Okay, let’s tackle this. So Mark Davidson has 38 years of experience as a CPA, which is extremely high. Typically, CPAs with this level of experience can charge higher rates. However, location is also a factor. Tulsa, Oklahoma is not a major hub for accounting and tax services. Let’s look at national averages. According to the Bureau of Labor Statistics, the median annual salary for accountants and auditors is around $74,000. However, experienced CPAs can earn significantly more. Some sources suggest that CPAs with 20+ years of experience can earn upwards of $150,000 per year. Considering Mark’s extensive experience and location, I estimate his hourly rate to be around $150, per hour.
