VATCalc explains how the EU’s 2028 Customs Reform will eliminate the €150 low‑value threshold, expand platform liability, and require real‑time, transaction‑level VAT determination and reporting. The article argues that legacy VAT systems are ill‑suited and that a single, legislative‑coded engine is essential to meet the new harmonised import VAT model across all 27 Member States. It highlights the need for rapid, integrated compliance to avoid penalties and operational risk.

The EU’s VAT in the Digital Age (ViDA) reforms are accelerating the shift toward transaction‑level digital reporting, mandatory e‑invoicing, and real‑time compliance. Legacy ERP tax engines struggle to adapt to the fragmented, rapidly evolving national implementations, while VATCalc’s legislatively‑coded, serverless architecture offers a scalable, integrated solution. Businesses must evaluate whether their tax engine can pivot quickly without repeated reinvestment to meet ViDA’s requirements.

Slovenia launched mandatory electronic VAT reporting (e-poročanje) in July 2025, requiring all VAT-registered businesses to submit records through the e-Davki portal. B2B e-invoicing follows in 2027.
