Why Delaware C-Corps need more than basic bookkeeping
A Delaware C-Corp has filings that generic small-business software does not track. The franchise tax and $50 annual report fee are due March 1 each year, and under 8 Del. C. §503 you owe the lower of the Authorized Shares Method and the Assumed Par Value Capital Method only if you report gross assets and issued shares.
The gap is large. A company with 10,000,000 authorized shares owes $85,165 under the Authorized Shares Method. With 15,000,000 authorized shares it is $127,665. Under the Assumed Par Value Capital Method, a typical early-stage company owes the $400 minimum or a little more. Whoever keeps your books needs to know to produce the gross asset figure from Schedule L of your Form 1120 and file under the right method.
Beyond franchise tax, a Delaware C-Corp also needs a federal Form 1120 every year, foreign qualification and state returns where it operates, a registered agent, and accrual-basis financial statements that investors can read.
Types of accounting providers and what they usually cover
Rather than compare list prices, which change often, compare what each type of provider covers.
- Accounting software alone. Lowest cost. You or a contractor do the categorization. Franchise tax, Form 1120 and state filings are separate.
- Bookkeeping-only services. Monthly categorization and reconciliations, often on a cash basis. Tax returns and Delaware filings are usually extra or not offered.
- Startup-focused accounting firms. Accrual books, financial statements and often tax preparation and Delaware compliance, either bundled or as add-ons. Pricing typically scales with transaction volume and entity count.
- Fractional CFO firms. Budgeting, board reporting and fundraising support on top of the books. Useful after a priced round, more than most pre-seed teams need.
Ask each provider for a written list of what the monthly fee covers and a quote for everything else for a full year.
Hidden costs that make cheap accounting expensive
Three costs regularly surprise founders after they pick a provider on monthly price.
First, tax preparation. Many bookkeeping plans exclude the federal Form 1120 and state income or franchise tax returns. Add those quotes to the monthly fee × 12 to get the real annual cost.
Second, Delaware penalties. Missing March 1 costs a $200 penalty plus 1.5% interest per month on the tax and penalty, and a provider who files without gross assets leaves you with the Authorized Shares Method bill.
Third, cleanup before a financing or audit. Cash-basis books, unrecorded SAFEs, missing stock compensation entries and unreconciled accounts all have to be fixed before a Series A lead's diligence or a first audit. Cleanup work is usually billed hourly and costs more under deadline pressure than doing it monthly.
Worked example: comparing total annual cost
Compare providers on a full year of cost, because the monthly price is only one line of the bill. Here are two hypothetical quotes for a seed-stage Delaware C-Corp with one bank account, a few cards and a small payroll.
| Cost item | Provider A (bookkeeping only) | Provider B (bundled) |
|---|---|---|
| Monthly bookkeeping × 12 | $3,600 | $7,200 |
| Form 1120 and state returns | $2,000 | Included |
| Delaware annual report filing | $250 | Included |
| Year-end accrual cleanup | $3,000 | Included |
Provider A looks half the price at $300 a month, but the year costs $8,850. Provider B at $600 a month costs $7,200. These are illustrative numbers, not market quotes, and either provider could be the better deal depending on what your company actually needs.
State fees are the same whichever provider you use: the $50 annual report fee plus franchise tax, which for most early-stage companies filing under the Assumed Par Value Capital Method is the $400 minimum. Add the registered agent fee and any foreign qualification fees in states where you operate.
Ask each provider to fill in a table like this one before you sign. If they cannot, you do not yet know the price.
Annual compliance calendar for a Delaware C-Corp
A calendar-year Delaware C-Corp has a short list of fixed deadlines, and a good provider tracks all of them. The main federal and Delaware dates:
- January 31. Forms W-2 for employees and Form 1099-NEC for contractors. For payments made after December 31, 2025, the 1099-NEC threshold is $2,000 per payee, up from $600.
