The end of the year is an important checkpoint for your business bookkeeping.

Before financial reports are provided to your tax professional, the activity behind those reports should be reviewed for accuracy and completeness.

A year-end bookkeeping review helps identify unreconciled accounts, missing transactions, incorrect balances, contractor reporting questions, and other issues that may affect your financial reports.

This process does not determine which deductions or credits you can claim. That responsibility belongs to your qualified tax professional. Our role is to organize and review the financial records your tax professional will use.

Completing this work before the filing deadline gives everyone more time to investigate questions, gather documentation, and make appropriate corrections.

Quick Takeaways

• Year-end bookkeeping should begin only after earlier periods have been completed and reconciled.
• Bank, credit card, loan, and payment-processing balances should be reviewed against official statements.
• Financial reports should be checked for unusual or unexplained balances.
• Contractor and payroll records require review before applicable reporting deadlines.
• Asset purchases, owner transactions, loans, and liabilities should be recorded appropriately.
• Your bookkeeper organizes the financial records; your tax professional determines tax treatment.
• A year-end review also provides a stronger starting point for the next year.

What Is a Year-End Bookkeeping Review?

A year-end bookkeeping review is a structured examination of the business’s financial records after the final activity for the year has been recorded.

The review helps confirm that transactions are complete, accounts are reconciled, and the reports reasonably reflect the activity recorded in QuickBooks.

Depending on the business, the review may include:

• Completing unfinished bookkeeping periods
• Reconciling bank and credit card accounts
• Reviewing loans and other liabilities
• Examining the chart of accounts
• Reviewing income and expense categories
• Checking accounts receivable and accounts payable
• Reviewing payroll and contractor activity
• Identifying business assets purchased or sold
• Reviewing owner contributions, draws, and distributions
• Investigating unusual financial report balances
• Organizing reports and supporting documents for the tax professional

A year-end review is not a replacement for monthly bookkeeping. It works best when the accounts have already been maintained throughout the year.

Reconcile All Financial Accounts

Every applicable bank and credit card account should be reconciled through the final statement ending date for the year.

Reconciliation compares the transactions recorded in QuickBooks with the official statement for the same period. It can identify:

• Missing transactions
• Duplicate activity
• Incorrect transaction dates
• Bank fees or interest that were never recorded
• Payments entered for the wrong amount
• Activity recorded in the wrong account
• Previously reconciled transactions that were changed
• Incorrect beginning or ending balances

Savings accounts, payment processors, and loan accounts may also require review. If a problem begins in an earlier period, that period should be corrected before later periods are completed.

A bank-feed balance that matches the bank’s website does not prove that the account has been reconciled. The individual transactions and statement balance still require verification.

Review Income for Completeness and Duplication

Year-end income should be reviewed across all the systems the business uses to receive money.

These may include:

• Customer invoices
• Sales receipts
• QuickBooks Payments
• Stripe
• PayPal
• Square
• Online stores
• Other merchant processors
• Bank deposits

A common bookkeeping problem occurs when a customer payment is already recorded through an invoice or sales receipt but the corresponding bank deposit is added as new income. This can overstate revenue.

Deposits should be matched to the underlying sales activity whenever possible. Processing fees, refunds, chargebacks, transfers, and timing differences should also be recorded appropriately.

Income records may not match payment-processor forms dollar for dollar because the systems can use different reporting rules. Differences should be investigated and explained rather than forced to match.

Examine Expense Categories

Expense categories should provide a clear and consistent picture of how the business spent its money.

During the year-end review, we look for issues such as:

• Large balances in miscellaneous or uncategorized expenses
• Personal transactions recorded as business expenses
• Transfers categorized as expenses
• Loan principal recorded entirely as an expense
• Equipment purchases included in ordinary supplies
• Contractor payments recorded inconsistently
• Duplicate expenses
• Reimbursements that were not recorded
• Expenses recorded in the wrong period
• Cost of goods sold included in operating expenses

Correct bookkeeping classification does not automatically make an expense deductible. Your tax professional determines whether the expense qualifies and how it should be reported on the tax return.

Review the Balance Sheet Carefully

The Balance Sheet often reveals problems that are not visible on the Profit and Loss report.

It contains the balances for the business’s assets, liabilities, and equity at a specific date. These balances frequently carry forward from one year to the next, so unexplained amounts should not be ignored.

Bank and Credit Card Accounts

These balances should agree with the completed reconciliations for the year.

Accounts Receivable

Outstanding customer invoices should be reviewed for payments that were never applied, duplicate invoices, credits, or balances that may no longer be collectible.

Accounts Payable

Unpaid vendor bills should be reviewed for duplicates, missing payments, credits, and transactions that may no longer be outstanding.

Loans and Other Liabilities

Loan balances should be compared with year-end lender statements when available. Principal, interest, and additional fees should not all be recorded as the same type of expense.

Business Assets

Equipment, vehicles, furniture, and other significant purchases should be identified and supported with available purchase documentation.

Your tax professional determines depreciation and other tax treatment. The bookkeeping should clearly show what was purchased, when it was purchased, how much it cost, and how it was paid for.

Owner Equity

Owner contributions, draws, distributions, and other equity activity should be reviewed for consistency with the business structure.

Personal expenses should not remain mixed into ordinary business operating expenses merely because they were paid from the business account.

Review Payroll and Contractor Activity

Payroll and contractor records should be reviewed before applicable year-end reporting deadlines.

