Sole proprietorship balance sheet: owner equity

A sole proprietorship balance sheet shows the business's assets, liabilities and owner equity on a particular date. Owner contributions and draws belong in the equity reconciliation, so they must be separated from revenue and operating expenses.

Define the business reporting boundary

The IRS recordkeeping guide describes a balance sheet as the assets, liabilities and equity of a business on a given date. It also recommends keeping a business checking account separate and identifying deposits as business income, owner funds or loans.

This example is an operating report for a business run by a sole proprietor. It excludes the owner's household assets and obligations. Keep the reporting boundary consistent even though a sole proprietorship is not legally separate from its owner.

Use the same accounting basis at both dates. The example below uses accrual records, so unpaid customer invoices and unpaid supplier bills are included. A bank cashbook alone cannot supply those balances. For the full statement structure, see the balance sheet guide.

Owner equity = Business assets - Business liabilities

Closing owner equity = Opening owner equity + Contributions + Net income - Draws

A net loss enters the second formula as a negative amount. This example has no other direct equity adjustments.

A worked business balance sheet

Cedar Field Service is a fictional US industrial repair business operated as a sole proprietorship. Its bookkeeper compares December 31, 2025, with December 31, 2026. All figures are USD, shown without rounding.

The asset export contains the following balances. Equipment is shown at historical cost, with accumulated depreciation as a separate deduction.

The liabilities export and the residual owner equity complete the statement.

At the closing date, $750,000 of assets less $350,000 of liabilities leaves $400,000 of owner equity. Adding liabilities and equity returns exactly to assets. The same check works for the opening date: $345,000 plus $300,000 equals $645,000.

Reconcile the owner equity movement

The residual increased by $100,000, but the difference between two balance sheets does not explain why. First obtain net income from the final business income statement.

The detailed expense build belongs in the profit and loss statement. Here, the approved $160,000 net income is an input to the equity reconciliation.

The closing $400,000 matches the balance-sheet residual. The contribution is not customer revenue, and the draws are not payroll or another operating expense. IRS Publication 334 states that a sole proprietor cannot deduct their own salary or personal withdrawals as business expenses and describes a separate drawing account.

Reconcile contributions and draws to both the ledger and the underlying transactions. For this example, every contribution and draw is cash. If an owner contributes equipment instead, the asset and capital accounts need matching entries supported by the approved valuation and accounting treatment.

Change one input: a larger owner draw

Suppose Cedar makes an additional cash draw of $40,000 just before year-end. Hold every other transaction and balance unchanged. Total draws rise from $105,000 to $145,000.

The additional draw reduces cash and equity by $40,000. It leaves profit unchanged. The revised proof is $710,000 of assets equals $350,000 of liabilities plus $360,000 of owner equity.

This is why profit alone cannot answer how much cash remains in the business. The variation earns the same amount while holding less cash. Review the separate working capital calculation when deciding whether planned withdrawals leave enough funds for operating obligations.

The records that make the comparison reliable

Use a dated trial balance, reconciled bank balances, customer aging, inventory records, supplier balances, debt statements and the fixed-asset register. Tag owner transactions separately before generating the statement.

The bookkeeper prepares the schedules and tracks outstanding differences. The owner or designated finance lead reviews the reporting boundary, unusual capital transactions and withdrawals. For a period comparison, explain the largest account changes through flux analysis rather than treating every cash movement as a profit movement.

Keep evidence for each balance. A matching accounting equation cannot prove that receivables are collectible or equipment records are complete; it establishes that the recorded asset, liability and equity totals agree.

Where it goes wrong

• Recording contributions as sales. That overstates business revenue and obscures the capital movement.
• Charging owner draws to operating expenses. That understates operating profit and breaks the equity reconciliation unless corrected.
• Leaving out noncash business balances. Receivables, unpaid expenses and depreciation do not disappear because they are absent from a bank statement.
• Including borrowing twice. Split one loan between current and long-term portions without also adding the lender's full balance as another liability.
• Mixing reporting bases or dates. Opening accrual balances cannot be compared directly with closing cash-only records. Use consistent dates when preparing a projected balance sheet too.
