Dividend Increase and Financial Income Composite Tax, Procedure and Key Checks

TL;DR

• When dividends rise, you must sum annual financial income (interest and dividends) to judge composite tax applicability.
• Proceed through the four steps of calculation, document collection, payment and filing. Confirm current rates and thresholds with your broker or the tax office.

1. Basic flow of financial income composite tax

Dividend income is classified with interest as financial income. If annual financial income exceeds a threshold, it is aggregated into total taxable income and becomes subject to composite taxation. Thresholds and rates can change, so confirm the latest standards with your broker or the tax authority.

2. Step-by-step procedure (for beginners)

1) Sum annual financial income

• Check annual dividend and interest records across all accounts. Year-end payment statements from brokers or banks are convenient.

2) Check withholding tax

• Withholding tax is applied when dividends are paid. Organize withholding amounts and net receipts to reflect in total income.

3) Determine composite tax applicability

• Verify whether the summed financial income exceeds the applicable threshold. Confirm the current threshold, as it can change.

4) Prepare for filing and payment

• If subject to composite taxation, attach financial income documents when filing your personal income tax return. Prepare transaction statements and withholding tax receipts as evidence.

3. Filing cautions and checklist

• Prevent omissions: take care not to omit dividends received from multiple brokers or accounts.
• Foreign dividends and stock dividends: dividends received in kind may be taxed differently, so check specific rules.
• Aggregation period: aggregation is typically done on a calendar year basis, so review your records before and after year-end settlement.

4. Practical tips and recommendation to consult

• Use automation tools: organizing year-end statements and transaction records in Excel makes assessment easier. Check dividend records with tools like 내 종목 레이더.
• Consult a professional: results can vary depending on individual circumstances, including business income and other income, so consult a tax accountant or your broker's customer service.
