Q4 could be the busiest time of the year for businesses. Between closing out the fiscal year-end, managing cash flow, preparing for tax obligations, reviewing results, and planning for the new year, accounting teams will have a lot to do on their hands.
That is why pre-October is the best time to get one’s accounting in order.
Timely accounting review during Q4 can help businesses spot financial errors, get better cash flow visibility, prepare for taxes, etc.
Below are 10 things that businesses should do before October to begin Q4 with clean books and clarity.
Reconcile All Bank and Credit Card Accounts
To kick off Q4 on the right financial foot, ensure that all business bank accounts, credit cards, and other financial accounts are reconciled thoroughly.
Examine your accounts against the relevant bank statements and check the following:
- Gaps or repeated transaction entries
- Deposits and/or payments missing in the accounting records
- Bank charges and interest payments
- Transactions and cheques awaiting clearance
- Any discrepancies that cannot be explained
Doing regular bank reconciliations ensures that the cash position and balance sheet record of the business reflects the actual financial activity of the business.
In case the discrepancies are not resolved, they can result in issues when preparing tax returns and for financial accounting.
Review Accounts Receivable and Outstanding Invoices
Unpaid invoices can impose undue strain on various aspects of business cash flow.
Revisit the accounts receivable (AR) aging report and ascertain overdue amounts that need attention before the end of the third quarter. Separate current outstanding invoices from those that are overdue and take note of which customers must be contacted.
Consider the following steps in this process:
- Send reminders for overdue invoices
- Go over payment terms with customers
- Follow up with customers with overdue amounts
- Know which accounts are uncollectible
- Change cash flow estimates accordingly
Having a seamless accounts receivable process will lead to improvements in working capital and offer a better overview of cash available for the management to use.
Clean Up Accounts Payable and Unpaid Bills
Accounts payable must receive similar focus to that of accounts receivable.
Examine the outstanding payables to ensure that all expenses incurred during the year have been properly recorded. Look for duplicate invoices as well as for any open bills, wrong balances with vendors, and errors in posting expenses.
Conducting a proper accounts payable review helps businesses to:
- Prevent late payment charges
- Establish good relationships with vendors
- Calculate liabilities accurately
- Plan cash flow more effectively
- Avoid duplicate payments
Cleaning up accounts payable before Q4 also facilitates a smooth year-end closure of accounts.
Review the Year-to-Date Profit & Loss Statement
Your year-to-date profit and loss statement (P&L) serves as more than a historical document; it provides information about your current financial situation as well as your future prospects.
Look at the revenues, the gross profits, the operating expenses and the net income as compared to a budget or historical periods.
Here are some issues to keep an eye on:
- Unanticipated increases in expenses
- Decreased revenues
- Fluctuations in gross margin ratios
- Anomalous transactions
- Big discrepancies with the budget
This type of assessment allows business owners to make timely, operational decisions during Q4 rather than waiting until the end of the year.
Update Cash Flow and Q4 Cash Projections
Profitable doesn't imply solid cash flow.
As one gets into the last quarter of the year, having a revitalized cash flow projection is in order taking into account revenue forecasts, customer collections, payroll, bills, taxes, debts and large expenses.
Having crafted a cash flow forecast, an entrepreneur should calculate different scenarios:
- The cash flow itself
- The conservative approach regarding revenue projections
- The greater-than-expected expenses
- Delays in payments made by clients
Having an accurate cash projection helps companies find out whether they have enough liquidity to run their businesses, invest in development or cope with surprises along the way.
Check Payroll, Benefits, and Payroll Tax Records
There is another important part of reviewing before the conclusion of the fourth quarter.
Check employee details, salary, benefits, deductions from payroll, and qualifying tax records for payroll.
It is also important for a business to check if their payroll taxes and providing documentation are covered according to the regulations set out by the federal government.
The IRS oversees the official calendar for tax filings and payroll tax deposits.
If the business operates in many states, it would be critical for them to check for payroll and tax compliance in states where they operate, as requirements may differ from one state to another.
If the business needs help with payroll, they can look into outsourcing payroll for their business with Xconcile.
Review Tax Payments, Estimated Taxes, and Compliance Deadlines
The fourth quarter is an essential time for tax compliance and planning. In this quarter, businesses should review their tax payments, liabilities, due dates and deadlines for payments and filings.
They also have to consider whether their income inflows tell them they need to pay more or less of estimated taxes. The IRS advises that not paying enough in estimated taxes can give rise to penalties, even in case of a taxpayer getting a tax refund later on.
Businesses should keep a tax calendar with the following data:
- Dates for federal taxes
- Requirements for state taxes
- Estimated tax payment due dates
- Payroll taxes
- Sales and use taxes
- Obligations towards information reporting
One can check for the latest updates on the federal Q4 deadlines using the IRS 2026 Tax Calendar.
Verify Fixed Assets, Depreciation, and Business Expenses
Prior to the commencement of the accounting procedures for year-end, conduct a review of your fixed assets schedule.
Make sure that the registered purchases of the equipment, vehicles, technology, and the assets meet the qualifications. In addition, verify the figures on depreciation and disposal of the assets.
At the same time, analyze expenses of the business to determine if any unusual or incorrect transactions were logged.
Maintaining accurate records of fixed asset and expenses will lead to:
- Improved financial reporting
- Precise depreciation
- Reliable preparation for taxes
- Clean end-of-year accounting
- Better financial making decisions
Now is also the time to collect the paper work that you may need from your accountant or tax advisor.
Review Financial Reports and Key Business Metrics
When your accounts are tidy, take a close look at your main finance records.
Following are the important reports for any firm:
- Profit & Loss
- Balance Sheet
- Cash Flow
- Accounts Receivable Aging
- Accounts Payable Aging
Then analyze how these reports affect important financial key performance indicators, such as revenue growth, gross profit margin, operating expenses, accounts receivable days, and current cash levels.
In other words, you ought to learn how to interpret what numbers tell you.
For example, when revenue rises but cash decreases, it means that debts collection, inventory, or payment cycle require special attention.
Prepare a Q4 Accounting & Tax Action Plan
In conclusion, you must turn your accounting review into practical plans for Q4. Compile a comprehensive list of remaining accounting, tax, payroll, and financial reporting assignments.
Your Q4 accounting checklist might include:
- finishing all reconciliations

- updating financial forecast
- creating the final documentation of the financial year
- formulating plan for end-of-year tax drive
