E-Invoicing Mandates by Country: Timeline and Official Sources

E-invoicing mandates by country differ in three ways: the model (clearance by the tax authority, exchange between the parties, or reporting), who is in scope, and when each phase starts. In Europe, Italy has required B2B e-invoices since 2019, and Belgium, Croatia, Poland and Greece brought theirs in during 2026. France's phase-in started on 1 September 2026, and Germany's issuing duty starts on 1 January 2027 for businesses with prior-year turnover above EUR 800,000. The EU's ViDA package requires e-invoicing for intra-EU B2B supplies from 1 July 2030. Clearance systems have run for years across Latin America and in Turkey, India, Saudi Arabia and Egypt. The UAE follows from 1 January 2027, and the UK has announced 1 April 2029.

Of the 85 jurisdictions tabled on this page, 39 have B2B e-invoicing or clearance in force for at least some businesses. Each row links the official pages it rests on (tax authority, finance ministry, gazette, parliament, state news agency or the European Commission) in its Source column, with the date each page gives where it gives one. Status is named exactly: in force, enacted, announced, proposed, or postponed from one date to another. Phases are written out by who and from when, never flattened into one "mandatory since" date.

Last checked: 30 October 2026. Rows whose dates fall near that day are worded by date ("from 2 November 2026") so that each reads correctly whichever side of the date you meet it. Before acting on a row, check the authority's page it links: mandate dates move, and that page moves first.

Where Countries Stand: This Page's Count and the Dated Changes to the End of 2027

The tables below give a sourced row to 85 jurisdictions. Seven more were checked and showed no mandate on the authority's site, and 20 could not be confirmed on an official page; both groups are listed after the tables. That makes 112 in all.

Counted from this page's own tables, by the strongest obligation each jurisdiction places on invoices between businesses:

• 39 have B2B e-invoicing or clearance in force for at least some businesses. A country counts once the obligation applies to at least one group, so Singapore, whose rule so far covers only new voluntary GST registrants, is here, and so is Nigeria, whose law already binds anyone making a taxable supply though no phase dates are published.
• 10 have enacted a mandate whose issuing duty has not yet started for anyone: Bosnia and Herzegovina (the Federation), Germany (where receiving e-invoices has been compulsory since 1 January 2025), Latvia, Norway, Slovakia, Slovenia, Spain, Oman, the UAE and the Philippines.
• 6 have a mandate announced, targeted or planned by government that is not yet law: Ireland, Lithuania, the Netherlands, the United Kingdom, Sri Lanka and Botswana.
• 5 have one proposed only in a consultation, draft law or bill: Bulgaria, Luxembourg, Moldova (public contracts only), Qatar and South Africa.
• 4 require real-time reporting or fiscalisation of invoices but no e-invoice: Hungary, Montenegro, Rwanda and Zimbabwe.
• 15 require e-invoicing only for the public sector, or give buyers a right to ask for e-invoices, with no B2B mandate: Austria, Cyprus, the Czech Republic, Denmark, Estonia, Finland, Iceland, Liechtenstein, Malta, Portugal, Sweden, Switzerland, the United States, Australia and New Zealand.
• 6 have no mandate, with e-invoices voluntary or promoted: Canada, North Macedonia, Thailand, China, Japan and Taiwan.

These are counts of this page's table, with the definitions above. The larger round numbers that circulate for "countries with e-invoicing mandates" are discussed under the field's figures below.

Dated changes, November 2026 to December 2027

Each item is sourced in its country's row.

