The world is rapidly moving into a digital virtual space. In Ukrainian business and financial discourse, terms like SAF-T and iXBRL Taxonomy have become commonplace. Here is a brief overview of what they are, along with their main similarities and differences.<\/h3>\nTable of Contents<\/span><\/h3>\n\n- What is SAF-T?<\/a><\/li>\n

SAF-T (Standard Audit File for Tax)<\/span><\/h2>\n\nSAF-T<\/strong> (Standard Audit File for Tax) \u2014 is an international standard for the electronic exchange of accounting data in a unified XML<\/strong> format. It simplifies the submission of information to tax authorities and auditors during inspections. Ukraine is implementing this as SAF-T UA<\/strong> to automate electronic audits (e-audits), increase transparency, and reduce physical business inspections.<\/span><\/p>\n<\/div>\nThe standard was developed by the Organisation for Economic Co-operation and Development (OECD) in 2005. Typically, it is an XML file containing extracts from accounting and tax registers for a specific period. The goal of the standard is to simplify tax audits, automate control, and reduce compliance costs.<\/span><\/p>\nSAF-T (e-audit) is already officially in effect in Ukraine, but not yet for everyone. Its implementation follows a phased approach according to the Tax Code:<\/strong><\/span><\/p>\n\n- For large taxpayers: Since January 1, 2025, submitting the SAF-T UA file has been mandatory upon the tax authority’s request during an audit.<\/span><\/li>\n
- For all taxpayers: A gradual expansion to other business categories is expected throughout 2026\u20132027.<\/span><\/li>\n<\/ul>\n<\/blockquote>\n
The localized version, SAF-T UA, includes data on business operations, accounting, assets, tax liabilities, and other performance indicators.<\/span><\/p>\nBusiness Benefits: Fewer requests for paper copies; faster tax audits; and the ability to independently verify data using specialized software before submission.<\/span><\/p>\nRegulatory Framework for SAF-T UA
\n<\/strong><\/span><\/p>\n\n- Tax Code of Ukraine (TCU): Paragraph 85.2 of Article 85 obligates large taxpayers to provide electronic copies of accounting documents upon request.<\/span><\/li>\n
- Ministry of Finance: Decree \u2116 561 dated 15.09.2020 established the general principles of e-audit and the technical requirements for the SAF-T UA file.<\/span><\/li>\n
- State Tax Service (STS): Publishes and updates XSD schemas and technical descriptions.<\/span><\/li>\n<\/ul>\n<\/blockquote>\n
Instead of submitting the file only upon request during an audit, the draft law proposed making SAF-T UA a regular annual reporting form for large taxpayers and all VAT payers (starting from 2027). Taxpayers would have been required to submit the file within 60 calendar days after the end of the reporting year.<\/span><\/p>\nThe proposal included the introduction of a new article to the Tax Code (Art. 119-2), establishing penalties for non-submission or submission with errors:<\/strong><\/span><\/p>\n\n- 100 minimum wages for large taxpayers;<\/span><\/li>\n
- 10 minimum wages for other VAT payers.<\/span><\/li>\n<\/ul>\n<\/blockquote>\n
The draft law also requires enterprises submitting e-reporting to maintain accounting registers exclusively in electronic form.<\/span><\/p>\nAs of 2026, the electronic audit system has officially become fully operational. The State Tax Service (STS) now utilizes SAF-T UA as the primary data source for the automated verification of high-risk operations within large businesses. Although Draft Law No. 6255 was withdrawn from consideration, the STS of Ukraine launched a full-scale e-audit system on January 1, 2026. Currently, the obligation to submit SAF-T UA remains relevant primarily for large taxpayers upon the request of the supervisory authority within 2 working days. It is expected that legislative initiatives regarding automation and penalties will be reintroduced to the Verkhovna Rada in a new edition.<\/span><\/p>\nThis is an international standard for the electronic exchange of accounting data in a unified XML format, designed to simplify the submission of information to tax authorities and auditors during inspections. Ukraine is implementing this as SAF-T UA to automate electronic audits.<\/span><\/p>\niXBRL (Inline eXtensible Business Reporting Language)<\/span><\/h2>\n\niXBRL<\/strong> (Inline eXtensible Business Reporting Language) \u2014 \u00a0is a global electronic reporting standard that merges a <\/span>human-readable document format (which looks like a standard HTML report or PDF) with <\/span>machine-readable<\/span><\/p>\n<\/div>\n\nFinancial Reporting Taxonomy in XBRL format <\/a><\/strong>is an electronic file that defines the procedure for displaying financial reporting data using the principles of eXtensible Business Reporting Language (XBRL) based on the international standards financial reporting taxonomy.<\/span><\/p>\n<\/div>\nTaxonomy and iXBRL are two interconnected elements of a single electronic reporting system. To put it simply:<\/span><\/p>\n\n- Taxonomy is an electronic directory of all possible indicators. It is not the report file itself, but a set of rules and labels.<\/span><\/li>\n
