6034A(a). A beneficiary then has to report each item consistently with the trust’s return unless they notify the IRS of the inconsistency in the way the Code prescribes, and failing that procedure can bring penalties. IRC §6034A(c), (c)(5).

Practice pointer. A beneficiary who thinks a K-1 is wrong should raise it rather than simply reporting something different. The consistency rule puts the penalty on the beneficiary, not on the trustee who prepared it.

The Personal Exposure Nobody Mentions to the Trustee

Here is the part that belongs in every successor trustee conversation and is almost never in one. A failure to file a Form 1041 exposes the trustee to personal liability if the trustee had notice of the tax obligation or failed to exercise due diligence in ascertaining whether a return was due. Reg. §1.641(b)-2(a).

Read the second half of that. It is not limited to a trustee who knew and ignored it. It reaches a trustee who did not know and did not take reasonable steps to find out. Accepting the role of successor trustee for a parent is accepting that standard, usually without anyone having said so.

Practice pointer. In my experience a successor trustee’s first call should be to a tax preparer, before any distribution is made. Distributing the assets and then discovering a return was due leaves the trustee exposed with nothing left in the trust to pay it from.

One Florida Note

Everything above is federal. Florida imposes no personal income tax, so a Florida resident’s revocable trust has no state income tax return to worry about either, and that remains true after death for the state layer. The federal layer is the whole of the analysis, which is one of the quieter advantages of administering a trust here rather than in a state with its own fiduciary income tax.

Frequently Asked Questions

Common Situations

The bank that insisted. A Naples couple were told at account opening that their new revocable trust required its own tax identification number before the account could be retitled. It did not. The trust was a grantor trust using their Social Security number, and the branch was applying a policy written for irrevocable trusts. One letter resolved it.

The daughter who distributed first. A successor trustee in Palm Harbor moved quickly after her father died, closed the accounts and split the proceeds between herself and her brother within two months. A Form 1041 was due for the year of death. The money was already gone, and the regulation making a trustee personally liable does not care that she acted in good faith.

The beneficiary abroad. A Sarasota trust named a grandchild who had taken citizenship elsewhere and was no longer a United States person. That fact alone created a filing obligation independent of how much income the trust produced, and nobody had flagged it when the beneficiary designation was written.

What I See in These Files

In 14 years of law practice this question almost never reaches me from the person who made the trust. It reaches me from the adult child holding a death certificate, who has just worked out that the document naming them successor trustee also handed them a filing duty with their own name attached to the liability.

I draft these plans knowing who will be holding them, so I put the first-year instructions in writing and I say plainly that a tax preparer comes before any distribution. I have seen what happens otherwise, and there is no comfortable version of that conversation once the money has gone out. Avoid distributing trust assets before a tax preparer has looked at the year of death, and avoid assuming that a trust which filed nothing for twenty years has nothing to file now. The rule that kept it simple is the rule that ended when the settlor did, and nobody sends a notice about that.
