Before the Q4 Crunch: The Bookkeeping Cleanup That Makes January Easy
October is a quiet month for bookkeeping.
That is exactly why I like it.
There is still time to review your records, find small errors, and correct them during a normal monthly close or payroll run. You can ask questions while the transactions are fresh. You can fix missing information before year-end reports are prepared.
January is different.
A problem found in January may require a corrected W-2, an adjusted return, or a phone call explaining why two reports do not match. The work becomes louder. The choices become narrower. A simple October correction can become a January project.
My goal is to help you move from scattered records to perfect order before the Q4 crunch begins.
Why October is the right month to clean up
By October, you have nine months of business activity to review. You also have three months left to correct anything that is incomplete.
That creates a useful window.
You can:
Reconcile your records through the most recent closed month.
Compare payroll reports with your general ledger.
Correct missing or miscategorized transactions.
Confirm contractor information.
Check how overtime and tips are being recorded.
Review your estimated tax position before the year closes.
Every correction made now can fit into your regular bookkeeping rhythm.
Every correction made later may require extra research. It may affect a report that has already been prepared. It may need to be explained to an employee, contractor, tax preparer, or payroll provider.
This is not about creating fear. It is about choosing the quieter path.
1. Reconcile payroll to the general ledger
Start with the full year so far.
Do not review only September or only the third quarter. Compare your payroll register from January through the latest completed pay period with the payroll-related accounts in your general ledger.
Look at:
Gross wages.
Overtime.
Reported tips.
Employer payroll taxes.
Employee withholdings.
Benefits recorded through payroll.
Payroll liabilities.
Payroll-related reimbursements or adjustments.
The total payroll expense in your books should make sense when compared with your payroll reports. Your payroll liability accounts should also show a clear explanation for their balances.
Look for common differences:
A pay run missing from the general ledger.
A manual journal entry posted twice.
Payroll taxes recorded in the wrong account.
A voided check that was not removed correctly.
Benefits included in payroll but not in the books.
A liability balance that has remained unchanged for too long.
A correction made in the payroll system but not in the accounting system.
A difference does not always mean something is wrong. It does mean something needs to be understood.
If you leave the difference until December, it may be harder to identify which pay run caused it. The numbers compound. The details become less familiar.
A full year-to-date reconciliation now gives you time to correct the source.
2. Review overtime and tip reporting for 2026
The reporting process for certain overtime and tip amounts is new for tax year 2026. That makes this review especially important for businesses with hourly employees or tipped workers.
Your payroll system should be capturing the information it needs as the year progresses. Do not wait until year-end to estimate the amount from total wages or old timesheets.
Review whether:
Overtime hours are coming through from your timekeeping system.
The overtime premium is being tracked separately where required.
Reported tips from your point-of-sale system or employee reports are reaching payroll.
Cash and credit-card tips are being handled consistently.
Service charges are being distinguished from true tips.
Payroll reports and general ledger categories agree.
Your payroll provider is prepared for the new 2026 reporting requirements.
Separately reported overtime and tip amounts need to be supported by the records created during the year. If something was not captured correctly, it needs to be corrected. It should not be estimated later from memory.
This is a good time to ask your payroll provider a simple question:
“Are our 2026 overtime and tip reporting fields set up correctly, and are the amounts flowing into our bookkeeping records?”
A short conversation in October is much easier than rebuilding nine months of payroll information in January.

3. Confirm your contractor list and W-9 files
Contractor records are easier to review before you are under year-end pressure.
Run a list of everyone paid for services during the year. Then check the list against your books, payment records, and vendor profiles.
For each contractor, confirm that you have:
The correct legal name.
A current mailing address.
A completed W-9.
Correct payment details in your accounting system.
Payments categorized consistently.
Notes for unusual payments or reimbursements.
Watch for contractors who were added quickly during a busy season. Their vendor profiles may be incomplete. You may also find an old W-9 connected to a new business name or an outdated address.
This is also the time to separate service providers from vendors who only supplied goods. Clear vendor records make year-end reporting more orderly.
Do not wait until you are preparing contractor statements to discover that basic information is missing. Reaching out in October gives contractors time to respond without turning the process into a scramble.
4. Review your expense categories
Your expense categories should tell a consistent story from month to month.
Review your transactions from January through the latest closed month. Look for:
Personal expenses in business accounts
A personal purchase can slip into a business account when you are moving quickly. Reclassify it now so it does not remain in a deductible expense category.
Also look for owner transfers, personal subscriptions, household purchases, and mixed-use expenses that may need a separate review.
Missing receipts
Large purchases should have more support than a bank-feed description.
Look for missing receipts or invoices on:
Equipment.
Computers and technology.
Vehicles.
Furniture.
Advertising.
Travel.
Meals.
Professional services.
Add the receipt and a short note while you still remember the business purpose.
Inconsistent categories
The same type of expense should not move between several categories without a reason. For example, software may appear under office expenses one month and professional services the next.
Consistent categories make your financial reports easier to read. They also make tax preparation more efficient.
If you are unsure how to classify an item, mark it for review. Guessing creates more cleanup later.
5. Reconcile every bank and credit card account
Bring every business bank account and credit card account current through at least the most recent closed month.
Do not stop with the main checking account. Include:
Savings accounts.
Credit cards.
Business lines of credit.
Payment processor accounts.
Loan accounts, when applicable.
Accounts used for payroll or taxes.
As you reconcile, look for:
Duplicate transactions.
Missing deposits.
Uncleared checks that are no longer valid.
Old transfers.
Unrecorded fees.
Personal purchases.
Transactions posted in the wrong month.
Your reconciled balances should match the statements. If they do not, pause and find the reason before moving forward.
Clean reconciliations support everything else. They make your profit and loss statement more reliable. They help confirm that payroll payments and tax payments were recorded correctly. They give you a clearer view of available cash.

6. Confirm your estimated tax position
October is a useful time to review your expected full-year tax position.
Look at:
Year-to-date business profit.
Expected Q4 income.
Owner wages or distributions.
Prior estimated payments.
Major purchases.
Changes in household income.
Any new deductions or credits that may apply.
The purpose is not to predict the final tax bill perfectly. The purpose is to avoid a January surprise.
If your income is higher or lower than expected, your tax professional can help you decide whether your current estimates still make sense. A clean set of books makes that conversation much easier.
Your October list
Set aside one calm block of time this month and complete these seven tasks:
Reconcile all bank and credit card accounts through the latest closed month.
Compare year-to-date payroll reports with the general ledger.
Review 2026 overtime and tip reporting with your payroll provider.
Run a contractor list and confirm a current W-9 for each service provider.
Review expense categories for personal charges, missing receipts, and inconsistent coding.
Investigate old or unusual balances in payroll, credit card, loan, and transfer accounts.
Review your estimated tax position using updated year-to-date numbers and expected Q4 activity.
You do not have to complete everything in one sitting. Work through the list in order. Keep a short note of anything that needs follow-up.
Quiet work now creates an easier January
October bookkeeping is quiet work.
It is a steady review. A missing receipt. A corrected category. A payroll report that finally matches the ledger. A contractor file that is complete before anyone has to ask for it.
January work is louder.
The same issue may involve a corrected form, an adjustment, or several conversations to explain a difference. That does not mean January problems cannot be fixed. It simply means the work takes more time and attention.
