Delaware Internet Sales Tax

Learn about the Internet sales tax rules for Delaware.



Update: Below is an article on the Internet sales tax rules for this state prior to the Supreme Court's decision in South Dakota v. Wayfair Inc. on June 21, 2018. The Wayfair decision overturned the prior rule established in Quill Corporation v. North Dakota which prohibited states from requiring a business to collect sales tax unless the business had a physical presence in the state. Some states already had laws prior to the Wayfair decision (commonly referred to as Amazon Laws) that require larger Internet sellers without a physical presence in the state to collect and pay sales tax under certain circumstances. It is expected that states will now pass new laws requiring online retailers to collect sales tax for sales within their state. We will update this article as the laws change.

Delaware is one of five states with no sales tax. The others are Alaska, New Hampshire, Montana, and Oregon. Therefore, if you are selling goods or products over the Internet to customers located in Delaware, sales tax for those customers should be a non-issue.

However, at the federal level, Congress has repeatedly considered legislation that would affect large Internet retailers and how online sales taxes are collected in all states. The most recent form of a proposed federal law is the Marketplace Fairness Act of 2015. As in previous versions, the 2015 Act would allow states to require sellers not physically located in their state to collect taxes on online and catalog sales made to people in their state. Sellers that make $1 million or less in annual sales and have no physical presence in the state would be exempt from this requirement. States would have to meet certain criteria to simplify their sales tax laws and make sales tax collection easier before they could require sellers to collect the tax.

Delaware’s Gross Receipts Tax

While there is no sales tax in Delaware, the state does have a gross receipts tax, which is briefly discussed on a Delaware Division of Revenue FAQ page. The tax is also codified in Chapter 29 of Title 30 of the Delaware Code. Note, however, that it appears this tax applies only to retailers and other businesses located in, and therefore required to be registered in, Delaware. Moreover, a retailer can deduct the first $100,000 in aggregate gross receipts each month prior to having to pay the tax. In short, if you are an out-of-state Internet seller, you are not likely to need to concern yourself with Delaware’s gross receipts tax.

For States That Do Have Sales Tax

The current default rule throughout the United States is that you must collect sales tax on Internet sales to customers in those states where your business has a physical presence—assuming, of course, that the state involved has a sales tax. The physical presence rule is based on a 1992 United States Supreme Court decision, Quill Corp. v. North Dakota, that addressed the obligations of mail order businesses to collect sales tax on out-of-state sales; the decision has been extended to include online retailers. Generally speaking, a physical presence means such things as having:

  • a warehouse in the state
  • a store in the state
  • an office in the state, or
  • a sales representative in the state.

The corollary to the physical-presence rule is that, if you do not have a physical presence in the state, you generally are not required to collect sales tax for an Internet-based sale to someone in that state.

However, because Delaware has no state sales tax, these rules are not relevant to sales you make to Delaware customers.
