Polish statutory reporting · JPK_CIT · JPK_VAT · NBP
Your Polish entity keeps its system. We handle the last mile to the ministry.
SimplyTax is not an accounting system and writes nothing back to yours. It builds the statutory file from what your system can already produce, validates it against the Polish Ministry of Finance's official XSD schema, lets you run the whole submission on the ministry's test gateway first, then submits and archives the official confirmation of receipt.
A note on terminology. Poland's JPK files are commonly described as SAF-T, but they follow their own national schemas published by the Polish Ministry of Finance and are not interchangeable with an OECD SAF-T export. TheUPO is the ministry's official confirmation that a filing was accepted; it is the evidence an auditor asks for, and we keep it rather than translating it away.
We do not ask which system you run. We ask what it can hand over.
There is no list of supported ERPs, deliberately. The translator is written for the source system — if we do not support yours yet, we write one; if we do, you arrive to something that already exists. A group with two hundred sites on one ERP still needs one translator, because it reads from one source.

- How we get your data — the three levels of integration, and what we never write back.
- The data specification — exactly what a file needs, field by field, before anyone builds one.
- SAF-T Poland (JPK_CIT) — who it covers, from when, and in what deadline.
Who you are contracting with
SimplyMobilePlus Sp. z o.o., registered in Łódź, Poland. SimplyTax is not our first product for a large organisation: we deliver workflow applications for large and very large organisations, and tax software to large and very large enterprises, with a dozen-plus references. Our KSeF product — built on the same mechanism as SimplyTax — runs in production at 6 customers. Procurement, security review and agreeing an integration with a group IT function are familiar ground rather than a first encounter.
Registration details are verifiable without asking us: NIP 7252310815, KRS 0000909729, both searchable in the Polish court register and the Ministry's VAT taxpayer list.
This site describes Polish reporting obligations and cites their primary sources. It is not tax advice, and it makes no statement about obligations outside Poland.
Let's check it against one of your files
Thirty minutes with the person who actually files these, not a presentation. The fastest way in is to tell us which system the data comes out of.
