How & when to claim
- ›Employees: claimed via year-end tax settlement (usually Jan–Feb of the following year) under the marriage tax credit line.
⚠️ Please note
- · A tax credit only helps if you owe tax (computed tax). A spouse with no income gets ₩0.
- · This is a once-in-a-lifetime credit. You cannot claim it again even after a remarriage.
- · Only marriages registered by 2026-12-31 qualify; registrations in 2027 or later are not eligible under current rules.
- · The credit reduces tax you owe within your computed tax; it is not refunded beyond the tax you actually owe.
