Cross-Border Metal Tax Risk in 2026: When a “Tax-Free” Sale Is Not Tax-Free in France, Belgium and Switzerland

A physical-metal transaction can be correctly priced, fully insured and held in a reputable vault while still producing an avoidable tax or reporting problem. The recurring failure is not usually a missing market quotation; it is an incorrect assumption that a metal’s commercial description, storage location or invoice label determines its tax treatment. For French-speaking private holders and family offices, the decisive evidence is the metal’s legal category, the seller’s tax residence, the transaction form and the documentary trail supporting acquisition, custody and disposal.

This guide addresses physical gold, silver, platinum and industrial or strategic metals held in France, Belgium or Switzerland. It is not personalised tax advice. Individual treatment depends on tax residence, ownership structure, transaction history and the applicable rules at the time of sale; a transaction file normally requires confirmation from a qualified tax adviser in the relevant jurisdiction.

Key points

• French taxe sur les métaux précieux (TMP) is a tax on gross sale proceeds or certain exports of gold, silver and platinum; it is not a tax on the actual gain.
• The French alternative capital-gains regime requires proof of the acquisition date and price, or proof that the item has been held for more than 22 years. A vault certificate alone establishes neither.
• The French capital-gains option for physical precious metals is a separate regime from the prélèvement forfaitaire unique (PFU) used for certain financial income. For metals in 2026, the relevant rate is 37.6% before any duration allowance — 19% income tax plus 18.6% social levies after the CSG increase enacted by the 2026 social-security financing law.
• “Investment gold” has a specific VAT definition. Silver, platinum and strategic metals do not become VAT-exempt merely because they are held as a store of value.
• Belgium’s 10% solidarity contribution on net capital gains has applied since 1 January 2026, and physical investment gold is expressly within scope, subject to a €10,000 annual allowance and the exclusion of gains accrued before 2026.
• A French tax resident does not acquire Swiss or Belgian tax-resident status by placing metal in a foreign vault or selling through a foreign counterparty. The vault address is a custody fact, not a tax status.

The first distinction: precious-metal tax rules are not strategic-metal rules

“Strategic metal” is a supply-chain and industrial term, not a universal tax classification. Copper, cobalt, lithium, nickel and similar materials may be strategically important to battery, defence or energy supply chains, but that commercial label does not place them within the French TMP. French tax law treats gold, silver and platinum as precious metals for the specific precious-metals tax regime; copper, cobalt and lithium do not fall within that category.

This distinction is especially important at purchase. An invoice for a kilogram of gold may support an acquisition under the investment-gold VAT exemption if the product meets the statutory conditions. An invoice for cobalt cathode, copper cathode or lithium chemical material is ordinarily an industrial-goods invoice. The relevant VAT treatment, import documentation, product specification and resale market are therefore different. A dealer’s use of phrases such as “investment-grade silver” or “strategic reserve metal” is not a substitute for the applicable VAT code, customs classification, assay specification and invoice treatment.

For portfolio construction, this is the first control point. Precious metals may sit in the same vault report as industrial metals, but they do not necessarily share the same tax logic on purchase, import, storage or sale. In practice, confusion often begins when a commercial storage platform presents all metals as a single “hard asset” category while the tax file requires a far narrower legal classification.

The operational consequence is straightforward. Once a product falls outside the precious-metals regime, the analysis usually moves back to ordinary VAT, customs treatment and the general rules applicable to movable property. That does not make strategic metals untaxable or simpler; it means they are governed by a different legal framework from bullion that qualifies for a specific precious-metals regime.

France: how the taxe sur les métaux précieux operates

For a French resident disposing of physical precious metals, the TMP is the central starting point. The tax is generally charged at 11.5% of the gross sale price: 11% TMP plus 0.5% CRDS. It applies to gold, silver and platinum, whether worked or unworked, and the calculation is based on the total consideration received rather than the gain realised. A sale at an economic loss can therefore still generate TMP.

