Hi,
Hoping someone can clarify a few things for me regarding the taxation of my 401k distribution when I finally take it (after age 59.5). Let's say I'll have $1,000,000 in the 401k by then - probably well short but it's a good round figure for illustration. As I've mentioned before on this forum I'm a UK citizen and UK resident, and probably will be when I retire. I have a 401k from the years I worked in the US. Let's assume the current rules and tax rates will be the same when I retire (I know, I know).
I understand that if I take a lump sum distribution, 30% will be automatically withheld and, given the amount involved, I'd owe some more to the IRS because it would put me in the highest tax bracket. My conclusion is that I'd be barking mad to do this. Correct? So...
If I understand my plan's rules correctly, I can take periodic payments. Let's say I were to take 10 annual distributions of $100,000 (or until it ran out). I'd still have 30% of each withheld in the US (I think) but since I'd be in a lower tax bracket I'd get some tax back if I filed. If my rough calculations are correct I figure I'd pay about half the tax overall compared with taking it all in one go.
Does this sound correct?
The other thing I'm not sure about is whether the UK would want to tax those annual distribtions as well, or does the double taxation treaty prevent this. Or, would the UK want to tax them at say 40% but give relief under the DTA for the 25% (say) paid to the US.
Would appreciate any thoughts and comments (especially if I've got it completely wrong), and/or advice. Thanks.
