How to Avoid Penalties on Your Delaware Franchise Tax: A Step-by-Step Guide

Delaware calculates franchise tax under the Authorized Shares Method or the Assumed Par Value Capital Method, and you pay the lower amount. The catch: under 8 Del. C. §503(b), if you do not report issued shares and total gross assets when you file, Delaware uses the Authorized Shares Method.

Under the Authorized Shares Method, a startup with 10,000,000 authorized shares owes $250 for the first 10,000 shares plus $85 for each of the other 999 blocks of 10,000, or $85,165. Many founders see that number, assume it is an error and ignore it, which is how penalties start.

Under the Assumed Par Value Capital Method, the same company with 2,000,000 issued shares, $0.00001 par and $500,000 of gross assets has an assumed par of $0.25 and assumed par value capital of $2,500,000. At $400 per million or portion of a million, the tax is $1,200. With fewer assets or more issued shares it drops to the $400 minimum.

The annual report and franchise tax for a domestic Delaware corporation are due by March 1, unrelated to your federal Form 1120 deadline of April 15 (or October 15 on extension for calendar-year corporations). Missing March 1 triggers a one-time $200 penalty plus interest of 1.5% per month on the tax and penalty.

Example: a company owing $400 of franchise tax plus the $50 annual report fee files six months late. The penalty is $200. Interest is roughly $600 × 1.5% × 6 = $54. The bill grows from $450 to about $704.

The bigger risk is losing the charter. Under 8 Del. C. §510, if a corporation goes one year without paying the tax or filing a complete report, its charter becomes void. By November 30 the Secretary of State notifies delinquent corporations that the charter will be void unless they pay and file by the following March 1. Reviving a void charter requires a certificate of revival plus all back taxes, penalties and interest, and while the charter is void the company cannot get a certificate of good standing, which investors and acquirers ask for at closing.

Corporations that expect to owe $5,000 or more must also make estimated payments: 40% by June 1, 20% by September 1, 20% by December 1 and the rest by March 1.

1. Gather the inputs: authorized shares by class (from your charter), issued shares by class (from your cap table as of year end), par value, and total gross assets from your year-end balance sheet, which should match Form 1120, Schedule L.
2. Open the annual report on the Delaware Division of Corporations site using your entity file number.
3. Enter issued shares and gross assets so the Assumed Par Value Capital Method can be applied. Enter each class of stock separately.
4. Enter directors, officers and the principal place of business, then pay online.
5. Save the confirmation and a PDF of the filed report with your corporate records.

We file in January or February so there is time to fix errors before March 1. If your fiscal year is not the calendar year, use gross assets for the fiscal year ending in the calendar year being reported.

The most common mistake is not seeing the notice. Delaware prints franchise tax notices in December and sends them to your registered agent, not to the founders, so a stale agent email address means the notice goes nowhere.

Other mistakes we see regularly:

• Ignoring an $85,165 notice because it looks like a scam, then missing March 1
• Filing the report without gross assets, which defaults the tax to the Authorized Shares Method
• Counting authorized shares as issued shares, or missing a class of preferred stock
• Using a stale gross asset figure after a financing closed in the prior year
• Paying only the tax and forgetting the $50 annual report fee, or the reverse

Each one leads to overpayment, a penalty, or both.

If you paid under the Authorized Shares Method by mistake, you can usually recover most of it with a refund petition filed by March 1 of the second calendar year after the tax year. Here is a hypothetical case.

A startup with 10,000,000 authorized shares files its 2025 annual report in February 2026 without entering gross assets. Delaware calculates the tax under the Authorized Shares Method, and the company pays $85,165 plus the $50 report fee. With 2,000,000 issued shares and $300,000 of gross assets, the Assumed Par Value Capital Method would have produced an assumed par of $0.15, assumed par value capital of $1,500,000 and a tax of $800 (two portions of $1,000,000 at $400 each).

The overpayment is $85,165 minus $800, or $84,365. Under 8 Del. C. §505, the petition for the 2025 tax year must be filed by March 1, 2027. Gather the year-end balance sheet, the cap table showing issued shares and the filed report, then submit the refund request signed by the authorized person on the report.

Miss that date and the money is gone. Put the refund deadline on the same calendar as the next annual report.

A short year-end routine, started in December, prevents almost every Delaware penalty we see.

1. December. Confirm your registered agent's notification email reaches someone who acts on it, and look for the franchise tax notice.
2. Early January. Close the books for December and pull total gross assets from the balance sheet. Make sure any round that closed in the year is recorded.
3. January. Export issued shares by class as of December 31 from the cap table and check them against the charter's authorized shares.
4. Late January or February. Calculate both methods so you know what the state should charge before you open the filing.
5. Before March 1. File the annual report with issued shares and gross assets, list current directors and officers, and pay the tax and $50 fee together.
6. After filing. Save the confirmation, and if you expect $5,000 or more of tax for the current year, diary the June 1, September 1 and December 1 estimated payments.

Interest under 8 Del. C. §504 runs at 1.5% for each month or portion of a month, so a filing one day late in March is charged as a full month.

If you already paid under the Authorized Shares Method, you can ask for a refund. Under 8 Del. C. §505, a corporation can petition for a refund no later than March 1 of the second calendar year after the tax year. Delaware's refund request form is signed by the authorized person listed on the annual report and sent to the Division of Corporations Franchise Tax section.

If you were assessed a penalty because you missed March 1, file and pay as soon as possible, since interest keeps running monthly. If the charter has already become void, plan the revival before your next financing or customer contract, because diligence will catch it.

For our Delaware clients we prepare the annual report from the cap table and year-end balance sheet, file under the Assumed Par Value Capital Method and confirm payment before March 1. This is general information, not tax advice for your specific facts.
