Planning Around Harvest and Year End
Many Aberdeen planning conversations happen in November and December, after harvest but before year end, when farmers, dealers and business owners know roughly how the year turned out. That timing gives room to act on grain sales, input purchases and equipment. Planning works better, though, when it starts earlier and includes the whole household. BOMCAS works with Aberdeen clients remotely and reviews federal and, where needed, North Dakota tax before decisions are final.
Our South Dakota tax planning page gives the strategies that work anywhere in the state; this page applies them to Brown County farms, Aberdeen owners, health professionals and retirees.
Farm Families
Farm tax planning in Brown County often concerns smoothing income across years. Options include deferred payment contracts for grain, deferring crop insurance proceeds when the crop would normally be sold the next year, prepaying inputs within the federal limits, farm income averaging and timing machinery purchases. Depreciation can wipe out income in one year and leave little for the next, so we look at several years at once. Farmers with off-farm wages should also consider retirement contributions and health savings accounts.
Succession and Land
Farm and ranch land around Aberdeen has risen in value, and many families are planning a transfer to the next generation. Choices among gifting, sales on instalment, leases and keeping land until death have very different income and estate tax effects. Land held until death generally receives a stepped-up basis, while gifted land keeps the donor's basis. Entity structures can help divide management and ownership. We work alongside your attorney and lender on the tax side of these plans.
Business Owners
For Aberdeen dealers, manufacturers and service businesses, planning covers entity choice, owner salary in S corporations, the qualified business income deduction, retirement plans and the timing of equipment. The 2025 federal tax law restored 100 percent bonus depreciation for qualifying property acquired after January 19, 2025 and permanently allowed immediate deduction of domestic research costs, which matters for local manufacturers doing engineering work. We also review whether operations in North Dakota create income tax filings there.
Health Professionals and High Earners
Physicians, dentists and other professionals working near Avera St. Luke's and Sanford Aberdeen often have high earnings early in their careers. Planning can include practice entity structure, cash balance or defined benefit plans, backdoor Roth contributions, donor-advised funds and student loan strategy. Those with income from more than one practice need estimated payments adjusted accordingly.
Retirees and Charitable Giving
South Dakota does not tax retirement income, so Aberdeen retirees plan only for federal tax and, sometimes, a former state. Qualified charitable distributions from IRAs can satisfy required distributions without increasing taxable income, which suits retirees who give to local churches, foundations and Northern State. Roth conversions in lower-income years can reduce future required distributions.
University and Public Employees
Northern State faculty and staff, along with school district, city and county employees in Aberdeen, usually belong to the South Dakota Retirement System and may contribute to a supplemental 457 plan. Contributing to both a 403(b) or 457 plan and an IRA can raise savings well above what many employees realise. Public employees nearing retirement should plan the order of withdrawals and the start date of Social Security together with the pension.
North Dakota Income in the Plan
Aberdeen residents who earn wages, rent or business income in North Dakota have a second tax return to plan. North Dakota's rates are low, and its first bracket is taxed at zero, but the amount owed depends on total federal income, so a large farm year or bonus in South Dakota can increase North Dakota tax on a modest North Dakota job. Business owners should also consider whether expanding into North Dakota creates corporate income tax, withholding or workers' compensation obligations before committing.
Purchases Before the 2027 Rate Increase
South Dakota's state sales tax rate is scheduled to rise from 4.2 to 4.5 percent on July 1, 2027. Brown County voters rejected a county sales tax in 2026, so the increase is the main change Aberdeen buyers face. Businesses planning large taxable purchases, such as equipment, furnishings or building materials, can consider timing (motor vehicles carry a separate state excise tax instead), but the tax saving is small compared with the business reasons for the purchase.
Aberdeen Tax Planning Questions
When should Aberdeen farmers start year-end planning?
Ideally in late summer, once yields and prices are clearer, so grain sale timing, input prepayments and machinery purchases can be coordinated.
Does deferring crop insurance help?
If you normally sell your crop in the following year, you may be able to elect to report crop insurance proceeds received for a damaged crop in the following year instead.
How can I transfer farmland to my children?
Common options include gifts, instalment sales, leases and holding land until death. Each has different tax effects, so plans should be made with your attorney.
Should I make purchases before July 2027?
The state rate increase is 0.3 percentage points. For large purchases this can be worth considering, but business needs should come first.
Talk to BOMCAS About Tax Planning in Aberdeen
Plans start from accurate books, filed business returns and current personal returns. Owner pay is put into effect through payroll, and equipment or building purchases affect sales and use tax. If earlier years are still open, clear the backlog first, and review cross-border tax before any move or investment involving Canada. Across South Dakota, we also explain business returns, personal returns, sales tax, bookkeeping, payroll, back taxes and Canada–U.S. tax on our state pages, which start from the South Dakota overview.
