Does an LLC automatically dissolve when the owner dies?

Not automatically, but a single-member LLC can dissolve if nobody acts in time. Under the uniform LLC act adopted in most states, an individual member's death causes that person to be dissociated from the company -- California codifies this at Corporations Code section 17706.02(f)(1). Dissociation is not the same as dissolution: in a multi-member LLC the company keeps operating and the estate is left holding an economic interest. The risk is concentrated in single-member LLCs, where the death leaves the company with no members. Delaware section 18-801(a)(4) is the clearest example of the rule: the LLC dissolves unless, within 90 days of the event that ended the last member's membership (or another period set in the operating agreement), the personal representative of the last remaining member agrees to continue the company and to the admission of the representative or their nominee as a member. Read the operating agreement early -- that window starts running at the date of death, not at the date you are appointed.

Can an estate be a shareholder of an S corporation?

Yes. An estate is one of the few non-individual shareholders an S corporation is permitted to have. Section 1361(b)(1)(B) of the Internal Revenue Code bars an S corporation from having a shareholder that is not an individual, other than an estate, certain trusts described in subsection (c)(2), and certain exempt organizations. So the estate can hold the stock while it settles without blowing the S election. What is time-limited is what comes next: under section 1361(c)(2)(A)(iii), a trust that receives S corporation stock pursuant to a will may be a shareholder only for the two-year period beginning on the day the stock is transferred to it. If the will leaves the stock to a trust, that trust needs to qualify some other way -- as a QSST or an ESBT, for example -- before the two years run out, or the S election is at risk. This is the point in a business estate where a CPA's time is usually worth what it costs.

Do I need a new EIN for a sole proprietorship after the owner dies?

Yes, if the estate keeps operating the business. The IRS's own guidance on when a new EIN is required lists this case directly: you need a new EIN to represent an estate that operates a business that is not a legal entity separate from its owner -- a sole proprietorship -- after the owner's death, and the new EIN will be for the business. That is separate from the EIN the estate itself needs for its own income tax reporting. A sole proprietorship has no legal existence apart from the person who ran it, so there is no entity to inherit; what the estate inherits is the assets, and the deceased's own sole-proprietor EIN does not carry forward. If the business is an LLC or a corporation, the entity survives the owner and generally keeps its existing EIN.

Does the executor inherit the right to run the business?

It depends on the entity, and for LLCs the default answer is usually no. Most states separate an LLC interest into an economic piece (the right to distributions) and a governance piece (the right to vote and manage), and what passes on death is generally only the economic piece. California Corporations Code section 17705.02 provides that a transferee may not vote or otherwise participate in the management or conduct of the company's activities. Section 17705.04 then gives the deceased member's personal representative the rights of a transferee plus, for the purposes of settling the estate, the rights of a current member under the information-access statute -- in other words, enough authority to get records and administer the interest, not to run the company. Delaware is broader: section 18-705 says the personal representative of a deceased individual member may exercise all of the member's rights for the purpose of settling the estate or administering the property. Check the state of formation and the operating agreement, in that order.

What is a buy-sell agreement and how do I find out if there is one?

A buy-sell agreement is a contract among the owners of a closely held business that says what happens to an owner's interest on a triggering event -- most often death, disability, divorce, or a decision to leave. It typically fixes who may buy, how the price is determined, and how the purchase is funded, and it is frequently backed by life insurance on each owner so the money is there when the trigger hits. If one exists, it usually controls, and it can override what the will says about the business interest. Look for it in the same places you would look for an operating agreement: the business's corporate record book, the deceased's files, the company's attorney or CPA, and the surviving owners. Also look for life insurance policies where the business or a co-owner is the owner or beneficiary rather than a family member -- that is often the funding mechanism, and it is easy to miss on an inventory.

Who is responsible for the business's payroll and taxes after the owner dies?

The business is, and in practice that means whoever has authority to act for it -- which is the problem, because that authority often does not exist for a few weeks. Payroll deadlines, employment tax deposits, sales tax filings, insurance premiums, and loan payments do not pause for probate. Two things buy you time. First, find out whether anyone else already has signature authority on the business bank account or is named in the operating agreement as a successor manager; that person can often keep the lights on immediately. Second, if you are the personal representative, get certified letters as quickly as you can, and tell the IRS about the change in responsible party -- Form 8822-B is the vehicle, and the IRS requires changes in responsible parties to be reported within 60 days. Do not pay business obligations out of your own pocket without recording it; those are estate or company expenses and need to be documented as such.

