I just completed the W-BEN form using my old NCM HIN, and it worked. You need to answer some questions and then the relevant form is generated, which you need to print, sign, scan and email to an address in the US that Computershare will advise on screen.

Page 147 of the Scheme booklet sets out the tax treatment of dividends from Newmont,


So with my limited tax knowledge, I understand this means you include the dividends on your Australian tax return and given there is a tax-treaty in place between Australia and the US, you also note the tax credit (i.e. the 15% tax already deducted). The purpose of the tax treaty is to ensure you're not double taxed.

NCM paid fully franked dividends where you got the 30% tax credit (i.e. fully franked), but for NEM it now means you only get the 15% US withholding tax credit and will have to pay the balance of your marginal tax rate to the ATO on the dividend amount (so basically the same as a 50% franked dividend rather than 100% franked).

Don't take this as official tax advice but hope this helps.
