Frequently Asked Questions

What is the difference between a CPA and a regular accountant?

A CPA has passed the Uniform CPA Examination and met state licensing requirements, while a general accountant may not hold this credential. CPAs can represent you before the IRS, sign audit reports, and are held to strict ethical standards by their state board of accountancy.

How much does a CPA typically charge?

CPA fees vary by location and complexity. Simple individual tax returns typically cost $200-$500, while business returns can range from $500-$2,500 or more. Many CPAs also offer hourly consulting at $150-$400 per hour.

When should I hire a CPA instead of doing my own taxes?

Consider hiring a CPA if you are self-employed, own rental properties, have investment income, experienced major life changes like marriage or home purchase, or received an IRS notice. A CPA can often save you more in deductions than their fee costs.
