How much tax do you have to pay on stocks

Investors often ask: how much tax do you have to pay on stocks? This practical guide answers that question for U.S. taxpayers and covers the taxable events (sales and dividends), holding‑period rules, federal tax rates (short‑term vs long‑term), additional levies like the Net Investment Income Tax, state and local considerations, recordkeeping, reporting, and common planning strategies. Read on to learn clear examples and steps to manage and estimate tax liabilities — and how to incorporate tax‑aware strategies into your investing routine with Bitget products where helpful.

Overview

Taxes on stocks depend on whether gains are realized (you sold shares for more than you paid), how long you held them, the type of income (dividends vs capital gains), your filing status and taxable income, and whether special rules (wash sale, inherited basis adjustments) apply. Unrealized gains — paper profits while you still hold shares — are not taxed in taxable accounts until you sell. Cost basis and holding period determine whether a realized gain is short‑term or long‑term and therefore which federal rate applies. In addition to federal taxes, many states and localities tax dividends and capital gains at ordinary income rates or by special rules.

Note on timeliness: as of May 2025, financial reporting highlighted elevated market valuations and large portfolio activity by major investors; these market conditions can influence decisions about selling winners and triggering taxable events. As of December 2025, consumer finance reporting emphasized the value of claiming workplace 401(k) matches and considering Roth options to shelter investment growth from current or future taxes. (Reporting examples: The Motley Fool and consumer finance outlets, May–December 2025.)

Key concepts

Capital asset: Stocks you own in a taxable account are generally treated as capital assets for tax purposes. Gains or losses when you sell are capital gains or losses.
Cost basis: The amount you paid for shares (including commissions and fees) — your starting point for computing gain or loss. Adjusted basis may reflect reinvested dividends, return of capital, or other adjustments.
Realized vs. unrealized gain: Realized gains occur when you sell shares; unrealized are paper gains while holding. Only realized gains are taxed currently in taxable accounts.
Holding period: The length of time you held a security before sale. A holding period of more than one year qualifies a gain as long‑term; one year or less is short‑term.

Types of taxable stock income

Capital gains (realized on sale)

When you sell stock, your realized gain or loss equals sale proceeds minus cost basis (adjusted where applicable). If the difference is positive, you have a capital gain; if negative, a capital loss. Capital gains are taxed based on holding period: short‑term gains are taxed at your ordinary income tax rates; long‑term gains generally get preferential federal rates.

Dividends

Dividends are distributions from corporations to shareholders and are taxable in the year received (unless paid into tax‑advantaged accounts). Dividends are categorized as:

Qualified dividends: These meet IRS requirements (stock held for a specified holding period and paid by a U.S. corporation or eligible foreign corporation). Qualified dividends are taxed at long‑term capital gains rates (0%, 15%, 20% depending on income).
Ordinary (nonqualified) dividends: Taxed at ordinary income tax rates.

Whether a dividend is qualified depends on the underlying stock and how long you held it around the dividend date.

Return of capital and other adjustments

A return of capital (ROC) distribution reduces your cost basis instead of being taxed as dividend income until basis hits zero. Reinvested dividends (DRIPs) increase basis because you used distributions to buy additional shares. Stock splits change share count and per‑share basis but do not create taxable income by themselves.

Short‑term vs. long‑term capital gains

The key cutoff is one year. If you sell after holding more than 12 months, the gain is long‑term; 12 months or less is short‑term. Short‑term gains are taxed at ordinary federal income tax rates (the same brackets that apply to wages). Long‑term gains qualify for preferential federal rates that are typically lower.

How to calculate holding period: the day after you acquire the security is day one; count full days until the day you sell. Special rules apply for gifted or inherited assets (see below).

Federal capital gains tax rates (general framework)

Long‑term capital gains federal rates are generally 0%, 15%, or 20% depending on your taxable income and filing status. Short‑term gains are taxed at ordinary income rates (for example, typical federal rates range from 10% to 37% depending on bracket). These brackets and thresholds change over time, so always confirm current year rates with the IRS or tax software.

