What is the Delaware economic nexus threshold in 2026?

There isn't one. Delaware imposes no general sales tax in 2026, so there is no dollar or transaction threshold at which a remote seller starts collecting Delaware sales tax — no volume of Delaware-destination sales creates a collection duty. You still owe sales tax in states that do impose one, so test each destination state against its own threshold rather than against Delaware's.

What lookback period does Delaware use for economic nexus?

None applies. A lookback window only matters where a state measures sales against a collection threshold, and Delaware levies no general sales tax to collect. Where you do need a window is in the states that tax: those use four different patterns — a rolling preceding 12 calendar months (Texas), the preceding or current calendar year (California), the immediately preceding four sales tax quarters (New York), and the previous calendar year only (Florida).

Do my Delaware sales count toward any other state's threshold?

No. Each state tests only the sales delivered into that state, so Delaware revenue is invisible to every other state's threshold. Track your revenue per destination state rather than in aggregate.

Do I still need to register with Delaware?

Not for sales tax — there is no Delaware sales tax registration for a remote seller to obtain. Other business-level taxes can apply to in-state activity, so confirm what your presence triggers with the Delaware revenue agency.

Delaware has no general sales tax

Delaware has no state or local sales tax. Sellers do not need to register, collect, or remit sales tax on transactions delivered to Delaware customers. However, Delaware does impose a gross receipts tax on in-state business activity.
