Sorry not sure if you got my last message...
Here is some additional information below... although it may be irrelevant because it's referring to RSU shares granted to a UK employee within the UK:
You are subject to income tax and national insurance contributions (“NICs”) when your RSUs vest and the underlying shares are issued to you. The taxable amount is the fair market value of the shares issued to you at vesting.
Your employer is required to calculate income tax and NICs and pay these amounts to HM Revenue & Customs (“HMRC”) when your RSUs vest. Your employer will withhold any applicable income tax and NICs under the Pay As You Earn system or by any other means set forth in your award agreement.
Your employer is also required to report the details of the grant and vesting of the RSUs, the acquisition of the shares and the tax withheld to HMRC.
You are responsible for including any income realized from RSUs in your annual tax return, and for paying any difference between the amount withheld and your actual tax liability.
If a dividend is declared on common stock after you acquire shares under the Plans, you are subject to tax in the United Kingdom on any dividends you receive. In addition, you are subject to US federal income tax withheld at source. You may be able to claim a reduced rate of US federal income tax withholding on such dividends as a resident of a country with which the United States has an income tax treaty. You must have a properly completed US Internal Revenue Service Form W-8BEN on file in order to claim the treaty benefit. You also may be entitled to a tax credit in the United Kingdom for the US federal income tax withheld.
You are responsible for reporting and paying taxes on any dividends paid on shares you hold. To determine your tax obligations for dividends, consult a professional tax advisor.
If a dividend is declared on common stock and you hold unvested RSUs on the record date, you are eligible for dividend equivalents. You are subject to income tax and NICs on any dividend equivalents paid to you when the RSUs vest. Any accumulated dividend equivalents are used to help offset taxes you owe on the RSUs. This enables the company to release more vested shares to you than it otherwise would.
Your employer will withhold any applicable income tax and NICs under the Pay As You Earn system when the RSUs vest and the dividend equivalents are paid to you. You are responsible for paying any difference between your actual tax liability and the amount withheld from the dividend equivalent payments.
Selling company shares
You are responsible for reporting and paying any capital gains tax resulting from the sale of shares acquired from RSUs.
You are subject to capital gains tax on any gain you realize when you sell your shares if the gain exceeds your annual personal exemption amount (currently £11,000). The taxable amount is the difference between the fair market value of the shares at vesting and the sales proceeds.
If you acquire other shares, you will need to take into account the share identification rules in calculating your capital gains tax liability."
