Applying for A1 certificates in Croatia is done via post sent to the Croatian social security agency (HMZO).
Processing times are usually around 1 month, though it may take longer depending on the case. The key challenge is that WorkFlex must attain several documents from the employee and the employer.
✅ What you need to do
1. Sign a Power of Attorney (POA) and an employer questionnaire
We will provide you with a POA template. Please sign and return it to us.
We will provide you with the employer questionnaire. Please fill it and sign it, then return it to us.
2. Have the employee upload their documents on the document center
The employee should upload their employment contract.
⚠️ Key points to bear in mind
A POA is always required.
The employer receives the A1 certificate. Upon recipient, the certificate should be sent directly to the email social.security@getworkflex.
👉 Once these steps are complete, WorkFlex will handle the A1 application process fully on your behalf.
