8 Tips to Get Your Books Ready for Year-End

As the calendar winds down, so does your window to optimize your financial records and minimize your tax liability. Year-end bookkeeping isn’t just about closing the books—it’s a strategic opportunity to clean up your finances, uncover savings, and prepare for a smoother tax season. Whether you're a small business owner, freelancer, or entrepreneur, these eight tips will help you get your books in order and potentially lower your tax bill.

1. Reconcile All Accounts

Start by reconciling your bank accounts, credit cards, and loan statements. This ensures that your accounting software matches your actual financial activity.

• Match every transaction to a corresponding entry.

• Investigate discrepancies and correct errors.

• Reconcile regularly to avoid a last-minute scramble.

Why it matters: Unreconciled accounts can lead to inaccurate financial statements and missed deductions.

2. Categorize Expenses Accurately

Review all your expenses and ensure they’re properly categorized. Misclassified expenses can result in missed tax deductions or even IRS scrutiny.

• Use consistent naming conventions.

• Separate personal and business expenses.

• Flag any unusual or one-time costs for your accountant.

Pro tip: Software like QuickBooks or Xero can automate categorization, but manual review is still essential.

3. Review Income and Invoices

Make sure all income is recorded and outstanding invoices are followed up.

• Send reminders for unpaid invoices.

• Write off bad debts if necessary (consult your accountant first).

• Record any income received outside your usual channels.

Why it matters: Accurate income reporting is crucial for tax compliance and cash flow forecasting.

4. Organize Receipts and Documentation

Receipts are your proof of business expenses. Without them, you risk losing deductions.

• Digitize paper receipts using apps like Expensify or Hubdoc.

• Store them in organized folders by category and date.

• Keep documentation for major purchases, travel, and meals.

IRS guidelines require you to retain receipts for at least three years—don’t wait until an audit to get organized.

5. Maximize Deductions Before December 31

Now’s the time to make strategic purchases or investments that qualify as deductible expenses.

• Buy office supplies, software, or equipment.

• Prepay for services or subscriptions.

• Contribute to retirement plans (like SEP IRAs or solo 401(k)s).

Consult your tax advisor to ensure these moves align with your overall financial strategy.

6. Review Depreciation and Asset Records

If you’ve purchased equipment, vehicles, or property, make sure they’re properly recorded and depreciated.

• Update your fixed asset register.

• Apply correct depreciation methods (straight-line, declining balance, etc.).

• Consider Section 179 deductions for eligible assets.

Why it matters: Depreciation can significantly reduce your taxable income, but only if recorded correctly.

7. Run Financial Reports and Analyze Trends

Generate key reports to assess your business’s financial health:

• Profit & Loss Statement

• Balance Sheet

• Cash Flow Statement

Look for trends, anomalies, or areas of concern. Are expenses rising faster than revenue? Is your debt ratio increasing? These insights can guide year-end decisions and next year’s strategy.

8. Consult Your Accountant or Tax Advisor

Even if you manage your own books, a year-end review with a professional is invaluable.

• Discuss potential tax-saving strategies.

• Review estimated tax payments and liabilities.

• Plan for upcoming changes in tax law or business structure.

A good accountant can help you avoid costly mistakes and uncover opportunities you might miss on your own.