What Happens to a Business When the Owner Dies

The Business Does Not Wait

Most of probate moves at the speed of the court. A business does not. Payroll runs on Friday. The lease is due on the first. A customer is waiting on an order that was half-finished the week the owner died, and the only person with the password to the invoicing system is gone.

That mismatch -- a court process measured in months, a business measured in days -- is what makes a business interest the single most time-sensitive asset in a lot of estates. And it is the asset most likely to be handled wrong, because "the business" is not one thing. A sole proprietorship, a single-member LLC, a half share of a partnership, and stock in an S corporation are four entirely different legal animals, and they behave in four entirely different ways after a death.

This guide covers how to figure out which one you are dealing with, what the estate actually receives in each case, the short deadlines that catch people out, and what to do in the first two weeks.

Attorney rules vary by state

A handful of states require a licensed attorney to administer probate — Arkansas, Illinois, Mississippi, and South Dakota, plus (for most estates) Florida, Louisiana, Missouri, Texas, and Wisconsin; California and New York generally let you handle routine administration yourself but require an attorney for contested matters; Indiana and Tennessee depend on the county. Check your state probate guide before assuming you can handle everything yourself.

Step One: Identify the Entity

Before anything else, answer one question: what legal form was the business?

People are often wrong about this, including the family. "He had his own business" can mean a sole proprietorship with no filings anywhere, or a single-member LLC registered in another state, or an S corporation that has been filing Form 1120-S for fifteen years. The answer changes everything downstream, so establish it from documents rather than memory.

Where to look:

Tax returns. This is the fastest tell. A Schedule C attached to the personal Form 1040 means a sole proprietorship or a single-member LLC treated as a disregarded entity. A Schedule K-1 means a partnership, a multi-member LLC, or an S corporation -- and the K-1 itself names the entity and its EIN. A Form 1120-S in the files means an S corporation; Form 1065 means a partnership or multi-member LLC.
The Secretary of State's business search. Every state runs a free online entity search. Look up the business name and the deceased's name. This tells you the entity type, the state of formation, the registered agent, and whether the entity is currently in good standing -- which matters, because a business that has lapsed for unpaid annual reports is a different problem.
The corporate record book or entity folder. Operating agreements, bylaws, stock certificates, partnership agreements, buy-sell agreements, and minutes usually live in one binder or one drawer.
The business bank account. The signature card shows the account's legal owner and who else has authority on it.
The deceased's CPA and attorney. They can often answer the entity question in one phone call, and they usually know whether a buy-sell agreement exists.

Formation state, not home state

An LLC's internal rules are governed by the law of the state where it was formed, which is not always where the owner lived or where the business operated. A Nevada or Delaware LLC run out of a house in Ohio follows Nevada or Delaware law on questions like dissociation and dissolution. Confirm the formation state before you read any statute.

Sole Proprietorship: There Is No Entity to Inherit

A sole proprietorship is not a separate legal thing. It is a person doing business, plus whatever name they registered as a DBA. That has one large consequence: the business does not survive the owner, because there was never anything separate from the owner to survive.

What exists after the death is a pile of assets and liabilities that now belong to the estate -- equipment, inventory, receivables, the customer list, the domain name, the vehicle, the lease, the accounts payable. Those flow through the will, or through intestacy if there is no will, the same as any other property. See who counts as an heir if there is no will directing where they go.

Practical consequences:

The DBA does not transfer on its own. A fictitious-name registration is tied to the registrant. If an heir wants to keep operating under that name, they generally register it themselves.
Contracts may not survive. Many service contracts are personal to the provider and end at death. Others assign to the estate. This is contract-by-contract reading, not a general rule.
Professional licenses do not transfer, ever. A contractor's license, a cosmetology license, a real estate license -- none of these pass to an heir. If the business legally required a licensed person to operate, it usually cannot keep operating without one.
The estate needs a new EIN to keep running it. The IRS's guidance on when a new EIN is required is explicit: you need one to represent an estate that operates a business that is not a legal entity separate from its owner -- a sole proprietorship -- after the owner's death, and that new EIN is for the business (IRS, Do you need a new EIN?). This is in addition to the EIN the estate needs for its own reporting; see how to get an EIN for an estate.

