Delaware Business Taxes at a Glance
Delaware plays two roles in American business. It is where a large share of U.S. companies are formed, and it is a state where people live and businesses operate. The tax rules for each are different. A company formed in Delaware but operating elsewhere mainly deals with franchise tax and annual reports. A business actually operating in Delaware deals with gross receipts tax, income taxes, and payroll. BOMCAS helps clients in both situations.
For Companies Formed in Delaware
Every Delaware corporation files an annual report and pays franchise tax to the Division of Corporations. For most domestic corporations, the deadline is March 1. The franchise tax can be calculated in two ways: the authorized shares method and the assumed par value capital method. The authorized shares method is the default and can produce a very large bill for startups with many authorized shares. The assumed par value capital method, which uses total gross assets and issued shares, often results in much lower tax, but it requires accurate figures from the balance sheet.
Delaware LLCs, limited partnerships, and general partnerships pay a flat annual tax instead, due June 1. They do not file an annual report.
Missing these payments leads to penalties, interest, and loss of good standing, which can hold up financing or an acquisition. We calculate the franchise tax under both methods, prepare the annual report figures, and track deadlines across clients' entities.
Forming in Delaware does not change where a company owes income tax. A Delaware corporation operating in California or another state files and pays there.
Dormant Delaware Companies
Founders and investors often hold Delaware entities that are no longer active: a startup that wound down, a project company, or a subsidiary left over after a reorganization. Franchise tax and annual tax keep accruing until the entity is formally dissolved or canceled, and the Division of Corporations generally requires outstanding taxes and reports to be brought current first. We help identify inactive entities, calculate what is owed, and prepare the final federal and state returns so the entity can be closed properly with your attorney or registered agent.
Gross Receipts Tax Instead of Sales Tax
Delaware has no sales tax, so customers do not pay tax at the register. Instead, businesses pay a gross receipts tax on their total receipts from goods and services. The tax is paid by the seller and generally cannot be passed to the customer as a separate sales tax. Rates depend on the business category, and each category has a monthly or quarterly exclusion amount.
Businesses operating in Delaware also need a Delaware business license from the Division of Revenue, and gross receipts tax returns are filed monthly or quarterly depending on volume. Because the tax applies to gross receipts, it is due even when a business has no profit. We classify activities, prepare returns, and reconcile reported receipts to the books.
Corporate Income Tax
Corporations doing business in Delaware pay corporate income tax on income apportioned to the state. Corporations whose Delaware activity is limited to holding and managing intangible investments may be exempt, which is why Delaware holding companies are common. The exemption has specific conditions, and companies relying on it should confirm they qualify.
For 2026, Delaware's S corporations and partnerships no longer follow federal bonus depreciation and certain related federal expensing provisions. This creates separate Delaware depreciation schedules for affected pass-through entities. We keep those schedules alongside the federal ones.
Personal Income Tax and Wilmington's City Wage Tax
Delaware taxes residents' income at graduated rates and taxes nonresidents on Delaware-source income. Many people who work in Delaware live in Pennsylvania, New Jersey, or Maryland, and those states have their own rules for credits and allocation.
The City of Wilmington also imposes an earned income tax on residents and on nonresidents who work in the city, as well as a net profits tax on businesses in the city. Remote and hybrid workers need clear records of where they worked. We prepare state and city returns and review allocations for commuters.
Payroll and Delaware Paid Leave
Delaware employers withhold state income tax and, where applicable, Wilmington's city tax. They report unemployment insurance to the Department of Labor. Delaware Paid Leave added another payroll item: contributions began on January 1, 2025, and employees could begin claiming benefits on January 1, 2026. Employers file quarterly hours and wage reports for the program and can share part of the cost with employees.
We set up and run payroll, handle the quarterly filings, and reconcile payroll to the general ledger.
Banks, Startups, Chemicals, and Beach Businesses
- Financial services and banking: Delaware's large banking and credit card sector, along with smaller firms that serve it
- Holding companies and startups: franchise tax calculations, intangible holding company rules, and multistate operations
- Chemicals, manufacturing, and life sciences: inventory, fixed assets, and research credits on federal returns
- Beach tourism and hospitality: seasonal payroll and lodging taxes
Bookkeeping That Supports Delaware Filings
For Delaware-formed companies, the key numbers are total gross assets and issued shares, which drive the franchise tax under the assumed par value capital method. For businesses operating in Delaware, the key numbers are gross receipts by category. We keep the books so these figures are accurate and documented when filing dates arrive.
