Returns for a City Built Around a Base
Box Elder businesses tend to be young. Many opened in the last five years to serve a growing population, and many depend directly or indirectly on Ellsworth. That brings particular questions: how to report a federal subcontract that spans three tax years, how to handle start-up costs, what happens when an owner receives orders and the business must run without them. South Dakota has no business income tax, so the federal return is the main filing. BOMCAS prepares business returns for Box Elder firms remotely.
Entity choices and federal due dates for every South Dakota firm are on our state business tax page. Below are the Box Elder cases: base subcontractors, builders and new businesses.
Subcontractors on Base Projects
The large construction contracts at Ellsworth are held by national firms, but much of the work flows to local and regional subcontractors: earthwork, concrete, electrical, mechanical, fencing, roofing and finishes. Their returns depend on how long-term contracts are reported, whether the small contractor exception permits the completed-contract method, how retainage is treated and how mobilisation costs are allocated. Because federal work usually requires Davis-Bacon wages and certified payroll, labour costs are well documented, and those records should tie to the job costs on the return.
Homebuilders and Developers
Builders putting up houses for sale treat them as inventory, while developers who keep apartments or rental homes depreciate them. A builder who rents unsold homes to military families while waiting for buyers needs to decide how those homes are treated. Land development costs, including streets and utilities, must be allocated across lots, and impact fees and city charges are generally capitalised.
Starting a Business
For new businesses, the first return sets patterns that last. Up to $5,000 of start-up costs and $5,000 of organisation costs can usually be deducted in the first year, with the rest amortised. Equipment bought before opening, a franchise fee, the lease build-out and loans from the owner each need correct treatment. We help new owners choose an entity, set up the books and prepare the first return.
Businesses Owned by Military Spouses
A spouse who runs a bakery, photography business, salon or online shop from Box Elder may move in two or three years. The business can often continue remotely or close and reopen elsewhere. Returns need to reflect where the work was performed, especially if the spouse's legal residence is a state with an income tax, and any business assets moved or sold need proper treatment.
Franchises and Service Businesses
Restaurants, auto services, fitness centres and child care operators along the interstate deal with franchise fees and royalties, equipment depreciation, tip reporting and payroll credits. Child care providers may also have state grants or subsidies that are taxable income.
What We Review

Getting Started
Send your accounting file or trial balance, contract schedules, bank and loan statements, payroll reports, sales and excise tax returns and last year's return. We prepare one list of questions and review the return with you before filing.
Selling to the Government
Box Elder firms that sell directly to Ellsworth, rather than through a prime contractor, register in the federal SAM system and are paid electronically by the government. Those payments are reported to the IRS, so the revenue on the return should match the federal payment records. Firms that also sell to airmen privately keep the two streams separate in the books, which helps both the income tax return and the sales tax return.
Box Elder Business Tax Preparation Questions
How do I report a base subcontract that lasts several years?
Long-term contracts usually use percentage-of-completion unless the small contractor exception allows another method. We review your contracts and receipts.
Can I deduct the costs of starting my business?
Usually up to $5,000 of start-up costs and $5,000 of organisation costs in the first year, with the rest spread over 15 years.
I rent out unsold spec homes. How are they treated?
It depends on whether they are still held for sale. The answer affects depreciation and how a later sale is taxed.
Does my Box Elder business owe state income tax?
Not in South Dakota. It may owe returns in other states where it works or sells.
Talk to BOMCAS About Business Tax Preparation in Box Elder
A return is only as good as the monthly books, the certified payroll and the excise and sales tax filings behind it. Owners' household returns pick up the K-1s, the numbers drive planning for the next contract, missed years go through catch-up filing, and work or partners abroad raise cross-border questions. If you also have work in other parts of the state, our South Dakota pages on personal returns, sales and use tax, bookkeeping, payroll, tax planning, late filing and cross-border tax sit under the state overview.
