Invoice Requirements in Switzerland: Legal Rules for 2026

TL;DR: Swiss MWST invoices require your UID/MWST number, sequential numbering, and rate-separated totals at 8.1% (standard), 2.6% (reduced), or 3.8% (accommodation). Switzerland is not in the EU but has bilateral arrangements -- retain invoices for at least ten years and prepare for growing e-invoicing adoption.

Swiss value added tax (MWST/TVA/IVA) is federal, administered by the Federal Tax Administration (FTA). Invoices must support input tax recovery for registered businesses and audit trails for domestic and cross-border supplies. Although Switzerland is not in the EU, place of supply rules for services and foreign platforms still require care. This overview targets 2026 practice; it is not legal advice. Confirm tourism, margin schemes, health, and financial exemptions with FTA guidance or your fiduciary. CHF rounding on cash registers should still tie to invoice lines so monthly VAT returns reconcile without manual journals.

Required fields

VAT invoices generally need supplier name and address, VAT number (UID/MWST) where registered, customer identification for B2B recovery, invoice date, unique number, description of goods or services, consideration split by rate, tax amounts, and total. Credit notes must reference the original invoice and adjust VAT clearly. Small-value simplified rules exist—verify current CHF thresholds in official publications before omitting buyer details.

Tax rules (VAT/GST/sales tax rates)

The standard VAT rate is 8.1% (subject to statutory schedules—confirm annually in FTA tables). A reduced 2.6% rate applies to certain everyday goods and services; a special 3.8% rate applies to accommodation services under defined conditions. Exempt supplies must not show recoverable VAT improperly. Exports and specific international services may be zero-rated with evidence requirements analogous to other jurisdictions. Mail-order distance sales into Switzerland may trigger foreign vendor registration duties—your customer-facing invoice must match import VAT stories at the border.

Language requirements

German, French, and Italian are all used in commerce depending on canton and customer; English is common in multinational B2B. Bilingual invoices reduce friction—keep legal names and UID consistent across languages.

Digital invoicing rules

Switzerland is moving toward broader electronic invoicing adoption, especially for B2G and large B2B buyers. Even where XML is not yet mandatory for your entity, immutable PDF archiving and structured ERP data ease future migration. Retain records for the statutory period in retrievable form. QR-bill and Swiss payment standards often sit beside VAT data—keep reference fields synchronised with banking files. Multi-entity groups should centralise UID validation so branch invoices never borrow sister company numbers.

Invoice numbering rules

Swiss VAT law requires invoices to carry a unique identifier that allows tracing within your records. There is no prescribed format, but the FTA expects sequential, traceable numbering that auditors can follow from issuance to MWST return. Common formats include year-based sequences (such as RE-2026-0001) or series by business division. You may maintain multiple series provided each is internally sequential and documented. Credit notes (Gutschriften) should carry their own identifiers and reference the original invoice. Businesses operating in multiple cantons or under multiple UID registrations should keep numbering distinct per registration. Gaps should be documented -- while Switzerland is less prescriptive than some EU neighbours, unexplained gaps combined with unexplained revenue fluctuations can prompt FTA inquiry. The QR-bill reference (QR-Referenz or Creditor Reference) that appears on the payment slip is a separate identifier from the invoice number -- keep both synchronised in your billing system.

Common exemptions and special cases

The MWST registration threshold is CHF 100,000 in annual worldwide revenue from taxable supplies. Businesses below this threshold are not required to register but may do so voluntarily. Certain entities (such as non-profit organisations and public bodies) have adjusted thresholds. Simplified invoicing applies for supplies below CHF 400 (including MWST) -- reduced content requirements allow omission of buyer details. Exempt supplies include health services (provided by qualified medical practitioners), educational services, cultural services, certain insurance and financial transactions, and letting of immovable property -- these must not show MWST. Saldosteuersatz (flat-rate method) allows qualifying businesses with annual tax liability under CHF 103,000 and annual revenue under CHF 5,005,000 to calculate MWST using sector-specific flat rates applied to gross revenue, simplifying return preparation. Exports are zero-rated (0%) with customs evidence requirements. Foreign businesses providing taxable services in Switzerland above CHF 100,000 annually must register for MWST regardless of whether they have a physical presence. The import tax on goods is collected at the border by the Federal Office for Customs and Border Security (BAZG) and is separate from the periodic MWST return -- align customs declarations with your invoice records. Switzerland is not in the EU, so intra-Community supply rules do not apply -- cross-border goods transactions with EU countries are treated as imports/exports.

