I have a very silly question. I want to pour my allotted $5500 for 2015 into a tIRA. I wanted to put it into VTSAX, but just saw that the minimum investment is $10K. There is no way around this, correct? I already have a Roth IRA with Vanguard with ~$5600 in VTSMX. In most years, my income doesn't allow me to take advantage of the tax break from the tIRA. However, taking 5 months of maternity leave in 2015 (largely unpaid) actually qualifies me a break for the tIRA. Do you see any issues with taking advantage of this for this year only?