For qualifying transactions, the seller may instead elect the capital-gains regime for movable property under Article 150 VL of the French General Tax Code. The taxable amount is then the actual gain, not the full sale price. The rate is 19% income tax plus social levies. Those levies rose from 17.2% to 18.6% when the 2026 social-security financing law (LFSS 2026, adopted in December 2025) raised the CSG on capital income from 9.2% to 10.6%. The combined 2026 rate is therefore 37.6% before any duration allowance, above the rate that applied in earlier years. The allowance is 5% for each year of ownership beyond the second year, producing full exemption after 22 years of ownership.

The election is operationally useful only where the seller can demonstrate either the acquisition date and acquisition price, or that the item has been held for more than 22 years. That second route matters for inherited or long-held bullion where the original invoice no longer exists but continuous holding can be evidenced. A generic statement that gold was “held for many years” satisfies neither test. Missing evidence commonly forces the analysis back toward the gross-proceeds TMP.

This distinction also matters because physical precious metals are not taxed under the ordinary PFU used for certain financial returns. A transaction memo that imports the PFU logic into a bullion sale is already using the wrong framework. The correct French choice is between the gross-proceeds TMP and the actual-gain regime, not between the TMP and a generic financial flat tax.

The evidence standard is practical rather than theoretical. A serious file contains the original purchase invoice, proof of settlement, a description identifying the item or bar, serial number where applicable, assay or refinery certificate, custody agreement and a continuous record of transfers between storage locations. A vault statement proves custody, not acquisition price, acquisition date or statutory eligibility for the capital-gains regime. Those are different evidentiary questions, and the French regime separates them sharply.

French forms follow the same split. The TMP declaration is made through Form No. 2091-SD, while the capital-gains option is exercised on Form No. 2092-SD. The purchaser or intermediary may have collection and filing obligations, but this does not eliminate the seller’s need to retain the evidence supporting the classification and any election.

Foreign storage adds a further layer. For a French resident, the TMP can become relevant on certain exports of precious metals, not only on a domestic sale. Some holders treat a transfer to a foreign vault as a logistics event, while French law can treat it as a taxable or reportable event requiring separate analysis of both the tax regime and the customs file.

VAT: investment gold is the exception, not the rule for all bullion

The VAT exemption applies to investment gold, not to every precious metal. Under the EU investment-gold regime, qualifying bars or wafers must meet the required purity threshold of at least 995 thousandths. Eligible coins must meet separate conditions, including minimum gold purity, a post-1800 date of minting, legal-tender status and a price not materially exceeding the gold value under the statutory test. France and Belgium implement this investment-gold exemption in their domestic VAT systems.

Silver bullion is not investment gold. Nor are platinum bars, palladium products or industrial strategic metals. A French purchase of physical silver is therefore not automatically VAT-exempt; the standard French VAT analysis is relevant unless a specific transaction rule applies. The same category issue arises in Belgium, where the standard rate is 21%, and in Switzerland, where the standard rate is 8.1%. The purchase invoice should state the exact metal, form, mass, purity, unit price, VAT treatment and seller identity. A document that describes silver as “VAT-free investment metal” without a lawful basis creates a direct audit and resale problem.

This is not a semantic point. VAT treatment affects entry cost, resale documentation and cross-border movement. For family offices that hold both monetary metals and supply-chain metals, a single custody platform can conceal multiple tax treatments. A vault statement may aggregate gold bars, silver coins and industrial metal lots in one valuation report, but the legal analysis still depends on each product’s own category. For audit purposes, classification has to be done line by line, not by storage provider or by portfolio marketing language.

France, Belgium and Switzerland: comparative treatment

The table is a screening tool, not a transaction approval memo. France taxes precious metals through a specific dual regime; Belgium now taxes the gain but only above an allowance and only for the post-2025 period; Switzerland distinguishes sharply between private asset management and commercial trading activity.

Belgium: an enacted gains tax, with two decisive carve-outs

Belgian investment gold continues to benefit from the EU-derived VAT exemption, subject to the product satisfying the legal definition of investment gold. That conclusion should not be extended to collectible coins, jewellery, silver bars or strategic metals. Coin classification deserves particular care: a numismatic premium, altered legal-tender status or failure to satisfy the investment-gold conditions can change the VAT analysis and the documentation required on resale.

