Art Collections Owned by Non-US Collectors: US Tax, Export and Provenance Rules

The issue

Unlike shares or land, a painting, a watch or a car changes its tax situs when it is moved. For a collector who is neither a US citizen nor domiciled in the United States, the federal estate tax applies to tangible property that is in the United States at death, at rates up to 40 percent, with a credit that shelters only USD 60,000. One work of moderate value is enough to require Form 706-NA, and museums, warehouses and auction houses will expect the IRS transfer certificate before they release anything.

Who the guide is for

The guide addresses collectors living outside the United States who keep, lend, store, sell or ship works there, and the relatives who will later deal with the collection. It covers art, jewelry, watches, cars and wine.

The treaties before the Code

The United States has estate tax treaties with fifteen countries, seven of which also cover gifts. The treaties with Germany, the United Kingdom, the Netherlands, Austria and Denmark permit taxation by the country of location only for real property and permanent establishment property, which leaves art to the collector’s country of domicile. The treaty with France lets the United States tax tangible movables located there (Article 7 of the estate tax treaty with France), with a proportionate credit and spousal relief. The older treaties keep the location rule, in most cases granting a proportionate part of the credit. No treaty protects a US citizen or binds the states, several of which tax a nonresident’s objects located there.

The museum-loan exemption and gifts made in the United States

A work counts as outside the United States if it was brought in solely for exhibition, is on loan to a public gallery or museum, and is on exhibition or in transit to or from it at the owner’s death (I.R.C. § 2105(c)). The gift tax has no such exception: a gift of an object located in the United States is taxable unless the donor’s treaty applies. Donors domiciled in Germany, the United Kingdom, Austria and Denmark are protected; a French donor is taxable but receives a French credit; Dutch, Swiss, Italian and Canadian donors have no gift tax treaty. A gift made after the object has left the United States is not taxed.

Storage, structures and valuation

Free ports in Geneva, Luxembourg and Singapore are beyond the US tax base because they are abroad; a bonded warehouse in Delaware is within it. A foreign holding company converts the objects into foreign shares, but its basis in them does not step up at the collector’s death. Placing an object in a revocable trust leaves it in the US estate if it was in the United States at the transfer or at death (I.R.C. § 2104(b)). Where an examined return values a single work at USD 50,000 or more, the IRS refers it to Art Appraisal Services, and works claimed above USD 150,000 generally go to the Art Advisory Panel; understatements of value attract penalties of 20 or 40 percent, and a Statement of Value may be obtained before filing.

Export licenses and provenance

Listed cultural objects above age and value thresholds need an EU license to leave the Union; Germany also requires a license for shipment to another member state above its own thresholds; France requires a certificate; Italy requires an attestato di libera circolazione for qualifying works above EUR 50,000 since April 14, 2026; the United Kingdom requires an individual license. National treasures may be refused export at any value. The Holocaust Expropriated Art Recovery Act of 2025, signed on April 13, 2026, removed the sunset of the 2016 Act, kept the six-year limitation period measured from the claimant’s actual discovery, and excluded time-based defenses as well as act of state and comity.

The questions the guide answers

• When is an object owned by a foreign collector US property for estate tax purposes?
• How do the estate and gift tax treaties treat a collector domiciled in Europe?
• What must be documented for a loaned work to qualify for the museum-loan exemption?
• When does handing over an object create US gift tax for a foreign donor?
• Which storage locations, ownership structures and valuation practices change the US position?
• Which export licenses are needed, and what does the amended HEAR Act mean for a work’s wartime history?
• What should the family do, and avoid, after the collector’s death?

The firm advises collectors and their families on the US side: the treaty position, the location of objects, the documentation of loans, gifts and shipments, valuation, Form 706-NA and the transfer certificate. European export, provenance and inheritance tax questions are coordinated with the collector’s advisors abroad or with advisors from the firm’s network.
