Last updated: 2026-08-27 Compliance model: Two regimes at once. Swiss VAT law governs by treaty, through Liechtenstein's own VAT Act and its own tax administration, so there is no B2B or B2C mandate and none in prospect. Public procurement is inside the EEA Agreement, so contracting authorities must accept EN 16931 invoices — a duty to receive, not to send.
🇱🇮Liechtenstein has no e-invoicing mandate on any business. Its contracting authorities have had to accept and process EN 16931 electronic invoices since 27 November 2018, but no supplier is obliged to send one, there is no national platform, and no authority receives invoice or transaction data. VAT returns have gone through the eMWST portal since January 2025, which is a filing channel and not a reporting regime.
E-invoicing mandate
B2GVOLUNTARYAuthorities must accept EN 16931 invoices for procurement above EU thresholds since Nov 2018. Suppliers may send them; they need not.
B2BNO MANDATENo B2B mandate and none announced. The VAT Act sets invoice contents but no format, and EU VAT law does not reach the EEA.
B2CNO MANDATENo B2C mandate. Nothing in the VAT Act or its ordinance imposes an electronic form on a consumer invoice.
NO MANDATE
E-reporting
None. VAT returns go through the eMWST portal, mandatory since January 2025, but carry no invoice or transaction detail.
10 yrs
Archiving
Ten years under the PGR and the VAT Act, twenty for immovable property. Electronic retention is allowed if records stay unalterable.
NOT REQUIRED
Digital signature
Not required. The ordinance names digital signatures as one example of assuring integrity, among others -- never as a duty.

01
Compliance timeline
Liechtenstein's timeline is short because its obligations are few, and the one that matters arrived by an unusual route. Directive 2014/55/EU was incorporated into the EEA Agreement by Joint Committee Decision 166/2015, in force on 1 January 2016, with an EEA compliance date of 27 November 2018. Everything since has been administrative rather than substantive.
2016
2016-01-01In effect
EEA Joint Committee Decision 166/2015 brings the EU e-invoicing directive into the EEA Agreement
Decision 166/2015 of 11 June 2015 incorporated Directive 2014/55/EU into Annex XVI of the EEA Agreement, entering into force on 1 January 2016. Liechtenstein notified fulfilment of its constitutional requirements on 19 November 2015. This is the route by which a non-EU state acquired a European e-invoicing obligation.
2018
2018-11-27In effect
Contracting authorities must accept and process EN 16931 electronic invoices
The EEA compliance date for Directive 2014/55/EU. Liechtenstein's contracting authorities must receive and process electronic invoices conforming to the European standard for procurement above EU thresholds. The duty is on the authority to receive, not on the supplier to send: issuing electronically remains the supplier's choice.
2025
2025-01-01In effect
VAT returns must be filed through the eMWST portal
The Steuerverwaltung's eMWST portal became the mandatory channel for VAT returns. This is a filing-channel obligation and not a digital reporting requirement: periodic return data is submitted, and no invoice-level or transaction-level detail reaches the authority.
02
File format & data specification
EN 16931 is the standard, because that is what the directive requires an authority to accept. There is no national CIUS in effect and no national extension. There is also no platform: the European Commission's own country page records that invoices above EU thresholds are sent to the contracting authority by email, in XML or PDF. Liechtenstein has no Peppol Authority, and neither does Switzerland — a business may use Peppol commercially, but there is no domestic governance or infrastructure behind it.
Format & standard
StandardEN 16931, as the directive requires. No national CIUS is in effect; the Commission notes a draft addressing VAT requirements.
TransmissionBy e-mail to the contracting authority, in XML or PDF. There is no national e-invoicing platform and none is planned.
PeppolNo Peppol Authority in Liechtenstein, and none in Switzerland. A supplier using Peppol does so commercially, not to comply.
Identifiers & registration
Taxpayer identifierThe Liechtenstein VAT number, issued by the national tax administration — not a Swiss one, despite the shared VAT statute.
Supplier registrationNone. There is no register to join and no accreditation to obtain before invoicing a contracting authority.
Where competence sitsCompetence follows seat, not turnover: a Liechtenstein-seated business files with Liechtenstein.
Mandatory content
Invoice particularsThe Swiss VAT Act's content requirements apply in substance under the treaty of 28 October 1994, administered nationally.
For the B2G channelEN 16931's semantic model where a structured invoice is sent. Nothing additional is imposed nationally.
ThresholdThe receive obligation is expressed as applying above EU procurement thresholds.
Archiving
Ten yearsFrom the end of the financial year of the last entries, under PGR Art. 1059 and separately under the VAT Act.
Twenty yearsFor records concerning immovable property.
Electronic retentionPermitted. Records must not be alterable undetectably and must remain readable at any time.
