Hello, this is a very helpful thread.
Am I correct in understanding that an early withdrawal of a US pension plan that is not a liquidation of the pension is not a lump sum payment? Because this is not considered a lump-sum payment, it would be subject to US and UK taxation? For example, one takes an early withdrawal of $25K of a $100K US pension plan leaving $75K remaining in the US pension plan with the intent to receive future payments at retirement age. The $25K would be subject to both US and UK tax?
I appreciate your help.
