Year-end bookkeeping is not tax preparation. It is the work of making your own record complete, consistent, and understandable before anyone uses it to prepare a return or make a business decision.
The fastest year-end close starts with 12 completed months. If the monthly work was skipped, begin with January and move in order. That makes duplicates and gaps easier to spot than working from one giant annual bank export.
1. Confirm all 12 months are complete
Each month should include money in, money out, off-bank activity, expenses, and helpers paid. Compare each month with its bank and card statements and list anything that still needs an explanation.
2. Confirm all income sources
Add cash, checks, card processors, bank transfers, Venmo, Zelle, Cash App, and any other payment source. A tax form from a processor is not a substitute for your own complete sales records, and transfers or loans should not be mistaken for sales.
3. Review expenses and categories
Scan annual totals for categories that look unusually high, low, or empty. Check that recurring vendors stayed in the same category and clear the miscellaneous or unknown bucket before handing over the books.
4. Separate equipment and large purchases
Give your tax professional a list of equipment, vehicles, or other longer-lived purchases with dates and costs. Do not decide depreciation treatment from a generic article; provide the facts and ask how each item should be handled.
5. Separate loans and owner activity
Loan proceeds are not ordinary sales, and loan principal is not an ordinary expense. Owner contributions, draws, and distributions also need to stay separate from operating income and expenses.
6. Review helpers and contractors
Total each person separately and gather the records you have, including W-9 information where applicable. Ask a qualified professional to confirm classification, current thresholds, forms, and deadlines.
7. Gather records outside the bank feed
- Business mileage records and vehicle-use details.
- Home office measurements and eligible cost records, if applicable.
- Inventory counts for businesses that carry inventory.
- Receipts and business-purpose notes for travel and meals.
- Loan statements, equipment purchase documents, and prior depreciation schedules.
8. Build the year-end handoff
Prepare annual money-in, money-out, and net totals; a month-by-month breakdown; expenses by category; helpers paid; itemized entries; and a short list of unresolved questions. Keep source documents available rather than sending an unexplained folder.

The workbook includes a 10-item year-end checklist, a 12-month summary with formulas, a handoff-notes sheet, and a plain-language disclaimer. It contains no client names or fabricated results.
The easier approach for next year
Close one month at a time. The LedgerFast Year Book keeps the 12 months together and produces the PDF or Excel packet without rebuilding the year from scratch. One tax year costs $99.
