Whether you mapped out an investment strategy for months or certain stock news quickly piqued your interest in the market, you might not have given much thought to your taxes. Read on to learn how investment returns can impact yourtax return.
Taxes on stocks
Investing in and trading stocks can be a great tool for building wealth. But like the income from your 9 to 5, the money you make is taxable.
Know your tax terminology
Before we dive into tax rate specifics, let’s cover some basic, need-to-know terms.
Cost basis: Amount you originally paid for a security plus commissions, which serves as a baseline for determining gains or losses.
Capital gains: Profit generated by selling a security for more money than you paid for it (or buying a security for less money than received when selling it short).
Capital losses: Loss that occurs when you sell a security for less than you paid for it (or buy a security for more money than received when selling it short).
Dividend: Portion of a company’s earnings paid to eligible stock owners on a per share basis.
When you own dividend-paying stocks, you might receive a payment a few times a year. That money is usually taxable, though the rate varies depending whether it’s a qualified or nonqualified (a.k.a. ordinary) dividend.
The tax rate on qualified dividends is 0%, 15% or 20%, depending on your tax bracket. The higher your ordinary income tax, the more taxes you’ll pay. Ordinary dividends are taxed at your normal income tax rate.
If you reinvest dividends through a dividend reinvestment plan (DRIP), you have to pay taxes as though you received the cash. If your DRIP allows you to purchase additional shares at a discounted price, you’ll be taxed the difference between the reinvested cash and the fair market value of the stock.
If you receive dividends in the form of additional stock, they’re typically not taxable until you sell the shares.
Capital gains tax rates
Profit made on a stock you owned for a year or less before selling is taxed at the short-term capital gains rate, which is the same as your usual tax bracket.
Returns made on a stock you owned for longer than a year are subject to the long-term capital gains tax rate: 0%, 15% or 20%, depending on your ordinary income.
Tax rates shown here are for illustrative purposes only. Actual tax rates may vary based on your personal circumstances.
Stock trading tax considerations
Certain trading strategies may lower your tax liability:
Tax-loss harvesting involves selling securities at a loss to lower your capital gains tax liability. The IRS allows you to deduct up to $3,000 in realized losses (or $1,500 if you’re married filing separately) to offset capital gains tax or taxes owed on ordinary income.
Pro Tip: Beware of wash sales. Wash sales occur when you trade or sell a stock for a loss and buy the same security or a “substantially identical” security within 30 days before or after the trade. If you re-buy the security within 30 days, the IRS’s wash-sale rule prevents you from deducting it as a capital loss.
Holding stocks long-term
In general, if you hold a stock for longer than a year, you’ll pay a lower tax rate when you sell: the long-term capital gains rate.
Invest in a tax-optimized portfolio
Certain investment accounts, like our tax-optimized Robo Portfolio, can help you maximize your after-tax contributions through tax-advantaged Exchange Traded Funds, or ETFs.

Maxit adjusts routinely for options exercise and assignment as well as diverse corporate actions. The service even fills out your Schedule D and D1 automatically at year’s end.
Tax ramifications of trading as a business
Compared to individuals, trading businesses can usually write off greater losses, claim broader business-related expenses related and worry less about wash sale rules.
If you meet the following broad criteria, talk with a tax professional about if you should consider establishing your trading as a business:
You seek to profit from daily market movements of securities, not just dividends or capital appreciation
Your trading is substantial (338+ trades annually)
Your trading activity is conducted with continuity and regularity
Declaring yourself a professional trader isn’t as clear-cut as other forms of self-employment. A tax professional can inform you of the rules that apply to your personal situation.
Handle trading taxes like a pro
Filing taxes can be confusing, especially if you have multiple income streams to account for. So, don’t be afraid to consult a tax professional who can ensure you make decisions that are best for you and your trading activity.
