Given the following...
• Early retired, withdrawing from taxable brokerage
• Invested in VFIAX (Vanguard S&P500 mutual fund)
• 0% federal LTCG bracket, 3% state
• Have older shares for which Vanguard does not know cost basis
• Want to keep everything as simple as possible
...Is there any reason I should be concerned that I went with Average Cost when I did my first ever stock sale?
I'm *thinking* it should be fine, since I can't see the advantage in micromanaging lots for tax efficiency when my cap gains taxes are going to be almost zero (for now and the foreseeable future, I'm a very low spender).
Searching around I read a lot of comments that weren't in favor of Average Cost, but it seemed like the context was higher-spending individuals concerned about tax efficiency.
But I still thought I'd ask for a sanity check on whether I'm missing some major problems. Thanks.
