There needs to be an option for brokerage accounts, once retirement occurs (or any milestone) to change from reinvest dividends to dont reinvest dividends. And the transfer to another account isnt adequate for reasons below.
The reason that the fix of transferring accounts doesn’t work is because if you convert all brokerage accounts to transfer to retirement brokerage accounts on retirement and having those retirement accounts not reinvesting dividends is that the feature isn’t smart enough to realize that you may have more dividends than you actually need to live off of for that year! If that happens, the net end assets will actually go DOWN from not re-investing dividends!
To fix this, just change in the account page for an individual account not only the reinvest dividends check box but also a milestone for it to work off of, if needed and also a check box for only don’t re-invest dividends up until what is actually needed for expenses that year. That would make this feature bullet-proof.
