BorderFolio/Methodology/Dividend withholding

Cross-border dividend withholding

Last reviewed 24 August 2026

A dividend crossing a border is taxed in up to two steps: withheld in the fund's country before the money reaches you, then taxed again in the country where you are resident. BorderFolio estimates both steps per instrument, using the domicile of each fund you actually hold and the tax residence you configure. This page states the model, the rate resolution, the exemptions and everything the estimate deliberately does not cover.

The two-step model

For each instrument that pays a dividend:

withheld at source = gross dividend × source rate(fund domicile, your residence)
tax at home = gross dividend × residence rate − foreign tax credit (where the residence grants one)
kept = gross dividend − withheld at source − tax at home

The two steps are computed separately and shown separately. A resident of a country with no personal income tax has a real first step and a zero second step; a resident of a treaty country with a credit may see a large first step that mostly offsets the second. Collapsing them into one "effective rate" hides which of the two you can actually do something about — so BorderFolio doesn't.

How the source rate is resolved

The rate is never taken from a portfolio-wide setting and is never user-editable: it is derived per instrument from the fund's domicile and the treaty status between that country and your tax residence.

InstrumentRate appliedWhy
US-domiciled ETF or US stock, residence with no US treaty in force30%US statutory rate on dividends paid to a non-resident.
US-domiciled ETF, residence with a US treatyTreaty rate, commonly 15%Applies only where the broker holds the required documentation, typically a W-8BEN.
US-domiciled ETF, treaty suspended30%A suspended treaty gives no relief; the statutory rate returns.
Irish-domiciled UCITS ETF15% at fund levelThe fund receives US dividends under the US–Ireland treaty; Ireland applies no further withholding to non-resident investors.
US Treasury or money-market distributions0%Interest-type distributions are exempt — deriving the rate from domicile alone would wrongly charge 30%.

The exemption row matters more than it looks. A portfolio holding a Treasury ETF alongside a world equity ETF has two US-domiciled funds with completely different outcomes, and any tool that reasons from domicile alone gets one of them wrong.

A worked example

Resident of the UAE, holding a US-domiciled world equity ETF paying $1,918 in gross dividends over a year:

The same gross dividend from an Irish-domiciled UCITS tracking a comparable index would lose 15% at fund level — roughly $288 — instead of $575. Both figures are computed on your position sizes, not on a generic example, and neither is a recommendation to switch: switching has costs and tax consequences of its own, and the comparison exists so you can weigh them.

US estate-tax exposure

Separately from dividends, US-situs assets — US-domiciled ETFs and US stocks — above a $60,000 threshold can expose a non-resident, non-citizen's estate to US estate tax at rates reaching 40%, unless an estate tax treaty provides relief. BorderFolio flags the threshold against your current US-situs value and projects when your actual contribution pace crosses it. Where that pace differs materially from your stated plan, both are shown; the projection is never quietly based on the more flattering one.

Projections and comparisons

Long-horizon comparisons — for example an accumulating UCITS structure against the distributing structure you hold today — use the expected return of your current allocation for price growth, and each fund's own trailing yield for dividends, with withholding applied per instrument. No fixed "market returns 7%" constant is used, and dividends are never grown at an equity growth rate.

Displayed amounts are rounded for readability, and the components of a total are rounded so that they sum to the total shown rather than disagreeing with it by a dollar.
