OVERVIEW
South Dakota and North Carolina share an unusual feature among the states: both are on paths toward zero income tax — but South Dakota has been there since 1889 (constitutionally protected) while North Carolina is on a legislative glide path, reducing from 3.99% toward 0% by 2037. Today, South Dakota holds a clear income tax advantage: $0 vs North Carolina's 3.99% flat rate. At $100,000 income, that's approximately $3,990/year in savings for South Dakota. However, North Carolina's property tax (~0.82%) is below South Dakota's (~1.14%), which partially narrows the gap. North Carolina's combined sales tax (~6.98%) is also above South Dakota's (~6.4%). As North Carolina's income tax phases down toward 0%, the income tax comparison between these two states will eventually equalise — making the long-term differentiators property tax, sales tax, and lifestyle. For trust planning, South Dakota remains in a class of its own regardless of income tax rate. For today's high earners choosing between these states, South Dakota offers the immediate complete income tax exemption; North Carolina offers the Research Triangle's booming technology and research economy with a tax trajectory converging toward South Dakota's position.

South Dakota Pros & Cons

+ PROS
  • No income tax today — South Dakota constitutionally prohibits income tax; residents pay $0 now; North Carolina's 3.99% rate means a $100K earner pays approximately $3,990/year in state income tax while a South Dakota resident pays nothing
  • Nation's premier trust jurisdiction — South Dakota's trust laws are unmatched; dynasty trusts, DAPTs, directed trust legislation, and privacy protections support over $600B in domiciled trust assets; North Carolina has standard trust laws and no comparable infrastructure
  • No capital gains tax — South Dakota charges $0; North Carolina taxes gains at 3.99% flat; a $500,000 gain saves approximately $19,950 in state tax today (shrinking as NC rate phases down)
  • Slightly lower combined sales tax — South Dakota's combined average (~6.4%) is below North Carolina's (~6.98%); on $30,000/year of taxable spending, SD saves approximately $174/year
  • Constitutionally protected — South Dakota's no-income-tax status is enshrined in its constitution and cannot be changed without a statewide vote; North Carolina's 0% target is legislative and subject to revenue triggers
− CONS
  • Higher property tax than North Carolina — South Dakota's ~1.14% exceeds North Carolina's ~0.82%; on a $400,000 home, SD pays approximately $1,280/year more in property tax; this narrows the net income tax advantage at lower income levels
  • North Carolina's advantage is temporary and closing — NC's income tax is scheduled to reach 0% by 2037; at that point, the income tax comparison equalises and South Dakota's only advantages are trust law and constitutional protection
  • Limited career ecosystem vs Research Triangle — Raleigh-Durham's technology, university, and biotech ecosystem far exceeds what Sioux Falls or Rapid City can offer; South Dakota lacks the professional density of North Carolina's major metros
🌲

North Carolina Pros & Cons

+ PROS
  • Research Triangle career ecosystem — Raleigh-Durham is home to Apple, Google, Amazon, Lenovo, Duke, UNC, and NC State; one of the most dynamic technology and biotech clusters in the US; vastly exceeds South Dakota's career opportunities
  • Income tax is declining rapidly toward zero — North Carolina's rate has fallen from 5.25% (2022) to 3.99% (2025) and is scheduled to reach 0% by 2037; NC is actively becoming a no-income-tax state; residents today are buying into a state converging toward South Dakota's tax position
  • Lower property tax — North Carolina's ~0.82% is below South Dakota's ~1.14%; for homeowners with high-value properties, this partially offsets NC's income tax disadvantage
  • Mild climate and coastal/mountain access — North Carolina's four-season climate, Outer Banks beaches, and Blue Ridge mountains offer lifestyle diversity that South Dakota's plains climate cannot match
− CONS
  • 3.99% income tax today — North Carolina residents pay 3.99% on wages, investment income, and retirement distributions; South Dakota residents pay $0; at $200,000, approximately $7,980/year difference today
  • Capital gains taxed as ordinary income — North Carolina taxes all capital gains at 3.99% flat; South Dakota charges $0; a $500,000 gain costs approximately $19,950 in North Carolina state tax today
  • Higher combined sales tax — North Carolina's ~6.98% exceeds South Dakota's ~6.4%; on $30,000/year of spending, approximately $174/year more
  • No trust law advantage — North Carolina's trust laws are standard; South Dakota's trust planning infrastructure is irreplaceable for dynasty trusts, DAPTs, and privacy-sensitive structures
FAQ

Frequently Asked Questions

Does South Dakota have an income tax?

No. South Dakota's state constitution has prohibited a personal income tax since statehood in 1889. Residents pay $0 state tax on wages, salaries, investment income, capital gains, and retirement distributions. This constitutional protection cannot be changed without a statewide vote, making South Dakota's no-income-tax status among the most permanently protected in the US.

Is North Carolina eliminating its income tax?

Yes, under current legislation. North Carolina's income tax has fallen from 5.25% in 2022 to 3.99% in 2025, with scheduled reductions to 3.49% in 2026, 2.99% in 2027, 2.49% in 2028–2029, and ultimately 0% by 2037, subject to annual revenue triggers. South Dakota already has 0% income tax today. Residents choosing between these states now benefit from South Dakota's full income tax advantage — but that advantage narrows every year as North Carolina's rate phases down.

How much does a North Carolina resident save by moving to South Dakota?

At $100,000 income: approximately $3,990 income tax saving minus ~$960 additional property tax plus ~$174 sales tax saving = approximately $3,204 net annual advantage for South Dakota. At $200,000: approximately $6,612 net. At $300,000: approximately $10,020 net. For capital gains: a $500,000 gain saves approximately $19,950 today. These savings narrow each year as North Carolina's income tax rate phases down toward 0%.

How do property taxes compare between South Dakota and North Carolina?

South Dakota's effective property tax rate averages approximately 1.14% vs North Carolina's approximately 0.82%. On a $400,000 home: South Dakota costs approximately $4,560/year; North Carolina approximately $3,280/year — a difference of approximately $1,280/year. This property tax differential partially offsets South Dakota's income tax advantage, particularly at lower income levels.

Is South Dakota better than North Carolina for trust planning?

Yes, significantly. South Dakota offers trust law advantages that North Carolina cannot match: no rule against perpetuities (dynasty trusts indefinitely), Domestic Asset Protection Trusts with strong creditor protection, directed trust legislation, and trust privacy protections. No state income tax on trust income held in South Dakota trusts. Over $600B in trust assets are domiciled in South Dakota. North Carolina's trust laws are conventional and do not offer these advanced planning tools. Even if North Carolina reaches 0% income tax by 2037, South Dakota's trust law superiority will remain.

Does North Carolina have a capital gains tax?

Yes. North Carolina taxes capital gains as ordinary income at the flat 3.99% rate. There is no preferential rate for long-term capital gains. A South Dakota resident selling $500,000 in stock pays $0 state capital gains tax. A North Carolina resident pays approximately $19,950. As North Carolina's income tax rate phases down toward 0%, the capital gains tax savings of choosing South Dakota over North Carolina will diminish accordingly.