Example framework (illustrative only): for a given tax year, taxpayers with lower taxable incomes may pay 0% on long‑term gains, middle incomes 15%, and high incomes 20% plus any surtaxes. The exact taxable income thresholds that separate these brackets are set annually.

Additional federal taxes that may apply

Net Investment Income Tax (NIIT)

High‑income taxpayers may owe an additional 3.8% Net Investment Income Tax on the lesser of (a) net investment income or (b) the excess of modified adjusted gross income (MAGI) over certain thresholds (for single filers, $200,000; married filing jointly, $250,000; thresholds may change over time). NIIT applies to interest, dividends, capital gains, rental income, and other investment income.

Alternative Minimum Tax (AMT) and other interactions

The AMT can affect tax liabilities for certain taxpayers, although capital gains themselves do not automatically cause AMT; however, interactions exist and large gains or certain preference items can trigger AMT considerations. Consult a tax professional for complicated AMT situations.

State and local taxes

States vary. Many states tax capital gains and dividends as ordinary income at the state income tax rate. Some states have no income tax (so no state capital gains tax), while others may have special rules (e.g., lower rates or add‑backs). Localities may also impose taxes. Because state taxes can materially change the total tax on a sale, include them when estimating how much tax do you have to pay on stocks.

Calculating gain/loss and cost basis

Start with cost basis: typically the purchase price plus commissions and fees.
Adjust basis for return of capital, reinvested dividends, stock splits, and certain corporate actions.
Sale proceeds are the gross amount you receive, less commissions and selling expenses.
Realized gain or loss = sale proceeds (net) − adjusted basis.

Cost basis methods:

Specific identification (you tell your broker which lots you sold): gives most control over realized gain/loss.
FIFO (first in, first out): typical default for many brokers.
Average cost: allowed for mutual funds and some ETFs; rules differ.

When dividends are reinvested, each reinvestment increases your number of shares and basis accordingly; your broker’s 1099‑B or year‑end statement should show cost basis for covered lots.

Reporting and tax forms

Brokerage reporting (Form 1099‑B)

Brokerages issue Form 1099‑B that reports proceeds from sales and often cost basis for covered securities (acquired after specified dates). 1099‑B entries are grouped by whether the broker reports basis to the IRS. Review 1099‑B carefully; errors or missing basis entries may require taxpayer adjustments.

Tax forms taxpayers file (Schedule D, Form 8949, Form 1040)

Form 8949: Use to list individual sale transactions and adjustments when the basis reported on 1099‑B needs correction or for noncovered securities.
Schedule D: Summarizes totals of long‑ and short‑term gains and losses and carries totals to Form 1040.
Form 1040: Final tax return where capital gain/loss totals and dividend income are included in taxable income.

Keep copies of 1099‑B, trade confirmations, and brokerage statements to support figures on Form 8949 and Schedule D.

Timing and tax payment considerations

When taxes are due and estimated tax payments

Taxes on realized gains are due with your annual tax return. If you expect to owe a significant tax bill — for example, from large gains — you may need to make quarterly estimated tax payments to avoid underpayment penalties. Estimated payments use Form 1040‑ES schedules.

Withholding options and employer plans

Wage withholding does not automatically cover brokerage gains. Some taxpayers increase withholding on wages to cover expected investment tax or make estimated tax payments. Employer retirement accounts (401(k), 403(b)) and IRAs have different tax treatment (see section on tax‑advantaged accounts).

Common rules and exceptions

Wash sale rule

The wash sale rule disallows a loss on a sale if you buy a “substantially identical” security within 30 days before or after the sale (61‑day window including the sale date). Disallowed losses are added to the basis of the repurchased security, deferring the loss until disposition of the replacement. Wash sale rules apply across taxable accounts and IRAs in complex ways; loss disallowed by IRAs when you repurchase in an IRA cannot be added to basis.

