Form 18 explained: this guide covers what it means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.
Four conditions must already be true before the form can be filed — and each of them takes time to fix if it is not.
Who may convert
This form is applicable for conversion of an existing private limited company or unlisted public company into LLP. The statutory routes are separate:
Section 56: "A private company may convert into a limited liability partnership in accordance with the provisions of this Chapter and the Third Schedule."
Section 57: "An unlisted public company may convert into a limited liability partnership in accordance with the provisions of this Chapter and the Fourth Schedule."
Rules 39(1) and 40(1) prescribe the same form for both — an application in the format provided in Part A of Form 18 together with the statement of shareholders in format provided in Part B of Form 18.
Unlike a firm conversion, a company conversion has entry conditions that must already be satisfied on the day of filing:
No pending e-forms. The company shall ensure that no e-forms are pending for payment or processing in respect of the company. An unpaid or in-process filing blocks the conversion — the same queueing logic that governs Forms 3 and 4.
No unsatisfied charges. There are no unsatisfied charges that are pending against the company. This is the substantial one. Every registered charge must be satisfied and the satisfaction filed, which means secured borrowing must be repaid or refinanced before conversion — not merely consented to, as with a firm.
Share capital. The company should be having share capital. A company limited by guarantee without share capital cannot use this route.
A filing history. After its incorporation as company, it had at least filed one balance sheet and annual return with the Registrar. A newly incorporated company must complete one full reporting cycle first.
Read together, these conditions mean a company conversion has a lead time measured in months rather than weeks. Charge satisfaction alone requires lender cooperation and Registrar filings, and a company that has not yet filed its first annual return simply has to wait.
Note one difference from the firm route: the statement of assets and liabilities must be duly certified as true and correct by the auditor — the company's own statutory auditor — rather than by any chartered accountant in practice.

Filing mechanics
Form 18 is required to be filed together with FiLLiP form, and the name may be reserved in advance through RUN-LLP or proposed within FiLLiP. As with the firm route, the tax aspects are not been considered in the filing checklist and must be advised on separately.
Common mistakes
- Beginning a Form 18 conversion with charges still on the register.
- Attempting conversion of a company without share capital.
- Filing before the first balance sheet and annual return have been filed.
- Obtaining the assets and liabilities certificate from a professional other than the auditor.
