Pass Through Capital Gains Tax Guide – Pass-through capital gains tax refers to the taxation of capital gains generated by pass-through entities—such as partnerships, S corporations, and LLCs taxed as partnerships—that flow directly to owners’ personal tax returns. Unlike C corporations, these entities do not pay tax at the business level. Instead, gains pass through via Schedule K-1 and are taxed only once at the individual owner level using preferential long-term capital gains rates where applicable.
This guide explains how pass-through capital gains tax works for USA taxpayers in 2026, including reporting requirements, current rates, special rules, and strategies to minimize liability. All information draws from official IRS sources current as of 2026.
What Are Pass-Through Entities and How Do Capital Gains Pass Through?
Pass-through entities include partnerships (Form 1065), S corporations (Form 1120-S), and most LLCs. These businesses report income, deductions, and gains on an information return but pay no entity-level federal income tax.
When the entity sells a capital asset (e.g., real estate, stocks, or business equipment held for investment), any gain or loss passes through to owners. The entity issues each owner a Schedule K-1 showing their allocable share. Owners then report this on their individual Form 1040.
This single-layer taxation makes pass-through entities popular, but owners must track basis, at-risk rules, and passive activity limitations that may restrict deductible losses.
How Pass-Through Capital Gains Are Taxed at the Individual Level?
Pass-through capital gains receive the same tax treatment as gains from personally owned assets. The character (short-term or long-term) is determined at the entity level based on the holding period of the asset sold.
- Short-term capital gains (assets held one year or less) are taxed at ordinary income tax rates (up to 37% in 2026).
- Long-term capital gains (assets held more than one year) qualify for lower preferential rates of 0%, 15%, or 20%.
Gains increase your adjusted gross income and may trigger other taxes, such as the Net Investment Income Tax (NIIT).
2026 Long-Term Capital Gains Tax Rates for Pass-Through Income
Long-term capital gains from pass-through entities use the same brackets as other long-term gains. For taxable years beginning in 2026, the rates are:
| Filing Status | 0% Rate Applies (Taxable Income) | 15% Rate Applies | 20% Rate Applies |
|---|---|---|---|
| Single | $0 – $49,450 | $49,451 – $545,500 | Over $545,500 |
| Married Filing Jointly | $0 – $98,900 | $98,901 – $613,700 | Over $613,700 |
| Married Filing Separately | $0 – $49,450 | $49,451 – $306,850 | Over $306,850 |
| Head of Household | $0 – $66,200 | $66,201 – $579,600 | Over $579,600 |
These brackets are inflation-adjusted annually. Short-term gains and ordinary income fall into the regular tax brackets (10%–37%).
Special Capital Gains Categories from Pass-Through Entities
Certain gains reported on Schedule K-1 receive special rates:
- Collectibles (28%) gain (Box 9b or Box 20 Code AC): Taxed at a maximum 28% rate (e.g., art, coins, precious metals).
- Unrecaptured Section 1250 gain (Box 9c or Box 20 Code AD): Depreciation recapture on real property taxed at a maximum 25% rate.
These amounts flow to specific worksheets in the Schedule D instructions and are taxed at the lesser of the special rate or your ordinary rate.
How to Report Pass-Through Capital Gains on Your Tax Return?
- Receive Schedule K-1 — By the entity’s filing deadline (March 15 for partnerships/S corps, or extended date).
- Complete Form 8949 — Use if you have adjustments, basis differences, or to detail transactions not reported on a 1099-B.
- Transfer to Schedule D (Form 1040):
- Box 8 (net short-term) → Schedule D, line 5.
- Box 9a (net long-term) → Schedule D, line 12.
- Special gains → appropriate worksheets.
Totals from Schedule D flow to Form 1040. You may need to file Form 8949 even if the entity provides summary information.
Does the Qualified Business Income (QBI) Deduction Apply?
No. Capital gains and losses do not qualify as qualified business income (QBI) under Section 199A. The 20% QBI deduction applies only to ordinary trade or business income, not investment-type income such as capital gains, interest, or dividends.
Net Investment Income Tax (NIIT) on Pass-Through Capital Gains
High-income owners may owe an additional 3.8% NIIT on the lesser of:
- Net investment income (including pass-through capital gains), or
- The amount by which modified adjusted gross income (MAGI) exceeds the threshold.
2026 NIIT MAGI thresholds (unchanged by inflation):
- Single or Head of Household: $200,000
- Married Filing Jointly: $250,000
- Married Filing Separately: $125,000
State Taxes and Pass-Through Entity Taxes (PTET)
Most states tax pass-through capital gains at the owner level. Some states impose a PTET (entity-level tax) that owners can claim as a deduction or credit federally (subject to SALT limitations). Check your state rules, as they vary and interact with the federal $40,000 SALT cap (as expanded under recent legislation).
Strategies to Minimize Pass-Through Capital Gains Tax
- Hold assets longer than one year inside the entity to qualify for long-term rates.
- Use tax-loss harvesting within the entity or on your personal return to offset gains.
- Consider charitable contributions of appreciated assets (if allowed by entity agreement).
- Plan distributions and entity-level transactions around your overall tax bracket.
- Explore opportunity zone investments or qualified small business stock exclusions where available.
- Maximize basis adjustments and Section 179/ bonus depreciation where possible to reduce future gains.
Always document holding periods and consult a tax professional before year-end.
Common Mistakes to Avoid
- Forgetting to apply basis, at-risk, or passive loss limitations before claiming losses.
- Double-counting gains already reported on K-1.
- Missing special rate worksheets for collectibles or unrecaptured Section 1250 gain.
- Overlooking NIIT triggers on high investment income.
- Failing to file Form 8949 when required.
Recent Tax Law Updates (2025–2026)
The One Big Beautiful Bill Act (OBBBA) made the QBI deduction permanent and raised the federal SALT cap temporarily, benefiting owners in high-tax states with PTET elections. Capital gains brackets and NIIT thresholds continue annual inflation adjustments. No major changes altered the core pass-through mechanics for capital gains in 2026.
Frequently Asked Questions
Do I pay tax on pass-through capital gains even if no cash is distributed?
Yes. You are taxed on your share of the gain whether or not the entity distributes cash.
Can losses from the pass-through entity offset my other income?
Subject to basis, at-risk, and passive activity rules—losses may be limited or carried forward.
How do I know the holding period for entity-sold assets?
The entity determines it and reports the gain as short- or long-term on your K-1.
Are there differences for S corps vs. partnerships?
Reporting is similar (K-1), but S corps have stricter eligibility rules and potential built-in gains tax in early years after conversion from C corp status.
