Poland JPK_VAT

What it does

JPK_V7M / JPK_V7K export

The combined register + declaration file in two variants: JPK_V7M — the monthly filer's file (ewidencja + deklaracja every month); JPK_V7K — the quarterly filer's file (the ewidencja monthly, the deklaracja only with the third month of each quarter).

Full file structure

Naglowek (header: form code, system version, purpose-of-submission, period, tax-office code), Podmiot1 (taxpayer NIP / name / e-mail), Deklaracja (the P_ positions computed from the register) and Ewidencja (SprzedazWiersz sales rows + SprzedazCtrl, ZakupWiersz purchase rows + ZakupCtrl control sums).

KSeF-era field mapping

Each register row optionally carries the 35-character KSeF reference number (NrKSeF) the National e-Invoice System assigns to a cleared structured invoice, so the JPK_VAT ties back to the KSeF clearance — ready for the 2026 mandate.

Real Polish identifier validation

The official check-digit algorithms for the NIP (10-digit, mod-11 weighted), the REGON (9- and 14-digit) and the PESEL (11-digit personal number with embedded-date plausibility), applied on the company and partner.

VAT-rate mapping

Poland's 23% standard, 8% and 5% reduced, 0%, and exempt (zw) / out-of-scope (np) buckets mapped to the correct JPK register K-fields and declaration P-positions.

Period export model

Pick a variant, year and month; Odoo collects the posted sales / purchase documents, builds the file, stores it as a downloadable attachment and records the row / VAT totals.

JPK_VAT business-rule validation

A Poland rule set layered on the engine's EN 16931-style core: company NIP, PLN currency, register K-codes, the BRAK final-consumer placeholder for cash-register sales and correction referencing.

Editable Ministry-of-Finance defaults

The destination tax-office code and contact e-mail are held on the company record. An onboarding wizard, an optional flag-pending cron and the e-Invoicing menu round out the connector; nothing is bundled or sent except the file you generate and submit.

Built for Poland

Authority: Ministry of Finance (Ministerstwo Finansów), KAS gateway. Format: JPK_V7M / JPK_V7K on schema (3), http://crd.gov.pl/wzor/2025/12/19/14090/ / .../14089/. Currency: Polish złoty (PLN). The connector builds on the shared e-Invoice Core Engine (validation framework and profile registry) and registers its own Polish profile and validation rule set.

Disclosure: this module generates a JPK_V7M / JPK_V7K XML file locally for you to download and submit to the Ministry of Finance. It transmits nothing on its own; your NIP, REGON and tax-office code are stored solely on your own database.
