Does the United States recognise a UK hold-over relief claim?

No. A UK hold-over election has no effect on the US analysis. The US does not treat a lifetime gift as a realisation event, so there is no US gain to defer, and IRC section 1015 imposes a carryover basis automatically rather than by election. The donee therefore ends up with a reduced UK base cost and a separate, independently calculated US basis, and the two figures frequently differ.

Do I have to file Form 709 for a gift to my British wife?

Possibly. The unlimited marital deduction applies only where the recipient spouse is a US citizen. Under IRC section 2523(i), gifts to a non-citizen spouse qualify instead for a larger annual exclusion, indexed each year by the IRS. Transfers above that figure are reportable on Form 709 and consume lifetime exemption. Property transfers, joint account funding and mortgage repayments can all count, so the position should be reviewed annually.

Can my non-resident son claim UK hold-over relief on gifted shares?

No. TCGA 1992 section 166 denies section 165 relief where the transferee is not resident in the UK, and section 261 applies the same restriction to section 260. The donor would face an immediate UK capital gains charge at market value with no sale proceeds. Where a child has emigrated, the timing and structure of the transfer need to be reconsidered before anything is executed.

What happens if the donee leaves the UK after a hold-over claim?

A clawback can apply. Under TCGA 1992 section 168, if the donee ceases to be UK resident within the period specified in the legislation, the held-over gain becomes chargeable, and the charge falls on the donee rather than the original donor. Families whose children may study, work or settle abroad should treat this as a live contingent liability and confirm the current statutory period with HMRC guidance.

Is a gift from my UK parents taxable income in America?

No. The United States does not tax gifts as income in the hands of the recipient, and a nonresident alien donor is generally outside the US gift tax charge except on US-situs tangible property and real estate. However, a US person receiving a large gift from a foreign individual or estate must report it on Form 3520. The threshold is set out in the Form 3520 instructions, and penalties for non-filing are significant.

Does surviving seven years reduce my US gift tax exposure?

No. The seven-year rule is a UK inheritance tax concept applying to potentially exempt transfers. The US system has no survivorship element: a completed gift above the annual exclusion permanently reduces the donor's basic exclusion amount and is brought back as an adjusted taxable gift in the estate tax computation at death. A gifting programme designed purely around the UK seven-year rule can be inefficient for a US donor.

UK Gift Hold-Over Relief vs US Gift Tax Rules

UK gift hold-over relief allows a donor to give away qualifying business assets, or to settle property on trust, without paying capital gains tax at the point of transfer; the gain is instead deferred by reducing the recipient's base cost. The United States has no equivalent election. A lifetime gift by a US person is not a realisation event for US income tax at all, but it consumes lifetime gift and estate tax exemption, requires a gift tax return, and passes the donor's basis to the donee under the carryover basis rule. Where one family straddles both systems, the two mechanisms do not align, and the mismatch can produce real double taxation years later when the asset is finally sold.

What is UK gift hold-over relief and when can you claim it?

There is no gift tax on UK lifetime transfers, but there is a capital gains charge. Under TCGA 1992 section 17, a disposal to a connected person is treated as made at market value, so a parent who gives shares to a child is taxed as though the shares had been sold, despite receiving nothing. Hold-over relief is the statutory answer to that cash-flow problem, and HMRC's Capital Gains Manual sets out the conditions in considerable detail.

Section 165 provides the relief for gifts of business assets. Both donor and donee must normally join in the claim, made on the form attached to HMRC Helpsheet 295, within the statutory time limit. Where the transferee is the trustee of a settlement, the transferor claims alone. The relief is not automatic: without a valid and timely claim, the gain crystallises in the tax year of the gift and becomes payable in the ordinary way.

