The first tax notice usually arrives for something nobody knew was due. Not the federal return, which founders expect, but a Delaware franchise tax bill computed a way that produces a five-figure number, or a state registration in a state where one employee happens to live. The pattern is consistent: the obligations are not complicated, they are simply invisible until they are late.
Startups juggle a stack of tax deadlines: federal income tax (Form 1120), state, Delaware franchise tax, payroll (Form 941), and contractor 1099s. Missing one means IRS or state penalties. You automate it by handing tax to a service that files on a managed calendar and flags what is due before it is late. The trap most founders miss is that even a pre-revenue C-corp must file Form 1120 and pay Delaware franchise tax.
The deadline stack most founders miss
| Obligation | Who owes it | When |
|---|---|---|
| Delaware franchise tax + annual report | Every Delaware corporation, revenue or not | March 1 |
| Form 1120, federal income tax | Every domestic C-corp, revenue or not | 15th day of the 4th month after year end |
| Form 1099-NEC to contractors and the IRS | Anyone paying contractors above the threshold | January 31 |
| Form 941, payroll | Anyone running payroll | Quarterly |
| State income or franchise tax | Wherever you have nexus | Varies; California carries an $800 minimum |
Nexus is the one that surprises people. Hiring a single remote employee in another state can create a filing obligation there, and the obligation starts with the hire rather than with revenue in that state.
Why they slip, and what it costs
Founders assume no revenue means no filing. It does not. The Instructions for Form 1120 are explicit that all domestic corporations must file whether or not they have taxable income. A missed Form 1120 or Delaware filing triggers penalties and interest, and a lapsed Delaware good standing can block your next raise at precisely the moment you need a clean certificate.
The penalties are also structured in a way that defeats the intuition that zero revenue means zero exposure. A federal failure-to-file penalty is calculated on tax due, so it is often small at zero tax. But Delaware's penalty is a flat $200 plus interest regardless of revenue, the assessment window under IRC Sec. 6501 never starts if you never file, and the R&D payroll election is lost entirely if the return is not timely.
The Delaware trap worth ten minutes of your time
Delaware offers two ways to compute franchise tax, and the default one is punishing for startups. The Authorized Shares Method charges on the number of shares you authorised, which for a company that authorised ten million shares at incorporation can produce a bill in the tens of thousands.
The Assumed Par Value Capital Method charges on issued shares and gross assets instead, and for a company with modest assets and many authorised shares it is almost always dramatically lower. The minimums are $175 under the Authorized Shares Method and $400 under the Assumed Par Value Capital Method, plus a $50 annual report fee for non-exempt domestic corporations. Delaware sends the bill computed the expensive way; recalculating under the other method is your job, not theirs.
One 2026 change worth noting
The contractor-reporting threshold rose. For payments made after December 31, 2025, a Form 1099-NEC (and 1099-MISC) is required at $2,000, up from the long-standing $600, and the $2,000 figure is inflation-indexed going forward. It is due to the recipient and the IRS by January 31, and filing ten or more information returns in aggregate triggers a mandatory e-filing requirement. The widely cited $600 number is now out of date for these payments, which is worth checking before you rely on last year's process.
What automating this actually means
Software can remind you of a date. What founders need is narrower and more useful than a calendar: someone who knows which obligations you have, prepares the filing, submits it, and confirms it landed.
- A register of every obligation. Every obligation you actually have, including the states you acquired by hiring rather than by selling.
- Filings built on closed books. Prepared from closed books rather than reconstructed at year end.
- Confirmation that each return was accepted, not just submitted.
- A check on the Delaware calculation method every year, because the right answer changes as your share count and assets change.
- The R&D credit captured on the same return rather than missed, since the payroll election cannot be made late.
The week you hire in a new state
Nexus by hiring is named above as the obligation that surprises people most. It is also the one with a clean operational answer, because the trigger is an event you control and can see coming. This is the sequence to run when an offer is accepted, ideally before the start date rather than after the first payroll.
- Flag it at offer stage, not at onboarding. The person who needs to know is whoever handles your payroll and tax registrations, and they need weeks rather than days. State agencies set the timeline, and no amount of urgency on your side changes it.
- Establish which registrations that state requires. Typically employer withholding and unemployment insurance accounts, and in some states additional local obligations. Your payroll provider can usually tell you what applies; the obligation itself remains yours.
- Register before the first payroll if at all possible. Running payroll in a state before the accounts exist creates a cleanup exercise rather than a filing, and the cleanup is more work than the registration would have been.
- Add the new state to your obligations register with its own filing calendar. Its deadlines will not match your existing ones, and a new state that never gets added to the register is a missed filing waiting for a year to pass.
- Check whether anything beyond payroll is triggered. Employing someone in a state can raise questions about other filings there. This is a question for your accountant with your specific facts, and the right moment to ask is now rather than at year end.
The register in step four is the part that persists. Companies that handle their first out-of-state hire well and their fourth badly usually did the registrations correctly every time and never built the list, so by the fourth state nobody can say with confidence what is due where.
Confirming a filing actually landed
Submitted and accepted are different states, and the gap between them is where a surprising number of penalty notices originate. Filed is not a status you should take on trust from anyone, including a provider you are happy with.
- Keep the acceptance confirmation, not the submission receipt. Electronic filings produce an acknowledgement when accepted. A rejected return that nobody re-filed looks identical to a filed one from the outside, until a notice arrives.
- Check Delaware good standing directly. Delaware's status is publicly checkable, and it is worth confirming yourself once a year rather than assuming. A lapse is most often discovered during a raise, which is the worst moment to find out.
- Keep copies of every return filed on your behalf. You need prior-year returns to prepare the current one and to answer any notice. A provider relationship ending should never mean losing access to your own filing history. This is the same argument made at length in do you actually own your books.
- Reconcile what was filed against what you expected. If your register says five filings were due this quarter, confirm five acknowledgements exist. This takes minutes and is the only check that catches the obligation nobody knew about.
If you change tax preparers or bookkeeping providers mid-year, get written confirmation of exactly which filings each side is handling for the transition period. Returns straddling a provider change are among the most common filings to be missed entirely, because both sides can reasonably assume the other has it. The switching mechanics are covered in how to switch bookkeeping providers.
How Zinance runs the calendar
Tax and compliance sit inside your finance function on a managed calendar covering federal, state, and Delaware, with a human who files and confirms, so nothing depends on you remembering a date. Because your books close daily, filings are built on current numbers rather than a year-end scramble, and the R&D credit is captured along the way instead of missed.
This article is educational and general, not tax, legal, or accounting advice, and it creates no client relationship. Filing obligations depend on your entity, states, and tax year, and the rules change. Confirm your own deadlines with a qualified tax professional.
Two of these deadlines carry more money than the rest. The Delaware calculation method is worth checking every year, covered in why your Delaware franchise tax is so high, and the R&D payroll election cannot be made late, covered in the R&D tax credit for startups.
