Report stock gains to the IRS by filing Form 8949 to detail each transaction (sales price, cost basis, dates) and Schedule D (Form 1040) to summarize total capital gains or losses. These are filed with your annual Form 1040, typically using data from the Form 1099-B provided by your brokerage.
Capital gains and deductible capital losses are reported on Form 1040, Schedule D, Capital Gains and Losses, and then transferred to line 13 of Form 1040, U.S. Individual Income Tax Return.
Capital Gains Tax allowances
You only have to pay Capital Gains Tax on your overall gains above your tax-free allowance (called the Annual Exempt Amount). The Capital Gains tax-free allowance is: £3,000.
The IRS has the authority to impose fines and penalties for your negligence, and they often do. If they can demonstrate that the act was intentional, fraudulent, or designed to evade payment of rightful taxes, they can seek criminal prosecution.
Who must file. Generally, any person in a trade or business who receives more than $10,000 in cash in a single transaction or in related transactions must file a Form 8300. By law, a "person" is an individual, company, corporation, partnership, association, trust or estate.
If you don't file a required 1099-K (or other 1099s), the IRS can penalize you with fines ranging from around $60 up to several thousand dollars per form, depending on how late it is, with higher penalties for intentional disregard, plus interest, as the IRS receives copies and can match it to your return. Even if you don't receive the form, you still must report the income, or you risk penalties and interest for underreported income, which the IRS will likely catch and bill you for.
The "12-month rule" for capital gains tax in the U.S. distinguishes between short-term and long-term gains: assets held for one year or less result in short-term gains, taxed at your higher ordinary income tax rates, while assets held for more than one year (over 12 months) generate long-term gains, taxed at lower, preferential rates (0%, 15%, or 20%). This rule determines if your profit gets taxed as regular income or at a reduced rate, making holding assets longer generally more tax-advantageous.
If you buy a stock and the value of it goes up, you don't have to pay taxes on those gains every year. You only pay when you “realize” the gain by selling the shares.

Yes, you can likely give your daughter $50,000 tax-free by using your annual gift exclusion and lifetime exemption, but you'll need to file Form 709 with the IRS to report the gift exceeding the annual limit ($19,000 in 2024/2025). The $50,000 gift reduces your large lifetime exemption (over $13 million in 2024/2025), meaning you won't pay tax on it unless your total lifetime gifts exceed that huge amount; your daughter never pays gift tax on the money.
