You probably can't even use those calculators. It isn't that you have to figure out the basis as if you bought on your birthday. You have to know what the person who gave you the stock's basis was - as a gift recipient you inherited their basis.

Have you considered donating the stock? You can take a donation for the full current value and avoid this issue all together. Obviously, less money for you than if you sold it and paid tax on the whole thing, but if you were planning on giving to charity anyway, this is a good way to do it. You can even donate the stock into a donor advised fund, take the full deduction, and disburse the funds over several years or to several charites.

Yahoo Finance.
Put symbol in, left of the chart is"Historical Prices".

p.s the prices will already be adjusted for splits.

Wow,Mehta stock went up 100x?

Not Mehta - what stock?

10,000%
Not even APPL has done that well since 97, so I doubt it.

I ran into this with my wife. The record keeping was non-existent.

If you know how many shares you have today, and you have the approximate date of when the shares were purchased, there are calculators out there that'll tell you the price on the purchase date (you can simply average the open/close) for your buy price...

The reason those calculators are important is if the stock was split over time (very common in the 90s / dotcom bubble). Basically 10 shares at $10, under a 1>2 split, becomes 20 shares @ $5.


Once you know the adjusted shares/price, you just calculate the gain (or loss)... and I'm assuming it's all LTCG taxes... so apply to your bracket (0, 15, 20%? - don't quote me).

Basically, you claim $0 as your basis.

That might make sense for the initial purchase, but what about all the dividend reinvestments, which would might be at higher levels? 0 basis would mean paying taxes twice, which isn't a good strategy. I'd be surprised if the statement from the company doesn't include the average cost basis.

There are sites that will calculate that for you-- your broker might be able to do it. Or wait to you die and your heirs don't have to worry about it (unless the billionaires succeed in abolishing the estate tax in the meantime).

I couldn't prove it in a similar situation, though only 30 years, not 50. I just declared the whole thing as gains with no basis. My dad "though" he paid in the neighborhood of $1500. But had nothing to show it, plus reinvested dividends over 30 years....I just didn't have the time or patience to try to figure that out.

When we've sold stocks it gives you the option to use the average cost basis (which they calculate). If you choose to sell specific shares you will need to determine the cost basis - you should look up the rules on how to do that. We've always just chosen the average basis.
