Investing in stocks can be lucrative, but it also comes with tax implications. As a beginner, it's important to understand how stock gains and losses impact your taxes so you can maximize returns. This guide covers key questions on taxes for novice stock investors.
Do I Owe Taxes on Stocks I Haven't Sold?
A common beginner question is whether you owe taxes on investment gains if you don't actually sell the stock. The short answer is no. Let's break this down.
When you buy a stock and its value increases, that is an unrealized gain. You have not "realized" or locked in the gain until you sell the stock. Unrealized gains do not trigger tax liability.
Taxes only apply when you realize the gain by selling the stock for a profit. This is known as a realized capital gain and is a taxable event. The bottom line: Don't worry about taxes until you sell.
Do I Owe Taxes if I Leave Gains in My Brokerage Account?
Another scenario beginners may encounter is selling a stock for a profit but leaving the money in their brokerage account. Do you still owe taxes in this case?
Yes, you do. Here's why:
- Tax liability is triggered when you close your position by selling the stock.
- What you do with the proceeds afterwards does not impact your tax obligation.
- As soon as you realize a capital gain by selling, it becomes taxable income for that year.
- It does not matter whether you transfer the money back to your bank or leave it with your brokerage.
The timing of the sale is what creates the tax liability, not the transfer of money.
What Tax Rate Applies to My Gains?
This depends largely on one factor - your holding period, or how long you owned the stock before selling.
- If you sell a stock within one year of buying it, your gains are taxed at your ordinary income tax rate. These are called short-term capital gains.
- If you hold the stock for more than one year before selling, your gains are taxed at the lower long-term capital gains rates.
Long-term rates can be 0%, 15% or 20% depending on your tax bracket. The maximum short-term rate is 37%.
Clearly, long-term gains are more tax advantageous. Hold your positions over a year when feasible to minimize taxes.
Can Losses Offset Gains?
If you sell a stock at a loss, it's not all bad news from a tax standpoint. Realized losses can offset realized gains.
- A loss realization creates a deductible capital loss on your tax return.
- Deductions reduce your taxable income, lowering your tax liability.
- Capital losses first offset capital gains. Leftover losses offset up to $3,000 of ordinary income.
- Excess losses can be carried forward to future tax years.
The key takeaway is don't ignore losses. Track them closely as they can provide significant tax savings.
How Do I Report Gains and Losses on My Taxes?
Come tax time, your brokerage will issue Form 1099-B. This comprehensive form reports:
- Date/proceeds of each sale
- Cost basis and holding period
- Short-term and long-term classifications
- Total capital gains/losses
With 1099-B in hand, simply transfer the data into your tax prep software, or provide it to your accountant. The form makes reporting seamless.
