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.
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.
