For any business owner, tax season seems to catch you off guard each time. In one moment, you were thinking about customer relations, payroll, and growing your business, but then, all of a sudden, you were sorting through your bank statements and receipts to figure out what happened during the previous year. Organizing your bookkeeping before tax season is not only about following regulations. It is about understanding, confidence, and avoiding costly mistakes.

Proper organization of your books will help you save time and energy when preparing your taxes and, even more importantly, ensure there are no oversights or mistakes on your part. Therefore, organizing your books is crucial to the tax preparation process. By doing so in advance, you might discover some ways to improve your tax strategy and avoid unpleasant surprises. This blog explores how to clean up messy books before tax season.

What Does “Bookkeeping Cleanup” Mean?

Small-business bookkeeping cleanup refers to the practice of reviewing, correcting, and organizing your accounting records to provide an accurate picture of your business operations over a specific time frame. Bookkeeping cleanup differs from regular bookkeeping, as the latter involves recording transactions as they occur.

Bookkeeping cleanup may be necessary when you are falling behind on your books or when they contain inaccuracies. These situations arise after a year of being extremely busy, growing rapidly, or having irregular bookkeeping.

Some of the problems with bookkeeping that need cleanup are:

•          Unclassified revenues and expenditures
•          Lack of receipt documentation
•          Duplicate entries
•          Combination of personal and business expenses
•          Non-reconciliation of bank or credit card accounts

The importance of clean up messy books before tax season is to ensure your books are accurate and up to date.

Step-by-Step Cleanup Process

Bookkeeping cleanup need not be a daunting task. The whole process becomes much easier once broken down into well-defined bookkeeping cleanup steps.

Collect All Financial Documents

This is the first and most important step in the bookkeeping cleanup process. It requires you to collect all financial documents related to your business operations for a single calendar year.

These include:

•          Bank account and credit card statements
•          Sales invoices and customer receipts
•          Expense receipts, whether physical or digital
•          Payroll tax documents such as W-2 and 1099 forms
•          Statements from loan companies and interest income statements
•          Tax returns from prior years

Once you have collected all the documents, ensure that you store them all in one place. You may consider scanning all paper receipts and saving them in a digital format.

Reconcile All Accounts

Account reconciliation is the process of checking whether your bookkeeping system agrees with the figures on your bank and credit card statements.
Steps for account reconciliation include:
1.         Compare each bookkeeping entry against the bank statement
2.         Match dates and amounts
3.         Identify any missing, duplicate, or erroneous entries

It is necessary to reconcile the accounts before tax season comes. Without doing so, income or expenses may be under- or overstated. Moreover, the tax calculations will be inaccurate, resulting in tax filing errors.

Categorize Transactions


After reconciliation, examine how transactions have been categorized. Categorizing transactions accurately helps report expenses properly based on your chart of accounts.

Consider the following aspects:

•          Unassigned transactions clearing
•          Expenses review for accuracy
•          Differentiation of personal and business expenses
•          Tax income allocation to appropriate accounts

The improper categorization of transactions also affects deductions. Correct categorization makes the job of a tax preparer much easier.

Check Accounts Receivable & Payable

Finally, check how much money your clients owe you and how much your company owes its vendors.

Accounts Receivable:


•          Generate aging reports
•          Identify overdue invoices
•          Check open balances

Accounts Payable:

•          Check if there are unrecorded bills
•          Verify vendor balances
•          Look for duplicate or omitted liabilities

A good record of receivables and payables guarantees accurate reporting of income and expenses in the right periods.

Fix Errors and Missing Entries

Having made most of the necessary transactions, you need to go through your books for errors. Some of the typical mistakes you might make when recording transactions include:

•          Duplicate entries
•          Omissions in recording revenue
•          Classifying personal expenses as business expenses

Automated bookkeeping software such as QuickBooks will help you spot any duplicate entries in your accounting system. However, you should review your records to ensure all your transactions are recorded correctly. Be sure to check for anomalies that may be due to omissions.

Where you have classified personal expenses as business, be sure to correct them. Separating finances is an important practice to ensure accurate records and easier tax preparation.

Prepare Financial Statements Required for Tax Preparation

The last thing to do before filing your taxes is to prepare your financial statements. They include:

•          Profit and loss statement
•          Balance sheet
•          Cash flow statement

They provide the summary of your business operations during the year and form part of your tax returns.

Tips to Stay Organized Year-Round

It’s good to do annual cleaning, but good habits will help you organize your financial documents and simplify bookkeeping. Keeping up with bookkeeping throughout the year will save you from having to clean it up later. Think of the following best practices as a year-end bookkeeping checklist.


Best practices for business bookkeeping:

•          Account reconciliation monthly
•          Receipt uploading when making expenses
•          Quarterly review of financial reports
•          Bookkeeping reminder setting
•          Regular use of bookkeeping software

When to Get Professional Help

Certain bookkeeping clean-ups may be completed in-house through the procedures described above. In some cases, however, professional assistance may prove beneficial.
Indicators that you may need help with your bookkeeping include:

•          Out-of-date books by a few months or even years
•          Diverse accounts that have not been reconciled
•          Expense accounts that are confusing or not categorized correctly
•          Insufficient time to complete the bookkeeping clean-up process before the tax deadline

The combination of bookkeeping cleanup services and small-business tax preparation will minimize your stress and increase your accuracy.
