do i have to file stock losses — U.S. tax guide

Do I Have to File Stock Losses?

As a starting answer to the common question do i have to file stock losses: yes — realized capital losses from selling stocks (and many digital assets treated as capital assets) generally must be reported on your U.S. federal income tax return. Paper (unrealized) losses are not reported. This article explains what counts as a reportable loss, when to report it, which IRS forms to complete, special rules (like wash sales and worthless securities), and practical recordkeeping and tax-planning tips. Expect step-by-step examples and an FAQ geared to beginners and investors using modern crypto tools like Bitget Wallet for tracking.

As of 2026-01-22, according to the IRS (Instructions for Schedule D and Form 8949), taxpayers must report sales and dispositions of capital assets on Form 8949 and Schedule D and follow updated digital-asset reporting guidance where applicable.

Overview of Capital Losses

• Definition: A capital loss occurs when you sell or dispose of a capital asset for less than your adjusted basis in that asset. Common capital assets include stocks, bonds, and many cryptocurrency tokens that the IRS treats as property.
• Realized vs. unrealized:
  • Realized loss: A loss that occurs when you actually sell or dispose of the asset. Realized losses are generally reportable on your tax return.
  • Unrealized (paper) loss: A drop in market value while you still hold the asset. Paper losses are not reported and do not create a tax deduction until realized.
• Typical capital assets: corporate stocks, ETFs, bonds, options, and many digital assets (cryptocurrencies) treated as property. Personal-use items and assets in most tax-advantaged accounts follow different rules (see “Transactions Not Reported / Not Deductible”).

The question do i have to file stock losses is fundamentally about realized losses — those you must track and report.

When You Must Report Losses

You must report a capital loss when any of these occur:

• You sell a stock, bond, ETF, or other capital asset for less than your adjusted basis (realized loss).
• A security becomes completely worthless during the tax year — the IRS treats this as if sold on the last day of the tax year; you must report the loss.

Exceptions or special cases:

• Assets inside tax-advantaged retirement accounts (IRAs, 401(k)s) are not reported as capital losses on Form 8949/Schedule D — losses inside these accounts generally do not produce deductible capital losses for current tax years.
• If you have trader tax status or use a mark-to-market election (Section 475), different reporting rules may apply and losses may be ordinary rather than capital.

Forms and Schedules to Use

Form 8949 — Sales and Other Dispositions of Capital Assets

• Purpose: List individual sales/dispositions of capital assets. You report each transaction with dates of acquisition and sale, proceeds, cost basis, adjustments, and gain or loss.
• Short-term vs. long-term: Complete separate Form 8949 sections for short-term (held one year or less) and long-term (held more than one year) transactions when required.
• Broker reporting: Your broker typically issues Form 1099-B with proceeds and may report whether basis was reported to the IRS. You must reconcile broker 1099-B information on Form 8949 when differences or adjustments exist.

Schedule D (Form 1040) — Capital Gains and Losses

• Purpose: Aggregate totals from Form 8949 and compute net capital gain or loss. Schedule D nets short-term gains/losses against short-term, long-term against long-term, then cross-nets to produce a net capital gain or loss amount.
• Result: Net capital gain flows to Form 1040 as taxable income; net capital loss may offset ordinary income up to limits (see next section).

Related Forms

• Form 1099-B / 1099-DA: Reporting from brokers or platforms. Many brokers send 1099-B for securities transactions. For digital-asset reporting, newer forms/codes have appeared; platforms may issue equivalent statements sometimes labeled 1099-DA or included in consolidated tax reporting.
• Form 8949 codes and reporting for digital assets: The IRS Instructions for Schedule D and Form 8949 have been updated in recent years to clarify digital-asset reporting; follow the latest instructions.
• Form 4797: For certain business or Section 1231 transactions (business property sales) where ordinary loss treatment may apply.
• Form 8997: For reporting certain corporate actions involving specified derivatives and basis adjustments (not typical for most retail investors).

Short-Term vs. Long-Term Losses

• Holding period rule:
  • Short-term: Held one year or less (365 days or fewer). Short-term gains/losses are taxed at ordinary-income tax rates.
  • Long-term: Held more than one year. Long-term gains/losses receive long-term capital gain treatment (preferential tax rates for gains).
• Netting process:
  • First, net short-term gains against short-term losses and long-term gains against long-term losses.
  • Then, net the resulting short-term and long-term amounts against each other to reach a final net capital gain or loss reported on Schedule D.

How Losses Offset Gains and Income

• Losses first offset capital gains in the same tax year.
• If capital losses exceed capital gains, you can deduct up to $3,000 of net capital loss against ordinary income each tax year ($1,500 if married filing separately).
• Any unused loss beyond the $3,000 annual deduction carries forward to future years indefinitely until used.

