Country · Premium Worker
The proximity to Slovakia makes project logistics easier, but does not replace checking the Austrian rules. The distinction between genuine self-employed persons and posted employees is important. Our teams work as self-employed subcontractors; the actual organisation and required documents are coordinated in advance.

Prepare the assignment
The applicable social security is documented via the A1. The certificate does not replace checking trade or notification obligations.
ZKO3 concerns the posting of employees. It is not a blanket obligation for genuinely self-employed persons working personally. For dependent or employee-like relationships, the classification must be checked separately.
For employee postings, retention rules apply to notification, social security and pay documents, among others. For genuine self-employed persons we coordinate proof of contract and status.
Check possible service notifications and local requirements per trade. The contract designation and the actual site organisation must match.
No legal advice – please review individual cases with your tax adviser or lawyer.
