[...] We currently have an account with Vanguard that holds IRAs, taxable investments, and our Solo 401K from my small business. My wife and I each have Roth IRAs with USAA (we may move these to Vanguard in the future to further consolidate our accounts), I have a 401K plan through my day job, and I have a Thrift Savings Plan (TSP) account from my days in the military. My wife has 2 TSP accounts, one from her military service and one from civilian government service. I have active brokerage accounts with TradeKing and Zecco. The long term goal is to house all IRAs in one brokerage firm, and roll over any 401ks into rollover IRAs if/when my employment situation changes (my wife is currently a stay at home mom). Note about TSP accounts: One the surface it would seem like a good idea to roll these over into an IRA at Vanguard, but it is actually better for us to maintain all 3 accounts. The TSP has the lowest expense ratios I have been able to find, and my wife and I also have tax exempt contributions that were made in a war zone, meaning a portion of our withdrawals will be tax free in retirement. (The TSP functions the same as a 401K plan – contributions are made pre-tax and withdrawals are taxed. The tax exempt status of some of our contributions means some of our money will grow for 30+ years and never be taxed on the way in or on the way out.) You can read more about the pros and cons of rolling over a Thrift Savings Plan account in this article at Military Finance Network: Should You Rollover Your TSP Account Into an IRA?. [...]
