How it’s calculated

Sales tax = purchase amount × (state base rate + local rate). Your combined rate is Delaware’s state base rate plus any county or city tax you enter.

State base rate as of the latest published rates; local rates vary by jurisdiction and change over time. Confirm your local combined rate. Estimate only.

Results update as you type and are estimates, not professional advice — verify important decisions with a qualified professional.

Worked example

A $100 purchase in Delaware has $0.00 in sales tax at the 0% base rate, for a $100.00 total before any local tax.

  • Applying the rate to a tax-included total instead of the pre-tax price.

Where it is used
