How cpa works
CPA licensing is state-specific in the United States, requiring a set number of college credit hours, often 150, passing all four sections of the CPA exam, and completing supervised work experience before the license is granted. CPAs must also complete continuing education to keep the license active, and the credential is legally protected, meaning only licensed individuals can use the title even if they perform similar accounting work.
A CPA's work ranges from tax preparation and planning to audits, reviews and compilations of financial statements, services a bookkeeper is not licensed to provide. Many small businesses use a bookkeeper for monthly transaction work and rely on a CPA separately for annual tax filing, strategic tax planning, or any engagement that requires a licensed signature, splitting the recurring and the statutory work between the two roles.
Example
A small manufacturing business uses a dedicated bookkeeper to reconcile accounts and close the books monthly, then sends the finalized year-end financial statements to its CPA. The CPA reviews the figures, prepares the corporate tax return, and signs it as the paid preparer, a step the bookkeeping team is not licensed to perform.
CPA in QuickBooks Online vs Xero
CPAs commonly work in QuickBooks Online, Xero or a tax-specific platform such as Lacerte, Drake Tax or UltraTax, pulling finalized general ledger data to prepare returns. Clean, closed books handed off by a bookkeeper or controller reduce the back-and-forth a CPA needs during tax season.
Common mistakes
- Assuming any bookkeeper can be called a CPA, which misrepresents the person's actual license and can create legal exposure since the CPA title is legally protected in every US state.
- Handing a CPA a year of uncategorized transactions instead of monthly closed books, which drives up preparation fees and slows down the return during the busiest time of year.
- Treating a CPA relationship as a once-a-year task instead of an ongoing one, which misses planning opportunities that only make sense when discussed well before year end.
Why it matters
A CPA's license lets them sign a return and represent a business before the IRS, an accountability a bookkeeper cannot provide, so knowing which role does what protects a business from relying on the wrong professional for a compliance step. For a business or accounting firm, handing a CPA clean, closed books instead of a shoebox of transactions saves money in preparation fees and speeds up filing during tax season.
