How to Report Carried Interest on Your Tax Return

To report carried interest on your tax return, start with the Schedule K-1 the partnership sends you, apply the Section 1061 three-year holding period test on Worksheet B to figure out how much of your long-term capital gain must be reclassified as short-term, and record the adjustment through two offsetting entries on Form 8949 that carry into Schedule D and then Form 1040. Management fees and guaranteed payments from the same partnership follow a different path through Schedule E. The reclassification calculation is the step that trips people up, and it is the difference between a top rate of 20% and a top rate of 37% on the gain that fails the three-year test.

Start With Your Schedule K-1

The Schedule K-1 (Form 1065) from the partnership is where your reporting begins. It contains your share of partnership income, deductions, and credits for the year.¹

The Section 1061 information is flagged in a specific place depending on the entity type. On a partnership K-1 (Form 1065), look for Box 20, Code AM. On an S corporation K-1 (Form 1120-S), it appears in Box 17, Code AD. On an estate or trust K-1 (Form 1041), it’s in Box 14, Code Z.²

The critical information is not in the main boxes alone. Partnerships applying the final regulations under TD 9945 must attach Section 1061 Worksheet A to your K-1. Worksheet A reports two figures you will need: your API one-year distributive share amount (gains from partnership assets held more than one year) and your API three-year distributive share amount (gains from assets held more than three years). The difference between those two numbers drives everything that follows.²

Do not simply copy the long-term capital gain from Box 8 of your K-1 onto Schedule D. Box 8 reports total long-term gain using the standard one-year threshold. The three-year reclassification is your responsibility as the owner taxpayer unless the partnership has already made the adjustment and clearly indicated so.

If your K-1 arrives without Worksheet A, or without the holding period breakdown you need, ask the partnership for it. Without that data, the conservative fallback is to treat all the gain as subject to the three-year rule, which reports more income as short-term and overpays your tax but avoids an audit fight.

Run the Three-Year Test on Worksheet B

Section 1061 requires that gains allocated to you through an applicable partnership interest pass a three-year holding period test before they qualify for long-term capital gains rates. Gains from assets the partnership held for three years or less get reclassified as short-term capital gain on your return, even when the partnership held those assets for more than a year.³

The IRS provides Section 1061 Worksheet B for the actual calculation.⁴ The math walks through three steps:

One-year gain amount. Take your API one-year distributive share amount from Worksheet A and add any gain from dispositions of applicable partnership interests you held more than one year. If the total is zero or negative, nothing gets reclassified and you can stop.
Three-year gain amount. Take your API three-year distributive share amount from Worksheet A and add gain from dispositions of interests you held more than three years.
Recharacterization amount. Subtract the three-year gain from the one-year gain. The result is the amount that shifts from long-term to short-term.

A quick example. Your K-1 shows $500,000 in long-term capital gain, but only $200,000 came from assets held longer than three years. The recharacterization amount is $300,000. That $300,000 moves from long-term to short-term on your return and gets taxed at ordinary rates.⁴

Worksheet B also picks up any Section 1061(d) recharacterization from transfers to related persons on line 8. The final adjustment lands on line 9, and that is the number you carry to Form 8949.

Enter the Adjustment on Form 8949 and Schedule D

The recharacterization does not flow directly onto Schedule D. It goes through Form 8949 as two offsetting entries.²

On Form 8949, Part I (short-term transactions), add a line described as “Section 1061 Adjustment” in column (a). Enter the recharacterization amount from Worksheet B line 9 as proceeds in column (d), and zero as basis in column (e). This adds the recharacterized amount to your short-term capital gain.

On Form 8949, Part II (long-term transactions), make the mirror entry: “Section 1061 Adjustment” in column (a), zero as proceeds in column (d), and the recharacterization amount as basis in column (e). This removes the same amount from your long-term capital gain.²

From there, the Form 8949 totals feed Schedule D in the normal way. Part I totals populate the short-term section of Schedule D, Part II totals populate the long-term section, and the net capital gain or loss flows to Form 1040, line 7a.⁵

Keep Management Fees on Schedule E

The capital gain portion of carried interest is only part of what shows up on a fund manager’s K-1. Management fees and guaranteed payments appear as ordinary business income in Box 1 and go on Part II of Schedule E.⁶

Keep these two income streams separate. Capital gains from carried interest flow through Form 8949 and Schedule D. Ordinary service income flows through Schedule E. Mixing them changes your tax liability and invites IRS scrutiny, because the agency matches your entries against the K-1 data the partnership files directly.

