Delaware Franchise Tax for Startups: How to File It Yourself in 15 Minutes

This post is general information, not tax advice for your specific entity. The mechanics below apply to typical venture-backed Delaware C-corps; edge cases exist.

Every January, a wave of panic hits founder inboxes. Delaware sends a notice that says you owe something like $85,000 in franchise tax, and within days a dozen service providers offer to “handle it” for you. The number is real. The panic is manufactured. For the vast majority of early-stage startups, the actual Delaware franchise tax bill is a few hundred dollars, and filing it yourself takes about 15 minutes once a year.

This post is the part nobody selling you a filing service wants to explain: why the scary number appears, why it is almost never what you actually owe, and exactly how to file it on your own before the deadline. If your company is pre-seed through Series B and your accounting is in reasonable shape, you do not need to pay anyone to do this.

Why Your Delaware Franchise Tax Notice Shows $85,000

Delaware calculates your franchise tax two different ways and lets you pay the lower of the two. The notice you receive in January defaults to the method that produces the bigger number, because that method is tied to a single piece of data Delaware already has: your authorized shares.

This is the Authorized Shares Method. It ignores your finances entirely and taxes you purely on how many shares your charter authorizes. The brackets are simple: 5,000 authorized shares or fewer is the $175 minimum, 5,001 to 10,000 shares is $250, and every additional 10,000 shares adds $85. Most startups authorize 10,000,000 shares at incorporation so there is room for option pools and future rounds. Run that through the formula and you get a bill of $85,165. That is the number on the scary notice, and it is the reason a whole cottage industry exists to “save” you from it.

How to Calculate Delaware Franchise Tax the Cheaper Way: The Assumed Par Value Method

The second method, the Assumed Par Value Capital Method, accounts for the reality that your 10,000,000 authorized shares are mostly unissued and your company is not actually worth what a naive share count implies. For an early-stage company it almost always produces a tax in the low hundreds of dollars, and Delaware lets you choose it. The January notice just does not advertise it.

This method ties your tax to your gross assets and your issued shares. The minimum is $400, the rate is $400 for every $1,000,000 (or portion of a million) of “assumed par value capital,” and the math runs in three steps. First, divide your total gross assets by your total issued shares to get an assumed par value per share. Second, multiply that assumed par value by your total authorized shares to get your assumed par value capital. Third, divide that figure by $1,000,000, round up to the next whole number, and multiply by $400.

A quick example. Say you have $2,000,000 in gross assets, 8,000,000 issued shares, and 10,000,000 authorized shares. Your assumed par value per share is $2,000,000 divided by 8,000,000, or $0.25. Multiply that by 10,000,000 authorized shares and your assumed par value capital is $2,500,000. Divide by a million, round up to 3, multiply by $400, and your franchise tax is $1,200. Not $85,165. Same company, same year, just the calculation the state did not put in front of you.

The lower your gross assets and the higher your issued share count relative to authorized, the smaller this number gets. A pre-seed company with modest cash in the bank often lands at or near the $400 floor.

What You Need to File: Your Cap Table and Year-End Bank Balance

You do not need an accountant on retainer for this. You need two pieces of information, both of which you should already have.

The first is your capitalization detail: total authorized shares, total issued shares, and par value per share from your certificate of incorporation. Your cap table (Carta, Pulley, or a clean spreadsheet) has all of this. Authorized shares are in your charter; issued shares are the total actually granted to founders, employees, and investors as of the end of the year.

The second is your total gross assets as of December 31. For franchise tax purposes, Delaware uses the total assets figure reported on your federal tax return (Form 1120, Schedule L). If your return is not filed yet, your year-end balance sheet total assets is the working number: cash in the bank plus any other assets on the books as of 12/31. For most early-stage companies this is dominated by cash, so your bank balance as of December 31 is the figure that matters most.

That is it. Cap table and year-end gross assets. With those two inputs you can file.

