Work through each spouse's income, the child requirements, household property, and duplicate filings in order to make sense of the final amount
Having two incomes in a household doesn't by itself determine household type or the outcome of a tax credit application. What matters first is each spouse's individual total wage income, checked separately from the household's combined total income and combined property.
This list is organized in the order a couple can realistically split up the work: income, then children, then property, then application history. Note that this guidance reflects the 2025โ2026 rules and may change โ online calculators only give reference figures, so confirm the final numbers through Korea's National Tax Service Hometax portal or your local tax office.