The review may include:

• Employee names and addresses
• Payroll totals
• Payroll tax liabilities
• Reimbursements and benefits
• Payments processed outside the payroll system
• Contractor names and payment totals
• Forms W-9
• Payments made with personal funds
• Vendor entity information
• Contractor payments recorded in multiple accounts

Businesses that pay independent contractors may be required to file Form 1099-NEC or another information return, depending on the payment, payee, amount, and current reporting requirements.

The IRS provides current guidance on reporting payments to independent contractors.

Reporting thresholds and requirements can change. Your tax professional should confirm which forms your business must file.

Identify Missing Supporting Documents

QuickBooks contains the accounting records, but additional documentation may be needed to support the transactions recorded there.

Depending on the business, year-end documents may include:

• Bank and credit card statements
• Loan statements
• Equipment purchase agreements
• Vehicle purchase or financing documents
• Payroll reports
• Contractor Forms W-9
• Merchant-processor reports
• Sales tax reports
• Inventory records
• Receipts for significant purchases
• Prior-year financial reports
• Documentation for assets that were sold or disposed of

The IRS explains that good records help businesses prepare financial statements, track expenses, prepare tax returns, and support the amounts reported on those returns.

Additional information is available in the IRS small-business recordkeeping guidance.

We organize the available bookkeeping documentation, while your tax professional determines whether additional substantiation is required.

What Financial Reports Should Be Reviewed?

Once the bookkeeping is complete, several reports can help identify remaining questions.

Profit and Loss

The Profit and Loss summarizes income and expenses over the reporting period.

Review it for:

• Significant changes from the prior year
• Negative income or expense balances
• Unusually high or low categories
• Duplicate revenue
• Uncategorized activity
• Personal transactions
• Categories that do not match the nature of the business

Balance Sheet

The Balance Sheet reports assets, liabilities, and equity as of the report date.

Review it for:

• Incorrect bank or credit card balances
• Negative asset or liability balances that do not make sense
• Old accounts receivable or accounts payable
• Loans that do not agree with lender records
• Undeposited funds that have not cleared
• Uncategorized assets or liabilities
• Old opening-balance amounts
• Equity balances requiring explanation

Accounts Receivable Aging

This report shows outstanding customer invoices and how long they have remained unpaid.

Accounts Payable Aging

This report shows unpaid vendor bills and their aging.

General Ledger

The General Ledger provides the detailed activity recorded in each account and can help answer questions raised by the summary reports.

How a Year-End Review Supports Tax Preparation

A year-end bookkeeping review does not create tax savings or guarantee a lower tax liability. It helps ensure that the tax professional receives more complete and organized financial information.

Reliable records can help the tax professional:

• Understand the business’s income and expenses
• Identify questions that need answers
• Review potential deductions and credits
• Evaluate asset purchases
• Review owner and payroll activity
• Prepare required returns and forms
• Request missing documentation before deadlines

The IRS maintains current information about business credits and deductions, but eligibility depends on the business’s specific facts and current law.

Questions about deductions, credits, entity elections, tax strategy, or the treatment of a transaction should be directed to a qualified tax professional.

Use the Review to Prepare for the Next Year

A year-end review is not only about tax preparation. It also creates a cleaner beginning for the next bookkeeping year.

The review may reveal opportunities to improve:

• Receipt-collection procedures
• Customer invoicing
• Vendor bill tracking
• Contractor documentation
• Bank rules
• Payment-processor workflows
• Owner reimbursement procedures
• Loan-payment recording
• Monthly reconciliation schedules
• Communication between the owner, bookkeeper, and tax professional

If the same bookkeeping issue occurred repeatedly during the year, the workflow causing it should be addressed. Otherwise, the same problem may continue into the next year.

From Tiffany’s Desk

A year-end review should never be about changing the books simply to produce a more favorable result.

It is about making sure the financial records tell the most accurate story possible based on the information available.

When we review a client’s books, we look beyond the total at the bottom of the Profit and Loss. We review the accounts behind that number, investigate balances that do not make sense, and identify transactions that require clarification.

Some questions belong with us as the bookkeeper. Others belong with the tax professional. Knowing that difference protects the client and creates a smoother process for everyone involved.

Our goal is to provide organized, reliable bookkeeping that gives your tax professional a strong foundation for completing their work.

Frequently Asked Questions

When should a year-end bookkeeping review begin?

Monthly bookkeeping should be maintained throughout the year. The final year-end review can begin once the last statements and financial activity for the year are available.

Is a year-end review the same as preparing a tax return?

No. A year-end bookkeeping review organizes and verifies the financial records. A qualified tax professional prepares the return and provides tax advice.

Can a year-end bookkeeping review identify possible deductions?

It can identify and organize expenses that may require review. Your tax professional determines whether an expense is deductible and how it should be reported.

What if my bookkeeping is several months behind?

Catch-up bookkeeping should be completed first. Each period should be addressed chronologically so earlier errors do not carry into the final year-end reports.

Do all businesses need to issue Forms 1099?

No. Requirements depend on the type of payment, payee, amount, payment method, and current rules. Contractor records should be reviewed, and a qualified professional should confirm the business’s filing requirements.

Can I complete the year-end review without reconciling every month?

Accounts should generally be reconciled in chronological order through the end of the year. Skipping periods can allow missing or duplicated activity to remain in the books.

How does an annual review help with business planning?

It provides more reliable information about income, expenses, cash flow, assets, liabilities, and outstanding balances. That information can help the owner create budgets and evaluate priorities for the next year.
