Preparing QuickBooks for the 2025 Tax Season

As the calendar turns and tax season approaches, small-business owners and accountants face the annual task of preparing the previous year’s financials. If you are getting ready to file your 2025 taxes in 2026, the most critical step happens inside your QuickBooks company file long before you hand anything over to a tax preparer. A clean, reconciled set of books makes the entire filing process faster and far less stressful.

Here is our practical guide to getting your QuickBooks data organized and ready for the upcoming tax deadline.

Reconcile Every Account

Before generating any tax documents, ensure that every balance sheet account has been fully reconciled. This means matching your QuickBooks records against your bank and credit card statements for all twelve months of the tax year.

Pay special attention to clearing accounts, petty cash, and any loan accounts. Unreconciled discrepancies often hide missing expenses or unrecorded income that will need to be accounted for on your return.

Review Accounts Receivable and Payable

Outstanding invoices and unpaid bills can complicate your tax picture, particularly if you operate on an accrual basis. Review your Accounts Receivable (A/R) aging report to identify invoices that are unlikely to be collected. If a customer is never going to pay, you may need to write off the bad debt.

Similarly, review your Accounts Payable (A/P) aging report to ensure all legitimate expenses from the tax year have been entered, even if you have not paid them yet.

Clean Up the General Ledger

Scan your general ledger for common data-entry errors. Look for transactions that were coded to the wrong expense category, personal expenses that were accidentally recorded as business costs, or fixed asset purchases that were mistakenly expensed rather than capitalized.

If your file is unusually large or has been running for many years without a cleanup, you might consider condensing your QuickBooks company file to remove old, unnecessary data and streamline your year-end review.

Lock Down the Period

Once you are confident your books are accurate, use the QuickBooks closing date feature to lock the period. Setting a closing password prevents anyone from accidentally altering historical transactions after you have finalized the numbers for your tax return.

Export Your Reports

Finally, generate and export the core financial reports your tax professional will need. At a minimum, pull a Profit and Loss statement and a Balance Sheet for the full tax year. Having these documents finalized and saved as PDFs ensures you have a stable snapshot of your financial health to submit with your filing.
