Looks like I managed to do it again. I overpaid federal taxes by $6,000 and state taxes by $2,000. I'm already claiming five exemptions on my W-4, though. *shrug* I suppose it's better being owed than owing.
$8,000 in returns will be very, very handy this year. Google just paid me a bonus for performance last year, equivalent to about 27% of my salary (16% after taxes), which is a solid down-payment on the kids' college educations _and_ Heather's.