VAT exemption, however, no longer means the gain is untaxed. Since 1 January 2026, Belgium levies a 10% solidarity contribution on annual net capital gains realised by private individuals on financial assets, and physical gold — bars and recognised investment coins such as Krugerrands, Maple Leafs, Napoléons and Vrenelis — is expressly within scope. Two features determine whether the tax actually bites:

• The annual allowance. The first €10,000 of net gains per year is exempt, with limited carry-forward of the unused portion (broadly up to €1,000 per year, capped around €15,000). For a household disposing of bullion in tranches, the allowance can absorb the entire liability.
• Historic gains are excluded. The contribution applies only to gains accrued from 1 January 2026. Appreciation up to 31 December 2025 is not taxed: the cost base is stepped up to the asset’s value at that date, with a transitional right in defined cases to elect the actual acquisition cost instead. For metal bought years ago, the taxable gain is therefore measured from a 2026 starting value, not from the original invoice price.

The practical consequence is that the 31 December 2025 valuation becomes a permanent file document. A holder who cannot evidence what the metal was worth on that date is likely to be arguing about the base rather than the rate. Beyond that, the analysis remains product-specific and holder-specific: whether the metal qualifies as investment gold, whether the seller is acting within normal private wealth management or professionally, and where the beneficial owner is resident. A French resident using Belgian storage still faces French residence analysis on sale, export or repatriation; Belgian custody simplifies EU logistics, not French tax status.

Switzerland: exemption depends on the holder, not on the vault address

Swiss federal tax law generally exempts capital gains on movable private assets for a private holder, while commercial trading activity is treated differently. The relevant question is therefore not whether bullion or strategic metals are stored in Switzerland, but whether the holder qualifies as a private investor under the applicable facts and is subject to Swiss taxation on that basis.

Swiss VAT treatment also remains product-specific. Investment gold benefits from exemption, while non-exempt metals require ordinary VAT analysis at the 8.1% standard rate. That is relevant for holders who place both monetary metals and industrial materials in Swiss storage on the assumption that the jurisdiction supplies a uniform tax result. It does not, and the same applies to strategic metals: Swiss storage changes logistics and insurance, not the legal classification of an industrial metal.

Cross-border movement adds its own formalities. A French export of precious metals requires attention to the TMP rules and to customs procedure, and movements can trigger declaration requirements, including at the €10,000 threshold in situations covered by the applicable customs regime. A vault operator’s receipt is not a customs declaration, an export declaration or a tax certificate.

The documentation that makes the tax position auditable

• Acquisition evidence: dated invoice, seller identity, proof of payment, quantity, purity and serial number or product identifier.
• Classification evidence: refinery assay, manufacturer specification, coin catalogue reference where relevant, and the VAT treatment stated on the invoice.
• Valuation evidence: for Belgian-resident holders, a defensible record of value at 31 December 2025 for assets held into the new regime.
• Custody evidence: allocated-storage agreement, vault location, inventory statement, insurance terms, transfer instructions and records of any movement between jurisdictions.
• Disposal evidence: sale contract, settlement statement, purchaser identity, gross proceeds, fees, applicable tax collection record and completed French tax form where required.
• Cross-border evidence: export, import and customs records where metal has crossed a border, especially between the EU and Switzerland.
• Ownership evidence: documentation identifying the beneficial owner, holding structure and any mandate under which the sale or transfer was executed.

The observable test is straightforward: the tax position should be reproducible from documents that identify the metal, prove ownership, establish acquisition cost and date, show where it was held, and record the legal route by which it was sold or moved. Where one of those links is absent, a claimed exemption, reduced rate or capital-gains election is not yet a complete compliance position. Tax frictions in physical metals rarely begin with market pricing; they begin when the file cannot demonstrate what was bought, where it was held, how it qualified for a given regime and which jurisdiction is entitled to tax the disposal.

Conclusion

A metal sale becomes “tax-free” only when the legal classification, residence analysis and documentary record support that result. France, Belgium and Switzerland do not tax physical metals on a single shared logic, and 2026 has moved two of the three: France’s actual-gain option now costs 37.6%, and Belgium taxes gold gains for the first time. For private holders and family offices, the decisive advantage lies less in geography than in a file that can survive scrutiny at the moment of sale.
