How do I file sales tax in Delaware?

You don't. Delaware imposes no general sales tax in 2026, so there is no Delaware sales tax permit to hold and no Delaware sales tax return to file — not even a zero return. 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.

How often do I file sales tax returns in Delaware?

Never, because Delaware levies no general sales tax and therefore assigns no filing frequency. Filing cadences (monthly, quarterly, annual) are assigned at registration by the states that do impose a sales tax, based on your expected liability there.

When are Delaware sales tax returns due?

There are no Delaware sales tax returns and so no due dates. Your deadlines live in the states where you actually hold a permit — check each of those revenue agencies' filing calendars rather than a generic rule.

Do I need a Delaware sales tax permit at all?

Not for sales tax. Delaware issues no general sales tax permit because it imposes no such tax. Other business-level taxes and licenses can still apply to in-state activity, so confirm your obligations with the Delaware revenue agency if you have people, an office, or inventory there.
