One question decides everything else, and it usually gets answered by whoever prepares the first return: is the trust a grantor trust or a non-grantor trust? A grantor trust may file nothing at all, its income landing on the grantor’s own Form 1040. A non-grantor trust files its own return and reaches the top rates fast. My view is that this belongs in writing before the first year closes.
Part of our guide: Crypto Estate Planning.
The short version
- Grantor or non-grantor decides who files. Every other reporting question follows from that answer.
- A grantor trust “is not required to file a Form 1041, provided that the individual grantor reports all items of income and allowable expenses” on the grantor’s own return (IRS).
- A non-grantor trust files Form 1041 once it has $600 of income for the year, and reports what it distributes to each beneficiary on Schedule K-1.
- The IRS treats digital assets as property, so every disposition inside the trust is its own reportable event (IRS).
- Basis is identified wallet by wallet, which makes the trust’s holdings a separate accounting unit from the grantor’s personal ones.
The fork that gets answered by default
Grantor status is a conclusion drawn from the instrument’s terms. Nobody picks it at filing time. Subpart E of the code, beginning at 26 U.S.C. § 671, specifies when a grantor or another person is treated as the owner of a portion of a trust, and the income, deductions, and credits of that portion are then computed on the owner’s return. The IRS states the consequence directly:
“If a trust is a grantor trust, then the grantor is treated as the owner of the assets, the trust is disregarded as a separate tax entity, and all income is taxed to the grantor.”
IRS, Abusive trust tax evasion schemes, questions and answers
Two things follow that families miss.
The first is that a revocable living trust holding a hardware wallet typically produces no separate return at all, and that absence is correct. The record-keeping survives it: the grantor still owes an accurate 1040, and the units now sit somewhere their own exchange history does not describe.
The second is that grantor treatment depends on there being an owner to attribute the income to. When the grantor dies, that attribution ends, and a trust that filed nothing for fifteen years becomes a separate filer partway through a year, at the moment the family has the least capacity for it. An irrevocable trust can also be a grantor trust by design, a drafting choice made at funding (the irrevocable version covers it).
What the trust’s own return has to carry
The fiduciary of a non-grantor trust files Form 1041, which the IRS describes as reporting “the income, deductions, gains, losses, etc. of the estate or trust” and “the income that is either accumulated or held for future distribution or distributed currently to the beneficiaries” (IRS, About Form 1041).
That second clause is the distribution question stated as a filing requirement. The return has to say what stayed inside and what went out. What goes out reaches each beneficiary on a Schedule K-1, used “to report a beneficiary’s share of the estate’s or trust’s income” on their own return (IRS, Schedule K-1 instructions). What stays is taxed to the trust itself, on a bracket structure far narrower than an individual’s: estates and trusts reached the 20% capital gains rate above $15,900 of income in tax year 2025 (IRS, Form 1041 instructions). Selling inside a trust covers what that does to a sale decision.
The filing trigger is $600 of income for the taxable year, or a nonresident alien beneficiary. For a trust holding digital assets that is a low bar: one disposition clears it, and so does a season of staking receipts.
The transaction-level machinery underneath does not change with the wrapper. Dispositions, swaps, receipts valued at the moment of receipt, and the digital asset question on the return all work as they do for an LLC.
The trust is its own basis pool
This is the part that changed recently, and the part I see handled worst.
Basis identification for digital assets is done by wallet or account rather than across everything a taxpayer owns. Under Treas. Reg. § 1.1012-1(j), Revenue Procedure 2024-28 set out a safe harbor under which any unused basis was assigned to a particular wallet or account, measured as of 1 January 2025. The effect for a trust is structural: from the moment a trust wallet exists, it is a separate accounting unit from the grantor’s personal wallets.
Funding therefore draws a records boundary on a date, and it has to be drawn deliberately. For a grantor trust, moving units from the grantor’s wallet to the trust’s wallet generally changes nothing about who reports the income, since the same person is treated as owner throughout. It still changes the accounting unit, which is what makes the boundary easy to lose: the transfer produces no taxable event, no statement, and no prompt to write anything down, while splitting the basis records into two pools.
Broker reporting now closes part of that gap from outside. Gross proceeds go on Form 1099-DA for transactions from 1 January 2025 forward, with basis added for certain transactions from 1 January 2026 (IRS, Digital assets). The form names whoever holds the account, so if that account still carries an individual’s name while the trust’s return claims the assets, the disagreement arrives in writing with a copy to the IRS.
What I actually see
The classification nobody wrote down. The attorney knows what the instrument says and is not asked. The preparer receives a PDF in March and infers an answer. I have seen the same trust treated as a grantor trust one year and as its own filer the next, with nothing in the file explaining the change, which is a hard position to defend if either year is examined.
The account name that contradicts the return. Assets sit in a custody account titled to an individual while the family, the instrument, and the return all treat the trust as owner. That gap used to persist for years. It does not anymore.
Basis abandoned at the boundary. Somebody sends the balance to the trust’s address without exporting the acquisition history from the sending venue first. Two years later the trust makes its first sale and the cost has to be reconstructed from an account that may no longer exist. The transfer takes four minutes, the export takes ten, and the ten gets skipped.
Here is the exercise I would set, and an afternoon covers it. Take the trust’s largest holding and produce four things in one sitting: the written reason it is treated as a grantor or non-grantor trust, the date and address at which the trust took control, when those particular units were bought and what they cost, and the name and taxpayer identification number on any account holding them. Whichever one you cannot produce today gets reconstructed under pressure next spring.
Where this goes wrong
The return gets prepared before anyone establishes what kind of taxpayer the trust is.
The specific failures: a grantor trust filing a Form 1041 it never needed, or a non-grantor trust filing nothing while income accumulates. Grantor treatment assumed to survive the grantor, so the year of death has no return. A custody account never retitled, so the information returns name an individual. Lot history left behind at a venue that later closes. Pre-funding and post-funding wallets merged into one spreadsheet, so the units can no longer be separated. And a distribution question nobody answered, which answers itself as accumulate at trust rates.
The decision rule
- Establish the classification in writing before the first year closes, from whoever drafted the instrument.
- Confirm the trust’s taxpayer identification matches the filing posture that classification produces.
- Retitle custody accounts into the trust, so information returns name the filer.
- Draw the funding boundary on a date, recording what moved, from which address, with the lot history.
- Keep each wallet as its own basis pool, since identification is done wallet by wallet.
- Split the straddle year into pre-funding and post-funding activity, since they sit in different accounting units.
- Answer the distribution question before year end and put the reason in the file.
- Reconcile every 1099-DA against the trust’s own records, resolving differences in writing.
Where this sits
Reporting is where the trust’s earlier decisions get priced. The authority to hold the assets sits underneath every line of the return. Trustee liability is what a reconstructed record exposes. The estate data room is where these documents belong, and the trusts and custody hubs sit above all of it.
Each part of this belongs to a different professional, and the handoffs between them are where trusts get filed wrong. The attorney knows whether the instrument creates grantor powers and rarely sees a return. The preparer sees the return and rarely reads the instrument. The custodian knows whose name is on the account and is asked by neither. All three can be right about their own piece while the trust files the wrong way, so name one person to hold the classification memo and check it against the information returns every year.
