The short version
- Forming in Delaware does not remove your home state. If the company has an office, employees or repeated in-state business anywhere else, it registers there too — so most Delaware entities run by one or two people pay two states rather than one.
- Qualification turns on presence and repeated intrastate transactions, not on where customers are. California defines transacting intrastate business as "entering into repeated and successive transactions of its business in this state, other than interstate or foreign commerce".
- The usual penalty for skipping registration is procedural, not a fine. Delaware's own statute bars an unqualified foreign corporation from maintaining any action in Delaware until it registers and pays every fee, penalty and franchise tax for the years it went unregistered.
- Delaware law governing your internal affairs is not guaranteed. California Corporations Code § 2115 applies a list of Californian corporate rules to foreign corporations whose business and shareholders are majority Californian, unless the shares are listed on a major exchange.
Two separate filings are involved and they are routinely discussed as one. Formation creates the entity in exactly one state, which becomes its domestic state permanently. Qualification is the permission every other state requires before you carry on business inside its borders — the paperwork that puts a company incorporated elsewhere on a second register as a "foreign" entity. Foreign here means out-of-state, not out-of-country.
Nothing about picking Delaware, Nevada or Wyoming touches the second filing. The formation state is a choice about which body of corporate law governs the owners' relationship with each other. It is not a choice about where you operate, and it cannot be, because you make it before you know.
What "doing business" means, and what it does not
There is no federal definition. Each state writes its own, and most use the same two-part pattern: a broad phrase, then a list of activities that expressly do not count. California is representative. Corporations Code § 191 defines transacting intrastate business as "entering into repeated and successive transactions of its business in this state, other than interstate or foreign commerce", then carves out maintaining or defending a lawsuit, holding board and shareholder meetings, keeping bank accounts, selling through independent contractors, soliciting orders accepted outside the state, and isolated transactions completed within 180 days.
Read the carve-outs and the shape of the test is clear. It is about presence and repetition, not revenue and not where your customers live. A company selling nationally from one office is generally not transacting business in forty-nine states.
Where the qualification line usually falls
Remote sales only
Independent contractors
Repeated in-state deals
Office or payroll
The penalty is procedural, and that is what makes it bite
Most articles describe the consequence as back fees and interest. That understates it. Nearly every state also has a door-closing statute, and Delaware — the state everyone is being pointed towards — states the rule as plainly as anywhere. Under 8 Del. C. § 383, a foreign corporation that has done business in Delaware without authority "shall not maintain any action or special proceeding in this State unless and until such corporation has been authorized to do business in this State and has paid to the State all fees, penalties and franchise taxes for the years or parts thereof during which it did business in this State without authority". California Corporations Code § 17708.07(a) does the same for LLCs. You discover this on the day you try to sue a customer who has not paid, which is the day the defendant's lawyer checks the register.
Be equally clear about what the penalty is not, because the alarm is usually overdone. Failing to qualify does not void your contracts. It does not stop you defending a claim — § 17708.07(b) says so expressly. And it does not strip limited liability: § 17708.07(c) states that a member or manager is not personally liable for the company's debts merely because it operated without registering. The ways owners actually lose that protection are in piercing the corporate veil, and an unfiled registration is not one of them.
What Delaware is actually selling
Delaware's product is predictability. The Court of Chancery hears business disputes without juries and has produced decades of decisions on the same recurring questions, so both sides' lawyers can forecast the outcome. Under the internal affairs doctrine, courts generally apply the law of the state of incorporation to relations between a company, its directors and its shareholders. Combine the two and an investor knows in advance which rules apply to a board fight, and roughly how it ends.
That is a real thing to buy, and worth the money where there are outside investors, independent directors and a plausible governance dispute. It is worth much less when the company is two founders and an accountant. Whether you need a corporation at all, before you need Delaware, is the prior question — LLC vs corporation covers it.
Where you formed against where the work happens
Where you formed
Where the work happens
One state
Several states
Home state
One register
Formation and operations in the same place. One agent, one annual filing, one fee.
Home plus each
Qualify wherever there is an office or a payroll. The formation state is not an extra.
Delaware
Two for one state
Delaware fees and agent, then full qualification at home anyway. The most common version, and the hardest to justify.
Delaware plus each
What investors expect. Delaware is one more line on a bill you were already paying.
The franchise tax that catches new companies
Delaware corporations calculate franchise tax by one of two methods, and the default produces the frightening number. The authorised shares method charges in bands by the number of shares the certificate of incorporation authorises, whether or not a single share has been issued. The assumed par value capital method recalculates from issued shares and total gross assets as reported on the federal return, at a fixed rate per million.
A company that authorised ten million shares because a template suggested it, then issued a few thousand, gets a first bill under the default method that bears no relation to its size — and can usually cut it sharply by recomputing under the second. The state publishes a calculator; rates and the cap move, so take figures from the Division of Corporations, not from an article. The better fix is authorising a sensible number of shares to begin with, a decision recorded in the corporate bylaws and the founding board resolution.
Deadlines then differ by entity and by direction: Delaware domestic corporations file the annual report and pay by 1 March, while foreign corporations registered in Delaware file by 30 June. Missing either adds a penalty plus monthly interest. Two states means two calendars, which is what the deadline tracker is for.