• 1 November 2026: Argentina's RG 5893/2026 requires original electronic vouchers from VAT-registered, VAT-exempt and Monotributo taxpayers (non-VAT subjects from 1 March 2027). Brazil's Simples Nacional micro and small businesses issue service invoices through the national NFS-e.
• 2 November 2026: Greece's second period starts: all remaining businesses issue only e-invoices, with parallel issuing allowed to 31 January 2027 after a declaration.
• Six months from 15 May 2026: the Dominican Republic's automatic extension for micro, small, medium and unclassified taxpayers runs out.
• 1 December 2026: Argentina brings loans and cardholder statements into electronic invoicing. Brazil's wave for platform services, property, metropolitan and air tickets and non-ICMS taxpayers starts.
• 31 December 2026: covered taxpayers in the Philippines must be issuing e-invoices. Poland's relief for invoices up to PLN 10,000 gross a month ends, so KSeF covers every business from 1 January 2027.
• 1 January 2027: Germany's issuing duty starts for businesses with prior-year turnover above EUR 800,000. Slovakia's B2B and B2G mandate, Norway's issuing duty and Croatia's issuing duty for non-VAT taxpayers start. UAE businesses with revenue of AED 50 million or more implement e-invoicing. Spain's VeriFactu deadline for corporate income tax payers falls (a deferral to October 2028 has been announced, not enacted). New Zealand's larger agencies require eInvoices from large suppliers. Brazil's Simples Nacional reform documents start, Turkey's e-Arşiv obligation reaches simple-method taxpayers, and Peru's RS 48-2026 takes effect.
• 31 January 2027: Greece's parallel issuing for the second period ends.
• 1 February 2027: Saudi Arabia's Wave 25 (revenue above SAR 187,500) starts integrating with ZATCA.
• 1 March 2027: Argentina's last RG 5866/2026 stage (coinsurance, merchant settlements) and RG 5893/2026's deadline for non-VAT subjects.
• 31 March 2027: UAE businesses below AED 50 million, and government entities, appoint an Accredited Service Provider.
• 1 April 2027: Oman starts with businesses whose supplies exceed OMR 5,000,000. Peru designates its new electronic issuers under RS 48-2026.
• 1 July 2027: UAE businesses below AED 50 million implement. Spain's VeriFactu deadline for all other obliged taxpayers falls (the same announced deferral applies).
• 1 September 2027: France's SMEs and micro-enterprises start issuing e-invoices.
• 1 October 2027: Oman's remaining businesses and UAE government entities.
• 6 October 2027: Spain's B2B e-invoicing starts for businesses with a volumen de operaciones above EUR 8 million.
• 31 December 2027: Germany's transitional rules end for small businesses and EDI invoices, and Malaysia's relaxation period for its final phase ends.

Several items around this window are not law: the Dutch bill due in Parliament before summer 2027, Poland's draft deferring KSeF penalties to 31 December 2027, Bulgaria's consultation aiming at adoption by the end of 2026, and Spain's announced VeriFactu deferral.

How to Read the Tables: Models and Status Words

The Model column says how the invoice travels and who sees it. Five models cover almost every row:

• Clearance. The tax authority, or a provider it accredits, validates the invoice before it has legal effect. Italy's Sistema di Interscambio (SdI), Poland's KSeF, Mexico's CFDI stamped by an authorised provider (PAC) and Saudi Arabia's integration phase all work this way, as do most Latin American systems.
• Decentralised exchange. The supplier and buyer exchange structured e-invoices through providers, and the authority does not stand in the flow. Peppol is the common network: in its four-corner model each party has an access point, and in the five-corner variant a copy of the invoice data also goes to the tax authority, as in Singapore, the UAE and Oman.
• Reporting. Invoice data goes to the authority in real time or near it, but the law does not require the invoice itself to be electronic. Hungary's Online Számla is the clearest case.
• Fiscalisation. Invoices or receipts are recorded through certified devices or software, and their data reaches the authority as they are issued. It began in retail and now often extends to every sale.
• Public sector only (B2G). Public bodies must receive e-invoices, or their suppliers must send them, with no rule for invoices between businesses.

Almost none of these regimes accepts a PDF sent by email as an e-invoice. The standard most European mandates name is EN 16931, a structured format a buyer's system can read without retyping. Our guide to what e-invoicing is and how the formats differ covers the basics behind these terms.