Illustration: If you have $10,000 of capital gains and $15,000 of capital losses in a year, you first offset the $10,000 gains fully, leaving $5,000 net capital loss. You can deduct $3,000 of that loss against ordinary income in the current year, and the remaining $2,000 carries forward.

Carryovers of Unused Losses

• Carryforward rule: Net capital losses that exceed the annual $3,000 offset carry forward to subsequent tax years until exhausted.
• Tracking carryforwards: The Schedule D instructions and tax software maintain a running total of unused loss carryovers. Keep records of the original loss year, amounts used, and remaining balance.
• No time limit: Carryovers continue indefinitely until fully applied.

The Wash Sale Rule

• Basic rule: The wash sale rule disallows a loss deduction if you acquire substantially identical stock or security within 30 days before or after the sale that generated the loss (a 61-day window including the sale date).
• Disallowed loss adjustment: A disallowed loss is added to the basis of the repurchased shares, effectively deferring the loss until the replacement shares are sold.
• Substantially identical: The IRS standard applies to stocks and securities. Interpretation for similar securities (e.g., different classes of the same company) can be complex.
• Cryptocurrency and wash sales: As of the current IRS guidance, cryptocurrencies are treated as property, and wash-sale rules historically apply to stocks and securities. There is ongoing discussion about whether wash-sale rules apply to crypto transactions; taxpayers should exercise caution, consult IRS updates, and discuss specifics with a tax professional. For retail investors using crypto, assume rules may change and keep careful records.

Practical tip: If you sell a stock at a loss and want to maintain market exposure, consider waiting more than 30 days to repurchase the same or substantially identical security, or buy a similar but not substantially identical security to avoid the wash-sale rule.

Worthless Securities and Abandonment

• Worthless securities: If a security becomes completely worthless during the year, treat it as if sold on the last day of the tax year for determining a capital loss.
• Documentation: Keep evidence that the security became worthless (company bankruptcy filings, delisting notices, or company communications).
• Abandonment: In limited situations where you abandon property, loss treatment can differ; consult a tax professional for abandonment claims.

Digital Assets (Cryptocurrency) — Special Considerations

• Tax classification: The IRS treats most cryptocurrencies as property, so sales, exchanges, and dispositions create capital gains or losses when realized.
• Reporting: Transactions involving digital assets that result in gain or loss should be reported on Form 8949 and Schedule D like other capital assets. Exchanges or brokers may issue reporting statements (1099-B or similar), and some platforms have added digital-asset-specific reporting forms or consolidated statements.
• New reporting codes and forms: The IRS and broker-dealers have updated reporting practices in recent years. As of 2026-01-22, taxpayers should consult the latest Instructions for Form 8949 and Schedule D for digital-asset-related codes and reporting mechanics.
• Wash-sale treatment for crypto: Current IRS guidance historically applies wash-sale rules to securities; because crypto is property, the application of the wash-sale rule to crypto has been debated and subject to evolving interpretations. Until explicit IRS regulation states otherwise, treat crypto transactions carefully and record them precisely. Consult a tax professional for complex or high-volume crypto trading.
• Tracking cost basis: Crypto wallets and platforms do not always report basis accurately. Use reliable transaction exports, wallet software, or a dedicated portfolio tracker. Bitget Wallet offers transaction export and portfolio tracking features to help gather the information needed for Form 8949.

Transactions Not Reported / Not Deductible

• Retirement accounts: Losses inside IRAs, 401(k)s, and many employer plans are not deductible on your personal tax return.
• Personal-use property: Losses on personal-use property (like a car used for personal reasons) are generally not deductible as capital losses.
• Inventory/business property: Assets held for sale to customers or inventory are not capital assets. Business inventories and ordinary business losses follow different tax treatments.

Documentation and Recordkeeping

Good documentation is essential to support reported losses and respond to IRS inquiries. Maintain the following for each transaction:

• Trade confirmations and transaction receipts.
• Broker Form 1099-B or consolidated statements and any digital-asset reports (e.g., 1099-DA if provided).
• Dates of acquisition and sale, proceeds, fees, and cost basis calculations.
• Records of corporate actions (splits, mergers) affecting basis.
• For crypto: wallet addresses, transaction IDs, exchange withdrawal/deposit records, and CSV exports of trades. Bitget Wallet users can export transaction histories to help calculate cost basis and prepare Form 8949 entries.

Keep records for at least three years after filing, but consider retaining basis records for as long as you hold an asset plus several years beyond that because carryforwards and audits can require older data.

How to Report — Step-by-Step Example

Here is a simplified workflow that illustrates reporting a loss on a stock sale.

