Delaware Assumed Par Value Capital Method Explained

What is the Delaware Assumed Par Value Capital Method?

The Assumed Par Value Capital Method is one of two ways a Delaware corporation may calculate its annual franchise tax. The other is the Authorized Shares Method, which counts only the number of shares your certificate of incorporation authorizes. The Assumed Par Value Method takes a different approach: it looks at how many shares you actually issued and how much your company is worth in gross assets, then derives a tax from those real figures. Delaware lets you compute both and pay whichever is lower, up to a $200,000 maximum for a standard corporation.

This method exists precisely because the Authorized Shares Method punishes a common startup choice — authorizing millions of shares at a tiny par value. A founder who incorporates with ten million authorized shares can receive an Authorized Shares notice in the tens of thousands of dollars, even with no revenue. The Assumed Par Value Method gives that same company a way to pay close to the $400 minimum instead. It is corporation-only: LLCs have no shares or par value, so a Delaware LLC simply pays a flat $300 franchise tax, as our Delaware franchise tax overview explains.

What is the exact formula for the Assumed Par Value Method?

The calculation runs in three steps, and getting each input right is what separates a $400 bill from a much larger one:

• Step 1 — Assumed par per share. Divide your total gross assets (the figure from your federal Form 1120 balance sheet) by your total issued shares. The result is the assumed par value per share.
• Step 2 — Assumed par value capital. Multiply that assumed par per share by your total authorized shares. That product is your assumed par value capital.
• Step 3 — Apply the rate. The tax is $400 for every $1,000,000 (or part thereof) of assumed par value capital, subject to a $400 minimum.

Two rules round out the math. First, the assumed par value used in Step 2 can never be lower than the actual par value stated on your certificate, and Delaware applies a separate floor so the assumed par is at least a minimum amount per share. Second, the final tax is capped at $200,000 for a standard corporation. Because the formula multiplies a small assumed par against your share count, the single biggest lever is gross assets: low assets keep the assumed par tiny, which keeps the whole bill near the floor. You can test the math without doing it by hand on our Delaware franchise tax calculator.

How do I work through a real example?

Consider a startup with 10,000,000 authorized shares, 8,000,000 issued shares, and $500,000 in total gross assets. Step 1: $500,000 ÷ 8,000,000 = $0.0625 assumed par per share. Step 2: $0.0625 × 10,000,000 = $625,000 assumed par value capital. Step 3: $625,000 is less than $1,000,000, so it rounds up to one $1,000,000 block, and the tax is one × $400 = $400. The same corporation under the Authorized Shares Method would owe roughly $85,000 on 10,000,000 authorized shares — a difference of more than $84,000 from choosing the right method.

Now scale the company up. Suppose assets grow to $5,000,000 with the same share counts. Step 1: $5,000,000 ÷ 8,000,000 = $0.625 assumed par. Step 2: $0.625 × 10,000,000 = $6,250,000 assumed par value capital. Step 3: $6,250,000 spans seven $1,000,000 blocks (the partial seventh block rounds up), so the tax is 7 × $400 = $2,800. The pattern is clear: the Assumed Par Value Method scales with how big your company actually is, which is exactly why it feels fair to operators. The figures here are illustrative — always confirm the current rate and your exact numbers on the state portal before you pay.

A third variation is worth seeing because it shows the rounding rule in action. Take a corporation with 15,000,000 authorized shares, 10,000,000 issued shares, and $2,400,000 in gross assets. Step 1: $2,400,000 ÷ 10,000,000 = $0.24 assumed par per share. Step 2: $0.24 × 15,000,000 = $3,600,000 assumed par value capital. Step 3: $3,600,000 spans four $1,000,000 blocks once the partial fourth block rounds up, so the tax is 4 × $400 = $1,600. Notice that every partial million rounds up to a full block — there is no proration within a block — so a company sitting just above a round-million threshold pays the same as one sitting at the top of it. Keeping clean books that pin down gross assets precisely is therefore worth real money, because crossing a single threshold adds $400.

Why do startups use the Assumed Par Value Method?

Most venture-track startups incorporate with a large authorized-share pool — often 10,000,000 shares — so they can issue founder equity, build an option pool, and raise priced rounds without amending the charter every time. That share pool is great for cap-table flexibility but terrible under the Authorized Shares Method, which taxes the raw authorized count. The Assumed Par Value Method is the escape hatch: it ties the tax to issued shares and gross assets, both of which start small.

The result is that a pre-revenue or seed-stage Delaware C-Corp with a few hundred thousand dollars in the bank usually pays the $400 minimum, while the Authorized Shares notice for the same company might read $80,000 or more. That gap is why every experienced startup accountant recalculates before paying. If you are still choosing between entity types and want to avoid share-based math entirely, the flat $300 LLC franchise tax is far simpler to budget — our LLC vs corporation franchise tax comparison lays the two side by side.

Assumed Par Value vs Authorized Shares: which is lower?

Delaware does not force you to pick one method for good. Each year you may compute both and pay the lower amount. The state mails (and the portal pre-fills) the Authorized Shares figure, but that is just the default — not a final bill. Here is how the two methods compare for the same startup profile:

The takeaway: corporations with very few authorized shares (5,000 or fewer) often do best on the Authorized Shares Method at $175, while corporations with large authorized pools and modest assets almost always win with the Assumed Par Value Method. Run both every March. The deeper mechanics of the first method live on our Authorized Shares Method page.

What are the most common Assumed Par Value mistakes?

The errors we see cluster around a few predictable points. The biggest is paying the pre-filled Authorized Shares notice at face value — founders have wired tens of thousands of dollars they never owed because they never entered their issued shares and gross assets to trigger the lower calculation. A second mistake is using net assets instead of gross assets: the method requires the gross figure, so subtracting liabilities understates the input and can invite a correction on review. A third is guessing the issued-share count rather than pulling it from the cap table, which skews the assumed par per share in either direction.