The Status column uses five words, and the instrument behind each is named in the row where it is known:

• In force: the obligation applies today to at least the group named.
• Enacted: a law or regulation sets the date, which has not yet arrived.
• Announced: the government has published dates as its policy (by decision, roadmap or timeline), or announced a plan, but no law yet carries them.
• Proposed: the plan, and any dates, appear only in a consultation, draft law or bill.
• Postponed: an enacted date has been moved, written as old date to new.

ViDA: What the EU's VAT in the Digital Age Package Requires, and What It Does Not

The VAT in the Digital Age package was adopted on 11 March 2025 (Commission, adoption of the ViDA package). It has three legal acts: Council Directive (EU) 2025/516, which amends the VAT Directive 2006/112/EC; Council Regulation (EU) 2025/517 on administrative cooperation; and Council Implementing Regulation (EU) 2025/518. The implementing regulation applies from 1 July 2028, except Article 1 points (2) to (7), which applied from its entry into force (Implementing Regulation 2025/518). The e-invoicing rules arrive in three steps.

Since 14 April 2025, a Member State may require businesses established on its territory to issue domestic e-invoices without the recipient's acceptance (Directive 2025/516). Before ViDA, a country wanting a B2B mandate needed a derogation from the VAT Directive. That step is gone (Commission, VAT in the Digital Age).

From 1 July 2030, intra-Community B2B supplies move to e-invoicing with digital reporting:

• The invoice is a structured e-invoice that allows automated processing, with EN 16931 as the default standard, and no acceptance by the recipient is needed.
• Invoices for intra-Community supplies and for reverse-charged supplies must be issued no later than 10 days after the chargeable event (Directive 2025/516).
• The supplier reports the transaction, and the customer reports it no later than 5 days after receiving the invoice, so that the two reports can be matched across borders; Member States may opt out of the customer's report (Commission, ViDA).
• A central VAT information exchange system (central VIES) starts on the same date, under Regulation 2025/517, whose other articles apply from 1 July 2028, 1 July 2029 and 1 July 2032 (Regulation 2025/517).

By 1 January 2035, a Member State whose domestic real-time reporting system existed before 1 January 2024 must align it with the EU model (Article 6(5) of Directive 2025/516; Commission, ViDA).

What ViDA does not do matters as much for planning:

• It does not mandate domestic B2B e-invoicing in any Member State. Belgium, Croatia, Poland, Greece, France and Germany each have one under their own law and on their own dates, as the Europe table shows. A business that trades only domestically in a country without its own mandate is not caught by ViDA.
• It names no network. ViDA sets EN 16931 as the default format. The claim that Peppol becomes mandatory for intra-EU B2B trade is not in the texts; Peppol is one way to exchange EN 16931 invoices, and several countries have chosen it for their own domestic mandates.
• It does not oblige domestic reporting. Domestic digital reporting on the EU model remains optional for Member States, though several countries' own reforms already link their cross-border phase to 1 July 2030.

For e-invoicing in Europe, ViDA therefore sets a floor for cross-border trade from 2030, not a single EU-wide date. The national tables below carry the dates that apply first.

Europe: E-Invoicing Mandates Country by Country

E-invoicing in Europe now runs at several speeds. Since April 2025 a Member State has been free to impose domestic B2B e-invoicing without asking Brussels, and several have fixed dates from 2026 to 2028. Outside the EU, Serbia, Albania and Turkey have run central systems for years, and the UK and Norway have set their own dates.

The Americas: Clearance Across Latin America, No Mandate in the US or Canada

Latin America has run clearance longer than any other region: the authority, or a provider it authorises, validates each invoice before it has legal effect. Mexico, Chile, Ecuador, Peru and Costa Rica finished universal phase-ins years ago, and Uruguay did so in 2025. What changes now is scope (Argentina's remaining exceptions, Brazil's tax-reform documents) and format versions. North America has no domestic mandate.

Latin America and the Caribbean

North America

The Middle East: Clearance in Saudi Arabia and Egypt, Peppol Five-Corner in the UAE and Oman

The region splits by model. Saudi Arabia and Egypt clear invoices through the authority's own platform, Israel clears a number for each large invoice, and Jordan routes every sale through a national system. The UAE and Oman, both starting in 2027, chose a Peppol-based five-corner exchange through accredited providers instead.

