Returns for a Government Town
In Pierre, a large share of private business sells to government or works around it: engineering and IT firms with state contracts, consultants and lobbyists, printers, caterers, office suppliers and builders who maintain public buildings. Alongside them are statewide associations and nonprofits, river and hunting businesses, and ranch operations from both sides of the Missouri. None of them pays South Dakota income tax, so the annual filing is federal: a corporate, S corporation or partnership return, Schedule C for a sole owner, or Form 990 for an exempt organisation. BOMCAS prepares these returns for Pierre clients remotely.
Statewide due dates and entity choices are set out under South Dakota business tax preparation; this page covers Pierre contractors, associations, lodges and ranches.
Government Contractors and Consultants
Firms that work under state or federal contracts often bill by milestone or on cost-plus terms, carry retainage and wait on payment cycles that do not match their own year end. Their returns depend on when revenue is recognised, how unbilled work and receivables are treated and whether the business can use the cash method. Consultants and lobbying firms should also be aware that lobbying and political expenses are generally not deductible, and that dues paid to associations may be partly non-deductible when the association lobbies.
Associations and Nonprofits
Trade associations are usually exempt under section 501(c)(6) and charities under 501(c)(3). Both file an annual Form 990, 990-EZ or 990-N depending on size, and both may owe tax on unrelated business income, such as advertising in a member magazine or sponsorship arrangements that look like advertising. Associations that lobby must either tell members what share of dues is non-deductible or pay a proxy tax. Annual conferences held during or around the session, with exhibitor fees, sponsorships and hotel blocks, need careful classification.
Lodges, Guides and River Businesses
Fishing guides, hunting lodges, marinas and bait shops near Lake Oahe have seasonal revenue, boats, motors, vehicles and land leases. Their returns separate the taxes collected from guests, depreciate boats and equipment correctly and deal with deposits taken before year end for next season's trips.
Ranch and Farm Entities
Ranches west of the river and farms east of it often operate through family partnerships or corporations. Cattle held for breeding, raised calves sold each autumn, grazing leases on private and federal land, crop insurance and conservation payments all appear on the return, and the treatment of livestock sold because of drought can allow income to be deferred.
Builders and Trades
Pierre's residential contractors hold a city licence and every contractor pays the 2 percent contractor's excise tax on realty improvement receipts. Public work on state buildings, schools and city projects is common, and those contracts should be reconciled to the excise tax filings and the federal return.
Retail and Restaurants
Retailers and restaurants have a winter bump during the legislative session and a summer bump from visitors. Their returns must exclude the sales, gross receipts and tourism taxes collected, and from July 2027 the Hughes County tax as well.
Professional Offices
Law firms, engineering and surveying offices, insurance agencies and medical practices serve both the public sector and the wider region from Pierre. Most are S corporations or partnerships, and the recurring questions are reasonable salaries for owners, retirement plan contributions, partner buy-ins and the deduction limits for meals and entertainment with clients.

Pierre Business Tax Preparation Questions
Does a Pierre company file a South Dakota income tax return?
No. South Dakota has no corporate or personal income tax, so the business files federal returns and any other states' returns its work requires.
Are lobbying costs deductible?
Generally not. Lobbying and political expenses are non-deductible, and part of the dues paid to associations that lobby may be non-deductible too.
Which Form 990 does our association file?
It depends on gross receipts and assets: Form 990-N for the smallest organisations, 990-EZ for mid-sized ones and the full Form 990 above those limits.
Can a rancher defer income from a drought sale?
In qualifying drought areas, ranchers who sell more livestock than usual can often defer the extra gain by one year or replace the animals within a set period.
Talk to BOMCAS About Business Tax Preparation in Pierre
Accurate returns depend on closed monthly books, reconciled payroll and correct sales and excise tax filings. Owners' personal returns follow from the K-1s, the results feed next year's planning, missing years and lapsed Form 990s go through catch-up filing, and Canadian members or clients raise cross-border questions. For work elsewhere in the state, we keep South Dakota pages on personal tax, sales and use tax, bookkeeping, payroll, tax planning, back taxes and cross-border tax, linked from the South Dakota overview.
