Yes, you do. Your CPA or tax preparer needs accurate financial records to file your return correctly and on time. If your books are behind or disorganized, they can’t produce accurate numbers. That means potential errors, missed deductions, or delays that push you toward filing an extension.

Clean books for tax purposes means all bank and credit card accounts are reconciled through December 31. Every transaction is categorized properly. Expenses are matched to the right accounts. Revenue is recorded accurately. If you’ve been handling bookkeeping sporadically or not at all, those gaps need to be filled before anyone can prepare a reliable return.

The bookkeeping work and the tax filing are usually handled by different people. A Long Island bookkeeping service gets your financial records current and organized, then hands a clean QuickBooks file or set of financial statements to your CPA. When this handoff goes smoothly, tax season is straightforward. When it doesn’t, everyone scrambles.

Timing matters more than most business owners realize. Getting a full year’s books current can take anywhere from a few days to several weeks depending on how far behind you are and how complex your finances look. Waiting until March means your bookkeeper is rushed, your CPA is waiting, and mistakes become more likely. Starting in January or even late December gives everyone room to do the job properly.

Going to your CPA with messy or incomplete records often results in higher fees. They’ll either spend extra time sorting through transactions or make assumptions that could cost you deductions. Some CPAs won’t start on your return until they receive clean books, which puts the entire timeline at risk.

If you’ve fallen behind, the goal isn’t perfection. It’s getting your records to a point where they reflect reality. Catch-up bookkeeping brings your books current and makes sure your CPA has what they need without the year-end panic.
