Idaho LLC structure and cost: a flat 5.3% income tax, no franchise tax, and no transfer tax, one of the lowest-friction states to hold property

Idaho is one of the lowest-friction states in the country for holding real estate, and the reasons stack up cleanly. It taxes LLC income at a flat 5.3%, the same rate for individuals and corporations. It charges no franchise tax and no gross-receipts tax. And it imposes no real estate transfer tax, so moving a property into an Idaho LLC costs nothing at the courthouse. Add a free annual report, and the running cost of an Idaho structure is close to the floor. The one gap is structural: Idaho has no series LLC, so an investor holding several properties uses a separate LLC for each. Take the tax picture first.

The flat tax and the missing frictions

Start with the rate, which is flat and recently cut.

Idaho taxes LLC income at a flat 5.3%, the same rate for individuals and corporations, with no franchise or gross-receipts tax on top.

A standard Idaho LLC is a pass-through, so its income lands on the members’ returns at Idaho’s flat 5.3% rate, which the legislature cut from 5.695% effective in 2025 and which applies equally to individual and corporate income. There is no franchise tax, no gross-receipts tax, and no separate capital-gains surcharge, so the 5.3% is essentially the whole state income-tax story, which is why the Tax Foundation ranks Idaho near the top of its competitiveness index. The sales tax is 6%, with a local resort-city tax of up to 3% in tourism towns like Sun Valley and McCall. For an investor, the flat, moderate income tax with nothing layered on top is easy to model and low by regional standards. The absence of a transfer tax compounds the advantage.

Idaho has no real estate transfer tax, so moving property into an Idaho LLC costs nothing beyond recording.

Idaho imposes no deed transfer or stamp tax, so retitling a property into an Idaho LLC costs only the ordinary recording fee, which removes the friction that a transfer-tax state puts on moving property into a protective entity. Combined with the flat income tax, no franchise tax, and the free annual report on the filing page, that makes Idaho one of the cheapest states to both acquire and hold property in an LLC. The one thing Idaho does not give an investor is a series.

No series, so separate LLCs

Idaho’s structural gap is the series, though its low costs soften the impact.

Idaho has no series LLC, so an investor holding several properties forms a separate LLC for each.

Idaho’s LLC act has no series provisions, so the single-entity-with-cells structure available in Iowa or Kansas does not exist here, and each property an investor wants insulated goes in its own LLC. The series LLC guide covers the form Idaho lacks. Here is where Idaho’s low costs matter: because the annual report is free and there is no franchise tax, running several separate Idaho LLCs is inexpensive, so the absence of a series is less costly than it would be in a state that charges a per-entity fee every year. An investor with ten Idaho properties forms ten LLCs and pays no annual state fee for any of them, which is a very different picture from Arkansas, where each entity carries a flat $150 franchise tax. So Idaho trades the convenience of a series for genuinely low per-entity cost, and for many investors that is an acceptable trade. The discipline the structure requires is on the filing side, because the free report is easy to forget.

The bottom line

Idaho taxes LLC income at a flat 5.3%, the same for individuals and corporations, cut from 5.695% in 2025.

Idaho has no franchise tax and no gross-receipts tax, so the 5.3% is essentially the whole state income-tax story.

Idaho has no real estate transfer tax, so moving property into an Idaho LLC costs nothing beyond recording.

Idaho has no series LLC, so multiple properties mean multiple separate LLCs, though the free annual report keeps the per-entity cost near zero.

The combination of a flat low tax, no franchise tax, no transfer tax, and a free report makes Idaho one of the lowest-friction states to hold property.