Two countries' official texts disagree with each other, and the table does not reconcile them:

• Saudi Arabia. The gazette decision brings Wave 25 into integration "starting from" 1 February 2027, and so does ZATCA's Arabic news release. Its English release reads "by no later than" 1 February 2027, which turns a start date into a deadline.
• United Arab Emirates. Ministerial Decision 197 of 2026 excludes transactions between members of the same Tax Group from e-invoicing for 24 months from 1 January 2027. The Guidelines V2.0 describe the same relief as a grace period that keeps those transactions in scope. On penalties, the Guidelines cite Cabinet Decision 173 of 2026, while the ministry's eInvoicing page still lists Cabinet Decision 106 of 2025.

Asia-Pacific: From India's IRN to Singapore's InvoiceNow

Asia-Pacific holds the widest spread of models: clearance in India, Indonesia, Malaysia and Vietnam, Peppol exchange in Singapore, Australia and New Zealand, and no issuance mandate in Japan, Thailand or Taiwan. Most of the mandates phase in by turnover, so the threshold in a row decides whether a business is in.

South Asia

South-East Asia

East Asia

Australia and New Zealand

Africa: Mandates in Force in Kenya, Uganda and Ghana, Proposed in South Africa

African systems range from certified billing machines to a Peppol-based exchange in Nigeria. Several mandates switch businesses on by the authority's selection or notice rather than by a published calendar, so a row may state the obligation without a date for every business.

Jurisdictions This Page Could Not Confirm

Twenty-seven jurisdictions have no row above, for one of two reasons.

No e-invoicing mandate found on the authority's site, checked October 2026: Bahrain, Kuwait, Bangladesh, Barbados, Haiti, Jamaica, and Trinidad and Tobago. A home page is not proof that nothing exists, so these are not counted as "no mandate" in the summary.

Not confirmed on an official page. The authority's site could not be reached, or no page bearing on e-invoicing could be read, so this page gives no status or date:

• Europe: Kosovo, Ukraine
• Central Asia: Azerbaijan, Kazakhstan, Uzbekistan
• The Americas: Bolivia, Guatemala, Honduras, Nicaragua, Paraguay, Puerto Rico, Venezuela
• Africa: Benin, Cameroon, Côte d'Ivoire, Ethiopia, Morocco, Senegal, Tanzania, Zambia

Trackers and the press print dates for most of these, and several may well be accurate. They stay off this page until the authority's own page confirms them. For the invoicing rules a business meets in four of them today, see Kosovo's fiscalisation requirements, Ukraine's tax invoice registration and blocking, Honduras invoice requirements and Puerto Rico's IVU invoice requirements.

The Field's Figures: Adoption, the VAT Gap, How Many Countries and What an E-Invoice Saves

Each figure below sits beside its source, with what it measures and the period it covers.

Adoption

In 2023, 38.68% of EU enterprises with 10 or more persons employed sent e-invoices suitable for automated processing, up from 24.79% in 2018 (Eurostat, isoc_eb_ics; view the table). The spread between member states is wide: 97.46% in Italy and 93.21% in Finland, against 14.81% in Poland and 15.79% in Bulgaria. Italy's figure reflects a clearance mandate in place since 2019. Poland's predates the KSeF mandate of 2026.

By company size, 37% of small, 44% of medium-sized and 59.8% of large EU companies sent e-invoices in 2023, against 22.6%, 33% and 49.2% in 2018. The same report, the EU Payment Observatory's third thematic report, prepared by CEPS and EY for the Commission, finds that the countries with the lowest adoption generally lack an e-invoicing mandate (EU Payment Observatory, e-invoicing and late payments).

National surveys show the same split between structured and unstructured invoices. In Ireland in 2023, 29% of enterprises used e-invoices suitable for automated processing, 60% used e-invoices that were not (PDFs and images), and 44% used paper (CSO, Information Society Statistics 2023). The categories overlap, since one enterprise uses several.

