What happens to a sole proprietorship when the owner dies

What happens to a sole proprietorship when the owner dies: the business ends, assets pass to the estate, the EIN cannot be inherited, and licences cancel.

A sole proprietorship does not outlive its owner. Because the business has no existence apart from you, the owner, there is no company for anyone to inherit — only assets, and those assets pass into the estate while the EIN, the licences and the DBA stay behind. An heir or an estate that keeps the work going has to apply for a new EIN in its own name and re-register the trade from scratch.

The Census Bureau counted 29.8 million US businesses with no paid employees in 2022, a count that climbed another 2.1% in 2023 and grew an average 2.7% a year from 2012 to 2023 against 1.1% for employer businesses. Almost all of them are the structure in question: the Bureau notes that the majority of nonemployers are self-employed individuals operating unincorporated businesses (known as sole proprietorships). Two readers usually arrive here — an owner deciding how to hand the work over, and a spouse or executor who needs to know what they are allowed to touch this week.

Does the business itself survive when the owner goes silent?#

No. A sole proprietorship is someone who owns an unincorporated business by themselves, with no separate legal entity behind it. The SBA says the same in structural terms: sole proprietorships do not produce a separate business entity, which means your business assets and liabilities are not separate from your personal ones.

So there is nothing to keep alive. What remains is a pile of property — a van, a laptop, inventory, a customer list, unpaid invoices — plus obligations. An estate is a legal entity created as the result of a person's death that pays any debts owed by the decedent and then distributes the balance to the beneficiaries. That is a wind-down machine, not a business. The fiduciary's primary duties are to collect all the decedent's assets, pay the creditors, and distribute the remaining assets — running a going concern is not on the list.

The UK reaches the identical result by a different route. HMRC's manual states flatly that normally a trade ceases when the sole proprietor dies, because personal representatives are restricted to winding up the affairs of the deceased.

Can anyone inherit a sole proprietorship, or only its assets?#

Only the assets, and they arrive with different tax treatment depending on what they are.

Equipment, vehicles and inventory generally get a fresh start: property acquired from a decedent takes a basis equal to the fair market value of the property at the date of the decedent's death. Uncollected invoices do not. Section 1014(c) says the step-up shall not apply to property which constitutes a right to receive an item of income in respect of a decedent, so a cash-basis proprietor's receivables stay fully taxable when they land.

Client contracts are a third category, and a messier one than most summaries admit. Contractual duties do not automatically die with the person: an executor can be expected to satisfy them out of estate assets, which is why the ABA's Burying Contracts of the Dead advises executors to seek probate court guidance rather than guess, since they can be second-guessed either way. The countervailing rule is personal services. Under the Restatement (Second) of Contracts § 262, if the existence of a particular person is necessary for the performance of a duty, his death or such incapacity as makes performance impracticable is an event whose non-occurrence was a basic assumption of the contract — which discharges the duty. For a one-person design studio or consultancy, that is most of the book of business.

Does the EIN transfer to the heir or the estate?#

It does not, and this is the single most-missed step. IRS Publication 5845 states that a sole proprietor will be required to obtain a new EIN if you purchase or inherit an existing business that you operate as a sole proprietorship. The same publication requires a new EIN where you represent an estate that operates a business after the owner's death.

The logic is that an EIN follows a taxpayer, not a business. That is why the same owner needs no new EIN merely to change the name of your business, change your location or add locations, or operate multiple businesses, and why Publication 15 tells a successor employer that if you took over another employer's business, don't use that employer's EIN. Married couples running a qualified joint venture see the same principle: they submit separate Forms SS-4 as sole proprietors rather than one joint number.

For the estate's own EIN, the SS-4 is filled in a particular way: line 9a is checked "Estate" with the decedent's SSN, line 1 is the decedent's name followed by "Estate," and line 6 is the county and state where the will is probated. If the estate will keep staff on, line 15 asks the date the business began or will begin to pay wages, and line 14 covers the annual Form 944 election where employment tax liability is expected to be $1,000 or less in a full calendar year. Changing the executor or the beneficiaries, by contrast, does not require a new number.

How long can an executor keep the business trading?#

Less time than most families assume, and the leash is statutory. In California, a personal representative may continue operating the decedent's unincorporated business with or without court authorization but may not do so for a period of more than six months from the date letters are first issued unless a court order has been obtained. The statute defines the decedent's business broadly, as an unincorporated business or venture in which the decedent was engaged, and lets any interested person petition the court to direct the representative to discontinue it.

Other states word it differently, but the shape holds: short authority, reviewable by a court, aimed at preserving value rather than growing it.

