5 QuickBooks Mistakes Business Owners Commonly Make at the Start of a New Year

Running a business in Maryland requires more than just a great product or service; it demands a clear, accurate view of your financial health. As the calendar flips to January, many business owners rely on QuickBooks to set the tone for the coming year. However, the first few weeks of the new year are often the most precarious for your digital books. Between uncleared transactions from December and the pressure of upcoming tax deadlines, a few simple clicks can lead to months of “messy” data. 

At CFO Source, we’ve spent over 20 years providing executive-level financial oversight to central Maryland businesses. We know that a clean start in QuickBooks isn’t just about organized folders; it’s about ensuring your data is reliable enough to drive growth and keep you compliant with the IRS.

Here are five essential steps to prevent common New Year QuickBooks mistakes.

Neglecting the “Month-End” and “Year-End” Close

The most frequent mistake is moving into January without officially “locking” the previous year. If you don’t set a closing date and password in QuickBooks, it’s all too easy to accidentally post a new transaction to December or edit a reconciled entry from the prior year. This creates a nightmare for your CPA and can cause your opening balances to be incorrect. For a business scaling, data integrity is the foundation of any loan or investment conversation. 

Mixing Personal and Business Expenses

The start of a new year often brings “fresh start” spending, but using a personal card for a business software subscription or a new laptop is a major red flag. Commingling funds makes it incredibly difficult to track your true business profitability and can jeopardize the legal protections of your corporate structure. In Maryland, where tax audits can be rigorous, having a “clean” trail is your best defense. 

Failing to Clean Up the Chart of Accounts

Over time, your Chart of Accounts can become bloated with duplicate categories or “miscellaneous” buckets that hide where your money is actually going. Starting a new year with an unorganized list of accounts means your financial reports will be vague and unhelpful for strategic planning. If you can’t tell the difference between your marketing spend and your office supplies at a glance, you can’t optimize your budget.

Ignoring Uncleared Transactions in Reconciliation

Simply hitting the “Reconcile” button until the difference is zero isn’t enough. Many owners ignore “uncleared” transactions—checks that were never cashed or duplicate deposits that haven’t cleared the bank. These “ghost” entries stay in your books, artificially inflating your cash balance and distorting your true financial position. For a commercial enterprise, relying on a fake cash balance can lead to overspending and bounced payments. 

Misclassifying 1099 Vendors and Contractors

January is 1099 season, and one of the biggest mistakes is failing to verify vendor information before the filing deadline. If you haven’t requested W-9s or correctly marked your contractors in QuickBooks throughout the previous year, you’ll face a stressful scramble in late January. Incorrect classifications can lead to IRS penalties and missed tax deductions for your business.

Set Your Business Up for Success

Starting the year with a clean QuickBooks file is the best insurance policy you can have for your company’s financial future. When you take the time to lock your books and organize your data now, you avoid the frantic “cleanup” fees and reporting errors that plague so many Maryland businesses during tax season.
