Prerequisites
First practice the four closing steps with a profit. Read debit and credit balances and keep owner drawings separate from expenses. Use only these fictional records.
Use the same four steps as for a profitable period: revenue to Income Summary, expenses to Income Summary, summary to Owner Capital, drawings to Owner Capital. If expenses exceed revenue, Income Summary has a debit balance: credit Income Summary and debit Owner Capital to close the loss. Drawings also reduces capital, but is not an expense. A post-closing trial balance includes nonzero permanent balances, not the cleared temporary ones.
Worked example
Separate example: credit Revenue 20 and debit Expense 35 leave Income Summary with debit 15 after those accounts close. Debit Owner Capital 15 / credit Income Summary 15 closes the loss. Debit Owner Capital 4 / credit Drawings 4 closes a recorded withdrawal. Starting capital credit 100 becomes credit 81. Neither closing entry changes Cash.
Paper Flag Workshop / End of October
Use fictional dollars and these adjusted balances before closing: Cash debit 110; Equipment debit 60; Accounts Payable credit 30; Owner Capital credit 180; Service Revenue credit 40; Rent Expense debit 45; Supplies Expense debit 20; Drawings debit 15. Income Summary starts at zero. All adjustments and financial statements are complete. There are no other accounts or new transactions. Use the four-step Income Summary method. Drawings was already recorded; it is not an additional cash payment.
