Country deep dive
Azerbaijan's e-qaimə mandate began on 1 April 2017 under Cabinet Decision No. 89, implementing Tax Code Article 71-1, and extended to all remaining taxpayers on 1 January 2018. In 2020 the separate electronic VAT invoice was abolished and merged into the e-qaimə. Cabinet Decision No. 26 of 2021 is the current rulebook. New timing rules took effect on 1 January 2026.
Cabinet of Ministers Decision No. 89 of 14 March 2017 approved the rules on the form, application, accounting and use of the electronic invoice, implementing new Tax Code Article 71-1. From 1 April 2017, persons registered for VAT purposes and persons falling under Tax Code Article 218.1.2 -- trade and public-catering businesses whose taxable transactions exceeded AZN 200,000 in any month of a rolling 12-month period -- had to issue electronic invoices for goods delivered, works performed and services rendered in the course of business. This start date and scope are confirmed on the State Tax Service's own e-qaimə page.
From 1 January 2018 the second phase of the same Article 71-1 framework brought in all other taxpayers, beyond the VAT-registered and Article 218.1.2 populations covered from April 2017. From this point Azerbaijan's mandate covers essentially the whole B2B commercial-supply population, with no revenue threshold on the e-invoicing obligation itself. The phasing is set out in the State Tax Service's own e-qaimə presentation. Persons who are not registered as taxpayers cannot issue electronic invoices at all.
From 1 January 2020 the electronic tax invoice (elektron vergi hesab-fakturası, e-VHF) was withdrawn and merged into the e-qaimə, which became the primary accounting document for all business transactions. VAT payers now use the e-qaimə itself as the document for calculating and offsetting input VAT -- previously it only evidenced the movement of goods. From the same date an issuer can no longer unilaterally cancel an invoice without the recipient's consent, and nine distinct invoice types were introduced. Worth stating plainly, because it is often described wrongly: this was not a paper-to-digital step. Azerbaijan's predecessor document had already been electronic since roughly 2008; 2020 merged two electronic systems into one.
From 1 January 2024 an electronic invoice must be issued on the day an advance payment is received, and the later delivery invoice must cross-reference that advance invoice by series and number. The obligation is notably not limited to VAT payers -- simplified-tax, non-VAT and profit-tax payers are all caught. Unusually, late submission of an advance e-invoice specifically does not attract a financial sanction, unlike ordinary e-invoices. Secondary Azerbaijani tax portals cite this provision as Article 71-1.5.12 while the State Tax Service's own 2026 FAQ cites the advance rule as Article 71-1.1.5; that numbering discrepancy could not be reconciled against a consolidated Tax Code text and is flagged rather than resolved here.
A law of 9 December 2025, applied by Presidential Decree No. 563 of 29 December 2025, inserted Tax Code Articles 71-1.1.3-1 and 71-1.1.3-2 with effect from 1 January 2026. The general five-day deadline for service invoices no longer applies to two categories. International transport services must be invoiced by the time the transport begins. Regularly and continuously supplied services -- security, cleaning, utilities, subscriptions -- must be invoiced for each calendar month at the point that month's service provision begins, even where the contract provides for quarterly or annual billing. The stated rationale is to stop taxpayers using the five-day window to shift transactions between reporting periods.
A compliant e-qaimə is an XML document drawn up in Azerbaijani, signed with an enhanced electronic signature, transmitted to the registered recipient through the State Tax Service portal and recorded in AVİS, the Automated Tax Information System. The State Tax Service publishes the file-format specification, sample templates and a goods, works and services classification file. Signing uses ASAN İMZA, e-İmza or SİMA Token, producing .adoc or .edoc containers.
The absence of EN 16931 and Peppol alignment is asserted by one secondary source and corroborated by silence elsewhere; no primary source addresses it either way.
