Bismarck, North Dakota Sales Tax Rate

State government (capital), healthcare (CHI St. Alexius, Sanford), energy, and education. State capital and second-largest city in North Dakota.

The combined sales tax rate in Bismarck is 8.000%, composed of the North Dakota state rate of 5.000% plus a local portion of 3.000%. On a receipt, that stacks up as: State 5% + Burleigh County 1.5% + City 1.5% = 8%.

The formula to calculate sales tax for any purchase:

For a $150.00 purchase in Bismarck: tax is $12.00 ($150.00 × 0.08000), total is $162.00.

As North Dakota's capital, Bismarck hosts extensive government operations centered on North Dakota State Capitol with specific tax treatment:

Federal agencies are immune from state sales tax outright, under intergovernmental immunity rather than any North Dakota exemption. State and local bodies — including school districts — are exempt in most states on purchases for governmental purposes, though not everywhere: California taxes sales to state and local government. The distinction that catches suppliers is governmental versus proprietary. A revenue-earning activity such as a municipal utility, a parking operation or a recreation facility can be taxable at 8.000% even when the same entity buys tax-free for its governmental side. And a contractor working for a government is not exempt by association: that turns on the contract terms and on North Dakota's own rule.

Selling to state agencies and the public entities headquartered in Bismarck means paperwork before price:

A government purchase order should arrive carrying either an exemption certificate or an agency identifier; if it does not, the supplier is the one holding the exposure. State term contracts often settle the tax treatment in advance, GSA Schedule purchases follow federal rules rather than North Dakota's, and local purchasing cards have their own handling that varies by issuing body. Keep the documentation at least four years, which covers any state's audit window — the exemption certificate guide sets out what a valid certificate has to contain.

Bismarck shoppers and businesses routinely cross into Mandan, Fargo, Dickinson and beyond — and in North Dakota, the combined rate can change at those lines. Of the tracked neighbors, Mandan charges 8.250%, Fargo charges 7.750%, Dickinson charges 6.500% and Minot charges 8.500% versus Bismarck's 8.000%.

• Dickinson (95 mi): combined rate 6.500% — see the Dickinson page

Deliveries are taxed by the destination rules North Dakota applies, not by where the store sits — when an order ships across one of these city lines, re-check the rate for the exact address.

Since South Dakota v. Wayfair, a seller with no premises, staff or stock anywhere near Bismarck can still be required to register in North Dakota and charge 8.000% on what it ships here — presence stopped being the trigger and volume took over. The thresholds that decide it are in the table below; what they do not tell you is that crossing them obliges you to collect at the buyer's local rate, not a state average, which is why Bismarck and its neighbours have to be priced separately. The registration mechanics and the trailing-twelve-month counting rules are in the economic nexus guide.

Audit & Compliance Warning: Because combined tax rates combine state and local tax components, calculating tax based purely on ZIP codes can lead to errors. Many ZIP codes span multiple municipal boundaries with differing rates. For precise auditing, always use address-level geo-lookup.

Three obligations follow the 8.000% rate around Bismarck: untaxed out-of-state purchases delivered here owe matching use tax — $80.00 on a $1,000 order — self-assessed to City of Bismarck / Burleigh County; sellers with physical presence or economic nexus must register before collecting; and wholesale sales need a valid resale certificate on file at transaction time. Filing mechanics, exemption certificates, and audit preparation are covered in the North Dakota sales tax guide.

Prescription drugs are exempt from sales tax in North Dakota. Medical equipment purchased by licensed providers in Bismarck may qualify for exemptions — verify with City of Bismarck / Burleigh County.
