Sioux Falls Business Owner: S-Corp + Cash Balance Plan
A financial advisory firm owner in Sioux Falls has $480K of net business income. An S-Corp election with a documented reasonable salary moves the profit above that salary out of self-employment tax, though the Social Security piece already stops at the wage base. A cash balance plan paired with a 401(k), sized from the W-2 salary and the owner's age, can create a large deduction, but it must cover eligible staff and needs steady annual funding. South Dakota has no personal or corporate income tax, so the benefit is federal only.
Multi-Generational Farm: Estate & Succession Planning
A family running a 5,000-acre farming operation near Mitchell plans to pass the land and equipment to the next generation. South Dakota has no estate or inheritance tax, so the exposure is federal, and the higher federal exemption under 2025 law covers many farm families but not every large operation. Common tools include a family limited partnership or LLC, annual exclusion gifts, grantor retained annuity trusts, special use valuation for farmland under Section 2032A, and estate tax deferral under Section 6166.
California Owner: South Dakota Trust Situs
A California business owner considers a South Dakota trust to hold investment assets. South Dakota has no income tax on trust earnings and allows perpetual trusts. Moving the situs does not end California tax by itself: California taxes trust income based on where trustees and noncontingent beneficiaries live, taxes a grantor trust's income to the California grantor, and treats incomplete-gift nongrantor (ING) trusts as grantor trusts. Gift tax, grantor status, and distribution planning have to be worked out alongside the state result.
