Frequently Asked Questions
Q. Which is more tax-efficient?
Technically, ETFs (VTI) are slightly more tax-efficient due to how they handle capital gains. However, Vanguard has a unique patent that makes VTSAX just as tax-efficient as VTI. It’s a tie.
Q. Can I convert VTSAX to VTI?
Yes. If you hold VTSAX at Vanguard, you can usually convert it to VTI tax-free. However, converting VTI back to VTSAX is not as simple and would require selling (a taxable event).
Q. Should I own both?
No. They are redundant. Choose one based on your preferred trading style and stick with it to avoid wash-sale rule complications.
