What does a CPA do that a bookkeeper doesn't?
A CPA (Certified Public Accountant) holds a state-issued license that requires passing a four-part exam, meeting education requirements, and completing continuing education every year. That license allows them to do things a bookkeeper legally cannot. Filing tax returns, representing you in front of the IRS, signing off on audited financial statements, and providing formal tax advice all fall under the CPA’s scope.
A bookkeeper handles the day-to-day financial recordkeeping. Categorizing transactions, reconciling bank and credit card accounts, tracking accounts payable and receivable, and generating reports like profit and loss statements and balance sheets. This is foundational work. Without it, a CPA has nothing accurate to work with at tax time.
Think of it this way. The bookkeeper builds the financial picture of your business throughout the year. The CPA uses that picture to file your taxes correctly, find deductions you qualify for, and help you make decisions about things like equipment purchases, entity structure, or retirement contributions.
For trades and construction businesses, this distinction matters more than most owners realize. A plumber or general contractor who hands a shoebox of receipts to a CPA at year end is paying that CPA to do bookkeeping work first and tax work second. That’s expensive and it usually means deductions get missed because nobody was tracking things properly all year. Having bookkeeping for trades businesses handled consistently means your CPA can focus on the higher-level work that actually saves you money.
Where things overlap is that some CPAs also offer bookkeeping services, and some bookkeepers have enough experience to spot tax-related issues. But only a CPA can sign your tax return, respond to an IRS notice on your behalf, or give you formal guidance on tax planning strategies. A bookkeeper who tells you how to structure a transaction for tax purposes is operating outside their lane unless they also hold a CPA license or enrolled agent designation.
The practical takeaway for most small business owners is that you need both functions covered. Clean books throughout the year and a qualified professional handling business tax returns and strategy at year end. Whether that comes from two separate people or one firm that handles both, the important thing is that neither piece gets skipped. Accurate books without good tax work leaves money on the table. Good tax work without accurate books is guesswork.

What tax forms does an S-corp need to file?
Every S-corp files Form 1120-S with the IRS and a K-1 for each shareholder. Beyond that, you'll have payroll tax forms, state returns, 1099s for subcontractors, and your personal return where the business income actually gets taxed.
Read answerShould I track mileage or use actual vehicle expenses?

Read answerHow often should I reconcile my business bank account?