Assets used in a trade, profession or vocation carried on by the donor
Assets used in the trade of the donor's personal company, as that term is defined in the legislation
Shares or securities in an unlisted trading company, or in the holding company of a trading group
Shares in the donor's personal company, including certain quoted holdings
Agricultural property qualifying for agricultural property relief

Relief does not remove the gain; it moves it. The donor's chargeable gain is reduced to nil, or by a restricted amount where consideration is received, and the donee's acquisition cost is reduced by the same figure. In economic terms the donee acquires the asset at broadly the donor's historic cost rather than at market value, and carries the donor's latent gain forward until an eventual disposal.

Relief is restricted where the shares given away are in a company holding substantial non-business assets, so that only the business proportion of the gain is held over. Investment property, surplus cash and let land can each dilute a claim. HMRC's guidance and the practical commentary published by the CIOT and ICAEW both stress that the composition of the balance sheet at the date of the gift, rather than the company's general description of itself, determines the outcome.

How does section 260 hold-over relief differ from section 165?

Section 260 applies where the gift is an immediately chargeable transfer for inheritance tax purposes rather than a potentially exempt transfer. The classic case is a settlement of assets on a discretionary or other relevant property trust. Because the transfer already attracts an inheritance tax charge, the legislation permits the capital gains tax to be deferred, avoiding two taxes falling on a single event that generates no cash.

The important practical difference is asset scope. Section 165 is confined to business and agricultural property; section 260 is not, so an investment portfolio, an interest in land or a non-trading company can be settled with the gain held over, provided the inheritance tax analysis supports it. This is why so much UK family planning is built around relevant property trusts rather than outright gifts of investment assets.

Section 260 also carries anti-avoidance limits. Relief is denied where the settlement is one in which the settlor retains an interest, and further provisions counter arrangements designed to obtain a hold-over followed by an uplift. HMRC's manuals set out the tests, and they should be read alongside the settlor-interested trust rules before any transfer is documented or any deed is executed.

Relief can also apply when property leaves a relevant property trust and an inheritance tax exit charge arises, allowing trustees to appoint assets to a beneficiary without a simultaneous capital gains charge. That is a common route for passing family company shares to the next generation, and it is precisely the point at which a US-connected beneficiary creates complications that UK-only advice will not anticipate.

Does the United States offer anything equivalent to hold-over relief?

No. The United States does not treat a gift as a realisation event for income tax purposes, so there is no gain to defer and no election to make. A US donor who gives appreciated stock recognises nothing on the transfer itself. The consequence is that the two systems reach a superficially similar cash-flow outcome by wholly different routes, and the differences matter greatly once the routes are compared in detail.

Instead of an election, the US applies a mandatory carryover basis rule under IRC section 1015. The donee takes the donor's adjusted basis, increased in limited circumstances by gift tax attributable to the appreciation. Where the property is worth less than the donor's basis at the date of gift, a separate rule governs the calculation of a later loss. IRS Publication 551 explains the mechanics of both.

What the US does tax is the transfer itself. Gifts above the annual exclusion consume the donor's basic exclusion amount, are reported on Form 709, and any excess beyond the lifetime figure is charged to gift tax under the unified rate schedule. The annual exclusion and the basic exclusion amount are indexed for inflation, and the current figures are published each year by the IRS in its annual inflation adjustment revenue procedure.

At death the systems diverge sharply. The US gives a basis adjustment to fair market value under IRC section 1014, which is why deferring transfers until death can be attractive for US income tax purposes. The UK gives a capital gains uplift on death but charges inheritance tax on the estate. A held-over gain sitting in a donee's reduced base cost simply disappears if the donee dies still owning the asset.

What happens to base cost when a US person receives a held-over gift?

Assume a UK parent gives shares in the family trading company to a child who is a US citizen living in London. A section 165 claim removes the UK gain from the parent and reduces the child's UK base cost. For US purposes there is no gain on the gift, and the child takes the parent's US basis. Superficially the two answers agree; in practice they rarely produce the same number.

