Iowa
Reviewed July 2026Federal §453 conformity
Yes — Iowa starts from the federal return and taxes installment gain as payments arrive at a flat 3.8%, the end point of one of the fastest rate descents in the country (Iowa's top rate was 8.53% as recently as 2022). For retiring farmers, the rate may not matter at all: Iowa offers a lifetime election that can exclude the gain from selling farmland from Iowa tax entirely — the state's single most valuable provision for this site's readers, covered below.
Nonresident sourcing
Gain from Iowa real estate or a business operating in Iowa is Iowa income for sellers anywhere — a rule that reaches far in a state where so much farmland is owned by heirs who moved away. The payments keep that character; intangible gain generally follows the seller home.
Withholding
Iowa imposes no closing-table withholding on nonresident real estate sellers. What Iowa does instead — and did earlier and more firmly than most states — is make the pass-through entity itself responsible: composite returns for nonresident owners are mandatory, so the entity files and pays Iowa tax on their shares each year payments are recognized, unless the PTE election covers the same ground.
Selling, then moving (residency change)
Iowa-source gain stays taxable here after a move; other gain travels with the seller, and no rule accelerates deferred gain at the border. At 3.8% flat — and possibly zero under the farmer election — Iowa is rarely the state anyone flees for tax reasons, and the retired-farmer provisions reward staying put through the sale.
Pass-through entity (PTE) tax election
Iowa's PTE election arrived in 2023 with retroactive reach and runs at the top individual rate — now just 3.8% — with owner credits. The modest rate cuts both ways: the entity-level dollars are small, but so is the cost of capturing the federal deduction. It coordinates with Iowa's mandatory composite regime rather than replacing it, so the entity's Iowa filings need one coherent plan per payment year, not two defaults colliding.
Estate and IRD
Iowa finished repealing its inheritance tax — transfers in 2025 and later owe none — and it has no estate tax, so the note passes with no Iowa layer at death. The federal rules apply as everywhere: heirs pay income tax as payments arrive, with no basis step-up in the deferred gain.
Planning notes
Iowa planning centers on one decision made once: the retired farmer election. A farmer who is 55 or older (or disabled), materially participated in farming for ten years, and held the property ten years can make a single lifetime election to exclude the capital gain from selling farmland — which, made in the sale year, shelters the installment payments as they arrive. The same lifetime slot can instead be used to exclude farm lease income, so a retiring farmer choosing between selling and renting is really choosing where to spend the one election. It cannot be undone, and it should not be made — or wasted — casually.
Iowa's retired farmer provision excludes qualifying farmland sale gain from Iowa tax — including the installment payments as they arrive — but it is a single, irrevocable lifetime election, and the same slot can alternatively exclude farm lease income. A retiring farmer weighing sale against rental is choosing where the one election does the most work over a lifetime, not just in year one.
Iowa requires pass-through entities to file composite returns and pay tax for nonresident owners — every year the entity recognizes installment gain. Coordinate the composite obligation with any PTE election up front, or the entity's Iowa compliance runs on two colliding defaults for the life of the note.
