That's why I'm paying a cpa lol.
My 0-research understanding is that if you were to buy a share of a stock for $80,
then it grows to $100
and a dividend is issued for $25
but actually $15 is a basis return and $10 is taxable dividend income
(and the share price drops to $75 due to payout)
and then it grows back to $100 and you sell.
You owe taxes in the dividend year on the $10 taxable income
Your basis was $80 but you had $15 returned, so your basis is now $65
So when you sell your gains would be taxed on $100-65=$35
even though your gain was only $20 if considered from your original basis amount.
So a return of basis helps you not pay tax at dividend time, but actually increases your tax burden at final sale time. But still, you're better off with a real cost basis, even if reduced by the adjustment amount, than a cost basis of $0 (where in the example you would owe taxes on all $100).
