Last week I saw a thread somewhere on these forums (I wish I could find it again) about how index funds will sell mid-year and pass the tax burden of those sales onto the owners of the index funds.
For a taxable account, I've read that using an ETF solves this problem, however, I don't really understand what the difference is.
My wife and I currently have only about $15k in our taxable account, and I want to know if it's worthwhile to move it from VTSAX to VTI. Also, will that somehow alleviate any taxes we might owe for 2017 (my gut would say no, if those sales have already taken place). What limitations does buying an ETF impose over an index fund?
