1. As a Non-Resident Alien  and not living in the USA, you are still taxed on your  US Passive income -- at a flat 30% rate.

2. You file your return on Form 1040-NR ( not supported by TurboTax ---you can use a tax professional  back in your home country , UK or here in the USA or use service like  SprinTax, an affiliate of TurboTax )

3. You should keep your  US bank account valid , especially if you are expecting a refund from the IRS .

4. Note that since US tax calendar is based on Calendar year, if you leave the country permanently during the middle of the year , you  may be treated as a dual status alien --- 01/01/XX till the departure date as a Resident & taxed on world  and thereafter till 12/31/XX as a Non-Resident alien, taxed on ONLY US sourced income.

@Helen123 ,  thought you were going to stay here for some time ( based on your earlier questions ).

Does this answer your query ?   Is there more I can do for you ?
