Filing a ds01 online is the simplest way to dissolve a company in the UK. The DS01 form, also known as the "Strike Off" application, allows company directors to voluntarily close their business. Submitting it online through Companies House is faster and more convenient than paper forms. Before applying, ensure that the company has settled all debts and ceased trading. Filing the DS01 online saves time and ensures smooth processing, making the dissolution process more efficient and accessible.
