So I pay a lot in taxes (33% bracket) including the alt minimum tax, but I still always get a refund. I max out 401K, make charity donations, pay a healthy five-figure state tax, mortgage interest, etc. Last year I got a 2K federal refund. This year was only $500 because of those pesky capital distros from the Vanguard mutual funds. Anyway, when I filed, TurboTax spit out estimated tax payment forms for this year. Why would I need to do that when I'm still getting a refund? I know a lot of people in my sitch make estimated tax payments, but I take zero deductions and get a very healthy amount taken out of each paycheck. I'm going to ignore this for now.
