Capital accounts

A capital account is the partnership’s running tally of each partner’s economic stake. It goes up when you contribute money or property, or earn income, and down when you take distributions or absorb losses. It looks like bookkeeping, and it is, but it is the bookkeeping that everything else in partnership tax depends on. Special allocations are valid only if capital accounts are maintained correctly, and when the partnership winds up, the capital accounts decide who gets the money.

What goes in and what comes out

Each partner has a capital account, and it moves in four directions. It increases when the partner contributes cash or property, and when the partnership allocates them income or gain. It decreases when the partner takes a distribution, and when the partnership allocates them loss or deduction.

That is the whole mechanism, and it maps directly onto fairness. If you put in $100,000 and later take out $30,000, and the partnership allocated you $20,000 of income and $10,000 of loss along the way, your capital account is $80,000. It is a live measure of what you have in the deal, updated for everything that has happened.

A capital account is a partner’s live economic scorecard: contributions and income raise it, distributions and losses lower it.

Two kinds of capital account, and why the difference matters

Here is the piece that trips people up. There are two different capital accounts, kept on two different sets of rules, and real estate cares about both.

The 704(b) book capital account is the economic one, maintained under the Treasury regulations, and it can reflect the fair value of contributed property. This is the account that governs the substantial-economic-effect rules and, crucially, governs liquidation: when the partnership ends, it pays out according to positive 704(b) capital account balances. The tax basis capital account tracks each partner’s tax investment and is what the IRS now requires partnerships to report on Schedule K-1.

The two diverge whenever property is contributed at a value different from its tax basis, which in real estate is constantly, because appreciated property and depreciation drive them apart. Knowing which account governs which question, economics and liquidation from the 704(b) book account, tax reporting from the tax basis account, is a distinction that separates a well-run partnership from a mess.

There are two capital accounts: the 704(b) book account governs economics and liquidation, the tax basis account governs tax reporting, and in real estate they routinely differ.

Why the capital account is the linchpin

Everything sophisticated a partnership does runs through the capital account. Special allocations only have economic effect if capital accounts are maintained under the 704(b) rules and liquidation follows their positive balances. A partner’s ability to absorb losses is bounded by their economic stake, which the capital account tracks. Buyout pricing in many real estate agreements references capital account balances. Get the capital accounts wrong, and the special allocations you designed lose their validity, because the foundation they stand on is not there.

This is why the special allocations page and this one are two halves of one idea. The allocation is the instruction; the capital account is the ledger that proves the instruction had real economic effect. Neither works without the other.

Special allocations are valid only when the capital accounts underneath them are maintained by the 704(b) rules, so the ledger is what makes the allocation real.

The liquidation moment

The capital account’s biggest moment is the end. When a partnership liquidates, the 704(b) rules generally require it to distribute according to positive capital account balances. That is the payoff of maintaining them correctly all along: the money goes where the running scorecard says it should, which is the economic deal the partners actually struck. An agreement that instead liquidates on some other basis breaks the economic-effect rules and puts every special allocation in the deal at risk. The capital account is not a formality you reconcile at year end; it is the thing that decides who walks away with what.

The bottom line

• A capital account tracks each partner’s economic stake: up for contributions and income, down for distributions and losses.
• The 704(b) book account governs economics and liquidation; the tax basis account governs K-1 reporting.
• The two routinely diverge in real estate because of contributed property and depreciation.
• Special allocations are valid only if capital accounts are maintained under the 704(b) rules.
• At liquidation, distributions generally follow positive 704(b) capital account balances.
