With 2025 coming to a close, a thorough year-end accounting review is essential for any business to ensure financial health and maximize tax savings. Many businesses fail because of cash flow problems, often rooted in disorganized books.

That’s where a structured year-end accounting checklist comes in. It brings clarity, highlights deductions you might miss, and ensures every account is reconciled with precision. Most importantly, it lays a solid foundation for the year ahead. Done right, it prepares you for due diligence, gives balance sheets the accuracy they need, and turns financial statements into tools that inspire confidence and support growth.

Why Proper Year-End Accounting Matters for US Firms?

Year-end accounting is the foundation for compliance, tax savings, and future planning. For US firms, it safeguards against penalties, strengthens credibility, and provides clarity for growth decisions. Here’s a glimpse of why it matters:

• Keeps firms aligned with IRS filing requirements, prevents penalties, and ensures correct payment of taxes and credit claims.
• Highlights real inflows or outflows, helps manage debt, and reduces the risk of failure from cash flow gaps.
• Captures all allowable deductions and credits, lowering tax liability and freeing resources for reinvestment.
• Provides clean, reliable statements that improve financing, build trust, and attract investors or partners.
• Ensures books match bank and credit records, preventing fraud, errors, and compliance risks.

Year-End Accounting Checklist for 2025

Year-end accounting involves reconciling every transaction, reviewing payables and receivables, chasing overdue invoices, leveraging accrued expenses for tax savings, recognising bad debts, calculating depreciation, and ensuring that personal or loan-related business expenses are properly recorded.

It also means valuing inventory, reconciling payroll and sales tax, making provision for 401K, preparing close schedules, compiling and backing up all essential records; each step in the year-end close keeps your business financially accurate and ready for 2026. Here’s what should be on your year-end accounting and bookkeeping checklist:

Hire A Dedicated Accountant Who:

Prepares Accurate IRS Tax Teturns

Quick Start within 48 Hours

• • All The Transactions Have Been Recorded

As you begin, make sure every financial transaction up to 31 December 2025 is posted into your books. This includes bank and credit card feeds, petty cash expenses, vendor bills, payroll entries, merchant fees, and recurring expenses like rent, utilities, bad debt, discount given or received.

Moreover, clear any balances sitting in suspense accounts such as uncategorized expenses, opening balance equity or undeposited funds. By the end of the year accounting review, your trial balance should reflect all actual transactions, giving you a clean foundation for adjustments and reporting.

• • Post Year-end Adjustment Entries

Make all the necessary adjustments to reflect the correct financial position. These may include accruals for expenses like utilities or legal fees, and revenue such as accrued revenue, deferrals for prepaid expenses and deferred revenue, revenue cut-off adjustments, and reclassification between capital, operating, and recording of home expenses.

If four businesses deal with multiple currencies, revalue receivables, payables, and cash balances at the year-end exchange rate. Create revising entries dated 1 January 2026 for items that should not be carried forward into the new period.

• • Review Accounts Payable and Receivable and Reconcile with Vendors and Customers

Run an aging report for both accounts payable and accounts receivable. Cross-check balances against vendor and customer statements to confirm accuracy. Identify unapplied credits, duplicate bills, or payments that haven’t been matched. For significant balances, request confirmations directly from vendors and customers.

In case you missed recording some vendor invoices, recording of same will not only improve accuracy but also helps minimize your tax bills. Reconciliation ensures your liabilities and receivables reflect the true amounts owed, eliminating disputes and errors before closing the books.

• • Collect Past-due Invoices

Cash flow gaps often start with unpaid customer invoices. Before year-end, review all overdue accounts receivable, segmenting them by how long they have been outstanding (30, 60, 90+ days). Send follow-up reminders, negotiate payment plans if needed, and escalate collections where appropriate.

Also, if any discount is to be given or bad debt recognized, it can help reduce the overall tax liability. Past-due collections not only strengthen cash flow but also reduce the risk of writing off receivables later. This step is critical for presenting accurate revenue figures and for improving working capital before entering the next financial year.

• • Leverage Accrued Expenses for Tax Benefits

Record expenses incurred but not yet paid, such as utilities, consultancy charges, professional, commission, or management fees. Accruing these ensures expenses are recognised in the correct year, lowering taxable income. This year-end adjustment helps reflect true financial performance and may reduce tax liabilities by aligning expenses with the related income.

• • Creation of Provision for Bad Debt Expense

Evaluate accounts receivable to determine which balances are unlikely to be collected. Based on your company’s bad debt policy or historical experience, create a provision for doubtful accounts. This ensures your financial statements do not overstate revenue or receivables and helps you secure a tax deduction for the expected loss. At year-end accounting review, writing down uncollectible receivables keeps your balance sheet realistic.

• • Calculate Depreciation Expense

Review fixed assets such as machinery, vehicles, or equipment and record depreciation for the year. Year-end accounting calculation ensures asset values and expenses are up to date, which directly impacts profits and tax deductions.