SignaturesNamed in the ordinance as one example of assuring integrity, alongside others. Not a requirement.
03
Scope & transmission
The scope question here is unusually clean, because the obligation is on the buyer rather than the seller. Contracting authorities must be able to receive and process a compliant electronic invoice for procurement above EU thresholds. Suppliers to those authorities may invoice electronically and are not required to. No business, of any size, in any sector, is obliged to issue an electronic invoice to anyone.
Two regimes, and which fact comes from which
Swiss VAT law, by treatyThe treaty of 28 October 1994 makes Swiss VAT substance applicable, but through Liechtenstein's own VAT Act (LGBl 2009 Nr. 330). B2B, B2C, e-reporting and the signature position all sit here.
Liechtenstein's own administrationCompetence follows seat, not turnover: a Liechtenstein-seated business files with the Liechtenstein Steuerverwaltung and never with the Swiss FTA. Import VAT is the exception and is administered on the Swiss side.
The EEA Agreement, for procurementAnnex XVI covers public procurement, which is how Directive 2014/55/EU reached a non-EU state. The B2G answer is genuinely Liechtenstein's own.
What this asymmetry predictsIndirect taxation is expressly outside the EEA Agreement. ViDA and any future EU B2B or digital reporting requirement will not propagate here. European procurement instruments will.
⚠️ "No B2G mandate" is quoted out of context
What the Commission saysIts country page states that Liechtenstein does not have a B2G e-invoicing mandate — meaning no duty on suppliers to SEND — and asserts the authorities' duty to RECEIVE on the same page.
How it gets re-quotedThe first half circulates on vendor trackers as though Liechtenstein had no B2G obligation at all. It has one; it simply falls on the buyer.
Why the difference matters to youIf you supply the Liechtenstein administration you may invoice electronically and be confident it can be received and processed. That assurance is the whole point of the directive, and it is what a bare "no mandate" would hide.
04
Getting compliant
There is no compliance project here, and that is the finding rather than an omission. What is worth doing is confirming which administration you deal with, getting onto the mandatory filing portal, and knowing which of your obligations would move if Europe legislated again.
Confirm which administration you deal with
Competence follows your seat, not your turnover. A Liechtenstein-seated business files domestic VAT with the Liechtenstein Steuerverwaltung; a business seated elsewhere in the joint territory files with the Swiss FTA. Import VAT is administered on the Swiss side either way.
Get onto eMWST if you have not
Filing VAT returns through the portal has been mandatory since January 2025. This is the one Liechtenstein obligation with a recent date on it, and it is administrative rather than substantive — no invoice data is transmitted.
If you supply the administration, consider invoicing electronically anyway
You are not required to, but the authority is required to accept and process a compliant invoice. That assurance exists in law and most suppliers never use it.
Know which of your obligations would move, and which would not
A future EU B2B or digital reporting mandate cannot reach Liechtenstein: indirect taxation is outside the EEA Agreement. A future European procurement instrument can and would. If you are planning across markets, that is the line to plan against.
05
Penalties & enforcement
There are no e-invoicing penalties, because there is no e-invoicing obligation on a business to breach. What does carry consequences is record-keeping: the retention rules below sit in Liechtenstein's own company and tax law and apply whatever form your invoices take.
What is actually enforced
No e-invoicing penaltyThere is none, because no supplier has a duty to issue. The obligation runs the other way, onto the contracting authority.
What does bind youThe bookkeeping and retention duties of the PGR and the VAT Act, enforced by the national tax administration.
Your practical remedyAn authority that refuses a compliant EN 16931 invoice is the one in breach of the procurement act, not you.
The EU floor that reaches Liechtenstein, and the one that does not
Procurement law doesDirective 2014/55/EU reached a non-EU state through Annex XVI of the EEA Agreement, which covers public procurement.
Indirect taxation does notIt is expressly outside the EEA Agreement, so ViDA and any future EU B2B or digital-reporting rule do not bind Liechtenstein.
What that predictsLiechtenstein will keep tracking EU procurement rules and will not automatically follow EU VAT ones. Plan the two separately.
🔍 What we could not confirm
The article imposing the receive dutyThe Commission attributes it to Article 44a of the procurement act; Article 44a is about consulting trade associations, and the Act truncates on retrieval. What is confirmed is Article 1a, which lists Directive 2014/55/EU as implemented, and Article 7, which carries its definitions.
The transposition date in national lawA consolidated version of the procurement act commences on 27 November 2018, the EEA compliance date. The coincidence is compelling and the amending text could not be read.
The 1994 treaty's own textIts name, date and reference are confirmed from the VAT Act and the 2012 supplementing agreement. The treaty text itself is served by a JavaScript-only site and could not be retrieved.
The national CIUSThe Commission says none is applied but that a draft addressing VAT requirements exists. Author, status and timeline unknown.
