My tax return is on my list of things to do this week. Unfortunately, I'll just put my refund back into my checking account to be used for future car payments, so nothing fun and exciting.
Haven't spent a penny of the thousands we are getting back. However, it did encourage me to get a new fridge since I know we're getting quite a bit and I can pay for this expence out of pocket. Next year we're virtually not going to pay income taxes due to expences related to selling our old home and buying the new one.
We actually put our property tax money into savings and take it out once or twice a year and cut the check(s). This is actually a greater expence for us then income taxes (at least to the feds, I think if we add in the state income tax to that the sum of the two may excede it).
