You only report stock on your tax return when you sell it. You do not report it when you inherit it.
When you sell the stock you will have to report the basis. Your basis for inherited stock is the market value on the date of death of the person you inherited it from. So if you have not sold any of the stock yet, you should determine your basis now and keep a record of it so you will have the information when you sell it. If you are holding the stock in a brokerage account, the brokerage might let you put the basis into their records for your account.
A sale of inherited stock is always considered long-term, no matter how long you or the person you inherited it from actually owned it.
Your age and being a student don't make any difference. However, if you do sell any of the stock you might be subject to "kiddie tax." Kiddie tax means that investment income over a certain amount ($2,700 for 2025) is taxed at your parents' tax rate. Kiddie tax applies if you are not filing a joint return and any one of the following is true.
(1) You were under 18 at the end of the year.
(2) You were 18 at the end of the year and your earned income (from working) is not more than half of your total support for the year.
(3) You were under 24 at the end of the year, you were a full-time student, and your earned income (from working) is not more than half of your total support for the year.
