Delaware
Gross receipts tax
Delaware does not impose a state or local sales tax; however, it does levy a gross receipts tax on businesses selling goods (both tangible and intangible) or providing services within the state. Unless explicitly stated by law, "gross receipts" refers to the total income a business earns from goods sold and services provided in Delaware. No deductions are allowed for expenses such as the cost of goods sold, labor, interest, discounts, delivery, or state and federal taxes.
The gross receipts tax rates for businesses in Delaware vary between 0.0945% and 1.9914%, depending on the nature of the business activity.
