Mississippi
Reviewed July 2026Federal §453 conformity
Yes — Mississippi starts from federal concepts and taxes installment gain as payments arrive at a flat 4% for 2026, the endpoint of the 2022 phase-down — and the story doesn't stop there: 2025 legislation enacted further cuts beginning in 2027, with revenue triggers aimed at eliminating the income tax entirely over time. That gives the installment structure a quietly favorable tilt here: gain pushed into later years meets a lower rate, and possibly no rate at all. The honest caveat travels with it — the elimination path is contingent on growth triggers, so model the enacted schedule, not the aspiration.
Nonresident sourcing
Gain from Mississippi real estate or a business operating in Mississippi is Mississippi income for sellers anywhere, and the payments keep that character; intangible gain generally follows the seller home.
Withholding
Mississippi imposes no closing-table withholding on nonresident real estate sellers. Pass-throughs handle nonresident owners through withholding or composite filings each recognition year unless the PTE election covers it.
Selling, then moving (residency change)
Mississippi-source gain stays taxable here after a move (at whatever rate the schedule has fallen to); other gain travels with the seller, and no rule accelerates deferred gain at the border.
Pass-through entity (PTE) tax election
Mississippi's PTE election taxes the entity at the individual rate with owner credits, on annual terms. The falling rate cuts the election's value each year alongside the tax it offsets — re-model annually rather than carrying assumptions across the stream.
Estate and IRD
Mississippi has no estate or inheritance tax. At death the federal rules apply — heirs pay income tax as payments arrive — with no state layer, and at rates that may be lower still by the time later payments reach them.
Planning notes
Mississippi's list: carry the rate as a declining variable in every projection — the enacted schedule, with the trigger-contingent tail marked as such; re-model the PTE election annually; and let the structure's natural deferral do what it does especially well here, pushing gain toward cheaper years.
Mississippi's flat rate is 4% for 2026, with enacted cuts from 2027 and growth triggers aimed at full elimination. An installment stream pushes gain into progressively cheaper years — a structural tailwind for deferral here — but the elimination tail is trigger-contingent, so model the enacted schedule and label the rest.
