A statement of owner’s equity is a short financial report that shows how the owner’s stake in a business changed over an accounting period, and it’s built from a single formula: beginning equity, plus new contributions, plus net income, minus owner draws, minus any net loss, equals ending equity. It sits between your income statement and your balance sheet. The income statement feeds it a net income or loss figure; the ending equity it produces flows straight into the equity section of the balance sheet. Sole proprietors usually call it an owner’s equity statement, partnerships call it a partner’s equity statement, and corporations prepare a statement of stockholders’ equity with extra components like dividends and stock transactions.
What the Statement Actually Tracks
Every statement begins with the beginning capital balance, which is just the ending equity from the prior period. In the first year of a business, it’s whatever the owner originally put in. Four kinds of changes move that number up or down during the period:
- Owner contributions. Cash, equipment, or other personal assets the owner puts into the business. These increase equity.
- Net income. Profit after all expenses. Comes straight from the income statement. Increases equity.
- Net loss. When expenses exceed revenue. Reduces equity.
- Owner draws. Cash or assets the owner pulls out for personal use. Reduces equity. Draws are not business expenses. Withdrawing $5,000 or $50,000 has no effect on taxable business income, because draws are distributions of profit, not deductions against it.
The ending balance after applying those four items becomes the beginning balance for the next period. If the books are continuous, the figure carries itself forward.
How to Prepare It
You need four numbers, and each one lives in a specific place.
Beginning equity. Pull it from the previous period’s balance sheet, or from the opening entries in your general ledger.
Net income or net loss. Take it from a finalized income statement for the period. The income statement has to be complete first, because everything downstream depends on that figure being right.
Owner contributions. Find them in the owner’s capital account in the general ledger, and cross-check against bank deposit records to confirm amounts and dates.
Owner draws. Find them in the draw account in the general ledger, and cross-check against bank statements and withdrawal records.
Cross-referencing the ledger against the bank is where most errors surface. A contribution recorded in the books but missing from the bank statement, or a withdrawal that hit the bank but never got entered, will throw the ending equity off. Catching those before you finalize the statement is much easier than explaining them later.
Once you have the four numbers, apply the formula in order: begin with beginning equity, add contributions, add net income (or subtract net loss), subtract draws. The result is the ending equity. That figure moves to the balance sheet, and the balance sheet balances only if this statement was calculated correctly.
A Worked Example
Say you started the year with $80,000 in equity. You contributed another $10,000 in cash, the business earned $45,000 in net income, and you took $30,000 in draws over the year. The ending equity is $105,000.
The value of the statement is in what it shows beyond the final number. A business that ended the year with more equity than it started with could have gotten there through profit, through the owner putting cash in, or both. This statement tells you which one happened. When a lender asks whether the business is self-sustaining, or when you’re trying to see whether operations actually generated wealth, that breakdown is the whole point.
Why the Draws vs. Expenses Line Matters
The single most common mistake on an equity statement is classifying an owner draw as a business expense. It’s also the mistake with the clearest tax consequences.
For a sole proprietor, draws themselves are not taxed when you take them. Your entire net business income gets reported on Schedule C of your personal return, and you owe income tax and self-employment tax on that profit no matter how much you actually withdrew. The self-employment tax rate is 15.3%, combining 12.4% for Social Security and 2.9% for Medicare.1Social Security Administration. Contribution and Benefit Base An additional 0.9% Medicare surtax applies to self-employment income above $200,000, or $250,000 on a joint return.2GovInfo. 26 USC 1401 – Rate of Tax
Because the tax attaches to net income and not to the withdrawal, misclassifying a draw as an expense understates net income and understates the tax owed. The equity statement has to keep draws and expenses cleanly apart for the return to be right.
S corporation owners face a related but different question. Distributions from an S corporation are not subject to self-employment tax, but the IRS requires shareholder-employees to pay themselves reasonable compensation as wages before taking distributions, and courts have reclassified distributions as wages when a shareholder-employee took little or no salary.3Internal Revenue Service.

Partnerships Have an Extra Layer
If you’re preparing this for a partnership, the same statement logic applies, but you also feed the numbers into Schedule M-2 on Form 1065, which analyzes changes in partners’ capital accounts during the tax year. Each partner’s Schedule K-1 then reports that partner’s beginning capital, contributions, share of income or loss, withdrawals and distributions, and ending capital.5Internal Revenue Service. 2025 Instructions for Form 1065 – US Return of Partnership Income
A few details catch partnerships out. Capital contributed during the year means cash plus the adjusted tax basis of contributed property, reduced by any liabilities the partnership assumes. Withdrawals and distributions follow the same logic in reverse. Guaranteed payments to partners need to be backed out of the net income line on Schedule M-2 so they aren’t double-counted. And the ending capital account on a K-1 won’t necessarily match a partner’s adjusted tax basis in the partnership interest, because the capital account excludes the partner’s share of partnership liabilities.5Internal Revenue Service. 2025 Instructions for Form 1065 – US Return of Partnership Income
How Long to Keep the Records
Federal law requires anyone liable for tax to keep records sufficient to support the return.6Office of the Law Revision Counsel. 26 USC 6001 – Notice or Regulations Requiring Records, Statements, and Special Returns For the equity statement and its supporting ledgers and bank records, the IRS retention periods are:
- Three years for records supporting income, deductions, or credits on a filed return.
- Six years if you failed to report income exceeding 25% of the gross income on the return.
- Four years for employment tax records, measured from the later of the tax due date or the payment date.
- Indefinitely if you didn’t file, or filed a fraudulent return.
Electronic records are acceptable, but the IRS expects the storage system to preserve a complete and accurate transfer of the original documents, include controls against unauthorized alteration or deletion, and maintain a cross-referenced audit trail from the general ledger to source documents. You also have to be able to produce legible hard copies on request during an examination.8Internal Revenue Service. Revenue Procedure 97-22 – Electronic Storage Systems for Books and Records
Prepare the statement after the income statement is closed and before the balance sheet is finalized. Keep the supporting ledger detail, the bank statements you reconciled against, and the prior period’s ending equity together in one place. If the return is ever examined, that chain is what shows the numbers.