- March 1. Delaware annual report, $50 fee and franchise tax. Late filing costs $200 plus 1.5% interest per month or portion of a month.
- April 15. Form 1120, due the 15th day of the 4th month after year end. Form 7004 extends the filing deadline six months to October 15, but not the time to pay any tax owed.
- Quarterly. Federal estimated tax payments on the 15th of the 4th, 6th, 9th and 12th months if the company expects to owe tax. Most pre-profit startups owe none, but check once revenue grows.
- State dates. Income or franchise tax returns and annual reports in each state where you are registered, on that state's schedule.
One filing you can drop: FinCEN's beneficial ownership (BOI) reporting no longer applies to companies formed in the United States, so a Delaware C-Corp does not file a BOI report. Be wary of mailers that say otherwise.
Accrual books and when to upgrade from basic bookkeeping
Move from basic cash-basis bookkeeping to accrual accounting no later than your first priced round, and earlier if you sell annual contracts or carry significant payables. Investors, lenders and auditors read financial statements prepared under US GAAP, which uses accrual accounting. Federal tax rules also require accrual accounting for C-Corps whose average annual gross receipts exceed the inflation-adjusted threshold in IRC §448(c), though most early-stage startups fall well below it.
Signs you have outgrown the cheapest option:
- You raised on SAFEs or notes and they are not on the balance sheet.
- You sell annual or multi-year subscriptions and record the full payment as revenue when cash arrives.
- You have employees or contractors in more than one state.
- Your board or lead investor wants a monthly package with a balance sheet, income statement and cash flow statement.
- You plan to claim the R&D credit, which needs clean payroll and contractor data by project.
Fixing any one of these after the fact costs more than doing it monthly, which is the main reason the cheapest provider is rarely the cheapest outcome.
What to look for in a Delaware C-Corp accounting provider
Minimum requirements for a venture-backed Delaware C-Corp:
- Accrual-basis bookkeeping and monthly close
- Balance sheet, income statement and cash flow statement each month or quarter
- Delaware annual report and franchise tax filed under the Assumed Par Value Capital Method

Frequently asked questions
What is the cheapest accounting option for a Delaware C-Corp?
The cheapest option is the one with the lowest total annual cost, not the lowest monthly fee. Add monthly bookkeeping × 12, Form 1120 and state return preparation, the Delaware annual report filing and any year-end cleanup. A bookkeeping-only plan that excludes tax returns and Delaware filings often costs more over a year than a bundled startup accounting provider.
How much does a Delaware C-Corp pay in state fees each year?
Most early-stage Delaware C-Corps pay $450 a year to the state: the $50 annual report fee plus the $400 minimum franchise tax under the Assumed Par Value Capital Method. Companies that file without reporting gross assets and issued shares are taxed under the Authorized Shares Method, which is $85,165 for 10,000,000 authorized shares. Registered agent fees are separate.
Does a Delaware C-Corp need to file a tax return if it has no revenue?
Yes. Every domestic corporation must file Form 1120 each year unless it is tax-exempt, even if it had no income or activity. For a calendar-year corporation the return is due April 15, or October 15 with a Form 7004 extension. The company must also file the Delaware annual report and franchise tax by March 1, regardless of revenue.
Do early-stage startups need accrual accounting?
Most venture-backed startups should switch to accrual accounting by their first priced round. Investors and auditors expect US GAAP financial statements, which use accrual accounting, and accrual books are needed to record SAFEs, deferred revenue on annual contracts and stock-based compensation correctly. Federal tax law separately requires accrual accounting for C-Corps above the IRC §448(c) gross receipts threshold.
Does my Delaware C-Corp need to file a BOI report with FinCEN?
No. FinCEN revised its beneficial ownership reporting rule in 2025 so that companies formed in the United States, including Delaware C-Corps, are not required to file BOI reports. The requirement now applies only to certain entities formed under foreign law and registered to do business in a US state. Ignore mailers that demand a BOI filing fee from a US company.
