Providing support to Croatian subcontractors in Belgium
Navigating Belgium’s labor law, tax, immigration, social security and other regulations can be quite challenging for foreign contractors. That’s why we have set up a pragmatic and hands-on cooperation specifically designed to support Croatian subcontracting companies working on construction or industrial sites in Belgium. Our goal is to guide you through every step of the process and address all your questions. From compliance support in areas like personal income tax, corporate tax, VAT, labor law, social security and immigration, to advisory and compliance reviews, we ensure a smooth and compliant experience for you and your workforce both in Belgium and in Croatia.
Belgium is renowned for its stringent compliance requirements in the construction industry. Both main contractors and Belgian authorities enforce these regulations rigorously, conducting thorough checks on employment conditions, work permits, social security, and taxation. Non-compliance can lead to significant penalties and project delays. In the past years, several scandals involving illegal employment and human trafficking have been uncovered on constructions sites, prompting Belgian authorities and main contractors to increase on-site inspections/audits to ensure all formalities in the hands of the subcontractor chain are met.
Ensuring compliance is essential for securing your business’s future in the Belgian market. Therefore, it is crucial to be well-prepared and fully compliant when sending workers to Belgium.
Become aware of the need to be and remain compliant
Have you asked yourself the following questions?
- Did you check the minimum wages and sectoral obligations when working in Belgium?
- Did you know that depending on the length of the project in Belgium, you must comply with corporate income tax formalities?
- Are you aware that overtime is limited in Belgium?
- Did you know that daily allowances paid to the workers could be considered taxable salary in Belgium?
If your answer is no to any of these questions, you might not be in compliance with local regulations and you could face severe penalties.
