Sales Tax in a City Split Between Counties
Box Elder straddles the Pennington–Meade county line, so sellers sometimes ask which county's rules apply. For 2027 the answer is simple: both counties adopted the same half-percent tax starting January 1, 2027, so a sale anywhere in the city carries the same rate. What does vary is where your customers are. Deliveries to Rapid City, Piedmont, Sturgis, New Underwood or rural addresses carry that location's rates. BOMCAS prepares Box Elder sales tax returns remotely and keeps each jurisdiction straight.
Licensing and taxable services statewide are explained under South Dakota sales and use tax, while Box Elder's codes, the base and the two-county 2027 change are covered here.
Box Elder Rates
- General sales and services: 6.2 percent through December 2026, 6.7 percent from January 2027 and 7.0 percent from July 2027.
- Restaurant food, alcohol, lodging and admissions: one more point for the city's gross receipts tax under code 037-1.
- Lodging under 28 days: the 1.5 percent tourism tax as well, plus $2 per occupied room night at hotels in Business Improvement District No. 1.
Selling on the Base
Ellsworth Air Force Base is federal land within Pennington and Meade counties, but it is not inside Box Elder's city limits. A Box Elder business delivering goods to a customer on base generally charges state tax and the county tax that applies there, not Box Elder's municipal tax. Sales made directly to the federal government, paid with government funds, are exempt with proper documentation; sales to airmen buying for themselves are not.
Contractors on Federal Projects
Construction for the federal government at Ellsworth is still subject to South Dakota's 2 percent contractor's excise tax on the prime contractor's gross receipts, and contractors generally pay sales or use tax on materials they install. Subcontractors who are not prime contractors usually do not owe the excise tax on their portion if they receive a prime contractor's exemption certificate, but they still pay tax on their materials. Projects spanning January and July 2027 need materials budgets that reflect the county tax and the higher state rate.
Homebuilders
A builder putting up a spec house on its own lot and a builder working under contract for a buyer who already owns the lot are both realty improvement contractors in South Dakota, but the timing and base of the contractor's excise tax can differ between the two. The Department of Revenue's contractor guide sets out how each is figured, and builders should set up each project correctly from the start so the tax is reported in the right period.
New Businesses
A new shop, restaurant or service business needs a South Dakota sales tax licence before its first taxable sale, in addition to the Box Elder business licence. Many services are taxable in South Dakota, including repairs, cleaning, photography and personal care, so service businesses should check before opening.
Online and Home-Based Sellers
Military spouses selling online from Box Elder may owe sales tax in other states once their sales into those states pass the threshold for remote sellers, and marketplace sales are usually handled by the platform. Sales to local customers are taxed at the Box Elder rate.
Filing
We file monthly or less frequent returns as allowed, reconcile them to sales reports, track exemption certificates and update rates for both 2027 changes.
Use Tax on Equipment Bought Elsewhere
A Box Elder business that buys equipment or supplies online or out of state without paying South Dakota tax owes use tax at the Box Elder rate. We review purchases each period so it is reported on the return rather than found later in an audit.
Box Elder Sales and Use Tax Questions
Does it matter which county my Box Elder shop is in?
Not for the 2027 rate. Pennington and Meade counties both adopted the same half-percent tax.
Do I charge Box Elder city tax on deliveries to the base?
Generally no. The base is outside city limits, so state tax and the applicable county tax apply.
Do subcontractors on Ellsworth projects owe contractor's excise tax?
Usually the prime contractor pays it. Subcontractors with a prime contractor's exemption certificate generally do not, but they still pay tax on materials.
What is the hotel charge in Box Elder?
Hotels in Business Improvement District No. 1 charge $2 per occupied room night.
Talk to BOMCAS About Sales and Use Tax in Box Elder
Separate tax accounts in the books make returns simple, and the totals flow to the business return. Crews run through payroll, unfiled periods through catch-up filing, purchases before 2027 are a planning matter, home sellers report profit on personal returns, and sales abroad raise cross-border issues. If you also have work in other parts of the state, our South Dakota pages on business returns, personal returns, bookkeeping, payroll, tax planning, late filing and cross-border tax sit under the state overview.
