What is “Contract-based Consulting”?

“Contract-based consulting” refers to a work style where individuals enter into a service contract (quasi-delegation agreement) rather than an employment contract with a company, utilizing their professional experience and expertise to perform specific work or projects.
Instead of working as a company employee, professionals participate in projects independently, providing problem-solving, technical support, and development consulting services.

This arrangement offers freedom from corporate constraints—allowing professionals to choose when, where, and how they work.
It is ideal not only for those seeking to continue their careers after retirement but also for full-time employees wishing to engage in side projects.
Individuals can balance this work with their main job or pursue it exclusively as a stable, independent career.

Frequently Asked Questions

Q
What is the difference between a contract-based agreement and an employment contract?
A

A contract-based agreement focuses on the completion of specific tasks or deliverables, allowing individuals to work without restrictions on time or location. However, unlike employment contracts, it does not include employee benefits or long-term salary guarantees. Freedom of work comes with the need for strong self-management.

Q
Can I take on contract-based work as a side job?
A

Yes, it is possible. Because contract-based work allows flexibility in time and location, many professionals pursue it alongside their main job, leveraging their expertise in a flexible way.

Q
Is tax filing required for contract-based work?
A

Yes, it is required. Income from contract-based work is subject to tax filing as business or miscellaneous income. Since taxes and social insurance contributions are self-managed, we recommend preparing proper accounting and tax arrangements in advance.