The US basis must be computed in US dollars, using the exchange rate applicable when the donor acquired the asset, and adjusted under US rules for depreciation, capital contributions and prior distributions. The UK base cost is a sterling figure computed under UK rules, potentially reflecting rebasing to March 1982 and other UK-only adjustments. Two currencies and two adjustment histories produce two different gains on the same disposal.

Exchange rate movement between acquisition and disposal, creating US gain with no UK counterpart
March 1982 rebasing and other base cost adjustments available only under UK law
Different treatment of enhancement expenditure, capital allowances and depreciation
US basis adjustments arising from an earlier death of a spouse, or from partnership and S corporation activity
Share reorganisations, part-disposals and rollovers characterised differently under each code

The direction of travel is usually unfavourable. Hold-over relief deliberately pushes the UK gain onto the donee, while the US carryover rule does the same thing independently. The donee therefore holds an asset with two low base costs and, on a later sale, faces a UK charge and a US charge computed on different figures, in different currencies, and potentially in different tax years because the UK and US tax years do not coincide.

That last point is where relief most often fails. Credit relief depends on the same gain being taxed by both countries in periods that permit a credit to be claimed. A UK disposal in February falls in one UK tax year and one US calendar year, but a disposal shortly after 5 April splits them, and the foreign tax credit rules in IRC section 901 and the instructions to Form 1116 must then be applied with real care.

How do potentially exempt transfers and the seven-year rule compare with US gift tax?

A UK gift from one individual to another is normally a potentially exempt transfer. No inheritance tax is due at the time, and if the donor survives seven years the transfer falls out of account entirely. If the donor dies within that period the gift becomes chargeable, with tapering of the tax where death occurs between three and seven years after the gift, subject to the nil rate band available at that point.

A transfer into most trusts is treated differently. It is an immediately chargeable transfer, taxed at the lifetime rate on value above the available nil rate band, with further periodic and exit charges under the relevant property regime. GOV.UK guidance and HMRC's Inheritance Tax Manual set out the calculation, and the interaction with earlier chargeable transfers made in the preceding seven years is easily overlooked in a family with a long gifting history.

The US has no survivorship concept whatsoever. Every completed gift above the annual exclusion is reported and permanently reduces the donor's remaining exemption, regardless of how long the donor lives afterwards. Adjusted taxable gifts are then brought back into the estate tax computation at death. Surviving seven years achieves nothing for US purposes; exemption once used is used for good.

This produces a recurring planning tension. A programme of substantial lifetime gifts is efficient for UK inheritance tax if the donor survives the period, but for a US donor the same programme steadily consumes an exemption whose future level is subject to legislative change and which cannot be recovered. Where one spouse is a US person and the other is not, deciding which of them makes each gift is often the single most valuable decision in the plan.

The UK inheritance tax position also changed from April 2025, when the connecting factor moved away from domicile towards long-term UK residence. Whether an individual's non-UK assets fall within the UK net now depends on their residence history rather than on domicile. The precise test and any transitional provisions should be confirmed against current GOV.UK guidance rather than assumed from an analysis prepared under the previous rules.

What are the rules on gifts to a non-citizen spouse?

The unlimited US marital deduction applies only where the recipient spouse is a US citizen. IRC section 2523(i) denies it for a non-citizen spouse and substitutes a larger annual exclusion, indexed for inflation and published by the IRS each year. A US citizen who transfers a substantial asset to a British spouse can therefore make a taxable gift, where the identical transfer between two US citizens would be entirely free of gift tax.

The UK spouse exemption from inheritance tax was historically limited where the recipient spouse was not UK domiciled, with an election available to be treated as domiciled. Following the move to a residence-based system, the relevant test has changed, and the current position and any election should be checked on GOV.UK rather than assumed. Capital gains transfers between spouses living together remain on a no gain, no loss basis.

