How to add a member to your LLC.

Look for amendment provisions: typically requires unanimous or majority consent. Also check for transfer restrictions and any preemptive rights of existing members.

Pass the resolution to admit the new member at the consent threshold required by the operating agreement. Document with a written consent or meeting minutes.

Capital contribution from new member, ownership percentage, voting rights, profit/loss allocation, management role, vesting (if any). All should be in the amendment.

Written amendment signed by all members reflecting new ownership structure, contribution, allocations, and any other modified terms. The new member also signs onto the amended operating agreement.

Some states require amendment to the Articles of Organization when members change (especially manager-managed LLCs where managers are listed publicly). Many do not. We check your state requirements.

Single-member adding a second member: LLC converts from disregarded entity to partnership for tax purposes. New EIN may be needed; partnership tax return (Form 1065) now required. If S-Corp elected: ensure new member is eligible (US person, individual or qualifying entity).

FinCEN requires update within 30 days of any change to beneficial owners. New member reaches 25%+ ownership = required filing.

Bank signature cards, payment processors, vendor accounts. Tell counterparties about the new authorized signer where applicable.
