The penalties of article 57 of the Greek Code of Tax Procedure therefore apply:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Transactions subject to VAT:<\/strong> 50% of the VAT, with a minimum of \u20ac250 (single-entry books) or \u20ac500 (double-entry books).

From <strong>1 January 2027<\/strong>, the loading, transshipment and receipt procedures, as well as the transmission of quantity-check data, are activated for all businesses. From <strong>1 January 2028<\/strong>, uniform item coding based on the TARIC nomenclature follows. Any business that moves goods should plan the two transitions together.<\/p>\n\n\n\n<p><strong>For olive growers:<\/strong> the obligation to issue digital movement documents was also moved to 1\/1\/2027. The postponement applies provided that, on receiving the olives, the olive mill issues a quantity receipt note, and concerns those not in the first period.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">E-invoicing: the steps we recommend<\/h2>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Confirm whether you belong to the second period<\/strong> and whether you issue B2B or B2G invoices.<\/li>\n\n\n\n<li><strong>Choose your route:<\/strong> a provider if you have an ERP, POS or many invoices; timologio if you issue only a few.<\/li>\n\n\n\n<li><strong>If you go with a provider,<\/strong> sign a contract with a start date by 2\/11\/2026, grant the authorisation in Taxisnet and check that the declaration was filed by 12\/11.<\/li>\n\n\n\n<li><strong>If you go with timologio and want the adjustment period,<\/strong> file the declaration yourself by 12\/11\/2026.<\/li>\n\n\n\n<li><strong>Run test invoices<\/strong> and train whoever issues invoices, so that on 1\/2\/2027 nothing needs to change.<\/li>\n<\/ol>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"1024\" src=\"https:\/\/upgradesolutions.gr\/wp-content\/uploads\/2026\/10\/e-invoicing-checklist-turnover-up-to-1-million-1024x1024.jpg\" alt=\"E-invoicing checklist for businesses with turnover up to \u20ac1 million\" class=\"wp-image-1020\" srcset=\"https:\/\/upgradesolutions.gr\/wp-content\/uploads\/2026\/10\/e-invoicing-checklist-turnover-up-to-1-million-1024x1024.jpg 1024w, https:\/\/upgradesolutions.gr\/wp-content\/uploads\/2026\/10\/e-invoicing-checklist-turnover-up-to-1-million-300x300.jpg 300w, https:\/\/upgradesolutions.gr\/wp-content\/uploads\/2026\/10\/e-invoicing-checklist-turnover-up-to-1-million-150x150.jpg 150w, https:\/\/upgradesolutions.gr\/wp-content\/uploads\/2026\/10\/e-invoicing-checklist-turnover-up-to-1-million-768x768.jpg 768w, https:\/\/upgradesolutions.gr\/wp-content\/uploads\/2026\/10\/e-invoicing-checklist-turnover-up-to-1-million.jpg 1080w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Frequently asked questions<\/h2>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>I only have retail sales. Do I need to do anything?<\/summary>\n<p>No. Retail transactions with consumers are not affected. But if you issue even one invoice to a business after 2\/11\/2026, it must be electronic, so it is wise to have an issuing method ready.<\/p>\n<\/details>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>I already use timologio. Do I need a declaration?<\/summary>\n<p>No, if from 2\/11\/2026 you will issue your invoices exclusively from the application. A declaration is needed only if you want to continue in parallel with your old method until 31\/1\/2027.<\/p>\n<\/details>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Can I keep issuing from my ERP?<\/summary>\n<p>Yes, if the ERP connects to a certified e-invoicing provider: in that case you continue working normally from your software. What stops is the direct transmission of invoices from the ERP to myDATA <strong>without a provider<\/strong>. That is allowed only until 31\/1\/2027 and only if a timely declaration has been filed.<\/p>\n<\/details>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Are the tax incentives for early adoption still available?<\/summary>\n<p>For the second period, the deadline for the incentives (increased 100% deduction of the related expenses) was 3 August 2026 and has passed. The obligation, however, applies as normal.<\/p>\n<\/details>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>I don&#8217;t have time to sign with a provider. What do I do?<\/summary>\n<p>Start with timologio with a start date by 2\/11\/2026 and file a declaration by 12\/11 if you want the adjustment period. You can add a provider later, and it will then file its own declaration.<\/p>\n<\/details>\n\n\n\n<h2 class=\"wp-block-heading\">We help you with the transition<\/h2>\n\n\n\n<p>As part of our <a href=\"https:\/\/upgradesolutions.gr\/en\/tax-planning-and-bookkeeping\/\">Tax Planning and Bookkeeping<\/a> service, the Upgrade Solutions team checks whether the obligation applies to you, recommends the right solution, handles the declarations in myAADE and supports you with your first invoices. <a href=\"https:\/\/upgradesolutions.gr\/en\/contact-us\/\">Contact us<\/a> or email <a href=\"mailto:info@upgradesolutions.gr\">info@upgradesolutions.gr<\/a>.<\/p>\n\n\n\n<p><strong>Read also:<\/strong> <a href=\"https:\/\/upgradesolutions.gr\/en\/digital-delivery-note-phase-b-postponement\/\">Digital delivery note: the Phase B dates<\/a> \u00b7 <a href=\"https:\/\/upgradesolutions.gr\/en\/start-smart-guide-self-employed-greece\/\">Self-employed in Greece: a guide for those starting now<\/a><\/p>\n\n\n\n<p><em>Sources: AADE \u2013 announcement of new deadlines 30.09.2026 (decisions A.1197\/2026 and A.1198\/2026), decisions A.1128\/2025, A.1129\/2025, A.1112\/2025, circular E.2004\/2026.<\/em><\/p>\n\n\n\n<p><em>This article is for information purposes only and does not replace specialised professional advice.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>E-invoicing in Greece becomes mandatory from 2\/11\/2026 for turnover up to \u20ac1 million.
