What an identified person must file: the full checklist without confusion

Short version: an identified person usually deals with four layers: registration within 15 days, monthly VAT filing by the 25th day of the following month, a summary statement only in relevant cases, and outside the VAT layer an annual tax return plus follow-up social and health filings.

This page exists to answer one exact operational question: what must an identified person actually file? If you still need the scope question first, go to who needs identified person status. If you already need the monthly routine only, go to monthly VAT filing.

1. The whole filing stack in one table

What you file	When	Why
Identified person registration	Within 15 days from the start of the obligation	Formal entry into the regime
Monthly VAT return	By the 25th day of the following month	VAT layer for relevant cross-border services
Summary statement	By the 25th day after the period	Only if the relevant EU service scenario applies
Annual self-employed tax return	According to the annual tax deadline	Income tax layer for the business year

2. Registration is the first step, not the final solution

The common mistake is treating registration like the finish line. It is only the entry point. The real operating stability starts when registration is immediately followed by the monthly filing routine.

3. Monthly VAT is the core operating layer

1. Close the month with final platform or supplier data.
2. Confirm what belongs in the period.
3. File the VAT return before the 25th day.
4. Store the filing and payment evidence for the annual layer.

4. Summary statement is not automatic for everyone

Not every identified person files a summary statement. That depends on whether you provide relevant services into another EU country under the reverse charge logic. Many drivers only deal with the incoming foreign platform service and therefore focus mainly on registration plus the monthly VAT return.

5. What still exists outside the IO layer

Identified person status does not replace the annual self-employed tax return. It does not remove social and health filings either. That is why the clean process is not “one tax thing”, but a stack of separate duties that must stay synchronized.

6. What to archive every month

• final platform report or foreign invoice,
• internal VAT calculation,
• filing confirmation,
• payment proof,
• a short note if the month was unusual.

If you want the document pack for all these filings in one place, continue to identified person and tax return checklist. If you want the annual layer itself, go to self-employed tax return in the Czech Republic. If you are still deciding whether the business should remain in IO at all, go to identified person vs VAT payer.
