Year-End Bookkeeping: 14 Records to Gather

A year-end close is not a hunt for every PDF with a date on it. The job is to hand over a traceable set of records, balances that have been checked, and a short list of questions that still need an answer.

Decide what “year-end” means

Use the last day of the business’s tax year as the cutoff. Download statements through that date, keep later activity out of the folder, and label anything that crosses the line—such as a December invoice paid in January. The bookkeeper can decide how it should be recorded; your job is to make the timing visible.

Create one folder for the year. Inside it, use six plain subfolders: money in, money out, payroll and contractors, assets and debt, tax records, and open questions. A predictable handoff is more valuable than a clever filing system.

1. Prove the money in

Collect the records that show both the amount received and where it came from:

• sales invoices and the year-end accounts-receivable report;
• point-of-sale, marketplace, and payment-processor summaries;
• bank deposit records for cash or checks;
• refund, chargeback, and customer-credit reports; and
• Forms 1099-K or other income statements the business received.

Run one check: compare the annual sales-system total with income in the books. They may not match exactly—sales tax, refunds, transfers, and timing can create differences—but every difference should have a short explanation.

2. Prove the money out

Download every business bank and credit-card statement, then gather the invoices or receipts behind material purchases. A bank statement proves that money moved; it does not, by itself, show why the cost belonged to the business. The IRS makes the same distinction in Publication 583: supporting documents establish the business purpose behind entries in the books.

Flag three problem types instead of quietly categorizing them:

• a personal purchase paid from a business account;
• a business purchase paid personally; and
• a payment with no invoice, receipt, or written business purpose.

Give each flagged item a date, amount, payee, and one-line explanation. That turns a vague cleanup job into a finite review list.

3. Close payroll and contractor gaps

Put the final payroll register beside the quarterly payroll returns and year-end wage statements. The totals should agree or come with a reconciliation from the payroll provider. Include benefit, reimbursement, and owner-pay records that sit outside the normal payroll run.

For contractors, gather each payee’s W-9 and a report of total payments. The filing rule depends on the payment and recipient, so let the tax professional make the final call. When Form 1099-NEC is required for nonemployee compensation, the IRS says it is generally due to both the recipient and the IRS by January 31; weekend and legal-holiday rules can move the date. See the current IRS information-return guidance before filing.

4. Pull out what is not an ordinary expense

Large purchases, asset sales, new loans, principal payments, inventory changes, and money moving between the owner and the business often need separate treatment. Do not bury them in broad categories such as “equipment,” “transfer,” or “miscellaneous.”

For each asset purchase or sale, provide the date, description, price, financing documents, and disposal proceeds. For each loan, provide the opening balance, year-end balance, interest statement, and any modification or payoff paperwork.

5. Reconcile five balances

Before sending the folder, compare the books with the outside record for each of these:

1. Bank accounts: book balance to the final bank statement.
2. Credit cards: book liability to the final card statement.
3. Accounts receivable: customer balances to unpaid invoices.
4. Accounts payable: vendor balances to unpaid bills.
5. Loans: book liability to lender statements or amortization records.

A mismatch is not a reason to delay the handoff. Record the amount, identify the accounts involved, and put it on the open-questions list. An unexplained difference is the problem; a clearly labeled difference is work that can be assigned.

Hand over decisions, not a document dump

Add one spreadsheet or note called OPEN ITEMS. Each row needs only five fields: date, amount, account, what is unclear, and who can answer. Keep missing documents on the same list.

The finished package should let a bookkeeper answer three questions quickly:

• Where did this number come from?
• What has already been reconciled?
• What still needs a decision?

If those answers are visible, the handoff is ready even if a few items remain unresolved.

Keep records by rule, not habit

Do not apply one retention period to every file. The IRS says records supporting income, deductions, and credits generally need to be kept until the applicable period of limitations expires. Employment-tax records generally have a four-year minimum, while asset records may need to stay with the business until after the asset is disposed of and the related period expires. Start with the IRS guidance on how long to keep records, then confirm the period with the business’s tax professional.

Final 20-minute check

• Every account has a final statement.
• Every statement balance is matched or listed as an open item.
• Income can be traced from the sales system to deposits and the books.
• Material expenses have both proof of payment and a business-purpose document.
• Payroll, contractor, asset, debt, and owner transactions are separated from ordinary expenses.

That is the standard: not a perfect folder, but a close that another person can follow without reconstructing the year from scratch.
