What’s New in the 2025 IRS Schedule D Instructions?

The IRS regularly updates its forms and instructions to reflect changes in tax law, and 2025 is no exception. Here are the key updates:

  • New Codes for Digital Asset Transactions: Six new codes (G, H, I, J, K, and L) have been added to lines 1b, 2, 3, 8b, 9, and 10 of Schedule D. These are specifically for reporting transactions involving digital assets. Corporations should refer to Form 1099-DA (Digital Asset Proceeds From Broker Transactions) and Form 8949 (Sales and Other Dispositions of Capital Assets) for more details on handling digital asset sales, exchanges, or dispositions.
  • Deferral of Gain Invested in a Qualified Opportunity Fund (QOF): If your corporation elected to defer gains by investing in a QOF and has met the 7-year holding period, you may qualify for a basis adjustment. Check Form 8997 (Initial and Annual Statement of Qualified Opportunity Fund Investments) for guidance on QOF investments and related reporting.

These changes reflect the growing role of digital assets in corporate portfolios and ongoing incentives for opportunity zone investments. Staying informed about these updates can help avoid penalties and maximize tax benefits.

Purpose of IRS Schedule D (Form 1120)

Schedule D (Form 1120) is designed to help corporations calculate and report their capital gains and losses. Specifically, use this schedule to:

  • Report the overall gain or loss from transactions listed on Form 8949.
  • Document certain transactions not required on Form 8949.
  • Include gains from Form 6252 (Installment Sale Income) or Part I of Form 4797 (Sales of Business Property).
  • Report gains or losses from Form 8824 (Like-Kind Exchanges).
  • Account for any unused capital loss carryovers.
  • Report capital gain distributions not directly entered on Form 1120 (line 8) or equivalent lines on related forms like Form 1120-F or 1120-C.

This form ensures that capital transactions are properly aggregated and integrated into your overall corporate tax return, affecting your taxable income.

Who Must File Schedule D (Form 1120)?

Not every corporation needs to file Schedule D, but it’s required if you have capital gains or losses to report. Attach it to your main tax return if you’re filing:

  • Form 1120 (U.S. Corporation Income Tax Return)
  • Form 1120-C (U.S. Income Tax Return for Cooperative Associations)
  • Form 1120-F (U.S. Income Tax Return of a Foreign Corporation)
  • Form 1120-FSC (U.S. Income Tax Return of a Foreign Sales Corporation)
  • Form 1120-H (U.S. Income Tax Return for Homeowners Associations)
  • Form 1120-IC-DISC (Interest Charge Domestic International Sales Corporation Return)
  • Form 1120-L (U.S. Life Insurance Company Income Tax Return)
  • Form 1120-ND (Return for Nuclear Decommissioning Funds and Certain Related Persons)
  • Form 1120-PC (U.S. Property and Casualty Insurance Company Income Tax Return)
  • Form 1120-POL (U.S. Income Tax Return for Certain Political Organizations)
  • Form 1120-REIT (U.S. Income Tax Return for a Real Estate Investment Trust)
  • Form 1120-RIC (U.S. Income Tax Return for Regulated Investment Companies)
  • Form 1120-SF (U.S. Income Tax Return for Settlement Funds)
  • Certain Forms 990-T (Exempt Organization Business Income Tax Return)

If your corporation has no capital transactions, you generally don’t need to file this schedule. However, consult a tax professional if you’re unsure.

Completing Schedule D often involves coordinating with other IRS forms. Here’s a quick overview:

  • Form 8949: Use this to detail individual sales or exchanges of capital assets, including nonbusiness bad debts, undistributed long-term gains from Form 2439, and QOF-related transactions. Complete Form 8949 before entering totals on Schedule D lines 1b, 2, 3, 8b, 9, or 10.
  • Form 4797: For sales of business property, involuntary conversions, or section 1231 gains deferred into a QOF.
  • Form 4684: To report gains or losses from casualties and thefts.
  • Form 6781: For gains and losses from section 1256 contracts and straddles.
  • Form 8824: For like-kind exchanges; transfer the gain or loss to Schedule D line 5 or 13.
  • Form 8997: Required if you held a QOF investment during the year.

Understanding Capital Assets and Losses

What Qualifies as a Capital Asset?

Most property held by a corporation is considered a capital asset, unless it’s inventory, accounts receivable, depreciable business property, copyrights, or certain other exceptions. You can elect to treat certain musical compositions or copyrights as capital assets under section 1221(b)(3).

Handling Capital Losses

Capital losses can only offset capital gains in the current year. Any net capital loss can be carried back 3 years or forward up to 5 years as a short-term loss. Special rules apply for foreign expropriation losses (forward up to 10 years) and regulated investment companies (RICs), which have no limit on forward carryovers. Carrybacks can’t create or increase a net operating loss.

Short-Term vs. Long-Term Gains/Losses

  • Short-Term: Holding period of 1 year or less; report in Part I of Schedule D.
  • Long-Term: Holding period over 1 year; report in Part II.

Specific Instructions for Completing Schedule D

Schedule D is divided into parts for short-term and long-term transactions, totals, and built-in gains.

Part I: Short-Term Capital Gains and Losses

Report assets held 1 year or less. Include totals from Form 8949 (lines 1b, 2, 3), gains from Forms 6252/4797/8824, and any unused loss carryovers.

Part II: Long-Term Capital Gains and Losses

For assets held more than 1 year. Similar to Part I, include Form 8949 totals (lines 8b, 9, 10), other gains, and capital gain distributions.

Part III: Summary of Parts I and II

Combine net short- and long-term gains/losses here to determine overall capital gain or loss.

Part IV: Tax Computation Using Maximum Capital Gains Rates

Applies if there’s a net capital gain; calculate tax at preferential rates.

Built-in Gains Tax

Certain corporations (e.g., former S corporations) may owe built-in gains tax under section 1374. Calculate using the worksheet in the instructions and report on Schedule D.

Special Rules and Items for Special Treatment

The instructions cover numerous special scenarios, including:

  • Digital Assets: Report all transactions, even without a 1099 form.
  • Installment Sales: Use Form 6252 unless electing out.
  • Wash Sales: Losses disallowed; report on Form 8949 with code “W”.
  • Passive Activities: May require Form 8810 for limitations.
  • Exclusions for DC Zone or Qualified Community Assets: Limited exclusions for gains from assets acquired in specific periods (pre-2012 for DC Zone, pre-2010 for community assets).
  • Constructive Sales and Ownership: Treat certain gains as ordinary income.

For examples and worksheets (e.g., for basis adjustments or loss limitations), refer directly to the IRS instructions or Pub. 544.

Tips for Compliance and Filing

  • Always use the basis rules under sections 1012–1091 when calculating gains/losses.
  • Attach explanations for any non-cost basis.
  • File electronically if possible to reduce errors.
  • Consult Pub. 542 (Corporations) for additional corporate tax insights.
