Canadian Connections in the Capital
Pierre's Canadian connections tend to be individual: a Canadian-trained nurse or physician at the hospital, an engineer or scientist in a state agency, a family that bought a cabin or hunting land near Lake Oahe, or an outfitter whose regular clients drive down from the Prairie provinces. Each case touches both tax systems. BOMCAS is based in Edmonton and prepares returns in both countries.
For treaty and residency basics, see our South Dakota cross-border tax page. This page applies them to Canadians working, owning property or booking trips in Pierre.
Canadian Professionals Working Here
Canadians who come to Pierre on TN status or a work visa usually become U.S. residents for tax purposes once they meet the substantial presence test, and they must also decide how and when to end Canadian residency. The year of the move can involve a Canadian departure return, deemed disposition of certain assets and a U.S. dual-status or full-year resident return. RRSPs and RRIFs can generally continue to grow tax-deferred under the treaty, while TFSAs are not recognised by the U.S. and need separate reporting.
State and Public Pensions
Canadians who once worked in Canada and now work in Pierre may later receive Canada Pension Plan and Old Age Security alongside an SDRS pension and U.S. social security. Under the treaty, CPP and OAS paid to a U.S. resident are taxed as if they were U.S. social security. The Windfall Elimination Provision, which once reduced U.S. social security for people with foreign pensions, was repealed for benefits payable after December 2023.
Canadians Owning Property Here
Canadian residents who own a cabin, house or hunting land near Pierre and rent it out file Form 1040-NR and can elect to be taxed on net rental income. Leasing land for grazing or hunting is also U.S. rental income. When the property is sold, FIRPTA withholding usually applies, and the sale is reported in Canada with a credit for U.S. tax. The property may need to appear on Form T1135 if it is held for rental.
Outfitters with Canadian Clients
A Pierre lodge or guide selling trips to Canadians charges South Dakota sales and tourism tax as usual, since the service is provided here. Taking deposits in Canadian dollars or through Canadian payment platforms creates currency gains and losses that should be recorded in the books.
Former Canadians and Dual Citizens
Dual citizens and former Canadians in Pierre with Canadian bank accounts, RRSPs or inherited property file an FBAR when accounts total more than $10,000 and may need Form 8938. Inheriting property from a Canadian parent usually means a Canadian estate return as well as U.S. reporting of the gift or inheritance.
Canadian Visitors on Long Trips
Canadians who spend a large part of the year fishing or hunting in the Pierre area should keep track of their days. Under the substantial presence test, a weighted total of 183 days over three years can make a visitor a U.S. tax resident unless they file Form 8840 to show a closer connection to Canada. Owners of lake property who visit often are the most likely to reach that total.
Canadian Spouses and Mixed Households
When one spouse is a U.S. citizen and the other is Canadian, the couple can often elect to file jointly in the U.S. by treating the Canadian spouse as a U.S. resident, which may lower the tax but brings that spouse's worldwide income into the U.S. return. We compare joint and separate filing before choosing.

Pierre Cross-Border Tax Questions
I am a Canadian nurse on TN status in Pierre. Where do I file?
Usually a U.S. resident return once you meet the substantial presence test, plus a Canadian return for the year you leave Canada.
Will CPP reduce my U.S. social security?
The Windfall Elimination Provision was repealed for benefits payable after December 2023, so CPP no longer reduces U.S. social security under that rule.
I live in Canada and lease my land near Pierre to hunters. Is that taxable in the U.S.?
Yes. It is U.S. rental income, usually reported on Form 1040-NR.
Do I need an FBAR for my Canadian RRSP?
RRSPs count as foreign financial accounts for FBAR purposes, so they are included in the $10,000 test.
Talk to BOMCAS About Cross-Border Tax in Pierre
The U.S. filing may be a personal return or a business return. Canadian owners renting a cabin need sales tax registration, and a new U.S. business needs bookkeeping and payroll. Plan before moving, and use late filing for missed years. For work elsewhere in the state, we keep South Dakota pages on business tax returns, personal tax, sales and use tax, bookkeeping, payroll, tax planning and back taxes, linked from the South Dakota overview.
