US Withholding Tax - 871(m)

Due to new tax regulations under U.S. code section 871(m), there have been changes to the way U.S. equity dividend adjustments paid to clients on CFDs on shares in U.S. incorporated companies, certain ETFs and indices, are taxed.

For the majority of City Index customers, you are not required to take any further action. However, please ensure you read the information below and take any necessary actions to ensure that the appropriate tax treatment is applied to your account.

Who will be affected?

This regulation applies to City Index individual and joint accounts, corporate accounts, trusts and partnerships with long CFD positions on shares in US incorporated companies, ETFs which track U.S. equities and any non-qualified indices which contain U.S. equities that were, in each case, opened on or after 1st January 2017.

The withholding tax does not apply to:

  • Qualified indices: examples of qualified indices may include: Dow Jones Industrial Average (Wall St), S&P 500 (SP 500)
  • Short positions
  • Trades opened before 1st Jan 2017

What will the impact be?

City Index clients trading in affected products will generally be subject to a 30% withholding tax on dividend adjustment payments that must be remitted to the U.S. Internal Revenue Service, although some countries have tax treaties that could result in a lower rate being applied. For example, a UK tax resident would be subject to 15% tax withholding rather than 30%.

Withholding tax will be applied to any dividend adjustment that is due to be paid into your account on any affected products, meaning you will receive the net amount of the dividend adjustment after tax.

What do you need to do?

Individual and joint accounts

For individual and joint accounts, City Index will use the information we hold on file obtained from you during our on-boarding process and any subsequent updates that we have received from you to determine the rate of tax that will be applied. It is important that the information we hold about you, particularly your address, is correct to ensure that the correct amount of withholding tax is applied.

If you think that City Index may not have your current address, it is important that you contact our Client Management team as soon as possible at

If you only pay tax in the country in which you live (and we have your correct Country of Residence on record), you need take no further action. City Index will ensure the applicable rate of withholding tax, based on the residence information you provided to us, will be applied automatically to any dividend adjustments that you may receive.

If you also pay tax outside the country in which you live, and believe that you are a tax resident of that second country, and wish to benefit from a reduced tax rate under the treaty between such country and the United States, you will need to take further action as follows:

U.S. tax residents

If you pay individual federal income tax in the United States, please provide a copy of one of the following documents:

  • U.S. passport (in date)
  • Birth certificate (issued by a US hospital)
  • U.S. naturalization certificate
  • U.S. green card

In addition to the above, please provide a completed and signed U.S. tax form W-9 (including a valid SSN).

You can upload this information securely to City Index using the document uploader in MyAccount. Alternatively contact our Client Management team on

Non-US tax residents

If you believe that you are a "tax resident" (i.e. pay income tax) of a country outside of your country of residence (excluding the United States) which has a tax treaty in place with the U.S. with a lower taxation rate than your country of residency, then please complete and return the form W-8BEN.

This will allow you to claim treaty benefits for that country.

Corporate accounts (including trusts and partnerships)

For non-U.S. Corporate accounts (including trusts and partnerships), withholding tax will be applied at the default rate of 30% until the following form is completed: Tax Treaty for Legal Entity Accounts. Based on the information supplied, we will apply the applicable rate of withholding tax, which may be different from the 30% default rate.

For U.S. Corporate accounts (including trusts and partnerships), please provide a completed W9, with a valid TIN/SSN.

Information reporting

Where dividend adjustments on affected products have been paid to you and taxes withheld, we are required to send relevant information to the IRS on an annual basis, which we will do directly or via a third-party agent engaged for that purpose. This information includes a summary of the withholding tax paid to the IRS during the calendar year, the gross dividend adjustment payments applicable to affected products that you traded and the net dividend adjustment paid to you.

Please note that your account statements and information available through the City Index platform will only show the net dividends paid to you.
