Frequently Asked Questions — CPAs & Accountants in Columbia
What is the difference between a CPA, bookkeeper, and tax preparer in Columbia?
A CPA (Certified Public Accountant) is licensed by the MD 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 MD?
Search the MD Board of Accountancy's online license lookup (find it by Googling "MD 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 Columbia?
Typical rates in Columbia: $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 Columbia 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.