In most sole proprietorship cases the realistic outcomes are: sell the assets, wind the business down, or have an heir start a new business and buy the assets from the estate at fair value. Continuing to operate indefinitely as "the estate" is rarely the right answer, because every month of operation is a month of business risk carried by the estate.

Single-Member LLC: The 90-Day Trap

This is the case with a real deadline attached, and the one most likely to go wrong quietly.

Under the uniform LLC act adopted in most states, the death of an individual member causes that person to be dissociated from the company. California states it plainly at Corporations Code section 17706.02(f)(1): a person is dissociated when "the person dies."

In a multi-member LLC that is survivable -- the company keeps going with its remaining members. In a single-member LLC, dissociating the only member leaves the company with no members at all, and an LLC with no members is on a clock.

Delaware's version is the clearest statement of the rule. Section 18-801(a)(4) dissolves an LLC when it has no members, unless within 90 days of the event that terminated the last remaining member's membership -- or another period set in the LLC agreement -- the personal representative of that last member agrees to continue the company and to the admission of the representative, or a nominee or designee, as a member.

Read that timing carefully. The 90 days run from the date of death, not from the date the court appoints you. In plenty of estates, appointment alone takes six to ten weeks. If nobody has looked at the operating agreement in the meantime, the window can close before the personal representative even has letters in hand.

What to do:

Find the operating agreement immediately and read the death, dissociation, and dissolution provisions. A well-drafted agreement often addresses this directly and may extend or replace the statutory window.
Confirm the formation state and look up its version of the rule. States that adopted the uniform act use similar language; some use different periods.
If a written continuation or consent is required, get it signed and dated within the window, and keep it with the entity records.
If you are not yet appointed, this is a reason to push the probate filing to the front of the queue rather than treating it as routine. Letters testamentary are what banks and counterparties will ask for.

Do not assume the LLC is safe because it is still filing

An LLC can be technically dissolved under the statute while the state's records still show it as active and the bank account still works. Administrative status and legal status are separate questions, and the mismatch tends to surface later -- during a sale, a financing, or a dispute -- when it is expensive to fix.

Multi-Member LLC: Economic Rights, Not Control

When one member of a multi-member LLC dies, the company keeps operating. The question becomes what the estate actually holds.

Most states split an LLC interest in two: the transferable interest (the economic right to receive distributions) and the governance rights (voting, management, information). What passes on death is generally the economic piece only.

California's statute is representative. Section 17705.02 provides that a transferee may not vote or otherwise participate in the management or conduct of the company's activities. Section 17705.04 then addresses the estate directly: "If a member dies, the deceased member's personal representative or other legal representative may exercise the rights of a transferee provided in subdivision (c) of Section 17705.02 and, for the purposes of settling the estate, the rights of a current member under Section 17704.10" -- the information and records provision.

So in California the personal representative can collect distributions and get at the books, but cannot vote the interest or direct the business.

Delaware is meaningfully broader. Section 18-705 provides that if an individual member dies, "the member's personal representative may exercise all of the member's rights for the purpose of settling the member's estate or administering the member's property, including any power under a limited liability company agreement of an assignee to become a member."

Two states, two different answers, same fact pattern. This is exactly why the formation state has to be settled before anyone relies on a general rule they read online.

Whatever the default is, the operating agreement usually beats it. Many agreements contain a mandatory purchase obligation on death, a right of first refusal for surviving members, a valuation formula, and a payment schedule. If one exists, that document -- not the will -- typically determines what the estate receives.

Partnerships

A general partnership behaves similarly to a multi-member LLC. Under the uniform partnership act, a partner's death causes dissociation; California codifies it at Corporations Code section 16601(7)(A) as simply "the partner's death."

Dissociation does not necessarily dissolve the partnership. In most cases the remaining partners continue, and the partnership owes the deceased partner's estate the value of the dissociated interest, determined and paid according to the partnership agreement or, absent one, the statute's buyout provisions.

The practical work in a partnership estate is usually: locate the partnership agreement, determine the buyout formula and timeline, verify the capital account balance against the last K-1, and make sure the estate is paid what it is owed rather than quietly written off.

