US LLC Formation From Austria: A Complete 2026 Guide

Austria's CFC regime, implemented under the EU's Anti-Tax Avoidance Directive, requires an Austrian parent COMPANY to include a controlled foreign subsidiary's passive income in its own taxable income once it holds more than 50% of the foreign entity. Like Ireland, the Czech Republic, Denmark, and Romania covered elsewhere in this series, this framework is scoped to corporate ownership — an individual Austrian tax resident who owns a US LLC personally sits outside this attribution mechanism entirely.

Vienna's startup scene has grown steadily, and Austrian founders building SaaS products, consulting practices, and e-commerce brands for international clients form US LLCs for USD invoicing, direct Stripe access, and a US-facing entity that's simpler to present abroad than an Austrian GmbH built for the same purpose. Austria's tax framework here is genuinely favorable once you understand which rules actually apply to a solo individual owner.

Worth knowing even though it doesn't change the practical outcome: Austria just raised its low-taxation threshold for CFC and related anti-abuse rules to a uniform 15%, up from the previous 12.5% (for CFC inclusion) and 10% (for interest/royalty deduction restrictions), effective for fiscal years beginning after December 31, 2025 — so this applies starting in 2026. The change was published in the Federal Law Gazette on December 29, 2025. Either way, the US federal corporate rate of 21% clears both the old and new thresholds comfortably, so this shift doesn't actually change anything for a standard US LLC — it's simply the current, correct number to know.

The US and Austria have had a comprehensive income tax treaty in force since 1996, and — less commonly — the two countries also maintain both a social security totalization agreement and a dedicated estate and gift tax treaty. That third agreement is genuinely rare among the countries covered in this series and matters if an LLC ownership stake is ever part of cross-border estate planning.

Austria uses the euro, imposes no foreign exchange controls, and moving money between a US LLC's bank account and Austria doesn't involve the outbound-approval regimes seen in several other countries in this series. Austria doesn't appear on Mercury's or Relay's prohibited-countries list, so both are workable choices for the LLC's US banking.

EasyBrise's Global Launch package ($295 first year including registered agent, $149/year renewal) handles LLC formation. The EIN application for a founder without a US Social Security Number goes through the IRS's international phone line, fax, or mail process, and EasyBrise's EIN Follow-up ($129) or EIN Priority ($99) services manage that. FinCEN's 2026 final rule permanently exempts US-formed LLCs from federal BOI reporting.

With CFC attribution out of the picture, what determines your Austrian tax bill is the flat 27.5% Kapitalertragsteuer (KESt) applied to capital income — dividends and most capital gains from securities. Unlike Denmark's two-tier aktieindkomst or Finland's two-tier capital income brackets covered elsewhere in this series, Austria applies a single flat rate regardless of the amount, which makes tax planning around distribution size unnecessary here in a way it isn't in those countries.

Austria abolished its wealth tax back in 1994 and its inheritance and gift tax in 2008, and neither has been reintroduced. That means an Austrian founder's LLC isn't subject to any annual tax on its market value simply for existing — a genuine contrast with Norway's formuesskatt covered elsewhere in this series — and there's no inheritance tax exposure on the ownership stake either.
