Customer Reviews

I've been very impressed with this CPA firm and Peter. They are trustworthy, honest, and always find a way to get things done. Highly recommended!

I have worked with this company before, but unfortunately, I feel their service quality has declined compared to a few years ago.

Peter Chun is great. He responds to your issue and questions quickly and he checks up on you often to make sure nothing falls behind or through the crack! My friends who I have referred to him have been his customers ever since they first met him. Definitely recommend.

This is the best CPA firm I've ever worked with. Mr. Peter Chun is very professional and knowledgeable, and always gives us useful suggestions on tax return. No matter how complicate our situation is, we can always get the most refund possible every year!

Our family has used Peter for 3 years and every year he has provided us with excellent service. Very prompt with all communication and has been very helpful and patient. One huge plus is I do not have to work with multiple people, I just deal directly with Peter. No hassle, no confusion. Thank you for you consistency and diligent service. I highly recommend them for small tax services to complicated ones.

We have been working with Peter Chun for the past couple of years, and we have appreciated his timely service and support. He has always been prompt in answering questions and accessible if we had any urgent needs. We have recommended him to our friends because of his friendly and professional service!

Peter and Company are great to work with. They are experienced, thorough and were able to identify and work on items that are most critical to my tax situations. Process-wise, almost turn-key and very efficient. Would work with them again, absolutely.

Peter Chun at Korus CPAs has been our corporate CPA for last 6 years and he is reliable, competent, and very professional. He has rescued our company from IRS audit fighting for us till we won with zero payment due to IRS. He always answered our calls or messages promptly with clear and substantive responses. We have been nothing but pleased with his efficient and diligent work.

Peter Chun at Korus CPA'S is a great person. He is not only a professional, but a very kind, courteous, wonderful and helpful human being. Peter goes the extra mile to help his clients, this is a big plus for KORUS CPA'S. I am extremely happy with the way Peter conducts himself, his service is excellent. Peter does not leave any stone unturned to achieve success and help his clients to mitigate their problems.

Peter Chun and his team are great - they never miss on the smallest detail and always make you feel like a valued customer no matter the size of your business. All my questions are anwered promptly and I would highly recommend their service to anyone.

Mr. Chun helped me to realize that I should never do my own taxes ever again! Thankfully he was able to identify all of my mistakes and do some major damage control for me. I definitely recommend leaving your taxes to professionals like Mr. Chun as well as to SEEK HELP even if you already messed it up!

Peter Chun and his firm, Korus are great CPAs. I have referred a number of clients to them. I am confident they will provide you with the best service at a competitive price.

Like most of you reading this review, it is difficult to find a good CPA for your personal and business tax issues. I have used many CPAs in the past, but none compare to KORUS CPAs, LLP. They handle all of my corporate and personal bookkeeping and tax issues and I am extremely pleased with their service. KORUS CPAs, LLP is always looking for ways to save on taxes and is very attentive and always responds to my emails/phone calls. I highly recommend!

Peter Chun is a great CPA. My husband and I highly recommend him. He is very knowledgeable and was great at answering all our questions.

Our experience was pretty poor. From constantly trying to receive answers, to simple mistakes being made on returns (some of which we caught and some we didn't) that cost us thousands. Also forgetting to file fees for our companies (causing headaches after we severed ties). To not even acknowledging us when we gave notice to discontinue services.

Peter is a great CPA he always have time for me. Extremely professional and detail. Thank you for all your help.

Peter Chun and his team at KORUS know what they are doing. Very happy with their professional services and quick responses!

Impressed by their professional and prompt service. They know what they are doing to save my W-2s and schedule E taxation issue.

It was great to work with Peter. Great personality and very easy to communicate.

They are very effective and thorough.

Good people! Good service!

They provided very professional and honest advice. This was by far the best place in Irvine and I decided to start managing my finances. Recommended.

Frequently Asked Questions

What qualifications should I look for in a CPA?

Look for a Certified Public Accountant (CPA) license, which ensures they’ve passed rigorous exams and meet state requirements. Check for relevant experience in your industry, additional certifications like CFA or CMA, and membership in professional organizations like the AICPA. Verify their credentials through state licensing boards.

How do I find a CPA in my area?

Use online directories like the AICPA, CPAverify, or state CPA societies. Search platforms like Yelp or Google for local CPAs with reviews. Ask for referrals from business associates, friends, or financial advisors. Local chambers of commerce can also provide recommendations.

What’s the difference between a CPA and an accountant?

A CPA is a licensed professional who has passed the CPA exam and met state requirements for education and experience. An accountant may lack this certification and could have varying levels of expertise. For complex tasks like tax audits or financial reporting, a CPA is typically more qualified.

How do I know if a CPA specializes in my needs?

Ask about their experience with your specific financial needs, such as tax preparation, small business accounting, or estate planning. Review their website or LinkedIn for case studies or client testimonials. Inquire about their client base to ensure they handle similar financial situations.

Should I check a CPA’s reviews before hiring?

Yes, reviews provide insight into a CPA’s reliability, communication, and performance. Check platforms like Google, Yelp, or the Better Business Bureau for client feedback. Look for patterns in reviews, but verify their authenticity, as some may be biased or outdated.

How can I verify a CPA’s license?

Visit your state’s Board of Accountancy website or use CPAverify.org to check a CPA’s license status. Confirm their license is active and check for any disciplinary actions or complaints. This ensures they’re in good standing and meet professional standards.

What questions should I ask during a CPA consultation?

Ask about their experience with your financial needs, fee structure, availability, and communication style. Inquire how they handle tax filings, audits, or financial planning. Ask for references or examples of similar work to assess their expertise and fit.

How much should I expect to pay for a CPA’s services?

Fees vary based on location, services, and complexity. Basic tax preparation may cost $150-$500, while business accounting or audits can range from $1,000 to $10,000+. Request a detailed fee structure upfront and compare quotes from multiple CPAs.

Can I work with a CPA remotely?

Yes, many CPAs offer remote services through secure online platforms for document sharing and virtual consultations. Ensure they use encrypted tools for data security. Remote CPAs can be effective if they understand your local tax laws or business regulations.

How do I assess a CPA’s communication skills?

During consultations, evaluate their ability to explain complex financial concepts clearly. Ask sample questions about taxes or financial strategies and note their responsiveness and clarity. Good communication ensures you understand their advice and fosters a productive relationship.

What red flags should I watch for when screening a CPA?

Beware of CPAs who guarantee specific tax refunds, lack a valid license, or have disciplinary actions on record. Avoid those with poor communication, vague fee structures, or negative reviews highlighting unethical behavior. Always verify their credentials independently.

Should I choose a CPA from a large firm or a solo practitioner?

Large firms offer more resources and specialized teams but may charge higher fees. Solo practitioners often provide personalized service and lower costs but may have limited availability. Choose based on your needs, budget, and preference for personalized attention.

How often should I meet with my CPA?

For individuals, annual meetings for tax preparation may suffice. Businesses may need quarterly or monthly check-ins for bookkeeping, tax planning, or financial reporting. Discuss your needs upfront to establish a meeting schedule that aligns with your financial goals.

Can a CPA help with both personal and business finances?

Yes, many CPAs handle both, but confirm their expertise in both areas. Ask about their experience managing personal taxes and business accounting simultaneously. Ensure they can balance both without compromising attention to your specific financial needs.

What should I do if I’m not satisfied with my CPA?

Discuss concerns directly with your CPA to resolve issues. If unresolved, check your contract for termination terms. Seek a new CPA by researching reviews, credentials, and referrals. Request your financial records to ensure a smooth transition to a new professional.