What are the actual deadlines, from day one?#

This is the calendar that decides what a family can do and when. The California rows are one state's version of a pattern most states share — check your own state's probate code before you rely on a date.

Clock	Length	Source
Small-estate affidavit wait (personal property only)	40 days after death, up to a statutory value cap that is revised periodically	Cal. Prob. Code § 13100
Contractor licence continuance application (CA)	Submit no later than 90 days; Registrar may grant up to one year	CSLB
DBA statement validity after the facts change	Expires 40 days after the change; five years from filing otherwise	Cal. B&P Code § 17920
Creditor claim deadline	Later of four months after letters issue, or 60 days after notice to that creditor	Cal. Prob. Code § 9100
Executor running the business without a court order	Six months from first letters	Cal. Prob. Code § 9760
Petition for final distribution or status report	One year after letters; 18 months if a federal estate tax return is required	Cal. Prob. Code § 12200
Final Form 1040	Generally April 15 following the year of death	IRS Pub. 559
Form 1041, if the estate has more than $600 gross income	April 15 for a calendar-year estate; automatic 5½-month extension on Form 7004	IRS, Form 7004 instructions
Employment tax records retention	At least four years	IRS
UK VAT deregistration	Within 30 days of ceasing to be eligible, or you might be charged a penalty	GOV.UK

Read the middle rows together and the squeeze is obvious. The creditor window alone sets a floor of about four months on probate, while the licence and the DBA can lapse inside 40 to 90 days. The paperwork that keeps trading legal expires before the estate that owns the trade is settled.

Are the spouse and heirs personally liable for the business debts?#

Usually not personally, but the estate absorbs them first. The CFPB states that you are generally not responsible for someone else's debt, and that a debt that needs paying should be paid from the money or property left behind under state law. If there is no money or property left in an estate, or the estate can't pay, then the debt generally goes unpaid — with real exceptions for co-signers, joint account holders, people in community property states, and those in states with necessaries statutes.

The sole-proprietor twist is where the debt reaches. Publication 1635 warns that the business's liabilities are your personal liabilities and you undertake the risks of the business for all assets owned, whether or not used in the business, and the IRS repeats that because the business and owner are not separate, the owner is personally responsible for the business's debts and obligations. A supplier invoice is not ring-fenced to the van and the laptop; it is a claim against everything in the estate.

If collectors call, note that the FTC's policy statement on decedents' debts limits whom a collector may contact — broadly, those authorised to pay debts out of the estate — and bars misleading relatives into believing they are personally liable for a deceased consumer's debts.

Can a spouse take over and keep trading?#

A spouse can start the same work, but they start it as a new business. HMRC spells this out: where a business passes on death from a husband, wife or civil partner to the survivor, the cessation and commencement provisions will apply. One trade ends, another begins.

In the US the practical version is the same list of new registrations: a new EIN, a new licence, a new permit, a new DBA. Where both spouses already worked in the business, the IRS qualified joint venture rules let a married couple treat an unincorporated business as two sole proprietorships where both materially participate, both elect, the couple files a joint return, and the business isn't held in the name of a state law entity — each reporting a share on their own Schedule C and paying self-employment tax on it. That does not make the business survivable, but it does mean the survivor already has their own filing history, their own EIN where one is needed, and a documented role in the work.

What happens to licences, permits and the DBA?#

They are attached to a person, so they end with that person's registration.

California's Contractors State License Board is explicit: if a sole owner dies, the license must be cancelled and a copy of the death certificate sent to CSLB's headquarters. For an individual licence, a member of their immediate family may apply for a continuance; the submission should be no later than 90 days from the date of death, and the Registrar may grant a continuance for up to one year. Corporate licences are ineligible for the plain reason that the entity, not the individual, holds the licence.

Delaware's Division of Revenue puts the general rule in one line: a business license may not be transferred from one owner to another, and new owners must apply for their own.

Sales tax accounts close out too. California's CDTFA requires a seller's permit account to be closed when the holder is no longer actively engaged in business, sells the business or stock of goods, or changes the type or form of ownership — and warns that buyers can be held responsible for a seller's unpaid taxes unless a tax clearance certificate is obtained. As for the trading name, a California fictitious business name statement expires 40 days after any change in the facts set forth in the statement, aside from its five-year term. A DBA does not follow a change in who is doing business.

What happens to unpaid invoices and unfinished work?#

They get collected and taxed, just not by the person who earned them. Income in respect of a decedent is income the decedent was entitled to receive but that was not properly includible in the final income tax return — unpaid wages, business income, installment obligations — and it is taxed to whoever receives it, the estate or the beneficiary (IRS Pub. 559). Section 691(a)(1) requires those items to be included in gross income for the taxable year when received by the estate, by the person who acquires the right by reason of the death, or by the person who acquires it by bequest, devise or inheritance after a distribution.

