Invoice format and locale facts for Slovakia

Why these defaults?

The country code comes from ISO 3166. Unicode CLDR supplies presentation-oriented locale, currency, paper, date, language, calendar, numbering, and direction metadata. Defaults reduce setup time; they do not decide what a valid document must contain.

Document vocabulary and checks

Core Slovak VAT-invoice particulars, simplified/correction context, ten-year invoice retention and the structured XML BIS/Peppol/certified-provider boundary are reviewed from Financial Administration guidance. This local Faktúra is not a regulated structured e-invoice and does not onboard a provider, create or validate XML, deliver through Peppol or report to the authority. Applicability, transition dates and transaction-specific DPH treatment remain current-rule checks.

• Required when applicable: A Slovak VAT invoice identifies supplier and recipient with the applicable VAT numbers, carries a sequential invoice number, supply/payment and issue dates, describes quantity and type of goods or extent and type of services, and states the tax base, VAT-exclusive unit price and discounts, rate and VAT amount in euros. Simplified and correction invoices have adjusted particulars.Evidence SK_FINANCIAL_ADMIN_INVOICING · reviewed 2026-07-19 · review by 2027-01-19 · automation advisory only
• Required when applicable: Issued and received VAT invoices are generally retained for ten years following the year to which they relate. Investment-property, customs and unresolved matters can require different or longer preservation, and electronic storage must preserve access, authenticity, integrity and readability.Evidence SK_FINANCIAL_ADMIN_INVOICING · reviewed 2026-07-19 · review by 2027-01-19 · automation advisory only
• Required when applicable: Slovakia's structured e-invoice programme uses XML BIS/Peppol through certified delivery providers; a PDF or scan is not the regulated structured invoice. This preview neither creates XML BIS, connects to Peppol or a certified provider, guarantees delivery, nor reports invoice data to the Financial Administration.Evidence SK_FINANCIAL_ADMIN_EINVOICE, SK_FINANCIAL_ADMIN_INVOICING · reviewed 2026-07-19 · review by 2027-01-19 · automation advisory only
