What is the difference between a CPA and a tax preparer?
A Certified Public Accountant is licensed by the state after meeting education, examination, and experience requirements, and must complete ongoing professional education. CPAs can represent you before the IRS and provide tax planning and accounting advice beyond preparing a return.
Do you only work with local clients?
No. Our office is in Lake Forest, minutes from Irvine, and we work with clients across Orange County, throughout the United States, and internationally, including multi-state filers, U.S. expats, non-residents, and visa holders.
Can you help if I received a letter from the IRS or the state?
Yes. We review the notice, explain what it means, prepare a response, and can communicate with the agency on your behalf, including during audits.
Do I need tax planning, or just tax preparation?
Tax preparation reports what already happened. Tax planning looks ahead to legally reduce your taxes before the year ends. It is especially valuable for business owners, self-employed professionals, real estate investors, and anyone with a major financial change.
