Swiss Stamp Duty: Issuance, Transfer & Premium Tax

Switzerland levies three distinct stamp duties (Stempelabgaben) administered by the Swiss Federal Tax Administration (ESTV): the issuance stamp (Emissionsabgabe) on capital contributions, the securities transfer stamp (Umsatzabgabe) on securities transactions, and the insurance premium stamp (Versicherungsabgabe). Each affects different transactions and has its own rate, exemptions, and planning implications.

1. Issuance Stamp Tax (Emissionsabgabe)

What It Is

The issuance stamp tax applies to the creation and increase of equity capital in Swiss companies. It is a federal tax levied at 1% of the consideration received for newly issued shares or quota capital.

Who It Affects

Swiss AG, GmbH, and certain cooperative entities issuing new shares or increasing their share capital. It applies to:

• Initial share capital on company formation
• Capital increases (rights issues, new share subscriptions)
• Conversion of loans or reserves into share capital
• Premium contributions (Agio) received above nominal value

Exemption: CHF 1 Million Threshold

The most important practical exemption: the first CHF 1 million of paid-in capital is exempt from issuance stamp tax. This means:

• A Swiss AG formed with CHF 100’000 share capital: zero issuance stamp tax
• A Swiss GmbH formed with CHF 20’000 share capital: zero issuance stamp tax
• A capital increase from CHF 100’000 to CHF 800’000: zero issuance stamp tax (still within CHF 1 million total)
• A capital increase that takes total paid-in capital above CHF 1 million: 1% on the excess above CHF 1 million

This exemption covers the vast majority of SME formations and many smaller capital rounds.

Rate and Calculation

1% on the contribution amount above the CHF 1 million exemption.

Example: A Swiss AG increases its capital from CHF 500’000 to CHF 3’000’000 (a CHF 2’500’000 increase). Total paid-in capital after the increase: CHF 3’000’000. Exempt amount: CHF 1’000’000. Taxable: CHF 2’000’000. Issuance stamp: CHF 20’000.

Abolition of Issuance Stamp on New Equity (2023)

Switzerland abolished the issuance stamp for new equity capital contributions as of 1 January 2023 — but only for certain qualifying capital contributions, particularly in the context of startup financing. The full exemption rules are technical; the CHF 1 million base exemption remains the primary practical tool for most transactions.

2. Securities Transfer Stamp Tax (Umsatzabgabe)

What It Is

The securities transfer stamp tax applies to the purchase and sale of qualifying securities when a Swiss securities dealer is party to or acts as intermediary in the transaction.

Rate

0.15% on transactions involving Swiss securities; 0.30% on transactions involving foreign securities. The tax is split between buyer and seller (each pays half of the applicable rate).

Who Is a “Swiss Securities Dealer”

The tax is triggered when a Swiss securities dealer (Effektenhaendler) is involved. This includes:

• Swiss banks
• Swiss securities firms (broker-dealers)
• Any Swiss company whose securities business meets the statutory threshold (broadly, companies that regularly trade securities with more than 10 counterparties per year and hold a securities book of more than CHF 10 million)

Direct private transactions between two non-dealers are not subject to the securities transfer stamp.

Exemptions

Key exemptions from securities transfer stamp:

• Swiss government bonds (Eidgenoessische Anleihen)
• Units in Swiss collective investment schemes (funds)
• Money market instruments with maturity under 12 months
• Intragroup transfers between qualifying group companies (group exemption)
• Market maker exemptions for qualifying dealers
• Foreign collective investment schemes

Practical Impact

The securities transfer stamp is relevant for:

• Swiss banks executing client securities trades
• Companies buying or selling significant blocks of shares involving a Swiss dealer
• M&A transactions where shares change hands via a Swiss dealer

For private company share transfers (sale of GmbH quota or non-listed AG shares) between private parties without bank intermediation, the stamp typically does not apply. This distinction is relevant when acquiring a shelf company or completing a private share sale.

