Spousal Deductions Apply Regardless of Nationality
Once you've legally registered your marriage, you're recognized as a spouse under Korean tax law regardless of nationality, and you can claim spousal deductions on gifts and inheritance. That said, how it actually applies can vary depending on your residency status and the documents proving your marriage, so it's worth confirming in advance.

Tax Advantages for Marriage Immigrants
The spousal deduction limit is far higher than other relationships
Compared to the deduction for lineal relatives (50 million KRW) or other relatives (10 million KRW), the spousal gift deduction (600 million KRW) is far larger, leaving significant room to save on tax if you plan the timing and amount of any transfer in advance.
The marriage/childbirth gift deduction helps with settling-in costs
The marriage/childbirth gift deduction introduced in 2024 can further reduce the tax burden on money received from parents to help you settle in.
Planning gifts ahead of time helps manage your inheritance deduction limit
Gifts made to a spouse within 10 years before an inheritance reduce the inheritance deduction limit, so it pays to think through your long-term wealth transfer plan in advance.
The Most Common Mistake We See
People often don't realize gifts are combined over a 10-year period and end up owing tax on the excess after splitting gifts into several transfers, or they're unaware that gifts made before an inheritance reduce the inheritance deduction limit and end up owing more tax than expected.
