Do I need a bookkeeper if I already have a CPA?

Yes, you almost certainly do. This is one of the most common questions I get, and the confusion makes sense: both professions work with your business’s money. But they do different jobs at different times of year, and each one works better when the other exists.

What your CPA does

Your CPA (or tax preparer) works mostly at the year level. They prepare and file your returns, advise on tax strategy and entity structure, and represent you if the IRS comes asking. It’s skilled, high-stakes work, and it’s mostly backward-looking: they take the records of what happened and file accurately on it.

Notice what’s missing: nobody in that job description is keeping your records week to week. Your CPA works from your books. They don’t build them.

What your bookkeeper does

A bookkeeper lives at the month level. Transactions categorized, accounts reconciled, reports produced, questions answered. By the time your CPA needs your numbers, the year is already organized, verified, and ready to hand over.

I keep my own lane deliberately: I don’t prepare taxes. I support your books all year and get them CPA-ready before deadlines. Because I’m not selling tax prep, my only agenda is records your tax pro can trust.

What happens when you have a CPA but no bookkeeper

I see 3 versions of this, and I’ve cleaned up after all of them:

1. The shoebox January. You hand your CPA a year of statements and receipts. They either send it back and ask you to organize it, or they charge CPA hourly rates to do bookkeeper work. Either way you pay more, and it happens during their busiest month.
2. The DIY drift. You keep the books yourself, mostly. Reconciliation slides. Categories get creative. Your CPA files from numbers that are approximately true, and approximately true numbers cost you: missed deductions, overstated income, or a return that draws questions.
3. The silent CPA. Your CPA quietly fixes what they can at year end, bills you for it, and never sees your business closely enough to advise on it. You have a strategist working from a blurry photograph.

What the 2 look like working together

With both in place, the year runs like this. Your bookkeeper closes each month: categorized, reconciled, reported. You read reports you understand and make decisions during the year, when decisions still help. Come tax season, your CPA receives a year of books that reconcile to the bank, with documentation for anything unusual. They file faster, they bill fewer cleanup hours, and their strategic advice is built on numbers that reflect reality.

When I take on a client who has a CPA, one of my first requests is an introduction. The more your bookkeeper and CPA are on the same page about your goals, the better both of us serve you.

The cost logic

Owners sometimes see a bookkeeper as a cost layered on top of the CPA. In practice the 2 offset. Clean books reduce CPA hours, catch deductions that sloppy records lose, and prevent the expensive January scramble. And the monthly reports give you something no once-a-year tax filing can: the ability to steer the business while the year is still happening.

If you have a CPA you like, keep them. Then give them the gift every CPA wants and few clients deliver: books that are already right.