Two timing mistakes also recur. Some founders try to compute Assumed Par Value before their Form 1120 balance sheet is ready and end up entering a placeholder they cannot defend. Others forget that the franchise tax is only part of the March 1 obligation — the corporation also files a $50 annual report and must keep a current registered agent on file to stay in good standing. Missing any one of these knocks the entity out of good standing even if the tax math was perfect. When in doubt, verify your current figures with an accountant before you submit; this page is general information, not tax advice.

What counts as total gross assets?

Total gross assets is the single most important input, because the assumed par per share is driven entirely by it. Delaware defines it as the total gross assets reported on your US federal Form 1120 balance sheet (Schedule L) for the corresponding accounting period. It is gross, not net — you do not subtract liabilities, loans, or payables. Cash, receivables, equipment, intangibles, and prepaid items all count toward the figure you enter.

Because the number comes straight off Form 1120, you generally need a finalized or near-final corporate return before you can compute an accurate Assumed Par Value tax. That creates a timing tension: the franchise tax is due March 1, but corporate returns are often still in progress. Most founders pull a reliable balance-sheet estimate from clean books to file on time, then keep documentation in case Delaware reviews it. Our tax filing overview and the Form 1120 guide explain how the balance sheet feeds the calculation. This is general information, not tax advice — verify your current figures with a qualified accountant.

What is the minimum, maximum, and the $50 report?

Under the Assumed Par Value Capital Method the franchise tax minimum is $400 and the maximum is $200,000 for a standard corporation. (Note the minimums differ between methods: Authorized Shares starts at $175, Assumed Par Value starts at $400 — so a corporation with a tiny share count might actually prefer the Authorized Shares minimum.) A small set of very large public companies designated as large corporate filers face a higher cap, but that does not apply to ordinary startups.

Separately, every Delaware corporation must file an annual report and pay a $50 report fee alongside the franchise tax, both due March 1. So the true minimum a corporation pays each year is $400 tax plus $50 report = $450, not counting the registered agent renewal (about $99). By contrast, a Delaware LLC files no annual report at all and pays only the flat $300 — a structural simplicity covered on our Delaware LLC cost page.

When is it due and what happens if I pay late?

The Delaware corporation franchise tax and annual report are both due by March 1 each year. This is a frequent trap because the LLC deadline is different — LLCs and LPs pay by June 1. If you run both an LLC and a corporation, you are juggling two separate dates, and mixing them up is one of the most common compliance mistakes. Our franchise tax deadlines page maps every date in one place.

Miss March 1 and Delaware adds a $200 penalty plus 1.5% interest per month on the unpaid balance, and your corporation loses its good standing. While out of good standing you cannot obtain a Certificate of Good Standing, which banks, investors, and other states routinely request. The late fee details are the same regardless of which calculation method you used — the penalty attaches to the unpaid tax, not the method. Choosing Assumed Par Value lowers the tax; it does not change the deadline.

How do I pay using the Assumed Par Value Method, step by step?

You pay through the Delaware Division of Corporations online portal using your seven-digit business entity file number. The portal defaults to the Authorized Shares figure, so the key is to switch methods before you pay:

(1) Open the franchise tax portal and enter your file number. (2) Note the pre-filled Authorized Shares amount — do not stop here if it looks high. (3) Enter your total gross assets from the Form 1120 balance sheet. (4) Enter your total issued shares from your cap table. (5) The system recalculates using the Assumed Par Value Capital Method and displays the lower of the two figures. (6) Complete the annual report fields (officer and director details). (7) Pay the tax plus the $50 report fee and save the confirmation. If you would rather not touch the portal, your specialist can run both methods and file on your behalf. See pricing for what support is included.

Does this method affect my federal taxes or BOI obligations?

No. The Delaware franchise tax — under either calculation method — is a state fee for keeping your corporation in good standing. It is entirely separate from federal corporate income tax on Form 1120, from any Form 5472information return a foreign-owned entity may owe, and from your owners’ personal returns. Choosing Assumed Par Value changes only how much franchise tax you remit to Delaware. It does not reduce or increase what you owe the IRS.

Beneficial ownership reporting is also separate. Under the March 2025 FinCEN interim final rule, BOI reporting was removed for US domestic reporting companies, and US persons are generally exempt; only certain foreign reporting companies were left with an obligation. Because this area is still evolving, confirm the current requirement directly with FinCEN or a qualified advisor — our FinCEN reporting guide and BOI report page track the latest status. None of this changes your March 1 franchise tax. Treat the franchise tax (state), federal income tax (IRS), and any BOI filing (FinCEN) as three separate calendar items. This page is general information, not legal or tax advice.

How does the Assumed Par Value Method fit non-resident founders?

Many non-resident founders form a Delaware corporation to raise from US investors, then get blindsided by the Authorized Shares notice because no one warned them the default figure is not the real bill. The Assumed Par Value Method matters even more abroad, where a surprise $80,000 demand can look like a scam or a catastrophe. Knowing you can recalculate to the $400 minimum removes that fear. Our guide for non-residents covers the full compliance picture, including how the corporation route differs from a simple LLC.

Note that non-resident owners generally cannot elect S-corp status — an S-corp election on Form 2553 requires every shareholder to be a US citizen or resident — so the Assumed Par Value Method applies to the C-corp they actually hold. For the federal identification number you will need to file Form 1120 and pay vendors, see our EIN guide or get one through our sister site ein.so. When you need a US taxpayer ID as an individual, itin.so handles ITIN applications.
