Year-round tax strategy instead of once-a-year filing
Fixed-fee tax planning and preparation for construction, agriculture, attorneys, engineers, and family offices across Sioux Falls and Hartford, SD, built into year-round accounting

Quick answer
Buss CPA provides business tax preparation and planning for companies across the greater Sioux Falls, SD area, including Hartford, as part of its outsourced accounting services, which combine monthly accounting, payroll, and tax planning under one fixed fee. Construction contractors, ag operators, attorneys, engineering firms, and family offices get continuous CPA access and real-time online financial data instead of a once-a-year filing appointment.
Most tax prep in the Sioux Falls area happens the same way: drop off a folder in March, pick up a return in April, and don't think about taxes again until next year. That routine works fine if a business never changes. It falls apart the moment you're growing, hiring, buying equipment, or trying to decide whether an S-corp election makes sense before December 31.
Buss CPA builds tax planning into the accounting work we do every month, not just the six weeks before a filing deadline. Because we're already reconciling books and reviewing financials as a client's outsourced accounting department, tax-saving moves get caught in June, when there's still time to act on them, instead of next April.
One fixed monthly fee covers accounting, payroll, and tax planning together, for clients at our Hartford and Sioux Falls offices. No surprise invoice when filing season hits. No scrambling to find a CPA who has actually seen your numbers before. Just continuous access to someone who already knows your business.

Tax preparation built for construction and agricultural businesses
Contractors, farmers, and ranchers across the Sioux Falls metro and surrounding communities need different things from a tax preparer. Generic tax software doesn't know the difference, and a seasonal storefront preparer usually doesn't either.
Construction companies need job costing that ties directly into the tax return: work-in-progress schedules, percentage-of-completion accounting, and depreciation schedules for equipment that turns over every season. Get those wrong and a profitable job on paper turns into a tax bill that doesn't match the cash actually collected. South Dakota contractors managing multiple active jobs especially feel that gap.
Agriculture operations run on a different calendar entirely. Grain sales, livestock cycles, calving seasons, and equipment purchases don't follow a tidy quarterly pattern, and payroll for seasonal help carries its own withholding and reporting rules that differ from a standard W-2 workforce. Schedule F reporting for crop insurance proceeds and government payments, livestock and ranch land deductions, and planning around commodity-driven income swings all require a preparer who understands how South Dakota farms and ranches actually operate. A farm that files taxes like a retail shop leaves money on the table and risks misclassifying payroll.
Buss CPA works with both, building tax filings around how the business actually operates instead of forcing construction and agriculture clients into a template built for neither.

S-corp, LLC and entity tax planning that saves money
Entity choice is one of the biggest tax decisions a small business owner makes, and too many owners set it once at formation and never look at it again.
An LLC taxed as a sole proprietorship might have made sense at $80,000 in revenue. At $250,000, an S-corp election could mean real savings on self-employment tax, but only if payroll, reasonable compensation, and distributions are structured correctly from the start.
As part of ongoing advisory work, Buss CPA reviews entity structure annually rather than only when a client happens to ask. Construction contractors, ag operators, attorneys, engineers, and other business owners across Sioux Falls and Hartford get a second look at whether their LLC, S-corp, or partnership setup still fits their income, growth plans, and risk exposure. Entity decisions and tax planning happen together, because one shapes the other.
Secure digital tax workflows with real-time financial access
Tax shops built around paper folders and walk-in appointments were fine in 1995. Business owners across Sioux Falls, Hartford, and the surrounding area need more.
Buss CPA runs tax preparation through secure systems used for monthly accounting and payroll:
Encrypted document upload, no mailing sensitive tax records or dropping off boxes
E-signature on returns and engagement letters from any device
Real-time online access to financial statements year-round, not just at filing time
One login connecting accounting, payroll, and tax data instead of three separate systems

Tax services for attorneys, engineers, and family offices in the Sioux Falls area
Construction companies and contractors
Job costing, work-in-progress schedules, and equipment depreciation need to tie directly into the tax return. Buss CPA builds filings around how a job actually performs, not a generic business template.
Agriculture, farms, and ranches
Grain sales, livestock cycles, seasonal payroll, and Schedule F reporting don't follow a standard business calendar. Buss CPA plans around those timing differences so South Dakota ag operators aren't leaving money on the table.
Attorneys and law practices
Partnership structures, trust accounting for client funds, and owner compensation planning all carry tax implications that a general preparer often misses. Buss CPA reviews these alongside standard filing work.
Engineering firms
Projected revenue recognition, R&D-related deductions, and equity compensation for principals require planning that goes beyond a standard business return. We build that into year-round advisory.
Family offices and trusts
Multigenerational wealth, trust distributions, and estate-related tax questions need a preparer who understands both the entity and the family behind it. That's ongoing advisory work, not a once-a-year form.
What our outsourced accounting and tax process looks like
Onboarding and system setup
We connect your bank accounts, accounting software, and payroll into one secure digital workflow, then review prior returns to flag any missed opportunities.
Monthly bookkeeping and reconciliation
Your books get reconciled every month as part of the fixed monthly fee, giving us current numbers to work from instead of a year-end guessing game.
Quarterly planning check-ins
We review your financials each quarter, estimate tax liability, and flag moves, an equipment purchase, an entity change, a retirement contribution, while there's still time to act.
Year-end filing
Because the accounting and planning already happened, year-end filing is a formality built on numbers we've already reviewed together, not a scramble in March.
