Country deep dive
Latvia's B2G e-invoicing requirement began with EU-directive transposition: central government bodies from 18 April 2019, all contracting authorities from 18 April 2020. Domestic law then extended this: from 1 January 2025, all Latvian-registered companies must issue structured e-invoices to government/budget entities. A originally planned 1 January 2026 B2B mandate was postponed by the Saeima on 5 June 2025 to 1 January 2028, with two intermediate steps in between: mandatory e-invoice data reporting to VID for B2G/G2G/G2B from 1 January 2026, and a voluntary B2B e-invoicing/reporting phase open since 30 March 2026.
From 18 April 2019, Latvia's direct administration institutions (central government bodies) became required to receive structured e-invoices, under Cabinet Regulation No. 154, transposing EU Directive 2014/55/EU.
From 18 April 2020, the B2G e-invoice receipt requirement extended from central government bodies to all other Latvian contracting authorities, completing the initial EU-directive rollout ahead of the later domestic e-invoicing law.
From 1 January 2025, amendments to Latvia's Accounting Law (Gramatvedibas likums) require all Latvian-registered companies to issue structured e-invoices -- formatted to EN 16931 (LVS EN 16931-1:2017) -- to budget and government (B2G/G2G) entities, exchanged via the free national eAddress (e-adrese) platform, a certified Peppol Access Point, or another VID-integrated channel.
On 5 June 2025, the Saeima (Latvian Parliament) adopted amendments postponing the mandatory B2B e-invoicing/e-reporting go-live from the originally planned 1 January 2026 to 1 January 2028 -- rejecting a rival proposal for an intermediate 2027 date in favour of a longer runway plus an interim voluntary phase. The stated rationale was to give taxpayers, especially small businesses, more preparation time, and to allow the eAddress platform to be upgraded first.
From 1 January 2026, Cabinet Regulation No. 749 (adopted 9 December 2025) makes reporting structured e-invoice data to the State Revenue Service (VID) mandatory for B2G/G2G/G2B transactions, via eAddress, a certified Peppol Access Point with a VID API integration, or manual upload through VID's Electronic Declaration System (EDS). Note: this regulation's full text could not be independently verified via likumi.lv in this research session -- confirmed only via a secondary summary.
From 30 March 2026, Latvian companies can voluntarily begin issuing structured B2B e-invoices and reporting the data to VID via eAddress, ahead of the mandatory 1 January 2028 date -- an interim step built into the 5 June 2025 postponement to let the platform and businesses prepare gradually rather than face a hard cutover.
From 1 January 2028, all companies and taxable persons registered in Latvia must issue and report structured, EN 16931-compliant e-invoices for domestic B2B transactions -- via eAddress, a certified Peppol Access Point, or direct bilateral exchange paired with separate VID data-reporting within 5 working days. Cross-border B2B invoices are not covered by this domestic mandate. No dedicated e-invoicing penalty schedule has been published as of this research; the practical consequence today for non-compliant B2G invoices is rejection by the receiving government entity, not a monetary fine.
The semantic standard is EN 16931 (implemented in Latvia as LVS EN 16931-1:2017 and LVS CEN/TS 16931-2:2017), expressed in UBL 2.1 or Peppol BIS Billing 3.0 XML. For B2G, Peppol Access Points are standard practice. For the future B2B mandate, Latvia does not designate a single mandatory transmission network: structured e-invoices can move via the free national eAddress (e-adrese) platform, a certified Peppol Access Point integrated with a VID API, or direct bilateral exchange (EDI, email, software-to-software) -- but direct exchange carries a separate obligation to report the invoice data to VID within 5 working days. This makes Latvia's B2B model a decentralized e-reporting regime, not a pure "send everything over Peppol" mandate.
Latvia's upcoming B2B regime is best understood as a decentralized e-reporting model, not a pure Peppol mandate -- Peppol is one permitted transport, not the required one.
Cabinet Regulation No. 749 (adopted 9 Dec 2025, effective 1 Jan 2026) sets these procedures in detail -- its full text could not be independently verified via likumi.lv in this research session, so treat the specifics as a secondary summary pending direct confirmation.
The live B2G/G2G/G2B mandate covers all Latvian-registered companies supplying budget or government institutions. The future B2B mandate (from 1 January 2028) covers all companies and taxable persons registered in Latvia for domestic transactions only -- cross-border B2B invoices are not covered. No confirmed permanent small-business revenue/size exemption was found; the phased 2026-2028 timeline is explicitly framed as giving smaller businesses more preparation time, not a threshold-based carve-out. Confirmed exemptions include cash-register/fiscal-receipt transactions, National Health Service transactions, and certain national-security agencies (State Security Service, Police, Tax Police, and the Anti-Corruption Bureau/KNAB).
The European Commission's own Latvia eInvoicing country factsheet still shows a 1 January 2026 B2B date as of this research -- it has not been updated since the postponement. Treat the more recent, independently corroborated sources on this page (including a 22 July 2026 update) as authoritative over that factsheet for the B2B date.
If you supply Latvian government or budget entities, the live obligations (B2G e-invoicing since 2025, VID data reporting since 2026) apply now. For B2B trade within Latvia, there is no current mandate -- the work ahead is using the voluntary phase (open since 30 March 2026) to prepare a reporting channel well before the 1 January 2028 mandatory date, rather than waiting for a deadline that was already pushed back once.
Mandatory since 1 January 2025 -- confirm your invoices are EN 16931-compliant (UBL 2.1 or Peppol BIS Billing 3.0), not paper or plain PDF.
Mandatory since 1 January 2026 for B2G/G2G/G2B transactions -- via eAddress, a certified Peppol Access Point, or manual submission through VID's Electronic Declaration System (EDS).
Open since 30 March 2026 via eAddress -- using it now lets you test your reporting process well before the mandatory 1 January 2028 date.
It has not been updated since the 5 June 2025 postponement and still shows 1 January 2026 -- use the sources listed on this page instead.
There is currently no confirmed grace period beyond that date, and the deadline has already been pushed back once -- don't assume a further delay.
No dedicated e-invoicing penalty schedule has been published in Latvia as of this research. The practical consequence today for a non-compliant B2G invoice is rejection by the receiving government entity (blocking payment), not a fine. General Accounting Law penalties exist as a broader framework that would likely apply by analogy to bookkeeping/documentation failures, but no source ties a specific EUR figure directly to e-invoicing non-compliance.
