After registering an LLP, it must adhere to several compliance requirements, including:

Annual Return Filing: LLPs must file an annual return (Form 11) with the Registrar of Companies (ROC) within 60 days from the close of the financial year.
Statement of Accounts and Solvency: LLPs must maintain proper books of account and file a statement of accounts and solvency (Form 8) within 30 days from the end of six months of the financial year.
Income Tax Return: LLPs must file their income tax return annually by the due date, which is typically July 31st for LLPs not requiring an audit and September 30th for those that do.
Other Filings: Depending on the LLP's activities, additional filings such as GST returns, TDS returns, and other regulatory compliances may be necessary.
