When business gets busy, receipts can pile up, transactions may stay uncategorized, and account balances can go unchecked. Taking time before December 31 to review your books can make year-end less stressful and give your tax preparer clearer, more complete records.

This practical small business bookkeeping checklist focuses on the close tasks to complete before the year ends. Some steps, such as bank reconciliation, can be done now. Others, like a final inventory count, may need to wait until December 31 or the last business day of your year.

Start With a Simple Close Plan

Set aside time in November and December to review records in manageable steps. Make a list of accounts, documents, and questions that need attention. If you use accounting software, save a backup or export before making year-end changes.

Keep your receipts, statements, and reports together in a secure digital folder. The IRS explains in Publication 583 that business records should support the income and expenses reported on your tax return. A clear file system helps you find that support when you need it.

Reconcile Every Business Account

Reconciliation means comparing your bookkeeping records with the statements from your bank, credit card company, or other financial provider. It helps catch missing or duplicated transactions before they carry into the next year.

Before December 31, review each business:

• Checking and savings account
• Credit card
• Loan or line of credit
• Payment processor, such as Stripe, Square, or PayPal
• Payroll or sales-tax account, if applicable

Match the transactions in your books to statements through the latest available date, then complete the final reconciliation when December statements arrive. Look for bank fees, interest, transfers, outstanding checks, deposits in transit, and charges that appear on a card statement after the purchase date.

If a balance does not match, investigate it rather than adding a quick adjustment to make the numbers agree. Save the statements and reconciliation reports with your year-end records.

Find Missing Receipts and Unclear Transactions

Review your receipt folders, email, expense apps, and paper files for missing support. Pay particular attention to business purchases made with a personal card, online subscriptions, travel, meals, mileage, and equipment.

Next, look through your accounting system for transactions marked “uncategorized,” “ask my accountant,” or “suspense.” Identify each item using a receipt, invoice, vendor name, or payment detail, then assign it to the appropriate category.

Some transactions need an extra review. A deposit might be a loan or owner contribution rather than sales income. A payment might include both loan principal and interest. Personal purchases and business expenses should not be mixed into the same category. If you are unsure how to treat an item, note the question for your bookkeeper or tax preparer instead of guessing.

Review Income, Bills, and Customer Balances

Compare your sales records with invoices, deposits, point-of-sale reports, and payment processor summaries. Net deposits may be lower than gross sales because processors deduct fees, so check that your books account for both the sales and the fees.

Review unpaid customer invoices and vendor bills. Make a note of balances that need follow-up or clarification, including credit notes, customer deposits, and bills for work completed before year-end. The right treatment can depend on your accounting method and circumstances, so ask your tax professional about unusual timing questions.

This review can also help you spot a missing invoice or payment before it becomes harder to track down.

Check Payroll and Contractor Records

If you have employees, compare your payroll reports with your bookkeeping records. Review gross wages, payroll tax payments, benefits, reimbursements, and payroll account balances. Confirm that your payroll provider’s year-end totals align with your records and flag any differences for review.

For contractors and other vendors, run a payment report for the year. Check that names, mailing addresses, payment totals, and taxpayer information are complete. Collect or confirm Form W-9 information where needed, and distinguish payments made directly from those processed through a card or third-party payment network.

This preparation supports accurate information-return reporting, including 1099 forms when required. Reporting rules and thresholds can change, and requirements depend on the type and method of payment. Check the current IRS information-return guidance and confirm the filing rules that apply to your business. Do not wait until January to discover that a vendor’s information is missing.

Verify Inventory Before the Year Ends

If you sell or make products, plan a physical inventory count for December 31 or the date required by your accounting process. Record the items, quantities, and any damaged or obsolete goods. Keep notes about who performed the count and when it took place.

Then compare the count with your inventory records. Investigate differences such as unrecorded sales, returns, receiving errors, or goods in transit. Keep supporting purchase records and count sheets together. Inventory can affect the cost of goods sold shown in your financial records, so ask your tax preparer how to handle uncertain or unusual items.

Review Equipment, Loans, and Owner Activity

Check the year’s equipment and other major purchases. Note what was bought or sold, the purchase date, and when an item was placed in service. Keep invoices and records of business use. Your tax preparer can review how purchases should be treated for tax purposes.

Reconcile loan balances with lender statements and separate principal from interest in your books. Also review owner contributions, draws, distributions, and reimbursements. These should be recorded clearly rather than treated as ordinary sales or expenses.

If you have a corporation, partnership, or multiple owners, bring questions about owner payments or changes in ownership to your tax professional.

Run and Review Year-End Reports

Once the books are updated and reviewed, run your year-end reports. Common reports include:

• Profit and loss statement
• Balance sheet
• Cash flow statement
• General ledger
• Accounts receivable and payable aging
• Inventory report, if applicable
• Payroll summary

Look for unusual changes, negative balances, unexplained expenses, or large differences from last year. Confirm that important accounts, such as loans, payroll liabilities, and sales tax payable, make sense. If something is unclear, add a note and gather the related statement or receipt.

These reports give you and your tax preparer a clearer picture of the business. For general guidance on the records businesses may need to keep, see the IRS recordkeeping resource.

Prepare a Tax-Ready Handoff

Before sharing records with your tax preparer, collect:

• Final financial reports and general ledger
• Prior-year tax return
• Bank, credit card, and loan statements
• Receipts, invoices, and purchase records
• Payroll reports and tax filings
• Contractor payment information and W-9s
• Inventory count and valuation records, if applicable
• Equipment and asset information
• Estimated tax payment details
• Any IRS or state notices

A complete package can reduce back-and-forth questions and help your preparer get to work sooner. Clear, organized records may also reduce the need for separate cleanup work before tax preparation begins. The time and cost of professional services depend on the condition of your books and the needs of your business.

A Manageable Close Starts Now

You do not need to complete every year-end task in one sitting. Start with reconciliations and missing documents, then review payroll and contractors. Schedule inventory and final statements for the appropriate date, and finish by reviewing reports and preparing your tax handoff.
