Short version: when identified person registration or monthly filing is late, the first priority is not another general article. The priority is to stop the delay from growing, map the missing periods and close the history in the right order.
This page owns one urgent intent only: penalty / missed identified person filing / overdue filing fix. If you only need the legal base, go to identified person in the Czech Republic. If the backlog resolution should turn into a stable process afterwards, go to monthly VAT filing.
1. What to do first
- Confirm which periods are missing.
- Collect the platform reports or foreign invoices for those periods.
- Close the highest-risk months first, especially if the tax office already reacted.
2. What not to do
- Do not answer blindly without the period map.
- Do not file only the latest month and ignore older gaps.
- Do not assume a “zero month” automatically needs nothing.
3. The hand-off after the backlog fix
The backlog fix is not the finish line. After the missing history is closed, the business still needs a stable monthly routine. That is why this page hands off into monthly VAT filing and not into more catch-up reading.
