How do tax treaties reduce withholding tax?

Tax treaties between countries typically reduce the domestic withholding tax rate on cross-border payments. For example, the US domestic rate for dividends is 30%, but under the US-UK treaty it is reduced to 15% (5% for substantial holdings). The reduced rate applies only to residents qualifying under the treaty.

What is a Limitation on Benefits (LOB) clause?

An LOB clause prevents treaty shopping by requiring the taxpayer to satisfy objective tests (publicly traded, ownership/base erosion, active trade/business, or derivative benefit tests) to claim treaty benefits. US treaties typically include stringent LOB provisions following the OECD BEPS Action 6 recommendations.

time — Number of periods (years, months, or days) over which the calculation runs.
jurisdiction — Country, tax year, filing status, or regional rules that adjust the calculation.
Result — Computed amount: total, liability, return, repayment, or present/future value.

Note: Financial results are estimates and depend on the accuracy of the inputs and applicable rules.
