Ukraine: Kharkiv Issues 17,700 Qualified Electronic Certificates in Nine Months

The 28 October 2026 update from the Kharkiv Tax Administration reveals that 17,700 qualified electronic signature certificates were issued to individuals and legal entities between January and September 2026. Issuance is performed by the State Tax Service’s accredited Qualified Trust Service Provider (CA.tax.gov.ua) under the Law on Electronic Trust Services (No. 2155-IX). Certificates are mandatory for signing tax returns, customs declarations, and participating in public e-procurement. The 22% growth reflects mandatory e-filing expansion for VAT payers and the “Diia.Sign” mobile app integration.

Key Takeaways

  • Mobile-First Adoption: Diia.Sign accounted for 64% of new certificates, lowering entry barriers for sole proprietors and SMEs.
  • Cross-Service Interoperability: Certificates are recognized across all e-government portals (Diia, Prozorro, Electronic Cabinet), creating a unified digital identity layer.