One additional exposure worth noting: a general partner's estate may remain responsible for partnership obligations that arose before the death. Confirm what the agreement and state law say before the estate distributes anything.

S Corporations and C Corporations

Corporate stock is the most straightforward of the four, because stock is just property. It passes under the will, or by intestacy, or by a transfer-on-death registration if one was in place -- the same as any other security. The entity itself is unaffected by a shareholder's death.

The complication with an S corporation is not ownership, it is eligibility. An S corporation has a limited list of permitted shareholders, and putting the stock in the wrong hands terminates the S election, which converts the company to C corporation taxation -- a costly and difficult thing to undo.

The good news for executors: Internal Revenue Code section 1361(b)(1)(B) prohibits an S corporation from having as a shareholder a person "other than an estate, a trust described in subsection (c)(2), or an organization described in subsection (c)(6)" who is not an individual. An estate is expressly permitted. The estate can hold the stock through administration without endangering the election.

The trap is what happens after. Under section 1361(c)(2)(A)(iii), a trust that receives S corporation stock pursuant to a will may be a shareholder "only for the 2-year period beginning on the day on which such stock is transferred to it." If the will leaves the stock to a trust -- a very common arrangement -- that trust has to qualify on its own footing before the two years expire, typically by electing to be treated as a Qualified Subchapter S Trust or an Electing Small Business Trust. Missing it can terminate the election retroactively.

Two other corporate items to check early:

Shareholder agreements. Closely held corporations frequently have buy-sell provisions embedded in a shareholders' agreement rather than a standalone document.
Whether the deceased was the only officer and director. If so, the corporation may have nobody with authority to sign anything -- including checks -- until the stock is voted to elect a new board. That is a governance problem to solve in days, not months.

Buy-Sell Agreements: Look Before You Value Anything

A buy-sell agreement is a contract among owners that sets what happens to an ownership interest on a triggering event, most commonly death. It typically specifies who may or must buy, how the price is set, and how the purchase is funded.

If one exists, it usually controls, and it can produce a result that surprises the family: the interest is sold to the surviving owners at a contract price, and what the beneficiaries inherit is the money, not the business.

Find out before anyone spends money on a valuation or makes promises to heirs. The agreement is usually with the corporate records, the company's attorney, or the surviving owners.

Look also for life insurance owned by the business or by a co-owner. Buy-sell agreements are commonly funded with insurance on each owner's life, and those policies do not look like family insurance -- the beneficiary is the company or another owner, not a spouse. They are easy to miss and they are frequently the mechanism by which the estate actually gets paid. Add them to the estate inventory as a distinct line.

The First Two Weeks

Before entity analysis is finished, some things need attention immediately.

Find out who already has authority. Check the business bank signature card, the operating agreement's successor manager provision, and whether anyone holds a corporate office. Someone with existing authority can keep operations running while probate proceeds.
Secure the digital side. Accounting software, payroll provider, business email, point-of-sale, domain registrar, merchant processor. If the only credentials died with the owner, recovery takes weeks and some of it does not recover at all. A password manager, if one exists, is the highest-value thing to find in the first week.
Protect the insurance. General liability, workers' compensation, commercial auto, and property coverage all need to stay in force. A lapse during the estate period is an exposure nobody wants to explain later.
Talk to key employees and customers quickly. Silence is what loses a going concern. A short, honest message that operations continue while arrangements are made is usually enough to hold both groups.
Do not commingle. Business money stays in business accounts. Estate money stays in the estate account. Every transfer between them gets documented. This is the single most common source of trouble in the final accounting.
Log business obligations you pay personally. If you front a payroll run or an insurance premium, record the date, amount, and purpose immediately.
Update the IRS responsible party. Form 8822-B is used to report a change in the responsible party for an EIN, and the IRS requires changes in responsible parties to be reported within 60 days (IRS, About Form 8822-B).

Valuation and Taxes

A closely held business interest is one of the harder things in an estate to value, and one of the few where a professional appraisal is usually not optional. The valuation drives the estate's inventory, the basis the heirs take, any estate tax return, and -- if there are multiple beneficiaries -- what "equal shares" actually means.

Expect a qualified business valuation rather than a rule of thumb, especially where a minority interest or a lack of marketability is involved. Those discounts are real and they are contested territory; a number that is defensible matters.

