Tax withholding determination:

Generally, tax is withheld at a rate of 30% on payments of US source stock dividends and substitute payments in lieu. The rate of withholding may be reduced if there is a tax treaty between your country of tax residence and the US

US Tax withholding on distributions from Publicly Traded Partnerships is withheld at 37% (2018) as this is earned income in the US

Updating Form W-8:

Forms W-8 are valid for the year in which they are signed and for the next three calendar years. For example, a Form W-8BEN signed on March 5, 2018, remains valid through December 31, 2021, and must be resubmitted to IBKR no later than January 30, 2022.  Failure to update your W-8 form will result in withholding on all income including gross proceeds from securities sales.

Requirement to Complete Form W-8:

Form W-8, Certificate of Foreign Status, must be on file with IBKR. This form must be renewed every three years.

Treaty rates, if applicable, will no longer apply.

Note that if you complete Form W-8 you will not receive a Consolidated Form 1099, but you may receive Form 1042S.

Withholding Penalty

If you fail to provide a Form W-8, or do not resubmit a new W-8 when prompted upon the three-year expiration, additional withholding will apply. IBKR encourages its clients to consult with their tax advisors for further guidance on how to seek relief for any tax withheld.