Record retention requirements

Swiss law requires retention of business books and records, including invoices, for ten years from the end of the fiscal year in which the last entry was made. This applies to both issued and received invoices. Records must be stored in a manner that ensures legibility and accessibility for the full period. The Geschaeftsbücherverordnung (GeBüV) specifies requirements for electronic record-keeping: records must be stored on immutable media or with documented change-tracking, and the integrity and authenticity of the records must be verifiable. Paper invoices may be digitised if the scanning process meets the GeBüV standards, but the organisation must maintain a documented process description. Cloud storage is acceptable if the data can be accessed in Switzerland when required by the FTA. The ten-year retention period is one of the longest in Europe and requires careful planning when switching accounting systems or providers -- ensure migrated data remains accessible and complete for legacy periods.

E-invoicing status

Switzerland does not currently mandate structured e-invoicing for all B2B transactions. However, adoption is growing steadily. Swiss public-sector buyers increasingly require or prefer structured electronic invoices, and the Swiss QR-bill (which replaced the old payment slips in 2022) has modernised payment processing infrastructure. The eBill platform (operated by SIX) allows businesses to send structured invoices directly to customers' online banking, though this is more common for B2C. For B2B, Peppol adoption is increasing, with Swiss businesses participating through Austrian and other European Peppol access points. The Swiss government has signalled support for international e-invoicing standards and interoperability with EU frameworks. The Factur-X/ZUGFeRD hybrid format is gaining traction, particularly for Swiss businesses with German, French, or Austrian trading partners. While no mandate date has been announced, the direction of travel is toward structured e-invoicing -- businesses that prepare now will be ahead of the curve. The Swiss QR-bill and eBill infrastructure provide a foundation that could be extended to support mandatory e-invoicing in the future.

Penalties

The FTA may impose interest and sanctions for late payment, incorrect VAT, and inadequate invoices that block deductions. Interest on late-paid MWST accrues at 4% per annum (Verzugszins). Procedural violations (such as failure to keep records, late registration, or failure to comply with FTA requests) can attract fines of up to CHF 10,000 under the MWST law. Tax evasion (intentionally filing incorrect returns) carries fines of up to CHF 800,000 under the MWST-Gesetz, and in serious cases may be prosecuted under criminal tax fraud provisions of the Strafgesetzbuch (StGB) with fines and imprisonment. Unjustified showing of MWST on invoices (charging MWST when you should not) creates a tax liability for the shown amount -- you owe the FTA whatever MWST you printed on the invoice, even if the supply was exempt. The FTA may also issue estimated assessments (Ermessenseinschaetzung) when records are inadequate -- these assessments typically favour the FTA and shift the burden of proof to the taxpayer. Cross-border misclassification can trigger double taxation or refund delays in both Switzerland and the relevant EU member state.

Because Switzerland sits outside the EU VAT union, train accounts-payable staff to distinguish Swiss MWST footers from neighbouring EU VAT language -- mixed terminology on one PDF invites incorrect deduction attempts. Document FX sources when you invoice in foreign currency but report MWST positions in CHF so auditors can reproduce your conversion trail. When rates change, schedule a same-day template footer update rather than waiting for the next billing cycle.

FAQ

Is Switzerland part of the EU VAT system? No. Switzerland operates its own MWST system independently of the EU. There are no intra-Community supply rules -- goods moving between Switzerland and EU countries are treated as imports and exports with customs formalities. However, Switzerland has bilateral agreements with the EU that affect certain sectors. Swiss businesses selling to EU consumers may need to register for VAT in EU member states or use the EU's OSS system (though Switzerland is not part of OSS itself -- this applies when goods are shipped from EU warehouses).

What are the current MWST rates? The standard rate is 8.1%, the reduced rate is 2.6% (applicable to everyday goods like food, non-alcoholic beverages, books, newspapers, medicines, and agricultural inputs), and the special rate of 3.8% applies to accommodation services. These rates are set by statute and can change -- verify them against the latest FTA publication, as they have changed in recent years.

Do I need to register for MWST if I am based outside Switzerland? If your worldwide annual revenue from taxable supplies exceeds CHF 100,000 and you provide taxable services in Switzerland (even without a physical presence), you must register for MWST with the FTA. You may need to appoint a fiscal representative in Switzerland. This obligation applies to foreign businesses providing consulting, SaaS, and other services to Swiss customers.

How does the QR-bill relate to my invoice? The QR-bill is a standardised payment slip that accompanies your invoice (printed at the bottom or as a separate attachment). It contains payment information (IBAN, amount, reference number) encoded in a QR code that the payer's banking software can scan. The QR-bill is not the invoice itself -- it is a payment instrument. Your invoice must still contain all MWST-required fields. Ensure the QR-Referenz number and the invoice number are cross-referenced in your records so payments can be matched to invoices and MWST returns.