Also, review IRS provisions to determine if MACRS (Modified Accelerated Cost Recovery System), Section 179 Deduction, or Bonus Depreciation can be claimed. For instance, if you purchased a delivery van for $30,000 with a five-year useful life, you’ll record $6,000 as depreciation expense for 2025. This reduces taxable income while reflecting wear and tear on assets.

• • Business Expense Paid Via Personal Account

Check if any business-related payments were made from personal funds. Record them properly in the company’s books to avoid underreporting expenses. This ensures your accounts show the true cost of operations, and at tax time, you claim all allowable deductions instead of missing legitimate write-offs.

• • Review and Reconcile Loan Balances, Bank Balance, and Credit Cards

Match your year-end loan, bank accounts, and credit card statements with the balances recorded in your books. Confirm principal and interest portions are correctly separated for loan payments, and ensure the interest portion and any bank or credit charges are duly recorded in the profit and loss account.

Also, verify that bank reconciliations include all uncleared deposits and cheques. This ensures liabilities, cash, and expenses are accurate, giving you a clear view of financial obligations heading into 2026.

• • Valuation of an Inventory

Conduct a physical stock count and compare it with your recorded inventory levels. Adjust discrepancies and ensure valuation aligns with accounting standards. Ensure valuation follows your accounting policy (FIFO, weighted average, etc.) and write down slow-moving or obsolete stock. Accurate inventory reporting ensures the correct calculation of cost of goods sold (COGS) and prevents overstating profits.

• • Reconcile Payroll Records

Cross-check payroll reports with your general ledger to confirm wages, benefits, and taxes have been recorded correctly. Accrue any unpaid wages, bonuses, or leave balances as of 31 December. This reconciliation ensures employees’ earnings are reported accurately, tax filings are correct, and there are no hidden payroll liabilities going into the new year.

• • Carry Out Intercompany Adjustments

If your business has multiple entities, reconcile all intercompany balances and in case inter-company balances are not matching, pass the necessary adjustment entries. Revalue intercompany balances in foreign currency at year-end exchange rates.

Documents transfer pricing policies and ensure adjustments comply with statutory regulations. These steps maintain consistency across group entities and ensure accurate consolidated reporting.

• • Reconcile Sales Tax Payable and Sales as Per Sales Tax Return

Verify that the sales tax liability in your books matches the amount filed in sales tax returns. Cross-check taxable sales figures with reported revenue and ensure exempt or export sales are properly documented. Also, check for use tax obligations on purchases where sales tax wasn’t collected. Accurate reconciliation prevents tax penalties and compliance issues.

• • Ensure Last Year Adjustments Entries Are Posted on 31 December 2024

Check that all post-closing adjustments from 2024 were recorded with a date of 31 December 2024, not carried into 2025. If any corrections are required, adjust retained earnings appropriately and document the rationale. Ensuring prior-year adjustments are properly dated avoids misstatements in current-year results.

• • Prepare Financial Documents and Do Comparative Analysis

Compile your core financial statements, income statement, balance sheet, and cash flow statement for 2025. Alongside these, prepare comparative figures for 2024 and highlight significant variances with explanations. This analysis provides insights into performance trends, supports management decisions, and strengthens reporting for auditors, lenders, or investors.

• • Prepare a Financial Close Schedule

Compile your core financial statements, income statement, balance sheet, and cash flow statement for 2025. Alongside these, prepare comparative figures for 2024 and highlight significant variances with explanations.

This analysis provides insights into performance trends, supports management decisions, and strengthens reporting for auditors, lenders, or investors. However, if you find any missing expenses, do record the same that which will lower your taxable profit.

• • Tax Adjustment Entries

Record tax adjustment entries by posting year-end provisions for income tax payable, updating deferred tax assets/liabilities, and adjusting for prepaid or outstanding tax balances. Reconcile entries with IRS filings to match taxable income with accounting records, ensuring compliance and avoiding penalties for the 2025 year-end close.

• • Do Other Adjustments

Post another adjustment entries for year-end, including charitable donations, accrued retirement plan contributions, and unpaid bonuses or commissions. Ensure these are recorded as liabilities or expenses in 2025 financials, aligning with payroll and HR records. Accurate adjustments secure compliance, reflect true obligations, and support tax benefits where applicable.

• • Compile All Necessary Documents

Gather supporting records like receipts, invoices, bank and credit card statements, loan records, and contracts to back financial data. These documents back up your financial reports and tax filings. At year-end accounting review, complete documentation reduces audit risks, supports transparency, and provides easy access if the tax authority or auditors request evidence for reported transactions.

• Create Backups of Important Information

Secure digital and physical copies of financial data, including ledgers, tax filings, and reports. Use encrypted drives or cloud storage for protection. Backups safeguard against data loss due to system failures or cyber risks, ensuring you can access critical records whenever needed, especially during audits or tax reviews.