- iXBRL is the technology that takes data from your accounting records, “labels” them with tags from the taxonomy, and packages everything into a user-friendly format.<\/span><\/li>\n<\/ul>\n
Taxonomy is “what” we write (the dictionary), while iXBRL is “how” we transmit it (the file format). The main difference is that taxonomy is a dictionary of terms, while iXBRL is the container in which these terms are delivered.<\/span><\/p>\nDual readability is achieved because a single iXBRL file can be viewed in a standard web browser as a visually appealing report, while computer programs and analytical tools can automatically extract structured data from it.<\/span><\/p>\nSpecific financial indicators (Assets, Revenue, etc.) are marked with special tags that define their meaning in accordance with international standards (for example, the IFRS Taxonomy). The use of harmonized taxonomies ensures transparency and accuracy, and simplifies the comparative analysis of financial information across different companies and countries.<\/span><\/p>\nGlobally, iXBRL is the standard for digital corporate reporting. It is mandatory for listed companies throughout the European Union and is also used by tax authorities and regulators in the US, UK, Japan, and many other countries. In Ukraine, submitting financial statements in iXBRL format based on the UA XBRL IFRS taxonomy is mandatory for enterprises and organizations that prepare financial statements under IFRS, particularly for public interest entities (large enterprises, banks, insurers, securities issuers, etc.). Reporting is submitted through the Financial Reporting System (FRS).<\/span><\/p>\nWho is Obligated to Report in iXBRL Format (as of 2026):
\nPublic interest entities, including large enterprises, banks, insurers, and securities issuers;<\/strong><\/span><\/p>\n\n- Extractive industry enterprises;<\/span><\/li>\n
- State-owned enterprises (where the state share exceeds 50%);<\/span><\/li>\n
- Other enterprises and organizations that have voluntarily chosen to apply IFRS.<\/span><\/li>\n<\/ul>\n<\/blockquote>\n
Advantages of Submitting Reports in iXBRL Format:
\nFor Business: Simplifies the reporting process (one file instead of two), reduces the risk of errors, and accelerates internal analysis.<\/strong><\/span><\/p>\n\n- For Investors and Analysts: Provides easy access to standardized, high-quality data, facilitating analysis and investment decision-making.<\/span><\/li>\n
- For Regulators: Automates the collection, processing, and verification of large volumes of financial data, helping to identify inconsistencies and potential violations.<\/span><\/li>\n<\/ul>\n<\/blockquote>\n
Regulatory Framework in Ukraine:
\nThe implementation and functioning of the iXBRL format taxonomy in Ukraine is regulated by a complex of legal acts:<\/strong><\/span><\/p>\n\n- Law of Ukraine “On Accounting and Financial Reporting in Ukraine” (Art. 11, par. 6): This norm directly establishes the obligation for IFRS-reporting entities to prepare and submit financial statements based on the financial reporting taxonomy in electronic format.<\/span><\/li>\n
- NSSMC (National Securities and Stock Market Commission): Resolution dated 06.06.2025 \u2116 36\/21\/2383\/K03 approved the requirements for disclosing financial reporting indicators in XBRL format for capital market participants. Since November 1, 2025, the option to submit IFRS reports in XML format has been cancelled \u2014 now only XBRL\/iXBRL is mandatory.<\/span><\/li>\n
- Ministry of Finance of Ukraine: Approves the updated UA IFRS XBRL taxonomy (as of 2026, the 2024 taxonomy is current for interim reporting for 2025 and earlier), which defines the composition of items and the logic of electronic report formation.<\/span><\/li>\n
- Technical Aspects: Reporting is submitted through the “Single Window” \u2014 a specialized portal of the Financial Reporting Collection Center (frs.gov.ua), operating on the basis of joint orders of the Ministry of Finance, the NBU, and the NSSMC.<\/span><\/li>\n<\/ol>\n<\/blockquote>\n\n