How to File Delaware Franchise Tax Yourself in 15 Minutes

The entire process happens on Delaware’s own portal. Go to the Delaware Division of Corporations website and open the franchise tax filing system. You will need your seven-digit Delaware file number, which is on the notice the state sent you and on your incorporation documents.

When the system loads, it shows the Authorized Shares calculation first, with the large number. Do not stop there. Enter your issued shares, your total gross assets as of December 31, and your par value, and the system recalculates using the Assumed Par Value Capital Method automatically. It shows you both results and bills you the lower one. You complete the annual report at the same time (the filing fee for a domestic corporation is $50, added to the tax), confirm your registered agent and officer or director information, and pay by card or ACH.

Print or save the confirmation. You are done until next year.

When Is Delaware Franchise Tax Due, and What Happens If You’re Late

Here is the one place where urgency is warranted, and it has nothing to do with hiring anyone. The Delaware franchise tax and annual report are due on or before March 1 each year. Miss it and Delaware adds a $200 penalty plus interest of 1.5% per month on the unpaid tax and penalty. Let it slide for months and your company eventually loses its good standing, which becomes a real problem the moment a term sheet triggers due diligence.

None of that requires a service provider to prevent. It requires a calendar reminder. Set one for mid-February, block 15 minutes, and file. If your tax happens to come out to $5,000 or more (uncommon at early stage, but possible as assets grow), Delaware requires quarterly estimated payments rather than a single March payment, with 40% due June 1, 20% on September 1, 20% on December 1, and the balance by March 1. Your accountant should flag this if it applies, but most seed-stage companies never cross that threshold. The Delaware deadline is also not the only one on your calendar; it sits alongside your California and federal dates, which we lay out in our guide to startup tax deadlines for Delaware and California.

When It Actually Is Worth Handing Off

Filing your own franchise tax makes sense when your cap table is clean, your books are current, and your structure is a single Delaware C-corp. That describes most companies through Series B. The filing is genuinely simple, and paying a premium for 15 minutes of data entry is not a great use of capital you raised to build a product.

It stops being a do-it-yourself job when the inputs get messy: multiple entities or subsidiaries, a recent recapitalization or stock split that complicates the issued-share count, gross assets large enough to trigger quarterly estimates, or books that are not closed and reconciled so you cannot trust your December 31 total assets. At that point the value is not in the filing itself; it is in getting the underlying numbers right so the filing is correct. That is a conversation worth having. The 15-minute version, for a clean early-stage company, is not.

Frequently Asked Questions

How much is the Delaware franchise tax for a startup? For a typical early-stage Delaware C-corp using the Assumed Par Value Capital Method, the tax is usually a few hundred dollars, with a $400 minimum under that method. The much larger figure on your January notice comes from the default Authorized Shares Method, which you are not required to use.

Can I file my Delaware franchise tax myself? Yes. For a single Delaware C-corp with a clean cap table and current books, filing on the state portal takes about 15 minutes. You only need your file number, your authorized and issued shares, your par value, and your total gross assets as of December 31.

When is the Delaware franchise tax due? On or before March 1 each year, filed together with your annual report. Companies owing $5,000 or more pay in quarterly estimated installments instead.

What happens if I miss the deadline? Delaware charges a $200 penalty plus 1.5% interest per month on the unpaid tax and penalty, and prolonged non-payment puts your company’s good standing at risk, which surfaces immediately during investor due diligence.

Why is my Delaware franchise tax bill so high? Because the notice defaults to the Authorized Shares Method, which taxes you on authorized shares alone. Switching to the Assumed Par Value Capital Method on the same filing almost always reduces it dramatically for early-stage companies.

The honest summary: the Delaware franchise tax is one of the most over-sold compliance tasks in the startup world. The number on the notice is designed to alarm you. The actual obligation, for a typical early-stage Delaware C-corp, is a few hundred dollars and a quarter hour of your time, as long as it is done by March 1.
