Talk to a South Dakota investment advisor
Share a few details and an advisor who works with South Dakota investors will reach out to talk through your goals, free.
Free, private and no obligation
An investment advisor picks and manages the stocks, bonds and funds in your accounts, and may also help with taxes and goals. In South Dakota there is no state tax on dividends, interest or capital gains, so after-tax returns depend on federal rules and on what you pay in fees. Many families already hold a lot in land and a business, so a good portfolio spreads risk away from the farm instead of adding to it.
Key takeaways for South Dakota
- South Dakota has no personal income tax, so interest, dividends and capital gains are not taxed by the state.
- Fees matter: a one percent annual charge on $500,000 is $5,000 a year, so compare the total cost in dollars.
- Many South Dakota households already hold most of their wealth in land or a business, so a portfolio should spread risk.
- Registered investment advisors and many brokers are registered with the Division of Securities or the SEC.
- Fraud targets rural and older investors, so verify anyone who calls with an offer.
What an investment advisor does
An investment advisor recommends or manages investments for a fee. Some build a portfolio, watch it, rebalance it and handle tax-aware trading. Others give advice that you carry out yourself. The word advisor is used loosely, so the first step is learning exactly what a person is licensed to do and whether they are legally required to put your interests first when they advise you.
According to the U.S. Census Bureau, 2020 to 2024 American Community Survey, South Dakota’s per capita income is about $40,550, the median household income is about $75,081 and about 31.9 percent of adults have a bachelor’s degree or higher. Unemployment is about 2.9 percent. Many households have the capacity to invest beyond the retirement plan at work, and the right guidance can make a gap of tens of thousands of dollars over a career.
| Role | What it usually means |
|---|---|
| Registered investment adviser | A firm or person registered with the state or the SEC to give advice for pay |
| Broker-dealer representative | A person who sells securities and is paid by commission or fees |
| Dually registered | Someone who can act in both roles |
| Robo-advisor | An online service that builds portfolios from a questionnaire |
Fiduciary and suitability
A registered investment adviser owes a fiduciary duty to clients under the law, meaning a duty of care and loyalty. A broker making a recommendation to a retail customer must act in the customer’s interest ahead of their own under a federal rule, but the standard and the conflicts differ. Ask each person in writing whether they act as a fiduciary on all of your accounts, and how they are paid. Our investing guide explains the building blocks, such as stocks, bonds and index funds.

Taxes on investments in South Dakota
The state has no tax on wages, interest, dividends or capital gains for individuals. This does not make investing tax free, because federal tax still applies and varies with the type of account. Interest is taxed as ordinary income, qualified dividends and long-term gains at lower rates, and gains in an IRA or 401(k) grow without yearly tax. A good advisor places investments in the right accounts: bonds in tax-deferred accounts, broad stock funds in taxable accounts, and high-growth assets in a Roth. Selling a holding in a brokerage account can create a gain, so ask how trades will affect your taxes. Confirm current rules with a tax professional.
Concentrated risk: land, farms and a local bank
A South Dakota household often owns many assets that depend on the same thing. A farmer holds land, equipment and crops that all rise and fall with commodity prices and weather. A rancher’s income depends on cattle prices, hay and rain. A Sioux Falls employee may own stock in the bank or health system that pays the salary. Putting the rest of your money into the same sector adds to that risk. A portfolio of broad funds held outside the business, spread across companies and countries, can balance it. An advisor should ask what you already own before suggesting anything new.
Farm money and uneven income
A good harvest or a sale of calves can bring a large deposit in one month. Without a plan it sits in a checking account or goes toward equipment to reduce taxes. An advisor can help set up a tax-aware pattern: pay down expensive debt, fund a SEP IRA or solo 401(k), hold an operating reserve, and invest the rest for the long run. Bad years happen, so avoid investments that need to be sold at a loss when cash is tight. A cattle producer near Belle Fourche who sold calves in the fall might set aside part for estimated tax, part for next spring’s costs and part for a diversified fund held for ten years or more.