Everyday transactions are the usual source of trouble. Adding a spouse to the deeds of a London house, funding a joint investment account, repaying a spouse's borrowing, or transferring a company shareholding for UK reasons can each be a completed gift for US purposes. Gift splitting under IRC section 2513, which allows a married couple to treat gifts as made half by each, is unavailable where one spouse is neither a US citizen nor a US resident.

Where the intention is to leave assets to a non-citizen spouse at death, the qualified domestic trust rules provide a deferral mechanism, but that is an estate tax solution and does not assist with lifetime transfers. Lifetime gifting to a non-citizen spouse must therefore be sized against the special annual exclusion, or funded deliberately out of exemption with the consequences understood in advance.

When is UK hold-over relief unavailable because of the donee's residence?

Hold-over relief is denied where the transferee is not resident in the UK. TCGA 1992 section 166 blocks section 165 relief in that case, and section 261 does the same for section 260. This is the provision that most often defeats a plan to pass family company shares to a child who has moved to New York, because the deferral is simply unavailable and the donor faces an immediate UK charge with no sale proceeds to fund it.

There is also a clawback where the donee emigrates after the gift. If the donee ceases to be UK resident within the period specified in TCGA 1992 section 168, the held-over gain is charged, and the charge falls on the donee rather than on the original donor. For an internationally mobile family this converts a settled UK position into a contingent liability attached to the next generation's career decisions.

Treaty analysis does not rescue the position. The US-UK double taxation convention allocates taxing rights over gains, but it does not create a UK deferral that domestic law withholds. Where a donee is treaty-resident elsewhere, the residence condition in the hold-over provisions can still fail. Documented residence status at the date of transfer, and a realistic view of future mobility, should precede any claim.

How are gifts into trust taxed on both sides of the Atlantic?

On the UK side, a settlement of assets on a relevant property trust is an immediately chargeable transfer for inheritance tax, with a section 260 hold-over usually available for capital gains. The trust then sits within the periodic and exit charge regime, and the settlor-interested rules must be reviewed, because they can both deny hold-over relief and attribute trust gains and income back to the settlor personally.

On the US side the analysis is quite different. If the settlor is a US person and any beneficiary is, or may become, a US person, IRC section 679 can treat a non-US trust as a grantor trust, so all income and gains remain taxable to the settlor. Transfers of appreciated property by a US person to a foreign trust can also trigger gain recognition under IRC section 684 in defined circumstances.

For US beneficiaries of non-grantor foreign trusts, accumulated income becomes undistributed net income, and later distributions are taxed under the throwback rules with an interest charge. A perfectly ordinary UK discretionary trust, holding UK assets and administered by UK trustees, can therefore be an expensive structure for a single US grandchild, even where the UK inheritance tax and capital gains outcome is excellent.

Form 3520 for transfers to, and distributions from, a foreign trust
Form 3520-A, the annual information return of a foreign trust with a US owner
Form 8938 under the Foreign Account Tax Compliance Act where the thresholds are met
FinCEN Form 114, the FBAR, where a US person has an interest in or authority over non-US accounts
Registration of the trust with HMRC's Trust Registration Service

What US reporting applies to cross-border family gifts?

Form 709, the United States Gift (and Generation-Skipping Transfer) Tax Return, is required from a US donor whose gifts to any one individual exceed the annual exclusion, and in other defined cases such as gifts of future interests or an election to split gifts. It is due by the normal filing date for the individual income tax return, with an extension available, and filing starts the limitation period on the reported valuation.

A US person who receives a large gift from a non-US individual reports it on Form 3520. No tax is due; the obligation is purely informational. The reporting threshold for gifts from a nonresident alien individual or a foreign estate is set out in the instructions to Form 3520, with a lower indexed threshold applying to gifts from foreign corporations and partnerships. Penalties for late filing are calculated by reference to the value of the gift.