Inherited stock (step‑up in basis)

Most inherited stocks receive a step‑up (or step‑down) in basis to their fair market value at the decedent’s date of death (or alternate valuation date). This means that gains accrued before death generally are not taxed to the heir; tax is due on appreciation after the date of inheritance when sold by the heir.

Gifted stock

Gifts carry over the donor’s basis for gain purposes in most cases (carryover basis). If the donor’s basis is greater than the current market value and the recipient sells at a loss, special dual‑basis rules apply. The recipient also inherits the donor’s holding period for determining short‑vs‑long‑term unless the basis rules provide otherwise.

Mutual funds and ETFs

Mutual funds and ETFs can distribute capital gains to shareholders annually even if you did not sell your shares; those distributions are taxable in the year received. Funds report these distributions on Form 1099‑DIV.

Retirement and tax‑advantaged accounts

Stocks held inside tax‑advantaged accounts (Traditional IRAs, Roth IRAs, 401(k)s, HSAs, 529s) are generally sheltered from current capital gains tax. Tax consequences occur on withdrawal depending on account type: traditional accounts typically tax withdrawals as ordinary income; Roth accounts offer tax‑free qualified withdrawals. If your goal is to minimize how much tax do you have to pay on stocks, placing tax‑inefficient investments (highly taxable dividends or short‑term trading) inside tax‑advantaged accounts can be an effective strategy.

Tax planning strategies to reduce or defer taxes

Tax‑loss harvesting

Sell losing positions to realize capital losses that offset realized capital gains. Net capital losses beyond gains can offset up to $3,000 of ordinary income per year ($1,500 married filing separately) with unused losses carried forward indefinitely. Beware of the wash sale rule when repurchasing similar securities.

Holding period management

Hold shares for more than one year when practical to access long‑term capital gains rates. Sometimes timing sales across the one‑year threshold can change tax rates materially.

Asset location (taxable vs. tax‑advantaged accounts)

Place tax‑inefficient assets (taxable bonds, REITs, high turnover funds) in tax‑advantaged accounts; keep tax‑efficient assets (index funds, tax‑managed funds) in taxable accounts.

Charitable giving, donor‑advised funds, gifting

Donate appreciated stock held long‑term directly to charity to avoid capital gains tax and claim a charitable deduction for the fair market value (subject to AGI limits). Donor‑advised funds enable timing of charitable deductions while distributing assets over time.

Partial sales and timing across tax years

Spread sales across tax years to manage taxable income and long‑term gain brackets. If long‑term capital gains push you into a higher bracket, spreading sales may keep you in a lower long‑term rate band.

Specialized strategies (advanced)

Qualified Opportunity Zone investments, installment sales, tax‑deferred exchanges (for real property), and other advanced strategies exist but require professional guidance and careful review of rules and timelines.

Examples and worked calculations (illustrative)

All numeric examples are illustrative. Check current year rates and thresholds before applying to your situation.

Example 1 — Short‑term gain taxed at ordinary rate:

Purchase: 100 shares at $50 on January 15, 2025 (basis $5,000).
Sale: 100 shares at $80 on June 15, 2025 (sale proceeds $8,000).
Holding period: ~5 months (short‑term).
Realized gain: $3,000.
Tax: $3,000 taxed at your ordinary federal tax rate (for example, at a 24% marginal rate ≈ $720 federal tax), plus any state tax. NIIT may apply if income is high.

Example 2 — Long‑term gain taxed at 15% (illustrative long‑term bracket):

Purchase: 100 shares at $20 on March 1, 2023 (basis $2,000).
Sale: 100 shares at $70 on April 1, 2025 (sale proceeds $7,000).
Holding period: >2 years (long‑term).
Realized gain: $5,000.
Tax: If your taxable income places you in the 15% long‑term capital gains bracket, federal tax ≈ $750, plus state tax.