Rural investors and fraud
Older and rural investors are often targeted by scams: unsolicited calls, promises of high returns with no risk, pressure to act today, or a request to move money into crypto, a private note or a fake account. The Division of Securities offers investor education and takes complaints, and the SEC and FINRA also provide alerts. Before you invest, look up the person and the product, ask for written details, and take time. If a deal sounds too good to be true, it usually is. Never share passwords or one-time codes with a caller. Family members can also help by agreeing on a trusted contact person for the account.
Public employees and the pension
Members of the South Dakota Retirement System receive a pension and may have a variable retirement option. These are part of your investment picture, because a pension acts like a large bond that pays you for life. An advisor may suggest holding a little more in stocks in your other accounts for that reason, or fewer if you want to be cautious. Teachers and county workers can also contribute to a 403(b) or 457 plan. Ask for the fees on those accounts, and compare them with low-cost index funds.
Building a portfolio
Most portfolios mix stocks for growth and bonds for stability. The split depends on your age, goals and temperament. A 35-year-old saving for retirement in 30 years can hold mostly stocks, while a 66-year-old who needs to draw money in a few years holds more bonds and cash. Low-cost index funds and exchange-traded funds are the core for many investors. An advisor adds value by setting the mix, rebalancing, managing taxes and keeping you from selling in a panic. Ask to see the funds in your portfolio and the expense ratio of each.
Saving for school
South Dakota’s CollegeAccess 529 plan lets savings grow tax deferred, and withdrawals for qualified costs are tax free federally. Since the state has no income tax, there is no state deduction, so compare plan fees and investment choices with other states. Our college savings guide explains the choices and the age-based portfolios.
What investment advice costs
A common fee is a percentage of assets, often around one percent a year, with lower rates at higher balances. Some firms charge a flat annual fee, a monthly subscription or an hourly rate. Funds carry their own expenses on top of the advisor’s charge. On $500,000, one percent is $5,000, and a fund with a 0.50 percent expense ratio adds $2,500. Ask for a written summary of every cost in dollars, and ask what services you receive for the advisor’s fee.
How to check and choose an advisor
- Search the SEC adviser database. It lists registered firms, their Form ADV and any discipline.
- Use FINRA BrokerCheck. It shows brokers’ histories, licenses and complaints.
- Contact the Division of Securities. It can confirm state registration.
- Ask about custody. Your assets should be held at an independent custodian in your name.
- Ask how performance is reported. Look for clear comparisons to a plain benchmark.
- Compare at least two. Prices and approaches differ.

A worked example from Sioux Falls
Consider a couple, ages 45 and 43, who both work in healthcare in Sioux Falls and earn $150,000 together. They have $320,000 across two 401(k) plans, $40,000 in a savings account and a 529 for each of two children. Their advisor starts by listing every fund and its cost, and finds one plan with an expense ratio near one percent while the other offers index funds near 0.05 percent. The advisor suggests directing new savings to the cheaper plan up to the employer match, moving idle cash into a short-term bond fund beyond a six-month reserve, and rebalancing to a mix of about 70 percent stocks and 30 percent bonds. None of this is exotic. The value comes from lower costs, steady contributions and a plan that is followed through a market drop.
Behavior and staying the course
Studies of investors repeatedly show that the biggest damage often comes from selling after a decline and buying back after a recovery. A South Dakota farm family that watched grain prices swing knows the feeling in a different market. An advisor helps by writing an investment policy in advance: the target mix, the rebalancing rule and what you will do when stocks fall by a quarter. When the day arrives, you follow the paper instead of the headlines. Our retirement planning guide explains why the first years of retirement are sensitive to this.
Rental property and real estate
Some South Dakotans invest in rental homes near the universities in Brookings and Vermillion, duplexes in Sioux Falls or a hunting lodge in the central part of the state. Rentals can produce income, and they also bring vacancy, repairs, insurance and landlord duties. They add to local concentration. An advisor can estimate your real return after costs and show how much of your wealth sits in one county. If you are thinking of selling a rental, ask about the federal tax on gains and about a like-kind exchange, and see our financial advisors guide for who can help with each part.
Income and values-based portfolios
Retirees often want regular income from dividends and interest, while others ask for portfolios that avoid certain industries or favor others. These choices are available, though they can carry higher fees or narrower diversification. Ask how a strategy is built, what it holds and what it costs, and compare the result with a plain index portfolio. A church or ranching family may also prefer to limit foreign holdings or fossil fuel exposure, and a good advisor will explain the tradeoffs without pressure.
When to review your investments
Check in at least once a year, and again after a big change: a job move, a sale of land, an inheritance, a new child or a health event. At each review ask four things. Did the mix drift from the target? Did fees change? Do the goals and time horizon still match? Did the tax picture shift? A short written summary after each meeting helps you remember what was decided and why. If you are not hearing from your advisor, or you cannot get a straight answer on cost, that is a sign to look elsewhere.
