Withholding Tax & DTA for AT Investors 2026
Anyone holding foreign stocks pays tax twice — unless they pay attention. Double-taxation agreements prevent this, but only if you fill out W-8BEN and credit the WHT in E1kv field 947.
What is withholding tax?
When a US company like Apple pays a dividend, the USA withholds part up front — that's withholding tax (WHT). It never reaches your account. With proper documentation (W-8BEN form) it's 15 %; without 30 %.
The AT-USA DTA ensures you don't "lose" these 15 % — they're credited against KESt in Austria, so your total burden doesn't exceed 27.5 %.
How the credit works

W-8BEN — required for US stocks
The W-8BEN form is your declaration to the US IRS: "I am tax-resident in Austria and use the AT-USA DTA — please withhold only 15 % instead of 30 %."
Where & how to fill it out
- Trade Republic: Profile → Tax → W-8BEN (3 min)
- Scalable Capital: automatic at onboarding
- Interactive Brokers: Account Management → Tax Forms (annual reminder)
- eToro: Settings → Account → US Tax Form
- Domestic broker (George/easybank): often included in account contract
W-8BEN is valid for 3 years only. Brokers usually remind in time — if you miss the deadline, broker auto-withholds 30 %. The extra 15 % are not creditable in AT — you lose them.
FAQ — Withholding Tax
What happens without W-8BEN?
US withholds 30 %. AT credits only 15 %. You lose 15 % of your gross dividend — €150 unnecessary tax on €1,000 US dividends/year.
Do I have to enter WHT in E1kv?
Yes, definitely — otherwise you pay full 27.5 % on gross with no credit. Trade Republic tax report (PDF) lists creditable WHT separately; transfer the value to field 947.
Are Irish ETFs affected by WHT?
At fund level: yes, the ETF pays WHT on its underlying dividends (e.g. 15 % on Apple via Ireland-USA DTA). At investor level: no — when the ETF distributes to you, no WHT applies. You pay only 27.5 % AT KESt on distribution.
Do small dividends justify the effort?
From ~€30 per US stock per year, the effort pays off — Trade Republic report has it ready, you just paste the figure into FinanzOnline. Ignoring WHT loses ~5–8 % of gross dividend on average.
When is France refund worth it?
Rarely. The 12.2 % France refund is bureaucratically heavy (often needs a tax firm, 12–24 month wait). Worthwhile only for very large amounts (> €1,000 reclaimable) or long-term FR dividend aristocrat investing.