Example 3 — Losses offsetting gains and ordinary income:

Realized short‑term gains during the year: $10,000.
Realized losses: $12,000.
Net capital loss: $2,000.
Up to $3,000 of net capital loss can offset ordinary income in the current year; remaining loss carries forward.

Example 4 — Wash sale adjustment (practical):

You bought 100 shares at $60 and later sold for $50 realizing a $1,000 loss. You then buy substantially identical shares within 30 days for $52.
The loss is disallowed under the wash sale rule; the $1,000 disallowed loss is added to the basis of the new shares (basis becomes $52 × 100 + $1,000 adjustment = $6,200). When you eventually sell those replacement shares, the deferred loss reduces or offsets future gain.

International and nonresident considerations

Nonresident aliens: U.S. source dividends paid to nonresident aliens are often subject to withholding (typically 30% unless a tax treaty reduces the rate). Capital gains of nonresident aliens on U.S. securities are generally not taxable by the U.S. unless effectively connected with a U.S. trade or business or except for certain real‑property–related gains. Tax treaties can change withholding rates and tax treatment; foreign investors should consult tax rules and brokers.

Foreign tax credits: If you pay foreign taxes on dividends or gains to a foreign jurisdiction, you may be eligible for a foreign tax credit to avoid double taxation on U.S. returns (subject to limitations).

Recordkeeping and documentation

Keep the following records at minimum:

Trade confirmations and monthly brokerage statements showing purchases and sales.
Year‑end consolidated 1099 (1099‑B, 1099‑DIV, 1099‑INT).
Records of DRIP purchases and reinvested dividends.
Documentation of gifts, inheritances, and any step‑up calculations.
Records of wash sale adjustments and basis computations.

Retain records for at least three years from the date you file the return (the IRS generally has three years to audit), but many recommend keeping basis and investment records for the life of the investment plus three years after sale.

Frequently asked questions (FAQ)

Q: Do I pay tax if I don't sell a stock? A: No — unrealized gains are not taxed in taxable accounts until you realize them by selling. However, mutual fund capital gain distributions are taxable when distributed even if you did not sell shares.

Q: How are dividends taxed? A: Qualified dividends are taxed at the long‑term capital gains rates (0/15/20% federal tiers); nonqualified dividends are taxed at ordinary income rates.

Q: What counts as a qualified dividend? A: It generally must be from a U.S. corporation or certain qualified foreign corporations, and you must meet a holding period requirement (typically more than 60 days during the 121‑day period beginning 60 days before the ex‑dividend date for common stock).

Q: How long to keep records? A: Keep trade confirmations and basis documentation while you hold the investment and for at least three years after sale. For basis issues related to inheritances or complex corporate actions, retain records longer.

Q: How much tax do you have to pay on stocks if you inherit them? A: Often very little initially because of the step‑up in basis to fair market value at death; you pay tax on gains accumulated after inheritance when you sell.

Sources quoted for market and retirement behavior: As of May 2025, The Motley Fool reported that Berkshire Hathaway’s marketable equity portfolio was roughly $315 billion and that the company had sold about $184 billion in net stock sales over the prior three years. As of December 2025, consumer finance outlets emphasized capturing 401(k) employer matches, minimizing fees, and evaluating Roth options when planning retirement savings.

Practical next steps (how to estimate your tax bill)

Gather trade confirmations and your brokerage 1099‑B and 1099‑DIV for the year.
Compute adjusted basis including reinvested dividends and any corporate action adjustments.
Separate short‑term and long‑term sales and calculate net gain/loss in each category.
Apply the appropriate federal long‑term or ordinary rates to estimated taxable gain; add potential 3.8% NIIT if your MAGI exceeds thresholds.
Add estimated state and local tax rates on the net gain or on your taxable income as applicable.
If you expect tax due, consider estimated tax payments or increasing withholding to avoid underpayment penalties.
