Frequently Asked Questions — CPAs & Accountants in O'fallon
What is the difference between a CPA, bookkeeper, and tax preparer in O'fallon?
A CPA (Certified Public Accountant) is licensed by the MO Board of Accountancy, can represent clients before the IRS, and carries liability coverage. A bookkeeper records day-to-day transactions but cannot sign tax returns or provide strategic tax advice. A tax preparer has no required credentials — anyone can prepare taxes. For business owners, complex returns, or IRS issues, a CPA is the right choice.
How do I verify a CPA's license in MO?
Search the MO Board of Accountancy's online license lookup (find it by Googling "MO Board of Accountancy license search"). You can also use NASBA's License Verification tool at nasba.org to search across all states. Always verify before sharing financial documents.
How much does a CPA charge in O'fallon?
Typical rates in O'fallon: $150–$400/hr for consultation; $300–$800 for a personal tax return; $500–$2,500+ for a small business return depending on complexity. Many CPAs offer flat-fee packages for straightforward situations. Get itemized quotes from at least 2–3 firms before committing.
Should I hire a local CPA or use online tax software?
Online software (TurboTax, H&R Block, FreeTaxUSA) works well for simple W-2 situations with no major life changes. A local CPA in O'fallon is worth the cost if you own a business, have rental income, experienced a major event (divorce, inheritance, home sale), owe the IRS money, or want year-round tax planning — not just annual filing.
How are the cpas & accountants on this page ranked?
Rankings use a transparent algorithm: star rating (35%), review volume (30%), customer sentiment (20%), profile completeness (10%), and availability (5%).
