The affidavit layer, and what it squares with

Three of the five criteria run through somebody's status: an immediate family member, the individuals who collectively hold a majority interest in the entity that owns the property, and the sole beneficiary of a trust. Status is what this layer is for.

Where does the rule use them?

• Family relationship: marriage or birth certificates, or affidavits where a certificate is not available.
• Entity ownership: the organizational documents, plus an officer affidavit.
• Trust: the trust agreement, plus a trustee affidavit.

The tenant path is the exception. It runs on the lease and the tenant's own residency documents rather than on a sworn statement about them.

Three things the final rule settled

Entity and trust responses kept running into the same three questions, and the final rule answered them. They decide whether an affidavit is worth drafting at all:

• Sole beneficiary can be more than one person. Multiple individuals may collectively be the sole current beneficiaries of a trust, so a trust with two beneficiaries who both live there is not disqualified by the word sole.
• A contingent or future interest does not automatically disqualify. A remainder beneficiary in the document does not by itself defeat the current beneficiaries' claim.
• Multi-tier entity structures cannot establish primary residence. An entity owned by another entity does not reach an individual for this purpose, however many individuals sit at the end of the chain.

The third one is the one that ends filings. Where an LLC is held by a holding company, no affidavit fixes it, and the useful question becomes whether a different criterion fits: a tenant, or an immediate family member living there? Establish that before you draft anything. The two paths this layer serves are written out separately as entity-owned units and trust-held units.

What can an affidavit not do?

It cannot stand in for the base set. Whoever the qualifying resident is, that person's residency still has to arrive as ordinary documents: the most recent federal or state income tax return showing the address, or a driver's license or other DMV-issued identification on its own; if neither exists, a voter identification card plus one other proof. An affidavit that asserts residency with nothing behind it is asking DOF to take your word for it, and DOF does not have to.

The accuracy penalty is real

What does it have to square with?

1. The names in the affidavit appear in the organizational or trust documents.
2. The address in the affidavit is the property, written the same way it is written everywhere else in the file.
3. The residency documents behind it belong to the person the affidavit names.
4. The facts stated hold as of January 5, 2026, the taxable status date for the 2026-27 tax year.
