Lifetime gifts, estate tax and gift tax basics for trusts

A U.S. citizen scenario

Consider a U.S. citizen contemplating a lifetime transfer to a trust for family beneficiaries. The initial questions concern what property will pass, what rights the citizen will retain and when beneficiaries can benefit. Federal gift tax can apply to transfers made directly or indirectly, including transfers in trust. Calling the arrangement a family trust does not settle its tax treatment.^[1]

A file of the proposed trust instrument, ownership records, valuation information and earlier gift tax returns gives advisers a common factual starting point. It also records the intended family use of the property and the administrative responsibilities that follow, without assuming a particular tax result.

U.S. treatment: identify the transfer and the taxpayer

Gift tax concerns a transfer for which the donor receives nothing or less than full value. A transaction can be a gift even when the donor does not describe it that way. A sale below full value or an interest-free or reduced-interest loan may create a gift, depending on the actual consideration and loan terms.^[2]

The IRS explains that residence for estate and gift tax purposes concerns domicile and can differ from residence for income tax purposes. Holding a green card does not conclusively establish U.S. domicile for estate and gift tax purposes.^[2]

The donor generally bears responsibility for gift tax, and a filing obligation can exist even when no tax is due. The recipient may have to pay if the donor does not pay. These distinctions make payment responsibility and return preparation separate items in the transaction checklist.^[1]

Annual exclusions and trust beneficiary rights

For gifts made in 2026, the annual gift tax exclusion is $19,000 per recipient. The IRS also lists $19,000 for 2025. The annual exclusion is distinct from the exclusion used in the broader lifetime gift and estate tax calculation.^[3][1]

Trust funding requires attention to the interest transferred. The 2025 Form 709 instructions state that future interests do not qualify for that year's $19,000 annual exclusion and require a return even below that amount. A contribution is therefore assessed by the beneficiary rights it creates, not simply by comparing its value with the annual figure.^[1]

For 2025 the basic exclusion amount was $13,990,000. For 2026 it is $15,000,000, and that amount also applies for the generation-skipping transfer tax exemption (Pub. L. 119-21, section 70106); it is indexed for inflation after 2026. For a gift to a spouse who is not a U.S. citizen the 2026 annual exclusion is $194,000. Each calculation is year-specific, and earlier gift tax returns trace lifetime use of the exclusion.^[1][4][6]

Gift reporting and generation-skipping transfers

Form 709 reports transfers subject to federal gift tax and certain generation-skipping transfer taxes, and it calculates any tax due. It also handles allocation of lifetime generation-skipping transfer exemption to lifetime transfers. The instructions require reportable gifts to be collected on the return for the corresponding calendar year.^[1]

Spouses cannot file a joint gift tax return. The 2025 instructions also require a return when spouses elect to split gifts, regardless of the amount. Marriage does not substitute for each spouse's individual filing analysis.^[1]

A trust intended to benefit successive generations deserves a separate discussion of generation-skipping transfer tax. The existence of a gift tax calculation does not complete the allocation work addressed by Form 709. Form 709 records how the transfer and any exemption allocation are treated.^[1]

Estate tax, lifetime gifts and portability

Estate tax uses fair market value and can include interests in trusts, insurance, business interests and property outside the United States. The estate tax calculation also takes account of lifetime taxable gifts. Moving property into a trust therefore calls for an analysis of both the lifetime transfer and the interests relevant at death.^[5][4]

For a U.S. citizen dying in 2026, Form 706 is required when the gross estate plus adjusted taxable gifts and the specific exemption exceeds $15,000,000. This is a filing test involving the combined items specified by the IRS, not a statement that the estate's current property value alone determines filing.^[4]

An executor must also file Form 706 to elect transfer of the deceased spouse's unused exclusion to a surviving spouse, regardless of estate size. The ordinary filing period is within 9 months after death, with an automatic 6-month filing extension available through Form 4768. Tax payment has its own requirements; more time to file does not resolve payment.^[4]

Federal, state and foreign questions are separate

State treatment requires a separate inquiry into the relevant state and its rules. The relevant states are those connected with the donor, the trust and the property.

Foreign treatment also requires a separate inquiry. A local exemption does not establish a U.S. exemption, and a foreign description of an arrangement cannot replace the U.S. transfer-tax analysis. The federal estate instructions expressly include property outside the United States in the gross estate discussion.^[4]

A foundation requires its own legal and tax analysis, and conclusions about a trust do not carry over by label. Engagement terms identify the work undertaken and the professional responsible for each conclusion.

Family office tax planning starts with records

The family office can maintain a transfer register recording the property, transfer date, recipient, governing documents and supporting valuation. The IRS gift tax guidance identifies appraisals, relevant transfer documents and explanations of unusual items among the records associated with gift reporting. These records help connect the legal documents with the tax return.^[3]

Income tax deserves its own workstream. The IRS explains that making a gift or leaving property to heirs does not ordinarily affect federal income tax, and personal gifts generally do not produce an income tax deduction.

A transfer is described by its documents, its valuation and its reporting position together. Signed documents, filed returns and payment records afterward belong to the same record as the transaction itself.

Scope and status

A family office label does not establish an investment adviser exclusion, a tax exemption or a reporting exemption. The SEC exclusion needs all three conditions: only family clients, wholly family-owned and family-controlled, and no holding out to the public as an investment adviser. An office serving unrelated families generally must register or find another exemption, and state law may apply.
