Czech VAT Kontrolní

What it does

Kontrolni hlaseni XML export

A Pisemnost/DPHKH1 document with the header (VetaD — form KH1, period, riadne / opravne / nasledne filing type), the taxpayer identity (VetaP) and one element per transaction routed into the sections A.1, A.2, A.3, A.4, A.5 and B.1, B.2, B.3, plus the VetaC control totals.

Automatic section routing

Each posted invoice and bill is classified into its KH section from its VAT-inclusive value, the counterparty DIC and the reverse-charge / intra-EU flags, using the real 10,000 CZK threshold that splits the itemised A.4 / B.2 sections from the cumulative A.5 / B.3 lines.

DPH return (DPHDP3) figures

The same period is aggregated into the numbered VAT-return boxes (r1–r4 outputs, r25 reverse-charge supplied, r40 / r41 inputs, r43 / r44 reverse-charge received, r62–r65 settlement) and exported as a second EPO XML so the KH and the DPH return agree.

Real DIC / ICO / rodne cislo validation

The official ICO mod-11 check-digit algorithm, the rodne cislo (birth-number) date and mod-11 validity and the DIC (CZ VAT number) structure, applied on company and partner so a typo is caught before the file is built.

DPH rate buckets

The 21% standard rate, the 12% reduced rate and a legacy reduced-rate slot, with per-bucket base and tax aggregation so a single document can carry both a standard and a reduced component.

Kontrolni hlaseni business-rule validation

A Czech rule set layered on the shared engine's EN 16931-style core: taxpayer DIC, CZK currency, valid rate categories, a counterparty DIC on the itemised sections and credit-note referencing, surfaced before export.