3. Insurance Premium Stamp Tax (Versicherungsabgabe)

A 5% stamp tax applies to non-life insurance premiums for risks located in Switzerland. Life insurance is exempt. The insurer is liable but passes the cost to the insured through the premium. This is relevant for Swiss companies purchasing Swiss commercial insurance policies.

The CHF 1 Million Surprise: When Stamp Duty Catches Founders Off Guard

Most founders forming a Swiss GmbH with CHF 20’000 or an AG with CHF 100’000 never encounter stamp duty. The CHF 1 million exemption covers them entirely. The surprise hits at the first serious capital increase.

The pattern we see repeatedly: A startup raises a Series A round of CHF 5 million. The investors contribute CHF 5 million in exchange for new shares. Total paid-in capital after the round: CHF 5.1 million. Stamp duty: 1% on CHF 4.1 million (the amount above CHF 1 million) = CHF 41’000. This is due within 30 days of the commercial register entry. The founders budgeted for legal fees, notary costs, and share premium — but not for a CHF 41’000 federal tax bill that arrives weeks after closing.

The conversion trap: A founder loans CHF 2 million to the company during the early years. When the company stabilises, the board converts the loan to share capital. If total equity after conversion exceeds CHF 1 million, the conversion triggers issuance stamp duty on the excess — even though no new cash entered the company. The conversion is economically neutral but fiscally expensive.

Case study: A fintech company in Zug raised CHF 8 million across three funding rounds. Round 1 (CHF 500’000) and Round 2 (CHF 1.2 million) were structured partly as convertible loans to stay within the CHF 1 million stamp duty exemption for as long as possible. Round 3 (CHF 6.3 million) converted all prior loans and issued new shares, taking total paid-in capital to CHF 8 million. Stamp duty on CHF 7 million above the exemption: CHF 70’000. By timing the conversions to coincide with the final equity round rather than converting incrementally, the company paid stamp duty once instead of across multiple events — though the total amount was identical. The real saving came from structuring CHF 2 million of the Round 3 capital as a subordinated shareholder loan rather than equity, reducing the stamp duty base by CHF 2 million and saving CHF 20’000.

Planning Points

Issuance stamp and holding structures: When a Swiss holding company contributes equity to a Swiss subsidiary, the subsidiary’s share capital increase triggers issuance stamp on amounts above CHF 1 million. For large capitalisation scenarios, this is a material cost to plan around — inter-company loan structures may be more efficient above threshold.

A practical illustration: A Swiss holding AG capitalises a new operating subsidiary with CHF 3’000’000 in share capital. The first CHF 1’000’000 is exempt. The remaining CHF 2’000’000 attracts 1% issuance stamp: CHF 20’000 payable to the ESTV within 30 days. For a multi-entity holding structure with three or four subsidiaries each capitalised above the threshold, the aggregate stamp liability can reach CHF 50’000-100’000 — a cost that is entirely avoidable through proper structuring (shareholder loans, agio management, or staged capital increases timed to coincide with actual capital needs).

The CHF 1’000’000 exemption applies per entity, which means a holding group with four Swiss subsidiaries benefits from CHF 4’000’000 in aggregate exempt capital — provided each entity is properly structured. This is one of the few areas where having multiple Swiss entities produces a direct tax saving.

Securities transfer and share sales: In M&A transactions involving private Swiss companies, structuring the transaction to avoid Swiss securities dealer involvement (direct buyer-seller transfer without bank intermediary) can eliminate the securities transfer stamp. Legal and tax advice is needed to confirm applicability in each transaction.

Group exemption: Swiss corporate groups can access an intragroup exemption from securities transfer stamp for qualifying share transfers within the group. Requires formal application to ESTV.

Withholding tax interaction: Stamp duties are separate from Swiss withholding tax on dividends (35%). Both may apply in different stages of a corporate restructuring — capital increase (stamp duty) followed by dividend distribution (withholding tax). Coordinated planning is essential for larger transactions.

