ShutterStock: US Sources vs Non-US Sources

I just discovered today that ShutterStock had added a new 'feature' called 'payout history'. In the payout history, it lists down all your past records of payout, the date and amount.

What is interesting is it also distinguishes the sources of downloads. It shows you how many of your images are downloaded by people or entities from the US, and how many are from non-US sources. The reason is for revenues from US sources, you are subject to 30% tax withholding.

In my case, I don't know whether I shall say it is lucky or unlucky that only ~10% of my revenues are actually from the US, while the remaining 90% are from non-US sources. As a result, the 30% tax withholding rule has a much smaller impact on me than previously thought. What a relief!
