To add a member to an LLC in Maryland, you follow your operating agreement’s admission procedure, get the required member approvals, and sign a written amendment that admits the new person and records their contribution and ownership share. Maryland’s Department of Assessments and Taxation (SDAT) does not require a filing just because ownership changes. The work is internal, but it has to be done carefully: a sloppy admission can create tax problems, ownership disputes, and liability confusion that cost far more to fix later than to do right the first time.
Start With Your Operating Agreement
Pull out your operating agreement before anything else. It is the controlling document, and it usually spells out how new members are admitted: the vote threshold required, any restrictions on who can join, minimum capital contributions, and whether existing members have a right of first refusal to match an outside offer.
Maryland’s LLC Act gives operating agreements wide latitude to set these rules, including the circumstances under which someone may be admitted, how interests may be assigned, voting procedures, and profit-sharing. If your agreement requires a supermajority vote or a specific buy-in, those terms control. Follow them exactly. An admission that skips a step your own agreement requires is vulnerable to being challenged later.
If your LLC never adopted an operating agreement, Maryland’s default rule applies: under § 4A-601 of the Corporations and Associations Code, a person acquiring an interest directly from the LLC can only be admitted with the unanimous consent of all existing members.1New York Codes, Rules and Regulations. Maryland Code Corps and Assns 4A-601 – Conditions for Admission as Member The same unanimous-consent default applies when someone who was assigned an existing member’s interest wants to become a full member.2New York Codes, Rules and Regulations. Maryland Code Corps and Assns 4A-604 – Rights and Obligations of Assignee Without a written agreement, one holdout member can block an admission the rest of you want. If that’s your situation, drafting an operating agreement should happen before, or alongside, the admission.
Admit the Person as a Member, Not Just an Assignee
Maryland draws a sharp line between someone who holds an economic interest in your LLC and someone who is actually a member. This trips people up constantly, especially when an existing member sells part of their interest to a third party.
Under § 4A-603, assigning an economic interest to someone does not make that person a member. The assignee gets only financial rights, meaning a share of profits and distributions. They cannot vote, participate in management, or access company records.3FindLaw. Maryland Code Corps and Assns 4A-603 And if the assigning member transfers all of their economic interest, that member forfeits their own membership status and loses their voting rights too.
For the new person to become a full member, your operating agreement has to allow it, or every existing member has to unanimously consent.2New York Codes, Rules and Regulations. Maryland Code Corps and Assns 4A-604 – Rights and Obligations of Assignee An assignee who is admitted as a member also takes on the original member’s obligation to make any outstanding capital contributions. The practical point: make sure your paperwork explicitly admits the new person as a member. Don’t leave it as a transfer of economic interest and assume the rest follows.
Put the Admission in Writing
Once you have the required approvals, formalize the admission by amending your operating agreement, or drafting a new one if the original is thin. This document is the legal backbone of the new member’s relationship with the LLC and every other member. At a minimum, it should cover:
- The new member’s full legal name and address.
- What they are contributing. Maryland defines a capital contribution broadly, so it can be cash, property, services, or a binding promise to contribute later. For non-cash contributions, state the fair market value the members have agreed on.4Maryland General Assembly. Maryland Code Corps and Assns 4A-101 – Definitions
- The new member’s ownership percentage, along with any adjustments to existing members’ percentages.
- How profits and losses will be allocated going forward. This does not have to mirror ownership percentages, but it needs to be explicit.
- The effective date of the admission, which matters for tax purposes.
Every existing member and the new member should sign. If your operating agreement specifies how amendments are made, follow that procedure to the letter.
Two side issues often come up at this stage. First, valuation: if the new member is buying into an established business, you need to know what the company is worth. When everyone agrees on value, an informal number can work; when the stakes are higher or the IRS is likely to look, a professional valuation runs roughly $2,000 to $10,000 for a standard engagement. Second, vesting: if the new member is earning their interest over time through continued service, the operating agreement needs custom-drafted vesting terms, because there is no off-the-shelf template for LLC interests. Many smaller LLCs skip vesting and require the full contribution upfront. If you do use vesting, spell out what happens to unvested interests if the member leaves early.
When You Do (and Don’t) File With SDAT
Adding a member by itself requires no filing with SDAT. Maryland treats membership changes as internal. You are not required to report your members to the state, and the annual report does not include a field for member identities.
You only file Articles of Amendment with SDAT if the admission triggers a change to something in your articles of organization. The usual triggers:
- You are renaming the LLC as part of the restructuring.
- You are relocating the principal office.
- You are switching between member-managed and manager-managed, or the reverse, as part of the new arrangement.
The filing fee for Articles of Amendment is $100, with an additional $150 for expedited processing.5Maryland State Department of Assessments and Taxation. Articles of Amendment for a Limited Liability Company
The Tax Change You Cannot Ignore
Federal tax classification depends on how many members your LLC has. A single-member LLC is treated as a disregarded entity, meaning income is reported on the owner’s personal return. A multi-member LLC defaults to partnership classification.6eCFR. 26 CFR 301.7701-3 – Classification of Certain Business Entities That change happens automatically the moment a second member is admitted.
Once your LLC has two or more members, you will need to file Form 1065 (U.S. Return of Partnership Income) annually with the IRS.7Internal Revenue Service. About Form 1065, U.S. Return of Partnership Income Each member also receives a Schedule K-1 showing their share of the LLC’s income, deductions, and credits, which they report on their personal returns. If you already had an EIN as a single-member LLC, you generally continue using the same EIN after the classification change.
A multi-member LLC does not have to accept partnership taxation. It can elect corporate taxation by filing Form 8832,8Internal Revenue Service. Form 8832 – Entity Classification Election or S corporation status by filing Form 2553. Each election has its own eligibility rules and deadlines, and each has significant consequences. Talk these through with a tax professional before the new member joins, not after.
Beneficial Ownership Reporting
If you are worried about the federal Beneficial Ownership Information (BOI) requirement under the Corporate Transparency Act, you can set that concern aside for a domestic Maryland LLC. As of March 2025, FinCEN revised its rules so that all entities formed in the United States, and all U.S. persons who are beneficial owners of those entities, are exempt from BOI reporting. The requirement now applies only to foreign entities registered to do business in a U.S. state.9FinCEN. Beneficial Ownership Information Reporting For a Maryland-formed LLC adding a domestic member, no BOI filing is needed.
What It Costs
Direct state cost is zero unless you also amend your articles of organization, in which case the SDAT fee is $100 ($250 expedited). The larger expenses are professional. Attorney fees for drafting an operating agreement amendment typically run $600 to $1,700 depending on complexity. A professional business valuation, if you need one, runs $2,000 to $10,000. A tax advisor’s time on the classification change and any elections adds to the total. For a straightforward admission to a small LLC where everyone agrees on terms, you can keep the total well under $2,000. Contested valuations or vesting arrangements push it considerably higher.
