What is the cost basis for a stock that is a result of a stock split 10 years ago ??? Help as soon as you can ! Been trying to figure it out but NOT sure I'm correct.

Your broker should be able to help you with this.

The total basis is still the same. You just have a different number of shares.

If your basis was 30 dollars per share before and it split 2-for-1, then your new per-share basis is 15 dollars.

If you have the same brokerage, the cost basis should be adjusted after the stock split.

If you can provide more information, I can check into it.

assuming the split resulted in more shares of the same stock, your tax basis per share is what you originally paid divided by the total number of shares. so if you paid $500 for 100 shares and got an addition 100 shares the cost/share is $500/200

@pakikiheiya

if you bought before the split,

divide your old cost per share by the <split factor>.
