Language does not determine your tax rate
This tool was originally designed to compare Korean regular investment accounts holding Korean- and US-listed ETFs. The English interface uses USD as the reporting currency. It does not convert the calculator into a US resident tax return tool.
The sample 15.4% rate is an illustrative Korean withholding assumption. The 15% sample shown for US-listed holdings refers to ordinary dividend withholding under the Korea–US treaty for eligible investors. Neither sample applies universally. Payment character, treaty eligibility, account type and individual circumstances require separate confirmation.
How the estimate works
Estimated net dividends = gross dividends − estimated tax
With USD 100 gross, a 15.4% rate and a 100% taxable portion, estimated tax is USD 15.40 and net income is USD 84.60. If you instead assume only 60% is taxable, the estimate becomes USD 9.24 tax and USD 90.76 net. The 60% example is a user assumption, not a rule for any named ETF.
Each holding can have different assumptions
The first goal form controls the hypothetical capital calculation and reinvestment simulation. Each holding has its own editable tax rate and taxable portion. Changing the goal tax rate does not overwrite existing holdings.
For Korean-listed foreign-asset ETFs, actual taxable bases and foreign tax adjustments can make a single rate applied to all cash distributions misleading. Compare your assumptions with official provider information and brokerage withholding records. Do not deduct tax twice by entering an already-net distribution as a gross amount.
What is excluded
The calculator does not reproduce comprehensive income taxation, deductions, foreign tax credits, ISA or pension account treatment, or a final tax filing. It also excludes transaction fees. If you cannot represent the actual treatment with a simple rate and taxable portion, treat this result as a limited scenario rather than your expected account balance.
