Crypto staking and DeFi tax simulator

This English page translates the Korean virtual-asset staking and DeFi tax guide, preserving other-income, interest-income, business-income, withholding, basic deduction, and CARF-style risk logic.

Income classification

Staking, LP rewards, royalties, airdrops, hard forks, and lending can be classified differently. The model distinguishes other income at 22 percent, interest income at 15.4 percent, business income under progressive rates, and capital-gains style sale gains.

The simulator keeps the KRW 2.5 million basic deduction for the relevant virtual-asset gain logic and allows loss offset where the Korean model permits it. Gas fees and sale proceeds are tracked separately from receipt value.

Resident and non-resident cases

Residents are evaluated with other comprehensive income and potential business-income treatment. Non-residents can be shown with 22 percent withholding, which changes both cash flow and reporting posture.

Business judgment uses activity indicators such as daily trading frequency, automated bots, marketing activity, and full-time activity. A higher score can move the result from other-income style reporting toward business-income review.

Risk flags

The output includes total receipt value, sale amount, gas fees, capital gains, taxable base, receipt tax, capital-gains tax, interest tax, business-income tax, local tax, total tax, and net profit.

Use this page as a documentation checklist before reporting staking or DeFi income. Exchange type, wallet history, receipt-date fair value, gas fees, sale proceeds, and CARF-style cross-border information can all affect the final file.
