Delaware Business Taxes: A Complete Guide for Incorporated Companies
More than 1.9 million businesses—including over 60% of Fortune 500 companies—are incorporated in Delaware. But why? And more importantly, what does that mean for your tax obligations?
Whether you're already incorporated in Delaware or considering it, understanding the state's unique tax structure can save you money and prevent costly compliance mistakes. This guide breaks down every tax you may owe to the state of Delaware, when it's due, and how to calculate it.
Why Delaware Is So Popular for Incorporation
Delaware's appeal isn't accidental. The state offers a sophisticated legal framework through its Court of Chancery (a business-friendly court system with no jury trials), flexible corporate laws, and strong privacy protections. But perhaps the biggest draw is the tax treatment:
Non-Delaware residents pay no Delaware state income tax on profits from their Delaware-incorporated business—as long as the business doesn't operate in Delaware. That means you can incorporate in Delaware, run your business from California or Texas, and owe zero state income tax to Delaware.
This is a significant advantage for founders and investors who want the legal protections of Delaware incorporation without the tax burden.
Delaware Business Tax Types at a Glance
Before diving into specifics, here's a quick overview of the taxes Delaware businesses may encounter:
| Tax Type | Who Pays | Rate |
|---|---|---|
| Franchise Tax | Delaware corporations | Varies by method |
| Corporate Income Tax | C-Corps with DE-source income | 8.7% |
| Personal Income Tax | Residents and those with DE-source income | 2.2%–6.6% |
| LLC Annual Fee | Delaware LLCs | $300 flat |
| Gross Receipts Tax | Businesses operating in Delaware | 0.1%–1.9917% |
Delaware Franchise Tax
If your business is incorporated as a corporation in Delaware, you must pay the annual franchise tax—regardless of whether you conduct any business in the state or earn any income there.
Who Pays It
All Delaware-incorporated corporations. This includes:
- C-Corporations
- S-Corporations
LLCs, limited partnerships (LPs), and general partnerships (GPs) are exempt from franchise tax (they pay a separate annual fee instead).
How It's Calculated
Delaware offers two methods to calculate franchise tax, and you get to choose whichever results in a lower amount:
Method 1: Authorized Shares Method
- 5,000 shares or fewer: $175 minimum tax
- 5,001–10,000 shares: $250
- Each additional 10,000 shares (or portion): add $85
- Maximum tax: $200,000
Method 2: Assumed Par Value Capital Method This method is more complex but often significantly lower for startups with many authorized shares and little paid-in capital. It's calculated by dividing total gross assets by total issued shares to determine an "assumed par value," then multiplying by the number of authorized shares.
Delaware's Division of Corporations provides a spreadsheet calculator on their website to help you determine which method works in your favor.
When It's Due
The franchise tax is due March 1st for corporations. Filing is done electronically through Delaware's Division of Corporations portal.
Late payment penalty: $200 plus 1.5% monthly interest on the unpaid balance. Missing this deadline adds up quickly, so mark it on your calendar.
Delaware Corporate Income Tax
The franchise tax and corporate income tax are two separate obligations. A corporation may owe both.
Who Pays It
C-Corporations that have income allocated to Delaware. The key phrase here is "Delaware-sourced income." If your Delaware-incorporated C-Corp operates entirely outside the state, you generally won't owe Delaware corporate income tax.
The Rate
Delaware's corporate income tax rate is 8.7% on federal taxable income that's allocated to the state. This is applied after federal adjustments—not on your total federal taxable income.
Filing Form
C-Corps file using Form 1100 (or Form 1100EZ for qualifying smaller corporations). The return is due by the 15th day of the fourth month following the close of the tax year (typically April 15 for calendar-year corporations).
Delaware Personal Income Tax
Delaware residents pay state income tax on their worldwide income. Non-residents pay only on income sourced from Delaware.
Tax Brackets (2024)
| Taxable Income | Tax Rate |
|---|---|
| $0–$2,000 | 0% |
| $2,001–$5,000 | 2.2% |
| $5,001–$10,000 | 3.9% |
| $10,001–$20,000 | 4.8% |
| $20,001–$25,000 | 5.2% |
| $25,001–$60,000 | 5.55% |
| Over $60,000 | 6.6% |
For pass-through entities like S-Corps and partnerships, business profits flow to the owners' personal returns. Delaware residents report this income on their personal return; non-residents only owe Delaware tax if the income is sourced from Delaware operations.
Sole Proprietors
If you're a sole proprietor and a Delaware resident, your business profits are taxed at these same personal income tax rates. File using Form 200-01.
Delaware Annual Reports and Filing Requirements
Corporations
Delaware corporations must file an annual report by March 1st each year. The filing fee is $50. This is filed alongside (but separately from) the franchise tax payment.
LLCs, LPs, and General Partnerships
These entities are not required to file an annual report, but they must pay an annual fee of $300 by June 1st. There's no separate franchise tax for these entity types.
Miss the June 1 deadline and you'll face a $200 penalty plus 1.5% monthly interest.
Delaware Gross Receipts Tax
Unlike most states that rely on sales tax, Delaware has no sales tax. Instead, businesses that physically operate in Delaware may be subject to a gross receipts tax on total revenues—not profits.
Key Features
- Applied to businesses with a physical presence or operating activities in Delaware
- Rate varies by industry, ranging from approximately 0.1% to 1.9917%
- Businesses with annual gross receipts under $100,000 in most categories may qualify for exemptions
- Filed monthly or quarterly depending on revenue volume
If you're incorporated in Delaware but conduct all operations outside the state, the gross receipts tax typically doesn't apply to you.
Withholding Requirements for Delaware Employers
If your business employs workers in Delaware, you must register as a Delaware employer and withhold state income tax from employee wages.
- Register with the Delaware Division of Revenue
- Withholding deposits are due monthly or quarterly depending on your liability
- File annual reconciliation (Form W-3) by January 31st
- Provide employees with Delaware W-2 forms

Common Delaware Tax Mistakes to Avoid
1. Confusing franchise tax and income tax Many business owners receive a surprise Delaware franchise tax bill even though their company has no Delaware revenue. These are two separate obligations—don't assume paying one covers the other.
2. Defaulting to the Authorized Shares Method Delaware defaults to the Authorized Shares Method when you file, which can be enormous for startups with millions of authorized shares (common for venture-backed companies). Always calculate using both methods and choose the lower amount.
3. Missing the LLC annual fee deadline The LLC annual fee due date (June 1) is separate from corporate deadlines. Many LLC owners miss it because it flies under the radar—there's no income-based return to file, just a flat $300 fee.
4. Assuming non-residency means zero Delaware obligations Even if you live outside Delaware, your Delaware-incorporated company still owes the franchise tax and filing requirements. "No income tax" doesn't mean "no taxes at all."
5. Forgetting about gross receipts tax if you operate in Delaware If your business sells products or services in Delaware (not just incorporated there), you may owe gross receipts tax. Always verify based on where your actual business activities occur.
Delaware vs. Other Popular Incorporation States
| Feature | Delaware | Wyoming | Nevada |
|---|---|---|---|
| Franchise tax | Yes (varies) | No | Minimal |
| Income tax | 8.7% (C-Corps) | None | None |
| Court of Chancery | Yes | No | No |

Delaware wins on legal infrastructure; Wyoming and Nevada win on lower taxes. For most funded startups and large corporations, Delaware's legal advantages outweigh the tax cost.
