LLP annual filing is a mandatory compliance requirement for limited liability partnerships in India. Entities must submit two forms annually: Form 8 for financial statements and Form 11 for partner details. The filing process involves preparing documents, logging into the MCA portal, uploading forms, attaching required documents, paying fees, and completing verification. Late filings incur penalties of Rs. 100 per day, with potential risk of being struck off if consistently non-compliant.
