Delaware Corporation Taxes

Delaware corporations can face both entity-level income tax and separate annual business taxes, depending on whether the company is treated as a C corporation, an S corporation, or a corporation subject to a separate franchise or margin-tax regime. This guide is rendered from the source-backed tax profile so future updates stay tied to official state tax sources.

Corporate Income Tax

The current Delaware profile lists a C corporation rate of 8.7% and an S corporation rate of see official guidance.

Use the current corporate income tax FAQs and annual report instructions together for Delaware corporation tax maintenance.

If your company elected S corporation treatment federally, do not assume the state follows federal law automatically. The state profile is the right place to confirm whether the state recognizes the election and whether it still imposes a separate entity-level tax.

Franchise, Margin, Gross Receipts, and Other Business Taxes

The current profile shows the following business-tax items:

Franchise Tax (llc): $300 flat annual tax for domestic and foreign LLCs; Delaware corporations use a separate franchise tax computation. Due: June 1.
Gross Receipts Tax (all businesses): Gross receipts tax can apply to Delaware businesses even though Delaware has no retail sales tax.

These taxes can apply in addition to corporate income tax. That distinction matters because a corporation may owe a minimum, franchise, or margin-style tax even in a low-profit year.

Sales Tax for Corporations

Delaware does not currently impose a general state sales tax. Delaware does not impose a state retail sales tax.

If the corporation sells taxable goods or taxable services, use the state tax authority for registration and rate verification. The current profile points to: see official guidance.

Filing Planning and Entity Choice

The state tax profile is also useful for entity-choice planning. If the S corporation rate, minimum tax, or PTE election rules are materially different from the C corporation rules, that can change whether an S election makes sense. The right comparison is not just federal tax savings; it is the full state stack of income tax, minimum tax, franchise tax, sales tax, and annual compliance cost.

State-Specific Quirks

Entity-choice split: Delaware combines no sales tax with separate LLC annual taxes, corporate franchise tax, and gross receipts tax depending on entity and activity.

Bottom Line

For a Delaware corporation, the main compliance risk is overlooking the extra layer beyond ordinary corporate income tax. Check the minimum tax, the separate business-tax regime, and the state's sales-tax registration rules every time the profile is refreshed.