The United States has no current official adoption statistic. The Federal Reserve Bank of Minneapolis, relaying analyst estimates in 2016, put US invoice volume at as many as 25 billion a year with only about 25 percent exchanged electronically: a share of invoices, not of businesses (Minneapolis Fed, U.S. Adoption of Electronic Invoicing). The same paper cites PayStream Advisors' estimate of $4 to $8 saved per paper invoice converted. The Federal Reserve Bank of Cleveland reported in September 2026 that nearly 90 percent of US businesses still use checks for at least some B2B payments, and gives no e-invoicing share (Cleveland Fed, B2B payments research brief).

Why governments mandate it

The EU VAT compliance gap was EUR 128 billion in 2023, 9.5% of VAT total tax liability, 1.6 percentage points higher than in 2022 and down from 11.1% in 2019 (European Commission, VAT gap). It was highest in Romania (30%) and Malta (24.2%) and lowest in Austria (1%) and Finland (3%) (Commission news release, 11 December 2025). The Commission says ViDA will help close it by enforcing e-invoicing, real-time automated reporting and cross-border data matching.

When it proposed ViDA in December 2022, the Commission estimated the package would bring up to EUR 18 billion more VAT revenue a year, that e-invoicing would cut VAT fraud by up to EUR 11 billion a year, and that traders' costs would fall by over EUR 4.1 billion a year over ten years (Commission press release IP/22/7514). The proposal itself put net benefits at EUR 172 billion to EUR 214 billion over 2023 to 2032, including EUR 51 billion in savings, against an implementation cost of EUR 13.5 billion. It put missing-trader intra-Community fraud at EUR 40 billion to EUR 60 billion, within a 2020 VAT gap of EUR 93 billion (COM(2022) 701 final).

How many countries have e-invoicing mandates?

Only the OECD publishes figures close to an official count, and its two figures measure different things. In a 2021 survey of 71 tax administrations, 46% said they collect e-invoices or e-invoice data on a systematic basis; of those that did not, 70% cited the lack of an e-invoicing policy embedded in law (OECD's 2022 report on tax administrations and e-invoicing). In fiscal year 2023, 46.6% of the 58 administrations covered by Tax Administration 2025 required certain categories of taxpayers to use an electronic invoice mechanism that transfers data to the administration (OECD, Tax Administration 2025, Table 6.1). The two surveys cover different administrations and ask different questions, so the pair is not a trend.

The round numbers that vendor guides commonly print ("more than 80 countries", "60+", "90+") come with no method and no list of countries. They differ because they count different things: public-sector rules, B2B mandates, reporting regimes, announcements. This page's own count, set out above, is 39 jurisdictions with B2B e-invoicing or clearance in force for at least some businesses, out of the 85 it gives a sourced row.

Peppol

OpenPeppol's list of Peppol Authorities names authorities for 26 countries or territories (our count of the list; the page states no total). Several are now tax administrations rather than procurement agencies: Australia's ATO, France's DGFiP, Greece's GSIS, the Oman Tax Authority, the Nigeria Revenue Service, Slovakia's Financial Directorate and the UAE Ministry of Finance (OpenPeppol, Peppol Authorities). Peppol began as a public-procurement network and now carries tax mandates.

OpenPeppol's country profiles add detail. In Norway, about 50% of the 140 million B2B and B2G invoices sent each year use the EHF/Peppol BIS format (Peppol country profile: Norway). Poland's KSeF operates outside Peppol, though it can accept invoices issued in the Peppol BIS format (Peppol country profile: Poland). In Malaysia, submitting through a Peppol provider is one of the options the Inland Revenue Board recognises, and Peppol e-invoicing for business digitalisation is voluntary (Peppol country profile: Malaysia). In Australia, e-invoicing is not mandatory for businesses, though some mandates apply to government agencies (Peppol country profile: Australia). The UK announced on 23 June 2026 that Peppol will be its core interoperability network, ahead of its 2029 mandate (HM Government, Tax update 2026 summary).

