What is the W-8BEN form?

Find out what W-8BEN is and why you need to know about it if you want to trade US shares.

To trade US stocks you need to complete a W-8BEN form so that you’re entitled to tax savings on interest earned. Often, brokers that allow you to trade US stocks with them will allow you to fill out and return your W-8BEN form to them. Here’s the basic information on what the form is for and how you fill one out with your broker.

What is a W-8BEN form for?

The W-BEN form is only required when trading US shares. In short, it helps determine your tax status. If you’re not a US citizen, then as a foreign investor, you’re subject to US tax of 30% of the income you receive from dividends, premiums, rents, royalties, annuities or other fixed annual gains.

Who needs to fill out the W-8BEN form?

You’ll need to fill out the form if:

  • You are not a US citizen; and
  • You plan to buy US shares

How often do I need to fill out a W-8BEN form?

You’ll need to fill out a W-8BEN form with every broker you use every three years – if your broker helps you manage your W-8BEN form then it’ll let you know when it’s time to renew. If it’s done digitally, you’ll be prompted to do so within the app or on the website.

What does the W-8BEN form do?

By submitting a W-BEN form, your broker is able to claim a US tax reduction on your interest and dividends from US shares, either to 15% or to 0% if the shares are held in a self invested personal pension (SIPP).

This means that you’ll be subject to less tax, so more of your profits end up in your pocket.

Will my broker sort the W-8BEN form for me?

Some brokers will assist in completion of your W-8BEN form, while others expect you to fill it out and send it to them. We’ve taken a look at some of the brokers that offer US stocks below:
