<prompt> Human: Hi Reddit,I was wondering if there are tax-advantaged alternatives to IRAs and 401Ks. My wife and I save over half of our money. We max out our IRA contributions every year and I put in just enough money to get my employers full match on my 401k. The rest of our money besides an emergency fund goes into a few Vanguard funds VTSAX and VBTLX.We would like to start putting more money into my 401k - but my company uses Fidelity - and for whatever reason they are only offering a limited number of funds... none of which really appeal to me. Is there an alternative I should look into so we can save more money through tax-advantaged accounts? If not, is it better to continue investing in solid, low-cost funds that I pay taxes on - or better to invest in a fund I dont have as much confidence in but reap the tax benefits? Thank you!  <response>: Look very closely at your Fidelity choices, you should be able to find something similar to VTSAX. For example, I have an SP 500 fund called Equity Index Fund and under the fund Objective it says The Fund seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of a particular index its Underlying Index. The Underlying Index is the SP 500 Index.