Volumes: analyst estimates

The analyst firm Billentis, whose reports are sponsored by e-invoicing vendors, estimates that around 300 billion B2B invoices are issued worldwide each year, of which about 87 billion (29%) are electronic. Its electronic share runs from 78% in Latin America and 64% in Europe to 36% in North America and 17% in Asia (Billentis, Riding the Tornado, June 2026). These are estimates, and they measure a share of invoices, so Europe's 64% does not contradict Eurostat's 38.68%, which is a share of enterprises.

What an e-invoice saves

The European Commission estimated the benefit of automating invoicing at around EUR 5.28 per e-invoice issued and EUR 8.4 per e-invoice received, at a labour cost of EUR 46 an hour. The same report records that as of July 2023, 17 of the 27 Member States required suppliers to issue e-invoices to the public sector, fully in 13 and partially in four (Commission report on Directive 2014/55/EU, COM(2024) 72).

A Hasselt University study of Belgian firms costed each format in 2014. Receiving a B2B invoice cost EUR 8.04 on paper, EUR 7.68 as an emailed PDF and EUR 2.27 as a structured e-invoice. Sending one cost EUR 4.44, EUR 2.02 and EUR 1.20. Because emailed invoices cost the receiver almost as much as paper, only 27.5% of the potential savings (EUR 0.93 billion) were being reached (Poel, Marneffe and Vanlaer, Hasselt University). That gap, between a PDF someone has to read and a structured file a system can, is why mandates specify structured formats rather than electronic delivery alone.

Where Trackers Commonly Go Wrong

Most conflicting dates come from a handful of repeated errors. Each official position below is sourced in its country's row.

• A pilot printed as a nationwide mandate. China's digital invoices began as a three-region pilot in December 2021 and went nationwide on 1 December 2024, and paper still has equal legal effect.
• A first phase printed as the mandate. Saudi Arabia's Phase 1 (December 2021) only required generating e-invoices; integration has come in waves since 2023.
• A narrow phase printed as the whole. Singapore's InvoiceNow requirement so far covers new voluntary GST registrants; everyone else follows from 2028 to 2031, by phases not yet in law.
• A superseded threshold. Malaysia's exemption is below RM3 million from 1 September 2026, not RM1 million.
• Systems in force described as "planning or piloting". Kenya and Egypt have run mandatory systems for years, and Nigeria's obligation is in force by law.
• Announcements printed as law, and law printed as announcement. Belgium's 2028 e-reporting and Ireland's 2028 and 2029 phases are not yet law. Spain's B2B mandate is: Royal Decree 238/2026 and Order HAC/1028/2026 set its dates.
• Dates already moved. Greece's two periods run from 2 March 2026 and from 2 November 2026, later than the dates first set in 2025. The Dominican Republic's smaller taxpayers were given six months more from 15 May 2026.
• Dates with no official basis. "Mandatory for B2B as of 2018" for Thailand, "mandatory since January 2021" for Taiwan and "July 2025" for Bahrain match nothing on the authorities' pages.
• A proposal dated as a mandate. South Africa is often given 2028, but SARS's 2026 consultation paper expects implementation to begin during 2030.
• An old figure presented as current. The EUR 93 billion EU VAT gap is the 2020 figure; the latest is EUR 128 billion for 2023.

How This Page Is Kept

This page was last checked on 30 October 2026. Rows whose status was changing around that date (Greece, Spain, the UAE, Argentina, the Dominican Republic, Oman, Ireland, the UK and others) were re-read on the authority's own page on 29 and 30 October 2026.

Mandate dates move: the rows for Latvia, Pakistan, the UAE, the Dominican Republic, Peru and Brazil already record a postponement or extension, and Spain's records an announced one. The authority's page linked in each row is the one to check before acting, and the instrument named in the row (a gazette decision, a resolution, a ministerial decision) is the one a tax adviser will ask for.

The invoices these mandates produce also have to be kept, for periods that vary as much as the mandates do: see invoice retention periods by country.
