I have been moving funds between my IRA and into my Roth IRA for the last number of years, almost all funds are now in Roth IRA - and all tax paid on those transfers. It has been just over 5 years since i started doing this. I now want to withdraw some of my Roth IRA balance, which i assume to be now tax free ( or tax paid to be more precise) - however when doing this on Vanguard it does not allow me to select a 0% tax withholding? Only a min of 10%. I am confused. The money is going into my US Citibank account. I live in the UK. Do i have to still pay the 10% and then claim it back on my annual tax return? I assumed it would be withdrawn with no tax liability. Help!