1. Collect documents: Obtain your broker Form 1099-B and any digital-asset reports. Export wallet or platform transaction histories for crypto holdings.
2. Identify each sale: For each sale that realized a loss, note acquisition date, sale date, proceeds, cost basis, and holding period.
3. Complete Form 8949: Enter individual transactions on Form 8949. Use separate parts/columns for transactions where basis was reported to the IRS and those where it was not. Mark any necessary adjustment codes (e.g., for wash sale disallowance) and show adjustments to gain/loss.
4. Transfer totals to Schedule D: Aggregate short-term and long-term totals from Form 8949 to Schedule D. Net amounts as required.
5. Apply annual limits: If you end with a net capital loss, apply up to $3,000 against ordinary income and carry forward the remainder.
6. File Form 1040: Enter the Schedule D result on your Form 1040 as required.

Example: You bought Stock A for $12,000 and sold it after eight months for $8,000. Realized loss = $4,000 (short-term). If you have no other gains, you could deduct $3,000 against ordinary income this year and carry forward $1,000 to next year.

State Tax Considerations

• State treatment varies. Many states follow federal definitions and limits for capital gains and losses, but some have differences in deduction limits, carryover rules, or treatment of crypto.
• Check your state revenue department guidance or consult a tax professional if your state has unique rules.

Penalties, Audits, and Common Mistakes

• Failure to report: Not reporting realized capital transactions can lead to notices, penalties, and interest if the IRS detects discrepancies between broker-reported 1099s and your return.
• Mismatches: Common audit triggers include mismatches between broker-reported Forms 1099-B and amounts reported on Form 8949/Schedule D.
• Common errors:
  • Using incorrect cost basis (e.g., failing to include fees or missing adjustments).
  • Ignoring wash-sale disallowances.
  • Forgetting to report crypto trades that involve exchanges between different tokens.
• Penalties: The IRS can assess penalties for underpayment and failure to file accurate returns; interest accrues on unpaid tax.

Tax Planning Strategies

H3: Tax-Loss Harvesting

• What it is: Tax-loss harvesting is selling securities at a loss to offset realized gains and reduce current-year tax liability.
• How to use it: Harvest losses to offset gains; if you have net losses, realize up to $3,000 of them against ordinary income and carry forward the rest.
• Caution: Avoid wash-sale issues by observing the 30-day rule before repurchasing substantially identical securities.
• Crypto nuance: Because regulatory guidance on wash-sale application to crypto is evolving, consider non-identical assets or wait periods, and document your decisions.

H3: Timing Sales and Year-End Considerations

• Year-end planning: Many investors review portfolios near year-end to harvest losses or realize gains strategically.
• Holding periods: When close to the one-year holding threshold, consider whether to hold an extra day to qualify for long-term treatment (if the gain is expected) or to sell sooner if a short-term deduction suits other planning goals.

When to Consult a Tax Professional

Seek professional help when any of these apply:

• Large or complex loss carryovers spanning many years.
• Complex wash-sale chains from frequent trading.
• High-frequency trading or suspected trader tax status and Section 475 considerations.
• Extensive or complicated crypto transaction histories across multiple wallets and platforms.
• Cross-border or multi-state tax issues.

A tax professional can also advise on elections, such as mark-to-market, and assist with audit representation.

Frequently Asked Questions (FAQ)

Q: Do I have to report paper losses? A: No. Unrealized (paper) losses are not reported. Only realized losses from sales or dispositions are reported on Form 8949 and Schedule D.

Q: Can I deduct losses from trading as a business? A: Typically, individual investors report capital losses, not ordinary losses. Traders who qualify for trader tax status or who elect mark-to-market accounting under Section 475 may have different treatment. Consult a tax professional for trader-status qualification.

Q: Are crypto losses deductible? A: Generally, yes — the IRS treats most crypto as property, so realized crypto losses are reported on Form 8949/Schedule D. However, treatment of wash-sale rules for crypto has been debated and may evolve; consult current IRS guidance.

Q: What happens if my broker reports a transaction and I don't? A: The IRS receives copies of certain broker reports (e.g., Form 1099-B). A mismatch can trigger notices. Always reconcile broker reports with your return and reach out to brokers for any discrepancies.

Q: How do I compute cost basis if I received shares from corporate actions? A: Corporate actions (splits, mergers, spin-offs) can affect basis; brokers generally provide basis information for many corporate actions but verify and keep supporting documentation.

Q: Where does the phrase do i have to file stock losses fit in my tax planning? A: It encapsulates whether realized losses must be filed — yes, you must file realized losses, and you should use this guide to walk through reporting, wash-sale considerations, and carryovers.