Frequently Asked Questions

Is the 1% stamp duty really unavoidable on large capital increases?

The 1% rate is statutory and cannot be negotiated. However, structuring alternatives exist: shareholder loans instead of equity (within thin capitalisation limits), agio structuring, and qualifying reorganisation exemptions under the Federal Stamp Duties Act. For group restructurings — mergers, demergers, and intragroup asset transfers — specific exemptions can eliminate stamp duty entirely if the conditions are met. These conditions are technical and must be confirmed with the ESTV before the transaction.

Why do some companies pay CHF 0 in stamp duty while others pay CHF 100’000?

The CHF 1 million exemption applies per entity. A company that stays at or below CHF 1 million in total paid-in equity pays zero. A company that raises CHF 11 million pays 1% on CHF 10 million = CHF 100’000. The difference is entirely a function of how much equity capital is contributed. Shareholder loans, convertible instruments that remain as debt, and group financing structures can all reduce the equity base subject to stamp duty — but each must comply with Swiss thin capitalisation rules to avoid the loan being reclassified as hidden equity.

Do I pay issuance stamp when forming a Swiss GmbH with CHF 20’000 capital?

No. The CHF 1 million exemption covers the entire CHF 20’000. Zero stamp tax on formation.

Is there stamp duty on the sale of private company shares in Switzerland?

Securities transfer stamp only applies when a Swiss securities dealer is involved in the transaction. A direct private sale of GmbH quota or unlisted AG shares between two private parties without a bank dealer typically does not attract the stamp.

Does the securities transfer stamp apply to crypto assets?

The application of securities transfer stamp to crypto assets depends on whether the token constitutes a qualifying security under Swiss law (particularly for asset tokens / investment tokens). Payment tokens and utility tokens are generally not subject to stamp. Asset tokens that qualify as securities may be — this requires specific analysis by reference to FINMA’s token classification.

How is issuance stamp tax reported and paid?

The company issuing the shares is liable for the issuance stamp. It must file a declaration with the ESTV within 30 days of the capital increase becoming legally effective (typically the date of commercial register entry). Payment is due within 30 days of the filing. Late payment attracts interest.

Does the issuance stamp apply to shareholder loans converted to equity?

Yes. When a shareholder loan is converted into share capital, the conversion amount is treated as a capital contribution and subject to issuance stamp tax on amounts above the CHF 1 million exemption threshold. The same applies to the capitalisation of reserves.

Are there stamp duty implications for capital deposit accounts?

The capital deposit account itself does not trigger stamp duty. The stamp duty event is the formal capital increase registered with the Commercial Register. The deposit account is simply the mechanism for holding funds until the formation or capital increase is completed.

Is the CHF 1 million exemption per company or per group?

The CHF 1 million exemption applies per company. Each Swiss legal entity has its own exemption threshold. A group with multiple Swiss subsidiaries benefits from a separate CHF 1 million exemption for each entity.

Do stamp duties apply to cooperative formations?

Cooperatives (Genossenschaften) are subject to issuance stamp on the issuance of cooperative shares (Genossenschaftsanteile) under the same rules as AG and GmbH capital contributions. The CHF 1 million exemption applies equally.

Can stamp duty be reclaimed or offset?

Swiss stamp duties are final federal taxes. They cannot be reclaimed, offset against other taxes, or credited against corporate tax obligations. They are, however, deductible as a business expense for corporate income tax purposes.

What stamp duty applies when restructuring a Swiss group?

Qualifying group restructurings — mergers, demergers, and asset transfers between group companies — may benefit from stamp duty relief under the Federal Stamp Duties Act reorganisation provisions. Both issuance stamp and securities transfer stamp exemptions are available for qualifying restructurings, but the conditions are specific and must be confirmed with the ESTV before the transaction is executed.