Operating agreement template
Whichever state you form in, the members' relationship is governed by the agreement between them. Ownership, management, transfers and dissolution, with the governing-state clause in the position it normally occupies.
Tax nexus is a different question with different answers
Registering with the Secretary of State is one register. There are at least three more, run by different agencies, triggered by different things, and none of them follows automatically from the others.
| Register | Run by | What puts you on it |
|---|---|---|
| Entity qualification | Secretary of State | Physical presence or repeated intrastate business |
| Income or franchise tax | State revenue department | Nexus tests, often with sales, property and payroll thresholds |
| Sales and use tax | State revenue department | Remote sales above that state's economic-nexus threshold |
| Payroll and unemployment | Labour and revenue agencies | A single employee working in the state |
One federal statute cuts across this, and it is narrower than people assume. Public Law 86-272, at 15 U.S.C. § 381, stops a state taxing the net income of an out-of-state business whose only in-state activity is soliciting orders approved and filled from outside the state. It protects sales of tangible personal property only. A services business, a software subscription or a licensing company gets nothing from it. Sales tax sits outside it altogether: since South Dakota v. Wayfair in 2018, states may require remote sellers to collect on in-state sales volume alone.
Delaware law may not govern your internal affairs anyway
This part rarely appears in the comparison, and it undoes the central promise. California Corporations Code § 2115 reaches into foreign corporations that are Californian in substance. Where the average of a corporation's California property, payroll and sales factors exceeds 50 per cent, and more than half its voting shares are held of record by people with California addresses, California applies its own corporate law to a long list of internal matters: election and removal of directors, directors' duties and liability, cumulative voting, shareholder approval of mergers and asset sales, dissenters' rights, and inspection of records.
Shares listed on a major exchange are excluded, which makes this a private-company problem. The result is that a Delaware corporation with a Los Angeles office and Californian shareholders can find Californian rules applying to the exact questions Delaware was chosen to settle. It is an argument for treating the shareholder agreement and the bylaws as the primary source of governance, rather than expecting a choice of state to do that work.
Who writes the articles you have been reading
Search this question and most of the first page is published by registered-agent and formation companies. They are not lying, but their revenue is a recurring fee per entity per state per year, and the recommendation that maximises it is "form in Delaware, then qualify at home". Read the genre with that in mind, including the parts of it that are correct.
The detail nobody selling the service leads with is that some states add costs falling only on foreign entities. A foreign LLC qualifying in New York must, under § 802 of the Limited Liability Company Law, publish notice once a week for six successive weeks in two newspapers designated by the county clerk, then file the certificate of publication within 120 days — or its authority to do business in the state is suspended until it does.
A short way to decide
Five questions before you file anything
- Will an institutional investor buy equity within about two years? If yes, form a Delaware corporation and stop reading comparisons.
- Where will the office, the payroll and the repeated in-state contracts be? That state gets a filing regardless of where you form.
- How many states is that in year one? Multiply the agent fee and annual report by that number before deciding.
- If you form away from home, who is diarising two annual deadlines?
- Is most of the ownership, and most of the business, in one state? Check whether that state applies its own corporate law to you anyway.
For a business with one office and no outside investors, forming at home is not a compromise. It is the version with fewer moving parts, and nothing Delaware sells would have been used. For a company raising institutional money, Delaware is not really a choice either: the investors bring it with them, and it sits on top of the home-state filing rather than instead of it. What the decision never does is reduce the number of registers you are on — it only decides which one is first. The documents that follow, the operating agreement or the bylaws, do far more to determine how the company is run than the line on the certificate naming a state.

Frequently asked
Do I have to register my LLC in my home state if I formed it in Delaware?
Almost certainly, if the business is genuinely run from there. A Delaware LLC operating out of an office in another state is a foreign LLC in that state and must qualify under its registration statute. The Delaware formation stays in place; the home-state registration is added to it. The result is two registered agents, two annual filings and two sets of fees for one business.
Does having customers in a state mean I am doing business there?
Usually not on its own. Qualification statutes turn on presence and repeated intrastate transactions, and most expressly exclude selling through independent contractors, soliciting orders accepted outside the state, and isolated transactions. A website that ships into a state is rarely enough. Sales tax is a separate question with much lower thresholds, and that one can be triggered by remote sales alone.
What happens if I never register in the state where I actually work?
The common penalty is procedural. Most states have a door-closing statute that bars an unregistered entity from bringing or maintaining a lawsuit there until it registers and pays the fees, penalties and taxes for the years it went unregistered. Contracts stay valid and you can still defend claims against you. The problem surfaces at the worst moment: the day you need to sue someone who owes you money.
Is Delaware worth it if I am not raising venture capital?
Often not. Delaware sells predictable corporate law and a specialist business court, which matters most where there are outside investors and a real prospect of a governance dispute. For a company with two owners and one office, that predictability is bought at the price of a second state's fees, a second registered agent and a second annual filing, and is then never used.
Does forming in Delaware mean Delaware law governs my company?
For internal affairs, generally yes: courts usually apply the law of the state of incorporation to relations between the company, its directors and its shareholders. The exception worth knowing is California's pseudo-foreign corporation statute, which imposes a list of Californian corporate rules on foreign corporations whose business and shareholders are mostly Californian, unless the shares are listed on a major exchange.
