The first invoice the company ever received was from the registered agent. It was for a small amount, it arrived by email with no covering note, and it was addressed to an entity that had no product, no customers, no bank account and no revenue. We had been a company for eleven days.
I remember looking at it and thinking that it was a rounding error, which it was, and then thinking that it would arrive again next year and the year after that whether or not anything else went well. Which it will.
That invoice is the beginning of a category of spending most founders never model: what it costs simply to exist. Not to build anything. Not to serve anyone. Just to remain a company in good standing that has not been administratively dissolved.
The standing costs
There are five of them and they are all boring, which is why they get missed.
The registered agent. Every US entity needs a registered agent with a physical address in the state of formation, available during business hours to receive legal service. If you have no US address you cannot be your own. This is an annual fee and it is the one bill that arrives whether or not you do anything.
Franchise tax. For a Delaware LLC this is a flat annual amount due on 1 June, which is refreshingly simple. For a Delaware corporation it is not simple, and this is where founders get their first genuinely alarming letter. There are two calculation methods. The default one is based on authorized shares, and a company that has authorized ten million shares receives a number that looks like a mistake. The second method takes account of issued shares and gross assets and typically produces something far smaller for an early-stage company. Both are legitimate. You pay the lower one. Nobody tells you this in advance.
The employer identification number. Free to obtain, but if no founder has a US social security number you cannot use the online process. You file the application by fax or mail and you wait, sometimes for several weeks. Nothing else can proceed without it, so this is the item that should be started on day one rather than day forty.
A bank account. This is consistently the hardest step for a founding team based outside the United States, and it is the one that blocks everything else. You will need the formation documents, the employer identification number, identification for the beneficial owners, and usually a plausible answer about what the business does and where its customers are. Budget months, not weeks. Plan around it rather than assuming it.
Accounting and tax preparation. A US entity files a return whether or not it earned anything. Zero revenue does not mean zero filings, and a preparer who understands foreign-owned entities is not the cheapest one available.
The filings that carry real penalties
Most of the annual obligations are small in money and irritating in effort. Two are neither.
The first is the information return required of a foreign-owned single-member LLC, filed alongside a pro forma corporate return. It reports transactions between the entity and its foreign owner. It is not a tax calculation and often results in no tax at all. The penalty for not filing it is twenty-five thousand dollars. That number is not a typo and it is not scaled to the size of the company. Founders who form an LLC precisely because it seemed like the light option are the ones most likely to be unaware this exists.
The second is the corporate income tax return itself, which is due regardless of activity. A dormant company still files. Filing late compounds, and the first year of a startup is exactly when nobody is watching a calendar.
Then there are the deadlines, which do not move for you. Delaware corporations file their annual report and franchise tax by 1 March. Delaware LLCs pay by 1 June. If you have registered as a foreign entity in another state because that is where you actually operate, that state has its own report, its own fee and its own date. Put every one of them in a shared calendar with a reminder two weeks ahead, because the person who remembers in year one will be busy in year two.
Three layers of cost, and why you should separate them
The useful move here is to stop treating spending as one number and split it into three, because they start at different moments and behave differently under growth.
Cost to exist. Registered agent, franchise tax, accounting, filings. Fixed, annual, unavoidable, starts on the day you file. It does not care about revenue and it does not scale with users. For a lean single-entity structure this lands in the low four figures a year, more if you have qualified in a second state or your ownership structure needs specialist tax work. Write the real number down. It is the amount you must be able to cover in a year where nothing happens.
Cost to operate. Domain, email, code hosting, error monitoring, the design tool, the thing that sends transactional email. Starts when you begin building and grows with the team rather than with the customers. Most founders track this one because the bills are monthly and visible.
Cost to serve. Inference, storage, egress, anything metered per request. Starts when someone uses the product and scales with success rather than with headcount. This is the layer that makes an AI company different from a software company, and it is the subject of Lesson 7. For now the only thing that matters is that it is a separate line, because if you blend it into operating cost you will never be able to answer the question of what a customer costs you.
Three layers, three behaviors. The first is a floor. The second is a choice. The third is a consequence.
Three ways this goes wrong
You budget formation as a one-time cost. The filing fee is one-time. Everything else recurs, and it recurs in a year when there is no revenue to absorb it. A company that raised nothing and earned nothing can still be dissolved for not paying a few hundred dollars on time, which is an embarrassing way to lose a name you have been using for eighteen months.
You optimize the wrong end. Founders will spend two weeks comparing formation services to save a hundred and fifty dollars, then miss an information return that carries a twenty-five thousand dollar penalty. The formation is the cheap part. The maintenance is the part with the sharp edges.
You sequence the bank account last. It is the longest lead item and the one you control least. Everything else can be done in an afternoon. If you leave it until you need to receive money, you will be explaining to your first customer why you cannot invoice them yet.
None of this is expensive in absolute terms. That is exactly why it gets ignored. A cost that is small but certain is much easier to plan for than a cost that is large but uncertain, and yet founders reliably do the opposite, modeling the revenue nobody has promised and skipping the invoice that arrives every year without fail.
A company has a heartbeat cost, and it starts on the day you file, not the day you sell.
