Rental business registration benefit calculator

This English page follows the Korean registered-vs-unregistered rental business analysis across income tax, property tax, capital-gains tax, acquisition tax, property-tax reduction, obligation costs, and health insurance.

Income tax benefit

The income-tax comparison uses rental revenue from monthly rent and deemed rent. Registered cases can receive a higher expense rate and tax reduction, while unregistered cases use the lower expense treatment in the source model.

For housing rental revenue up to KRW 20 million, the model compares separate tax and comprehensive tax. The registered case can apply the reduction rate by registration type and rental unit count.

Property and capital-gains effects

The calculator checks whether registered rental housing can be excluded from comprehensive real-estate tax. Conditions include standard-price limits, adjusted-area acquisition restrictions, and floor-area treatment.

Capital-gains tax comparison uses long-term holding special deduction logic for registered rental housing and compares it with the unregistered deduction. The model also accounts for multi-house surcharge in adjusted areas when applicable.

Costs and recommendation

Registration can also create obligation costs, including guarantee insurance and annual administrative cost. The source model compares benefits over the required obligation period and subtracts those costs.

The recommendation is not automatic tax advice. It depends on whether the landlord can satisfy rent-increase limits, registration period, insurance obligations, future sale plan, and local government registration rules.
