I love lending the Government money each year. I'm not competent enough to use that money to build up my savings and use the miracle of compound interest.

Umm last 4 year's it's been around $4500 and my witholdings and income are within $500 of last year on the income side and $40 on the tax witholding side.

"Based on the information you previously entered, your anticipated income tax for 2007 is $86, and your projected withholding is $1,652. Your anticipated overpayment is $1,566. Since it's December, any changes to your withholding that you request on Form W-4 may not go into effect until next year." What does this mean?

re: FORGOTTENPASSWORD, I know my refund isn't free money, but it is forced savings that always comes in handy for paying off my swollen post holiday / winter vacation credit card bills.

My refund typically comes out to about $40 every year. And I know people HATE to hear this, but you want to make it to where you either get a tiny refund or end up paying a small amount to the IRS. A refund may seem like "free money" when in fact it is the government/state paying back money you loaned/overpaid to them & money that you could have been earning interest on in a high yield online savings account or cd, etc. etc..

Now let the flaming commence from the "Refund = "free money!" crowd

It doesn't handle people with all sorts of special exceptions, but it looks pretty solid.

I found this calculator particularly helpful the year I got married. It let me calculate (generally) how much additional money my wife and I had to withhold to make up for the fact that we got married that year (it could have resulted in a devastating tax bill if we hadn't planned ahead).
