I use vanguard for my taxable account, but if you could, please expand on what you mean by "tax efficient investments"? I feel that my current allocation in my taxable account may not be optimal.
Typically, index funds are more "tax efficient" than actively-managed funds, since actively managed funds (on average) have more buying and selling performed than the index funds. When the fund sells a position, they have to distribute out the net gains each year - which you pay taxes on. If they didn't distribute out those gains, then your money would compound/grow for longer periods of time before taking out money for taxes, and you'd end up with a larger account balance. Also, you pay a lower tax rate for long-term capital gains versus interest and some dividends - so a MF that holds bonds and some dividend-paying stocks will cause you to pay more in taxes than the same distributions from a fund that realizes long-term capital gains.
There are some actively-managed funds which specifically aim to reduce taxable distributions by picking stocks that they plan on holding for extended periods of time and/or pay out little/no dividends and hold few/no bonds. Vanguard has several, and they all start with the title "Tax-Managed".
One other thing to remember: just as diversification is key in investing, the same holds true with taxes. It's not necessarily a bad thing to max out your tax-deferred accounts and still wind up having more funds in your taxable account than in a tax-deferred account. This guarantees that no matter what happens to tax rates in the future (as many expect tax rates to only increase), your accounts will offset each other (just like investing in index funds guarantees you'll earn market returns). If you have 90% of your investments in tax-deferred accounts and tax rates rise substantially, you might be wishing you had more in your taxable accounts.
One other item: I know you said you have health insurance through your employer...if they offer high deductible insurance plans, check out getting a Health Savings Account. All you need is a high-deductible health insurance plan (deductible greater than $1,100 for individual policy, or $2,200 for family policy).
There have been many threads on this subject: basically, you can contribute up to $2,850 or $5,650 for individual/family, respectively, to your HSA each year AND deduct it off of your taxes, REGARDLESS of your income! The funds grow tax-free, and your withdrawals are tax-free if used for health expenses. (it's the single greatest part of the tax code for individuals, and it has no income limits!)
There are a few other slight clarifications, but several posters on the forum (including me) have HSAs, and love them. If you have substantial annual health care costs, it's probably not going to be worth it, but if you and/or your wife are in fairly good health, it's an easy way to cut taxes and save additional $ in a tax-deferred/tax-free account.
