Can I close a dormant B.V. quickly?

Yes, through fast-track liquidation, if the B.V. has no assets left at dissolution, including cash or money still owed to it. You file the dissolution resolution, a balance sheet and a profit and loss account with KVK. If a creditor later shows the conditions were not met, the former directors can be held liable.