Two further rules deserve attention. Gifts and bequests received by a US person from a covered expatriate can be taxed to the recipient under IRC section 2801 and reported on Form 708. Separately, a donor who is a nonresident alien is subject to US gift tax only on US-situs tangible property and real estate; intangibles such as shares in US corporations fall outside the charge, which is a planning point of considerable value.

Valuation is the practical battleground. Gifts of unquoted shares require a defensible valuation for both UK inheritance tax and US gift tax, and the two authorities apply different discount conventions. A single valuation report prepared without regard to both regimes tends to satisfy neither, and it is adequate disclosure on Form 709 that starts the US limitation period running on the figure reported.

Can foreign tax credits solve the eventual double taxation?

Sometimes, but not reliably. The credit mechanism in IRC sections 901 and 904, claimed on Form 1116, requires the foreign tax to be creditable, to be paid by the person claiming the credit, and to be matched to foreign source income in the correct category and period. A held-over gain later charged to UK capital gains tax on the donee can fail one or more of those conditions.

Source is the first obstacle. Gains on personal property are generally sourced by reference to the seller's residence under IRC section 865, subject to an exception for sellers with a tax home outside the United States who pay foreign tax at a specified minimum rate. Where the gain is US source, no credit is available without resourcing under the relief from double taxation article of the US-UK double taxation convention.

The second obstacle is the treaty framework itself. Income tax and capital gains matters sit in one convention; inheritance tax, gift tax and generation-skipping transfer tax sit in the separate US-UK estate and gift tax treaty. The two do not interlock, so a UK inheritance tax charge on a chargeable lifetime transfer and a US gift tax charge on the same transfer are relieved, if at all, only through the estate and gift treaty.

The practical answer is to model the exit before making the gift. Project the eventual disposal in both currencies, in both tax years, in the hands of the intended owner, and ask whether a credit will genuinely be available in the year the second tax falls due. If it will not, the deferral obtained by a hold-over claim may have been bought at the price of a permanent double charge.

What planning approaches work for cross-border families?

Start by asking whether a hold-over claim is right at all. The claim is elective. Where the donor has capital losses, an unused annual exempt amount or access to a lower rate, crystallising some or all of the gain now can leave the donee with a higher UK base cost and a cleaner future position, particularly where the donee is a US person whose US basis will remain low in any event.

Identify which family members are US persons, and which may become US persons through marriage, study or relocation
Decide which spouse should make each gift, taking account of the exemptions each of them has available
Test the donee's UK residence before the transfer, because non-residence defeats hold-over relief entirely
Consider whether a trust is genuinely required, or whether an outright gift avoids the foreign trust regime
Prepare a single valuation package capable of supporting both Form 709 and the UK inheritance tax account

Sequencing matters as much as structure. Gifting business property before a US-connected child returns to the UK, or before a US person joins a class of trust beneficiaries, often produces a materially better result than the same transaction a year later. Equally, deferring a gift until after a planned change of residence can turn an immediate UK charge into a deferred one, or the reverse.

Keep contemporaneous records. The held-over gain figure, the donee's reduced UK base cost, the donor's US basis and the exchange rates applied should all be recorded at the time and retained. These figures may not be needed for twenty years, and reconstructing them after a family company has been reorganised twice is expensive and frequently impossible.

What should you do next?

Before any transfer is signed, obtain a written analysis covering four questions: whether hold-over relief is available and desirable, what the UK inheritance tax consequence is, what the US gift tax and reporting consequence is, and what the base cost position will be in each country afterwards. Board minutes, stock transfer forms and trust deeds should follow that analysis rather than precede it.

Where advice is fragmented between a UK accountant and a US preparer, the mismatch described here is exactly what falls between them. Speaking to a dual-qualified US-UK adviser who can read TCGA 1992 and the Internal Revenue Code together, and who is familiar with HMRC's manuals, the IRS instructions to Forms 709 and 3520, and both bilateral treaties, is the most reliable way to ensure a lifetime gift achieves what the family actually intends.