On the tax side, keep three filings distinct:

The deceased's final Form 1040, covering January 1 through the date of death, including a final Schedule C for a sole proprietorship or the K-1 income allocated to the pre-death period.
The entity's own return -- Form 1065 or 1120-S -- which continues as long as the entity does, with the K-1 split between the decedent and the estate for the year of death.
The estate's Form 1041, reporting income the estate receives after death, including distributions from the business. See IRS Form 1041 for estates.

Business income after death is one of the more common places where an estate's income tax return becomes non-trivial. If the estate is operating a business, a CPA is worth the fee.

Common Mistakes

Assuming the will controls the business interest. An operating agreement, shareholders' agreement, or buy-sell agreement usually comes first. Read those before telling anyone what they are inheriting.

Missing the single-member LLC window. Covered above; it is the deadline most likely to pass unnoticed because nothing visible happens when it does.

Letting the S election lapse. The estate is fine. A testamentary trust holding the stock past two years without qualifying is not.

Operating the business for months without deciding. Drift is a decision, and it is usually the expensive one. Set a date by which the estate will sell, transfer, or wind down, and work backward from it.

Commingling accounts. It creates accounting problems, and in a contested estate it creates credibility problems.

Reusing the deceased's sole-proprietor EIN. For a sole proprietorship being operated by the estate, the IRS requires a new one.

Ignoring personal guarantees. Small business loans, leases, and lines of credit are frequently personally guaranteed by the owner. Those guarantees are claims against the estate, and they need to be identified before anything is distributed.

A Working Checklist

Identify the entity type from tax returns and the Secretary of State's business search.
Confirm the state of formation.
Locate the operating agreement, bylaws, partnership agreement, and any buy-sell agreement.
If it is a single-member LLC, calendar the continuation deadline from the date of death today.
Determine who currently has authority to act -- bank signatory, successor manager, remaining officer.
Secure credentials, accounting software, payroll, and the domain.
Confirm all business insurance is in force and premiums are being paid.
Notify employees, key customers, and vendors that operations continue while arrangements are made.
Obtain certified letters and provide them to the bank, the payroll provider, and the CPA.
Get a new EIN if the estate will operate a sole proprietorship; file Form 8822-B for an existing entity within 60 days.
Search for business-owned or co-owner-owned life insurance policies.
Order a qualified valuation of the interest.
Identify personal guarantees and other business debts that reach the estate.
Decide -- with a date attached -- whether the business will be sold, transferred, or wound down.
Record the interest and its valuation on the estate inventory, and keep business and estate money strictly separate.

Where Professional Help Earns Its Cost

Most of probate can be handled by an organized executor. A business interest is one of the genuine exceptions, and it is worth saying plainly rather than implying otherwise.

An attorney is useful where entity documents conflict with the will, where a buy-sell agreement has to be enforced or interpreted, where co-owners disagree, or where a single-member LLC's continuation has to be documented correctly. A CPA is useful anywhere the S election, multi-entity returns, or basis are in play. Getting a few hours of either is not a failure of self-sufficiency -- it is a normal cost of an unusual asset, and knowing where the line falls is part of making an informed decision about how to run the estate.

What you can do yourself is everything around it: the identification, the document hunt, the deadline tracking, the inventory, the communication, and the record-keeping. That is most of the work, and it is the part that determines whether the professional hours are spent efficiently or spent reconstructing what happened.

How SwiftProbate Helps

SwiftProbate is probate task management software. It helps you understand what needs to happen in an estate, organize documents and assets in one place, and track what is done and what is still open.

A business interest is a good example of why that structure matters. It is not one task -- it is a dependent chain of them, several with hard dates: identify the entity, find the agreements, calendar the continuation window, secure authority, insure, value, decide, report. SwiftProbate keeps the entity documents and certified letters where you can reach them, tracks the business as its own asset with its valuation and supporting documents attached, and holds the deadlines as tasks rather than as something you are trying to remember while also handling everything else.

If you are earlier in the process, the step-by-step probate checklist lays out the overall sequence, and the estate inventory checklist covers how a business interest fits alongside the rest of the estate's assets.

SwiftProbate provides software to help navigate the probate process. SwiftProbate is not a law firm, does not provide legal advice, and is not a substitute for the advice of a licensed attorney. No attorney-client relationship is created by using this service. Probate laws vary by state and county.
