How does a contractor agreement differ from a service agreement?

A service agreement is tied to a specific result (a deliverable). A contractor agreement can cover ongoing services and consultations without a defined output. For long-term relationships a contractor agreement is more flexible.

Can a contractor work for multiple clients at the same time?

Yes, unless the contract includes an exclusivity clause. Exclusivity must be expressly agreed and is usually compensated with a higher fee.

What if the tax authority reclassifies the contractor relationship as employment?

The client (as de facto employer) would have to pay back social contributions and taxes for the entire period of the relationship. The contract should emphasise signs of a business relationship: independence, own equipment, multiple clients.

How long can a contractor relationship last?

There is no statutory maximum. Long-term contractor relationships carry a higher reclassification risk — the longer and more exclusive the relationship, the greater the risk. We recommend renewing the contract regularly and documenting the business nature of the relationship.
