Capital Account in a Private Fund: What LPs Actually See

A capital account is the limited partner's running book in a private fund or SPV: contributions in, allocations of profit and loss, distributions out. It is the number on the quarterly statement. It is not NAV, and it is not the partner's tax basis in the interest. LPs who treat those three as the same object misread both the report and the K-1.

This is general information, not tax or legal advice. Counsel and a tax adviser own your facts.

What a capital account in a private fund records

The capital account is a ledger for one partner. In a committed fund it runs for the life of the vehicle. In a single-asset SPV it usually runs from subscription through exit.

The book moves on four events:

• Contributions. Cash (or, less often, property) the LP actually funded, including capital calls against remaining commitment. Uncalled commitment is not capital until it is paid.

• Allocations of profit and loss. The LP's share of the vehicle's book P&L under the LPA or operating agreement — management fees, expenses, realized and unrealized investment results as the agreement defines them.

• Distributions. Cash or in-kind property paid to the LP. A distribution reduces the capital account; it is not a "return" until you compare it to paid-in capital and remaining value.

• Other adjustments. Equalization true-ups, transfers, forfeitures, and any special allocation the agreement requires.

The GP does not get to pick a number. The agreement sets how items hit the account. Fund administration is the function that keeps that ledger, produces the LP statement, and feeds the tax package.

Capital account vs NAV vs tax basis

LPs collapse three different objects into one email: "What is my balance?"

The IRS is explicit on the last two. The partnership must report beginning and ending capital on Schedule K-1, Item L, using the tax-basis method, including capital contributed, current-year tax P&L, withdrawals and distributions, and other increases or decreases determined in a manner generally consistent with sections 705, 722, 733, and 742, without regard to partnership liabilities. Ending capital in Item L may not equal the partner's adjusted tax basis, generally because outside basis includes the partner's share of partnership liabilities and because the partnership may not have partner-level information. The partner, not the fund, is responsible for tracking outside basis (IRS, Partner's Instructions for Schedule K-1 (Form 1065) (2025), Item L).

A quarterly statement that shows "ending capital" is almost always the book capital account under the LPA, not Item L and not outside basis. Do not wire a tax payment off the statement without the K-1.

What a quarterly capital-account statement shows

A competent LP pack, whether for a fund or an SPV, usually shows some version of this rollforward for each investor:

1. Beginning capital

2. Contributions during the period (with call dates)

3. Allocations of income, loss, fees, and expenses

4. Distributions during the period

5. Ending capital

6. Remaining unfunded commitment

7. Paid-in capital (cumulative contributions), often with cumulative distributions

Some administrators also print a vehicle NAV and the LP's percentage of it. That percentage is a reporting convenience. It is not a substitute for the capital account if the LPA allocates fees, carry, or expenses other than pro rata to commitments.

What the statement should match:

• The call notices and wires for the period

• The distribution notices

• The cap table (commitments and ownership)

• Year-end, the tax capital rollforward that feeds Schedule K-1 Item L, after book-to-tax differences

If those four do not reconcile, the LP is not looking at a bookkeeping difference. The administrator has two books that have drifted.

How contributions, allocations, and distributions hit the account

Contributions increase capital. A subscription at first close and a later capital call are the same economic event: cash in, remaining commitment down, capital account up. Property contributions are rarer in deal SPVs; when they happen, the agreement and tax rules (including built-in gain under section 704(c)) drive both the book capital and the K-1.

Allocations move capital without moving cash. Management fee, fund expense, and unrealized mark, if the LPA books marks, all change the account. An LP can have a lower capital account and the same unfunded commitment. That is not a call.

Distributions decrease capital. Under a European waterfall, early distributions may be 100% to LPs until contributed capital and any preferred return are back. Under an American / deal-by-deal waterfall, carry can come out earlier, which is why ending capital is a poor proxy for "what I am owed on exit." The waterfall lives in the agreement. The capital account records the result.

Carry is not a line the LP pays. Carried interest is an allocation (and later a distribution) to the GP or carry vehicle. It reduces what would otherwise sit in LP capital. If the statement does not show GP capital separately, ask for the partner-level rollforward, not a blended NAV.

Book capital, tax capital, and the K-1

Private funds keep at least two capital concepts:

• Section 704(b) / book capital. Used to determine who has economic risk and how the waterfall should behave. This is what LPs mean when they say "my capital account."

• Tax capital. What Item L reports. Book-tax differences (unrealized marks that are not yet taxable, fee timing, 704(c) amounts) make the two diverge, sometimes for the entire life of the fund.

Form 1065 is the partnership information return. The partnership generally does not pay federal income tax; partners may owe tax on their allocated share whether or not cash was distributed (IRS, Partner's Instructions for Schedule K-1 (Form 1065) (2025)). Item L is not a substitute for the outside-basis worksheet in those same instructions.

A GP who sends only a PDF NAV pie chart has not done capital-account reporting. A GP who sends a partner rollforward that ties to calls, distributions, and the year-end K-1 has.

Who maintains the capital account

The GP owns the economics in the LPA. The administrator maintains the record: subscriptions, calls, equalizations, fee accruals, marks the GP approved, waterfalls, and the LP statement. That split is the job of fund administration, not a valuation opinion.

On Allocations, fund administration is a published $19,500 per year engagement, with 0% platform carry. A Standard SPV is $9,950 one-time. Those are the published figures; they are not a capital-account methodology.

What LPs should ask for, in writing, once a year:

• Partner capital rollforward (beginning, contributions, allocations, distributions, ending)

• Remaining commitment

• Reconciliation of ending book capital to the K-1 Item L tax-basis capital, or a statement that the administrator will provide the recon with the tax package

• The valuation policy that feeds any unrealized allocation

If the fund has subsequent closings, the same ledger is where equalization catch-up and equalization interest land. That is a separate mechanic from an ordinary capital call; it still posts to the capital account.

A capital account is a bookkeeping object. Treat it that way. The statement is useful because it is reconcilable. It is not a performance promise, a redemption price, or tax advice.