The mix matters for self-employment tax too. Capital gains, including any carried interest gains reclassified as short-term, are excluded from net earnings from self-employment under Section 1402(a).⁷ Reclassification changes your income tax rate on the gain but does not pull it into Schedule SE. Management fees and guaranteed payments are ordinary income for services and do carry self-employment tax.

What Falls Outside the Three-Year Rule

Not every dollar on your K-1 is subject to Section 1061. Three exclusions matter for reporting:

Capital interests. If your partnership interest gives you a right to share in partnership capital proportionate to the capital you contributed, that portion is not an applicable partnership interest. Return attributable to your own invested capital follows the normal one-year holding period.³
Corporate holders. A partnership interest held directly or indirectly by a corporation falls outside Section 1061 entirely.³
Section 1231 property. Gains from Section 1231 property, generally depreciable business-use real estate and similar assets held longer than one year, are excluded from Section 1061. Real estate fund managers whose portfolios consist of rental property held for income see meaningful protection here. The exclusion covers gain from the partnership’s sale of the underlying Section 1231 asset, not gain from selling your profits interest itself.

If you invest your own money alongside carrying a profits interest, the K-1 attachments should separate the capital interest gain from the API gain so each is reported under the correct holding period rule.

Transfers to Related Persons Still Trigger the Rule

Gifting or transferring your carried interest to a family member or a colleague does not sidestep the three-year test. Under Section 1061(d), transferring an applicable partnership interest to a related person requires you to include as short-term capital gain any long-term gain attributable to assets held three years or less that is allocable to the transferred interest.³

A “related person” includes family members under the Section 318 attribution rules and anyone who performed services in the same applicable trade or business during the current calendar year or the preceding three. That second category catches transfers between colleagues at the same fund. Gain triggered by the transfer is added to your Worksheet B calculation on line 8.

Net Investment Income Tax

Carried interest income may also draw the 3.8% Net Investment Income Tax. The NIIT applies to the lesser of your net investment income or the amount by which your modified adjusted gross income exceeds the applicable threshold:⁸

Married filing jointly or qualifying surviving spouse: $250,000
Single or head of household: $200,000
Married filing separately: $125,000

These thresholds are not inflation-adjusted. You report the NIIT on Form 8960.⁹

Whether NIIT applies to your carried interest turns on how active you are in the partnership’s business. Capital gains are generally net investment income, but an exception exists for income earned in the ordinary course of a trade or business in which the taxpayer materially participates. Fund managers deeply involved in investment decisions sometimes take the position that their carried interest gain falls within this exception. The IRS has historically read the exception narrowly, and this is an area where professional tax advice pays for itself.

State Tax Reporting Can Diverge

Many states do not conform to Section 1061. In a non-conforming state, the amount you reclassified as short-term on your federal return may still be long-term for state purposes, which means running two calculations on the same income: one for federal Schedule D and one for your state return. Some states go the other direction with their own carried interest provisions or tax all capital gains at ordinary rates regardless of holding period. Check your state’s conformity before assuming the federal characterization carries through.

Penalties for Reporting It Wrong

Treating reclassifiable gain as long-term when Section 1061 required short-term treatment creates an underpayment the IRS can penalize. The accuracy-related penalty under Section 6662 is 20% of the underpayment attributable to negligence, disregard of tax rules, or a substantial understatement of income tax.¹⁰

For individuals, an understatement is “substantial” if it exceeds the greater of $5,000 or 10% of the tax that should have been shown. Carried interest numbers usually clear that bar without difficulty. The penalty rate rises to 40% for gross valuation misstatements.¹⁰

A reasonable cause defense is available if you can show good faith and a reasonable basis for your position. Keeping Worksheet A from the partnership, completing Worksheet B, and documenting your holding period analysis all support that defense. Ignoring the K-1 attachments and skipping the adjustment entirely is hard to defend.
