Slight thread drift here. Sorry.
Anyone domiciled in Anchorage notice something similar. Every year for the first few months they withhold Alaska unemployment tax. It seems when they hit some magic number (about $200) they stop. It's happened consistently for the past 3 years. Not a big deal but along the same line; I don't live there and only "work" there for 1 hour at the beginning of a trip and 1/2 hour at the completion of a trip...a total of 1.5 hours per month.
