How much US withholding tax does a Slovak resident pay on US dividends?

15% on portfolio dividends from US-domiciled funds and US stocks under the US–Slovak income tax treaty, according to the IRS treaty table, provided a valid W-8BEN is on file with the broker. Without it the statutory 30% applies. Slovak tax on the foreign dividend is a separate second step that depends on your own position.

Why do purchase dates matter so much for a Slovak investor?

Because Slovakia's exemption for gains on securities traded on a regulated market runs on how long each lot was held — the well-known one-year test. A position built by monthly buying is dozens of lots, each with its own clock. A tracker that stores every purchase with its own date preserves exactly the record that question is answered from. Confirm the exemption's current conditions with an adviser.

Does BorderFolio connect to Slovak brokers or platforms like XTB or Finax?

No connection of any kind — you upload the statement the platform already produces, as PDF, CSV, plain text or a screenshot, and the holdings and transactions are extracted for review before anything is saved. That also means it works with platforms that offer no API at all, and no credentials are involved at any point.

Is an Irish UCITS better than a US ETF for a Slovak investor?

Not on withholding — both routes lose the same 15% to the US, at the account or inside the fund. The structural arguments are what remain: an accumulating UCITS produces no annual distribution to declare, UCITS are what EU brokers can offer retail investors under PRIIPs rules anyway, and Irish funds are not US-situs assets for US estate tax, where Slovakia has no treaty protection.

A portfolio tracker for Slovak investors

Last reviewed 4 September 2026

Investing from Slovakia looks deceptively simple — the currency is the euro, the broker is probably XTB, Interactive Brokers or Trading 212, the fund is probably an accumulating UCITS. The complexity hides in two places: a one-year holding test that runs per purchase rather than per position, and dividends that cross a border before they reach you. This page is about tracking both properly.

The euro helps, but doesn't finish the job

Having the euro removes one whole class of confusion — your contributions and your tax return live in the same currency. What it does not remove is the currency inside the portfolio: a world or S&P 500 fund is overwhelmingly dollar assets, and in a year when EUR/USD moves several percent, that move lands in your euro-measured return looking exactly like market performance.

BorderFolio keeps the layers apart by construction: every transaction is converted at the rate on the day it happened, never at today's rate, so a €300 monthly contribution stays €300 in the record forever, and what the dollar has done since shows up as market movement — visible, not laundered into "what I saved". The method, and its limits.

The one-year test runs on dates you probably didn't keep

Slovak tax law exempts gains on securities traded on a regulated market once a holding period has passed — the widely used one-year test. Its conditions should be confirmed before you rely on them, and this page deliberately states no rates. What matters for tracking is the mechanics: the clock runs per purchase, not per position.

A UCITS position built by monthly buying over three years is thirty-six lots, each with its own date, some past the year and some not — and the broker's current-holdings screen shows none of that. A tracker that stores every purchase with its own date preserves exactly the record the exemption question is answered from, whether you answer it yourself or hand it to an adviser.

Withholding, and the paperwork it depends on

Slovakia has an income tax treaty with the United States, so a Slovak resident holding US-domiciled funds or US stocks is subject to 15% US withholding on portfolio dividends rather than the statutory 30% — provided a valid W-8BEN is on file with the broker. The form expires; when it does, the 30% applies regardless of what the treaty says, and the difference appears quietly on the dividend line of a statement nobody reads closely.

That is only step one. Step two is Slovak tax on the foreign dividend — and not a number this page will state, because it depends on your full position. What the product does is model both steps from the residence and rates you configure, per instrument, against dividends your portfolio actually paid. The Slovakia withholding page covers step one in full.

The UCITS default, and what it does and doesn't buy you

Most Slovak index investors are in Irish-domiciled accumulating UCITS, partly by choice and partly because that is what an EU broker can offer a retail investor at all. On withholding the choice is a wash: a Slovak resident loses 15% at source on a US-domiciled fund, and an Irish UCITS suffers the same 15% inside the fund on its US holdings. Same number, different place — and the statement never shows the second version.

The real arguments are structural. An accumulating share class produces no distribution to declare each year. And Irish funds are not US-situs assets for US estate tax, which matters because there is no US–Slovak estate tax treaty: US-situs holdings above $60,000 can expose an estate to US estate tax on the excess — a threshold an ordinary index investor crosses in an ordinary month, with no warning on any dashboard. What domicile changes.

Whatever your broker is

Upload the statement it already produces — an XTB or Trading 212 export, an Interactive Brokers activity statement, a Finax overview, a CSV, or a screenshot of a mobile app. Positions, purchases, dividends and stated commissions are extracted and shown for review before anything is added. There is no broker connection and no credentials involved at any point, which also means no dependency on whether your platform offers an API. How import works.

A multi-month export is worth more than a current-holdings screenshot: it rebuilds the contribution history behind the position — which for a Slovak investor is also the lot-by-lot date record the one-year test runs on. Accounts at different brokers can sit in one portfolio, or in separate portfolios with a combined view on Pro.

Limits, plainly

Not tax advice, and not a filing figure. Every number is an informational estimate on your own holdings, with its assumptions shown. See the disclaimer.
Step one comes from the IRS treaty table, not from your account; what your broker actually withheld is on your statement and can differ.
Step two is modelled from the rates you configure, not from Slovak legislation encoded in the product.
The one-year test is not computed for you. The product preserves the per-lot dates the test runs on; whether a given sale qualifies is a question for you and your adviser.
Rules change — the exemption's conditions may move, which is why nothing above states them as permanent.
Individual bonds and treasuries are not imported yet; funds holding them are.