Combine that with the section 1014(c) carve-out above and the result is worth planning around: the equipment is revalued, the receivables are not. Chase the invoices anyway — an uncollected receivable produces no income for anyone, but it is also value the family never sees.

UK work in progress has its own rule. On the death of a sole trader, the closing value of stock or work in progress is the lower of cost or net realisable value, while stock passing to executors who continue trading is taken at market value — the figure accepted for Inheritance Tax purposes. Where the trade passes to a surviving spouse or civil partner, capital allowances should be calculated as if the assets had passed at open market value, with the probate figure accepted as that value.

Which returns still have to be filed, and by whom?#

The personal representative — executor, administrator, or whoever is in charge of the decedent's property — files the final Form 1040, generally due on April 15 following the year of death, regardless of when during that year death occurred, and a surviving spouse alone can file the joint return if no personal representative has been appointed before the due date. The final Schedule C rides along with that return.

Where there were employees or contractors, IRS closing-a-business guidance sets the list: file the final Form 941 or 944 and check the box to tell the IRS your business has closed and enter the date final wages were paid, file a final Form 940, issue W-2s with Form W-3, and file Forms 1099-NEC with Form 1096 for contractors paid $600 or more. The EIN itself is never cancelled — once assigned it is that entity's permanent federal taxpayer ID, and the IRS can't cancel it, but can deactivate it. To close the business account, send the IRS a letter with the complete legal name of the business, the EIN, the business address and the reason for closing, and keep all records of employment taxes for at least four years.

The estate files its own Form 1041 if it generates more than $600 in annual gross income, and must have its EIN before filing. Two small forms smooth the rest: Form 56, Notice Concerning Fiduciary Relationship, and Form 1310, Statement of Person Claiming Refund Due a Deceased Taxpayer, both listed on the IRS's deceased person page.

Who can actually get into the email, files and client accounts?#

This is where a tidy legal plan meets a locked door. The Stored Communications Act bars a public provider from knowingly divulging the contents of a communication while in electronic storage, permitting disclosure only with the lawful consent of the originator or an addressee or intended recipient of such communication, or the subscriber in the case of remote computing service.

Massachusetts' high court read that consent provision in the executor's favour. In Ajemian v. Yahoo!, Inc., 478 Mass. 169 (2017), the court held the SCA does not prohibit Yahoo from disclosing a decedent's email contents to the personal representatives, because they may lawfully consent on the decedent's behalf — while noting the Act permits disclosure rather than compelling it. Permission is not a key.

State fiduciary-access law adds paperwork rather than leverage. Under RUFADAA as enacted in Minnesota, a custodian discloses a deceased user's content only if a deceased user consented or a court directs disclosure, and the representative must supply a written request, a certified copy of the death certificate, a certified copy of the letter of appointment or equivalent, and evidence of the user's consent such as a will, trust or power of attorney. Delaware's statute reaches the catalogue of communications but releases content only if the custodian is permitted to disclose the content under the Electronic Communications Privacy Act.

The platforms then apply their own filter. Google says it cannot provide passwords or other login details, will decide only after a careful review, and — the detail that catches families out — once the account is closed it is unable to process any request to turn over the contents at a later date. Apple's Digital Legacy route works on an access key plus a death certificate; without a Legacy Contact named in advance, US requesters generally need a court order.

Read together: consent recorded in advance is fast, and a court order obtained afterwards is slow. Meanwhile the client files, the invoicing tool and the domain registrar sit behind a login nobody has.

What happens when a UK sole trader's business goes silent?#

The trade ends, as BIM80570 states, but VAT can be carried across. HMRC's registration manual says that on the death of a sole proprietor the executor or the administrator carries on the business of the deceased and will be registered as the taxable person, which may mean deregistration followed by re-registration, or the executor signing a VAT 68 in favour of whoever now carries on the business. That treatment applies where it is clear that the business will be transferred to the beneficiary, or sold on as a going concern, in the near future, and HMRC makes enquiries if the estate is still unsettled after 12 months. If nothing is being carried on, cancel instead: GOV.UK says you must cancel within 30 days if you stop being eligible or you might be charged a penalty.

Everything else waits on the grant. Personal representatives have absolute control over the assets during the administration period, which starts at the date of death and ends for tax purposes when the residue of the estate is ascertained, and GOV.UK tells executors plainly: you should not make any financial plans or put property on the market until you've got probate. That sentence is why a going concern freezes.

