Where is a good place to store my tax return for a short term investment?

Money market account if it's that short term. Just keep it open if you lock in a good rate. We're still talking a rate of sub-1%, but that's about what you're going to get. T-bills would be longer than you want, and aren't offering the best rates right now anyway (easy money policy).

The stock market actually isn't a bad idea, but it would have to be a very safe fund. The same easy money policies that keep interest rates down are inflating the stock market.
