Start the New Year With Clean Books
- Bring unfinished bookkeeping up to date
- Reconcile bank and credit card accounts
- Review balances and correct bookkeeping issues
- Start 2027 with clean, current financial records
The end of the year is a natural checkpoint for your business books.
Before moving into 2027, take time to make sure transactions have been recorded, accounts have been reconciled, outstanding balances have been reviewed, and important financial records are complete.
Clean year-end books don’t just make tax preparation easier. They give you a reliable ending point for 2026—and a better starting point for understanding your business in 2027.
Here is what to review before closing out the year.
1. Make Sure All Transactions Are Recorded
Start by confirming that your bookkeeping is current through the end of the year.
Bank feeds can help bring transactions into accounting software, but downloading transactions is not the same as completing the bookkeeping. Transactions still need to be reviewed and categorized correctly.
Look for:
- Missing income or expenses
- Uncategorized transactions
- Duplicate transactions
- Transactions posted to the wrong accounts
- Business expenses paid personally
- Personal expenses accidentally recorded as business expenses
If your books are several months behind, address the backlog rather than simply starting fresh in January. Otherwise, unresolved 2026 activity can carry into the new year and affect your financial reports.
2. Reconcile Every Bank and Credit Card Account
Each business bank and credit card account should be reconciled through the final statement of the year.
Reconciliation compares the activity recorded in your accounting system with the activity reported by the financial institution.
Review:
- Checking accounts
- Savings accounts
- Business credit cards
- Lines of credit or other accounts with transaction activity
The ending reconciled balance should agree with the corresponding statement.
But remember: reconciliation alone does not mean the books are accurate.
A transaction can clear the bank and still be categorized incorrectly. That’s why reconciliation should be part of the bookkeeping review—not the end of it.

3. Review Accounts Receivable
If you invoice customers, review your accounts receivable aging report.
Look for invoices that are:
- Still outstanding
- Past due
- Duplicated
- Already paid but showing as unpaid
- Unlikely to be collected
Follow up on legitimate outstanding balances and investigate anything that doesn’t look right.
You don’t want to begin 2027 with an accounts receivable balance that includes invoices that aren’t actually owed.
4. Review Accounts Payable and Unpaid Bills
Do the same with amounts your business owes.
Review vendor bills and accounts payable for:
- Unpaid bills
- Duplicate bills
- Bills that have already been paid
- Old balances that should no longer be outstanding
- Expenses that were incurred but haven’t been entered
Accurate accounts payable helps ensure your balance sheet reflects actual business obligations at year-end.
5. Review Loans and Other Liabilities
Compare loan balances in your accounting system with year-end lender statements or other supporting records.
This can include:
- Business loans
- Lines of credit
- Vehicle loans
- Equipment financing
- Credit card balances
Loan payments frequently include both principal and interest. If the entire payment has been recorded as an expense, the loan balance and expenses may both be incorrect.
Investigate unexplained balances before carrying them into 2027.
6. Review Fixed Assets and Major Purchases
Identify significant purchases made during the year, such as:
- Vehicles
- Machinery
- Computers
- Furniture
- Equipment
- Other long-term business assets
Make sure these transactions are clearly identified and supported by purchase records.
Don’t assume every large purchase should simply be categorized as an expense. Your tax professional can determine the appropriate tax treatment based on the asset and your circumstances.
Keeping these purchases organized also makes tax preparation much easier.
7. Review Payroll Records
If you have employees, make sure your payroll records are complete before year-end reporting.
Review:
- Employee wages
- Payroll tax liabilities
- Payroll tax payments
- Employee information
- Benefits and other compensation
- Payroll clearing or suspense accounts, if applicable
Payroll recorded in the books should also be consistent with your payroll provider’s reports.
Resolving discrepancies before Forms W-2 and other year-end payroll filings are prepared can prevent unnecessary complications later.
8. Review Owner Transactions
Owner transactions are another area worth reviewing before closing the books.
Look for:
- Owner contributions
- Owner distributions or draws
- Business expenses paid personally
- Personal expenses paid by the business
- Transfers between personal and business accounts
These transactions should be identified and categorized appropriately rather than left in miscellaneous expense or uncategorized accounts.
For corporations and partnerships, the treatment of owner or shareholder transactions can be especially important. Ask your tax professional about transactions you’re unsure how to classify.
9. Collect Supporting Documents
Good bookkeeping isn’t only about what appears in the accounting software.
Make sure important transactions are supported by appropriate records, such as:
- Receipts
- Invoices
- Vendor bills
- Bank and credit card statements
- Loan statements
- Equipment or vehicle purchase documents
- Payroll reports
A clean general ledger is much more useful when the underlying transactions can also be supported.
Organizing records now can save considerable time when tax preparation begins.
10. Review Your Financial Statements
Once the bookkeeping work is complete, conduct a year-end financial review to understand what the financial statements are telling you.
At minimum, look at your:
Profit and Loss Statement
Does revenue, expense activity, and net profit make sense based on what happened during the year?
Balance Sheet
Do the bank, credit card, loan, receivable, payable, and owner-equity balances make sense?
Look for negative balances where you wouldn’t expect them, unusually large amounts, old balances, or significant changes you cannot explain.
If something doesn’t make sense, investigate it before treating the books as complete.
Clean Books Are More Than Reconciled Books
It’s possible for every bank account to be reconciled and for the financial statements still to contain errors.
Year-end bookkeeping should help confirm that:
Transactions are complete → Accounts are reconciled → Balances are supported → Financial statements make sense
That is what makes the books useful—not simply reaching a zero-dollar reconciliation difference.
Don't Carry 2026 Bookkeeping Problems Into 2027
Unfinished bookkeeping doesn’t disappear when the calendar changes.
If transactions are missing, accounts aren’t reconciled, or balances don’t make sense on December 31, those issues become the opening balances and historical records you’re relying on in 2027.
Cleaning them up before moving forward gives the new year a reliable starting point.
And once the books are current, they can also support tax preparation, tax projections, and year-end planning.