How do a sole proprietorship, a single-member LLC and a corporation compare?#

At the owner's death	Sole proprietorship	Single-member LLC	Corporation
Does the entity survive?	No — it has no existence apart from the owner	Only if someone acts in time: Delaware requires the last member's personal representative to agree to continue within 90 days or such other period as is provided for in the limited liability company agreement	Yes — corporations have a completely independent life separate from its shareholders
Default if nobody acts	Assets fall into the estate; trade ceases	Dissolution on the passage of 90 consecutive days during which the company has no members, the RULLCA rule as enacted in states such as Utah	Shares transfer; the company can continue doing business relatively undisturbed
What heirs receive	Assets only, no business	A membership interest, subject to the continuation rules	Shares
EIN	New EIN required for the heir and for an estate that operates a business after the owner's death	Owner may use their own EIN unless employment or excise returns are due, since an LLC owned by one individual is automatically treated as a sole proprietorship	Held by the corporation
Debts	Personal liabilities of the owner, reaching all assets	Entity's, though some states may require the LLC to be dissolved and re-formed when a member joins or leaves without an agreement in place	Entity's
Licences	Cancelled; a continuance is the exception, not the rule	Held by the entity	Held by the entity — CSLB corporate licences are ineligible for a continuance

If the middle column is where you want to be, the operating agreement is the whole game — see what happens to a single-member LLC and the 90-day dissolution clock for how those windows run state by state.

What should a sole proprietor set up now?#

A short checklist, in the order that removes the most damage:

Write down what stops. Name the licence numbers, the permit accounts, the DBA filing date and the renewal dates. The 40-day DBA expiry and the 90-day CSLB continuance window are the first two things a family will miss.
Decide who applies for the new EIN, and tell them. If the estate will keep the work going, that number has to be applied for before the first Form 1041 is filed.
List the receivables separately. They get no step-up, and an executor who does not know they exist will not chase them.
Record consent for account access in writing — in the will, trust or power of attorney — because RUFADAA custodians release content only on the user's consent or a court order.
Turn on the platform tools that already exist, such as an Apple Legacy Contact, so the fast path is in place before the slow one is needed.
Consider whether the work belongs in an entity. A corporation keeps trading through a change of hands; a sole proprietorship never does.
Keep the instructions where a successor can reach them — the client list, where the keys live, which invoices are outstanding, who to call first.

That last item is the one no legal document handles. It is what Proceedly is for: a business-continuity check-in, and if you miss it past a grace window, a person you name confirms — or, on a paid plan, it releases automatically — before your encrypted handoff plan reaches the people who depend on you. It holds your instructions and where the keys live, never the passwords themselves.

FAQ: what else do owners and executors ask?#

Does a sole proprietorship go through probate? Its assets do, because the business itself is not separate property. Probate has a floor set by the creditor window — in California, a claim is due by the later of four months after letters issue or 60 days after notice to that creditor — and the representative must petition for final distribution or report status within one year of letters, or 18 months if a federal estate tax return is required. Small estates can skip it: California allows a personal-property affidavit once at least 40 days have passed since the death, up to a value cap that is revised periodically, and never for real property.

Can my heir keep using my EIN? No. Publication 5845 requires a new EIN where you purchase or inherit an existing business that you operate as a sole proprietorship, and separately where you represent an estate that operates a business after the owner's death.

What happens if there is no will? The court appoints someone to fill the role rather than the will naming them, and the job is unchanged: collect the property, pay the bills, and distribute what remains to those legally entitled to it — see the California courts' probate self-help guide. The gap that matters is account access — RUFADAA custodians want a copy of the user's will, trust, power of attorney, or other record evidencing the user's consent, and intestacy leaves none.

Are my employees' final wages my family's problem? They are the estate's, and the filings are specific: a final Form 941 or 944 with the box checked to tell the IRS your business has closed and the date final wages were paid, a final Form 940, W-2s with Form W-3, and 1099-NECs for contractors paid $600 or more. If the estate keeps staff on, it becomes an employer itself and enters the date it will begin to pay wages on the SS-4.

Will my clients' contracts transfer to whoever takes over? Some will, some are discharged, and the line is not always crisp. Contractual duties can survive and be satisfied out of estate assets — the ABA's Burying Contracts of the Dead urges executors to ask the probate court rather than guess — but where a particular person's existence is necessary to performance, death or incapacity that makes performance impracticable discharges the duty. Most one-person service work falls on the second side of that line.

How much detail is on record about businesses like mine? The IRS publishes nonfarm sole proprietorship statistics through tax year 2023, covering business receipts, selected deductions, payroll and net income from Schedule C, and the Census Bureau counts nonemployers as businesses with receipts of $1,000 or more ($1 or more for the Construction sector).
