Different donation types get different credit rates. Political donations get a 100/110 credit up to KRW 100,000 and 15% above that (25% above KRW 30 million). Statutory donations, employee stock ownership association donations, and designated (general) donations get 15% (30% for the portion over KRW 10 million).
Donations to religious organizations are classified as designated donations but are capped separately at 10% of wage income (versus 30% for other designated donations, or 100% for statutory donations).

Excess donations aren't wasted
Donations exceeding the cap for a given year don't disappear — they can be carried forward for up to 10 years. If you've made large donations over several years, check each year that the carried-forward amount is correctly reflected in your Hometax donation records.