Azerbaijan offers two modes, and the naming misleads people into thinking one of them lets you issue invoices outside the state system. It does not. In online mode you authenticate to the İnternet Vergi İdarəsi portal with an enhanced electronic signature and compose and send in real time. In offline mode you download eFP — Elektron Faktura hazırlama Proqramı — compose and package invoices with no internet connection, sign the package, and then upload it to the portal, at which point the State Tax Service assigns the series and number and emails confirmation. eFP is a preparation tool, not an issuance channel. There is no legally valid e-qaimə that never touches the State Tax Service, because the invoice's identity — its series and number — is state-issued rather than taxpayer-issued.
The mandate covers essentially the whole B2B commercial-supply population, with no revenue threshold on the obligation itself since the 2018 phase. B2C is out of scope as a rule — retail runs on new-generation cash registers instead — though a consumer may request an e-invoice in a retail or catering transaction. Persons not registered as taxpayers cannot issue electronic invoices at all, and non-residents do not issue Azerbaijani e-invoices.
B2G scope is inferred: it is asserted by two secondary sources and nowhere carved out, but no primary source explicitly names it.
Anyone researching Azerbaijan will hit a naming problem, so it is worth stating openly. One compliance source calls this a post-audit reporting model and explicitly not pre-clearance. A second calls it "post-audit clearance", which is internally contradictory. A third calls it a clearance model. All three describe the same mechanism. This page does not adopt any of those labels, because clearance overstates what happens and post-audit understates it. What is actually true, from primary sources: the invoice cannot exist outside the state system, its identity is state-issued, it is recorded in AVİS at issuance, and the system validates the counterparty tax ID and computes VAT automatically — but no tax officer or rules engine approves the substance of the invoice as a condition of its validity, and a passive counterparty auto-approves it after five days. That is registration-at-issuance, and describing it in a sentence serves a reader better than forcing it into a one-word category. One further caution: a 2025 industry article claims Azerbaijan mandated e-invoicing in 2010 under Tax Code Article 2. That is wrong — Article 2 concerns the basis of tax legislation, and the operative provision is Article 71-1, inserted for 1 April 2017. It is named here so a future reader does not reintroduce it from a search result.
An e-qaimə moves through this sequence in both online and offline modes:
The State Tax Service is inside the transaction in real time — but it numbers and records the invoice rather than approving it, and the decisive validation is the buyer's, or their silence.
If you supply goods, works or services in Azerbaijan as a registered taxpayer, you are already in scope and have been since 2018. The live work is the 1 January 2026 timing change, which is genuinely disruptive for anyone billing continuous services on a quarterly or annual cycle, and which most international compliance summaries have not yet picked up.
This is the most urgent item on the page. Since 1 January 2026, regularly and continuously supplied services — security, cleaning, utilities, subscriptions, and most SaaS — must be invoiced monthly, at the start of each month's service, even where your contract bills quarterly or annually. If your ERP is still following a blanket five-day service rule, it is following a rule that no longer applies.
International transport services must now be invoiced by the time the transport begins, not within five days of it. For freight and logistics operators this reverses the usual order of operations and needs a process change, not just a date field.
You need ASAN İMZA, an e-İmza certificate or a SİMA Token, plus access to the İnternet Vergi İdarəsi portal. If you plan to prepare invoices in bulk offline, install eFP as well — but remember it prepares rather than issues.
Article 58.8.2 penalises the buyer for holding goods without the required invoices, at the same escalating 10/20/40% rates. Chase suppliers who have not issued, and use the five-day confirmation window actively — silence counts as confirmation, so an unreviewed invoice becomes an accepted one.
New Article 155.1-1 counts cashless point-of-sale receipts at half value when testing the AZN 200,000 registration threshold, so a retail or services business can now run roughly AZN 400,000 of card turnover before mandatory registration. If you were close to the line, you may no longer be.
Azerbaijan publishes a real, quantified and escalating penalty schedule for e-invoicing failures, and it bites both sides of the transaction: the seller for not issuing, and the buyer for holding goods without the required invoices.
