Define the period and gather source records
Identify the cleanup start date, the tax years involved, the accounting method, and every business bank, credit-card, loan, payment-processor, payroll, and merchant account used during the period.
Gather statements, prior returns, depreciation schedules, payroll reports, sales reports, loan documents, closing statements, and the prior clean closing balance sheet when available.
Reconcile cash and credit accounts first
Each bank and credit-card account should reconcile to its statement for every month. Missing transactions, duplicates, transfers recorded as income, and opening-balance adjustments should be investigated rather than forced into a generic category.
Payment processors may report gross sales, fees, refunds, and net deposits separately. Recording only the deposit can understate revenue and expenses.
Review income and expense classifications
Compare recorded revenue with invoices, processor reports, Forms 1099, and deposits. Review expenses for business purpose, correct category, personal items, duplicates, and transactions that belong to another entity or owner.
Large or unusual purchases may need asset treatment and depreciation rather than an immediate expense. Loan proceeds, owner contributions, and transfers are generally not revenue.
Make the balance sheet explainable
Verify accounts receivable, accounts payable, inventory, fixed assets, accumulated depreciation, loans, payroll liabilities, sales-tax liabilities, credit cards, and owner equity against supporting records.
Negative asset balances, unexplained suspense accounts, stale receivables, and loan balances that do not match lender statements are signals that more work is needed.
Separate owner activity and payroll
Classify owner contributions, draws, distributions, reimbursements, shareholder or partner loans, and personal expenses consistently with the entity's tax treatment.
Reconcile payroll expense and liabilities to payroll reports and employment-tax filings. Do not use owner draws or distributions as a substitute for payroll when wages are required.
Close the cleanup and prevent another backlog
Produce a final profit and loss, balance sheet, general ledger, reconciliation reports, open-item lists, and a written list of unresolved assumptions. Tie key balances to the tax return or provide clean workpapers for the preparer.
Then establish a monthly close: reconcile accounts, attach documentation, review uncategorized items, post payroll and loan activity, and inspect the balance sheet before the next month begins.
Key Takeaways
- Cleanup begins with complete source records and reconciled cash accounts.
- Transfers, loans, owner contributions, and net processor deposits should not be mistaken for revenue.
- The balance sheet is as important as the profit-and-loss statement.
- Owner activity, payroll, assets, and liabilities need entity-specific treatment.
- A documented monthly close prevents the same problems from returning.
