Maintaining a mainland company in Abu Dhabi demands strict compliance practices. Licenses need annual renewal through the Department of Economic Development (DED), with associated fees. You must submit audited financials, file VAT/Corporate Tax returns if applicable, and adhere to labor laws, record keeping, and regulatory updates. Failure to comply can result in penalties, license suspension, or cancellation. Engaging a professional compliance partner or consultant helps monitor deadlines, ensure accurate filings, and manage evolving legal requirements in the UAE.
